What is Scan-to-BIM?

Scan-to BIM is the process of capturing as-built details of an existing building or site with 3D laser scanning technology and processing that data into a BIM model. Thus, the site is “scanned” and converted to “BIM.”

How are As-Built Details Captured?

3D laser scanning is a fast and accurate method to collecting the as-built details of a building or site. 3D laser scanners use laser technology to record precise locations and measurements of every physical and visible detail of a site. A laser is emitted from the scanner, bounces off surfaces and returns to the scanner. The time it takes to bounce back to the scanner is recorded, calculating the distance using the velocity of light.

To give you a sense of the enormous number of points captured, the Leica RTC360 laser scanner records two million points per second with 2-6mm accuracy. The accuracy of points captured depends on the level of detail your project requires and can range from 2mm to 20mm depending on the laser scanner used. Site data is collected in three-dimensional points, each with its own X, Y, and Z coordinate. All of the data is tied together to create a point cloud of the building or site.

What is a BIM Model?

A BIM model is a digital representation of a building or site that includes geometric and non-geometric data. BIM models are information rich, and may include detailed physical characteristics, materials, and systems.

‍

How is a 3D BIM Model Created?

The GPRS Mapping & Modeling Team uses the point cloud to create a highly detailed and accurate 3D BIM model of the site. A CAD technician must be highly trained in the AEC industry to develop an accurate 3D BIM model. They need to know how a building is actually designed in order to make the model useful to an architect or engineer.

Software such as Autodesk Revit, ReCap, BIM 360, Navisworks, Inventor, SolidWorks and MicroStation can be used to create the BIM model. This software can document a building by creating a parametric three-dimensional model that includes both the geometry and non-geometric design and construction information.

Separate 3D BIM models can be created for each discipline, for example, architectural, structural, process mechanical, HVAC, plumbing, fire protection, and electrical.

Can You Create Other Deliverables From the 3D Model?

From the 3D model, 2D CAD drawings can be created with accurate and detailed technical information, such as site plans, floor plans, interior elevations, exterior elevations, sections, details, isometric drawings, mechanical and electrical drawings, and reflected ceiling plans, to name a few. A BIM model can also be a good basis for an engineer to create P&ID's for their client.

Custom analysis and calculations can also be created with great accuracy. Information such as prefabrication measurements, deformation analysis, wall plumb analysis, volume calculations, floor flatness and levelness analysis, and surface areas can be extracted.

How Accurate is the Point Cloud Data and BIM Model?

‍Point clouds are a digital representation of spatial information, stored as a collection of points with three spatial coordinates. They are hyper-accurate, within millimeters, and are scanned in the level of detail required for your project.

BIM model features are created to your project-specific scope. Models can be created with different levels of detail and tolerances, depending on what the clients’ needs are for the model. By specifying scope and project details, BIM models can be created correctly and accurately.

‍
What is Scan to BIM Used For?

BIM models provide a comprehensive view of a building that can be used throughout its lifecycle – during the design phase, construction phase, and operation phase of the building. The BIM model can be used during the design and planning stages of a project from design changes to material selection, and cost estimation. During the construction phase, the model can be used to coordinate and manage different trades and ensure the building is constructed according to the design intent. During the operation phase, the model can be used to manage maintenance and repairs, track the performance of the building, and plan for future improvements.

The 5 Most Asked Questions On 3D Laser Scanning

‍

1. What is 3D Laser Scanning?

3D laser scanning captures as built documentation for existing buildings or sites. Once data is acquired, a point cloud is generated and used to develop 2D CAD drawings or 3D BIM models, expediting the design, planning and development of projects.

‍

2. How Does Laser Scanning Work?

One primary method is that a laser scanner sends light pulses at high speeds which reflect off objects and return to the scanners’ sensor. For each pulse, the distance between the scanner and object is measured by determining the elapsed time between the sent and received pulses. Each point of the scan will be converted to a pixel with a known x-, y- and z- coordinate. Laser scans are taken in multiple positions around a site from varying viewpoints. Millions of data points are captured and processed into a point cloud, creating an accurate data set of the structure or site.

‍

3. Why is a Point Cloud Important?

Point clouds provide powerful and dynamic information for a project. By representing spatial data as a collection of coordinates, point clouds deliver large datasets that can be mined for information. The visualization and analysis from this data is invaluable for decision making. CAD technicians transform point clouds into customized deliverables used for visualization, analysis, design, construction, renovation, prefabrication and facility modifications.

‍

4. What are the Benefits of 3D Laser Scanning?

Sites are captured in high detail the first time, eliminating the need for return visits. High speed data collection expedites time-sensitive projects or those that require minimal disruption.

According to studies by the U.S. Energy Information Administration, gas utility use in the U.S. has grown significantly, increasing by 77% over the past three decades.

Just ten or fifteen years ago, gas shut-off procedures required a scheduled technician to come on site and manually shut off the gas to the building or structure. This process was time-consuming, costly, and sometimes extremely unsafe. However, technological advancements have streamlined many processes, introducing new remote capabilities once thought impossible.

The future promises further advancements in remote technology, including gas utility monitoring and shut-off systems. These innovations aim to improve operational efficiency and prioritize safety by leveraging technologies like ground-penetrating radar (GPR). Such advancements in remote utility management could revolutionize gas utility networks.

The Importance of Remote Monitoring and Shut-Off Systems for Gas Utilities

Gas utilities play a crucial role in providing energy to homes, businesses, and many other  industries. However, managing gas distribution networks comes with inherent challenges, including safety risks, operational complexities, and the need for rapid response to emergencies such as leaks or ruptures. The Environment America Research & Policy Center and Frontier Group released a report that found the United States had almost 2,600 gas pipeline leaks from 2010 through the end of 2021 that were serious enough to report to the federal government. That’s the equivalent of having one gas leak every 40 hours! Remote monitoring and shut-off systems offer proactive solutions to these challenges by providing real-time data insights and enabling remote control capabilities.

These incidents mentioned in the study above have killed 122 people and injured 603 people. Further, the total costs in property damage, emergency services, and the value of the lost gas totaled nearly $4 billion.  Remote monitoring and shut off systems help prevent tragedies just like these.

Many companies use a sensaphone system for remote gas monitoring. The sensors monitor wells’ wet levels, temperature, flow, equipment, and power failure.

• ‍Sensaphone Sentinel: A cellular-based monitoring system that accesses real-time data and offers data logging and reporting abilities. The system also monitors up to twelve environmental and equipment conditions, such as oil tank levels, pump status, and security
• ‍Sensaphone Sentinel PRO: A cloud-based monitoring system that comes with a cellular modem that monitors remote oil locations. This includes the monitoring of input/output points from third-party Modbus sensors, transducers, and PLCs

The Use of RGS Devices

Sensus, a utility infrastructure company, has collaborated with gas industry engineers to develop the first stand-alone Remote Gas Shutoff (RGS) device. This programmable device allows operations personnel to efficiently and remotely perform tasks ranging from gas meter shut-off to safety monitoring.

Previously, technicians needed to visit sites for these tasks. Now, using the Sensus RSG or similar devices, they can monitor and shut off utilities remotely. Companies and professionals can safely discontinue service on the first call using a handheld or vehicle-based transceiver for the RSG. Alternatively, with the Sensus FlexNet™ fixed-base communications system, service can be remotely shut off from the call center.

The Sensus RGS unit streamlines gas utilities, enhancing shut-off and safety monitoring processes. It offers remote pressure monitoring capabilities, enabling viewing of service line pressure at individual residences without requiring a technician to set a gauge. For added safety, users can program high or low pressure limits that automatically shut off service if these limits are exceeded. Additionally, the unit can automatically shut off service in response to vibration detection, such as seismic activity.

The RGS-10 features time-stamped tilt and tamper detection alarms, alerting utility managers to potential gas theft. With no exposed electronics, the product meets strict utility safety requirements and guidelines. Its design is resilient to dirt buildup, self-exercising to clear debris when necessary. The device includes numerous other features and possibilities.

Manufactured from cast iron in either angle or straight-body configurations, the device also has a UV-stabilized polycarbonate cover. It can be added to any type of residential meter set. When combined with accurate utility mapping, such as that provided by SiteMap® (patent pending) powered by GPRS, the possibilities are endless. Accurate utility mapping ensures proper installation and maintenance in various scenarios, extending beyond residential utilities.

Benefits of Remote Monitoring and Shut-Off Systems

These systems contribute to operational efficiency and cost-effectiveness by:

• Optimized Maintenance: Predictive maintenance based on real-time data helps prioritize and schedule maintenance activities, reducing downtime and extending asset lifespan. This style of maintenance helps reduce costs and keeps the clusters of society along our millions of miles of utility lines safe
• Resource Optimization: Efficient deployment of resources, such as maintenance crews and equipment, improves response times and minimizes operational costs. The sooner an incident is detected, the sooner it may be resolved.

Compliance and Regulatory Requirements

Remote monitoring systems aid utilities in meeting regulatory standards and compliance requirements by:

• Data Logging and Reporting: Continuous monitoring and data logging ensure accurate record-keeping. When records are properly kept, compliance audits and regulatory reporting can be maintained and facilitated
• Proactive Compliance: Early detection of issues helps utilities stay ahead of regulatory changes and requirements

GPR and Its Role in Gas Utility Monitoring

Ground-penetrating radar (GPR) is a non-destructive geophysical method that uses radar pulses to image the subsurface. In the context of gas utilities. GPRS is a leading provider in utility locating services. GPRS's field-to-finish process is underpinned by our 99.8% accuracy rate. Our elite team of SIM-certified Project Managers employ various collection devices such as ground penetrating radar, electromagnetic induction, CCTV crawler cameras, LiDAR (3D laser scanning), and acoustic leak detectors to gather built world data. This data is then compiled into whatever deliverables you require by our in-house Mapping and Modeling Team. These drawings, maps, and models are delivered and stored within the Digital Plan Room of our infrastructure management software application, SiteMap^®.

GPR offers several advantages:

Utility Line Detection and Mapping

GPR can accurately detect and map underground utility lines, including gas pipelines, without the need for excavation.

Accurate Location Mapping

GPR scanning (among other technology) provide precise location data of buried gas pipelines, enabling utilities to create detailed maps and as-built documentation. GPRS takes precision seriously, boasting and maintaining a 99.8% accuracy level over half a million jobs nationwide.

Identifying Anomalies

GPR can be used to help detect anomalies such as leaks, voids, or encroachments near pipelines, allowing for timely maintenance and repairs.

Enhanced Safety during Excavation

Prior to excavation or construction activities near gas pipelines, GPR assessments help you to:

• Conduct Risk Assessments: Identify potential hazards and utilities that may be impacted by excavation, reducing the risk of accidental damage and associated safety hazards. GPRS recommends annual inspections for your utilities and other facilities to ensure safety and line vitality
• Compliance with Regulations: Ensure compliance with safety protocols and regulations governing excavation near utility lines
• Integration with Remote Monitoring Systems: Integrating GPR data with remote monitoring systems enhances the overall effectiveness of gas utility management
• Real-time Data Integration: GPR data can be integrated into remote monitoring platforms, providing operators with comprehensive insights into underground conditions and potential risks. When utility lines are accurately mapped, they can also be accurately monitored, including with remote monitoring systems
• Safety and Maintenance: Early detection of subsurface anomalies through GPR facilitates proactive maintenance planning and reduces the likelihood of costly repairs, or fatal disasters. When gas lines are mapped, proper monitoring systems may be installed. These systems can detect an issue before it becomes a catastrophe. GPRS recommends that all gas lines are detected regularly, especially those in highly urbanized development areas

Trends and Innovations in Remote Monitoring and Shut-off Systems

We have already come quite the way in terms of utility line monitoring and safety. Remote monitoring and shut off devices are becoming more popular, and for good reason. These devices help reduce costs and risks associated with gas utility lines. When combined with technology and services like what GPRS offers, these systems become even more efficient.

Several trends and innovations are bound to shape the future of remote monitoring and shut-off systems for gas utilities:

• Advancements in Sensor Technology: Continued development of sensor technologies will enhance the accuracy and capabilities of remote monitoring systems
• Miniaturization: Smaller, more robust sensors will enable wider deployment across extensive pipeline networks, capturing detailed data on localized conditions. Think about what happened to memory cards, they keep getting smaller, and we keep fitting more data onto them. The same has happened with cameras, and most other modern technologies. It’s easy to say that these remote monitoring systems will also trend in the same direction
• IoT Integration: Integration with Internet of Things (IoT) devices will enable seamless data transmission and real-time monitoring capabilities. Many systems, such as traffic lights, and other daily-use technologies are already integrating IoT technology. It makes sense that remote monitoring and shut off systems will follow the same path
• Predictive Maintenance: AI algorithms will likely start to predict equipment failures and performance degradation. This advancement may allow project managers to preemptively address issues and optimize maintenance schedules
• Pattern Recognition: ML algorithms will likely enhance anomaly detection, identifying subtle deviations in data that may indicate potential risks or inefficiencies

Remote monitoring and shut-off systems are still not as widely used as you might expect, despite their surging popularity. The integration of technologies like GPR can enhance the capabilities of these systems by providing accurate subsurface data, which can then be used in a variety of ways to help support the installation and management of these new devices.

By embracing these technological advancements gas utility companies and professionals can optimize operations, reduce costs, reduce risks, and even maintain infrastructure integrity and longevity.

We've all heard the saying that less is more. This often rings true in the construction industry.

Lean construction has been making waves over the past few years, offering what many consider a superior method for building our world.

Efficiency and waste reduction are universal goals. Various methodologies have emerged over time to streamline processes and conserve resources. Lean Construction promotes a philosophy focused on maximizing value and minimizing waste throughout the building lifecycle. Recently, the integration of Geographic Information System (GIS) platforms with Lean principles has revolutionized the construction industry. But how exactly does this powerful combination help reduce waste and boost efficiency?

Understanding Lean Construction

Lean Construction, inspired by Lean Manufacturing principles, aims to deliver maximum value to customers while minimizing waste. In The Foundations of Lean Construction, the authors liken the realization of achieving reliability to the exhilaration of learning to ride a bike—suddenly, there's a newfound sense of freedom, speed, and range. Originating from the Toyota Production System in the automotive industry, Lean principles have been adapted to various sectors, including construction. At its heart, Lean Construction emphasizes collaborative planning, continuous improvement, and the elimination of non-value-added activities.

In Lean Construction, the focus shifts from individual stakeholders concentrating solely on their specific roles to all stakeholders working together as a cohesive team toward a unified goal. By applying even a few Lean Construction principles, a project gains additional dimensions as participants consider its entire life cycle.

The History of Lean Construction

The term Lean Construction was coined by the International Group for Lean Construction (IDLC) upon its founding in 1993. Used in this exact context, “construction” includes the entire industry and not the phase during which physical building takes place. Because of this contextual fact, Lean Construction involves even architects, designers, engineering, constructors, and suppliers, and others working in a field or task which the principles could apply.

In 1997, Glenn Ballard and Greg Howell started the Lean Construction Institute to develop and share information while working toward improving the management of construction projects. Through plenty of research and data analysis, it was found that only a little more than half of the assignments made by foremen which were supposed to be completed in a week were completed on time. Historically, the focus of improvement has been productivity on a worker level. However, Ballard and Howell felt that this approach to project management missed the root causes and resulted in an unpredictable workflow.

This led to the idea that the construction industry faced many similar challenges that were seen in the manufacturing sector. They then began to implement many of the principles of the Toyota Production System and Lean production methodologies and adapt them for use in construction.

Key Principles of Lean Construction

Much like lean manufacturing, the art of Lean Construction seeks to create production systems that minimize the waste of time, materials and even efforts in an attempt to produce the most value for the customer, while using the least amount of resources. There are many key principles and concepts, including, but not limited to:

Value Stream Mapping: Identifying and optimizing the very sequence of activities that can and will deliver value to the customer

Last Planner System: Enhancing coordination among project participants to ensure reliable workflow, without interruption, and minimal stutter

Pull Planning: Scheduling activities based on actual project demand rather than just the forecasts

Kaizen: Continuous improvement through small, incremental changes

5S: A disciplined approach to maintaining order in the workplace. The 5S words are Sort, Set in Order, Shine/Sweep, Standardize and Self-Discipline/Sustain

Choosing by Advantages (CBA): CBA is a tested and effective sound decision-making system developed by Jim Suhr in 1999. This is used for determining the best decision by looking at the advantages of each option

First-run Study (FRS): This is a trial execution of a process in order to determine the best means, methods, sequencing, and so on. FR studies are done at least a few weeks ahead of the scheduled execution of the process

Five Big Ideas: A set of organizing concepts that support Lean Project Delivery

Gemba: A Japanese term for where value is added or where the work takes place. Lean experts encourage “going to the gemba” to see  where there is opportunity to eliminate or reduce waste

Kanban: A Japanese term meaning "a signboard." The signal tells workers to pull parts or refill material to a certain quantity used in production

Mura: Japanese word for "Unevenness" - fluctuation in demand that causes the workflow to be uneven

There are many other terms associated with lean principles and philosophy. These terms may also be applied to other avenues of production and of life itself.

Lean Construction works and may be ushering the industry into an era of sustainability and frugality. When you’re able to do more with less, you’re able to strip away the extras that in turn also slow your team down. A 2018 study found that companies using the most effective lean methods completed 45% of projects early and delivered 70% of them under budget.

The Role of GIS in Lean Construction

GIS technology has quickly advanced beyond traditional mapping and spatial analysis, becoming a crucial tool in Lean Construction. GIS platforms integrate geographical data with project management processes, enabling better decision-making, reducing inefficiencies, and improving overall project outcomes. GIS itself operates with leanness in mind, utilizing fewer physical resources than traditional mapping and information systems.

Improved Collaboration and Communication

Effective communication and collaboration are critical to Lean Construction success. GIS platforms provide a centralized system where all stakeholders—architects, engineers, contractors, and clients—can access and share real-time data and project information. This transparency fosters collaboration, reduces misunderstandings, and accelerates decision-making processes, ultimately minimizing delays and cost overruns.

Enhancing Workflow Efficiency

GIS plays a pivotal role in optimizing workflow efficiency by providing spatial insights that inform project sequencing and resource allocation. For instance, GIS can help determine the most efficient routes for equipment and materials delivery, reducing travel time and fuel consumption. Moreover, real-time data updates allow project managers to promptly address issues and adapt plans as needed, ensuring smooth project progression.

Sustainability and Environmental Impact

Incorporating GIS into Lean Construction practices contributes to sustainability efforts by minimizing environmental impact. GIS helps assess the ecological footprint of construction activities, enabling proactive measures to protect sensitive habitats and conserve natural resources. By optimizing transportation routes and reducing material waste, GIS supports sustainable construction practices aligned with environmental stewardship principles. When you know where things are, and where the issues lie, you’re able to better contain them and maintain them, helping reduce environmental impact. SiteMap® is backed by the 99.8% accuracy of GPRS utility locates, meaning your data isn’t just easy to access, but it's also accurate as well. Greater accuracy leads to greater sustainability.

Implementing GIS in Lean Construction: Challenges and Considerations

While the benefits of integrating GIS with Lean Construction are substantial, implementation can present challenges that require careful consideration:

Data Integration: Ensuring compatibility and seamless integration of various data sources (e.g., CAD drawings, survey data, environmental data) into the GIS platform. SiteMap® makes it easy to integrate lean construction practices, as well as a wide variety of data sources. With SiteMap^®, your as-builts, survey data, environmental data, CAD drawings, aggregated maps, and much more can easily be stored, searched, and shared with anyone who needs them.

Skill Development: Most integrations would require adequate training to construction teams on GIS software and spatial analysis techniques. With SiteMap®, training isn’t required, as the platform is made with ease of use in mind. Anyone is able to use SiteMap^®, even those who have no experience or training.

Cost Considerations: Traditionally, initial setup costs and ongoing maintenance of GIS infrastructure may pose financial challenges for some construction firms. However, with SiteMap®, even financial challenges can be lean. While there may be some upfront costs, the amount of money saved thanks to fewer accidents, greater efficiency, fewer resources needed, and other aspects of integrating a platform like SiteMap® to help guide your lean construction endeavors is endless.

Addressing these challenges requires commitment from project stakeholders and your team, as well as a strategic approach to technology adoption. Investing in innovative and comprehensive GIS solutions tailored to construction industry needs can yield long-term benefits in terms of efficiency gains, cost savings, and improved project outcomes.

The construction industry sees nearly 800 deaths and thousands of injuries per year. The philosophy of Lean Construction as well as the talented and dedicated members of LCI is focused on doing more with less, resulting in less death, less injury, and more productivity and results. GPRS and SiteMap^® offer services and technology that support a lean construction philosophy, helping you visualize your world as you build it.

The integration of GIS platforms with Lean Construction principles marks a significant union that allows these principles to take on greater meaning and new form. By leveraging spatial data analytics, enhanced collaboration, and streamlined workflows, GIS empowers construction firms to achieve greater efficiency, reduce waste, and uphold sustainability objectives. By embracing GIS in Lean Construction, there is hope and promise to reshape project delivery methods, setting new benchmarks for innovation and excellence in the built environment.

As construction projects become increasingly complex and global demand for sustainable practices becomes not just a want, but a very serious need, SiteMap^® and GPRS are helping to drive a revolution that promises a more efficient and collaborative future for the construction industry and beyond. Do more with less; do more with SiteMap^® and GPRS.

At GPRS, we bang the drum about the power of leak detection and water loss surveys, and we wonder if anyone is listening.

Would a $54.7 million dollar water bill get your attention?

Here’s a brief case study that quite literally makes the case that any large facility or municipal manager needs to convince stakeholders and government to put annual water loss surveys into their budget – because the cost to this one industrial facility was $5,000 per day – for a leak in the fire suppression system they’d known about since the late 1980s!

How much water do you have to be losing to cost yourself an extra $5,000 per day in water bills?

500,000 gallons. Per day.

No one can say with any certainty when the leak became that big, but an educated guess would put it on the timeline where the now long-retired facility manager made the decision to install a secondary jockey pump “the size of a 55-gallon barrel” to keep the fire loop’s water pressure up.

“Every fire loop system has a jockey pump that comes standard. It’s just there to keep the system pressurized should there ever be a fire, and it starts spraying water to put the fire out. It has to keep pumping water into the system. Instead of repairing the leak, they put another jockey pump in. This one was approximately the size of a 55-gallon barrel,” said GPRS Leak Detection Project Manager, Derek Kauffman.

“At some point, it got so bad that both jockey pumps were running simultaneously, constantly, just day and night.”

Testing revealed that the fire loop was losing 500,000 gallons of water daily.

Conservatively speaking, the second jockey pump installation would have occurred somewhere in the early 1990s. Which means this single facility may have lost half a million gallons of water per day, every day, for 30 years.

Again, conservatively speaking, that would add up to 5.5 billion gallons of water. We can’t call it non-revenue water per se, because the facility certainly paid their utility bill, which would have run an additional $5,000 per day over their normal usage…

$5,000 x 365 x 30 = $54.7 MILLION DOLLARS.

Now, those millions were spread out year over year, but that’s still an additional $1.82 million in water bills for each year the leak was that severe.

How Didn’t They Know They Had a Giant Leak?

The short answer is, they knew they had a leak, but they had no idea how expensive, large, or potentially dangerous it was.

The facility, located in Oregon, was constructed in the 1980s. The first mention in their facility infrastructure records of a leak comes up in the late 1980s. It was sometime after that, that the then-facility manager made the determination that the solution was to keep the pressure up, rather than locate and fix the fire suppression leak.

Why Didn’t They Fix The Leak?

Up until the last 20 years or so, as leak correlator technology has joined acoustic leak detection to pinpoint pressurized leaks, the most common way to find a water line leak was to daylight it.

Daylighting, also called potholing, is when you break ground so that you can physically inspect a utility line. There are some common-sense guidelines when it comes to daylighting water lines – such as being aware of the most likely areas to suffer a line rupture – but in reality, the facility manager just takes a shot in the dark. If they are wrong, they’ll fill in that hole, and go dig another, and on and on until they find their leak.

You can imagine how time consuming, expensive, and frustrating “playing whack-a-mole” with a water leak would be in that situation.

Another way they’d be aware of the severity of the leak is if there were surface indicators like standing water, sinking pavement, etc. In the case of this facility, however, there were no surface indications of a massive leak. So, to the untrained eye, and ear, that giant jockey pump was doing its job, even if it cost more.

GPRS Project Manager Kauffman, said, “When I asked my site contact what evidence they had that the system was leaking, he told me there was not a single drop of water that could be seen surfacing.”

How Did GPRS Find The Leak?

When the facility director called in GPRS, Kauffman, a Leak Detection specialist who is certified in Subsurface Investigation Methodology at the 201 level, began creating an exhaustive map of the subsurface water system as he deployed acoustic technology and leak correlators, along with ground penetrating radar (GPR) and electromagnetic (EM) locators to find and document the water infrastructure.

“Locating a leak on this line was going to be very, very difficult,” Kauffman remembered. He could hear something outside the facility, but it was too faint to be the sizable leak he knew he was after, so he called on back-up: Steve Carney, a GPRS Leak Detection Area Manager in New York. Because of our nationwide footprint and collaborative approach to problem solving, Carney was able to advise him that the leak was likely coming from inside the building.

And, sure enough, once Kauffman got permission to enter the building and listen, he pinpointed the leak to an elbow joint right at the point the pipes entered the building.

“It almost blew my ear drums out, it was so loud,” Kauffman said.

Once he pinpointed the leak, he provided his customer with a full Leak Detection Report, detailing the leak location, the steps taken to confirm its location, and a PDF map of the water line system, all delivered via SiteMap®, so that every member of the facility team who needed the information could access it at the click of a button.

How Water Loss Surveys Save Facilities Money

The big question Kauffman is left with is whether the customer confirmed where the water ran off to. Utility lines of all kinds provide what are called preferential pathways: migration paths for liquids to move more quickly along the utility line channels than through packed soil, which can be a particular problem for mitigating NRW.  

That’s why annual routine water loss surveys are strongly recommended for facilities and municipalities of all sizes; because you can’t stop what you can’t find. Every big leak starts as a small one, and it is much easier to repair a small leak than deal with the damages that can be caused by a large one.

“When you’re losing that much water, at that volume, and there’s no evidence of it surfacing anywhere, it was believed that it was most likely under the building… This particular facility had a two-foot thick, slab-on-grade foundation,” said Kauffman.

Frequently Asked Questions

How Can I Stop Non-Revenue Water Loss?

Routine leak detection surveys are a start, but education of your team is crucial to mitigate leak problems before they become catastrophes. GPRS sponsors Water & Sewer Damage Awareness Week (WSDAW) each fall to educate facility and municipal managers on how they can stop NRW loss and save money.

How does Acoustic Leak Detection Work?

Acoustic leak detection is almost more art than science, which is why the best-trained GPRS Project Managers have years of experience and have built a sound library – a reference full of the differing tones of water pressure, leaks, and ambient noise, catalogued by pipe material and diameter. It’s also why they never rely on their ears alone. Even if they are certain of their findings, our Project Managers back up their ears with the hard science of leak correlators. These machines utilize computer technology and algorithms to pinpoint leaks. They also allow us to provide reporting to customers about the variety and location of any leaks we find as part of a Leak Detection Report or Routine Water Loss Survey.

Leica Laser Scanners Offer These Advantages:

1. Unsurpassed scan speed and image capture: The Leica RTC360 scans at two million points per second and captures a full-dome HDR image in one minute. This means you can complete a full high-resolution scan of your project in less than three minutes with true HDR imagery. Running the scanner at maximum speed without HDR images allows you to complete scans in less than 30 seconds.
2. High data quality of the scans: The point cloud from Leica laser scanners is complete, clean, and crisp with no invalid points “floating” in the scan data.
3. Geometric accuracy: The geometry of scanned objects will be correct, other laser scanners return rounded edges.
4. Low range noise: Leica laser scanners achieve clean, high-quality scan data with low range noise at a high scan speed. Other laser scanners require scanning at a lower speed to obtain low range noise.
5. Mixed pixel filtration: Leica laser scan data is well filtered. The scanner’s on-board and import algorithms are highly intelligent. For example, rain and snow noise is now recognized as noise and is disregarded during the collection and import process using mixed pixel filtration.
6. HDR photo quality images: HDR photography involves taking multiple images at different exposures and combining them into a single image with greater dynamic range – that is, capturing detail both in the shadows and in the bright. Images that are too dark or too light can obscure important scene details.
7. Survey-grade dual-axis compensation: Real time liquid filled dual axis compensation helps mitigate movement and ensure level scans.
8. Superb data management: High-speed, high-quality laser scanning gives you the ability to capture a lot of data very quickly. Leica laser scanners store hundreds of gigabytes of data and transfer hundreds of megabytes of data per second. Other scanners rely on an open-format SD card to store and transfer this data and will quickly max out on storage space.
9. In-field pre-registration: Leica offers an in-field pre-registration system that integrates software with hardware to optimize efficiency.

As the popularity of 3D laser scan technology has accelerated, so has the expansion of scanner types and brands. Clients expect their site to be documented quickly and accurately and with Leica we can do that.

Are you using 3D laser scanning on your construction projects?

Every construction professional would benefit from learning the advantages of 3D laser scanning buildings or construction sites. Many construction projects lack current records or as-built drawings. This information is critical for construction planning because it helps engineers to expedite design planning using the real-world building data as a foundation.

Understanding how 3D laser scanning can benefit your construction business is an important step in improving overall efficiency and profitability, whether you’re embarking on a new build, a renovation, or facility maintenance. As built laser scanning allows you to gather accurate, detailed information about existing site conditions. Data is collected in a point cloud, a database of millions of x, y, and z data points in a 3D coordinate system. Accurate to within 2mm-4mm, this is a precise digital record of a building or site.

‍

‍

The History of 3D Laser Scanning in Construction

3D laser scanning technology was created in the 1960’s. The early scanners used lights, cameras and projectors. Due to limitations of the equipment, it often took a lot of time and effort to scan objects accurately. In the 1980’s, LiDAR scanners for construction captured three-dimensional data points from existing architecture. In the 1990’s, 3D laser scanning began being utilized for design and engineering purposes. CAD software allows engineers to convert the point cloud to 2D drawings and 3D models.

‍

How is Laser Scanning Used in Construction?

How is laser scanning used in construction today? Originally, a 3D laser scanning survey was used in the construction and maintenance of industrial plant facilities. Laser scanning has since been adopted for many other uses, including design, construction, renovations and so much more.

• Design: Laser scanning is the best way to begin design planning. Construction engineers can utilize a scan-to-BIM method to capture detailed site information. Building Information Modeling (BIM) gives engineers, architects and contractors the opportunity to design the details of a building virtually. It accelerates design planning and reduces miscalculations, change orders and material waste. Buildings that begin with BIM are often built with great efficiency
• Construction: Laser scanning provides advantages for construction coordination, specifically in avoiding conflicts between different systems, such as HVAC, electrical, and plumbing. Data can be shared to help with remote coordination. 3D building scanning services aren’t just performed at the beginning of a project either; they can be done at various other points along the timeline to better document construction progress, reduce change orders and share work to other trade professionals. Laser scanning in construction can also document errors and identify a faster solution. 3D laser scanning expedites prefabrication by documenting existing structural elements to plan for modifications
• Renovations, Operations and Retrofits: 3D building scanners capture a very high level of detail, and this helps create a permanent as-built record for both owners and facility managers. This data can help with building operations, modifications, renovations and future building additions

‍

Building Information Modeling (BIM) is an intelligent 3D model that gives architecture, engineering, and construction (AEC) professionals the insight and tools to more efficiently plan, design, construct and manage buildings and infrastructure. BIM models give engineers data to manage the building throughout its entire lifecycle. It provides accurate geometry and spatial relationships, as well as documents specific building features.

‍

‍

5 Unique Benefits of BIM

‍

3D BIM modeling has been used in construction and other industries to better understand and organize the entire scope of a project. Here’s how BIM helps construction projects run as smoothly as possible:

‍

Increased Productivity

BIM gives engineers, architects and contractors the opportunity to design the details of a building virtually. It expedites design planning and reduces miscalculations, building faults and material waste. As a result, buildings that begin with BIM are often built with great efficiency and better productivity. An improved workflow helps to speed up the project.

‍

Effective Cost Estimation

Using 3D BIM modeling in conjunction with cost-estimating technology can lead to more accurate estimates. In the early stages of building planning, construction firms can leverage automation technologies to cut down on the time spent calculating costs for each part of the project. Using the dimensions of the BIM model they can quickly estimate the amount of material and costs needed.

‍

Foreseeing Potential Issues

One of the greatest benefits of BIM modeling is that it can be used to factor in risks and potential problems that may arise during the building stage. Before construction even begins, scan to BIM helps contractors identify internal and external clashes, and work to correct and prevent these. In this way, BIM technology reduces the need for rebuilding, which in turn increases project efficiency and reduces the costs associated with rework. At the same time, it creates safer, more predictable working environments for those on the building site.

‍

Better Building Quality

With more productivity, cost reduction and fewer faults, BIM leads to better buildings. Team members are better able to coordinate with each other on project details, and contractors can rely on a coordinated model that helps to mitigate risks. Thus, BIM is a crucial part of ensuring exceptional building quality.

‍

Better Marketing

For the construction industry, BIM goes much further than the buildings themselves. Existing BIM models can be used to market the kind of work that a construction company does. By using these models as part of the company’s marketing, business owners can show potential clients how they can benefit from the company’s technologies. While this is not one of scan to BIM’s biggest benefits, it’s important to know that it can help make an impressive proposal.

‍

Accurate Site Data for Better Decision Making

The construction industry has come a long way. The manual, tedious, and often inaccurate process of creating as-builts has been replaced with state-of-the-art technologies that deliver accurate site data for better decision-making. This technological breakthrough is 3D laser scanning, often referred to as reality capture or digital twin technology.

‍

What is Reality Capture?

Reality capture produces a digital 3D model representation of a building or site after scanning it in the real world using long-range 3D terrestrial laser scanners. Using laser scanning or photogrammetry methods, millions of surface points are measured and mapped to develop a high-resolution, geometrically precise 3D model. The result is a complete and accurate set of real-time data, which can be directly connected into design and visualization software.

‍

3 Steps for Reality Capture

1. Capture

3D laser scanners use LiDAR technology to capture millions of data points of a project site. Scans are taken in multiple positions from varying viewpoints and processed into a point cloud.

2. Process

From there, engineers register and clean the point cloud, and stitch it into a coordinate system to provide the most precise measurements.

3. Model

Using BIM and CAD software 3D models are created from the actual site conditions. Engineers can design with confidence knowing the information is accurate.

‍

What are the Benefits of Reality Capture?

Removes guesswork

Reality capture via 3D laser scanning captures incredible site detail. Each point is captured and mapped onto an XYZ coordinate system for an intelligent survey output to remove any guesswork from decision making.

It’s more than a documentation process

Reality capture transforms every point of the construction site into usable data. However, it doesn't stop there. Reality capture software offers cloud-connected tools to create a collaborative and interactive environment, allowing everyone to pitch in and do more with the captured data.

Less trips to the jobsite

There is no need to take return trips to the construction site because of missed measurements. A 3D digitized replica, or digital twin, offers design and construction teams more time to design instead of spending time on doing tedious manual data capture.

3D laser scan technology can be applied in exciting new ways. This is especially true within the entertainment industry. Here are a few examples of Mixed Reality (MR) fan experiences only made possible by GPRS’ 3D laser scans, point clouds, 3D meshes, and BIM models:

‍

‍

Gillette Stadium Mixed Reality Video Campaign

On October 24, 2022, under the Monday Night Lights of the Chicago Bears vs. New England Patriots football game at Gillette Stadium, a virtual reality video campaign aired promoting the Gillette Exfoliating Bar Razor.

In this powerful scene, the Patriot’s mascot enters the locker room and flips the Gillette Labs switch, initiating an augmented reality sequence out on the field. This segment featured the assembly of a giant razor floating over the field and a grand finale of fireworks.

‍

‍

This is the first time ever in which a retail product has been brought to life in this way using mixed reality software.

It was GPRS’ 3D laser scanning capabilities which provided a full 3D model of the entire stadium for The Famous Group to then use for the perfect placement of their virtual designs.

The Famous Group EVP/Business Development’s Andrew Isaacson stated that the laser scan data provided The Famous Group with “pinpoint accuracy of the location of existing architecture," which The Famous Group then used their “mixed reality effects to make it come to life."

‍

‍

Bank of America Stadium’s Carolina Panther

‍If you visit The Famous Group’s home page, the first video you see features a massive panther leaping down from the top of the Bank of America Stadium’s scoreboard during a Carolina Panthers game in Charlotte, North Carolina.

It took only 1.5 days onsite to fully scan Bank of America Stadium with a Leica P40 ScanStation and bring this now-famous video to life. This efficient, time-saving scanning process provided a hyper-accurate backdrop for this incredible mixed reality mascot.

In addition to the stadium, we also fully scanned and modeled Todd Andrew’s “Gentle Giant” sculpture of the fierce panther which has guarded the stadium gates for years. Our digital model was then used to bring this iconic statue to life both on TV during the NFL’s broadcast of the game and on the stadium’s Jumbotron.

‍

‍

M&T Bank Stadium’s Baltimore Raven

‍As with the work we provided for the Carolina Panther video, GPRS’ laser scanning capabilities supported The Famous Group in the design of a mixed reality raven which was featured during a recent Baltimore Ravens home game. This giant, menacing raven perches on the goal post before taking flight across M&T Bank Stadium’s field in Baltimore, Maryland.

This project presented its own challenges, especially in the design of the raven perched on the goal post and its overall visibility against the night sky.

When interviewed about the project, The Famous Group’s Greg Harvey said, “The beauty of mixed reality is the ability of computer-generated objects to interact with the physical environment, this sells the realism.”

To achieve this hyper-realistic experience for viewers, it was crucial that “parts of the stadium were captured with a laser-scanning technique,” so that, “when the bird is actually on the uprights, its claws wrap around the crossbar and its wings appear behind the uprights.”

These fine details are only made possible through the accuracy of 3D laser scan technology.

‍

‍

The Technology of 3D Laser Scanning

3D laser scanning is an innovative, modern, and efficient tool for mapping and modeling a variety of projects.

Leak detection correlators are sophisticated devices used to precisely locate leaks in water lines. They work by measuring the time delay of sound waves generated by a leak as they travel to sensors placed at different points along the pipe.

How Leak Detection Correlators Work

1. Sensor Placement: Sensors are positioned at multiple locations along the suspected leak area

2. Sound Wave Analysis: The correlator measures the time it takes for sound waves to travel from the leak to each sensor

3. Leak Location: By analyzing the time delay and the speed of sound in the pipe material, the correlator calculates the exact location of the leak

Pros:

• Highly accurate in pinpointing leak locations
• Effective for various pipe materials and sizes
• Can be used over long distances

Cons:

• Requires skilled operators to set up and analyze results
• May be less effective in very noisy environments
• Best Practices for Locating Water Lines

Post tension cables are a critical component in modern construction, offering enhanced strength and flexibility to concrete structures.

This technology allows engineers to build longer spans, thinner slabs, and more complex designs than would be possible with traditional reinforced concrete.

What are Post Tension Cables?

Post tension cables, also known as tendons, are steel cables that are used to reinforce concrete. Unlike traditional rebar, which is embedded in concrete before it hardens, post tension cables are tensioned (tightened) after the concrete has been cast and has gained sufficient strength. This process imparts a compressive force (a physical force pressing inward on an object, causing it to be compacted) to the concrete, counteracting the tensile (stretching) forces that the structure will experience during use.

The Mechanics of Post Tensioning

Pre-Tensioning vs. Post-Tensioning

To understand post-tensioning, it's essential to distinguish it from pre-tensioning. In pre-tensioning, steel tendons are tensioned before the concrete is poured. The tension is released after the concrete has set, transferring the compressive force to the concrete. This method is commonly used in precast concrete products, such as beams and slabs.

In post-tensioning, the steel cables are placed within ducts or sleeves in the concrete formwork. After the concrete has cured and achieved a specified strength, the cables are tensioned using hydraulic jacks and then anchored in place. This technique allows for on-site application and greater flexibility in design and construction.

The Post-Tensioning Process

1. Design and Planning: Engineers design the post-tensioning system based on the structural requirements of the project. This includes determining the number, placement, and tensioning force of the cables.

2. Placement of Cables: Steel cables, encased in plastic or metal ducts, are arranged within the concrete formwork according to the design specifications. These ducts are often curved to follow the optimal stress paths within the concrete.

3. Concrete Pouring: Concrete is poured into the formwork, encapsulating the ducts and cables. Care is taken to ensure that the concrete is well-compacted and that the ducts are properly positioned.

4. Curing: The concrete is allowed to cure and gain sufficient strength, typically over a period of several days to weeks, depending on the project specifications and environmental conditions.

5. Tensioning: Hydraulic jacks are used to tension the cables. The jacks pull the cables to the required force, stretching them within the ducts. This process imparts a compressive force to the surrounding concrete.

6. Anchoring: Once the desired tension is achieved, the cables are anchored at both ends using specialized hardware. The anchors hold the cables in place, maintaining the compressive force within the concrete.

7. Grouting (optional): In some cases, the ducts are filled with grout to protect the cables from corrosion and to improve the bond between the cables and the concrete.

Why Contractors Use Post Tension Cables

Increased Load Capacity

Post tension cables significantly enhance the load-bearing capacity of concrete structures. The compressive force introduced by the tensioned cables counteracts tensile stresses, reducing the likelihood of cracking and increasing the overall strength of the structure.

Design Flexibility

Post-tensioning allows for greater design flexibility compared to traditional reinforced concrete. Engineers can create longer spans, thinner slabs, and more intricate shapes, making it possible to achieve architectural designs that would be challenging or impossible with conventional methods.

Material Efficiency

The use of post tension cables can reduce the amount of concrete and steel required for a given project. Thinner slabs and longer spans mean less material is needed, leading to cost savings and a smaller environmental footprint.

Reduced Maintenance

Structures reinforced with post tension cables tend to have fewer cracks and require less maintenance over their lifespan. The compressive force helps to keep the concrete in compression, reducing the risk of damage from tensile stresses.

Applications of Post Tension Cables

Bridges and Overpasses

Post-tensioning is widely used in the construction of bridges and overpasses, where long spans and high load capacities are essential. The technique allows for the creation of slender, elegant structures that can withstand heavy traffic loads and harsh environmental conditions.

High-Rise Buildings

In high-rise construction, post-tension cables enable the creation of thinner floor slabs and longer spans between columns. This reduces the overall weight of the building and allows for more flexible interior layouts.

Parking Structures

Parking structures benefit from post-tensioning due to the need for long, column-free spans and durable, crack-resistant surfaces. The technique helps to maximize usable space and extend the lifespan of the structure.

Industrial Floors and Slabs

Post-tensioning is also used in the construction of large industrial floors and slabs, where heavy loads and minimal cracking are crucial. The technique provides a durable, high-performance surface capable of withstanding the demands of industrial operations.

Post Tension Cable Limitations

While post-tensioning offers many advantages, it also presents some challenges and considerations. Proper design and installation are critical to ensure the success of a post-tensioning system. Engineers and contractors must be trained and experienced in post-tensioning techniques to avoid issues such as improper tensioning, duct alignment problems, or inadequate anchoring.

Additionally, post-tensioned structures require careful inspection and maintenance to ensure the integrity of the cables and anchors over time. Corrosion protection, regular inspections, and timely repairs are essential to maintaining the long-term performance of post-tensioned systems.

Post tension cables have revolutionized the field of construction, offering enhanced strength, flexibility, and efficiency to concrete structures. By understanding the mechanics of post-tensioning and its benefits, engineers and builders can leverage this technology to create innovative and resilient designs. As the construction industry continues to evolve, post-tensioning will remain a vital technique for meeting the demands of modern infrastructure projects.

Frequently Asked Questions

How is Ground Penetrating Radar Used to Identify Tendons vs. Rebar in a Post-Tensioned Slab?

In post-tensioned structures, we typically find one mat of support rebar near the base of the slab. This mat is generally consistently spaced and remains at a constant elevation. Post-tension cables are generally found above this support mat and “draped” throughout the rest of the structure. The elevation of the cable is usually high near the beams and column lines and drapes lower through the span between beams and column lines. Knowledge of these structural differences allows us to accurately differentiate between components. Our Project Managers will leave you feeling confident in our findings and in your ability to drill or cut without issue.

Can Ground Penetrating Radar the Difference Between Rebar and Electrical Conduit?

Ground penetrating radar (GPR) can accurately differentiate between rebar and electrical conduit in most cases. We have an extremely high success rate in identifying electrical lines in supported slabs or slabs-on-grade before saw cutting or core drilling.

Additionally, GPRS can use electromagnetic (EM) locators to determine the location of conduits in the concrete. If we can transmit a signal onto the metal conduit, we can locate it with pinpoint accuracy. We can also find the conduit passively if a live electrical current runs through it.

The combined use of GPR and EM induction allows us to provide one of the most comprehensive and accurate conduits locating services available.

The process of locating buried utilities has come a long way from its rudimentary beginnings.

Advanced technologies like ground penetrating radar (GPR) and electromagnetic (EM) locating have revolutionized the field, ensuring safer and more efficient excavation practices. The historical evolution of utility locating, the advancements in technology, and the role of professional utility locating companies in modern infrastructure projects is fascinating.

The Emergence of 811 and Regulatory Frameworks

In the early days, locating buried utilities was largely a trial-and-error process. Workers relied on rudimentary tools and manual digging, often leading to accidental damage to underground infrastructure. Maps and records, if available, were frequently outdated or inaccurate, resulting in significant risks during excavation.

The establishment of the 811 service marked a significant milestone in the field of utility locating. Introduced in the United States, 811, also known as One Call, is a nationwide number that individuals and contractors can call before digging to ensure that buried utilities are properly marked. This service has been pivotal in reducing the incidence of utility strikes, promoting safety, and protecting critical infrastructure.

Technological Advancements in Utility Locating

Ground Penetrating Radar (GPR)

Ground Penetrating Radar (GPR) is one of the most significant advancements in utility locating technology. GPR uses radar pulses to create images of subsurface structures. It can detect non-metallic and metallic utilities, making it a versatile tool in the locator's arsenal.

The technology works by transmitting high-frequency radio waves into the ground. When these waves encounter a buried object or different material, they bounce back to the surface, where they are captured by a receiver. This data is then processed to generate a visual representation of the subsurface environment. GPR is particularly useful in detecting utilities like plastic pipes, which are not detectable by traditional EM locating methods.

Electromagnetic (EM) Locating

Electromagnetic (EM) locating is another cornerstone of modern utility locating practices. EM locators operate by transmitting a signal into the ground and detecting the electromagnetic fields generated by underground metallic utilities. This method is highly effective for locating pipes, cables, and other conductive materials.

EM locating has seen significant advancements over the years. Modern EM locators are more sensitive and capable of providing more accurate readings. They can differentiate between multiple utilities and provide depth estimates, aiding in precise excavation planning.

The Role of Professional Utility Locating Companies

As utility locating technologies have advanced, the role of professional utility locating companies has become increasingly important. These companies employ trained and certified technicians who are skilled in using GPR, EM locating, and other advanced methods. Their expertise ensures that utilities are accurately located and marked, minimizing the risk of damage during excavation.

Professional utility locating companies also provide comprehensive services that go beyond mere locating. They offer utility mapping, data management, and consultation services, helping project managers and contractors make informed decisions. By leveraging the latest technologies and best practices, these companies play a crucial role in maintaining the integrity of underground infrastructure.

Integrating Technology and Data Management

The integration of technology and data management has further enhanced the field of utility locating. Modern locators are equipped with GPS and GIS capabilities, allowing for precise mapping and documentation of utility locations. This data can be stored and accessed digitally, ensuring that records are up-to-date and easily retrievable for future projects.

Additionally, the use of mobile apps and cloud-based platforms has streamlined communication and coordination between utility locators, contractors, and project managers. These tools facilitate real-time data sharing, enabling more efficient and collaborative workflows.

Safety and Regulatory Compliance

Safety is a paramount concern in utility locating, and technological advancements have significantly improved safety outcomes. GPR and EM locating technologies reduce the likelihood of accidental utility strikes, protecting workers and preventing service disruptions.

Regulatory compliance is also a critical aspect of utility locating. Professional utility locating companies adhere to strict industry standards and guidelines to ensure that their practices meet legal and safety requirements. By following established protocols and leveraging advanced technologies, these companies help mitigate risks and ensure the success of excavation projects.

The Future of Utility Locating

The field of utility locating continues to evolve, driven by ongoing technological innovations and increasing demand for infrastructure development. Emerging technologies like artificial intelligence (AI) and machine learning are poised to further enhance the accuracy and efficiency of utility locating.

AI-powered systems can analyze vast amounts of data to identify patterns and anomalies, improving the detection and mapping of buried utilities. Machine learning algorithms can optimize locating processes by continuously learning from previous projects and refining techniques.

97.5% of the earth’s water is seawater, unsuitable for human consumption. With growing populations and rising temperatures, our freshwater resources are under significant threat.

Global water demand is projected to rise by 55% between 2000 and 2050. Agriculture, which accounts for 70% of global freshwater use, drives much of this demand. Additionally, food production must increase by 69% by 2035 to meet the needs of the expanding population. Water is also crucial for energy production, such as cooling power stations, with this demand expected to grow by over 20%. The future presents a significant challenge, and we need solutions quickly.

A NASA-led study indicates that the earth’s freshwater resources are being depleted faster than they are being replenished. While leaky pipes in your home or underground might seem insignificant, they contribute to a massive, unsustainable loss when the planet is potentially running out of water.

Tackling this issue requires innovative solutions beyond conventional methods. Advanced models for municipal leak reduction are emerging as vital, offering precision, efficiency, and sustainability to combat non-revenue water (NRW) loss. What are these innovations? What impact do they have? What transformative potential do they hold for communities worldwide?

Could this technology help save the world?

Understanding the Challenge

Before exploring solutions, it's vital to understand the scope of the problem. Globally, water infrastructure is constantly threatened by leaks. According to the American Water Works Association, the United States experiences an estimated 240,000 water main breaks annually, wasting over 2 trillion gallons of treated drinking water. The situation is equally dire worldwide.

Non-revenue water (NRW) loss from preventable leaks also strains municipal budgets. Repairing infrastructure damage, treating additional water, and managing environmental impacts significantly drain financial resources. Moreover, leaks undermine water system reliability, jeopardizing access for communities.

Our water resources are dwindling. Of the world’s major aquifers, 21 out of 37 are receding, affecting regions from India and China to the United States and France. The Ganges Basin in India, for instance, depletes by an estimated 2.4 inches annually due to population and irrigation demands. NASA's senior water scientist Jay Famiglietti warns, “the water table is dropping all over the world. There’s not an infinite supply of water.”

Mexico City is sinking in some areas at a rate of nine inches per year due to underground leaks. Drawing from its aquifer creates an effect similar to drinking a milkshake through a straw, causing once-level streets to undulate like rollercoaster tracks. The city now imports 40% of its water to sustain its communities.

California also faces significant water-security challenges. From 2011 to 2016, the state endured its worst recorded drought in 1,200 years, with roughly 1,900 wells running dry. Relief came, but with a vengeance. In the first three months of 2017, rainfall was 228% above normal levels. Lake Oroville, for example, surged from 41% to 101% of capacity in two months, overwhelming dams and prompting the evacuation of 188,000 residents.

The issue of NRW is universal, impacting communities large and small. Each day, 14 to 18 percent of treated water is lost — enough to serve 15 million homes. The problem is worsening. A 2018 study from Utah State University found pipe breaks in the U.S. and Canada increased by 27% over six years. Despite high water bills, customer payments aren’t sufficient to fund infrastructure repairs. The American Water Works Association estimates a $1 trillion price tag to fix this infrastructure crisis. Globally, the situation is even more dire. The World Bank estimates 35% of water in distribution systems is lost across 44 countries, totaling around $14 billion in lost water annually.

Small leaks, which lose less than 10 gallons per minute, aren’t even classified as leaks by the ASCE and aren’t included in the 240,000 annual break estimate. These “potential leaks” become leaks, and leaks become breaks, resulting in millions of gallons—and dollars—lost.

The ongoing dehydration of the world due to leaks is a significant issue, but it’s not without solutions. Technologies like those used by SiteMap^® (patent pending), powered by GPRS, are proving to be critical in addressing this leaky puzzle, benefiting both small towns and big cities.

Advanced Models For Advanced Issues

To overcome the limitations of traditional NRW retrieval methods, many water managers are turning to advanced models powered by cutting-edge technology, such as the technology that is used by GPRS daily. Next-generation technologies for water conservation and leak detection aim to reduce waste and promote efficient use of water. These include advanced leak detection systems that utilize artificial intelligence and machine learning to identify and locate leaks, ensuring quick mitigation.

1. Data Analytics

Advanced data analytics algorithms analyze historical usage data, pressure readings, and geographical information to identify patterns indicative of leaks. By integrating diverse datasets, these models can pinpoint potential leak locations with remarkable accuracy, enabling proactive leak detection and repair.

2. Sensor Networks

Advancements in sensor technology have facilitated the deployment of robust sensor networks across water infrastructure. These sensors monitor various parameters such as pressure, temperature, and flow, providing valuable data for analysis. By strategically placing sensors along pipelines, municipalities can detect leaks promptly and accurately, enabling timely response and mitigation.

3. Other Methods and Examples

There are plenty of unique methods being used worldwide to help reduce the drain of our important water resources. Some are only able to operate effectively with the help of ground penetrating radar and other complementary technologies, as some require an initial understanding of the location before the new technology can be placed.

AQUAKIT SRL (from Bolivia) is a greywater treatment system meant for large-scale residential and commercial buildings. This system can reclaim up to 300,000 liters per month from a single 12-story building. By recycling greywater for non-potable purposes, like toilet filling, irrigation, and cleaning, AQUAKIT drastically reduces water consumption while also minimizing wastewater emissions.

As many would guess, Australia is hot and dry, and is also struggling to keep water stores high. Australia’s Bureau of Meteorology estimates that nation-wide average non-revenue water losses are sitting somewhere around 10%. Granted, this figure is low compared to other places around the world. However, if the figure was reduced to even just 6%, it would result in Australia sowing an energy savings of 10%. To help fight water loss, Australia has come up with a unique solution: leak sniffer dogs.

When managing chlorine levels in tap water reaching up to four parts per million, the mighty nose of a sniffer dog has no problem sorting the leaks out from puddles. These innovative and powerful noses can detect one particle of an odor or scent in a billion!

Digital twins also play a vital role in NRW reclamation. They are important virtual representations of a real-world object or system. They are so useful that they have been gaining traction in the tech community for their ability to use real-time data in their modeling, enabling experimentation with larger objects. SmartTerra of India is deploying digital twin technology in their water networks to reduce water losses. They have also found that digital twins not only help reduce water losses, but they also help to enhance revenue streams. Our talented Mapping and Modeling Team can create digital twins (and detailed as builts) just like the ones being used to preserve India’s water sources.

The agricultural industry, responsible for 70% of global freshwater withdrawals, is the biggest drain on our current water supply. SEABEX in France is using digital twin technology to allow precision irrigation to go sensor-less. Driven by AI algorithms, this unique technology enhances crop yields and allows farmers to reduce water waste by up to an amazing 50%.

4. Inspections and Combination Methods

Annual inspections, known as water loss surveys, may utilize some more traditional leak detection methods, but they are one of the most reliable ways to detect pressurized water line leaks. These inspections are made even better when the data is represented in an easy to understand platform, annotated and aggregated on searchable and customizable maps. GPRS VPI and leak detection services enhance a utility locate or full-site scan because they not only find the pipes, our Project Managers deploy robotic sewer scope cameras, push cameras, lateral launch cameras, and additional technologies to inspect them, document their existing conditions in an interactive, NASSCO-certified report, and include them in a comprehensive, layered utility map, delivered digitally via SiteMap^® for your use, 24/7.

GPRS strongly recommends sanitary and storm sewer system inspections every other year to update your existing condition documentation, find new breaks, cross bores, and defects, and protect your system, facility, and community.

GPRS Intelligently Visualizes The Built World^® through utility locating, concrete scanning, 3D laser scanning, and leak detection, which can all complement our NASSCO-certified VPI reporting to provide you with accurate as-builts of your entire infrastructure. Our in-house Mapping & Modeling Team can take it a step further, we can integrate your existing as-builts and even proposed changes to assure accurate measurements and locations of existing assets, to save you time and money. With GPRS, neither your water, nor your income will dry up.

Impact and Benefits

The adoption of advanced models and new technologies for  leak reduction yields a myriad of benefits, both tangible and intangible. The United Nations Educational, Scientific and Cultural Organization (UNESCO) estimates that 2 billion people just don’t have access to safe drinking water with 3.6 billion lacking access to safely-managed sanitation.

Through technology and science, the same type that is used every single day by our elite Project Managers at GPRS, societies can monitor and preserve our precious water sources, preventing leaks and securing resources for the future. There are many benefits when it comes to the preservation of water and leak reduction, including:

1. Conservation of Resources

By minimizing water loss, municipalities conserve a precious resource and ensure sustainable water management. This not only benefits the environment but also enhances water security for communities. Conservation is crucial, as according to the United Nations, over 40% of the global population currently experiences water shortages, and this figure is expected to grow. What's worse, less than 3% of the world’s water supply is freshwater that is suitable and accessible for human use. By conserving water as much as possible, we’re ensuring that billions of people worldwide have access to proper drinking water for years to come.

2. Cost Savings

Efficient leak detection and management translate into significant cost savings for municipalities. By addressing leaks promptly and accurately, infrastructure damage is minimized, reducing repair costs and operational expenses. GPRS is skilled at finding leaks before they start to also drain your wallet.

GPRS has had many satisfied clients like the one discussed above. The client, a municipality in New York, was experiencing a significant amount of NRW loss due to leaks along their 110-mile system. Utilizing acoustic leak detection, and leak detection correlators, the GPRS Project Manager evaluated the entire system including hydrants, in-line main valves, and service valves.

The findings were stark: 18 leaks, four of which were costing the town over 10,000 gallons per day each in NRW loss. After GPRS, New Castle saved an estimated 125,000 gallons per day (GPD) after resolving the detected leaks. They were also able to dig only where they needed to rather than excavating large segments of the water system to inspect for leaks, and experienced improved service performance and reduced risk of service interruptions. There are 2.2 million miles of water lines in the U.S., and GPRS is here to help with every inch of them, saving you money, and most importantly, saving you water.

3. Improved Service Reliability

Whether you’re a facility manager, general contractor, or a municipality, by proactively addressing leaks, you’re able to enhance the reliability and resilience of water systems. This ensures uninterrupted water supply for residents and businesses, fostering community trust and satisfaction. GPRS strives to take it a step further. By having your Project Manager flag and paint their findings directly on the surface, you and your team know where it is and is not safe to dig. GPRS also uses a global positioning system (GPS) to collect data points of findings used to generate the maps and models you need to Intelligently Visualize The Built World®. Water is a basic need for life of all types, service interruptions can lead to serious consequences, especially when so many of them are preventable by maintaining a proper schedule of inspection and maintenance.

4. Environmental Impact

We may not like to hear it, but water is a finite resource, and it’s becoming harder to retain much of our water stores. With most of the water on earth being non safe for human consumption, it becomes even more crucial that conservation efforts are accelerated. Reducing water loss through leaks has a positive environmental impact and mitigating leaks minimizes the risk of contamination and environmental damage.

The Road Ahead

From leak detecting robots to GPRS leak detection correlators, there are more and more ways to detect leaks and save water. As municipalities continue to grapple with aging infrastructure and increasing water challenges, the need for advanced models for leak reduction becomes increasingly pressing. Embracing innovation and harnessing the power of data analytics, among other technologies, is a crucial step in the road ahead.

By merging innovative technologies and trusted classics, GPRS can perform routine Water Loss Surveys to update your existing condition documentation, find new defects and leaks to better maintain your system, protect your water, and your community.

Cities all around the world are turning to technology for more efficient and effective water management. Many cities are utilizing smart technologies like IoT (Internet of Things) sensors and AI (Artificial Intelligence.) These technologies are being used to monitor water quality, detect leaks, and manage water flow. These technologies allow for these processes to happen seamlessly, and quickly.

Places all over the world are adopting new technology to help answer this age-old water problem. The Singapore Public Utilities Board has implemented a smart water grid system that uses IoT technology to provide real-time monitoring and control of the water supply network,. This network then enables the immediate detection and repair of leaks.

Barcelona offers something similar with a smart irrigation system that uses weather forecasts and soil moisture data to optimize the watering of its public parks. This method has shown to reduce water consumption by 25%.

Through the approach of harnessing the power of technology, cities are able to take major strides towards water conservation, helping to ensure the sustainability and availability  of this precious resource for future generations.
