Understanding Non-Revenue Water Loss

Non-revenue water loss is a critical issue in water management. It encompasses any water that does not generate revenue, primarily due to:

Leaks: Unintended water escape from the distribution network, which can occur in pipes, joints, or valves
Theft: Unauthorized connections or tampering with the water supply
Metering Inaccuracies: Faulty meters that do not accurately record water usage

Leaks are the most common cause of non-revenue water loss, particularly those that are underground and hard to detect. Identifying and fixing these leaks not only conserves water but also improves the efficiency of water distribution systems.

Signs of an Underground Water Leak

Before diving into detection techniques, it's essential to recognize the signs indicating a potential underground water leak:

Unexplained Water Bills: Sudden increases in water bills without a corresponding increase in usage
Wet Spots or Water Puddles: Persistent wet areas in your yard or around your property, especially during dry weather
Decreased Water Pressure: Noticing a drop in water pressure, indicating a possible leak in the supply line
Sound of Running Water: Hearing water running when all taps are closed can be a sign of a hidden leak
Cracks in Foundation: Structural damage like cracks in walls or floors may be due to water eroding the foundation

Techniques for Locating Underground Water Leaks

Acoustic Leak Detection

Acoustic leak detection is a popular method that involves listening for the sound of water escaping from pipes. This technique relies on specialized equipment to detect the acoustic vibrations generated by leaks.

How It Works: As water leaks from a pipe, it creates a distinct noise. Acoustic leak detection devices, such as ground microphones and listening rods, amplify these sounds, allowing technicians to pinpoint the leak’s location.

Equipment Used:

Ground Microphones: These are sensitive devices placed on the ground surface to listen for leak sounds
Listening Rods: These are used to directly contact exposed pipes and listen for leak vibrations

Procedure:

Investigate: Technicians investigate the area with ground microphones to identify the general vicinity of the leak
Pinpoint: Using listening rods or more focused ground microphones, they narrow down the precise location

Advantages:

Non-Invasive: Does not require digging or disruption of the surface
Accurate: Can pinpoint the exact location of leaks with high precision

Leak Detection Correlators

Leak detection correlators are advanced devices that use the time difference in sound waves traveling through the pipe to locate leaks.

How They Work: Two or more sensors are placed at access points along the pipeline. These sensors detect the noise from the leak and send data to a central unit. The correlator calculates the leak’s position based on the time delay of the sound waves reaching each sensor.

Equipment Used:

Sensors: Placed on pipe fittings or access points to capture leak noise
Central Unit: Analyzes data from the sensors to determine the leak location

Procedure:

Placement: Sensors are strategically placed on the pipeline at known access points
Data Collection: The sensors transmit noise data to the central unit
Correlation: The central unit processes the data to calculate the leak’s location based on the difference in sound wave arrival times

Advantages:

Highly Effective: Particularly useful for long or complex pipeline systems
Real-Time Data: Provides immediate feedback on the leak location

Other Methods

While acoustic leak detection and leak detection correlators are prominent techniques, other methods also play a role in locating underground water leaks:

Ground Penetrating Radar (GPR)

How It Works: GPR sends radar pulses into the ground and measures the reflected signals to identify changes in the subsurface. This can detect buried pipelines and cavities caused by leaks.

Advantages: Useful for detecting leaks in non-metallic pipes and identifying subsurface anomalies.

Infrared Thermography

How It Works: Infrared cameras detect temperature variations on the surface caused by leaking water. Cold or warm spots can indicate the presence of water leaks.

Advantages: Non-invasive and effective for identifying leaks in heated or chilled water systems.

Locating an Underground Water Leak

Step 1: Confirm the Presence of a Leak

Before deploying advanced detection techniques, verify that a leak exists. Check your water meter for continuous movement when all water fixtures are off.

Step 2: Investigate the Area

Conduct a visual and acoustic evaluation of the suspected leak area. Look for visible signs and use ground microphones to listen for leak sounds.

Step 3: Use Advanced Detection Equipment

Deploy acoustic leak detection devices or leak detection correlators to pinpoint the leak’s location. Follow the specific procedures for each method to ensure accurate results.

Step 4: Validate and Repair

Once the leak is located, verify its position by minimal excavation or exposing the pipe. Proceed with the necessary repairs to fix the leak and restore the integrity of the water system.

Preventing Future Leaks

To minimize non-revenue water loss and prevent future leaks:

Regular Inspections: Schedule routine inspections and maintenance of your water distribution system
Pressure Management: Maintain optimal water pressure to reduce stress on pipes and fittings
Pipeline Monitoring: Use remote monitoring systems to detect early signs of leaks or pressure drops

How Different Soil Types Impact Excavation Projects

From the ease of digging in sandy soil to the challenges posed by dense clay, each soil type requires specific strategies and equipment to ensure a successful excavation.

Understanding soil conditions is crucial for any excavation project.

The type of soil you encounter can significantly influence your project's timeline, cost, and safety. From the ease of digging in sandy soil to the challenges posed by dense clay, each soil type requires specific strategies and equipment to ensure a successful excavation. This article explores how different soil types impact excavation projects and offers insights on how to manage them effectively.

The Big Three: Sand, Silt, and Clay

Soil is typically composed of a mix of sand, silt, and clay. Each of these soil types has unique characteristics that affect how they respond to excavation efforts.

Sand: The Easy Digger

Sand is composed of large, loose particles that create a soil type known for its excellent drainage and ease of excavation. This makes sand an ideal material for projects requiring quick and straightforward digging. Its properties allow for efficient drainage, which is beneficial for structures like basements and footings where water needs to move away from the foundation.

Advantages:

- Fast Drainage: Sand allows water to pass through quickly, reducing the risk of waterlogging and making it suitable for areas that need to stay dry.

- Ease of Digging: The loose particles of sand make it easy to excavate, often requiring less power and effort compared to other soil types.

- Reduced Equipment Wear: Since sand is less compact, it causes less wear and tear on excavation equipment.

Challenges:

- Stability Concerns: While easy to dig, sandy soil can be unstable, especially when dry. This can lead to cave-ins if proper shoring and support are not used.

- Erosion Risk: Sand can shift and erode easily under certain conditions, which might require additional stabilization measures.

Best Uses:

- Projects requiring quick excavation.

- Areas needing good drainage, such as basements and foundations.

- Applications where minimal erosion is a concern.

Silt: The Balancer

Silt is finer than sand but coarser than clay, and it can retain some moisture while providing moderate drainage. This soil type is often used in trench work and projects where a balance between stability and drainage is needed. Silt can hold water but also allows for gradual drainage, making it a versatile choice for many excavation projects.

Advantages:

- Moderate Stability: Silt is more stable than sand, providing a solid base for projects that require a reliable foundation.

- Good for Trenching: Its ability to retain moisture while draining gradually makes it suitable for laying pipes or electrical conduit.

- Adaptable for Various Projects: Silt’s properties allow it to be used in a variety of applications, from residential construction to utility work.

Challenges:

- Moisture Retention: Silt can become compacted and hold moisture, which may require special handling to avoid issues during excavation.

- Erosion Potential: While not as prone to erosion as sand, silt can still shift under certain conditions, requiring careful planning and management.

Best Uses:

- Projects that need moderate drainage and stability, such as trenches.

- Laying utility lines where a balance between stability and drainage is necessary.

- Areas where soil needs to be relatively stable yet adaptable.

Clay: The Tough Challenger

Clay consists of very fine particles that stick together, creating a dense and heavy soil type. Excavating clay is often challenging due to its stickiness and resistance. However, clay’s properties can be advantageous in projects that require a watertight seal, such as landfills or containment areas for hazardous materials.

Advantages:

- High Plasticity: Clay can be molded and shaped, making it useful for creating barriers and seals.

- Low Permeability: Its dense structure prevents water from passing through, ideal for projects requiring water containment.

- Durability: Clay provides a solid foundation for structures needing high stability and longevity.

Challenges:

- Difficult Excavation: The dense, sticky nature of clay makes it harder to dig through, often requiring more powerful equipment and longer project timelines.

- Expansion and Contraction: Clay can expand when wet and contract when dry, potentially leading to structural issues if not managed properly.

- Heavy Equipment Wear: The density of clay can cause significant wear on excavation tools and machinery.

Best Uses:

- Projects requiring a watertight seal, such as landfills or hazardous waste containment.

- Foundations where high stability is essential.

- Areas where soil movement needs to be minimized.

Managing Mixed Soils

Most excavation sites will encounter a mix of these soil types rather than pure sand, silt, or clay. Understanding the dominant soil type and its properties is key to planning and executing a successful excavation project. Here are some strategies to manage mixed soils effectively:

Soil Testing

Before starting any excavation, conducting thorough soil testing is crucial. This helps identify the soil composition and determine the best approach for excavation. Testing can reveal the proportions of sand, silt, and clay, guiding decisions on equipment and techniques.

Equipment Selection

Choosing the right equipment is essential for handling different soil types. For example, sandy soil might only need a standard excavator, while clay could require more powerful machinery and additional attachments to break through its dense structure.

Project Timeline and Budget

Understanding soil conditions can help estimate realistic project timelines and budgets. Excavating through clay, for instance, will likely take longer and cost more than digging through sand. Accurate estimates can prevent unexpected delays and cost overruns.

Safety Measures

Different soil types require specific safety measures to prevent accidents and ensure worker safety. Sandy or loose soil may need additional support to prevent cave-ins, while compacted clay could necessitate reinforced excavation walls.

Communication and Coordination

Effective communication among stakeholders is vital, especially in complex projects involving multiple soil types. Tools like GIS mapping programs can help project planners, utility owners, and field crews coordinate their efforts and share information about soil conditions and excavation progress.

Frequently Asked Questions

Can GPRS locate PVC piping and other non-conductive utilities?

GPR scanning is exceptionally effective at locating all types of subsurface materials. There are times when PVC pipes do not provide an adequate signal to GPR equipment and can’t be properly located by traditional methods. GPRS Project Managers, however, are expertly trained at multiple methods of utility locating.

Is GPRS able to distinguish between each type of underground utility which is located?

In most situations, we can identify the utility in question without any problems, although it is not always possible to determine what type of utility is present. When this happens, we attempt to trace the utility to a valve, meter, control box, or other signifying markers to determine the type of utility buried.

Will I need to mark out the utilities GPRS locates?

No, GPRS will locate and mark all utilities for you. We have a variety of tools and markers we can use to highlight the locations of utilities, underground storage tanks (USTs), and whatever else may be hiding.

GPRS Deploys ‘Super Sonde’ for Video Pipe Inspection

GPRS paired specialized equipment with our industry-leading sewer pipe inspection process to locate an old sewer line hidden 40’ below a 124-year-old college campus.

GPRS paired specialized equipment with our industry-leading sewer pipe inspection process to locate an old sewer line hidden 40 feet below a 124-year-old college campus.

GPRS Project Manager Nate Johnson was tasked with locating the pipe buried beneath Pittsburgh, Pennsylvania’s Carnegie Mellon University, where Costa Contracting was doing foundation work for a new building.

Green spray paint on the ground of a job site. — While existing as-built documentation for Carnegie Mellon University indicated a sewer line was running through the planned site for a new building, the contractor had been unable to accurately locate the line by themselves.

While existing as-built documentation for the university indicated a sewer line was running through the planned excavation site, the contractor had been unable to accurately locate the line by themselves.

This isn’t unusual; the average sewer line in the United States is 45 years old. Even today, many facilities don’t have accurate maps of their buried infrastructure.

This is a problem, especially considering that the average sewer line in the U.S. is also at 81% capacity and 70,000 sanitary sewer overflows occur annually. You can’t maintain what you can’t find.

To find the buried sewer line at Carnegie Mellon, Johnson inserted a remote-controlled sewer inspection rover into a nearby access point and piloted the device through the line running under the job site. All of GPRS’ rovers and push-fed sewer scopes are equipped with CCTV cameras and sondes: instrument probes that are detectable from the surface using electromagnetic (EM) locators. This allows us to map your sewer system at the same time we’re investigating it for defects such as cross bores and inflow/infiltration (I/I).

The problem was that our rovers’ internal sondes can only locate sewer pipes up to 15 feet into the Earth. Because of the hilly terrain found across much of western Pennsylvania, pipes are often buried much deeper than 15 feet.

A Prototek DuraSonde Transmitter on a table. — To find the sewer line, GPRS Project Manager Nate Johnson deployed this Prototek Durasonde Transmitter, which is locatable in nonmetallic pipes over 50’ in depth.

To overcome this challenge, Johnson equipped his rover with a Prototek DuraSonde Transmitter. Colloquially referred to as a ‘super sonde,’ this 10 ¼ inch-long, 8 KHz frequency transmitter is locatable in nonmetallic pipes over 50 feet in depth.

“So, it gets attached to the crawler and is able to be located with our EM locators...,” Johnson said. "We do [jobs with this device] from time to time. With how hilly it is in western Pennsylvania, some of the lines are quite deep.”

With the super sonde along for the ride, Johnson used the rover to conduct GPRS’ comprehensive Video Pipe Inspection services. Through this process, we provide our clients with NASSCO-certified, WinCan reports detailing all issues found within the pipes we locate and map. These reports include photo and video evidence of the defects, which are geolocated and ranked by severity, so you know where you need to dig to make repairs and can prioritize maintenance.

Even the best infrastructure data is useless if you can’t share it when and where it’s needed. That’s why GPRS created SiteMap^® (patent pending), a cloud-based infrastructure mapping software solution that provides accurate existing condition documentation to protect your assets and people.

Able to integrate with your existing GIS mapping system and securely accessible 24/7 from any computer, tablet or smartphone, SiteMap^® eliminates communication silos and the mistakes, reworks, and change orders they cause. With the field-verified data collected by GPRS’ nationwide team of Project Managers at your fingertips exactly when and where you need it, you can plan, design, manage, dig, and build better.

Johnson determined that the sewer line at Carnegie was a vitrified clay pipe. It’s a type of pipe he is intimately familiar with, having mapped most of the wastewater infrastructure in the City of Pittsburgh, which primarily consists of vitrified clay pipe.

Like clay pottery, vitrified clay pipe is hard to crush, but will snap when not properly supported or when placed under extreme pressure from an external source such as a tree root – or the foundation of a building built on top of it. Because Costa Contracting contacted GPRS to locate the pipe prior to laying the foundation for the building they were constructing, they ensured the safety and success of their project.

Where Do We Stand With The CGA’s 50 in 5 Initiative?

The Common Ground Alliance (CGA) made waves in February of 2023 when it unveiled its “50 in 5” initiative: a challenge to the damage prevention industry to reduce damages to critical underground utilities by 50% by 2028. While it’s still too early to truly gauge whether the initiative will be a success, the CGA is pleased with the response it has seen so far.

The Common Ground Alliance (CGA) made waves when it unveiled its “50 in 5” initiative in February 2023.

The national nonprofit dedicated to mitigating damage to buried utilities challenged the damage prevention industry to cut damages to critical underground utilities in half by 2028.

So far, the CGA is pleased with the results.

A woman smiling for the camera. — Sarah Magruder Lyle, President & CEO of Common Ground Alliance

“Once we announced 50 in 5, it basically took on a life of its own,” CGA President & CEO, Sarah Magruder Lyle, told the industry newsletter, The Built World*. “We have seen so many other associations and groups really grab that and say, ‘What can we do to do this?’ It’s gone from a, ‘Well, can we do it?’ to, ‘Yes we can, if we work together.’”

Although achieving a 50% damage reduction in 5 years is ambitious, the CGA had a significant advantage when presenting this challenge to its stakeholders: it had already been accomplished in the City of Chicago, one of the nation's largest and most utility-dense cities.

A construction worker in a hole in a city street. — With more utilities being installed underground than ever before, mitigating damage to existing buried infrastructure during excavation has taken on a new level of importance.

Chicago is one of only two cities – along with New York City – to have its own 811 One-Call System.

811 is the nationwide call-before-you-dig service. Since 2005, federal law mandates that contractors and excavators call 811 before starting any digging to determine the approximate location of public utilities in the area.

What distinguishes 811 Chicago from other 811 services is its project design review process, which lays the groundwork for safe excavation involving utility projects. As detailed in a CGA case study, this approach has led to a 50% decrease in annual damages in the city since 2017.

“811 Chicago’s damage prevention model is unique, and features aspects that other stakeholders may not be able to adopt within the current system in their state or region – namely enforcement authority and oversight of the OUC [Chicago’s Division of Infrastructure Management’s Office of Underground Coordination],” the CGA wrote in its case study. “But there are many aspects of 811 Chicago’s process that any stakeholder, regardless of local regulation, can incorporate into their damage prevention process.”

Any potential utility locating project in Chicago starts with a project design review, which the CGA says emphasizes collaboration and communication among project owners, engineers, and facility operators. As part of the review, project owners submit the location of the project, and the OUC sends them a utility atlas page that identifies the locations of most of the buried utilities in the vicinity of the project location.

The project owner must integrate the data from the utility atlas into an updated project plan that avoids existing utilities. This revised plan is then submitted back to OUC, which forwards it to its member utility owners for review. They examine the plan to ensure that the proposed utility will not interfere with their facilities.

The project gains approval only when all members concur on the revised plans. If any member requests modifications, the project planners must incorporate these changes before proceeding to the permitting phase.

“Projects approved by the OUC ensure a new facility’s potential impact on existing infrastructure is mitigated before the ground is broken,” the CGA wrote. “The OUC returns value to both utility owners and excavators by saving them costs associated with utility damages.”

Lyle shared with The Built World that the CGA was particularly impressed by the transparent communication among stakeholders regarding subsurface utility mapping when they reviewed the data from 811 Chicago.

The CGA’s case study highlights dotMaps as a key factor in Chicago 811's success. This custom-built GIS mapping tool displays the locations of OUC projects, permits, and dig tickets. Stakeholders utilize dotMaps to research both completed and upcoming infrastructure projects. Project and utility owners coordinate their efforts using the data, field crews access it for on-site information, and the public can view ongoing utility projects in their neighborhoods.

“Five years ago, it was ‘We can’t do that,’” Lyle said. “Now we have a lot of places that have shown us we can, and so that, to me, stuck out. Yes, we can provide access to mapping, and we can provide access to this information, and it actually does make the system better. They’ve shown that mapping tools work.”

Discussing BIM Standards And Laser Scanning

A Building Information Model is a 3D digital representation of a building’s features and measurements that is used by everyone from real estate developers to architects and building designers to construction contractors to plot, plan, design, prefabricate elements offsite, and collaborate on any building, retooling, or renovation project before anyone even breaks ground.

What is a Building Information Model (BIM Model) & How are They Used?

Here’s the NIBS (The National Institute of Building Sciences) definition of a BIM model: “A BIM is a digital representation of physical and functional characteristics of a facility. As such it serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its lifecycle from inception onward.”

‍

Standards for BIM Models in Design

The construction, engineering, and architecture industry has seen a recent update from NIBS (The National Institute of Building Sciences) regarding their ongoing initiative to create a nationwide standard for BIM models in design.

September 2022 marks the third update to the proposed National BIM Standard, for which NIBS chartered its BIM Council in 2005. Now known as the Building Smart Alliance, they have been working for more than a decade to create and reach consensus on a national standard, and their first nationwide BIM standards release occurred in 2007. The new standards just issued by NIBS are known as NBIMS-US™ V3 and are included in a 3,100-page document laying out the rationale behind the collaborative effort to create the standards and how they can be effectively implemented.

‍

Adopting New Technology in Data Capture for BIM Modeling

It is now possible, and even desirable, for as-built, existing structural elements to be measured and captured by 3D laser scanning, which utilizes LiDAR (light detection and ranging) at the rate of 2 million data points per second to provide structural features and measurements with millimeter accuracy. That data, organized as a point cloud, is then sent to CAD designers BIM Managers, Virtual Design Construction teams (VDCs), and technicians to fabricate the digital model with similar accuracy and attention to detail.

However, as pointed out in a recent Yahoo News article, the architecture, engineering and construction industries have been slow to embrace digitalization for construction projects. In many cases, architects and builders rely on manual measurements which can be as much as a full foot off. BIM models created with those measurements make clash detection/avoidance and off-site prefabrication difficult. Manual measuring for BIM can cause huge cost overruns, change orders, and lost time on the job when the data proves to be inaccurate.

“A critical issue in the U.S. construction industry is its low level of digitalization, which prevents it from transforming lifecycle work processes to be more efficient, less expensive, more resilient, and safer to build and maintain.” – Yahoo News

It makes sense, given the vast differences in modeling practices across the construction and design disciplines, to find a common standardization. Which is why in June of this year, NIBS brought in AEC specialist Johnny Fortune to oversee their national BIM initiative.

Additionally, the Building Smart Alliance cites the statistic that a mere 1% improvement in productivity in the architecture and construction-related industries has been achieved in the last 20 years, although the technology exists to vastly improve the timeliness, cost-effectiveness, and safety on construction and renovation jobsites.

Which is why they brought together 40 industry leaders to explore the subject and collaborate on best practices for version 3.

‍

Where Does 3D Laser Scanning Fit In?

LiDAR News, a leading industry publication, had this to say about the upcoming V3 standards in February of 2022:

“The transformation in the building industry fostered by the evolution from use of analog drawings and text to the use of digital electronic Building Information Modeling (BIM) is comparable to the transformation that has already occurred in the aircraft, microprocessor, and automotive industries. Early definitions, which assert that BIM is simply a 3D model of a facility, are far from the truth and do not adequately communicate the potential of digital, object-based, interoperable building information modeling processes and tools and modern communications methods.”

There seems to be a persistent omission from NIBS massive standardization initiative: The use of 3D laser scanning technology. This omission is confounding, considering its popularity and use for structural measurements and building feature capture across the architectural, construction, and engineering spaces.

3D laser scanning with LiDAR is considered the most efficient, effective, and accurate measuring tool available to architects and designers because it can reduce measuring times down to a few hours, and instantly capture data and photogrammetry, so that CAD designers and Autodesk technicians can easily rectify the point cloud and images to provide an accurate and immediately accessible BIM model, along with drawings, maps, and even complete walkthrough and flythrough tours of the BIM.

GPRS' Director of Laser Scanning, Nate Baker, had this to say about the importance of 3D laser scanning in the BIM world and why standardization matters. “Laser scanning is typically the basis or starting point for an architect, engineer, GC, etc., when they don’t have good or existing drawings. So, we need to come up with a standard way of communicating expectations for all stakeholders.”

Baker voiced his opinion on the seeming continued omission.

“I think [standardization] is great… but it doesn’t really address laser scanning. For example, an LOD 400 model [a type of BIM] should include window internal mechanisms in the model by definition. With laser scanning, we are limited to line of sight, so we are not able to see those features and therefore cannot capture them in our data or model them. The USIBD has tried to fill this gap, but even they focus more on defining accuracy and less on defining what we will be capturing and how we will be modeling it.”

The organization Baker referred to, USIBD, is the U.S. Institute of Building Documentation, and fills a role adjacent to that of NIBS: to “establish standards, guidelines, and best practices to foster excellence in productivity, quality and safety of the documentation process.” It does not, however, specifically address 3D laser scanning’s role in data capture for BIM, although it is trying to bridge that gap.

When asked if he believes NIBS will succeed in its third BIM standardization attempt, Baker replied, “Yes, I do. There is a huge need for it, but I do wish they specifically addressed laser scanning. Laser scanning is a huge part of capturing as-built/as-is conditions, and so I think it should not be overlooked.”

Scan-to-BIM modeling services, like those provided by the Mapping & Modeling Team, are constructed with a wide range of software, but the goal is the same: to construct a true digital twin of the existing as-built structures to streamline data sharing, coordination, and management on the project.

Building Renovations Surpass New Construction In 2022

The renovation of older buildings in US cities recently hit a record high. As of spring 2022, 52% of architecture firm billings came from renovation work, not new construction, according to the American Institute of Architects (AIA).

For the first time in 20 years, renovations have overtaken new construction in architectural billings in the Unites States.

In 2005, renovations made up 34% of billings. In 2017, it was 44%. Bloomberg reports that renovations have surpassed 50% for the first time in 20 years.

Renovations, rehabilitations, additions, and historic preservation as a percent of firm building design billings.

Why Building Renovations Happen

Changes in building function are the major cause for renovations. Kermit Baker, AIA’s chief economist, asked architecture firms about the most important goal of reconstruction projects they have worked on in the last 12 months and compiled these statistics:

26% adaptive reuse/conversion
24% basic interior modernization
18% tenant fit-outs
10% adding usable space
6% upgrades to building shell
5% upgrades to building systems
4% energy performance
3% historic preservation
2% improve the resiliency of the building

Architectural firms reporting what has been the single most important goal of reconstruction projects that their firm has worked over the past year.

Accurate Site Data for Building Renovations

Renovations can reverse the trend of demolishing buildings and save them by reusing them. “There is an opportunity to adapt or renovate what we already have,” says Ryan Hacker, Director of Laser Scanning. He adds, “The challenge is that the architect may not have access to accurate as-built site data to complete these renovations.”

There are many concerns when it comes to renovating a structure which does not have the original construction drawings. The architect does not have access to the actual building or site dimensions. 3D laser scanning is the perfect solution to this problem. Exact dimensions and measurements of a building can be obtained in an efficient, accurate and safe manner.

Here are a few project examples where laser scanning can be valuable: expansion of a data center, office buildings being fitted with new amenities, manufacturing facilities adding new production lines, hotels catching up with deferred maintenance, and parking garages getting upgrades.

3D Laser Scanning Can Benefit a Renovation Project

Understanding how 3D laser scanning can benefit your renovation project is an important step in project planning, whether you’re embarking on a building renovation or facility maintenance. As-built laser scanning allows you to gather accurate, detailed information about existing site conditions. Data is collected in the form of a point cloud, a database of millions of points in a 3D coordinate system. Accurate to within millimeters, laser scanning captures a precise digital record of a building or site.

What are the Benefits of 3D Laser Scanning?

3D laser scanning offers the following benefits for renovation, retrofitting, restoration, and construction projects:

Fast, Accurate Data Collection: A single laser scan captures millions of 3D data points per second, providing comprehensive as-built information of a building or project site.
Data Shared Across the Project Team: Datasets are dimensionally accurate, measurable, and shareable, expediting project planning and execution.
Eliminates Site Revisits and Disruption: Sites are captured in high detail the first time, eliminating the need for return visits. High speed data collection expedites projects that require minimal disruption.
Reduced Costs and Change Orders: Accurate design plans are produced from the start, expediting field work and reducing change orders, delays, and costs.
Safe and Non-Contact: 3D laser scanners collect data on tripods from a distance in hard to reach or hazardous locations, keeping workers safe. The non-intrusive nature keeps historic sites and artifacts untouched.
Custom Deliverables: 2D CAD drawings, 3D mesh, and 3D BIM models can be produced at any level of detail. TruViews and virtual tours can be used to visualize the site.
Improved Communication: Teams can discuss plans while each has access to the same information, creating a more dynamic working environment.

Before beginning your renovation, retrofitting, or restoration project, laser scanning can grant architects, contractors, and sub-contractors access to accurate data to quickly move through the design phase. Utilizing laser scanning can offer many benefits and ensure a successful project outcome.

3 Ways General Contractors Reduce Costs With 3D Laser Scanning

3D laser scanning and mapping methodologies are commonly used to capture the most accurate data for every architectural, structural and MEP detail of your site. This technology is applicable throughout the design, construction, operations, retrofit, and renovation stages of any construction project’s lifecycle.

In a recent article published by Autodesk Inc., 3D laser scanning, “also known as high-definition surveying (HDS) or reality capture,” was described as a “means of using a laser to map an area with high accuracy,” for a given construction project.

Data collected from this process provides facility managers, engineers, and other construction professionals with what is known as a point cloud. This is a database, which connects points within a 3D coordinate system, maintaining an “extremely accurate digital record of an object or space as it pertains to a project.”

Given their ability to improve quality and accuracy, provide immediate information, reduce manual labor, streamline coordination, and greatly cut costs, it’s no surprise that 3D laser scanning techniques have grown in popularity over the past few years.

In an interview with Aaron Seymour of the Rudolph Libbe Group, Seymour explained how GPRS 3D Laser Scanning is his choice measurement method for any construction project he’s assigned because it can save on time-consuming measurements and greatly cut costs. He elaborates on the fact that, "without the laser scanning capabilities that GPRS provides, we would have to hire an architect that would have to go through and do manual assessments and measurements in order to provide us with a set of drawings that we can actually build off of," which is a far more expensive and lengthy process.

However, using the modern techniques of GPRS Laser Scanning, we help project managers like Aaron fully visualize site data both above and below ground. Once all necessary data is collected by project managers and modeled by CAD technicians, it can then be easily stored and viewed using SiteMap^®’s Map Viewer and Digital Plan Room.

‍

3D laser scanning captures the most accurate data for every architectural, structural and MEP detail of your site.

‍

There are three major ways in which 3D laser scanning can eliminate unnecessary costs for your construction project.

1. Measurement Accuracy

With more traditional methods of job site measurements, General Contractors usually have to hire an architectural firm to come in and manually collect all of the required measurements needed to create a set of drawings from which any construction plans or 3D model could be made.

However, this process has a very high chance of human error given that all measurements are taken and recorded by hand. This often results in inaccuracy up to a full foot, and therefore, major redesign costs later down the line after construction has already begun and such oversights stall any further progress.

On the other hand, with GPRS 3D Laser Scanning Services, complete as-builts can be captured with a far more reliable 2-4 mm level of accuracy, eliminating the redesign costs associated with traditional hand measurement techniques.

2. Efficient, Time-Saving Data Collection

Typical hand measuring techniques can take months if not years to be completed. Such delays can be very costly and greatly jeopardize the success of any project.

However, using 3D laser scan technology, it will only take about 1-2 days in most cases for our Project Managers to completely scan a job site. Afterwards, our CAD team can interpret the collected data to accurately generate the comprehensive maps, models, and drawings your project needs to move forward.

This modernized process can assess any location with high precision, allowing our customers to confidently execute their vision in a matter of days instead of weeks or even months.

3. Customizable 3D Models

3D laser scanning is also great at minimizing cost particularly because of its flexible, customizable approach to 3D modeling project sites. Not all aspects of the project site need to be modeled. The features are modeled to your project’s specific scope and LOD, as defined in the proposal. By using these detail specifications to scope projects, precision requirements of the BIM model are clearly communicated for faster project execution. 3D BIM models are revolutionizing the way projects are delivered across industries, adding intelligence and efficiency to project execution.

3D models and additional deliverables are stored in SiteMap^® for easy access and faster collaboration. SiteMap is a cloud-based digital platform designed to be an easy-to-use portal, containing your accurate, and up to date “as-built” drawings all in one place. Designed with an intuitive user interface, SiteMap^® delivers permanent records of site assets and infrastructure.

In Conclusion

How GIS-Based Infrastructure Mapping Breaks Down Communication Silos in the Construction Industry

The success of your next construction project hinges on you being able to seamlessly communicate with your team, your subcontractors, and everyone else on the job site.

You can’t afford to have communication silos disrupt your planning and project execution. Yet we know that these silos are one of the construction industry’s most persistent challenges, as information is compartmentalized within specific groups of departments and efficiency and effectiveness is hindered.

Fortunately, the advent of GIS-based infrastructure mapping software offers a powerful solution to break down these barriers and foster a more integrated and collaborative working environment.

People working around design plans. — Communication silos are one of the construction industry’s most persistent challenges, as information is compartmentalized within specific groups of departments and efficiency and effectiveness is hindered.

Understanding Communication Silos in Construction

Communication silos in construction often arise due to the complex and diverse nature of projects. Construction typically involves multiple stakeholders, including architects, engineers, contractors, subcontractors, and clients, each with their own specialized roles and responsibilities. These groups frequently operate in isolation, with limited sharing of information across departments. This fragmentation can lead to several problems:

Delayed Information Flow: When information is not shared promptly or accurately, it can cause delays and misunderstandings, leading to project setbacks
Inconsistent Data: Different teams might work with varying versions of project data, resulting in inconsistencies and potential errors in planning and execution
Increased Costs: Miscommunication and errors due to silos often result in rework and additional expenses, inflating project budgets
Safety Risks: Inaccurate or untimely information can compromise safety, putting workers at risk and potentially leading to accidents or hazards on the construction site

Given these challenges, addressing communication silos is crucial for the efficiency, cost-effectiveness, and safety of construction projects.

The Role of GIS-Based Infrastructure Mapping

Geographic Information Systems (GIS) have revolutionized many industries by providing tools to visualize, analyze, and interpret spatial data. In the context of construction, GIS-based infrastructure mapping software serves as a critical tool to bridge communication gaps. This technology integrates spatial data with project information, offering a comprehensive view of the project landscape that is accessible to all stakeholders.

Here are some ways which GIS-based infrastructure mapping helps eliminate communication silos in construction:

Centralized Data Repository: GIS software consolidates all project data into a single, centralized platform. This includes everything from site layouts and topographical maps to utility networks and environmental assessments. By having all information in one place, it ensures that everyone involved in the project has access to the most up-to-date and accurate data.

Enhanced Collaboration: With a centralized data repository, different teams can collaborate more effectively. GIS platforms often feature tools that allow for real-time updates and sharing of information, meaning changes or updates to project plans are immediately visible to all relevant parties. This transparency facilitates better coordination and reduces the likelihood of miscommunication.

Improved Decision-Making: Access to comprehensive spatial data enables more informed decision-making. Project managers can visualize the project site in detail, identify potential issues before they arise, and make proactive adjustments to the project plan. This foresight helps in mitigating risks and optimizing resource allocation.

Streamlined Workflow: GIS-based tools automate many of the processes involved in data management and analysis. For example, they can automatically update maps with the latest construction progress or detect clashes in planned infrastructure. This automation reduces manual effort and ensures that everyone is working with the latest information.

Stakeholder Engagement: Effective communication with external stakeholders, such as clients, regulatory bodies, and the public, is crucial in construction projects. GIS platforms can create interactive maps and visualizations that are easy to understand, helping to communicate complex project details clearly and concisely. This not only enhances transparency but also builds trust and engagement with stakeholders.

Spatial Analysis and Reporting: GIS software can perform sophisticated spatial analyses, such as identifying optimal locations for new infrastructure or assessing the impact of construction on the environment. These analyses are invaluable for planning and can be easily shared across teams to align on strategic decisions.

Practical Applications in Construction

To illustrate the impact of GIS-based infrastructure mapping in breaking down communication silos, consider the following practical applications in the construction industry:

Site Planning and Design: During the initial phases of a project, GIS tools can integrate various data sources to create detailed site plans. These plans can be shared with all stakeholders, ensuring that everyone has a common understanding of the site conditions and constraints.

Construction Management: Throughout the construction phase, GIS platforms can help managers monitor progress and provide real-time updates on the status of different project components. This continuous flow of information keeps all teams aligned and allows for quick adjustments if any issues arise.

Asset Management: Post-construction, GIS can be used to manage and maintain infrastructure assets. For instance, utility companies can use GIS maps to keep track of underground pipelines and cables, facilitating efficient maintenance and minimizing disruptions.

Disaster Response and Recovery: In the event of natural disasters, GIS-based mapping can quickly assess damage and coordinate response efforts. By providing accurate and timely information, it helps in deploying resources effectively and restoring infrastructure promptly.

These upgrades wouldn’t have been possible without the architects, contractor, and subcontractors on the project first gaining an understanding of the existing built world beneath the airport. Technologies such as ground penetrating radar (GPR) and GIS-based utility mapping support infrastructure projects such as the Terminal E expansion by visualizing what’s below, so that dangerous and costly subsurface damage can be avoided during excavation.

Existing conditions as-builts serve as a guide for construction planning, allowing the construction team to construct and plan with confidence. Subsurface utility locating and concrete scanning are vital to ensuring the safety and success of terminal construction and design, helping you see the unseen and ensure the safety of everyone involved in the project.

The namesake of GPRS, GPR works in concert with other technologies to identify buried objects and underground utilities. GPRS Project Managers provide 99.8%+ accurate, field-verified utility maps, all securely accessible 24/7 from any computer, tablet, or smartphone via SiteMap^® (patent pending). Our in-house Mapping & Modeling Team can export the GPR scans to create accurate existing conditions as-builts to give you the information you need in a format you can easily work with to stay on time, on budget, and safe.

Active electromagnetic (EM) locating involves actively transmitting a frequency through the underground utility’s conductive material. This is done by connecting through various points depending on the utility. The transmitter can be connected to various types of utility lines via a grounding wire or other physical utility structure above ground to provide the active signal that the EM locator can then read.

EM locators are preferred by One Call contractors to locate public utility lines. GPRS utilizes these devices with GPR and other technologies as part of the Subsurface Investigation Methodology (SIM) process to detect live AC power or radio signals along conductive utilities.

GPRS Project Managers use robotic crawlers and push-fed sewer scopes equipped with CCTV cameras and sondes as part of our Video Pipe Inspection services, which provide accurate sewer pipe visualization.

Terminal E stands as a shining example of architectural innovation and strategic planning in the realm of air travel – but it would not be possible without first mapping what’s below.

Explaining Urban Stormwater Capture

Urban stormwater can be more than just a nuisance.

That’s the takeaway from a report released recently by global water think tank the Pacific Institute and 2NDNATURE Software Inc., a provider of stormwater management software.

The report, titled Untapped Potential: An Assessment of Urban Stormwater Runoff Potential in the United States, says there are multiple ways that cities in the U.S. – particularly those in coastal regions, could make greater use of stormwater, which is typically seen today as a nuisance to be removed as quickly as possible.

Stormwater runs into rain gardens. — (Photo courtesy of NYC Water) Rain gardens like these in New York City are an example of the increasing efforts to capture urban stormwater and put it to good use.

“…Water scarcity is a growing risk due in part to natural hydrologic variability, population and economic growth, and the intensifying effects of climate change,” the report reads. “Yet, traditional water sources, such as freshwater from rivers and streams and underground aquifers, are increasingly facing peak water limits. These constraints have led water providers to adopt water conservation and efficiency to reduce demand and develop new, alternative water supply strategies, such as reusing treated wastewater and capturing urban stormwater runoff.”

Urban stormwater – runoff generated from precipitation falling on rooftops, roads, and other impervious surfaces in urbanized areas – has historically been considered a nuisance or hazard because it carries pollution from roads and other urban surfaces to rivers, lakes, estuaries, and the ocean, threatening both aquatic life and public health. Additionally, it can lead to flooding that causes property damage and risks for communities.

Because of these risks, urban areas are typically designed with dedicated storm sewers to collect and dispose of the runoff into nearby waterways or detention ponds as quickly as possible. However, as water scarcity as become an increasingly serious problem across the globe, more and more cities are looking at a way to capture stormwater and put it to good use.

In Los Angeles County, more than 27,000 acre-feet (8.8 billion gallons) of stormwater is captured annually at centralized spreading grounds where it recharges groundwater in the San Fernando Groundwater Basin. And in New York City, curbside rain gardens capture stormwater to help reduce the risk of flooding.

Stormwater capture is also garnering increased attention and support at the federal level. The United States Environmental Protection Agency’s (EPA) Water Reuse Action Plan (WRAP) provides a roadmap for collaboration and action to implement water reuse strategies across the United States.

The Untapped Potential report details how stormwater capture can be achieved at a variety of scales, and include traditional gray infrastructure, such as storm sewers and combined sewers that route stormwater to a treatment facility or storage pond for infiltration, or green infrastructure, such as bioswales and rain gardens that use plants and soils to slow, filter, and store stormwater before it enters the storm system. A mix of both gray and green infrastructure can also be used to capture stormwater.

“…[Reusing treated wastewater and capturing urban stormwater runoff] can help ‘close the gap’ between existing and anticipated water supply and demand and support long-term water resilience,” the report reads.

Water lines can develop links that cost you tens of thousands of dollars in non-revenue water (NRW) loss. And sewer lines can be compromised by defects such as inflow/infiltration (I/I) and cross bores, which can threaten the health and safety of entire communities.

GPRS leak detection and video pipe inspection (VPI) services help you maintain, preserve, and update your water and wastewater infrastructure. Using acoustic leak detection and leak detection correlators, our water loss specialists locate leaks and provide insights into your water distribution system. And on the wastewater side, our NASSCO-certified VPI Project Managers use sophisticated, remote-controlled sewer inspection rovers and push-fed scopes equipped with CCTV cameras and sondes: instrument probes that allow us to map your sewer and stormwater systems while we’re inspecting them for defects.

From skyscrapers to sewer lines, GPRS Intelligently Visualizes The Built World^® to keep your projects on time, on budget, and safe.

Frequently Asked Questions

How many miles of water lines can GPRS inspect in one day?

Our professional leak inspection specialists can test up to 10 miles of pipe a day on a metallic system (cast iron/ductile) and can test a contact point (hydrant/valve) within a minute before moving on to the next one. They’re able to work so efficiently because they are trained to hear the specific tone that a leak produces compared to any other number of noises a general environment makes.

Can a GPRS Project Manager determine the size of the leak they’ve detected?

We can determine the size of the leak by how far the leak signal travels between contact points and the pitch of the tone received. We do not, however, produce formal leak size estimation reports.

What size wastewater pipes can GPRS inspect?

Our elite, NASSCO-certified Project Managers have the capabilities to inspect pipes from 2” in diameter and up.

What deliverables does GPRS offer when conducting a sewer pipe inspection?

GPRS is proud to offer WinCan reporting to our Video Pipe Inspection clients. Maintaining sewers starts with understanding sewer condition, and WinCan allows GPRS Project Managers to collect detailed, NASSCO-compliant inspection data. GPRS Project Managers not only inspect the interior condition of sewer pipes, laterals, and manholes – they can also provide a map of their location. The GPRS Mapping & Modeling Department can provide GPS overlays and CAD files. Our detailed WinCan/NASSCO reports contain screenshots of the interior condition of the pipe segments that we inspect, as well as a video file for further evaluation, documentation, and/or reference.
