GPRS Located, marked, and mapped all utility and sewer lines at Manufacturing Facility, and provide comprehensive infrastructure data management for O&M purposes. The manufacturing facility needed a permanent record of their 60-acre facility’s buried infrastructureData needed to be secure, yet easily accessible for facility manager and their teamPerdue previously spent $100,000 on a full site scan, but the contractor left them with only the field markings and hand-drawn utility maps The manufacturing facility was familiar with GPRS’ capabilities, having previously hired us for utility locatesExisting relationship between the two companies led to the manufacturing facility hiring GPRS to locate and map the entire facility’s buried infrastructure, and conduct drone flyovers of the siteThis accurate, field-verified data was uploaded into SiteMap® Pro, where the manufacturing facility has 24/7, secure access The facility had secure, 24/7 access to accurate, field-verified infrastructure data that they can use for future O&MGPRS and the facility entered into a SiteMap® Pro agreement, where Perdue will pay a subscription fee to continue to have access to their infrastructure data

General SOQ

The deliverables provided will be an asset for years to come as they can be referenced for any future coring or drilling needs showing where everything embedded in the slab was prior to pouring.

The client was in active build of an eight-story apartment complex in Houston, Texas. Each floor had five to six concrete pours scheduled on specific dates over an 8-month period. GPRS 3D laser scanned each area to capture the existing conduit, post-tensioning, rebar plan and sleeves prior to the slab being poured. This allowed the client to check the existing conditions for any irregularities.

Location: Houston, Texas Task: The client was in active build of an eight-story apartment complex in Houston, Texas. Each floor had five to six concrete pours scheduled on specific dates over an 8-month period. GPRS 3D laser scanned each area to capture the existing conduit, post-tensioning, rebar plan and sleeves prior to the slab being poured. This allowed the client to check the existing conditions for any irregularities. Challenge: The client was on a strict timeline and did not want delays in construction. They needed to quickly and accurate ensure that everything was in its correct location prior to pouring the slab. The client needed a 3D laser scanning company who could quickly mobilize to the site, conduct efficient laser scanning and provide point cloud data aligned to the design drawings within 24-48 hours. Solution: GPRS worked closely with the client. The scan technician mobilized to the site 1-2 times a week for 8 months and quickly captured the data without stalling the construction process. The scan technician set up the laser scanner at multiple locations around each slab and captured the data without disturbing the active construction site. GPRS’ team of in-house engineers quickly provided the point cloud alignment. The sub-centimeter point cloud data allowed the client to review the site conditions and make changes prior to the scheduled pour and without ever having to leave the office. Deliverable: GPRS’ Project Manager laser scanned each area and provided a colorized point cloud to the client. The colorized point cloud allowed the client to see color imagery, stitched over the point cloud to assess the area for misplaced sleeves, conduits and post-tension runs. This data was also aligned to the existing building plans to quickly find any issues. Added Value: The client relayed that GPRS saved them thousands of the dollars with just the first mobilization. They identified issues with the sleeve alignment from the home office and had them corrected prior to the slab being poured. Finding out that the sleeves were not in the correct location, even the day after the pour, would have cost the general contractor tens of thousands of dollars in coring costs alone. And if this problem would not have been discovered until framing and other elements went up could have cost exponentially more. GPRS’ nationwide team of scan technicians that can mobilize to any site quickly. Our experience and long-term client commitment make us a great partner for your 3D laser scanning needs. 3D high-definition surveying has proven to be a quick, accurate, and versatile tool for architects, engineers, BIM managers, general contractors, and construction managers. It is ideal for adaptive reuse or renovation projects. In this case, GPRS provided the client with invaluable information that allowed them to assess the site from their office before the concrete slab was poured. The deliverables provided will be an asset for years to come as they can be referenced for any future coring or drilling needs showing where everything embedded in the slab was prior to pouring. From skyscrapers to sewer lines, GPRS Intelligently Visualizes The Built World® to keep your projects on time, on budget, and safe. What can we help you visualize?

3D Laser Scanning

GPRS’ detailed 2D CAD drawings and 3D BIM model allow for safe cutting, coring & drilling for building-wide MEP and HVAC installations.

GPRS located and marked the full post-tension cable system layout for 12 floors of a 49-floor building, with approximately 12,500 sq. ft. of concrete on each floor. After concrete scanning was completed with ground penetrating radar technology, GPRS 3D laser scanned each floor to produce 2D CAD drawings and a 3D BIM model for virtual design and construction. The architect received a permanent record of the post-tension cable layout to complete fit and finish design plans for the building.

Mapping the PT cable layout in concrete slabs facilitates design and minimizes the risk of injuries and delays.

GPRS’ detailed 2D CAD drawings and 3D BIM model allow for safe cutting, coring & drilling for building-wide MEP and HVAC installations. Construction Concrete Scanning, 3D Laser Scanning & 3D BIM Modeling Concrete scanning services will locate critical targets like post tension cables, rebar, conduits, voids, and more to help keep your project on time, on budget, and safe. 3D laser scanning captures concrete markings with 2-4mm accuracy for GPRS to transform into custom 2D CAD drawings and 3D BIM models. GPRS located and marked the full post-tension cable system layout for 12 floors of a 49-floor building, with approximately 12,500 sq. ft. of concrete on each floor. After concrete scanning was completed with ground penetrating radar technology, GPRS 3D laser scanned each floor to produce 2D CAD drawings and a 3D BIM model for virtual design and construction. The architect received a permanent record of the post-tension cable layout to complete fit and finish design plans for the building. Post-tension cable location, spacing, and depth are determined by an engineer, are specific to each project, and must be traced in short distances to reveal the slope. Each tendon pulls 24,000 to 33,000 lbs. of pressure. Damaging a cable when cutting, coring, or drilling into a slab can cause a tendon to burst with enough force to cause severe injury or death, and impact the structural integrity of the slab. Replacing a single post-tension cable costs $10,000 - $20,000. Experienced Project Managers used ground penetrating radar (GPR) technology to locate and mark the precise details of each concrete reinforcement, documenting the location, number of cables, and depth directly on the slab and ceiling. After the post-tension layout was complete, each floor was 3D laser scanned to capture the field markings. That data was used to create a virtual tour, 2D CAD drawings (PT site layout and floor contours,) and a complete 3D BIM model of the site. The captured point cloud data was aligned to survey control, then to the client’s design model, further ensuring the accuracy of the data. GPRS has a verified 99.8% accuracy rate for concrete scanning, backed by our Green Box Guarantee. Laser scanning is accurate within 2-4mm. An accurate layout of post-tension cables protects tendons from damage, prevents injury and mistakes, and protects the integrity of the building. 2D plan sheets and a 2D floor contour map documenting the actual floor elevation added even more accuracy to the depth of cover that is field marked. The 3D BIM model provided the architect data to plan fit and finish designs and coordinate with contractors and MEP trades before build-out.
