BIM Model Aids Design Renovations for Stadium A BIM model provided the stadium owners a better understanding of the design updates. Tallahassee, Florida Task: An architect requested an ArchiCAD BIM model of a college football stadium to create renovation construction documents. Problem: A vast amount of space required as-built documentation, over 600,000 sq. ft. needed 3D laser scanned and modeled. The renovation changes were complex. A BIM model was needed to provide the stadium owners a better understanding of the architecture and design updates. Our client needed a single source of data, where all architects on the team could see the latest design and document their changes. Solution: The exterior and interior of the stadium were 3D laser scanned with 2-4 millimeter precision, including three concourse levels, stadium seating, and suites. TruePoint delivered an intensity map point cloud, TruView viewer files, and a Revit 2021 3D model of the stadium. Working from precise details in the 3D model, renovations can be designed right the first time, saving time and costly change orders. Benefits: The architect utilizes the Building Information Modeling (BIM) process to provide their clients a better understanding of the complexities of architecture and design. Technical construction drawings (floor plan views, elevation views, cross-sections, iso-metric representations, etc.) can be effortlessly created from the 3D BIM model and shared with all disciplines. A BIM model allows architects to plan precise renovations, from design changes and material selection, to cost estimation and construction phasing.

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.

3D Laser Scanning

GPRS used 3D laser scanning and BIM modeling to support Whiting-Turner’s renovation of one of the most critical telecom hubs on the West Coast.

GPRS partnered with Whiting-Turner to 3D laser scan 200,000 square feet of the Pittock Block Internet Exchange in Portland, Oregon, an eight story, 302,262 square foot carrier hotel, data center, and office space. Built in 1914, the historic building was adaptively reused from an electric substation into a modern data center that now hosts one of the highest densities of telecom networks and carriers on the West Coast. Whiting-Turner planned renovations to tenant and common areas on the ground, mezzanine, fourth, and eighth floors, including new entry vestibules, infrastructure upgrades, support rooms, and façade modifications. To support this work, GPRS captured as-built data of the building to generate a point cloud, CAD drawings, and Autodesk Revit Model.

Task GPRS partnered with Whiting-Turner to 3D laser scan 200,000 square feet of the Pittock Block Internet Exchange in Portland, Oregon, an eight story, 302,262 square foot carrier hotel, data center, and office space. Built in 1914, the historic building was adaptively reused from an electric substation into a modern data center that now hosts one of the highest densities of telecom networks and carriers on the West Coast. Whiting-Turner planned renovations to tenant and common areas on the ground, mezzanine, fourth, and eighth floors, including new entry vestibules, infrastructure upgrades, support rooms, and façade modifications. To support this work, GPRS captured as-built data of the building to generate a point cloud, CAD drawings, and Autodesk Revit Model. PROBLEM Renovations and infrastructure upgrades needed to be completed without disrupting ongoing tenant operations or critical systems. The facility could not experience downtime, as it housed 16 fiber optic carriers, 179 service providers, and seven subsea cables critical to its role as a global grade Internet Exchange. Renovations across multiple levels, including the ground, mezzanine, fourth, and eighth floors, had to modernize shared spaces, infrastructure, and systems while maintaining uptime. Entry vestibules needed to be updated in a way that enhanced security, yet preserved smooth tenant and visitor flow. Specialized rooms had to be designed and constructed to support IT infrastructure and facility operations while meeting strict technical requirements. Ground floor facades required modification while preserving the building’s historic character. Infrastructure and systems essential to data center operations had to be upgraded to ensure reliability, scalability, and compliance with industry standards. Scheduling challenges had to be addressed when certain areas were unavailable for scanning or construction due to demolition or phased work. ‍ Solution GPRS’ Project Manager captured 200,000 square feet of space with the Leica RTC360 scanner at 2-4mm accuracy, completing 504 individual laser scans. Two mobilizations were conducted to ensure complete coverage of the basement, levels 1–4, level 8, and the roof. All architectural, structural, and MEP systems, including data closets and cooling systems, were documented in a colorized point cloud, capturing walls, floors, ceilings, doors, windows, roof infrastructure, exposed columns, beams, stairs, piping, conduit, and ducts. An Autodesk Revit 3D BIM model was generated to provide precise details of the data center’s spatial relationships, geometry, structure, and systems. From the BIM model, 2D CAD drawings were produced to support pre-construction planning, enabling teams to quickly understand the project scope before advancing into detailed 3D modeling. ‍ Benefits 3D laser scanning delivered a comprehensive, real time digital view of the data center, capturing precise structural and MEP layouts that seamlessly integrated with CAD and BIM for accurate planning, clash detection, and efficient construction sequencing. Deliverables were shared via SiteMap, GPRS’ secure, cloud based platform and mobile app, which centralized point cloud data, CAD files, and BIM models into an interactive tool for easy access and collaboration. With accurate facility as-builts, errors, change orders, delays, and costs were reduced during renovation. Cooling system upgrades were enhanced through precise modeling of roof infrastructure. Whiting-Turner successfully delivered turnkey data center renovations to meet tenant needs.
