Build at the speed of Insight



Accurate measurements help you avoid expensive mistakes, reworks, and change orders. GPRS 3D Laser Scanning services provide 2-4mm accuracy by capturing 2 million data points per second, for efficient planning, design, and construction.

///You can’t afford clashes, change orders & mistakes. Neither can we.

GPRS’ in-house Mapping & Modeling Team can export your GPR utility locates & concrete scans, 3D laser & photogrammetry data, and video pipe inspection reports to create accurate existing condition as-builts – above and below ground – to give you the accurate information you need in a format you can easily work with and share to keep your project on time, on budget, and safe.

///Case Study

Accurate PT Cable Layout 
Critical to Construction:
Accurate existing condition as-builts with 2D plan views of your above and below ground infrastructure to break down information bottlenecks with comprehensive, layered data.
GPRS located and marked the full post tension cable system layout for floors 12-23 of a 49-story 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 12 floors of the building.

PT Cable Layout
Chat box with question mark | GPRS
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, so 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.

Replacing a single cable can cost more than $10,000.
Magnifying glass with check | GPRS
GPRS used ground penetrating radar (GPR) to locate and document each concrete reinforcement, including number of cables and depths directly on the slab.

PMs then captured the slab markings with 3D laser scans to create:

  • A WalkThru 3D virtual tour
  • 2D CAD drawings of PT site layout & floor contours
Captured point cloud data was aligned to both survey control & the clients design model to ensure data accuracy.
Notebook with checks | GPRS
GPRS’ 99.8%+ accurate concrete imaging is backed by our Green Box Guarantee. Capturing mark-outs via 3D laser ensures 2-4mm accuracy in documentation.

Accurate PT layout documents protect against damaged tendons, mistakes, and injuries to ensure building integrity.

2D plan sheets & contour maps enhanced depth-of-cover as-built accuracy.

3D BIM model provided 2-4mm accurate data so the architect could plan, design, and coordinate with contractors prior to build-out.
