Deliverables

GPRS' team of in-house engineers delivered a 3D AutoCAD model of existing structural steel aligned to existing 2D AutoCAD drawings on a 127,000 sq. ft. site. Analysis from 3D scan data is the best way to ensure precise measurements when dimensions are critical.

Task

Structural steel construction was underway on a $180 million, 127,000 sq. ft. shopping center designed to house 60 retailers. The client requested 3D laser scanning services to capture point cloud data from the structural steel and generate an LOD 200 AutoCAD model to verify the accuracy of existing 2D drawings. GPRS was tasked with 3D laser scanning the site and capturing all structural elements including exposed columns, beams and floor.

PROBLEM

Verifying the accuracy of structural steel at this stage of construction is vital. Shop drawings sometimes do not reflect actual site conditions. With a project of this scope, possession of valid 2D drawings of the existing field conditions is imperative to keep the project on schedule.

Solution

3D laser scanning measures large and complex steel structures quickly, precisely, and comprehensively. GPRS 3D laser scanning professionals used survey-grade Leica laser scanners to capture the highest quality 3D data of the site. The GPRS engineering team then converts the point cloud data into a 3D AutoCAD model and aligns it to the client’s 2D drawings. This allows structural engineers to verify the accuracy of the existing construction documentation.

Benefits

GPRS quickly mobilized to this location multiple times in order to work around construction obstructions and weather delays.

GPRS is a highly experienced team of 3D laser scanning professionals who deliver exceptional service, accurate data, and custom deliverables to expedite your project.

GPRS can quickly mobilize to your site and provide free quotes.

Nationwide Retailer Partners with GPRS for Existing Condition Sewer Assessment
This nationwide retail customer needed to accurately assess the storm and sewer systems of over 700 of their store locations across the United States. A nationwide cctv sewer inspection provider was necessary for consistency and final reports. GPRS performed utility locating, video pipe inspection, 3D Photogrammetry to create a comprehensive map and 2D CAD drawing of the facilities sewer system. This aided in engineers properly being able to assess the property and manage their underground infrastructure.
