PM Insight

Deliverables

GPRS provided the client with intensity map point cloud files (.RCS files) and AutoCAD 2018 files (.DWG files). The 3D model included basic structural elements, such as exposed structural columns and joists, grade and canopy. With the 3D model, the following details could be used to execute prefabrication - elevations, plan dimensions, radii of rolled elements, plus locations and dimensions of all attachment hardware.

PROJECT APPLICATION

TASK

GPRS provided 3D laser scanning services for six parking lot structures at the Dallas Fort Worth International Airport, ranging from 500 to 2,500 square feet in plan area. The client wanted accurate dimensional information to prefabricate replacement canopies for each of the structures.

Task

GPRS provided 3D laser scanning services for six parking lot structures at the Dallas Fort Worth International Airport, ranging from 500 to 2,500 square feet in plan area. The client wanted accurate dimensional information to prefabricate replacement canopies for each of the structures.

PROBLEM

The client needed accurate information to design replacement fabric panels, including the location of the attachment plates and fasteners. They requested a quick turnaround on this project, GPRS expedited deliverables within 15 working days of the purchase order.

Solution

Dimensions were quickly verified in these high traffic areas of the airport with a Leica laser scanner. GPRS’ Mapping & Modeling Team created an LOD 200 Revit 3D model including basic structural elements, such as exposed structural columns and joists, grade and canopy. With the 3D model, the following details could be used to expedite prefabrication and installation - elevations, plan dimensions, radii of rolled elements, plus locations and dimensions of all attachment hardware.

Benefits

An accurate point cloud and 3D model was critical for verifying field dimensions to fabricate replacement canopies. 2D shop drawings can be created with the 3D model building annotation to prefabricate panels. Prefabrication of the panels eased installation, saving resources, time and money.
