As-Built Documentation, As-Build Drafting

GPR Data Inc. pioneered the use of ground penetrating radar to create As-Built Documentation for existing construction.

Over time, we have continuously refined and improved this non-destructive service. Older structures and properties often have incomplete records. Newer facilities may lack documentation for specific areas which prove necessary for changes in architecture. From supplemental As-Built Documentation to fill out existing records to the creation of comprehensive plans characterizing every detail, we offer a service fully tailored to your needs. We utilize high-resolution ground penetrating radar 3D imaging to create detailed maps, and deliver this information in the format most suited to your needs, up through 3D/2D to-scale AutoCAD drawings.

One example of As-Built Documentationis Union Station in Portland, Oregon. This historic brick structure dates back to 1902. During a phase of significant seismic upgrades, obstructions were encountered during construction. GPR Data was called in for their expertise in 3D imaging & knowledge of Historic Building Preservation, to create As-Built Documentation of these embedded obstructions.

Roughly 3200 sq ft. of historic masonry brick wall was imaged, analyzed, & output back to our customer in a professionally acquired information database that will be used for multiple phases of seismic retrofitting.
