Reality Capture and Infrastructure Mapping at a Historic Courthouse

• Built in 1936 and last updated in 1957, the courthouse is a designated historic property that required state approval for renovation under New Mexico’s preservation laws
• Renovations were needed to expand office space and upgrade public-facing facilities to meet departmental growth
• The architect needed to document the aging infrastructure, including boiler room, plumbing, electrical panels, and elevators in need of replacement
• The building footprint was complex, spanning 5 floors and 70,000 square feet, including a basement and three roof sections
• There were no up-to-date records of the building’s layout and infrastructure, which complicated design coordination and increased construction conflicts

‍

• GPRS scanned the block surrounding the courthouse using ground penetrating radar to locate & map underground utilities, including electric, communication, gas, water, sewer, irrigation, and unidentified lines
• Four 4'x4' concrete areas in front of elevators in the building were GPR scanned to assess slab conditions and detect embedded features such as rebar and conduit
• Full-color 3D laser scans documented the courthouse’s interior, exterior, and roof structures, capturing all architectural, structural, and MEP components, as well as field markings from utility locating and concrete scans
• Scan data was converted into detailed 2D CAD drawings and Architectural/Structural & MEP 3D Revit models
• All maps, drawings, and models were securely uploaded to SiteMap®, GPRS’ cloud-based GIS software platform

‍

• The architect received accurate records of the building’s layout and infrastructure, minimizing guesswork and reducing construction risk
• Utility markings and concrete scan data helped to prevent costly strikes, structural damage, and delays during future work
• Captured data facilitated upgrades, space planning, and maintenance across all five floors
• The comprehensive above and below-ground documentation available 24/7 in SiteMap, guided safe renovations, streamlined maintenance, and will inform planning for the life of the historic building
