Case Study: Arden Engineering Constructors achieves almost 90% field labor savings and faster, more accurate as-built HVAC data with Trimble MEP

Arden Engineering Constructors HVAC Mechanical Systems Project Use Trimble Tx6 Scanner & Realworks Office

Arden Engineering Constructors, Rhode Island’s largest mechanical contractor, faced a surge in renovation and retrofit HVAC/MEP work that demanded faster, more accurate as-built spatial data than manual tape‑measure methods could provide. To modernize their workflow they adopted Trimble MEP’s TX6 3D laser scanner and Trimble RealWorks scanning software to capture point clouds for BIM-enabled prefabrication, modeling, and coordination.

Using Trimble MEP’s TX6 and RealWorks, Arden cut field labor by nearly 90%—a biopharma scan that would have taken ~32 man‑hours was completed by one worker in about 4 hours (20 interior and 4 exterior scans over ~4 hours), with each scan taking ~5–6 minutes and delivering <2 mm accuracy at 80 m (extendable to 120 m with an optional upgrade). The faster, more accurate data accelerated ROI (payback estimated after ~4 projects), saved an estimated $10,000 for the contractor, produced 3D as-built deliverables for Revit/Navisworks workflows, and helped Arden secure follow‑on (phase 2) work.
