Inspections & Testing

Sign-off shouldn't be the thing that delays you.

A DOB-approved Special Inspection Agency and materials testing lab under one roof — so the inspection, the sample and the report all come from the same team, on the same schedule.

  • Grout and mortar sampling
  • Aggregate verification
  • QC procedures to NYC requirements

TR4

Soil Borings & Geotechnical

Subsurface investigation and certification of conditions, with reports written for construction decisions rather than the shelf.
