We test new slabs against the project's flatness and levelness specification and report the results independently of the party that placed the concrete.

Method: F-number testing (FF/FL) under ASTM E1155, supplemented by laser-scan heat maps of the full slab.

Timing: Flatness numbers are typically measured within about 72 hours of placement, so we schedule around your pour calendar. Tell us your pour dates early.

You receive: A pass/fail table by test section, a full-slab heat map, flagged zones in rack and equipment areas, and a short memo comparing results with the specification.

Who hires us: General contractors who want a defensible record, owners' reps checking the contractor's numbers, and operators verifying a slab before fit-out. 

Ground movement monitoring (InSAR)
Satellite radar measures millimeter-scale changes in ground elevation across an entire campus, without instruments on site.

Before purchase: Years of archived satellite data show whether the parcel and its surroundings have been subsiding. In California, that is often tied to groundwater pumping, which connects directly to the water side of the decision.
After construction: Quarterly or annual updates show settlement trends across buildings, pads, and surrounding ground, so problems appear early.
You receive: A deformation map, time-series charts at points of interest, and a plain-language summary of rates and trends.
Limits: InSAR measures the ground and exposed surfaces such as roofs and paving, not interior floors. Anomalies should be confirmed with field survey.
