General Contractors
The specification calls for testing, the subcontractor says the work is complete, and the owner will not accept handover without documentation. That sits with you.
So does the sequencing. Envelope testing has one window before the cladding closes. Roof testing has to happen before overburden goes down. Concrete has to be scanned before anyone cores it. Each of those is a day, and each one is a day that stops several trades if it lands in the wrong place.
What we run for you
Electronic leak detection
Certifies a new membrane before sign-off without flooding the structure or waiting on weather.
Air & vapor barrier testing
Verifies the barrier while it is exposed, when a failure costs an hour instead of a tear-back.
Concrete imaging & scanning
Locates rebar, post-tension and conduit before cutting, which is cheaper than the alternative by several orders of magnitude.
Building envelope testing
The wider envelope scope where a project specifies more than the barrier alone.
What you get
Documentation that closes the specification item, dated and located, in a form the owner and the architect will both accept.
Close-out testing is delivered against the standard the specification names, whether that is ASTM D7877, D8231, E1186 or D4541, with documentation the architect accepts.
Questions we hear from general contractors
The spec requires ELD at close-out. What do you need from us?
Access, the membrane complete, and the test before overburden goes down. One mobilization, the day coordinated with your sequence, and the documentation lands in the close-out package.
What happens if the test finds a breach?
It is marked on the roof and the plan the same day, the sub repairs it while the crew is still mobilized, and the retest closes it out. Found at close-out it costs an hour; found by the owner it costs a claim.
Can you scan a slab before we core?
Yes. Rebar, post-tension and conduit are located and marked ahead of the cut. Against the cost of hitting a tendon, the scan is not a line item worth debating.
