Two disciplines,one agency, one record.

Special inspection happens on site, while the work is being built. Material testing happens in the laboratory, on samples taken from that same work. Projects usually need both, and running them under one agency means one schedule, one point of contact and one set of records that reconcile with each other.

We name the method, not just the service.

A report that says "concrete testing" tells a reviewer nothing they can check. A report that names the governing method tells them exactly what was done, to what procedure, and what the result should be compared against — which is what the engineer of record, the building official and, if it ever comes to it, an expert reviewing the file years later actually need. Naming the method also disciplines the work: an inspector who has to cite the procedure has to be performing it.
