Construction Materials Testing and Inspection

Construction materials testing from Fort Worth, Houston, San Antonio and Dallas regional offices is performed by local staff. Alpha Testing construction materials testing uses in-house staff and equipment, including structural steel and IBC special inspections. Alpha Testing staff hold CWI, ACI, Troxler, NICET, TxDOT and TxAPA designations.

Alpha Testing performs the complete spectrum of construction materials testing (CMT) and inspection services, as well as construction materials engineering (CME). Close coordination with the geotechnical engineering department provides rapid response to field constructability questions.
