Our construction quality control programs typically include our strong daily presence on the jobsite. Our field technicians maintain contact with project managers and the client representative through daily reports and weekly status reports. We are typically responsible for certifying compliance with shop drawings; measuring quantities of pay items; auditing survey data (line, grade, and quantities); computing quantities; monitoring yields and overseeing field adjustments; performing and managing materials inspection; inspecting workmanship; preparing directives, change orders, and supplemental agreements; preparing periodic/final payment estimates and reports; confirming materials/equipment tests; coordinating off-site inspection services by others; analyzing construction contractor claims if any, and maintaining photo record of construction. Our laboratory technicians provide testing in accordance with ASTM, AASHTO, ATM, and WQTEC testing standards for soil and concrete. Our laboratory is certified by US Army Corps of Engineers to conduct a wide variety of soil, concrete, aggregate, and grout testing. We can provide both ACI certified concrete and NRC certified nuclear equipment field technicians. The laboratory maintains nuclear densometers, concrete field sampling equipment and laboratory concrete strength testing equipment. In addition, we maintain triaxial strength testing equipment, permeability testing equipment, and consolidation testing equipment for non-routine soil testing.
