What Construction Testing Services does

Construction Testing Services (CTS), founded in 1994 and headquartered at 2118 Rheem Drive, Pleasanton, California, is a privately held construction testing and inspection firm operating across California and Nevada. The company delivers special inspections (structural steel and welding, concrete, soils, masonry, reinforcing/post-tensioned steel, asphalt, NDT, shoring, waterproofing, and others), materials engineering and testing (laboratory and field testing of concrete, cement, masonry, aggregates, asphalt, and steel to ASTM standards), geotechnical engineering (field explorations, slope stability, seismic evaluations, pavement and environmental studies), specialized engineering (Shotcrete Round Panel, Gamma-Gamma and Crosshole Sonic Logging, GPR, impact echo), and outsourced QA/QC management services. Its customer base spans Caltrans and municipal agencies, hospitals (including OSHPD-governed facilities such as UCSF and Sutter Health), universities, commercial real-estate developers, technology and biotech campuses, water/wastewater utilities, and multi-family projects.

The firm's core technology is elas.™, a proprietary construction technology platform branded as real-time inspection reporting software with a client portal (eolas.cts-1.com). The product description emphasizes instant access to inspection reports, lab results, non-compliance logs, and QA budget tracking — i.e., digitized reporting and project information centralization rather than algorithmic decision-making. CTS also maintains a dense compliance and accreditation footprint (AASHTO AAP, IAS, USACE, Caltrans, ACI, ASNT Level III, AWS, ICC, NICET, NETTCP), which functions as the operational backbone of its delivery.

Revenue is generated through project-based, sales-led engagements: CTS competes for work through competitive bidding and direct engagement with project owners, general contractors, and government agencies; delivers work via resident inspectors and field technicians; and provides an on-call special-inspection consultant relationship with entities such as the City of San Jose (70+ projects). Pricing is not publicly disclosed and is determined per project. The elas.™ platform is characterized in the data as subscription/recurring revenue, though no customer count or ARR figures are disclosed. CTS operates seven offices — Pleasanton (HQ), Oakland, San Francisco, South Bay/San Jose, Sacramento/Rocklin, Stockton/Central Valley, and Las Vegas — supporting regional dispatch across its CA/NV footprint.
