TSIT Engineering & Consulting

What TSIT Engineering & Consulting does

TSIT Engineering & Consulting, LLC is a Texas-headquartered professional services firm founded in December 1993 by Terry Smith, Sr., a former Southwestern Laboratories Asphalt Laboratory Supervisor, that delivers geotechnical engineering and construction materials engineering and testing (CMET) services. The firm operates out of three Texas locations — its headquarters at 11301 Mosier Valley Road in Euless with a 7,000 sq ft AASHTO- and TxDOT-accredited laboratory, a second 7,000 sq ft accredited laboratory in the Dallas/Fort Worth area, and a 3,000 sq ft accredited facility in Leander in the Austin market — supported by project managers averaging 25 years of CMET experience and technicians averaging about 10 years.

The company delivers seven interconnected service lines: Construction Materials Testing (field and lab concrete, aggregate, and rebar testing), HMAC Engineering & Testing (TxDOT Dense Graded, SMA, and Superpave mix designs, plant inspection, laydown observation), Geotechnical Engineering (subsurface exploration, foundation design, embankment stability, pavement engineering), Masonry Inspections, Roofing and Waterproofing, Forensic Investigations (including expert witness support), and Specialty Testing such as Relative Humidity (ASTM F2170) and Calcium Chloride (ASTM F1869) floor moisture testing. The firm is TxDOT administratively qualified in both material and geotechnical engineering, holds AASHTO lab accreditation in North and Central Texas, and is certified as a DBE, MBE, SBE, and HUB business.

TSIT generates revenue through project-based, quote-based professional services engagements billed to municipalities, state agencies (TxDOT, NTTA, Trinity River Authority), airports (DFW International, Alliance, Dallas Love Field), commercial developers, healthcare and education institutions (Parkland Hospital, TCU), sports venues (AT&T Cowboys Stadium, American Airlines Center), and banks. Customer acquisition is through direct field outreach, government vendor registrations, professional referrals from engineering and architectural sub-consultant relationships, and an active portfolio presence on the company's website. There are no signs of outside institutional capital, M&A activity, or platform-style technology adoption — the firm operates as a stable, founder-led LLC in the Texas infrastructure services market.
