What TDI Engineering does

TDI Engineering, LLC is a Texas-based, privately held civil and structural engineering professional services firm founded in March 2005 by Jeff Cloyd, Roger Meredith, and Jeff Shindler as Texas Design Interests, LLC and rebranded in 2018 to its current name. The firm provides planning, feasibility studies, design, construction documents, permitting coordination, and construction-phase inspection services for commercial and residential construction projects, spanning site development, land subdivision, and structural design across wood, concrete, steel, and light-gauge-steel framing. The firm also holds specialized expertise in high seismic/wind-zone design, tornado shelters, progressive collapse gravity design, and military and petro-chemical blast design, and offers litigation support/expert witness testimony and quality assurance plan review as ancillary service lines.

The firm operates from two Texas offices — Austin (headquarters, with a newly constructed office building) and Houston/Cypress (with a signed lease to expand by 10 employees and add Civil Engineering alongside its existing Structural Engineering work) — and is licensed as NCEES Registered Engineers in 34 states. The merged entity following the 2019 acquisition of Noble Surveying and Engineering Works employs approximately 30 civil and structural engineering professionals under four principals.

TDI generates revenue through project-based professional services engagements billed on scope and complexity, selling directly to architects, engineers, developers, contractors, and government agencies. The firm markets primarily through its project portfolio website and industry associations, with 92% of clients sourced from repeat business or referrals and 93% of projects reaching completion with no reported structural failures.
