What Noble Surveying & Engineering Works, LLC does

Noble Surveying & Engineering Works, LLC operates commercially as TDI Engineering, a full-service civil and structural engineering firm headquartered in Houston, Texas, with a second office in Austin. Founded in 2007 and operating with approximately five employees, the firm delivers civil engineering design (commercial and multifamily site plans, residential platting) and structural engineering design (ranging from small additions to large-scale construction), along with additions, renovations, full-scale rehabilitation, and quality assurance plan review. Its professional staff serves a horizontal mix of clients including architects, engineers, developers, contractors, and government agencies.

The firm's technical offering is conventional professional engineering services: project-based design and inspection work produced by licensed engineers rather than a software platform or proprietary product architecture. Its documented differentiator is multi-jurisdictional reach, with professional engineering licensure in 70 states. Publicly disclosed portfolio projects include Hyatt Place Houston, Aloft Garza Ranch, Yew Tree Assisted Living, Eastwood High School, NACCU Brownsville, and Warminster, spanning hospitality, senior living, education, and residential/commercial real estate.

The business model is project-based professional services revenue, billed against the scope of each civil or structural engagement. Go-to-market is direct sales and referrals rather than digital marketing, with the firm reporting that 92% of clients are repeat clients or referrals, 93% of projects are taken to completion, and 100% of buildings designed remain standing. Marketing is conducted primarily through the website portfolio rather than paid channels, and the firm operates exclusively in the United States with physical presence concentrated in Texas.
