Civil & Infrastructure Engineering

Civil infrastructure and utility work require engineered, PE-stamped plans for permitting and compliance. Cen Tex Engineering delivers these plans efficiently—our familiarity with Central Texas municipalities and utility providers means fewer revisions and faster approvals.

Water/Wastewater (W/WW) Tap Plans

Connecting to municipal water and sewer systems requires engineered tap plans that meet the specific requirements of the local utility provider. Our tap plans include site plans, tap location details, connection methodology, utility clearances, and the PE stamp required for approval.

We regularly prepare plans for Austin Water, as well as utility providers in Waco, Belton, Temple, Killeen, Round Rock, Cedar Park, Georgetown, San Antonio, and municipalities throughout our coverage area. Our familiarity with each provider's submission standards means your plans are prepared correctly the first time—avoiding the revision cycles that delay permitting.

Site, Grading & Drainage Plans

We prepare engineered site plans, grading plans, and drainage plans for residential and commercial projects. These plans address stormwater management, finish floor elevations, positive drainage away from structures, and compliance with local grading requirements. Whether you're developing a lot or managing drainage for a complex site, we deliver permit-ready plans with fast turnaround.

Topography Plans

Accurate topographic surveys and plans are the foundation of good site engineering. We prepare topography plans that document existing ground conditions—critical for grading design, drainage analysis, and retaining wall layout on sloped and challenging sites throughout Central Texas.

Impervious Cover Calculations & Reports

Many jurisdictions in Central Texas cap the percentage of a lot that can be covered by impervious surfaces. We prepare accurate impervious cover calculations and reports required for permit applications—ensuring your project stays within allowable limits and passes plan review without delays.

Lot & Home Purchase Feasibility Studies

Thinking about buying a lot or an existing home for development or renovation? We provide feasibility studies that evaluate the structural and civil engineering constraints of a property—soil conditions, drainage, impervious cover limits, setbacks, and utility availability—so you know what you're getting into before you close.

Traffic Control Plans

Any work that affects traffic flow on a public roadway in Texas typically requires a Traffic Control Plan (TCP) compliant with the Texas Manual on Uniform Traffic Control Devices (TMUTCD). Our plans include site diagrams, signage layouts, channelizing device plans, flagging operations, and detour routes as needed.

We produce TCPs for utility work, construction projects, lane closures, and special events. Plans are stamped by a licensed PE and prepared to meet TxDOT and local municipality requirements.

Temporary Structure Engineering

Event stages, shoring systems, scaffolding, and other temporary installations often require structural engineering and a PE stamp for permitting and safety compliance. We provide structural analysis, design, and stamped plans for temporary structures—whether it's a concert stage, construction shoring, or specialized scaffolding.
