Integrated Architecture & Engineering in Oklahoma

Most contractors hand design to an outside firm and inherit the coordination gaps. TCG runs architecture, structural engineering, and MEP engineering in-house, so design intent and constructability are reconciled before drawings are finished, with Oklahoma wind loads, storm shelters, and expansive soils designed in from the start.

That integration is the core of design-build. Paired with preconstruction and value engineering, it delivers code-compliant design that is priced and buildable, and compresses the overall schedule by 15 to 30 percent versus design-bid-build.

FAQ

Architecture & Engineering FAQ

What is design-build?
Design-build combines architecture, engineering, and construction under a single contract. Overlapping design and construction delivers projects 15 to 30 percent faster with fewer change orders.
How are architecture and engineering fees structured?
Architecture and engineering fees are usually a percentage of construction value, commonly 8 to 15 percent combined for commercial work. In design-build, those services are bundled into one contract. See our guide to A and E fees and soft costs.
Is your design team licensed in Oklahoma?
Yes. TCG provides architecture and engineering licensed in all 50 states, including Oklahoma, and we design to Oklahoma code and ASCE 7 wind requirements.
Why is in-house A and E better than outsourcing?
In-house architecture, structural, and MEP reconcile design intent with constructability and budget before drawings finish, which removes the coordination gaps that cause change orders.
Do you design for tornadoes and expansive soils?
Yes. Our structural engineers design ASCE 7 wind resistance and ICC 500 storm shelters, and drilled pier foundations for central Oklahoma's expansive clays.
Can you bid from our existing plans?
Yes. We work from owner-provided drawings as a general contractor and also provide full in-house design when you need it.
