Seattle Architecture and Engineering
TCG provides in-house architectural design, MEP engineering, and structural engineering under one design-build contract, designed for Washington's seismic and moisture requirements and built by the same team.

Seattle Architecture, MEP, and Structural Engineering Under One Contract
Most Seattle owners hire an architect, then an engineer, then a contractor, and spend the project mediating between them. TCG collapses that into one accountable team. We provide in-house architecture, MEP engineering, and structural engineering, then build the project ourselves under a single design-build contract.
That integration matters most in a market like Seattle, where Seismic Design Category D, marine-climate moisture, and 8 to 20 week SDCI permitting all have to be designed for correctly the first time. When the people designing the structure, the mechanical systems, and the envelope are the same people building it, the conflicts get resolved on paper instead of in the field. See our preconstruction services.
What Do Architecture and Engineering Cost in Seattle?
Architecture and engineering fees are typically expressed as a percentage of construction cost and vary by project complexity. In a design-build model, these services are integrated with construction, which reduces total project cost by eliminating redesign, coordination gaps, and change orders.
| Project Type | Seattle Cost Range |
|---|---|
| Architectural design (% of construction) | 6-12% |
| MEP engineering (% of construction) | 3-6% |
| Structural engineering (% of construction) | 1-3% |
| Full design-build A/E (integrated) | 8-15% blended |
| Preconstruction / feasibility | Project-based |
Design-build integration typically lowers total project cost versus separate design and construction contracts by reducing redesign and change orders. Use our AI estimator above or schedule a call.
Why TCG for Seattle Design-Build
Single-source accountability is the entire point. With TCG, one team owns the design, the structural and MEP engineering, and the construction, so there is no finger-pointing when something does not line up. The design is constructible because the builders helped draw it, and the budget is real because the estimators were involved from day one.
In Seattle specifically, our team designs every project for Seismic Design Category D and the marine climate from the start, and our familiarity with City of Seattle SDCI keeps permitting moving. Design-build compresses the schedule 15 to 30% versus the traditional design-bid-build path, which in a high prevailing-wage market translates directly into labor savings.
Seattle Architecture and Engineering FAQ
Common questions about architecture, engineering, and design-build delivery in the Puget Sound region. See our full FAQ page for more.
Yes. TCG provides in-house architectural design, MEP engineering, and structural engineering, and then builds the project under a single design-build contract. One team owns design and construction.
Architectural design typically runs 6-12% of construction cost, MEP engineering 3-6%, and structural engineering 1-3%. In an integrated design-build model these blend to roughly 8-15% and reduce total project cost by eliminating redesign and change orders.
Design-build compresses the schedule 15 to 30% and removes the coordination gaps between separate design and construction contracts. In Seattle's high prevailing-wage market, a shorter schedule directly reduces labor cost, and fewer change orders protect the budget.
No. TCG provides architecture and engineering in-house, so you can start from a concept. We also build from existing plans as a general contractor if your design is already complete.
TCG's structural engineers design every project for Seismic Design Category D, and the team designs for the marine climate's moisture demands from the start. Getting this right in design prevents expensive corrections during construction.
Yes. TCG's team is familiar with City of Seattle SDCI and the surrounding King, Pierce, and Snohomish County jurisdictions. SDCI permitting can take 8 to 20 weeks, and design-build helps keep the overall schedule tight.
