Commercial Architecture & Engineering in San Antonio, TX
Commercial A&E fees run 6–12% of construction cost — and design-build delivery through Terrapin Construction Group compresses that while eliminating designer-vs-builder coordination gaps. Architecture by 3rd Act Architecture, MEP by 9BA MEP, structural engineering, and preconstruction live under one contract, so your San Antonio project is priced as it's drawn. Licensed in all 50 states.

Analyzing Your SA A&E Project
Your SA A&E Cost Estimate
One Contract. Full Design Team. Builder's Pricing From Day One.
Most commercial projects bolt together an architect, three engineering consultants, and a GC who sees the drawings for the first time at bid day. TCG runs it differently: architecture through 3rd Act Architecture, MEP engineering through 9BA MEP, structural engineering, and preconstruction estimating under one design-build contract. The people drawing your building and the people pricing it sit on the same team — which is what a design-build contractor actually does.
Architecture — 3rd Act Architecture
Schematic design through permit sets and construction documents, with constructability and budget checked at every milestone. Architectural design-build services →
MEP Engineering — 9BA MEP
Mechanical, electrical, and plumbing design coordinated with the trades who will actually install it — no clash-detection surprises in the field. MEP engineering →
Structural Engineering
Foundations, steel, tilt-wall, and PEMB systems engineered alongside the architecture, not after it. Structural engineering →
Preconstruction
Live cost models as the design develops, so value engineering happens on paper — where it's cheap — not in change orders. Precon services →
How Much Do Architecture & Engineering Fees Cost in San Antonio?
| Building Type | A&E Fee (% of Construction) | Key Drivers |
|---|---|---|
| Warehouse / industrial | 4% – 7% | Repetitive structure, simple MEP, clear-height engineering |
| Restaurant / retail | 6% – 10% | Kitchen MEP density, health-code review, brand standards |
| Cold storage / IMP specialty | 6% – 9% | Thermal envelope detailing, refrigeration coordination, floor design |
| Medical / lab | 8% – 12% | Code complexity, equipment planning, redundant MEP systems |
Ranges reflect 2026 commercial design fees; San Antonio construction costs themselves run 0.85–0.98x national — benchmark against our commercial construction cost guide — so the same fee percentage buys more building. For deeper benchmarks, see our guides to architectural services costs and value and A&E fees and soft costs.
Why Design-Build Beats Design-Bid-Build in San Antonio
Design-bid-build separates the people who draw from the people who price — and the gap between them is where budgets die. With design-build delivery, projects typically come in 5–10% lower in total cost and 15–30% faster: one point of accountability, value engineering during design instead of after bid day, and overlapped design and construction phases. In a fast-growth market like San Antonio — right-to-work labor 25–35% below union metros and a year-round construction season — that schedule compression converts directly into earlier revenue. TCG runs the same integrated design-build model statewide — see our Austin, Houston, and Dallas commercial GC pages.
Permitting helps too. San Antonio's plan review is fast by major-metro standards (see our state-by-state permitting timeline guide), and because TCG's in-house team produces the permit set, we engineer it to clear review the first time — then manage submittals, comments, and approvals as part of the same contract.

San Antonio Architecture & Engineering FAQ
How much do architectural services cost in San Antonio?
Commercial A&E fees in San Antonio run 6–12% of construction cost depending on building type: 4–7% for warehouse and industrial, 6–10% for restaurant and retail, 6–9% for cold storage and IMP specialty work, and 8–12% for medical and lab projects. Design-build delivery through TCG compresses those fees by eliminating redundant coordination.
What's included in TCG's A&E services?
Full architecture through 3rd Act Architecture, mechanical, electrical, and plumbing engineering through 9BA MEP, structural engineering, and preconstruction estimating — all in-house, under one design-build contract. You get schematic design through permit sets, construction documents, and construction administration from a single team.
Is design-build cheaper than design-bid-build?
Typically yes — design-build projects run 5–10% lower in total cost and finish 15–30% faster than design-bid-build, because the builder prices and value-engineers the design as it develops instead of discovering budget problems at bid day.
Does TCG handle permitting in San Antonio?
Yes. TCG manages permit submittals and plan review as part of design-build delivery. San Antonio's permitting is fast by major-metro standards, and our in-house design team produces permit sets built to clear review without redesign cycles.
Can TCG take over a stalled design?
Yes. TCG regularly takes over stalled or over-budget designs, completing documents through 3rd Act Architecture and 9BA MEP, value-engineering the project back to budget, and carrying it straight into construction under one contract.
Who are TCG's in-house design partners?
Architecture comes through 3rd Act Architecture and mechanical, electrical, and plumbing engineering through 9BA MEP — both integrated into TCG's design-build team rather than contracted at arm's length. Explore our architectural design-build services and MEP engineering pages for full scope details.
What soft costs should I budget beyond A&E fees?
Beyond the 6–12% design fee, budget for permit and plan-review fees, impact and utility fees, geotechnical and survey work, testing and inspections, FF&E, and owner's contingency — typically another 8–15% of construction cost. Our guide to A&E fees and soft costs breaks down every line item.
How fast is permitting in San Antonio?
Fast by major-metro standards — straightforward commercial projects often clear City of San Antonio plan review in weeks rather than months, though complex occupancies like medical take longer. Because TCG produces the permit set in-house, we engineer it to clear review the first time. See how Texas compares in our permitting timeline guide by state.
Does TCG provide structural engineering?
Yes. Foundations, structural steel, tilt-wall, and pre-engineered metal building systems are engineered in-house as part of TCG's design-build scope, coordinated with the architecture and MEP from day one instead of bolted on afterward. See our structural engineering page for capabilities.
What areas does TCG serve in San Antonio?
TCG serves all of Metro San Antonio and Bexar County — downtown, the Medical Center, Stone Oak, the far west side/SeaWorld corridor, and the Loop 1604 and I-35/I-10 corridors — plus New Braunfels, Schertz, Seguin, Boerne, and the broader Austin–San Antonio corridor.
