How TCG Delivers Architecture & Engineering in Middle Tennessee
Terrapin Construction Group runs architecture and engineering in-house through 3rd Act Architecture and 9BA MEP Engineering, plus structural engineering, all under one design-build contract. For Nashville and Middle Tennessee that means a single accountable team from schematic design through permitting, procurement, and construction. The owner is not refereeing a fight between a separate architect, a separate engineer, and a separate GC when the budget gets tight or the schedule slips. One contract, one number, one throat to choke.
Tennessee licensure and local review govern the work. Our architects and engineers coordinate Metro Nashville Codes Department, the relevant suburban authority (Franklin, Brentwood, Murfreesboro, Smyrna, Hendersonville, Mt. Juliet), and the relevant county (Davidson, Williamson, Rutherford, Sumner, Wilson). Tennessee-specific design drivers get engineered in from the start: ASCE 7 wind ratings for the Middle Tennessee tornado belt (the March 2020 outbreak directly impacted Mt. Juliet and East Nashville), limestone karst geotechnical coordination that can shift foundations to drilled piers or micropiles, humid-subtropical envelope and dehumidification strategy, and TVA/NES utility planning for power-dense facilities.
The design-build advantage is most pronounced on technical building types. Medical facilities with med gas, imaging shielding, and Tennessee CON coordination; cold storage with self-performed IMP envelopes; data centers with critical MEP; and cannabis and hemp cultivation with cultivation-grade HVAC all benefit from architecture and engineering that already understands how the thing gets built. We provide architecture, MEP engineering, and structural engineering as a package or individually, and design-build compresses program 15 to 30 percent against design-bid-build.
Nashville Architecture & Engineering Fees and Soft Costs
Commercial A/E fees in Nashville typically run 6 to 12 percent of construction cost depending on building complexity, with MEP and structural as components. Soft costs (A/E, permits, testing, surveys, geotech, commissioning) generally run 15 to 30 percent of total project cost. Use the estimator above for a project-specific range and see the soft cost guide.

Nashville Architecture & Engineering FAQ
Common questions about architecture & engineering in Nashville and Middle Tennessee. See the full TCG FAQ for more.
Commercial A/E fees in Nashville typically run 6 to 12 percent of construction cost depending on building complexity. MEP engineering runs 1.5 to 4 percent, structural 1 to 2.5 percent. Total soft costs (A/E, permits, testing, surveys, geotech, commissioning) generally run 15 to 30 percent of total project cost. Use the estimator above and see the architectural services cost guide.
Yes. TCG runs architecture in-house through 3rd Act Architecture and MEP engineering through 9BA MEP Engineering, plus structural engineering. All can be delivered as a package inside a design-build contract or engaged individually. See architecture, MEP, and structural engineering.
A single accountable team from schematic design through construction. The owner is not refereeing a separate architect, engineer, and GC when budget or schedule gets tight. Design-build compresses program 15 to 30 percent against design-bid-build, locks pricing earlier, and removes the coordination gaps that drive change orders. It is most valuable on technical building types (medical, cold storage, data centers, cannabis).
Yes. While the strongest value is the full design-build package, TCG provides MEP engineering or structural engineering as standalone services for owners and other design teams who need a specific discipline.
Middle Tennessee sits in a secondary tornado belt; the March 2020 outbreak directly impacted Mt. Juliet and East Nashville. Our structural engineers design to ASCE 7 wind ratings (115 to 130 mph for most commercial, escalated for critical facilities), with anchored rooftop equipment, reinforced connections, and shelter-in-place provisions where the building type warrants. This is engineered in from schematic, not added late.
Middle Tennessee karst (sinkhole and void risk) requires geotechnical investigation including borings AND geophysical survey (GPR or microgravity). Our structural engineers design foundations to the geotech report, which may mean drilled piers, micropiles, or rigid mat instead of spread footings. We coordinate geotech early so the foundation design and budget are honest from schematic.
Medical and healthcare, cold storage and food processing, data centers, cannabis and hemp facilities, self-storage, restaurants and hotels, warehouse and industrial, retail, and tenant improvements. Our A/E is strongest on technical building types where understanding how the thing gets built matters. See the Nashville parent page for all sectors.
Schematic design through construction documents typically runs 3 to 8 months depending on building complexity and size, overlapping with permitting and procurement under design-build. Simple TI projects move faster (6 to 12 weeks); complex medical, cold storage, or data center projects take longer. Design-build overlap is what compresses the overall program.
Yes. While site civil is often a consultant scope, TCG coordinates civil engineering, surveying, geotechnical, and landscape architecture as part of the integrated design-build delivery, managing the consultant team so the owner has a single point of accountability.
