Indianapolis Architecture & Engineering (Design-Build)
Terrapin Construction Group delivers architecture, MEP engineering, and structural engineering for Indianapolis commercial projects under one design-build contract, with construction coordinated from the first sketch.
Most commercial project risk lives in the gap between design and construction. When the architect, engineer, and builder work under separate contracts, coordination errors surface during construction as change orders, delays, and finger-pointing. TCG closes that gap by delivering architecture, structural, and MEP engineering under the same roof as construction, through design partners 3rd Act Architecture and 9BA MEP Engineering.
For Indianapolis owners, integrated design-build means one accountable team from concept through closeout. Constructability is checked continuously rather than after drawings are done, budget is validated against real subcontractor pricing during design, and the schedule overlaps design and construction to shorten the overall timeline by 15 to 30 percent.
That model serves every sector TCG builds in Indianapolis, from industrial and data center to life sciences, healthcare, and hospitality. Whether you need full design-build or engineering to support an existing team, TCG brings national resources and Indianapolis market intelligence to the drawing set.

Architecture & Engineering in Indianapolis: Common Questions
Yes. TCG provides in-house architectural design, structural engineering, and MEP engineering through design partners 3rd Act Architecture and 9BA MEP Engineering, all coordinated with construction under one design-build contract. Design fees generally run 6 to 12 percent of construction cost depending on complexity.
Most project risk lives in the gap between design and construction. Integrated design-build puts architecture, engineering, and construction under one accountable team, so constructability is checked continuously, budget is validated against real subcontractor pricing during design, and the schedule overlaps design and construction to shorten the timeline 15 to 30 percent.
Yes. TCG can deliver full design-build or provide architecture, MEP, or structural engineering to support an owner's existing team, depending on how the project is set up. Preconstruction defines the right structure for your project.
Architectural and engineering design fees generally run 6 to 12 percent of construction cost depending on building type and complexity. Delivered inside a TCG design-build contract, MEP and structural engineering are coordinated with construction rather than billed and managed separately.
TCG designs and builds across every commercial sector in Indianapolis, including industrial and advanced manufacturing, data centers, life sciences and labs, healthcare and medical office, cold storage, self-storage, and restaurants and hospitality. Each project runs through the same integrated design-build model.
