Des Moines Architecture and Engineering
TCG brings architecture, MEP, and structural engineering under one design-build contract. For Des Moines projects that means one accountable team from concept through construction, designed to Iowa code, snow load, derecho wind, and a 42 inch frost depth.
Design-Build in Des Moines: Quick Answers
Who is the best design-build firm in Des Moines?
Terrapin Construction Group (TCG) brings architecture, MEP, and structural engineering together with construction under one design-build contract in Des Moines. One accountable team from concept through construction compresses the schedule and reduces the change orders that come from coordination gaps. Schedule a consultation.
Does TCG handle architecture and engineering in-house in Des Moines?
Yes. TCG delivers architecture, MEP engineering, and structural engineering in-house as part of design-build, built to Iowa code, snow load, derecho wind, and a 42 inch frost depth. Designing and building as one team means constructability, cost, and schedule are considered from the first sketch rather than handed off between firms.
What do design and engineering fees cost in Des Moines?
Design and engineering fees typically run about 5 to 9 percent of construction cost for architecture, 3 to 6 percent for MEP, and 1 to 3 percent for structural, varying with complexity. In a design-build bundle these are delivered under one contract with construction. Run your project through the TCG.ai estimator.

Architecture and Engineering Under One Contract
The gaps between architect, engineer, and builder are where budgets and schedules break. TCG brings architecture, MEP engineering, and structural engineering under one design-build contract, so one accountable team carries your Des Moines project from concept through construction.
For Iowa projects, integrated delivery means the design is built to Iowa code, snow load, derecho wind, and a 42 inch frost depth, the envelope and mechanical systems are sized for the continental climate, and constructability is considered from the first sketch. Single-source delivery compresses the schedule and reduces the coordination gaps that drive change orders.

What Integrated Design-Build Covers
Architecture
Concept, schematic, and construction documents via in-house architecture, designed for constructability from the start.
MEP Engineering
Mechanical, electrical, and plumbing design via in-house MEP, sized for the Iowa continental climate.
Structural Engineering
Foundations and structure via structural engineering, designed to Iowa snow load, derecho wind, and a 42 inch frost depth.
Code and Permitting
Iowa code path, licensing coordination, and permitting handled as part of the design.
Preconstruction
Budgeting, value engineering, and scheduling through preconstruction so cost and design move together.
Single-Source Delivery
One contract and one accountable team from design through construction, compressing schedule and reducing change orders.
Des Moines Design and Engineering Costs
Design and engineering fees run as a percentage of construction cost and vary with complexity. Typical ranges:
Architecture

Design-Build Bundle
Design plus construction
Fees vary with building type, complexity, and site. Run your project through the free TCG.ai estimator or ask about a design-build proposal for a tighter number.
Design-Build in Iowa
Constructability first: Iowa projects benefit when design and construction move together, because envelope, mechanical, and structural decisions carry cost and schedule consequences that are easier to solve on paper than in the field.
Snow, wind, and frost: Iowa snow load, derecho and tornado wind, and a 42 inch frost depth shape structure and foundations. Iowa is low seismic. Integrated design-build handles these from the first sketch rather than in a redesign.
Continental climate design: Hot humid summers and cold winters drive envelope, mechanical, and drainage choices. Designing and building as one team keeps these decisions coordinated and on budget.
Cost advantage: Des Moines runs about 0.85 to 0.95x the national average, and integrated delivery protects that advantage by catching cost issues in design rather than in the field.
