R&D Tax Credit for Engineering & Construction Firms
Design-build firms and engineering companies frequently qualify for the R&D Tax Credit. The key is technical uncertainty in the design process — not just routine execution. If your engineers are solving problems that don't have obvious answers, you're likely doing qualifying R&D.
The Distinction That Matters
Not all construction work qualifies — routine execution of established methods doesn't meet the IRS criteria. But engineering and design work that involves genuine technical uncertainty does.
The distinction is this: if your engineers are applying known methods to a standard project, that's routine work. But if they're designing a structural system for unusual conditions, developing a new building approach, or testing a method that hasn't been used in this context before — that's qualifying R&D.
Key insight: The IRS doesn't require that the innovation be new to the world — only that it was technically uncertain for your company when you started. A structural approach that's novel to your firm qualifies, even if another firm has done something similar.

Real-World Examples
Novel Structural System
A design-build firm is hired to construct a building on a site with unusual soil conditions. The structural engineering team evaluates multiple foundation approaches, designs a custom system, models it under various load conditions, and iterates on the design based on geotechnical testing results.
WHY IT QUALIFIES
Technical uncertainty (would the foundation system work?), systematic process (multiple approaches evaluated, iterative design), technological in nature (structural engineering). Qualifying R&D.
Energy-Efficient Building Envelope
An engineering firm develops a new building envelope system to meet aggressive energy performance targets. The team tests multiple insulation configurations, evaluates thermal bridging solutions, and iterates on the design based on energy modeling and physical testing.
WHY IT QUALIFIES
Technical uncertainty (could the performance targets be met?), systematic experimentation (multiple configurations tested and modeled), technological in nature (mechanical/thermal engineering). Qualifying R&D.
Custom Prefabrication System
A construction company develops a proprietary prefabrication system for a specific building type. The team designs the component geometry, tests assembly methods, evaluates structural connections, and iterates based on prototype testing.
WHY IT QUALIFIES
Technical uncertainty (would the system achieve the required structural performance and assembly efficiency?), systematic process (design, prototype, test, iterate), technological in nature (structural engineering). Qualifying R&D.
