TL;DR

Construction and engineering companies innovate daily; designing custom systems, solving field challenges, and testing new methods. These activities often qualify for the R&D tax credit, yet most firms never claim it. This guide explains which construction and engineering projects qualify, what expenses can be included, and how to claim the credit safely and strategically.

Innovation Happens on Every Job Site

Whether you’re a design-build contractor, civil engineer, or architectural engineer, your work likely involves:

  • Developing and testing new building methods.
  • Creating models or prototypes before full deployment.
  • Solving unique site or structural challenges.
  • Integrating energy-efficient or sustainable materials.

These efforts are not “routine.” They are exactly the kind of technical experimentation the IRS rewards through the R&D tax credit.

Why the R&D Tax Credit Applies to Construction and Engineering

The IRS defines qualified research as activity that:

  1. Has a permitted purpose: Improves a product, process, or technique.
  2. Eliminates uncertainty: Addresses unknowns about design, performance, or capability.
  3. Involves a process of experimentation: Uses testing, modeling, or analysis to find solutions.
  4. Is technical in nature: Relies on engineering or physical sciences.

Construction and engineering projects hit these points constantly, especially when they involve custom solutions or new methods.

Examples of Qualifying Activities

1. Design-Build and Engineering Projects

  • Developing innovative framing or support systems.
  • Designing HVAC, plumbing, or electrical systems for unique conditions.
  • Testing seismic or wind-resistant structures.
  • Modeling alternative site layouts or load paths.

2. Construction Methods and Materials

  • Experimenting with precast vs. cast-in-place components.
  • Testing new concrete mixtures or composite materials.
  • Developing installation techniques for modular systems.
  • Reducing waste or improving energy efficiency.

3. BIM, CAD, and Simulation Work

  • Creating or refining 3D building models.
  • Running clash detection simulations and redesigning based on findings.
  • Iterating virtual prototypes to resolve uncertainty before construction.

4. Field Problem-Solving and Site Challenges

  • Modifying designs mid-project due to soil, drainage, or environmental conditions.
  • Engineering temporary structures or supports to test feasibility.
  • Redesigning for code changes or space limitations.

5. Sustainability and Green Building Innovation

  • Designing LEED-certified systems or energy-saving structures.
  • Testing new insulation, glazing, or HVAC technologies.
  • Experimenting with renewable materials or passive-energy strategies.

If your firm is designing, testing, or re-engineering a process to solve technical challenges, chances are you’re performing qualified R&D.

What Expenses Qualify

The R&D tax credit allows you to include several categories of costs tied to those activities:

  • Employee wages for engineers, architects, designers, or project managers involved in experimentation.
  • Supplies and materials consumed during prototype or test builds.
  • Third-party contractors performing qualified technical services.
  • Cloud or software expenses for modeling, CAD, or simulations.

The key is connecting these costs to specific R&D activities, something specialists like B10 Capital help document clearly and defensibly.

Common Misconceptions in the Industry

  • “We just follow plans, we’re not doing R&D.”
    → Even following plans often involves re-engineering or adapting designs to real-world conditions.
  • “Construction isn’t technology.”
    → The IRS considers engineering, physics, and material science as technical fields.
  • “We didn’t invent anything new.”
    → The credit covers improving existing processes, not just creating new inventions.
  • “We didn’t keep perfect records.”
    → Reasonable documentation (drawings, models, time estimates) is usually sufficient.

The Financial Impact

For mid-sized construction and engineering firms, R&D credits often range from $50,000 to several million dollars per year.
Benefits include:

  • Dollar-for-dollar tax reduction.
  • Retroactive claims— can often capture credits for recent past years.
  • Cash flow improvement to reinvest in staffing, equipment, or bidding.
  • Competitive edge—firms that claim credits can price more aggressively without cutting margins.

How Documentation Works in Construction & Engineering

Because these industries don’t keep “lab reports,” documentation usually relies on:

  • Project files, blueprints, and change orders.
  • Time tracking for design and engineering staff.
  • Emails, memos, or meeting notes showing problem-solving steps.
  • Test results or prototype data.

B10 Capital’s process often extracts this information directly from job files and project managers, making it non-disruptive and fully defensible under IRS review.

Why CPAs Often Overlook Construction R&D

Generalist CPAs may view construction as too “routine” for R&D qualification. But most projects involve technical uncertainty; soil conditions, new materials, site constraints, or custom mechanical designs.

Without industry-specific expertise, many advisors under-claim or miss the credit entirely.
That’s why working with an R&D specialist who understands construction workflows leads to larger, safer returns.

Multi-State Projects: Don’t Miss State-Level Credits

Many states, like Texas, California, Florida, Massachusetts, and Utah, offer additional R&D incentives. Construction and engineering firms working across states may qualify for multiple state-level credits in addition to the federal one.

B10 Capital tracks eligibility in every state that offers R&D programs, ensuring clients receive the maximum available refund at both federal and state levels.

How B10 Capital Supports Construction & Engineering Firms

Our specialized approach ensures every qualifying project is captured while minimizing burden on your team:

  1. Industry-specific analysis of design, engineering, and field activities.
  2. Data extraction from existing project files, when possible.
  3. Defensible documentation aligned with IRS standards.
  4. Collaboration with your CPA to integrate credits seamlessly into filings.

The result: maximum value, zero stress, and total compliance.

Final Thoughts

The construction and engineering industries are full of innovation, from design-build experimentation to on-site problem-solving. Yet most firms never connect that innovation to the R&D tax credit.

By identifying qualifying activities, documenting them properly, and claiming both federal and state credits, companies can turn everyday ingenuity into meaningful cash flow.

If your firm designs, engineers, or tests new construction methods, you may already qualify for the R&D tax credit, whether you’ve claimed it before or not.
