Construction contractors take engineering or architectural designs and turn them into reality. Without the construction piece of a private development or public works project, drawings and specifications have little to no value, which is why the construction industry comprises a large portion of the U.S. GDP each year. While the design team provides general direction to the contractor on a project, showing what the end product should look like and the materials needed to achieve this result, the means and methods are typically left to the builder.

How does a construction company qualify for the credit?
There is a four-part test used to determine whether a company has a project that qualifies for the R&D Tax Credit. If you have a project that meets each of the four quadrants below, your project most likely qualifies.
Technological in nature
- Discover information that fundamentally relies upon principles of Hard Sciences (i.e. Physical Sciences, Biological Sciences, Engineering, Computer Science, etc.)
- Not social, economic, or psychological Permitted Purpose
Permitted Purpose
- Develop a new, or improve an existing, product or process
- Related to Functionality, Performance, Reliability, Quality, Significant cost, Savings, etc.
- Not Aesthetics
Eliminate Uncertainty
- Capability
- Uncertain if able to achieve desired result
- Methodolgy
- Uncertain of optimal design or process to achieve project goals
- Goals to show there were issues and potential alternate solutions
Process of Experimentation
- Evaluate and test alternative design or process to identify optimal solutions
- Methods to use
- Prototyping
- Modeling
- Systematic Process of Trial and Error
- Simulation
- Computer Science Testing (Validation, Beta, etc.)
Once a company determines that their project meets these criteria, three expense categories factor into the tax credit calculation:

Wages
- Employees involved in conducting or carrying out qualified research.
- Employees providing supervision of qualified research.
- Employees providing support for qualified research activities.

Supplies
- Resources consumed or used up during the carrying out of qualified research.

Contract Research
- 3rd parties paid to assist in the conducting or carrying out of qualified research.
- Requires the Company to maintain rights to the project (i.e. research performed on behalf of the Company)
- Requires the Company to bear the expense if the research is unsuccessful.

Mechanical Construction Contracting
Where carpenters and steel erectors build the bones of a building, the mechanical contractor builds the respiratory and cardiovascular system. Building mechanical is a key component for virtually every project that involves any level of plumbing, drainage, or HVAC work. This construction specialty lends itself especially well to R&D tax credit qualification due to the number of new mechanical technologies constantly being offered by vendors. A few examples of qualifying activities that a mechanical contracting company might partake in include:
- Developing scale models for a building mechanical system to analyze a new technology being offered by a vendor.
- Building Information Modeling (BIM) to identify potential conflicts (clash detection) before starting construction.
- Creating a new method for estimating material or construction costs.
- Designing a mechanical system to meet LEED or other energy efficiency standards.
- Experimenting with new piping or ductwork materials to optimize for a given criteria, whether it be energy efficiency or cost.
- Evaluating and improving upon a construction method, such as an improved method to support pipe or ductwork.
