A commercial builder shaped by experience, accountability, and a better way to deliver construction.

RADIX is a full-service commercial general contractor headquartered in Nampa, Idaho, serving clients across the country. We help owners and developers move from early opportunity through design, pricing, construction, turnover, and stabilization with one clear objective: protect the client and deliver a successful asset.

Built to lead the entire construction journey.

RADIX was incorporated in July 2003. Since then, the company has grown from a regional contractor into a licensed and credentialed team capable of supporting commercial projects in 40 states.

Our work includes ground-up construction, tenant improvements, remodels, multi-site programs, and complex projects delivered through traditional bid-build, pre-construction, design-assist, design-build, construction management, negotiated GMP, and open-book contracts.

The delivery method may change. Our responsibility does not: lead the process, protect the client, and create the clarity required for good decisions.

Long-term operators. Owner-led accountability.

Nick Downing and Jeff Giddings have been part of RADIX since 2013. After years of helping lead and grow the company, they purchased RADIX in October 2022 and began its next chapter as active owner-operators.

Nick serves as President and Jeff serves as Vice President. Their leadership is grounded in the work itself: planning projects, building teams, solving problems, managing risk, and remaining accountable to the client from the first conversation through final delivery.

RADIX is not managed from a distance. The owners are engaged in the business, the projects, and the outcomes.

Where we work.

RADIX serves commercial clients across multiple project types, including retail, restaurants, education, healthcare, industrial and flex, office, mixed-use, multi-family, public work, and pre-engineered metal buildings.

Our Nampa headquarters keeps us rooted in the Treasure Valley. Our systems, licensing, and relationships allow us to support clients well beyond Idaho.

The project should be protected before the problems reach the field.

Construction outcomes are shaped early. The quality of the scope, budget, design coordination, procurement plan, schedule, and delivery system determines what happens later.

That is why RADIX does more than price drawings. We help clients understand the project, test assumptions, identify risk, create options, and choose the delivery path that best supports their goal.

Honesty is the currency of trust.

Recognition and relationships.

RADIX has built its reputation through repeat relationships, demanding schedules, complex project requirements, and teams that expect real accountability. The strongest proof is not a claim on a website. It is the clients who invite RADIX back and the teams who trust RADIX with the next project.

Tell us what you are trying to build.

You do not need complete drawings to start the conversation. If you are evaluating a site, testing a budget, developing a design, or deciding how to buy the construction, RADIX can help you understand the next right step.
