The IRS Processing Center design-build project encompasses three new buildings with a connected parking garage, a renovation of a historic 1930’s Post Office, an underground tunnel, a cafeteria and commercial kitchen, and a new warehouse. U.S. Engineering was the lead mechanical contractor for the project, directing all design and preconstruction services as well as HVAC and plumbing construction activities. The project and design utilized an energy-efficient approach, which allow for future interior changes and contributed to earning the desired LEED® certification for the project.
