Pierce Associates has been successfully providing mechanical construction services to the greater metropolitan Washington, DC area since 1961. Known as one of the most prominent mechanical construction firms in the area, our annual volume of work has often resulted in a national ranking among the top mechanical contractors by ENR (Engineering News Record).

Unlike most others in the industry, Pierce Associates performs the full range of mechanical construction functions with our own forces including sheet metal, steam fitting, plumbing, air & water balancing and commissioning for HVAC and plumbing systems.

As a result, we offer both Owners and General Contractors one source for comprehensive performance of mechanical work. This significant advantage results in a smoothly run project and a more carefully coordinated final product.

Pierce Associates maintains a highly trained work force entirely comprised of skilled union tradesmen, insuring a workforce consisting of the highest quality craftsmen. In addition, we have an experienced management team which includes several licensed professional engineers.

Located just outside the Nations Capitol in Alexandria, Virginia, Pierce Associates has performed mechanical construction for virtually every type of project: from basic office buildings to the most complex hospitals, laboratories and semiconductor facilities; from condominiums and hotels to the White House; from subway stations to one of the largest office buildings in the world (over 3 million square feet). Over five hundred projects since 1961... each posing a unique challenge and each successfully completed. These projects have earned Pierce Associates the highest reputation for quality, integrity and reliable performance.
