The United States is home to some of the world’s most well-respected medical and scientific research facilities. From international pharmaceutical manufacturers to land-grant university laboratories, the country is rich with centers filled with scientists eager to find a solution to some of the world’s most dangerous illnesses or the next scientific breakthrough in nanotech.

What people often overlook, however, is the skill and creativity that constructs these facilities. Laboratories are intricate spaces, and it’s impossible to produce generic ones. The demands of anyone laboratory, in one discipline, in one area of the country, are completely unique. Labs demand varying equipment storage facilities and come with idiosyncratic and byzantine safety requirements.

Given these demands, clients are faced with the challenge of looking for not only the best craftsmen but innovative builders capable of providing unique solutions. This article lists 14 firms which fit that bill. They were chosen based on merit, media presence, experience, and clientele. As you go further down the list, you may notice a good number of these firms are the minds and the muscle behind some of the country’s best facilities.

If you are thinking about building a medical facility or laboratory, we recommend checking each builder’s license with the local licensing board, speaking to past clients, and using our bidding system to get competitive quotes from at least 3 contractors. Getting multiple bids is the best way to ensure you get a fair price and that bids include the complete scope of work.
