The University of New Mexico Chemistry Clark Hall was a remodel that consisted of a system upgrade on HVAC and plumbing from the 1980s on a building created in the 1950s. All the existing HVAC and plumbing was renovated in order to bring this building to optimum performance. Labs were occupied during the remodel process, posing the challenge of protecting ongoing projects and experiments while quickly and efficiently completing the construction. Temporary ductwork was integrated to preserve the building’s functionality throughout construction. Prefabricated ductwork also gave this project momentum to finish on time and within budget. This project has applied for LEED Silver.
