Leach Wallace was responsible for the mechanical and electrical designs for the new inpatient tower and emergency department at Franklin Square Hospital Center. The new construction and renovation totaled 316,274 SF. The project consisted of a seven-story, 290,000 SF building addition, largely in the form of a new Emergency Department, a patient tower with a rooftop penthouse and a new 18,000 SF central chiller/boiler plant that serves both the existing hospital and the new addition. The project was completed on time and under budget.
The power plant houses boilers, chillers, generators for normal and emergency power and electrical switchgear. The new addition required new mechanical and electrical systems. The installation of six custom air handling units was required to provide the addition with space conditioning and ventilation. The electrical systems consist of three 2,000-KVA substations, and distribution to serve the patient tower. In addition, the installation of a new 6,000-MW emergency engine-generator plant at the central plant building was to provide the necessary emergency system capacity, with transfer switches, uninterruptible power supplies and panels for distribution.
