Hospitals are some of the most demanding mechanical projects there are. The systems keep patients alive, code review is strict, and much of the work happens inside buildings that never close. New towers, central plant replacements, and tenant improvements in occupied wings all need crews and project teams who know healthcare.
In most buildings, HVAC and plumbing are about comfort. In a hospital they are part of patient care. Air pressure keeps germs in or out of rooms, piped gases go straight to patients, and the systems can never all shut down at once.
Isolation rooms run negative so contaminated air stays in; operating rooms and protective rooms run positive so outside air stays out.
Oxygen, medical air, vacuum and other gases are piped to patient rooms and surgery, and every system is tested and certified before use.
Chillers, boilers, pumps and air handlers are usually backed up so one failure does not interrupt patient care.
Hot water temperatures, recirculation and water management plans control Legionella in a building full of vulnerable people.
Oxygen, medical air, nitrous oxide, nitrogen, carbon dioxide, vacuum and WAGD piping, zone valve boxes, alarms and outlets, installed by ASSE 6010 certified installers and verified by a third party before patients use them.
Domestic hot and cold water with recirculation and thermostatic mixing, water management for Legionella control, sanitary and vent, acid waste for labs, grease waste for kitchens, and specialty fixtures for patient rooms, surgery and sterile processing.
Central plants with chillers, boilers, cooling towers and pumps; chilled water, heating hot water and steam distribution; humidification steam; and N+1 redundancy so a single failure never takes down patient care.
Air handlers with high-efficiency filtration, positive and negative pressure rooms, airborne infection isolation rooms, operating rooms with laminar flow diffusers, and the air change rates set by ASHRAE 170.
Steam and condensate for sterilizers and kitchens, RO and purified water, and piping for imaging and lab equipment.
DDC systems that monitor room pressures, temperature and humidity in critical spaces, with alarms tied to facilities staff.
ICRA barriers, negative-pressure work zones and shutdown planning so construction never puts patients at risk.
