This month’s B2B will focus on a college building program to add dormitory building smoke exhaust systems to serve existing corridors in three four-story buildings. The design intent of the engineered zoned smoke control of the existing supply air system serving the four corridors is to shut the affected supply air damper serving the associated ceiling smoke detector. When a corridor goes into smoke alarm, the new roof-mounted smoke exhaust fan will start and the affected floor’s smoke exhaust air damper shall open providing 20 air changes of exhaust air from the corridor. The alarm signal will also be sent to the campus fire alarm system control center.
The project delivery method shall be construction management (CM) in accordance with Construction Management Association of America (CMAA). The design team shall work with the college’s construction group’s project manager, the campus facility manager, and the college’s fire alarm consultant. The HVAC design engineer will serve as the lead/project manager on a design team that will include the electrical engineering consultant, structural consultant, and in-house college architect. This team, along with the college’s project manager, will work closely with the CM’s project manager and the CM’s estimator and mechanical-electrical coordinator, drawing on the college’s facility group and fire security group as needed.
