Duct Work
Dynamic was invited to bid an engineered project for a 4-story office building in Jericho. This project, a complete HVAC renovation to replace an existing HVAC system that was no longer code compliant. The new system was designed using two 70-ton gas fired rooftop units and a gas fired hot water boiler. The project also included all associated ductwork and hot water piping. This design, seemingly straightforward, brought with it complications and structural considerations. To provide support for the new rooftop units, there was extensive structural steel work involved. There needed to be a 3-hour fire rated boiler room constructed. In addition, shafts needed to be created and space allocated for duct and piping shafts from the roof to the basement. In addition to project cost, these shafts contributed to the loss factor on this building. Then there was an extensive ducted air distribution system including VAV boxes with hot water coils and controls that required a BMS. This design put the HVAC cost well over the owner’s budget. Dynamic was requested to offer an alternate design.
