The Georgia State University Natural Science Center Project includes renovation and upgrade of the laboratory exhaust system. The project entails replacement of all existing utility type fume hood exhaust fans with multiple clustered, manifold type, high velocity exhaust systems and retrofitting of existing fume hood exhaust control system. We will replace 157 chemical fume hood exhaust fans on the roof and manifold the laboratory exhaust system into 10 new variable speed Strobic Exhaust Fans. In addition, we will install new Stainless Steel duct risers and headers. We will install new variable pressurization control valves in all laboratories in the Natural Science Building. The project entails rebuilding and restoring to specified performance the existing three building axial supply air fans. Finally, we will commission and rebalance all new laboratories, laboratory controls, and exhaust fans, as well as, conduct ASHRAE 110 Tests on all 157 chemical fume hoods. The delivery method for the project is CM/GC.
