The scope of work involves the comprehensive replacement and upgrade ofthe HVAC system for the Main Facility Building. This includes the installation of new HVAC equipment, replacement of rooftop units, and improvements to the air distribution system. Major components of the project include the replacement of the cooling tower, air handling units (AHUs) in the north mechanical core of Building E, and Liebert units in all IT rooms throughout the campus. The project may also require renovations or expansions to accommodate the new mechanical equipment, as well as minor interior finish repairs. To facilitate the installation of the new AHU in Building E, a new penthouse will be constructed on the roof. This penthouse will be built using lightweight insulated metal panels and will require extensive structural analysis to maintain the integrity of post-tensioned tendons during demolition and construction. Roof penetrations will be minimized to preserve structural integrity with the existing post-tension structural system. The plumbing scope of work includes rerouting existing roof drainage and vent systems to accommodate the new mechanical layout. A sprinkler system will be installed in the new penthouse, and existing sprinklers in the mechanical rooms will be adjusted to fit the revised ductwork configuration. Electrical upgrades will be performed as necessary to support the demolition and installation of the new HVAC equipment. This includes providing new conduits, wiring, and disconnects for all replaced equipment. Fire alarm systems will be enhanced with the addition of new devices where required, and lighting, power, and controls will be installed in the new penthouse. A load study will also be conducted to confirm that the existing electrical infrastructure can support the increased load from the new equipment. While the project is expected to involve minimal abatement based on selective testing conducted during the design phase, all necessary precautions and adjustments will be taken to ensure compliance with project requirements. Environmental report can be provided for additional information. The existing building structure is post-tension which limits the placement of openings and extra weight.
