Williams (Phyllis E.) Elementary - 16.050 - Prince George's County Public Schools

The scope for the new work is to replace the eight (8) constant volume air handling units, sixteen (16) existing hydronic cabinet unit heaters, forty-eight (48) VAV terminal boxes and the hydronic piping system. The air handlers, unit heaters, VAV boxes and piping systems are at the end of their usable life and require replacement. The existing VAV boxes are bypass type terminal boxes not capable of having the existing controls retrofitted to DDC controls. The new terminal boxes shall be variable type units. With exception of the multipurpose room, all other air handling units shall be variable type units for energy efficiency. Piping replacement shall also include replacement of all four (4) distribution pumps. Destructive replacement of the existing four-pipe hydronic system will require replacement of the suspended ceiling and lighting. New lighting fixtures shall be LED type fixtures. The project is included in the 2023-2028 capital improvement plan (CIP). As of September 19, 2022, further details regarding design and construction have not been identified.* *Project information has been obtained through a public capital improvement plan (CIP).
