Building 534 is a four-deck facility with north and south wings, housing approximately 230 birthing rooms. The first deck additionally contains two large adjoining laundry rooms, three potential office areas, two public restrooms, a conference room area, and lobby space. Three main stairways provide building access located on the north, center, and south sides—with ventilation ductwork in these areas also requiring inspection and cleaning.

This building underwent renovation in 2012, and the corresponding mechanical drawings from that renovation are included in the bid package to help contractors locate units and quantities.

Project logistics and staffing arrangements include:

• Laydown Area: Location will be determined during the Pre-Construction meeting, if required.

• Personnel: A single individual may serve as Site Superintendent/SSHO/QC Manager for the project duration, provided they possess all proper qualifications and training for each position. The Government does not provide any training for the positions stated above.

• Safety Protocol: All energized equipment must be properly locked out/tagged out (LOTO) and de-energized prior to commencement of any work activities.

• Access: The engineering technician will work closely with building managers to create a schedule for access to all rooms and roofs for contractors to complete their work.

• Alarms/Sensor: The engineering technician will coordinate any deactivation of alarm or sensors if applicable.

• Filters: No filters will be supplied by the Government; all existing filters should be cleaned and reinstalled. Any screen filters or pleated filters that are deemed end of life should be itemized and noted in daily briefs. Once duct cleaning is completed, an itemized list of filters needing replacement will be given to the Navy to coordinate replacement.
