RFQ 36C25518Q0166

RFI 1:

After reviewing the wage determination, I believe that this is a construction contract not a service contract. This is not maintaining a unit this is replacing one. This falls under the definition of construction. Please address why you listed this not under the Davis Bacon Act.

This will be a service contract. There are no changes, additions, or up-grades being made to facilities structure. This is primarily the replacement of the existing AC unit.

RFI 2: Please provide a mechanical plan showing the unit so that piping and duct connections can be verified.

Attached H8, H9 and H10

RFI 3:What is the specification on the mechanical insulation for duct and piping?

See attachment: HVAC Pipe Insulation

RFI 4: What is the specification for the piping material and fittings?

See attachment: Piping Materials

RFI 5: What is the specification on the electrical division?

AC 21 is currently fed from BEP1 (Motor Starter) and will be refed re-piped (In hard conduit) to panel BEQ1, located in CB03 on the south wall. BEQ1 is a 200 amp 208 volt 3 phase GE panel fed from ATS- EQ3 DB. I have verified plenty of space available in the panel, although contractor will need to provide breakers for AC21 installation sized accordingly to needs of new equipment.

RFI 6:Please provide a drawing on DDC controls for this unit if this is to have such controls included.

None Available
