COMMENTS

Comment: B300 AC Replacement – Do the power requirements for the AHU and condensers need to be the same as existing?

Reply: No. Voltage available in the mechanical room is 480v and 120/208v. There is breaker space and capacity available for both options.

Comment: B300 AC Replacement – Where can the condensate for the Comm Room split units go?

Reply: Provide a proposed condensate line path as indicated in the submittal requirements.

The closest existing plumbing for Room 6 is located in the group of bathrooms/kitchen in rooms 15, 16, and 17. The closest existing plumbing for Room 32 is room 34 (elec/mech room). All ceilings are accessible drop ceilings. The contractor will be responsible for condensate pumps or any other additional equipment needed for their proposed condensate line path.

Comment: B300 AC Replacement – There is an existing government owned genie lift in the mechanical room. Is this available for contractor use?

Reply: No. The contractor is responsible for all equipment and tools to execute the work unless specifically stated in the Statement of Work.

Comment: B300 AC Replacement – Is there existing Glycol in the hot water coil in AHU #1?

Reply: No, the existing mixture is water and a chemical inhibitor for corrosion.

Comment: B300 AC Replacement – What does the existing ductwork below AHU #1 feed?

It may need to be removed to access it.

Reply: The ductwork below AHU #1 is the return duct to that unit. Any piping, ductwork, supports, or any other equipment moved or damaged to gain access to AHU #1 will be reinstalled or replaced by the contractor.

Comment: B300 AC Replacement – Can we see a wall section of the back wall of the mechanical room?

Reply: Please see attached. Refer to detail 2, A2.5 and detail 8, A4.3.

Comment: Repair Lift Station Pumps and Controls – Is there a curb stop or another method of isolating the pump station down stream?

Reply: No, there are existing valves located in the pump station to isolate each pump individually.

Comment: Repair Lift Station Pumps and Controls – The existing sump pump in the pump station was removed by maintenance personnel. The pump model is Zoeller M57-0001.

Nameplate power information is as follows: 3hp, 1ph, 115v, 9.7a. Replace as indicated in the Statement of Work.

Comment: The specification call for the replacement of both Condenser Units, but when going through my configuration tool, the AHU Specified only requires the one condensing unit for the design. Please clarify on the need for two condensing units with the new package.

Reply: The government has changed requirements for the condenser replacement. The new model number to match equivalency is YD360C00A2BAA2. This is a single 30 Ton, York Millennium Split System R-410A Air conditioner, 4 Pipe, 4 stage cooling, 208/230-3-60 Smart Equipment Controller and includes a HACR circuit breaker/disconnect sized for 208 volts.

Field and factory installed accessories include Low Ambient Kit (208/230V 30T, model # 2LA04713925), and a Hot Gas Bypass Kit (model # 2HG04700824). Bidders may submit alternative models/manufacturers that meet the performance (cfm, heating/cooling capacities) of this unit, and that have equivalent accessories. As stated in the SOW, the contractor will be responsible for modifying the existing condenser supports for the replacement condenser.

10 Comment: Three different equipment vendors concur, that the combination of tonnage between the AHU, and the condensers is not a combination, which will work. The AHU is 15 ton, and the two ACCUs are a combined 25 tons. Vendors will not quote, based on the current schedule, despite the statement in Addendum 1. If the air handling equipment is 15 tons, then the ACCUs should be no more than a combined 15 tons. Please advise.

Reply: The government has changed requirements for the air handler replacement. The new model number to match equivalency is ND360C00N6AAA1. This is a single 30 Ton, York Millenium split System R-410A Air Handler 208/230/460-3-60, 4 Pipe air handler with drain pan. Field and factory accessories include Standard Static Drive (model # 1LD0407, contains sheave and belt), Motor Overlad Relay Kit (model # 2MP04708700), and a 2 row deep hot water coil (model # 1HW0406). Bidders may submit alternative models/manufacturers that meet the performance (cfm, heating/cooling capacities) of this unit, and that have equivalent accessories. As stated in the SOW, the contractor will be responsible for modifying the existing condenser supports for the replacement condenser.

Comment: B300 AC Replacement - Although AHU #1 does not currently supply cooling, it is still operational, supplying heat and ventilation to half of the building. It is the government’s desire to minimize the downtime between demolition of this unit and the installation of the replacement.

Comment: B310 Water Damage Restoration – Who is responsible for moving furniture in occupied areas where carpet cleaning/restoration is to occur?

Reply: The Contractor shall be responsible for moving any furniture to facilitate work included in the project contract documents.When work has been satisfactorily completed the Contractor shall move the furniture back into the rooms in the original location. Computers, phone lines, Ethernet cables and any other equipment that is unplugged in order to be moved for the cleaning shall be plugged back in by the Government and not the General Contractor or subcontractor.

The Government requests that the contractor develops and submits a cleaning schedule that takes advantage of the building being minimally occupied each Monday.

Comment: B300 AC Replacement – Replace both split unit AC for comm rooms with Mitsubishi PKA-A12HA6 (indoor) and PUY-A12NHA6 (outdoor), or equivalent. Outdoor units must contain Wind Baffles for low temperature (0ºF) operation. Wall mount units as indicated in project drawings.

Comment: B300 AC Replacement – See attached for as-builts for the DDC temperature controls for B300 (from 1992).

15 Comment: B300 AC Replacement – Included in the installation of the new Air Handling Unit is the balancing of the HVAC system. Several existing VAV controllers are inoperable in the building. Work with the COR on balancing airflow in these areas.

16 Comment: Can the air handling unit/existing condensers be replaced with an outdoor packaged unit?

Reply: Yes. Bidders may submit an alternative proposal. A proposed outdoor package unit would need to meet all of the heating, cooling and airflow requirements intended in the statement of work and within the addendums. The contractor shall be responsible for any and all system requirements (gas, hot water, refrigerant etc.) for a complete and functional unit.

IMPORTANT – Final bids will not be evaluated based on an alternative proposal. Bids will be awarded based on the cumulatative CLIN prices (all base bids and bid options together).
