Owner Bid Questions

VA Bid Questions:

1. The purpose of this memo is to respond to questions from the Bidders on the above mentioned Project.

VA Comment: HDG Response:

Question #1: Add VA comment – Add “Superintendent cannot be changed out without 30-days written notice and approval from the Government.”

Question #4: The Government’s current chemical supplier is MIS-America; however, the current contract has no provisions to include the Cooling Towers and will ultimately need to be re-solicited. Bidders are advised to use whichever Vendor they are comfortable with.

Question #19: Evaluation Factor #2: References to Patient Aligned Care Team (PACT) have been changed to utility plant.

Question #20: Glycol Tie-in Procedure: Question is confusing – there are no existing chilled water systems that we are connecting to. Contractor shall provide adequate glycol to system such that system is prevented from freezing down to -20°F.

Question #23: Do Details B1/ MP501 and B2/MP502 apply to the hallway? Should this be noted?

See Spec 230541 Noise and Vibration Control for HVAC Piping and Equipment. Piping in hallway shall be per detail B4/MP501.

Question #25: Evaluation Factor #2: No. CPARS evaluations cannot be submitted in lieu of Past Performance Evaluation Questionnaire.

Please see added note on GI001 Cover Sheet, under heading “Contractor Notes.”

Add Onyx Workstation for Fire Alarm System at Room 7- 108 (Electrician’s Shop).

Please see added note on GI001 Cover Sheet, under heading “Contractor Notes.”

The Project that will relocate the surge tank has been delayed and will likely not be bid until Chiller Project is underway. This Contractor will have to maintain tank and pumps as shown on the plans until the other Contract can be awarded. That Project will advise the Bidders that they will be required to coordinate all work with this Contractor.

Please see added note on GI001 Cover Sheet, under heading “Contractor Notes.”

Sheet AD102 – Remove and replace western Kalwall System in Detail #1; HDG: Consider keeping some of the mezzanines to maintain access to the storage space above the offices as well as next to the Northern stair tower.

Kalwall replacement is Alternate 1.

Sheet AE 105 – HDG: not crazy about Keynote #11. Can’t we keep part of the mezzanine so we can maintain access to this room?

As discussed on 09/02/2020, the mezzanine needs to be removed to allow for the chillers and related piping.

Sheet AE 201 – Where the generator exhaust stacks (note

13) and the remote radiators (note 11) removed? Also, what about the exhaust fans (note 12) associated with the former generators.

HDG: We had reviewed an alternate pipe route at the one meeting, but it we have never seen sheets to reflect.

Is this other route still an option?

The current drawings reflect the best possible pipe routing, which was modified per the August 2019 site visit.
