Will the government require a transition period between each phase? Assuming there will be a transition phase, how many calendar days will the government require between each phase?

01 00 00 General Requirements G. Phasing:

TWO (2) days between each phase are allowed for users to move equipment out of the next phase. This is subject to Hospital Operational Requirements

002. 4 MAR 2020

On the plans there are multiple items that say that they will be relocated by others, will the government confirm that if a note says it will be done by others, the other is someone other than the contractor?

Yes – the word “others” is someone other than the contractor?

003. 4 MAR 2020

The project duration does not appear to be enough to complete the work considering the specification require the contractor to acquire PIV badges for all employees and the specifications say that the contractor shall allow 4‐6 weeks for badges to be issued; in addition, the submittal process will take at least 30 days after NTP

1.3 STATEMENT OF BID ITEM(S)

A. ITEM I, Base Bid: GENERAL CONSTRUCTION: Replace Operating Room Suites Flooring in Building 500, 5th floor, North wing as indicated on the drawings, specifications and any additional document that may have been provided. Work includes demolition, disposal, general construction, alteration and certain other items. Construction Duration time: 76 Calendar days (page 4) and it will take at least 4 weeks after the submittals are approved to get the materials before we can even start construction. It is safe to say that 60 of the 76 days will be consumed before we even start demolition. Assuming the contractor can work uninterrupted, will the government extend the period of performance to 230 calendar days? This will allow for 60 days to get badges, submittals and materials procured, then 30 days of construction for each phase and 14 days for government transition between each phase plus a few days for inspections and punch list. If the contractor may be interrupted by normal operations or must work limited hours or days, the contract duration could extend out by at least another 30 days.

The construction duration period noted is strictly for construction on the site and must be strictly adhered

to. 30 days for submittals and order/delivery of materials after NTP before on‐site construction is added.

004. 4 MAR 2020

The plans and specification talk about options, yet the RFP bid sheet does not provide for any options. Will the government please provide a bid sheet that list each of the options?

Provide all your bids (base, options, etc) in the same areas you would place a regular bid. These areas are section 17 on the SF 1442, Section A.2 “Price/Cost Schedule” and/or on a separate sheet to be delivered with your bid. There is not a separate “bid sheet” for options.

005. 4 MAR 2020

Note D‐214 on sheet A1.51 states to “remove/replace or reuse the existing Mop sink”, this is in 2 HAC closets. For bidding purposes will the VA please determine prior to the bid due date if the mop sinks need to be replaced as there is a cost involved in replacing the mop sink versus just reusing?

Clarification:

1. Delete the word “or reuse”

2. The VA desires to replace the mop sinks versus just reusing

3. Omit room 5023 from scope

006. 4 MAR 2020

Project Schedule Specification 01 32 16.15‐ part 1.3 Contractor’s Consultant.

Yes ‐ the contractor can utilize a current member of the project team to prepare and update the project schedule.

007. 4 MAR 2020

Quality Controls Specification Section 01 45 00 part 3.2.B.1 indicates that the CQC system manager reports to the project superintendent. This paragraph seems to indicate that a separate QC Manager that is not the project superintendent is required.

Until the proper moisture tests can be performed after the NTP, it is unknown the quantity if any of moisture remediation coating that will be required. Will the VA treat Moisture Remediation Coatings as an unforeseen condition if the existing concrete floor does not meet moisture requirements?

0016. 10 MAR 2020

In specification section 01 00 00 Par 1.2.A is says to “patch & repair, with paint to match existing of any part of the walls damaged as a result of flooring/corner guard replacement operations” and then in the next sentence it says: “Painting of all the walls is included in the scope of work. For paint in Operating rooms and Sterile rooms see Schedule of Finishes.”.

The plans clearly say to repair, patch, prep and paint the doors and door frames, but don’t say to paint all the walls.

Will the Government please clearly state if we are to paint all of the walls within the area we are working or are we to only touch up the walls where we remove the recessed corner guards and patch them with drywall so as to allow for the installation of the surface mounted SS corner guards?

If we are just patch, are we expected to paint from corner to corner or just blend in the paint as best as we can?

Also included is replacement of corner guards as shown on drawings and patch & repair, with paint to match existing of any part of the walls damaged as a result of flooring/ corner guard replacement operations.

Painting of all the walls is included in the scope of work. For paint in Operating rooms and Sterile rooms see Schedule of Finishes. (page 3)

Patch &repair and paint to match existing if wall painting is deducted per deduct alternate.

0017. 10 MAR 2020

On sheet A1.51 demolition note D‐207 says the existing fixed shelves are to be temporarily removed and reinstalled. The note is pointing to one of the three section of the fixed “DSI” shelving units, yet sheet A3r.6 says that these same shelving units are to be uninstalled and disposed of.

Is it the governments intent to remove and dispose of all of these “DSI” fixed shelves or is it the governments intent to remove them and reinstall them? If they are to be removed and disposed of, are we to assume that we are to remove the concrete housekeeping pad that they are sitting on? If they are to be removed and installed are, we to remove and reinstall all the shelves or just the one that the note is pointing to?

Clarification:

Contractor to uninstall and dispose of shelving units. Please follow

SECTION 02 41 00

DEMOLITION for disposal

The existing concrete pads to remain.
