PROJECT 460-325 PETTIT GROUP RESPONSES WILMINGTON VAMC ADDITION FOR MENTAL HEALTH (AUDITORIUM INFILL)

# Question Answer

There are plans for Polished Concrete floors, but there isn't much detail provided about them. Could you please provide more information about your expectations for this project.

The rooms that are scheduled with P-CONC as a finish are maintenance type spaces that need a floor that is sealed and dust free and meet minimum criteria as noted in te VA.Til.

2 For rooms 164 and 165D – what is base RMB-1? This has been corrected to read "RB-1"

Drawing I103 - Rooms 164 & 165D – finish schedule & finish box state flooring to be LVT1, however graphic shows CPT1. What is correct flooring? Room 164 is to have CPT-1 as the floor finish. 165 D is to have LVT1 as the floor finish.

Window type A is to match existing; do we know the spec for the existing windows?

A/E does not have the manufacturer's information for the existing window. Wilmington VA should have this information on file from when the project was constructed.

What is the basis of design for window types C and D?

The section detail 2/A501 says to refer to the plan for the window spec, but the plan does not specify anything.

Window types C & D are for the MSA, it needs to slide as shown on the interior elevations, per VA comments. No cutsheets exist. This is a Wilmington VA standard.

Should we assume that Window type B is a hollow metal frame? Window Type B is a HM frame

Document “S02 – Att 05 - Limitations on Subcontracting” references “Construct Community Living Center” in the header of the document, not “Addition for Mental Health”. PCAC: An updated Att05 has been included with the correct project name "Addition for Mental Health"

Drawing I102 – The type “4” sign detail is obscuring the 2nd signage schedule Pettit Group has corrected this issue an will reissue this sheet

Drawings A402, A404, A407, A408, A409 – WC-1? Is this supposed to be AWC-1? Correct - the finish should be AWC-1

Spec. Section 07 27 27 – Fluid Applied Membrane Air Barriers, Vapor Retarding. Please provide more information on where tis is being applied? Is this the same as the polyethylene vapor retarder shown on detail A/S300?

Spec Section 07 27 27 would be applicable where portions of the facades are being infilled. This is not the same as the polyethylene vapor retarder shown on detail A/S300. Refer to attached specification for the polysthlyene vapor barrier.

Confirm that there are no auto door operators included in this project. For reference, the description for door hardware type 12C in spec section 08 71 00 states that

“ALL HARDWARE BY SECTION 08 17 10, INTEGRATED

DOOR ASSEMBLIES AUTO DOOR OPERATOR AND

CONTROLS BY SECTION 08 71 13, AUTOMATIC DOOR

OPERATORS.” However, the description for door hardware type 12C in spec section 08 17 10 doesn’t include door operators. Please advise. Door opertaors are required for this project. Doors 1102 on the first floor leading into the consult room area.

Please provide more information regarding the Deductive Item #1 scope of work: a. Are all interior walls that extend from the Ground Floor to the 1st floor still being demolished? b. Will stairwell 166 be constructed?

c. Will new Ground Floor windows, including window sills (precast and solid surface) and window treatments, still be installed?

Please provide more information regarding your reference to Deductive item #1 (drawings/specifications to which you are referring)

Where in the mechanical room is the tar vapor barrier located that is mentioned in the Hazardous Material Survey Report?

After reviewing the chains of custodies (COC), versus the analysis report for the referenced tar vapor barrier,it was noted that the COC line for 09-18 was blank, so the third-party lab likely assumed that it was ’ditto’ to the previous line for sample 08-17. The main entrance to the mechanical room location appears to be referring to the door caulk 08-17 and 08-16; hence the main entrance description. Vapor barrier located in mechanical room 3092 for sample 09-20 has the positive results (8%). So, 09-19 is inconsequential from a results and location standpoint since it’s homogeneous to the 09-20 sample, which was positive for asbestos. Without seeing the material by being onsite since 2021 we cannot 100% guarantee that the vapor barrier is a black coating on the mechanical room walls. But, from our experiences, a tar vapor barrier is a building material coated on walls and floors and rarely but occasionally on ceilings. The bidding contractors will have to be advised of any black tar vapor barriers in the MER that they have to penetrate for equipment installation or old equipment demo will have to be removed by an abatement contractor prior to impact. The other equipment’s samples all appear as non-asbestos materials. We train our inspectors to specifically identify and describe the materials if it’s on equipment. Vapor barriers are not a mechanical equipment material. But we would not quote that in an RFI. So, in general all black tar barriers found in the MER 3092 need to be addressed as ACM.

Would the lead paint also mentioned in the Hazardous Material Survey Report be considered Lead In Construction?

Yes

Drawing T-501 – Technology Symbols calls for a wireless panic button. The hospital standard is a panic button hardwired into the existing Lenel or Bosch Intrusion System.

Provide hard-wired panic buttons that are compatible with the hospitals existing duress system. (Will need additional information from the owner to provide further direction)

Does the existing Lenel Access Control Panel have room for expansion?

It was assumed there were spare inputs. (Wilmington Technology staff to confirm)

Where inaccessible, such as walls or above gyp board ceilings, conduits shall be provided. Conduits/sleeves shall also be provided at penetrations. EC to provide conduits & sleeves

Solicitation Section 2.13 states “Please be advised that the awardee will need to coordinate with the VA Medical Center concerning badging requirements.” a.

What is the badging process at the VAMC? b. Is there any cost to the contractor associated with badging?

Prime contractors should have PIV badging since they work with the government on multiple projects. Subcontractors and their employees can check in with VA Polcie on a daily basis and be provided with a temporary "DAY BADGE".

Spec Section 01 00 00 1.11C states “A copy of the soil report will be made available for inspection by bidders upon request to the Engineering Officer at the VA Medical Center.” Can the referenced soil report be provided? No Soil Report exists

Is the general contractor responsible to pay for the third-party testing agencies? YES

Are there any restriction to working standard working hours of 7 am to 4:00 pm? NO.

Will the contractor be required to provide site security or is this up to the contractor to provide. NO.

77 Is there a designated location for contractor parking. All Non Lettered POV's shall park on Kirkwood Highway

The specs mention vermiculite whereas the asbestos report does not. We will price only what is identified in the asbestos report.

Please verify that there is no asbestos abatement or Lead abatement required in Phase 4 (room numbers in asbestos report do not match room numbers on drawings).

Any abatement here would have been completed in the earlier phases. Room numbers were changed by the VA in the final submission. This is why room numbers do not match the report.

What are the materials that makes up the existing auditorium ceiling? The existing auditorium ceiling is a combination of GWB and prismatic lenses from our site survey observations.

Will that portion of the existing Ground Floor that will be infilled need any leveling material? The note on drawing AD101 calls out for leveling after demolition. Allow for leveling material as noted on AD101

The new windows on the first floor and along column line P could be used for pumping concrete and for disposal of demolition. If Deduct Alternate #2 is accepted these new opening will not be constructed.

Will it be acceptable to create a temporary opening in the wall for these purposes? Pettit Group has no issue with creating a temporary opening as long as it is approved by the Wilmington VAMC

Are there any materials to be salvaged other than the ductwork, ceiling and lights in the Eligibility and Enrollment Suite?

This questions should be answered by the Wilmington VAMC team as they would know what they intend to salvage and reuse.

Will use of existing stairs and elevator be allowed for workers and materials? NO.

Can Phase 4 demo and construction activities access the first floor using the new stairway? YES

Phase 4, item a. says to relocate the Mental Health Suite to the completed Ground Floor. Will this be done by the VA? If not please provide a detailed scope of work. VA staff will corrdinate the relocation effort.

The Cast-In-Place Concrete Properties Schedule on drawing S001 does not match the design report. The concrete properties indicated on drawing S001 are correct.

Phase 2a, item b says to reinforce all columns outside the work area. Drawing S101 shows only one column to be braced and it is not outside the work area. Please clarify. The drawings are correct. Only column K-1 requires bracing.

It is difficult to remove ceiling grid and tiles without some damage, and replacing some tiles may not match.

Would you consider complete replacement of the ceiling grid and tiles? YES, within reason.

For the relocation of the Eligibility and Enrollment Suite is there any other work in this space other than what is shown on detail 2/G003, described in Phase 2 notes and work required to brace one column?

All required work is indicated on drawings. This phasing plan was reviewed in detail with the Wilmington VAMC team during the development of the design and documentation.

Where will the ACT grid/tiles, lights, diffusers, ductwork be stored? Phase 2 note a. says the Wilmington VAMC to determine. For equal bids this information should be provided.

This questions should be answered by the Wilmington VAMC team as they will know what space is available during this phase.

The notes on detail E/S300 describe the size and depth of the helical piles to use for estimating. Should this be used for the bid? If not, we need he soils report to size the helical piles for the bid, which will be based on an axial compression of 15 tons. The depth of piles should be used for bid. We do not have a soils report for this project.

On Drawing A601, the Window Schedule says that Type A is to match existing; do we know the spec for the existing windows? DUPLICATE

The Aluminum Window specification section 08 71 13, subsection 2.3 A. says to see the SCHEDULE FOR FINISHES on the drawing (I101) for the Basis of Design.

But the “I” drawings do not contain any product information. This information is conatined in the Design Narrative/Report

The section detail 2/A501 says to refer to the plan for the window spec, but the plan does not provide this information. What is the basis of design for the interior windows window types B, C and D? Are these to be hollow metal or aluminum? DUPLICATE

Drawing A601, Window Note 4 states that all glazing is to be blast resistant. Does this requirement apply to all the windows, interior and exterior? EXTERIOR WINDOWS ONLY

Please confirm that ALL wiring associated with the Direct- Digital Controls System for HVAC is to be installed on conduit raceways per the site standard. correct all control wiring shall be in conduit.

Please confirm that the new Direct-Digital Controls System for HVAC is to be an extension of the existing Facilities Explorer by ModernControls building automation system located in the facilities office at the Wilmington VA site.
