RFI NO. 01 PROJECT: REPLACE ROOF & BRICK REPAIRS 110A

LOCATION: HVAMC 100 Emancipation Dr.

DATE: 05/17/2018 Hampton, VA 23667

TO: VAMC COR, A/E

TDSC PROPOSAL NO: 0606

ATTENTION: Mr. Keith Norman REQUESTOR: Darren Bryan, PM

DRAWING REFERENCE: AE400 POSSIBLE COST IMPACT: ☒ YES ☐ NO

SPECIFICATION SECTIONS: 01 32 16.15 & 02 41 00 POSSIBLE SCHEDULE IMPACT: ☒ YES ☐ NO

REQUEST RESPONSE BY: ASAP

REQUEST:

1) To utilize a PE for shoring design, will the VAMC be able to provide additional info related to the current design loads of the roof structure, or the current roof framing plan? This information should be available under the As-Builts for Bldg. 110A. If possible, could the VAMC share any additional information with bidders?

2) Sheet AE400, Wall Section Detail 5 shows designed shoring to be installed above the finished ceiling height in the mechanical room (56 courses above new work Datum). Could the VA please provide more information with how we are to access the space above the mechanical room and below the finished roof.

3) Additionally, are we to price the shoring and bracing per the drawings? We are unable to determine if this will be the final product until stamped by the PE. This must occur post award, so we are to bid the system per the drawings and significant changes to the initial design would come as a change?

4) Sheet AE400, Note 11 calls for the contractor to provide 1” insulated off-blank panels for the louvers. This note is shown as Typical. Should the contractor assume this work will also occur at the Louver Modules located on the East Elevation

5) Additionally, Sheet AE400, Note 2 calls for the contractor to remove & discard of the sealant and debris to expose the edge of through wall flashing on the entire elevation as indicated by the dashed line. Can the contractor safely assume this work note is not typical for the South & East Elevations?

INFORMATION (CONT)

RFI NO: 01

6) Sheet AE400, Note 2 – What is the intent for having the contractor remove the sealant from the through wall flashing around the structure perimeter? The Drawings do no indicate we are to replace through wall flashing at these locations

7) Sheet AE400, Note 2 – The drawings do not specify any new work notes associated with this work note.

Are we to replace the through wall flashing in the areas indicated by the dashed line? If so this will require brick removal along the dashed line shown.

8) Could the A/E provide a section cut for the tie in of new brick to existing? A detail for tie in was not provided in the contract drawings. Currently the Brick veneer is flush with the existing CMU. Once the cavity wall is added per sheet AE400 the depth will change and the new brick will no longer be flush with the existing from above and NE Elevation. Please advise.

9) 01 32 16.15, Section 1.6, Subpart D. This section implies that we are to account for Asbestos Abatement in our cost per work activity. It is unclear what may need to be abated unless a survey is provided prior to commencement of work. Please provide an Asbestos Inspection report if we are to consider Abatement as part of the Base Bid.

10) 02 41 00 Section 1.2 Related Work: D. Asbestos Removal: 02 82 11 – This section is not provided within the specifications. E. Lead Paint: 02 82 33.13 – This section is not provided within the specification. If it is the intent to include any form of Abatement under this contract, please provide an Asbestos and Lead Paint Inspection Report.

11) What equipment is being fed from the junction box shown on Sheet AD101, Quadrant 8E? This service will need to be interrupted during demolition.

12) Confirming that we are not providing any form of lightning protection under this contract? Would the VAMC like for us to include lightning protection as a Bid Option under this solicitation?

13) Could the VAMC confirm the locations where we can utilize a laydown area for a dumpster?

14) Will the VA restrict access to the entrance so we are able to drive a forklift and crane up to the building?

15) Will there be any noise and fume restrictions due to the proximity of the OR?

RFI NO: 01

RESPONSE:

1. Design loads and roof framing plan are unavailable.

2. Mechanical room is accessible from fifth floor of the main hospital.

3. The shoring shown on the drawings represents a general schematic of what needs to be shored and states maximum spacing requirement to safely complete the project. The contractor shall retain a professional engineer to design a shoring system to temporarily support the brick wall during construction activities. The shoring shown on the drawings is a general schematic that utilizes a cantilever design. The contractor’s professional engineer may present a number of alternative, acceptable shoring methods.

4. Typical only at west elevation; east louvers are beyond scope of project.

5. Correct; AE400, Note 2, only applies to north and west elevations.

6. The sealant prevents moisture from leaving the wall cavity at these loactions; within the scope of work.

7. Through-wall flashing to remain; remove sealant and repair mortar.

8. Per as-built drawings provided by VA Hampton, and selective demolition, the existing conditions illustrated on the construction documents provide accurate information. New brick is tied into an existing brick veneer cavity wall. CMU is the backup for the veneer and never “flush” with the face of the brick. Fourteen (14) courses of brick must be cut, in depth, to maintain flush exterior, as noted in Wall Section 5/AE400. The cut brick runs the full length (+/- 13’-4”) of the field of work indicated on North Elevation 7/AE400.

9. Asbestos Abatement is not included in this project.

10. Asbestos Abatement is not included in this project. Section 02 82 11, Traditional Asbestos Abatement is not included.

11. This will be determined during construction.

12. Ligtning protection is not to be included. This will be addressed later.

13. Laydown location will be within area near the building entrance. Specific location to be determined after award.

14. Due to there being the two doors which are paths of egress from the building in the project vicinity, these doors must remain accessible for egress out of the building. Overhead protection must be installed over these paths of egress.

15. We do not anticipate the systematic removal of brick, in a controlled fashion, to produce excessive noise. However, if construction operations cause excess noise, this will be an issue and will need to be mitigated.
