Attachment 2 Additional Responses to Questions - Potomac Building 54 Solicitation Amendment 2.pdf

QUESTION Drawing/Reference Responses

Per SOW 1.A.3, Page 1 of 104, it states “roof structure is wood with asphalt shingles roofing system and exterior gutters/downspouts which was replaced in 2019”. Please clarify if just the downspouts and gutters were replaced or the roof and gutters/downspouts were replaced.

Roof, downspouts, and gutters were replaced in 2018/2019.

Please clarify if Building 54 is a Registered Historic Building or not. There is a conflict in the SOW. Per SOW 1.A.2 on Page 1 of 104, it states that "the Department of Labor must initiate consultation with the State Historic Preservation Office (SHPO) to seek a determination of no adverse effect or, if an adverse effect found, to mitigate said adverse effect this project may cause to any "candidate" building or property." Meanwhile Page 4 of 104, Paragraph A.1.b Historic Preservation states "N/A".

Building 54 is not one of the Candidate buildings to be registered on the National Register of Historic Places.

With respect to the Design, please confirm the Design for the entire 1st floor shall be included and completed in Phase 1 and costs included in CLIN0001.

See Scope of Work page 20 section 9.a.1 Confirmed. See SOW Section IV.B.9.a.

For Section B Pricing, CLIN0002 is for Bond Costs to cover CLIN0001. Should we include bond costs for Option Item CLIN 0003 in CLIN0003 or will you be updating this to add a 4th

CLIN.

Fourth (4th) CLIN added to include bond costs if option- CLIN 3 is exercised. Please see attachment.

Has all mold / mildew been removed from the building or will the contractor be required to conduct a Haz-Mat study as part of the D-B SOW?

SOW, I-A.4., page 6/110 Mold/Mildew will be addressed in Amendment #3. A HAZMAT study is not required .

Have the bottom of the walls removed by the previous mold remediation been replaced or are these quantities included in quantities listed in Sections C & E? I-A.4. / Section C, pages 6 / 110 & 28/110 & 73/110 All quantities are included in Part IV, Sections C and E of the Scope of Work.

Are we correct to assume that the Sustainable Design and Building Requirements only pertain to those items being repaired/replaced within the project SOW and not the entire Building Envelope?

SOW, II - Section C-2, page 11/110 Yes. Sustainable Design and Building Requirements only pertain to those items being repaired/replaced within the project SOW and not the entire Building Envelope.

It is our understanding that D-B shall conduct a Seismic Design Review IAW JCH 814. Will repairs be made by the contractor with costs compensation via a contract modification issued by the KO?

SOW, II - Section C-2 & IV - C-14, pages 10/110 & 41/110

Structural repair costs will be compensated via modification if deemed necessary.

Reference to JCH-814 additional design requirements take precedence over the requirements of the contract. Can the Government advise how this statement impacts the project SOW and requirements on this project?

SOW, B. Job Corps Guidelines 1.b, page 10/110 JCH-814 requirements do not take precedence over the requirements of the contract. Where conflicts occur the contractor shall request clarification from the CO, Additional Responses to Questions Solicitation No. 1605AE-24-R-0005 Amendment 2

Currently the solicitation provides no photos, surveys, or assessment reports, on the current conditions of building systems or other elements potentially impacted by water leakage, mold remediation, demolition, or system maintenance outages making the site visit very important. In light of this fact, would the gov't consider extending the period for asking RFIs to 7 days instead of 2 (currently Oct 4th), and extending further for the govt to reply with additional information, and then 14 days from receiving answers so offerors can finalize their design, schedule and cost proposal, ~ 4 weeks extension in total?

Confirmed.

The following statement is included in the last paragraph of B.2 " The Government reserves the right to unilaterally exercise the Option CLIN 0003 within 30 days of the contract award. The completion date shall coincide with the completion date of CLIN 0001."

The documents appear to indicate that the existing electrical panels are to be reused as stated in item c.1). However item a. states that the Contractor shall comply with JCH 814 and provide load calculations for compliance with the National Electrical Codes. If the load calculations determine that the existing electrical service is inadequate and require modifications or replacement will the Government issue a Contract Modification to the D-B for the additional costs to be incurred for Design and Construction?

SOW, Section 1-A.10 & Section 15. Electrical, pages 7/110 & 42/110

The SOW indicates that the distribution panel and down stream panels are to remain. However, load calculations must verify the new and existing loads are not exceeding the rating of the panel.
