All questions received by the due date and time will be answered in an amendment to the solicitation as soon as practicable after the due date and time. Any questions received after the due date and time will not be addressed through any Amendment.

4. Please confirm we are to assume that there are no contaminated or hazardous soils to be removed from the project.

a. The Government does not confirm that contractors are to assume that there are no contaminated or hazardous soils to be removed from the project.

5. Sheet CS.1 General Note #6 references 01010 for a list of permits the Contractor needs to obtain. We did not see a specific list or permit provided. Please provide

a. General Note #6 should reference section 011100 rather than 01010; this is a typographic error only and does not otherwise change the requirement. Section 011100 establishes the responsibility of the Contractor to obtain and maintain permits where required. No permits are required of the Construction Contractor at the time of this solicitation to complete the work as designed. The requirements remain in effect should unforeseen or differing site conditions arise that encumber different permitting requirements in the future.

6. Is the lighthouse currently leaning out of plumb?

a. The lighthouse was not surveyed for lean or plumbness during the design phase and therefore NPS has no objective metric by which to evaluate or respond to this question. At this time there is no requirement in the contract documents to alter the alignment of the lighthouse.

7. Please confirm an owner’s office is not required.

a. No, an owner’s office is not required.

8. Where is the location of water and 120v electric per C.12 in the Solicitation (page 9/64).

The solicitation, part C.12 article (c) states the following (emphasis added by NPS in this response): “WATER, AND ELECTRICITY: Water and 120V electricity may be available at no cost to the contractor, depending on the location. Should water and electricity not be readily available, the contractor shall provide these services as needed to perform the required work.” Water (potable and non-potable) and 120V electricity are not readily available on-site. The Offeror must provide these services as needed to perform the required work.

9. Specification 040120.64 Brick Masonry Repointing calls for the brick pier masonry joints (Bid Item 7) to be measured and paid by the LF instead of SF. Please correct on bid form.

a. The bid form is corrected for bid item 7.

10. Do the brick masonry piers require general cleaning and paint removal? Please confirm they do not require new paint.

a. Yes, brick masonry piers require general cleaning and paint removal This requirement is established on Sheets D3.1 and D3.2; the demolition note in legend states to “remove existing paint at masonry piers” where indicated by diagonal hatch. NPS confirms no new paint shall be applied.

11. Please confirm extent of masonry work is the installation of the (4) new precast plinths per detail 3/S5.1 and repointing of the brick piers.

14. Is all paint required to be removed from the interior and exterior surfaces prior to repainting or just to sound paint (i.e. not flaking)?

a. Sheets A1.1 and A3.1 keynote <PT-2> establishes the requirement to “PREP SURFACE, PRIME, AND PAINT.” There is no absolute requirement to remove all existing paint down to bare wood; the performance requirement is to prepare the wood for successful priming and subsequent top-coating.
