Answer 8: Yes the buildings will be occupied. The answers to the rest of the questions are listed in SECTION 01 11 00 in the construction specifications.

Question 9: The specifications state that schedule changes require a minimum of 48 hours’ notice to residents. Should the contractor provide resident notices directly, or will notices be coordinated through the Contracting Officer’s Representative / National Park Service?

Answer 9: They will be notified by NPS when the contractor lets us know the schedule.

Question 10: Please confirm whether the existing roofing system has a known manufacturer, installer, or active warranty holder. If an active warranty exists, please provide the available warranty information.

Answer 10: Existing roofs do not have an active warranty.

Question 11: Amendment 0002 states that the Government does not have a hazardous material report. However, Section 02 82 13.21 references a representative report for estimating purposes related to asbestos likely found in wet patching materials around roof penetrations. Please confirm whether any representative asbestos or lead testing documentation is available to offerors.

Answer 11: Representative report attached for asbestos (Attachment No. 09). Lead is assumed on existing paint.

Question 12: Amendment 0003 states that lead abatement is part of the contract if lead is found and that offerors should bid as if lead paint is present. Please confirm whether this applies to all painted surfaces disturbed by the work, including fascia, drip edge, downspouts, and any adjacent surfaces impacted by roofing operations.

Answer 12: Lead is assumed on all painted surfaces, if it is disturbed during construction it needs to be treated as lead.

If any permits or approvals will be handled by the National Park Service, please identify them.

Answer 14: There are no construction permits required on Federal property. If there are OSHA or safety requirements for HAZMAT work, the contractor is required to follow all applicable laws and regulatory procedures. See SECTION 01 35 23 of the construction specifications.

Question 15: Are any third-party inspections, testing, air monitoring, final clearance inspections, manufacturer inspections, or special inspections required beyond the contractor’s own quality control and the Government’s inspection rights?

Answer 15: Testing needs to follow the requirements outlined in SECTION 01 35 23. All final inspections can happen via the contractor and Government.

Question 17: Are there any specific landscaping, soil, mulch, plantings, irrigation, or ground surface restoration requirements for areas affected by access, staging, ladders, scaffolding, dumpsters, or material handling?

Question 18: Should offerors include all applicable California state and local taxes in the proposal price, or is the project exempt from any taxes that would normally apply to materials or construction work?

Answer18: Federal government is tax exempt.

Question 19: Please confirm if the eaves are intended to be painted with the fascia? Or does the scope only intend to repaint the fascia board and drip edge?

Answer 19: Fascia and drip edge, eaves are not included.

Question 20: Regarding the painting of new pipe collars and vents, standard practice is to spray the bottom over the seams and fasteners with spray foam, then to spray over the entire vent with the silicon topcoat for uniformity which would not require the collars/ vents to be painted. If the pipe collars and vents are to be painted, we need to know how high up the vent/ collar to stop the silicon so the remaining vent/ collar can be painted.

Answer 20: The vents need to match the color of the previous vents, as these are historic buildings. The vents need to be sealed and water tight, so the silicon can come up to the point of being sealed and the rest needs to be painted. The purpose is for historic aesthetic.
