# Question Answer 1 After completing a more thorough review of the drawings and specifications, it appears this project is designed for onsite construction. Will you accept off-site wood frame permanent modular construction built to the same building codes as an alternative delivery method? This methodology will allow for less disruption (people, material deliveries, and equipment) to this very sensitive cultural site, it will also provide better quality control and schedule improvement resulting in lower GCs and earlier use of the facilities.

Yes, both on-site and off-site construction is acceptable

2 Have you considered opting for a modular building as oppose to stick-built? We believe we could be a vital solution that offers you the most for your time and money.

Yes, both on-site and off-site construction is acceptable

3 Will on-site (dry) camping (in RVs) be permitted? Yes, no more than 10 people will be allowed to camp at site. Space will be limited.

4 Please confirm the Government will provide archeological monitoring.

Yes, Govenerment will provide archeological monitoring

5 Assuming proper notification and coordination, when artifacts are encountered and work is stopped, will the project schedule be adjusted? Will the contractor have any recourse for stand-by or shut-down time?

Yes, the project schedule will be adjusted if these activities follow within the critical path

6 Please confirm if water will be available on site. Contractor shall supply own water for construction. Limited potable and non-potable is available for personal use.

7 Modular or panelized building construction was mentioned on the site visit. How should offerors proceed to ensure all are bidding to the same specifications?

Specifications allow for both options to build on-site or off-site.

8 What is to be done with any contents or furniture remaining in the buildings to be demolished?

All remaining furniture and material will be apart of the demolition efforts of the contractors

140P2025R0078, CHCU 310250, Q&A as of 8-22-2025

9 Can the SSHO and QCM positions be "double hatted"? Yes, the superintendent shall be a separate, full time, on-site postion. The site safety specialist and quality control specialist can be the same person if they carry both certifications.

10 The Building Material Hazard Survey identifies asbestos in the 12 x 12 vinyl tiles only in the furnace closets of Buildings 7, 10, and 11. It was observed on the site visit that a wood flooring overlay was installed in all of the buildings. This overlay was likely installed on top of existing vinyl tile which was not tested. Please advise

Please assume vinyl tile is under wood flooring overlay in all units.

11 Is the existing building demolition to be included in CLIN 1—Site Work?

Yes.

12 It was discussed at the site visit that the cultural monitor is not in the general contractor’s scope of work. Please confirm.

Please confirm if you are referencing a cultural monitor or an archeological monitor. Both archeological and cultural monitors not being required by the contractor. Govenerment will provide archeological monitoring

13 Under spec section 01 50 00 – 4, article 2.2.B, it includes details for a Contracting Officers field office and states “Field office shall be a separate structure from Contractor’s office.” Does the government want the contractor to include a separate office for the Contracting Officer in its scope or is the government to provide and maintain this Contracting Officer’s field office?

The Governement field office will be provided by the contractor for the use of the on-site Construction Management Representative (CMR) and government personel when on-site for site visits.

14 Under spec section 01 11 00 – 3, article 1.5.H, it details permission for the contractor to establish a “Construction Camp” in the Park Staff Area. At the site visit, this topic was discussed and the government clarified it was still looking at the details. Please clarify if a construction camp will be allowed for the contractor and if so, to what extent will staff be allowed to stay onsite? Will it be only the contractor’s field supervision team or will subcontractors be allowed to camp onsite as well? Will RVs/campers be allowed?

Yes, no more than 10 people will be allowed to camp. Personal use water is available at the existing Mission 66 housing. Campground near site has a dump station for personal use. Space will be limited. Contractor will be required to contact electrical service provider for temporary electric service paid by the contractor.

15 Under spec section 01 50 00 – 1, article 1.3.B, it states “Water Service: Potable Water from existing water system is available for use without metering and without payment of use charges. Provide connections and extensions of services as required for construction operations without any additional permit costs.” At the site visit it was discussed that it is still unclear if there is water available onsite for construction operations. We anticipate needing thousands of gallons of water per day during earthwork activities. Please clarify if there is a water source available onsite for construction operations and if it has the capacity to meet the needs of construction. Also, if there is a source onsite, is it located within the boundaries of the project or another location within the park? If another location, please provide the approximate distance from the water source to the project site.

Contractor shall supply own water for construction. Limited potable and non-potable is available for non-construction use.

16 The solicitation is requiring resumes for the contractor’s project manager, superintendent, on-site quality control specialist, and on-site safety specialist. With a project of this size, is it acceptable to have one individual assume the combined roles of on-site superintendent, quality control specialist, and safety specialist?

No. The intent is that the PM is an off-site position. The superintendent shall be a separate, full time, on-site postion. The site safety specialist and quality control specialist can be the same person if they carry both certifications.

Please confirm the intent of the project is to provide a modular housing solution?

No, modular design is not proposed. It will be the contractor's responsibility to provide foundation details/specifications submittals for approval if deviating from the provided design. See questions 22 and 23 below

22 If the intention of the project is to provide a modular housing solution in lieu of stick built construction, will the government redesign the foundation to accommodate a modular solution?

No, it will be the contractor's responsibility to provide foundation details/specifications submittals for approval if deviating from the provided design.

23 Will the government allow the contractor to backfill against the modular structure? The Architectural details show a 9" space between grade and the bottom of the wall assembly, but the modular structure will take up most of this space from top of foundation to bottom of wall assembly.

No, modular design is not proposed.

24 The bump out at the front entry of the A unit adds significant cost and complication to a modular solution.

Will the government consider redesigning the unit to remove the bump out and reduce the overall cost to the project? This can be accomplished by extending the plan east wall out to maintain the square footage of the unit and relocating the front entrance to the east as well.

For this soliciation, please match the provided design.

25 Can the existing structure that is not in the rock fall zone be utilized as a construction office?

Once the contractor takes posession of the site, it is their responsibility to conduct work as they assess safety to their work plan. The government will not dictate terms after construction award unless immediate and health and safety and observed per the specifications.

26 Verify that the site is balanced and no import will need to take place and that on-site soils will be acceptable for backfill.

The intent of the design is for the site to have a balanced earthwork scope which requires no import or export of material. On-site soils shall be acceptabl for backfill

27 Confirm that the existing utility connections will be disconnected by NPS before demolition begins?

38 Confirm a passive radon system is acceptable. Follow design specified.

39 Based on the Hazard Assessment, only the exposed floor tiles inside utility closets was noted as having asbestos.

During our site walk of the existing buildings the existing flooring consisted of 2-layers of flooring material as seen between the crawlspace access hatch and floor vents in various rooms. Are we to assume the flooring beneath the exposed "floating floor" is also asbestos tile? Likewise are we to assume all of the texture, drywall and window putty is ACM?

Please assume vinyl tile is under wood flooring overlay in all units.

40 Plan C-2 calls out building #16 which is a brick shed behind building #11 (to be demolished). Building #16 appears to be within the landscape protection area, however it is not noted in drawing C-3 or the C-5 drawing for demolition. Is this building to be excluded from abatement and demolition?

Building #16 is excluded from any abatement or demolotion.

41 The hazard assessment report identified asbestos in window putty and lead in various paints on site. These are precisely the types of materials from an at-risk era that are known to potentially contain PCBs which were typically used in construction during the 50's thru the 70's. PCB's were widely used as plasticizers and for durability in materials such as caulking, glazing, sealants, paints and adhesives used for flooring and tiles. Will the base bid or bid alternate require this EPA regulated material be tested by the abatement sub-contractor for site characterization of these materials prior to abatement?

The window putty tested positive for asbestos and should be abated per the provided specification. Paint tested positive for lead and should be abated per the provided specification. No testing of PCB’s is intended for this project.
