Electric service to the residence is on and can be used by the contractor for contract work, subject to the limita ons of the exis ng electrical system service and contract related rehabilita on work on such.

Untreated (non-potable) water is available for project use from four (4) 3,200 gallon storage tanks located approximately 200 feet east of the main house. An underground water service line connects the tanks to the main Dunn house at the rear of the house where the exis ng water treatment system is located. The tanks are filled by a nearby well and require me to refill when used.

Func onal restrooms are not available at the site.

No other u li es are available at the site.

16. Would our Tanzite Stonedecks product (www.tanzite.com) be an acceptable alterna ve to Trex for the decking por on of the project?

From a brief review of the product informa on available publicly, it appears to be a reasonable alterna ve that meets the func on and provides the important features of the basis of design product. If a contractor were to propose it as an alterna ve, the NPS technical reviewers do not see a reason to object.

17. The documents provided on SAM.gov do not seem to include any drawings, with he only technical informa on found in A achment 1 for Scope/Statement of Work. Are any contract drawings included for this solicita on?

Construc on drawings generated for the project are included in the specifica ons

(B08_A achment_1_Specifica ons.pdf) as A achment B, star ng on page 180 of 370. These drawings represent general plan views and profiles of the completed rehabilita on. Site specific plans for proposed interior and exterior building systems are to be developed by the contractor as part of the work.

18. Is the intent for this to be a design/build?

The intent for this project is for the contractor to develop site specific plans for interior and exterior systems covered by the scope of work. This includes but is not limited to: the residen al water treatment system, electrical systems & appurtenances, fire detec on/alarm/suppression systems, HVAC systems, plumbing systems, and the op onal photovoltaic power system. The intent would be for the contractor to provide shop drawings or similar during the submi al process to adequately describe the work. The scope does not include any architectural, structural, or civil changes to the buildings. The intent is to provide the contractor and trade professionals flexibility in the execu on of the scope to maximize value and cost savings.

19. If not Design Build are there any construc on drawings available?

Construc on drawings generated for the project are included in the specifica ons as A achment

B, star ng on page 180 or 370. These drawings represent general plan views and profiles of the completed rehabilita on. As noted, site specific plans for proposed interior and exterior systems will be developed by the contractor. Architectural drawings and permits from previous renova on work can also be found in the specifica ons as A achment H, star ng on page 215 of

370.

20. Will there be any local permi ng requirements?

The Na onal Park Service, Point Reyes Na onal Seashore is the agency of jurisdic on. No local agency permits are required for work ac vi es on park lands.

21. Who is the JHA for fire life safety?

The Na onal Park Service is the jurisdic on having authority for fire life safety.

22. Who is the JHA for the sep c/environmental scope items?

The Na onal Park Service is the jurisdic on having authority for sep c/environmental items.

23. Is there any Mold and asbestos report and abatement included in this bid?

There are no mold or asbestos reports for the property. The main house was extensively renovated circa 1990, and the dance studio and garage were built subsequent to that renova on. Very li le of the original main house remains. Asbestos is considered unlikely to be present based upon the extent of renova on and me of construc on. As such, asbestos abatement is not included in the scope of work. Specifica ons sec on 02 42 00 CLEANING AND

REMEDIATION includes the cleaning and remedia on of mold. Mold is visible in some areas as you will note during the site visit.

24. Is it acceptable to have one person cer fied QC/Safety/Superintendent on site? Or do you need separate QC manager and safety manager on site?

One person may hold mul ple roles as long as they meet the qualifica ons for the roles and are able to perform the required du es of each.

25. Sec on 01 31 00 Project Management and Coordina on, page 1 Related Requirements, item 4 references “Sec on 01 91 14 Total Building Commissioning……..” that sec on is not included in the specifica on book. Please advise.

Total Building Commissioning is not included in the scope of work or specifica ons. Line item 4 in

Sec on 01 31 00 Project Management and Coordina on on page 1 was inadvertently le in the document but should have been deleted. Please ignore any references to Total Building

Commissioning or Sec on 01 91 14.

26. For the Dunn House project, will the bid results be published on the bid day (7/14) so bidders have an idea if they are low? If not the same day then when?

No, this isn’t sealed bid, it’s nego ated procurement. The proposals will be evaluated for best value and any award decision will be posted to sam.gov in addi onal to individual no fica on to unsuccessful offerors. The evalua on process takes about 2 weeks. Once the award decision is known, we send out required pre-award no ces so offerors will know who the apparent awardee is while the award is pending final clearance reviews, which can take about 1 month.

We an cipated awarding mid-late August.

27. I am seeking clarifica on on a sec on of the Solicita on. For Factor 2 California Contractor

License do both the Prime contractor and the subcontractor have to have the license or can it just be the subcontractor?

We understand there may be wide variety of team configurations that offerors may choose to employ. We require a California Contractor State License as applicable to the type of work being performed on this project. This is why the Solicitation instructs you to describe in detail in your proposal who will be performing what work with what license. While there may be acceptable scenarios where the proposed prime contractor does not have a license but the subcontractor does, the possession of a current and valid State License applicable to the work performed will be more favorably rated.

28. Is this a brand new contract OR was an incumbent performing these services?

This is a new requirement.

29. Specifica on lacks informa on to clearly specify ceiling le. Please clarify item number to quote, or confirm that we are using the cheapest op on that fits characteris cs in Spec.

46. What is the required review period for submi als and RFIs—10 working days or another dura on?

The specifica ons provide 30 days for an ini al review and five days for re-submi al reviews of ac on submi als. Ten days are provided for reviews of informa onal submi als. However, these are maximums and rarely would that much me be required for a review. The CO/COR will review each individual submi al and will respond accordingly based on the cri cal nature of each. Most submi als and requests will be responded to within five business days or less.

47. Is Microso Project an acceptable format for the construc on schedule, or is Primavera P6 required?

Microso Project is an acceptable construc on schedule format.

48. Are work hour excep ons available for cri cal path items or u lity shutdowns, and what is the process to request weekend/evening work?

Post-award, the successful contractor shall provide both a performance bond (Standard Form 25) and payment bond (Standard Form 25A) within 10 days of award, each at 100 percent of the original contract price. If any or all op ons are awarded at the me of award, that amount would be considered part of the original contract price.

The Government may require addi onal performance and payment bond protec on if the contract price is increased. The increase in protec on generally will equal 100 percent of the increase in contract price.
