Solicita on 140P8425R0002, A achment 9, Q-A & Amendment 3

The Dunn property water is supplied via a shallow well. The shallow well is located approximately 1,000-feet southeast of the Dunn Main House. The water from the shallow well is considered surface water. Water from the well is pumped into four (4) 3,200-gallon storage tanks located approximately 200-feet east of the main house.

The capacity of the system is currently unknown but assumed to be sufficient to provide up to

3,000 gallons per day to the Dunn property. Future water supply improvements will be made separate from this project to the source to ensure consistent supply of 4,500 gallons per day to the storage tanks.

57. In order to upgrade electrical to code, and to provide all requested addi ves, we will need to significantly increase the service size. What is the outcome of your conversa ons with PG&E regarding this?

For any service upgrade or new service meters, PG&E will require a project applica on from NPS containing project details, including proposed load sheets and line drawings. This informa on will be reviewed and approved by PG&E. Construc on of upgrades to the service and/or new service meter connec ons by PG&E will be coordinated by NPS and PG&E as needed based on informa on to be provided by the contractor. PG&E es mates 182 calendar days from the me of applica on to service energiza on.

All new siding is proposed as Hardie Shingle Straight Edge Panel (cedar shake style) fiber cement shingle siding or approved equivalent. The apparent lap siding shown on A01 and A02 are general siding visualiza ons used to indicate siding loca ons only. Cedar shake style is not a salient characteris c of the requirement. Other materials and visual styles of siding that are Class

A fire rated would be considered (e.g. steel, composite, engineered wood, plank, lap).

67. Please confirm if a wet pipe system is acceptable throughout, including in uncondi oned areas, or if a dry system is required in those loca ons due to climate concerns.

a. Will construc on drawings for the new foo ng and stem wall be provided by the NPS?

b. Or should the contractor design and submit drawings for approval by the NPS?

The intent for the Unit 3, South bedroom is to maintain the exis ng slabs and load bearing walls.

New stairs would be constructed to connect the south bedroom slab to the upper slab.

New interior walls and stairs will not require new construc on drawings from NPS or the Contractor.

70. Do you have a planholders list/sign in sheet available?

See the solicita on amendment a achments found with the solicita on on sam.gov for a list of site visit a endees. You may also visit www.sam.gov and search for the opportunity using keyword 140P8425R0002; there you should be able to see/add yourself to the Interested

The current supply would be the elevated storage tanks located adjacent to the main house. A future fire pump would be expected to be designed in accordance with NFPA 20. Required flow rates would be expected to be supplied at 40 psi or greater. The pump must deliver water at the correct pressure to ensure the fire suppression system func ons properly, typically at 65% of the pressure at 150% of the rated flow.

73. Can we get the bid date extended a week since we are s ll wai ng on addi onal informa on for a number of the bid items?
