Questions and Answers:

QUESTION 1: Attachment #1 under Key Personnel, it states that a Project Manager, On-

Site Superintendent, On-Site Quality Control Manager, and an On-Site

Safety Manager are to be assigned to this project. An the last two positions

(quality control manager, and safety manager) be performed by 1 individual?

ANSWER 2: One person can perform the combined roles of the Quality Control

Manger and Safety Manager.

QUESTION 2: What is the Subcontracting percentage allowed for this project?

ANSWER: Solicitation Attachment no. 9, Limitations of Subcontracting (excel worksheet) is for contractor to include at the end of the contract.

Solicitation Attachment 1, Terms Clauses Provisions, Section I, Contract

Clause, incorporates by reference FAR clause 52.219-14, Limitations on

Subcontracting. The clause in full text states: The Contractor shall perform on the site, with its own organization, work equivalent to at least fifteen

(15) percent of the total amount of work to be performed under the contract. This percentage may be reduced by a supplemental agreement to this contract, if, during the performing the work, the Contractor requests a reduction and the Contracting Officer determines that the reduction would be the advantage of the Government.

QUESTION 3: Runtime / Duty Cycle Requirements. Please clarify the anticipated operational runtime and duty cycle requirements for the new generator system. Since this is an off-grid photovoltaic system with battery integration, please confirm expected annual operating hours and whether the generator is intended for continuous prime operation, peak shaving, battery charging support, emergency backup operation, or a combination thereof. This clarification is requested to confirm compliance with the specified generator rating and applicable air permitting requirements.

ANSWER: The generator for the rehabilitated off-grid PV-battery system is not intended for continuous prime operation. It will be used as an auxiliary source for battery-charging support, supplemental capacity during peak conditions (this is not expected with the expansion of the PV system capability), and emergency/resiliency backup. Annual operating hours are not prescriptively defined and will vary with solar production and load demands. The design intent is for the PV + battery system to serve as the primary power source, reducing dependency on the generator.
