Answer: Means and methods are not dictated, contractor shall take reasonable precautions to not damage utilities in utility rich areas or in areas where unprotected utilities are present.

4. Question: Are the trees staying near the areas where equipment is located near NCO Drive?

Answer: Yes.

5. Question: What is the water line depth on base?

Answer: Varies. Assume a minimum of 5-6ft.

6. Question: Is there water connection on site for providing water for fire suppression?

Answer: BESS system shall meet the requirements of UL9540A and NFPA 855. BESS battery section shall be provided with self-contained, internal fire suppression system with water supply located in a tank within the BESS enclosure. Remaining sections of BESS for inverter and other components outside the battery area to be chemical type system (i.e. Novec). BESS shall have the required fire/smoke detection, gas detection and ventilation as required by NFPA 855.

7. Question: Does Option #6 Stone Drainage only include area under the Base Bid?

Answer: Price for Option #6 shall include the entire solar panel area encompassed by both Base Bid and Option #3.

8. Question: The written specification says:

The BESS shall be rated at 125 kVA at 0.95 pf and deliver 125 kWh at End of Life year 20 at point of interconnection.

1. The BESS shall be rated at 250 kVA at 0.95 pf and deliver 250 kWh at End of Life year 20 at point of interconnection.

2. The BESS shall be rated at 250 kVA at 0.95 pf and deliver 500 kWh at End of Life year 20 at point of interconnection.

The drawings call for a BESS that is:

125kW/125kWH 250kW/250kWh or 250kw/500kWh

Please confirm that delivering 125, 250 and 500kWh at 20-year end of life is correct as this increases the size of the ESS.

Answer: The BESS rating shall be based on the "End of Life year 20 at point of interconnection" per the specifications.
