140P2022R0045 Questions and Answers – Amendment #0004 08/05/2022

The following is a consolidated list of current vendor questions. Responses in red shall address questions not previously responded or to provide updates to questions in which responses had been previously provided. Please note that responses in blue (other than email or web page links) are pending responses, which will be provided in a future amendment.

1. Will all six base bid prices be awarded as one package?

Response: Yes, base bid items shall be awarded as one package. Any or all options may be awarded in the original award.

2. Section H, in the solicitation mentions the Government may pick from the separate options and contractor will need to hold the price for 180 days after award. Most material suppliers are only holding pricing for 15 days or less at this time. We assume this would not apply if all six base bids are awarded as one?

Response: Bid proposals will need to hold prices as indicated in the solicitation, price proposals will reflect the risk.

3. Have any Geotechnical investigations been performed onsite? Would it be possible to have the reports issued?

Response: Final Geotechnical Report attached. See Attachment 01a-Q03-Geotech Report to Amendment 0003.

4. We recommend an allowance be carried in the bid for utility connections at the street. Often times the utilities companies will not give contractors a solid estimated cost.

Response: We did not include costs for utility connections, because water/sewer/telcom are all connecting to existing NPS systems on the site. A new electrical service connection is being made, with a new branch from the main power line along Rte 233 to our pole, but the connection cost is included in their service contract. This was confirmed again this week with the Versant representative.

5. Please provide Utility Company point of contact who is established for the project, so we can coordinate their scope with electrical subcontractor.

Response: The Versant Power representative is Robert Peaseley (robert.peaseley@versantpower.com; office: 207-973-2518; cell: 207-299-5834). This information is provided on drawing E12.
