Drainage Repairs 1230 Area SWP13

Amendment / Modification

This amendment provides answers to vendor requests for information regarding the solicitation N40085-26-R-9020 for Drainage Repairs 1230 Area SWP13.

Key clarifications include:

• Pipe Sizing: For a 27" pipe noted on drawing C102, the existing pipe is 27" CMP. The contractor should provide equivalent RCP to ensure proper separation of utilities. A suggestion for a 30" RCP was made, but the government clarified to match the existing size with equivalent material.
• Streetlight Removal/Reset: The base will not support temporary streetlight removal. The lights are fed from the back of Building 1231. The lighting circuit will be down for approximately one month.
• Forebay Size: The hatch mark for note 8 on drawing C102 is inaccurate regarding the forebay size. The forebay is approximately 90 feet long from the retention pond edge to the pipe outlet, with an existing slope of 2:1. The intent is to refresh the entire forebay.

This amendment addresses specific questions related to drawings and site conditions.

The time and date for receipt of proposals remain unchanged. Bidders are reminded to acknowledge this amendment when submitting their proposal, as failure to do so may result in rejection.
