About this opportunity
The contract opportunity involves the construction of the Lynnhaven River Basin Phase II Reef, which includes the transportation, sorting, and placement of fossil shell from Craney Island, and the installation of a base substrate layer and a top fossil oyster shell layer. The reef substrates will be placed by mechanical clamshell from a barge and recorded by GPS to ensure proper placement, with as-built surveys required between substrate layer placements. The construction period of performance is estimated to be approximately 720 days from the issuance of the Notice to Proceed (NTP), with the bid due date set for 26th October 2023.
List of Products and Services:
- Construction of the Lynnhaven River Basin Phase II Reef.
- Transportation of fossil shell from an existing pile on Craney Island.
- Sorting and cleaning of the fossil shell from debris and fine sediments.
- Placement of the base substrate layer (Size 2 crushed stone) and the top fossil oyster shell layer.
- Use of a mechanical clamshell from a barge for reef substrate placement.
- GPS recording of reef substrate placement.
- Conducting as-built surveys between substrate layer placements.

Bid Due Date is 26 OCT 2023 at 2:00 PM EDT. Amendments 0001 and 0002 should be acknowledged with all Bids.
The purpose of this acquisition is to construct the Lynnhaven River Basin Phase II Reef. The reef will be constructed with a targeted height of 12 inches off the river bottom, with the alternative base substrate layer (Size 2 crushed stone) being approximately 6 inches thick and the top fossil oyster shell layer being approximately 6 inches thick. For the fossil shell layer, the Project requires transporting the shell from an existing pile on Craney Island prior to placement within the project boundaries. The shell must also be sorted, clean from debris and fine sediments. All reef substrates will be placed by mechanical clamshell from a barge and recorded by GPS system to ensure proper placement. As-built surveys will be required between substrate layer placement to ensure targeted height is being reached. Reef substrate will be installed per the plan drawings and specifications on the project site in water depths ranging from approximately 7.0? MLLW to 8.3? MLLW. The construction period of performance will be approximately 720 days from issuance of the NTP.
