The project entails the removal of existing concrete structures, installation of new steel sheet pile bulkheads, and various mechanical, plumbing, and electrical upgrades across four marina basins, while adhering to strict environmental protections due to the presence of federally protected species. This construction initiative, valued between $25 million and $100 million, is set to be awarded as a Firm-Fixed-Price contract, with a performance period of 1,350 calendar days from the Notice to Proceed. Interested vendors must register on the SAM.gov website and submit proposals electronically via the Procurement Integrated Enterprise Environment (PIEE) by the specified deadlines, with inquiries directed to Ireishal Adams at Ireishal.C.Adams@usace.army.mil or William Wallace at William.J.Wallace@usace.army.mil.
