About this file
This document is an addendum to Request for Proposal (RFP) #2314 issued by the Darien Downtown Development Authority for dock improvements on the Darien River in Darien, Georgia, located in McIntosh County. The addendum provides updates to the proposal due date, material specifications for the fixed dock, floating docks, and gangways, as well as responses to questions received during the pre-proposal meeting. The fixed dock is to have an aluminum frame, Trex or similar composite decking, and aluminum or composite railings. The floating docks will also have an aluminum frame and Trex or similar composite decking. The gangways are to be 30 feet in length with aluminum construction and railings. The new proposal due date is April 19, 2024, at 10:30 AM.
The addendum clarifies that soil boring and wind test results are the responsibility of the contractor, and that neither of the 30-foot gangways are required to be ADA compliant. The addendum also provides guidance on piling placement and spacing, and notes that 3D drawings are intended as visual aids and not construction specifications. The RFP is a design-build project, and the contractor is responsible for providing the structural specifications.
