Conduct structural repair of storm-damaged catwalk pilings by Installing ten marine grade treated pilings alongside the damaged pilings and connecting them using SAE 316 stainless steel grade hardware and marine grade treated header boards.

Services Requested Contractor shall provide permanent installation of a total of ten new pilings alongside and connected to damaged pilings (as a “sistered” arrangement) on two catwalks in the following manner:

• Ten pilings to be replaced will be marked by station management.

• Photo provided for conceptual purposes only. Bidders should not rely on the photos for locations or measurements. These metrics should be measured, recorded, and calculated by the bidder.

• Bidder to determine piling length, based on a minimum of 10-ft ground penetration.

Distances from ground to the tops of the pilings range from approximately 14 to 16 feet.

• All existing pilings are to be left in place.

• Provide and install (drive) ten 12-inch butt 2.5 CCA (Chromated Copper Arsenate) marine grade treated pilings such that they are driven alongside the existing, damaged pilings. Note that if any part of the dock (framing, railings, decking, etc.) must be removed to drive pilings, the contractor is responsible for the removal and replacement of those materials.

The contractor will be responsible for any damage to existing materials that are to remain in place, as well as materials to be removed and reinstalled or replaced. Any material to be reinstalled must be reviewed and approved by station management before reinstallation.

• Connect the new pilings with the existing (as sister pilings) using SAE 316 stainless steel grade hardware and sixteen new 3” x 8” 0.60 CCA headers to span across the new pilings with 5/8” all-thread rods. All stainless hardware, including threaded rods, nuts, and washers, must be SAE 316 stainless steel grade hardware or higher for prolonged contact with marine salt water.

• Each set of eight sets of pilings will require a minimum of two header boards, two threaded rods, four flat washers, four lock washers, and four nuts (material specifications called out above).

• All work must be completed following all applicable local, state, and federal code requirements.

• Haul off/dispose of any trash resulting from this work.
