A check of the Contractor's references indicates it has satisfactorily completed similar projects for other municipalities. Because of the unusual nature of this work and the advanced age of the marine structure, Staff recommends establishing a 15% contingency to cover the cost of unforseen work. This contract is comprised of two projects. (1) Rhine Wharf Repairs: This project includes removing and replacing boardwalk support beams and planks, inspecting sheet piles and tie rods, repairing concrete sheet piles and coping, applying preservative treatment to wood decking, and upgrading guardrails. The inspection of the tie rods involves removing a strip of concrete approximately 2' -6" wide with the subgrade along the boardwalk to expose the tie rods where they connect to the coping. Once the tie rods are exposed, City Staff will determine if any tie rods need to be replaced. For any tie rod replaced, the contractor will be paid per Additive Bid Item 1. The contractor will have 45 consecutive working days to complete the work for the wharf repairs. Additional time will be allowed for any tie rod replacements. (2) Rhine Channel Public Dock: This is a design -build project. The contractor will first prepare and submit to the City a design for the precast concrete platform with guard railings, floating dock with pre- stressed concrete piles, and handicap - accessible aluminum gangway. After City review, approval, permitting, and the Notice to Proceed issued, the contractor will have 120 consecutive working days to construct the public dock. Contractor may work both projects concurrently Environmental Review: The Rhine Wharf Repairs project is exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15301, Class 1 of the CEQA Guidelines.
