Lake Fairfield Boardwalk and Pedestrian Bridge REHAB Project Project Location

The project site is located on Lake Fairfield Drive in Greenville, South Carolina. The pedestrian bridge and boardwalk connects the end of Fairfield Drive with the cul-de-sac on Hermitage Road. The existing pedestrian bridge and boardwalk were completed in 2007. For the proposed work, the contractor shall take all the necessary measures to ensure the safety of the public and prevent damage to County roads/infrastructure, utilities, and private property.

Project Scope

The main purpose of the rehab project is to replace the boardwalk beams, joists, decking, handrail posts and rails. The existing 8"x8" boardwalk supports and cross bracing will remain. Originally, the deck for the 60' prefabricated steel bridge was to be rehabilitated but the revised project scope now includes replacing the bridge deck with 2x6 PT SYP covered with 5/4x6 hardwood, secured with self-tapping Tek screws. The contractor shall be responsible for demolition and removal of the boardwalk superstructure as shown on the project plans. The county has already removed screws for the bridge deck, so the contractor may easily remove/dispose of the 3x8 pine boards.

Alternate Scope

The alternate scope consists of replacing boardwalks and bridge deck with P.T. SYP lumber (no hardwood).

Utility Protection

This project does not contain excavation or land disturbance activities; however, the contractor shall be responsible for any damage occurring to utility lines on the project site and shall be responsible for the required repairs at contractor’s expense.
