The Town of Fairfield (Town) on behalf of its Engineering Department (ENG) is seeking competitive bids from qualified Contractors to provide all labor, material, equipment, and all else necessary for the Verna Hill Road Culvert replacement as specified.

PROJECT OVERVIEW

This project is for the replacement of pipe/culvert under Verna Hill Road located near the intersection of Verna Hill Road and Hillside Road in Fairfield, CT. This culvert experienced damage during Storm Ida and is beyond repair. Replacement is necessary and is approved by USACE and FEMA and the Town of Fairfield Inland Wetland Commission. The damaged pipe is approximately 36 inch x 22 inch ACCMP sleeved within a collapsing 5 ft x 3 ft stone culvert used as a bypass pipe.

There is a “sister” 4.5 ft by 6ft high stone culvert that carries Browns Brook that was not damaged by the storm located approximately 80 ft west of the damaged pipe. The sister stone culvert will remain as is and is not in the project replacement contract.

PROJECT SCHEDULE

The awarded Contractor shall have site access upon contract execution. The Town is anticipating all work to be substantially completed by October 30th, 2025.

SITE VISIT

A site meeting will commence at Verna Hill Road and Hillside Road intersection, Fairfield, CT 06824 at 10:00am Thursday, 25th September 2025 for all prospective bidders who are interested in bidding this project.
