Change Order No. 1 with Garney Companies for the 54" Southeast Interceptor Sewer Emergency Repair project (COF Contract No. 2017-0131) for an Increase to the Contract in an Amount Not-To-Exceed $1,174,390.00
Purpose
The purpose of this memo is to provide information to the Franklin Board of Mayor and Aldermen (BOMA) concerning the Change Order No. 1 with Garney Companies for the 54" Southeast Interceptor Sewer Emergency Repair project (COF Contract No. 2017-0131) for an Increase to the Contract in an Amount Not-To-Exceed $1,174,390.00.
Background
The original project with Garney Companies Inc. to replace sections of the 54” sanitary sewer line that had collapsed was approved June 21, 2017. After construction started, a large rain event caused the Harpeth River to overflow its banks and flood the open construction trench where the manhole cone sections upstream had been removed to allow bypass pumping of the sanitary sewer around the construction site. Large amounts of debris were deposited into the 54” sanitary sewer pipe between the two sections of line of the original construction project. The City compared the costs of cleaning the pipe versus replacing the pipe and decided to replace the 414 feet of pipe between the two manholes involved in the bypass pumping.
Financial Impact
Increase to contract in the amount of $1,174,390.00
Recommendation
Staff recommends approval of Change Order No. 1 with Garney Companies for the 54" Southeast Interceptor Sewer Emergency Repair project (COF Contract No. 2017-0131) for an Increase to the Contract in an Amount Not-To-Exceed $1,174,390.00.
