SUBMITTED BY: Richard Dublinski, Director
BACKGROUND:
In June 2019, City Council awarded Contract 19-060 to Hoerr Construction Inc. to clean, televise and install cured-in-place-pipelining (CIPP) in storm sewer segments. The term of the contract is from date of award to December 5, 2019, with two, one-year options to extend. The purpose of this contract is to rehabilitate storm sewer pipe ranging from 8 inches to 30 inches in diameter, which will improve the conductive capacity and extend the useful lifespan of the existing storm sewer system.
In 2019, work includes approximately 14,000 feet of pipe in grids 113, 114, 128, and 129 (West Highlands) as well as single run repair sections in other grids. The contract also includes two standalone projects to line the culverts on Olesen Drive and Hobson Mill Drive.
DISCUSSION:
The amount of this change order exceeds the original contract amount by $13,642 and increases the original contract expiration date by zero days.
The Department of Public Works (DPW) developed the bid documents for Contract 19-060 using GIS data to identify the size and length of the pipes, which results in estimated quantities. When the contractor begins cleaning and televising the pipes, the size and length of each pipe is verified. This change order is requested to incorporate size changes that were identified during the contractor’s field inspections. A summary of the requested quantity changes is attached.
This contract was approved with contingency in the amount of 3% ($22,191.30) of the original contract value. Staff requests the use of contingency for the change order. A summary of the award and contingency information is provided in the tables below:
