Body
Issue/Request:
An Ordinance approving Change Order #2 to the contract with Leavenworth Excavating and Equipment Company, Inc. for the Langsford Rd culvert repair project, for an increase of $20,000.00 for a revised contract price of $683,017.05 and an increase of 5 calendar days to reach substantial and final completion.
Key Issues:
• An existing sanitary sewer service lateral was found to be in direct conflict with the box culvert installation.
• In order to route the sanitary sewer service around the new structure, 170 feet of four inch sewer line and one sewer manhole must be installed.
• An additional 5 calendar days will be added to the contract to complete this work.
Proposed City Council Motion:
FIRST MOTION: I move for a second reading of an Ordinance approving Change Order #2 to the contract with Leavenworth Excavating and Equipment Company, Inc. for the Langsford Rd culvert repair project, for an increase of $20,000.00 for a revised contract price of $683,017.05 and an increase of 5 calendar days to reach substantial and final completion.
SECOND MOTION: I move for adoption of an Ordinance approving Change Order #2 to the contract with Leavenworth Excavating and Equipment Company, Inc. for the Langsford Rd culvert repair project, for an increase of $20,000.00 for a revised contract price of $683,017.05 and an increase of 5 calendar days to reach substantial and final completion.
Background:
The scope of this project included the construction of a concrete flowline inside of two existing 128” x 83” corrugated metal pipes. In areas where the pipe flowline was significantly corroded, additional work was included to remove the deteriorated sections of pipe to stabilize the material under the pipe. While working on the north end of the project, a large section of pipe was found to be partially collapsed. As a result, 85 feet of twin 128” x 83” pipe needs be removed and replaced. This additional work was included in Change Order #1. While excavating for the new structure, a sanitary sewer lateral was discovered laying directly on top of the original culvert pipes. As a result, 170 feet of four inch sewer lateral and one manhole will be required to route the sewer lateral around the new structure.
An additional five days will be added to the contract to account for this additional work.
