BACKGROUND: RL Larson Excavating, Inc. was awarded a construction contract to complete the I-94 Lift Station (No. 1) and Sanitary Sewer Improvements on May 2, 2017. The contractor has completed the work in accordance with the contract, plans, and specifications; and with approval of this change order the contract amount will be adjusted to reflect the actual quantities installed as a part of the project. PROPOSAL DETAILS/ANALYSIS: RL Larson Excavating, Inc. has submitted a compensating change order to reconcile the estimated and actual quantities installed on the project. FISCAL IMPACT: $13,581.35 increase to the final construction contract amount. This compensating change order will increase the final construction contract amount to $902,903.57. The original construction contract amount at the time of award was $809,129.70. The increase is due to additional work items requested by the city including additional pavement and sanitary sewer at the lift station, as well as additional quantities associated with rebuilding the shoulder and turn lane on Hudson Boulevard. RECOMMENDATION: Staff is recommending that the City Council approve, as part of the Consent Agenda, Compensating Change Order No. 4 for the I-94 Lift Station (No. 1) and Sanitary Sewer Improvements. If removed from the consent agenda, the recommended motion for the action is as follows: “Move to approve Compensating Change Order No. 4 for the I-94 Lift Station (No. 1) and Sanitary Sewer Improvements, thereby increasing the contract amount by $13,581.35”.
