It is recommended the City Council accept all work performed by MNR Construction, Inc. as complete and authorize the final payment to be made in accordance with the contract documents, subject to retention of $21,038.50. DISCUSSION The 2006 Sewer Master Plan evaluated the adequacy of the City's wastewater collection system and identified sections of the system which were considered deficient. Baldwin Avenue (between Huntington Drive and Fairview Avenue) and Old Ranch Road (near the intersection of Victoria Drive) are two sections which were identified as areas in the City's sewer system that were at capacity and thus, needed to be increased to accommodate the sewage and eliminate the possibility of a sewer spill. Mayor and City Council November 6, 2012 Page 2 of 3 During the excavation phase of work, sandy soils and sloughing of the trench sidewalls made it difficult for the contractor to maintain a uniform trench. Project Management staff worked with the contractor to determine what was reasonable to consider as the contractor's responsibility and what should be considered extra work due to unexpected field conditions. The change order described below represents the negotiated agreement for extra work performed by the contractor: CCO # Description Amount 1. Compensation for additional backfill and asphalt paving $ 7,150.00 due to unanticipated unstable soil conditions The terms and conditions of this project have been complied with and the work has been performed satisfactorily according to the contract documents for a total project cost of $420,770. This amount reflects the original contract amount of $413,620 plus one contract change order totaling $7,150 or 1.7% above the original contract amount. Therefore, it is recommended that the City Council accept all work performed by MNR Construction, Inc. as complete and authorize the final payment to be made in accordance with the contract documents, subject to retention of $21,038.50.
