Background: In March of 2009, the California Department of Transportation (Caltrans) and the City of San Bernardino entered into a utility agreement as part of the realignment and widening of the 1-210 Freeway. The agreement, which required Caltrans to reimburse the City for all engineering, inspection and construction costs associated with the relocation of conflicting sewer facilities within Segment No. 11, was approved by the Mayor and Common Council on March 16, 2009. The sewer relocation project involved the Segment No. 11 1-21011-215 Interchange Improvements, which included sewer relocations at 27h Street and a portion of Little Mountain Drive. Under the utility relocation agreement, Caltrans agreed to reimburse the City for all costs associated with the relocation of conflicting sewers related to the Segment 11 I-210/1-215 Interchange Freeway Improvements up to and amount of$412,500. On July 6, 2009, the Mayor and Common Council approved the award of a contract to El-Co Contractors, Inc. for Sanitary Sewer Improvement Relocations for the I-210 Freeway Widening, Segment 11 (SW09-03), per Project Plan No. 12517. Construction Change Order No. One: During construction, the contractor discovered that the existing sewer line location differed from the one shown on the approved plans by Caltrans, causing delays and re-design work. In addition, relocations of an undocumented conflicting utility, and siphoning of an existing water line were included in the project as part of the changes and approved by Caltrans. This additional work was not included in the contractor's original bid. The descriptions and justification of these items are detailed in the attached copy of Contract Change Order No. One. Financial Impact: The revised estimated project costs are as follows: TOTAL Original Contract Amount $ 195,033.00 Adjustment due to Reduced/Deleted Items $28,918.00 Contract Change Order No. One $ 105 080.89 Total Construction Contract Amount $ 271,195.89 2 CITY OF SAN BERNARDINO-REQUEST FOR COUNCIL ACTION STAFF REPORT—Continued This change order represents a net increase of 53.9% of the original contract amount. There are sufficient funds in the project account to cover this change order. The change order exceeds the 10% contingency, but the actual inspection costs were less than estimated in the original design phase, so no additional funds are needed for this project. In addition, the City will be reimbursed 100% of the final construction cost including change orders from Caltrans. The project was recently completed. Account Budgeted Amount: $ 3,012,100. Balance as of: 03/05/2010. Balance after approval of this item: $2.907.019. Please note this balance does not indicate available funding. It does not include non-encumbered reoccurring expenses or expenses incurred but not yet processed.

This additional work was not included in the original contract bid item. Extra Work on 2 Sewer Manholes 1-5 During construction it was determined that the contractor was required to modify two existing manholes of the sewer line.

Additional Work Done to Siphon Water Main on 27' Street During construction, it was discovered that there was a conflict between the proposed sewer main and existing water main along 27' Street,which was not shown correctly on 1-7 the approved plans; therefore, it was necessary for the contractor to siphon the water main in order for the contractor to construct the proposed sewer main per the approved plans. This additional work was not originally anticipated and was not included in the original contract bid item. Additions Done on Time and Material and Equipment Basis on Asphalt Concrete Pavine 1-8 During construction, it was discovered that the contractor was required to perform additional asphalt concrete paving beyond and above the original contract bid item (up to 125%); therefore, it was necessary for the contractor to complete the said paving work on a time and material basis. 2 CHANGE ORDER NO.ONE-EL-CO CONTRACTOR,INC.
