FOR PHASE 2 OF THE HUNTINGTON DRIVE CAPACITY IMPROVEMENTS PROJECT, AND AUTHORIZE THE FINAL PAYMENT TO BE MADE IN ACCORDANCE WITH THE CONTRACT DOCUMENTS Recommendation: Approve SUMMARY On December 16, 2014, the City Council awarded a contract to GMC Engineering, Inc. in the amount of $557,010 ($506,373 plus a 10% contingency) for Phase 2 of the Huntington Drive Capacity Improvements Project. There were three (3) change orders issued during the project, with the total not exceeding the 10% contingency. With the final adjustment for change orders and actual quantities, the contract increased by $41,865.39. The terms and conditions of this project have been complied with, and the required work has been performed to the City's satisfaction, for a final cost of $548,238.39. It is recommended that the City Council accept the project as complete, and authorize the final payment in accordance with the approved contract documents. BACKGROUND In 2012, the City undertook a project to complete traffic improvements along Huntington Drive at Santa Anita Avenue, Santa Clara Street, and Colorado Place. The project included additional left turn lanes on Santa Anita Avenue at Huntington Drive, an additional right turn lane on Huntington Drive eastbound at Santa Clara Street, and an additional through lane on Huntington Drive at Colorado Place. The project was funded in part by a grant from the Los Angeles County Metropolitan Transportation Authority ( "Metro ") and was completed in December 2012 at a cost substantially lower than the budget. Metro allowed a time extension on the grant for the City to complete additional Contract with GMC Engineering August 4, 2015 Page 2 of 3 work items that could not have been constructed earlier due to right -of -way constraints. The right -of -way was subsequently received as part of a new development project. A second project was assembled and referred to as "Phase 2" of the Huntington Drive Capacity Improvements Project. The Phase 2 project included the installation of a raised median in Huntington Drive from Santa Clara Street to Colorado Place, an additional lane in Huntington Drive west of San Rafael Road, traffic signal improvements, and sidewalk access ramp enhancements. The project was advertised for bids in September 2014, and bids were opened on October 7, 2014. The successful low bid was from GMC Engineering, Inc., in the amount of $506,373. The bid was presented to the City Council for award on October 21, 2014. At that meeting, two neighboring property owners expressed concerns about the project because they felt that the proposed raised median in Huntington Drive would create the need for U -turns at both adjacent intersections. The City Council continued the item to allow additional time to review the U -turn situation. On December 16, 2014, the bid was again presented to the City Council for award with an option to modify the median to allow U -turns at Colorado Street. The City Council awarded the contract to GMC Engineering Inc. without any additional modifications to the median. DISCUSSION The construction began in early January, 2015 and was not completed until early June, 2015. The project experienced delays due to the City's purchase of the 100 -to -1 Club property, and traffic signal equipment orders and deliveries. There were three (3) change orders on the project. The first change order was to remove the 100 -to -1 Club driveway access and construct new curb and sidewalk in its place. The second change order was to add pavement grinding around the new median, additional street light conduit, and concrete encasement of traffic signal conduit. The third change order was for additional signage, modifications to traffic signal equipment for the northbound to westbound left turns, and relocating traffic signal conduit for a new water vault installation. Final quantities of asphalt, sidewalk, and curb and gutter increased through the process of construction from the original plans in order to create smooth transitions and improve the finish of the project. The breakdown of the change order costs is as follows.. CHANGE ORDER AMOUNT 1 $9,670.00 2 $4,608.96 3 $3,032.99 Final Quantities $24,553.44 TOTAL $41,865.39 Contract with GMC Engineering August 4, 2015 Page 3 of 3 The contract increase of $41,865.39 brought the final construction total to $548,238.39, within the approved 10% contingency for the project. FISCAL IMPACT In the Capital Improvement Programs for Fiscal Year 2009 -10 through Fiscal Year 2011 -12, the City Council approved a total budget of $2,500,000. The initial construction project expended $1,400,000, leaving approximately $1,100,000 available for Phase 2. Therefore, sufficient funds remain to cover the total construction cost of $548,238.39 for the final phase of the project. RECOMMENDATION It is recommended that the City Council accept all work performed by GMC Engineering, Inc., for Phase 2 of the Huntington Drive Capacity Improvements Project as complete, and authorize the final payment to be made in accordance with the contract documents.
