SR-06-25-2013-3X - 405-006 / 505-004City Council Meeting: June 25, 2013 Agenda Item: "?� To: Mayor and City Council From: Martin Pastucha, Director of Public Works Subject: Exposition Light Rail Storm Drain Repairs and Replacement on Colorado Avenue Recommended Action Staff recommends that the City Council: 1. Authorize the City Manager to negotiate and execute an agreement, in an amount not to exceed $274,566 (includes a 10% contingency) with the Exposition Metro Line Construction Authority (Authority) to repair and replace six storm drain laterals on Colorado Avenue between 6th Street and 11th Street. 2. Authorize budget changes as outlined in the Financial Impact and Budget Actions section of this report. 3. Authorize the Director of Public Works to issue any necessary change orders to complete additional work within budget authority. Executive Summary The Exposition Light Rail Phase 2 Project (Expo Line) is currently under construction along Colorado Avenue. During the pre- construction survey of storm drains, the Expo Line design - builder, Skanska -Rados Joint Venture (SRJV), performed video documentation of all storm drains that are within the project limits. The video inspection revealed six deteriorated City storm drain pipes in need of replacement. The pipes were found having multiple cracks, holes, and collapses. Staff recommends authorizing an agreement with the Authority to perform the storm drain repairs and replacement on Colorado Avenue in an amount not to exceed $274,566. Background The Expo Line will connect Downtown Los Angeles to Downtown Santa Monica. The three stations in Santa Monica will be at the 26th Street/Bergamot Station, Colorado /17th Street/SMC Station, and the Downtown Santa Monica Station. The Authority is designing and building the Expo Line. Once complete, the Expo Line will be turned over to the Los Angeles County Metropolitan Transportation Authority (Metro) for operation. 1 Phase 1 of the line to Culver City opened April 2012, just as construction began on Phase 2 to extend the line to Santa Monica. Phase 2 of the Expo Line is scheduled to open in early 2016. On July 13, 2010, Council adopted a range of betterments to incorporate into the City's three Expo Line stations that included separate station platforms for east and west bound trains at the 26th Street/Bergamot Station and a second entrance at the Colorado /17th Street/SMC Station. On May 24, 2011, Council authorized a funding agreement between the City, Authority, and Metro to pay for baseline elements of the light rail and stations as the required 3% local match contribution for completion of the Expo Line in Santa Monica. On June 28, 2011, Council approved preliminary engineering services at Colorado /17th Street/SMC and 26th Street/Bergamot Stations. On September 13, 2011, Council authorized negotiations with the Authority for the betterments at these stations. On December 13, 2011, Council authorized an agreement with the Authority to perform final engineering and construction of betterments for the two stations. On January 24, 2012, Council authorized an agreement with the Authority for the required 3% local match and an agreement for engineering and construction of betterments at the Downtown Santa Monica Station. On September 11, 2012, Council authorized an agreement with the Authority for the final engineering services and construction of the betterments to the City water main on Colorado Avenue. Discussion The Authority and its design builder, SRJV, have completed final design for the necessary City facility relocations on Colorado Avenue. A portion of the City's storm drain system was identified for relocation since it was in conflict with the proposed Expo Line on Colorado Avenue. In addition, a number of storm drain pipes were to be 2 protected in place and did not conflict with the Expo Line. During the field verification of existing utilities SRJV performed video documentation of the storm drain lines within the project limits. Through video inspection, six storm drain pipes located on Colorado Avenue at 6th Street, 72h Street, 91h Street, 10th Street (two pipes), and 11th Street were found to have holes, cracks, and collapses. In addition to the video documentation, a written report was provided describing all found defects. Based on the findings and engineering evaluations, SRJV and Authority recommended replacement of the six pipes. Staff reviewed the videos accompanied by the inspection report and concur with the Authority's findings that the pipes need replacement or repair. Staff determined that it would be beneficial and cost effective to replace the pipes versus performing spot repairs and lining the pipes. On September 13, 2011, City Council authorized the City Manager to negotiate with the Authority and execute the Master Cooperative Agreement (MCA). The MCA states that the City is responsible for cost associated with replacement of the storm drain pipes with an expired service life or in need of repairs. City staff identified the necessary storm drain replacement scope, or betterments as defined in the MCA. These betterments are recommended for implementation during the construction of the Exposition Light Rail (EXPO) project to minimize future traffic and train operational interruptions. The repairs would not be feasible following completion of the EXPO line, since the storm drain lines will be located under the railway. In order to complete engineering design, replacement and repairs to the six storm drain pipes without impacts to the Expo Line construction schedule on Colorado Avenue, staff recommends an agreement in the amount of $274,566 with the Authority. The Authority obtained cost proposals from SRJV for the City- requested betterments or repairs. Authority and City staff reviewed the cost and determined that it is competitive and comparable to other similar work. The Authority has agreed not to charge an overhead fee on any of the storm drain repairs. In addition, a City controlled contingency of $23,500 would be budgeted by the City. Only changes authorized by the City's Director of Public Works would be approved for payment to the Authority. 3 Financial Impacts & Budget Actions The modification to be awarded to the Authority is for an amount not to exceed $274,566. The modification will be funded by a loan from the Wastewater Fund to the Stormwater Fund in the amount of $274,566. This loan will be repaid over five years at 1.5 percent fixed interest using future Stormwater funds. Budget authority for repayment of the Wastewater Fund loan for subsequent years will be requested in each budget cycle for Council approval. Completing these processes requires a budget appropriation of $274,566 to account 34274.569370 and the following transactions to recognize the loan: Debit 34.101101 Operating cash Credit 34.223082 Advance from fund 31 Debit 31.1130099 Advance to fund 34 Credit 31.101101 Operating cash Prepared by: Alex Nazarchuk, P.E., Civil Engineer Approved: Martin Pastucha Director of Public Works 10 Forwarded to Council: Rod Gould City Manager Reference: Contract No. 9760 (CCS)
