SR-07-08-2014-3ACity Council Meeting: July 8, 2014 Agenda Item: � L To: Mayor and City Council From: Martin Pastucha, Director of Public Works Subject: Exposition Light Rail Intersection Pavement Betterments on Colorado Avenue Recommended Action Staff recommends that the City Council: 1. Authorize the City Manager to negotiate and execute an agreement with the Exposition Metro Line Construction Authority (Authority) in an amount not to exceed $500,000 (including a 5% contingency) to upgrade the roadway pavement to concrete paving at five intersections on Colorado Avenue. 2. Authorize the Director of Public Works to issue any necessary change orders to complete additional work within budget authority. Executive Summary On September 13, 2011, Council authorized the Master Cooperative Agreement (MCA) with the Exposition Metro Line Construction Authority. Per Section 9.3 of the MCA, City -owned facilities, including roads and intersections, may be replaced in kind at the City's request. City staff identified concrete pavement as necessary betterments, as defined in the MCA, to five existing intersections along Colorado Avenue which are currently asphalt concrete pavement. These betterments are recommended to be installed during the construction of the Exposition Light Rail (EXPO) project to minimize future traffic and operational interruptions to the rail line. In addition, implementation of these betterments will result in cost savings to the City versus performing the improvements after the EXPO Project is completed. Background The EXPO Line will connect Downtown Los. Angeles to Downtown Santa Monica. There are three stations in Santa Monica officially named 26th Street/Bergamot, Colorado /17th Street/SMC, and Downtown Santa Monica. The Authority is designing and building the EXPO Line. Once completed, it will be turned over to the Los Angeles County Metropolitan Transportation Authority (Metro) for operation. Phase 1 of the line 1 to Culver City opened in April 2012 with Phase 2 to extend the line to Santa Monica and 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 Memorial Park /17th Street Station. On May 24, 2011, Council authorized a funding agreement between the City, the Authority, and Metro to pay for baseline elements of the light rail and stations. 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 negotiation 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, On June 25, 2013, Council authorized an agreement with the Authority for Storm Drain Repairs and Replacement on Colorado Avenue. On August 13, 2013, Council authorized funding for the design and construction of upgraded street lights on the south side of Colorado between 5th Street and 16th Street. 2 Discussion The Authority and its design - builder, Skanska -Rados Joint Venture (SRJV), have completed final design on all necessary City -owned infrastructure along Colorado Avenue. The final roadway design along Colorado Avenue between 5th Street and 17th Street was replaced with pavement materials in kind. There are five intersections on Colorado Avenue currently constructed in asphalt pavement. These intersections are located at 5th Street, 7th Street, 11th Street, 14th Street, and 17th Street. There are two other intersections currently constructed in concrete pavement, 6th Street and Lincoln Boulevard, which will be reconstructed with concrete pavement as part of the baseline project, with the reconstruction of the Lincoln Boulevard intersection recently completed. Upgrades The Authority is installing tracks in the middle of Colorado Avenue. The tracks are embedded in concrete. The intersections on Colorado Avenue are proposed to be partially constructed in concrete, within the 26 -foot track guideway section. The remaining section of the intersection is to be constructed in asphalt pavement. City staff determined it would be beneficial and cost efficient to upgrade and improve the baseline design by constructing the five intersections entirely in concrete. Concrete intersections are more sustainable and last longer, requiring less maintenance versus asphalt concrete intersections. Completing this work now would prevent future street closures for repairs to asphalt, thereby impacting traffic for businesses, residents, tourists, fire, and police. The future street configuration would be condensed and any future construction within 10 feet of the dedicated railway would have to be performed during Metro's limited non - operating hours (2 -5 AM), thus costing more and having a longer construction time in the future. Negotiations The Authority obtained cost proposals from SRJV for the City- requested betterments. Authority and City staff reviewed the cost and determined that it is competitive and 3 comparable to other similar work conducted at the Downtown Santa Monica Station, Colorado /17th Street /SMC and 26th Street /Bergamot Stations. The work conducted in these locations included concrete pavement work similar in scope and unit price to the requested betterment. A credit in the amount of $45,000 would be applied toward the proposed betterment, which is equal to the cost of paving the remainder of the intersection in asphalt pavement. The Authority has agreed not to charge an overhead fee on any betterment. In addition, a City controlled contingency of $23,111 would be budgeted by the City. Only changes authorized by the Director of Public Works would be approved for payment to the Authority. Financial Impacts & Budget Actions The agreement to be awarded to the Authority is for an amount not to exceed $500,000 (including a 5% contingency). The $500,000 amount includes the $45,000 credit to be applied toward the proposed betterment and the $23,111 City - controlled contingency. Funds are available in the proposed FY 2014 -15 Capital Improvement Program budget in account 0017061.589000.
