Home My WebLink About09-17-2019 Item 08 - Marsh St Bridge replacement - spec no 90480 Department Name: Public Works Cost Center: 5001 For Agenda of: September 17, 2019 Placement: Consent Estimated Time: N/A FROM: Shelly Stanwyck, Assistant City Manager, Community Services Prepared By: Michael J. McGuire, Senior Civil Engineer SUBJECT: MARSH STREET BRIDGE REPLACEMENT, SPECIFICATION NO. 90480 RECOMMENDATION 1. Approve construction documents for “Marsh Street Bridge Replacement, Specification No. 90480”; and 2. Authorize staff to advertise for bids; and 3. Authorize the City Manager to award a construction contract to the lowest responsible bidder following a selection process conforming to the Caltrans Local Assistance Procedures Manual. DISCUSSION Background The Marsh Street Bridge, located near the intersection of Marsh and Santa Rosa Streets, was approved by the City Council in January 2013 for removal and replacement (Attachment 1). This followed a determination by the California Department of Transportation (Caltrans) that the bridge, built in 1909, is structurally deficient. Upon this determination, the City contracted with Dokken Engineering to conduct a bridge assessment. This assessment concluded that a complete replacement of the existing bridge was the most prudent and cost-effective alternative given the age of the structure. City of San Luis Obispo engineering staff have been working with Dokken Engineering since 2010 to complete design of the bridge, as well as final environmental permitting and agreements for temporary and permanent construction easements from adjacent property owners. This work has resulted in the completion of the bridge plans and specifications for proceeding into the construction phase (Attachment 2). In addition to replacement of the bridge deck and railing, the project includes installation of new lighting for enhanced pedestrian safety. The lighting and railing will retain the historic aesthetic of the bridge. To accomplish the construction work, Marsh Street will be closed from the bridge to the Santa Rosa Street intersection with traffic diverted around the construction site. Packet Pg. 75 Item 8 The City is the local agency for the project, with the California Department of Transportation serving in an oversight role as the stewards of the State Highway System. Current status is: 1. June 2018, the City made offers to acquire right-of-way and temporary construction easements needed for the project. 2. November 2018, all necessary property acquisitions had been secured but the delays in construction start resulted in a need to extend ROW agreements for an additional 14 months. 3. The City submitted 100% plans for Caltrans review in January 2019. 4. Final approval of the Federal authorization form E-76 for construction from Caltrans was granted on April 18, 2019. Project Construction Currently, the City is in the process of issuing a Request for Proposals (RFP) for Construction Management (CM) services with the expectation of having a CM consultant contracted in November 2019. By December, it is anticipated that a construction contract will be awarded following a rigorous selection process mandated by the Caltrans Local Assistance Procedures Manual. Also, in December, there will be required environmental mitigation in the form of tree removals taking place prior to the riparian nesting season. Bridge construction is tentatively scheduled to start in Spring 2020 with construction concluding by December 2020. Part of the decisions related to timing were to wait for the two significant construction projects in the Downtown to be completed and contain traffic disruptions to this limited area. During construction, for vehicular and pedestrian traffic on Marsh Street, a detailed traffic detour plan will be enacted to divert traffic around the bridge site while still providing access and parking to the businesses adjacent to the bridge. Once the construction and consultant contracts have been awarded and construction timeframes are set, a broader communication plan will be implemented to notify community members of project benefits and impacts. Previous Council or Advisory Body Action On October 16, 2018, the City Council appropriated an additional $1,406,160 in grant funding to match the total project amount allocated by Caltrans. Policy Context Per the October 2018 Financial Management Manual, Council approval is required for Public Projects that cost over $175,000. Public Engagement The bridge replacement was identified and included in the 2015-17 Financial Plan and identified as a Council Goal. Packet Pg. 76 Item 8 CONCURRENCE As components of the bridge replacement project, a new sewer siphon must be installed, and an existing water line will need to be re-routed across the new bridge. Proceeding into the construction phase of the project has the concurrence of the Utilities Department. This project has been developed in coordination with Caltrans. Caltrans concurs with this action by issuance of E-76 authorizing advertisement of construction documents for bids. ENVIRONMENTAL REVIEW On May 2, 2017, the City Council adopted a resolution certifying the Final Environmental Impact Report (EIR) for the Marsh Street Bridge Replacement Project (Attachment 3). Environmental permits have been secured with the Department of Fish & Wildlife, the Regional Water Quality Control Board, the Army Corps of Engineers and the State Historic Preservation Office. FISCAL IMPACT Budgeted: Yes Budget Year: 2019-20 Funding Identified: Yes Fiscal Analysis: In 2010, the City applied to the San Luis Obispo Council of Governments for State Transportation Improvement Program (STIP) for funds for the project and was awarded the funding. The project uses a combination of 89% Federal Highway Administration (FHWA) funding (specifically, Highway Bridge Program funding) and 11% matching funds through the City’s Local Revenue Measure (LRM). Currently, the total project budget of $6,559,047 is comprised of these two funds plus a portion from the Sewer Fund addressing the existing sewer syphon. FHWA Grant Funding:5,575,269$ LRM Matching Funds:722,335$ Sewer Fund:261,443$ Total Budget:6,559,047$ Currently Available Project Funding Sources Construction:4,475,543$ Construction Contingencies:447,554$ Construction Management:671,331$ Miscellaneous Costs:964,619$ Total for Project:6,559,047$ Current Project Budget:6,559,047$ Remaining Budget:-$ Project Costs Packet Pg. 77 Item 8 From the table above, the Miscellaneous Costs in the amount of $964,619 will be used for the extension of the TCE agreements, environmental permitting fees, final preparation of the construction documents for bidding and if needed, provide additional funds if the lowest responsible bid exceeds the construction cost estimate. Any grant funding unused upon the completion of the project will be returned to Caltrans. ALTERNATIVES Deny construction approval. The Council could choose to deny or defer approval for construction. Staff does not recommend this option. Should this be denied or deferred, the construction of the bridge replacement would be in jeopardy of loss of Federal funding. The FHWA could terminate the project entirely, resulting in the City having to reimburse FHWA the funding that has already been spent for design and right of way phases of project work.
