Discussion included March 2015 unanticipated work related to the SAS tower anchor rod grouting issue and the continual evaluation of COS budget impact for the current fiscal year. It was noted that the COS budget risks ahead include the on-going METS A&E rod investigation. Dan McElhinney said he would return next month with a COS update and forecast of SAS tower anchor rod investigation capital outlay and COS costs. The Department is currently tracking the $41.4M budget. There is no action required by the POC at today’s March meeting. b. Risk Management Update** Rich Foley, SFOBB Risk Manager, presented a risk management process update. An extensive risk assessment is underway to include scope, schedule, and capital outlay/support cost impacts for a range of project risks to develop an updated risk register and a review of the overall program funding and expenditures for the current and future fiscal years. Challenges going forward included project close-out, ongoing SAS, YBITS2, Marine Foundations and 504/288 demolition work. o Pier E3 will have a separate risk register including an updated estimate for the conventional method of marine foundation removal and recognizing the implosion risk opportunity. o The Department will focus on the mitigation effort moving forward with risk assessment process. The approach to assessing risks will be adjusted to account for various variables including optimistic and pessimistic potential outcomes. Action Dan McElhinney to provide a COS update and forecast of SAS tower anchor rod investigation CO and COS next month. The Chair asked for the Department to look at possibilities within the existing overall Toll Bridge Program budget to address risks due to unanticipated work.

Brian Maroney confirmed the recent testing was beyond contract specifications and the mechanical testing results are all within contract compliance. The Chair requested for Caltrans to perform investigation of the current condition of the anchor rods through ultrasonic testing (UT) inspection. Will Kempton and Malcolm Dougherty concurred with the statement. The Chair inquired if the micro-cracks could lead to fracture, Brian Maroney did not expect the micro-cracks to propagate. Brian Maroney will return in the next month with more information. The Chair asked if there was water at the tower when a rod was removed in 2013 and if any corrosion was observed. Bill Casey, Caltrans SAS Resident Engineer, confirmed the rods were in standing water but no corrosion was observed. The Chair inquired about dehumidification and other techniques to keep the holes dry. Brian Maroney discussed the various options to keep the holes dry. The Chair inquired if the Peer Review is involved in the review of the tower seismic anchor rods. Brian Maroney responded he would like them to be on board as soon as possible and has a proposal in process to do so. Will Kempton asked for more information and actions taken in regards to the missing QA documents. Will Kempton requested if the residue and stains on the structure could be cleaned up so future observations would be more noticeable. Bill Casey confirmed this could be done. Malcolm Dougherty concurred with this request. Malcolm Dougherty summarized his Action Caltrans Construction/METS to perform investigation of the current condition of all tower anchor rods through UT inspection in response to the Chair’s request.

These permits were originally issued in 2001, shortly after the approval of the final Environmental Impact Statement for the project. These permits and authorizations have been amended on numerous occasions throughout the life of the SFOBB project. In the interest of keeping these permits current, the attached table outlines the permits and authorizations by agency and the current expiration dates. Several of the permits have been issued for the life of the project. 1 of 1 Item 4c_Memo-EastSpanPermits-17Apr15-v0.doc Project Permits and Expiration Dates San Francisco-Oakland Bay Bridge (SFOBB) East Span Seismic Safety Project (SFOBB Project) The following table shows the environmental permits that have been issued to the SFOBB Project from state and federal regulatory agencies and their expiration dates – if included.

The contract award process is still pending as of the preparation of this summary. The Department, with concurrence from the PMT, recommended on April 1 for TBPOC approval the Pier E3 Demolition CMGC project proposed capital outlay budget for contract allotment and an identified amount in the risk reserve. This final contract budget will be based on a work items estimate from the contractor, and estimates for supplemental work, state furnished materials, risks and contingency to complete the E3 demolition. This proposed contract budget will be taken from the existing TBPOC approved forecasted budget ($107.1M) for the Marine Foundation contracts, per the 2014 Toll Bridge Seismic Retrofit 4th Quarterly Report (released February 2015). While the risk of incomplete implosion underwater debris removal and/or permit non-approval for implosion activities as contained in the Risk Registry have a low probability, the Department wishes to point out that the additional work and 1 of 2 Item 5b_Memo-E3_17Apr15-v1.doc Memorandum resultant schedule delays if these risks occur may impact the contract cost significantly. Since April 1, the Department has progressed in resolving costs with the contractor as per the CMGC procurement process and remains on schedule for a Contract Approval in April 2015. Pier E3 Demolition Underwater Implosion Plan Permit Update - Elevating Issues: At the request of the TBPOC, a review of the previous resolution process found that the “Tri-Agency group” was formed during early construction permitting in the early 2000s to advance issues of multiple interest that may arise to its member agencies (the former Business, Transportation and Housing Agency, Natural Resources Agency, California Environmental Protection Agency). The “TriAgency group” process was last initiated over a decade ago. Caltrans staff is currently working with the California Department of Fish and Wildlife (CDFW) to determine the need to mitigate for the potential take of state threatened longfin smelt. Any delays in decisions from CDFW may impact the Pier E3 contract schedule delaying work up to a year. Caltrans staff has drafted an issue memo for a potential discussion between the Secretaries of Transportation and Resources agencies by early May 2015 as needed. - Permit updates: Caltrans staff has submitted application packages to all state and federal regulatory agencies with jurisdiction over the proposed Pier E3 removal. Agencies include: - National Oceanic and Atmospheric Administration/National Marine Fisheries Service - U.S. Army Corps of Engineers - U.S. Fish and Wildlife Service - U.S. Coast Guard - California Department of Fish and Wildlife - San Francisco Bay Conservation and Development Commission - Regional Water Quality Control Board Permits are expected by July 2015. Permit non-approval for implosion activities will result in additional contract work and schedule delays that will impact the contract cost significantly. 2 of 2 Item 5b_Memo-E3_17Apr15-v1.doc Memorandum TO: Toll Bridge Program Oversight Committee (TBPOC) DATE: FR: Dan McElhinney, Chief Deputy District 4 Director of Caltrans / Brian Maroney, SFOBB Project Chief Engineer , Caltrans RE: Agenda No. - 5c1 April 10, 2015 Item- Self-Anchored Suspension Span (SAS) Project Update Recommendation: For Information Only Cost: Potential cost impacts to be determined.

The design team, the construction team and the TBSSPRP are satisfied that the final conditions of the construction meet or exceed the requirements of the project. To fully meet the 2 mm clearance requirements based upon dynamic structural analyses detailed field measurements were conducted followed by repositioning of anchor rods or cutting material from the anchor plate at necessary locations. As a result, a total of 41 rods were adjusted and in one case a plate was cored in order to meet the 2mm clearance requirements.
