SAN FRANCISCO MUNICIPAL TRANSPORTATION AGENCY DIVISION: Capital Programs & Construction BRIEF DESCRIPTION: Authorizing the Director of Transportation to execute Contract Modification Nos. 17 through 30 and ratifying Contract Modification Nos. 13 through 16 which were already executed by the Director of Transportation to (SFMTA) Contract No. 1251, Union Square/Market Street Station Utilities Relocation with Synergy Project Management Inc. These Contract Modifications increase the contract amount by $1,852, to $20,794, and extend the term of the Contract by 103 calendar days to 583 calendar days. SUMMARY: On December 7, 2010, the SFMTA Board of Directors awarded Contract No. 1251, Third Street Light Rail Program, Phase 2 Central Subway Union Square/Market Street Station Utilities Relocation, to Synergy Project Management, in the amount of $16,832, The Contract work included the relocation of utilities to accommodate the future Central Subway Union Square/Market Street Station structure. During execution of Contract work, the Contractor encountered various unforeseen conditions at multiple locations. Additionally, the SFMTA and private utility owners requested that the Contractor perform work activities not included in the original Contract. To date, Contract Modification Nos. 1 through 16 have been executed which increased the contract amount by $2,703, to $19,535, and extended the term of the Contract by 39 calendar days to 519 calendar days. Contract Modification Nos. 17 through 30, will increase the Contract amount by $1,258, and will increase the Contract term by 64 calendar days. Of this total amount, $880, will be reimbursed to the SFMTA via existing agreements with the private utility owners. The SFMTA and the Contractor were unable to come to a timely bilateral agreement. In order to expedite payment to the Contractor, SFMTA Project Staff decided to proceed unilaterally with these 13 Modifications. Due to the unilateral nature of these Contract Modifications, there remains a possibility that the Contractor may pursue additional compensation. ENCLOSURES: 1. SFMTAB Resolution 2.

PURPOSE: Requesting authorization to execute Contract Modifications Nos. 17 through No. 30 and ratification of Contract Modification Nos. 13 through 16 which were already executed by the Director of Transportation to (SFMTA) Contract No. 1251, Third Street Light Rail Program, Phase 2 Central Subway Union Square/Market Street Station Utilities Relocation, with Synergy Project Management Inc. for an increase of $1,852, to the contract and a contract extension of 103 calendar days. GOAL: Contract Modification Nos. 13 through 30 to SFMTA Contract No. 1251, are consistent with the SFMTA Strategic Plan in the following goal and objective: Goal 3 - Improve the environment and quality of life in San Francisco. Objective 3.3: Allocate capital resources effectively. DESCRIPTION: Project Background: The Central Subway Project (Project) is the second phase of the SFMTA's Third Street Light Rail Project, and will add 1.67 miles of light rail track north from the northern end of the new Third Street Light Rail at Fourth and King Streets to a terminal in Chinatown. The Project will serve regional destinations, including Chinatown (the most densely populated area of the country that is not currently served by modern rail transportation), Union Square, Moscone Convention Center, Yerba Buena, SoMa and AT&T Park. The Project will also connect BART and Caltrain (the Bay Area s two largest regional commuter rail services), serve a low auto ownership population of transit customers, increase transit use and reduce travel time, reduce air and noise pollution, and provide congestion relief. The public interest and necessity require the construction and operation of the Project to achieve such benefits. The Project will have four stations and connecting subsurface tunnels to provide direct rail service to the South of Market and Chinatown neighborhoods. The Project has been planned and located in a manner that will be most compatible with the greatest public good and the least private injury. Current Status of the Project: The construction contract for relocating utilities for the Yerba Buena/Moscone Station and the tunnel portal areas (Contract No. 1250) is completed. The construction contract to relocate utilities in the Union Square/Market Street Station location (Contract No. 1251) is substantially complete. The tunneling contract (Contract No. 1252) is progressing with construction activities approximately 29 percent complete. The final Contract for the stations and systems is in the bid procurement process. On December 7, 2010, the SFMTA Board of Directors adopted Resolution No , which awarded Contract No. 1251, Third Street Light Rail Program, Phase 2 Central Subway Union Square/Market Street Station Utilities Relocation, to Synergy Project Management Inc., in the amount of $16,832, and a contract term of 480 calendar days.

Due to the critical life safety of several of these utilities and the present occupancy of the property, it was clear that these facilities must remain active and undisturbed during construction activities. This Contract Modification compensates the Contractor for protection and support of these utilities. Examples of this protection/support work include rerouting of electrical lines to avoid active construction zones and slinging of piping to prevent possible deflection/breaking. 3. Mitigation of Hazardous Materials: During inspections a large steel reservoir was found to be containing hydraulic oil fluids. This reservoir was part of a previous elevator system which has since been removed from the property. This Contract Modification compensates the Contractor for costs incurred to both remove and mitigate the hazardous fluids as well as costs to remove the emptied tank. 4. Installation of Structural Support System for Existing Electrical Panels: In addition to the previously discussed existing utilities, extensive electrical infrastructure including, but not limited to, service lines, circuit breaker panels and electrical switchgear, was discovered within the subsidewalk basement. In order to proceed with Contract construction activities, an elaborate support system was required to allow for continued and undisturbed operation of this electrical equipment. This support system involved temporarily supporting the electrical panels from above. This was achieved by installing a structural steel beam underneath the panels and welding this beam to the existing structural sidewalk beams with two vertical steel members. Additionally, plastic and

20 plywood was used to ensure that moisture would not be able to come in contact with any electrical service equipment. 5. Hand Demolition and Excavation Required Due to Confined Working Environment: Due to the limited working space within the subsidewalk basement demolition and excavation activities are hampered due to the inability to use heavy equipment. This Contract Modification compensates the Contractor for the decreased productivity due to his limited equipment selection. 6. Modified Micropile Installation Procedures: As part of a continued effort to minimize any disturbances to the aforementioned existing utilities, the Contractor and his micropile installation Subcontractor devised a modified pile installation procedure which minimized movement of the auger and directed spoil outfall. This modified approached involved the installation of a fixed hollow steel tube which acted as a guide for the auger as well as a chute for the drilling spoils. This Contract Modification compensates the Contractor and his Subcontractor for the additional costs related to procuring the steel guide materials, installation and securing the guide and hand removal of the directed spoils. 7. Changes to Secondary Closure Wall: Due to the congestion of existing utilities within the footprint of the secondary closure wall (to be installed per original CN 1251 Plans), several small changes were made to the wall design. These changes consisted additional forming for block outs, wall jogs and service meters. Additionally, these changes involved the installation of a salvage manhole and the blocking out of a small area of the subsidewalk basement as required to allow for access after the installation of controlled density fill (CDF) in the voids surrounding newly installed utility conduits. 8. Modified Utility Conduit Installation Schedule: Due to the changes discussed in Item No. 7 (above) there is an area in the subsidewalk basement in which the newly installed conduit will not be supported by CDF (resulting from the required block out). In these areas the Contractor is required to install additional racking systems to prevent conduit deflection and/or damage. This Contract Modification compensates the Contractor for costs related to these additional racking systems. 9. Equipment Standby and Decreased Production: This Contract Modification also compensates the Contractor for equipment standby and subsequent decreased production resulting from the multitude of differing conditions encountered. Note that any work required to implement the changes discussed above yet omitted from the above scope of work shall be considered incidental to the work being compensated within this Contract Modification. Such omitted work, if any, shall not warrant any additional costs beyond the costs contained in this Contract Modification. Lastly, this Contract Modification compensates the Contractor for additional time related overhead (TRO) costs resulting from the 35EA calendar day Contract extension contained herein. This compensation represents a complete and final compensation for all of the Contractor s additional indirect costs.
