Quarterly Review Report – 3rd Quarter 2015Communication Work: Approximately 80% of all Factory Acceptance Tests were completed. Network FieldInstallation Acceptance Testing (FIAT) at 63rd Street Station is ongoing. Installation of Copper and Fiber Optic cables at 72nd and 96th Street Stations is ongoing. Approximately 80% of all radio antenna cable was installed in tunnels between 63rdStreet and 96th street, including 63rd Street and 72nd Street Stations.Traction Power Work: Completed delivery of traction power equipment in all three substations and continuedinstallation of equipment at 72nd Street Substation.CRITICAL ISSUESDelay in Construction of Entrance #1 (at 69th Street) of 72nd Street Station (C26011): The Project needs to complete Entrance 1 work by September 2016 to maintainProject RSD. Contractor has implemented an agreed mitigation plan to recover previouslylost time with the Entrance #1 work. Contractor's schedule is very aggressive but they havekept the overall completion of the entrance, which is driving the completion of the station,essentially on schedule.Mitigation: Mitigation includes working second shift, extended hours and weekend workand exploring opportunities to increase work hours on certain upcoming activities withinthe building.Contractor progress shows the September 2016 date can be met. Rock removal at the topof the escalator incline was a along lingering problem requiring additional mitigation,however, this rock was completely removed on July 17. The lower portion of the escalatorincline concrete work is ahead of planned schedule. Street work remains about two weeksahead of schedule. Contractor will complete structural shell two weeks later than planned,however, contractor has done other work in parallel so the MEP work can start on 22 Oct15 as scheduled.Testing & Commissioning (T&C) Requirements: The Project recognizes that T&Cresource requirements, if not properly planned for, represent a major risk to the schedule.As a result, the Project has been focused over the last several months in developing andimplementing a risk mitigation strategy to reduce the level of this risk.Mitigation: As reported last quarter, MTACC’s Chief of Quality and System SafetyCertification was assigned the added responsibility of leading the Testing andCommissioning work. He has commenced with this assignment. The Project is exploring(Quarterly Report July, August, Sept.’15)Second Avenue Subway – Phase 1(16.0.1)5

Quarterly Review Report – 3rd Quarter 2015ways that MTACC can best manage T&C with NYCT resources. Ongoing meetings havebeen taking place between senior management at MTACC and NYCT to develop aneffective approach which might include:o Developing a scope document that provides both MTACC and NYCT with thefull scope of T&C work. This would include identifying all the areas to beapproved as well as a comprehensive list of all equipment to undergo T&C. Thiswould assist both parties in better understanding the need to effectively plan andutilize NYCT resources.o Dedicated NYCT resourceso Locating NYCT resources at the siteo Creating a database for an observation listo Upgrading tools to enhance observation list development. This would includeipads that designated individuals would use to record their observations duringstation visits. The observations would be immediately available to key Projectpersonnel for disposition as well as posted on the EDMS data baseo Hire Code Consultant to augment NYCT Code Complianceo Conduct bi-weekly meetings with Code Compliance personnel who havecommitted to making weekly visits to the Project Stations to identify items torectifyFacility Power: There is the risk that facility power energization at all new stations maynot be available in time to support planned Testing and Commissioning activities. Delayin the availability of permanent power will have a direct impact on project contingency.Mitigation: In the Second Quarter 2015, the project developed detailed schedules thatshow completion of facility power rooms prior to the end of December 2015. The Projectcontinues to closely monitor progress of the latest schedules for the facility powerinstallation. In the Third Quarter 2015, each of the three stations experienced problemsthat may delay permanent power beyond the December 2015 date.72nd Street: The most significant problem with maintaining the schedule for facilitypower installation at 72nd Street Station has long been the completion of Ancillaries 1and 2. Delays in construction of facility power rooms at Ancillary 1 Building, notably thepresence of the concrete shoring that is preventing power equipment from being movedinto the rooms, have tentatively moved permanent power from December 2015 to end ofFebruary 2016. The project is working with the contractor to improve this date to January2016.86th Street: All equipment is delivered to the site including the Low Voltage Gear, DCequipment and Busduct that was reported as delayed in the last quarter report.
