The CS179 ESA Systems Facilities Package CM team was assisted in effectively establishing and managing all potential field and scope changes. Responsibilities included maintaining an inventory of all potential changes, leading construction modification meetings, and collaborating with stakeholders such as Program Executives, Construction Managers, General Engineering Consultants (GEC), Project Engineers, Estimators, Schedulers, Legal and Procurement teams, and Contractor representatives to successfully resolve potential changes and issues. Additional responsibilities involved developing, tracking, and maintaining a Testing dashboard to capture Factory Acceptance Tests (FAT), Local System Tests (LST), and Integrated System Tests (IST). As Technical Director (Tracking & Reporting), the Change Management Group (CMG) was directed to establish, maintain, track, and coordinate critical issues and potential change orders within the East Side Access Program. Responsibilities included working with the Program Management Organization (PMO) analytics team to identify and track critical issues related to individual contract milestones and incremental integrated systems testing (IST). Moreover, overseeing the development of CPM schedules using Primavera 6 was crucial for capturing, managing, analyzing, and tracking critical issues from inception until resolution. Preparing and monitoring Key Performance Indicators (KPI) dashboard for the East Side Access (ESA) program ($11 Billion) monthly provided valuable insights for project stakeholders. For CS179, MCSS worked on the Systems Package 1 – Facilities Systems contract ($600 Million) within the East Side Access (ESA) program. Their responsibilities included analyzing the contractor’s schedule, preparing monthly progress reports, analyzing milestones, longest paths, delays, cost and man-hours, and preparing Time Impact Analysis (TIA) reports on field changes and owner-initiated changes.
