OverviewThe Senior Commissioning (Cx) Manager is responsible for assignment-level planning, coordination, readiness verification, and delivery of the Mission Critical (MC) commissioning program on large, complex, or multi-project assignments across the Level 0-5 lifecycle, in accordance with the Commissioning Execution Standard (CxES) and applicable client requirements. The role leads Suffolk's commissioning responsibilities through project closeout and coordinates Suffolk's preparation, participation, issue resolution, and turnover support during client- and Commissioning Agent (CxA)-led commissioning activities.
The Senior Commissioning Manager typically serves as the Project Lead Commissioning Manager on large, complex, multi-building, or elevated-risk assignments and may direct one or more Commissioning Managers and supporting commissioning personnel. Assignment is based on project requirements, individual capability, and organizational needs. Organizational reporting remains through the MC Commissioning Program Manager.
The role preserves the independence and integrity of commissioning verification while supporting project delivery objectives, and carries an expanded responsibility to develop commissioning personnel and support continuous improvement of the Mission Critical Commissioning Program. Between project assignments, the Senior Commissioning Manager may support Preconstruction, pursuits, Technical MEP, commissioning planning, program development, or other program priorities.
