Commissioning Manager - Mission Critical

Commissioning Manager Data Centers

GCON is seeking an experienced Commissioning Manager to oversee the planning, execution, and delivery of full L1L5 commissioning programs for complex, hyperscale mission-critical projects. This role is ideal for a seasoned professional from a general contracting background who excels at managing multi-disciplinary commissioning teams, complex MEP systems, and high-stakes project delivery across all commissioning levels.

As the Commissioning Manager, you will own the end-to-end commissioning process from preconstruction strategy through L5 integrated systems testing and final owner acceptance. You'll coordinate across project teams, trade partners, clients, and third-party commissioning agents to ensure all systems perform to the highest standards of reliability, redundancy, and compliance at every commissioning level.

Key Responsibilities

* Lead the full L1L5 commissioning program for multiple large-scale hyperscale data center projects, encompassing mechanical, electrical, plumbing, controls, and specialty systems across every phase of commissioning rigor.

* Develop and implement comprehensive commissioning plans, schedules, and level-gate workflows for all phases L1 component verification, L2 pre-functional checks, L3 functional performance testing, L4 integrated systems testing (IST), and L5 full facility/IT load testing through final turnover.

* Define level-entry and level-exit criteria for each commissioning phase, ensuring no system advances without meeting documented readiness standards.

* Manage and coordinate multi-disciplinary teams including project managers, superintendents, subcontractors, and third-party commissioning agents aligning all stakeholders to commissioning level milestones and critical path gates.

* Oversee risk management and recovery strategies for schedule, system readiness, and critical path impacts at each commissioning level, with particular focus on protecting L4/L5 integrated testing windows.

* Ensure quality assurance, code compliance, redundancy requirements (N, N+1, 2N), and system reliability are validated through structured level-by-level progression.

* Lead client-facing meetings and gate reviews at each commissioning level, providing technical expertise, issue logs, and level-completion reporting to owners and third-party agents.

* Partner with preconstruction teams to develop L1L5 commissioning strategies during design review, anticipating system sequencing challenges and optimizing testing workflows for hyperscale build schedules.

* Drive continuous improvement by standardizing level-gate documentation, integrating digital commissioning tools, and mentoring project teams on hyperscale commissioning best practices.

* Manage final L5 acceptance and project turnover, including complete commissioning documentation packages, owner training, and lessons learned across all commissioning levels.

Required Skills & Experience

* 810+ years of commissioning experience on mission-critical or data center projects with a general contractor, including hands-on delivery of L1 through L5 commissioning scopes.

* Demonstrated expertise leading L3 functional testing and L4 integrated systems testing (IST) on hyperscale or enterprise-scale data center facilities.

* Proven experience managing L5 full facility acceptance testing under IT load for Tier III/IV or equivalent hyperscale environments.

* Bachelor's degree in Construction Management, Engineering, or a related technical field.

* Deep knowledge of MEP and critical infrastructure systems commissioning, including level-specific test procedures, deficiency tracking, and resolution workflows.

* Strong leadership skills, with the ability to align cross-functional teams and third-party commissioning agents across concurrent commissioning levels on fast-track schedules.

* Ability to analyze, troubleshoot, and resolve complex system interactions particularly during L4 IST scenarios under tight deadlines.

* Excellent client-facing communication skills, with experience presenting level-completion reports and commissioning status to owners and technical stakeholders.

Preferred Qualifications

* Direct experience delivering L1L5 commissioning programs for hyperscale clients (e.g., AWS, Microsoft, Google, Meta) at gigawatt-scale campus or multi-building facilities.

* Familiarity with hyperscale owner commissioning standards and how they map to internal L1L5 level structures.

* Proficiency with Primavera P6, Procore, BIM 360, and commissioning management platforms capable of tracking level-gate status across large systems counts.

* Working knowledge of ASHRAE Guideline 0, NEBB, and BCA standards as they apply to structured commissioning level progression.

* Experience managing concurrent L3/L4 testing across multiple buildings or power blocks within a single campus program.

The GCON Way

* Work with a forward-thinking, collaborative team that embraces technology and innovation.

* Be part of a leading construction manager building…
