What is the milestone called when the data center is ready for commissioning, and is also the name of a meeting held about six weeks before commissioning?

• A. Substantial Completion
• B. Handoff to Commissioning (H2C)
• C. Integrated Systems Testing (IST)
• D. Level 1 (L1)

Answer: (B)

In data center projects, a formal handoff to the commissioning phase marks the point when everything is ready to begin testing, and this milestone is named Handoff to Commissioning. It also serves as the pre-commissioning coordination meeting, typically held about six weeks before actual commissioning. The purpose is to lock down readiness: ensure all major systems are installed and documented, warranties and permits are in place, test plans and resources are prepared, and roles and the schedule are agreed. This setup lets the commissioning team run structured tests of power, cooling, network, rack layout, and full system integration without last‑minute surprises. Substantial Completion is a broader construction milestone indicating most work is finished and the space is usable, but it doesn’t specifically denote readiness to start commissioning or a pre-commissioning meeting. Integrated Systems Testing is a testing phase within commissioning focused on how subsystems work together, not the pre-commissioning handoff itself. Level 1 doesn’t align with the standard data center commissioning milestones or the pre-commissioning meeting name.
