Which milestone marks the date when the building can be occupied for its intended use, with minor work still remaining?

• A. Final completion
• B. Substantial completion
• C. Practical completion
• D. Acceptance

Answer: (B)

Substantial completion is the milestone when the project is ready for its intended use, even though minor tasks may still remain. At this point the owner can occupy the building and begin its normal use, while a punch list of small items is completed afterward. This distinction matters because occupancy and the start of certain protections or warranties are tied to substantial completion, not to final completion. Final completion means all work is finished and closeout items are fully resolved, which comes later. Practical completion is often described as the point at which all major works are finished and the project is substantially usable, but the exact trigger can vary by contract; occupancy is typically associated with substantial completion. Acceptance refers to the owner formally accepting the work, which is not the milestone that allows occupancy.
