Mechanical Completion Substantial Completion and Final Completion Sample Clauses

This clause defines the key project milestones of mechanical completion, substantial completion, and final completion in a construction or engineering contract. It typically outlines the criteria and procedures for certifying when the work is mechanically complete (all systems installed and ready for testing), when it is substantially complete (suitable for intended use, with only minor items remaining), and when it is finally complete (all contract requirements fulfilled, including punch list items). By clearly delineating these stages, the clause provides a structured process for project handover, helps manage expectations, and determines when responsibilities and risks transfer between parties.
