Which party is responsible for Construction Phase Schedule Integration?

• A. Contractor
• B. Shared
• C. CxA
• D. Owner

Answer: (C)

Construction Phase Schedule Integration is about weaving commissioning activities into the project timeline so tests, verifications, startups, and turnover milestones happen in the right order. The CxA is responsible because they coordinate the commissioning plan across all trades, ensure testing and sequence dependencies are reflected in the master schedule, and work with the contractor and owner to align procurement, installation, and startup with performance verification and occupancy readiness. The contractor provides the construction schedule and sequences, but the CxA maintains the commissioning logic and ensures it is embedded in the schedule, guaranteeing that acceptance criteria are met before handover. While owners and contractors contribute, the responsibility to integrate and preserve the commissioning timeline rests with the CxA.
