Postconstruction

Postconstruction refers to the phase of a construction project that follows the completion of physical works. It focuses on ensuring the project meets its design intent, operates safely, and can be managed effectively over its lifespan. The phase typically includes closeout activities, commissioning and systems testing, defect resolution, and formal turnover to the owner.

Key activities commonly associated with postconstruction include final inspections and regulatory approvals, the preparation and correction of punch lists, and the collection of warranties and lien waivers. It also involves assembling operation and maintenance manuals, as-built drawings, and maintenance schedules, along with training for facility staff. Commissioning and performance verification often extend into this period to confirm systems operate as designed.

Documentation and data management are central in postconstruction. Reliable records, digital models or facility management databases, and clear transfer of control responsibilities support future operations, maintenance, and renovations. A post-occupancy evaluation may be conducted to assess occupant satisfaction, energy performance, indoor environmental quality, and overall building performance.

Stakeholders typically include the owner, general contractor, design professionals, commissioning agents, and the facilities management team. The process aims to safeguard safety, reliability, and lifecycle cost efficiency while enabling a smooth transition from construction to operations. Common challenges include incomplete documentation, delayed defect resolution, misaligned warranties, and coordinating turnover with occupants.
