As-built drawings, warranties, guarantees, and operation manuals are provided to the owner during which project phase?

During the turnover phase of a project, as-built drawings, warranties, guarantees, and operation manuals are provided to the owner. This phase is critical as it represents the completion of the project and the handover of all relevant documentation and materials related to the project.

As-built drawings are essential because they reflect the actual constructed conditions of the project, which may differ from the initial design due to changes that occurred during construction. These documents ensure that the owner has an accurate representation of what was built, which is important for future maintenance or modifications.

Warranties and guarantees are also provided during turnover to assure the owner that the work performed meets agreed-upon standards. These documents protect the owner's investment by ensuring that any defects or issues that arise within a specified period will be addressed by the contractor or supplier.

Operation manuals are crucial for the owner's ongoing use and maintenance of the project. They provide detailed instructions on how to operate and maintain the systems installed, ensuring that the owner can effectively manage the facility moving forward.

In summary, the turnover phase is where all essential documentation is compiled and handed over to the owner, confirming that the project has been completed to specifications and providing the necessary information for its future operation and maintenance.
