What is the purpose of as-built or redline drawings?

The purpose of as-built or redline drawings is to serve as a record of actual installation. These drawings provide an accurate depiction of the construction after all changes have been made during the project. They reflect the final state of the project, including any modifications or adjustments that occurred during construction. This is crucial for future reference, maintenance, and potential renovations, ensuring that anyone looking at the drawings can understand what was actually built rather than what was originally planned.

The incorrect options highlight aspects not typically associated with as-built drawings. Future project plans are indicative of pre-construction documents, leaving no connection to the finished state of the project. While as-built drawings may occasionally be referenced during final inspections, their main function is not in the inspection process itself. Furthermore, they do not replace contract drawings but rather complement them by providing real-time updates and details on how the project was executed compared to those initial plans.
