Which role is responsible for marking up As-built drawings?

The role responsible for marking up As-built drawings is typically that of the Assistant Superintendent. This is because the Assistant Superintendent is closely involved in the day-to-day operations on the site and works directly with the construction crew to oversee the progress of the work. They are tasked with ensuring that the construction is executed as per the plans and specifications, which necessitates their deep understanding of all changes and modifications that occur during the construction process.

As-built drawings are crucial as they reflect all alterations or modifications made during the construction, which may differ from the original plans. The Assistant Superintendent's familiarity with these details enables them to accurately mark up these drawings to capture the reality of the project as it develops, documenting any deviations from the initial designs. This documentation is essential for future reference, project assessments, and compliance with regulatory standards.

Other roles, such as the Project Manager or Project Engineer, may be involved in the overall planning and management of the project, but they might not have the same level of hands-on interaction with the construction process and the specific changes made during execution. The Site Foreman may also oversee crews and operations but is generally more focused on immediate tasks rather than the comprehensive documentation of as-built conditions.
