Mechanical As-Builts

As-builts are used to show the finished condition of the work as it was actually constructed and accepted. The as-builting task is a usual and important requirement of construction contracts and contract language puts this work upon the contractor. The process requires that any change that modifies the original design be incorporated by drafting the change upon one set of contract documents earmarked just for that purpose. Generally, changes are recognized or authorized within contract-related documents that are prepared during the course of work. Change documentation may include incorporation of a contractor's Notices of Change that are acknowledged as having merit by the construction management, change orders, field orders and non-conforming work that was accepted "as-is" or mitigated by other means. It would also include value engineering agreements, certain T&M authorizations and, sometimes, responses to RFIs. Documentation may also include the incorporation of addenda that were issued during the bid cycle, when conformed drawings were not issued by the owner. To be complete, ABs would also require that the contractor record a change for which no authorizing document exists.
