Purpose of As-Built Surveys - As-Built surveys are used to show the finished condition of the constructed work. The as-built documentation is an important requirement of construction contracts. The process of signing off work and adoption requires that any change that modifies the original design is incorporated by drafting the change upon one set of contract documents, earmarked just for that purpose.
As-Built surveys are prepared most often at the end of construction to satisfy the client and end user. In the case of As-Built drainage this will be the local water authority. They help to determine that all improvements on a site were constructed in compliance with the specifications as outlined by the engineer during the design process. This survey usually reflects all building, kerb and parking features, utilities, sewers, storm drainage facilities and other structures as needed.
The Importance of As-Built Surveys - As a development project and its construction progress, the work scope often changes. Beyond executing the change in the field, changes need to be documented to show what was actually constructed. Hence, the owner usually requires a final record to show all changes or, more specifically, any change that modifies the tangible portions of the completed work. The end product of this effort is what we call 'As-Built' drawings.
