As Built Survey

As-Built, also called ‘As Constructed’, surveys are usually produced at the end of the project and are used to illustrate where buildings, pavements, roads and features have been built. These surveys can also be carried out during the different stages of construction, to provide a point in time view.

As Built surveys are used to demonstrate to the building inspector that the project conforms to regulations. It can be a useful tool during a large project, to show what has been completed and allow for scheduling adjustments to be made. This type of survey can also be used by a contractor to determine payment schedules relating to different aspects of the build.
