'''As-built Survey'''<br>Throughout the construction process, it is sometimes necessary to deviate from the intended design of LID features and adapt the design to on-site conditions. The completion of a post-construction as-built survey is a standard operating procedure for engineering projects that captures and changes that were made to the feature’s design during construction. Survey Steps:*Use the same datum as the pre-engineering survey*If a pre-engineering survey is not available, use a reference feature as the datum*Include data on critical feature elevations and existing utilities, such as:**Inverts of newly installed pipe**Vertical and horizontal bends in pipes**Existing public utilities**Existing private utilities**New and existing structures (e.g. catchbasins, manholes, chambers, etc.)*Identify the type, diameter, and material of exposed utilities Inspection Points:*Datum matches the pre-engineering survey or selected reference feature*Data provided in as-built survey matches the as-built standards of the City
