An as-built survey is a detailed post-construction survey that documents the location of completed site improvements. Depending on the project scope and municipal requirements, the survey may include features such as storm drainage systems, sanitary sewer, water utilities, detention ponds, buildings, pavement, sidewalks, and other infrastructure. Keystone Land Surveying prepares as-built surveys in accordance with the applicable standards and submittal requirements of the governing municipality or jurisdiction to support permitting, inspections, and project closeout.
