Standard S250-11 – Mapping of underground utility infrastructure

Application of this new standard can help improve accuracy and reliability in locating & mapping underground infrastructure, as well as improve record keeping. It can be applied to proposed, existing, abandoned-in-place, retired or reserved-for-future-use situations.

During the planning or preliminary design phase of a project, all available information should be gathered from the facility owners/operators, including maps of existing, abandoned, and out-ofservice facilities, as-built of facilities in the area, proposed projects, and schedules of work in the area.
