1-15 AS-BUILT DRAWINGS AND AS-CONSTRUCTED DRAWINGS
PRACTICE STATEMENT: As-built/As-constructed drawings should be specified
as a contract/project deliverable and should be prepared as soon as practicable,
and the information recorded to aid in future locates and construction. This
updated information should be circulated among the pertinent parties involved
in the project as soon as practicable, (i.e. municipalities, utilities, public works
authorities, and UCCs) and those parties should update their records
accordingly. In this way, utility records should be maintained as current as
possible.
PRACTICE DESCRIPTION: As-built and as-constructed drawings should be
valid. The information on as-built and as-constructed drawings are to help with
future locates and construction. All appropriate parties involved (i.e.
municipalities, utilities, public works authorities, utility coordinating
committees, and so on) should receive any information updates on the project
and they should update their records accordingly. This practice is a way of
keeping utility records as current as possible.
Installations should be in accordance with the approved construction plans. It is
essential to approve, document, and record on the as-built and as-constructed
drawings any deviations to these plans. It is also important to retain the
drawings and make them available for future projects.
As-built and as-constructed drawings should have the following features:
Ÿ Any deviations in construction from the approved design
Ÿ Level of accuracy in the horizontal and vertical locations of the underground
utility
Ÿ Methodology used to measure the accuracy (e.g., geodetic survey) ) or
relationship to topographical/physical features at the time of construction
Ÿ Date the drawings were prepared, and
Ÿ Method of construction (e.g., directional drilling)
CURRENT PRACTICE: All as-built and as-constructed measurements should
be ready to be submitted. These measurements should be available upon
completion of construction and prior to the final acceptance of the installation
by the owner.
The measurements should note any deviations in the following areas:
