S250-11 (R2016)

Overview

Until recently, accurately recording the presence and location of utility infrastructure was not formally required, nor carried out in a consistent manner. This standard helps ensure that accurate information about underground utility infrastructure at or below grade is captured and available for future projects.

• CSA S250 helps municipalities and their service providers to:Increase accuracy and reliability, and enhance record keeping in locating and mapping underground infrastructure

• Improve the safety of company and contractor employees, and the general public by reducing the potential for utility hits or strikes and service interruptions

• Reduce utility design costs by sharing accurate and complete utility records in a timely fashion among key stakeholders during the planning, circulation and permitting processes 

Preface

This is the first edition of CSA S250, Mapping of underground utility infrastructure.

Scope

1.1 General

This Standard specifies mapping requirements for the recording and depiction of underground utility infrastructure and related appurtenances at or below grade. This Standard does not apply to utility infrastructure that is normally above grade (e.g., overhead wires, pole-mounted transformers, antennas, and dishes).

1.2 Application

This Standard applies to proposed, existing, abandoned in-place, retired, or reserved for future use, underground utility infrastructure. This Standard applies to the generation, storage, distribution, and use of mapping records to ensure that underground utilities are readily identifiable and locatable. Application of this Standard will ensure that accurate information about the location and nature of the underground utility infrastructure is captured and available for future projects.
