Examples of Practice:
1. In planning the designer should obtain a list of affected facilities and
contact the facility owner for design and encroachment information. The
design should include, as specified by the owner, marker locations for
each encroachment during and after construction.

2. In the installation of additional underground facilities, the designer should
obtain a list of affected facilities, and should include a detailed marker
system to effectively mark the underground facilities. Examples of a
detailed marker system include tracer wires on non-metallic facilities and
electronic or surface markers for facilities at excessive depths.

Benefits: The design includes provisions to aid in future locates. In addition,
an effective marker system will assist facility owners or first responders to
an area involving more than one underground facility or an incident near
underground facilities.

1-9: Follow All Applicable Codes, Regulations, and
Owner Standards

Practice Statement: When planning and designing the installation of new
or replacement facilities, the designer should ensure compliance with all

• federal and provincial statutes, regulations, codes, standards, and
guidelines
• municipal by-laws
• owner standards, and
• Best Practices.

Practice Description: The designer of a facility project should consider
standards and practices and comply with codes, and regulations applicable
to that particular facility, and adjacent facilities. As a matter of practice the
designer should circulate the design to the appropriate stakeholders within
the right-of-way to ensure compliance. Stakeholder review is facilitated
by the level of detail which accompanies the design. Regulations, codes,
standards and other design documents generally specify depth of cover, and
horizontal and vertical clearances between adjacent facilities.
The designer should consider the protection and temporary support of
adjacent facilities, and any interference with existing cathodic protection and
grounding systems. Consequently, the designer has to provide specifications
on safety measures to be taken and procedures for emergency notification
and repairs in the case of any damage to an adjacent facility. Designers and
facility owners should make all parties aware of new and revised standards
and codes that may affect the project.
