Conduits – (Shared Trench) 63 TS-085: Trenching & Conduit for Underground Distribution Cable Networks PURPOSE This Technical Standard specifies the standard trench, conduit, retaining walls and Civil works requirements for a new or upgraded installation that will be a component of SA Power Networks‟ distribution network Once the scope for a trench, conduits, retaining walls and Civil works is determined, then this technical standard will assist the Customer in the Civil component of electrical works/network extension The construction could encompass a network extension, PLEC projects, SA Power Networks‟ capital works, specific arrangements or customer works These works could be on private property or on a public road verge This standard will assist in clarifying the responsibilities of customers regarding agreements, approvals, construction requirements and the SA Power Networks requirements for “Civil Works Compliance” 2.0 SCOPE The specification in this technical standard is applicable (but not limited) to all parties involved in the activities of trenching, conduit installation, retaining walls and Civil works associated with the underground installation or alteration of distribution cable networks This technical standard is to cover all underground trenching and conduit installations; however, section 17.0 is an additional requirement for applications to 66kV underground networks The appendices at the end of this document provides more detailed information on trench arrangements, Civil Works notification and Civil works compliance and cable location markers The “Electricity (General) Regulations 1997”, other statutory authority requirements, AS/NZS standards and the Building Code of Australia (BCA) are the basis of TS-085 For any situation that is not covered in this standard, the requirement of AS/NZS 3000 applies There may be additional requirements and specifications that are project specific For further assistance/information concerning this technical standard, please contact the relevant SA Power Networks‟ Manager This technical standard is available at the SA Power Networks websites below: Intranet website (Internal) Internet website (External) 3.0 GRACE PERIOD The maximum grace period acceptable by SA Power Networks for implementing this Standard is months from the date of publication All projects that are not in receipt of “Specification Compliance” at the revised date of issue for this technical standard will need to incorporate the latest requirements This is applicable to both the design and construction phases of the project The validity period for a “Specification Compliance” is 60 days On the expiry of a “Specification Compliance”, any specification change without a documented exemption must be incorporated into the design and construction of SA Power Networks infrastructure TS-085 Issue: 03/09/12 Authorised: Jehad Ali Date: 03/09/12 Page of 73 The use of this Technical Standard is subject to the
