Civil Services | Underground Civil Utility Packages

Underground Services NSW

SCE Corp reviews suitable underground civil utility construction packages across Sydney and NSW, including stormwater, sewer, conduits, pits, trenching, service interfaces and associated reinstatement, subject to issued requirements, site conditions, authority interfaces, licensed-party responsibilities, approvals, safety, programme and commercial fit.

A controlled pathway for underground services enquiries

Underground civil works may involve trenching, bedding, pipework, conduits, pits, chambers, crossings, service protection, backfilling, compaction, testing interfaces and reinstatement. SCE reviews the current drawings, specifications, service information, authority requirements, access, excavation conditions, traffic and environmental controls, work windows, inspections and handover requirements before confirming an accepted construction package.

SCE's principal role is construction delivery and practical coordination for the agreed civil works. Utility design, network-owner requirements, locating by appropriately qualified providers, regulated electrical or gas work, specialist testing, engineering acceptance, certification, utility connections and authority approvals remain with the appropriately appointed licensed, qualified or authorised parties.

Use the two direct service pathways below for new underground services or overhead-to-underground conversion work, or provide the available project information through the SCE enquiry page for an initial construction-fit review.

Installation of New Services

Review suitable new stormwater, sewer, water, conduit, pit, trench and associated civil installation packages where the design, authority interfaces and responsibilities are sufficiently defined.

Undergrounding Overhead Services

Review suitable civil workfronts for relocating overhead services underground, including trenching, conduits, pits, crossings and reinstatement coordinated with the responsible utility and licensed parties.

Workfronts that may form an accepted package

These examples are not automatic inclusions. Final service types, materials, depths, methods, licensed work, testing, connections, approvals and deliverables are defined by the issued requirements and accepted quotation or contract.

Stormwater and drainage civil works

Defined trenching, bedding, stormwater pipework, pits, chambers, culverts, headwalls, backfilling and reinstatement within the accepted civil scope.

Sewer and water civil interfaces

Agreed excavation, pipework support, pits or chambers, crossings and reinstatement where network-owner, design, inspection, testing and connection responsibilities are clearly allocated.

Conduits, pits and service routes

Civil trenching, conduits, ducts, pits and route preparation for electrical or communications services, coordinated with the responsible designer, utility and licensed contractors.

Protection, crossings and reinstatement

Defined service protection, road or pathway crossings, controlled backfill, compaction and surface reinstatement subject to the issued requirements and authority interfaces.

Clear construction, utility and licensed-party boundaries

Underground services delivery depends on complete, coordinated and current information from the responsible project, utility and regulatory parties.

SCE construction role

  • Review the issued civil scope, drawings, specifications, service information, site conditions, access and programme.
  • Define the excavation, trenching, bedding, pipework, conduits, pits, backfill, protection and reinstatement activities included in SCE's accepted scope.
  • Coordinate agreed workfronts, safety and environmental controls, hold points, inspections and construction records.
  • Deliver the accepted civil works and provide the agreed handover inputs.

Appointed, licensed and authority roles

  • Civil, hydraulic, electrical, communications, gas, temporary-works and other specialist design or design changes.
  • Utility locating, isolation, regulated trade work, network connections, specialist testing and commissioning.
  • Engineering acceptance, certification, regulated declarations and registered-practitioner functions.
  • Council, certifier, utility-provider, owner and other authority assessments, consents or approvals.

Information needed for an underground services review

Provide the best available project information so construction fit can be assessed without treating unresolved design, locating, utility, licensed-work, approval or certification matters as complete.

Site and access

Site address, photographs, work area, access, existing surfaces, operating constraints, traffic conditions, work windows and proposed programme.

Issued service information

Current drawings, specifications, service type, route, levels, depths, materials, pits, chambers, crossings and available existing-service records.

Interfaces and responsibilities

Utility-owner requirements, locating, design, isolations, licensed trades, connections, adjoining structures, other services and reinstatement boundaries.

Controls and records

Approvals, environmental and traffic controls, inspections, hold points, testing, commissioning interfaces and required construction or handover records.

Delivery controls and verified credentials

Review the SCE System for the published delivery framework and the certifications and credentials verification page for current evidence. SCE is NSW DBP registered. That registration does not replace project-specific designer, licensed-trade, network-provider, certifier, registered-practitioner or authority responsibilities.

Underground Services FAQs

What underground services packages can SCE review?

SCE can review suitable underground civil utility construction packages involving defined stormwater, sewer, water, conduits, pits, chambers, trenching, crossings, service protection, backfilling, compaction and reinstatement. Final inclusions depend on the issued requirements, utility interfaces, site conditions, access, programme, approvals, safety requirements and accepted scope.

Can SCE review installation of new underground services?

Yes. SCE can review suitable new underground civil service packages where the service type, route, levels, materials, design, utility-owner requirements, licensed-work responsibilities, inspections, testing, connections and reinstatement boundaries are sufficiently defined.

Can SCE review undergrounding of overhead services?

Yes. SCE can review suitable civil workfronts for relocating overhead services underground, including trenching, conduits, pits, crossings, backfilling and reinstatement. Utility design, isolations, regulated trade work, network connections and approvals remain with the responsible authorised parties.

Who is responsible for design, utility approvals and licensed connections?

SCE's principal role is construction delivery and practical coordination for the accepted civil works. Design, service locating, regulated electrical or gas work, network connections, specialist testing, engineering acceptance, certification and authority approvals remain with the appropriately appointed licensed, qualified or authorised parties.

How are existing live services managed before excavation?

Available service information, site conditions, utility requirements and locating responsibilities must be reviewed before excavation. Suitable locating, scanning, non-destructive exposure, isolation, protection and exclusion controls are defined by the responsible parties and the accepted project requirements before the workfront proceeds.

What information should be provided with an underground services enquiry?

Provide the site address, photographs, current drawings and specifications, service type, routes, levels, depths, materials, pits or chambers, existing-service information, utility requirements, access constraints, traffic conditions, target programme, approvals, inspection requirements and reinstatement boundaries.

Where can SCE review underground services projects?

SCE can review suitable underground civil utility construction packages across Sydney and NSW, subject to scope, location, documentation, utility interfaces, access, programme, approvals, safety requirements and commercial fit. Each enquiry is assessed before next steps are confirmed.

Discuss an Underground Services Package

Send the site address, photographs, current drawings and specifications, service type, available existing-service information, access constraints, utility interfaces, programme and known approvals. SCE will review the enquiry for scope, location, documentation, safety, programme and commercial fit before confirming next steps.
