Pipeline installation

Pipeline delivery planned around the site.

PRCD leads pipeline construction from methodology and mobilisation through installation, testing and handover. HDPE and poly pipeline work is self-performed, with qualified specialists controlled by PRCD where the scope requires them.

Discuss a pipeline scope Review the scope

Package options: Construct-only, supply and installation, or installation-only
Primary material: HDPE and poly systems
Operating area: Central Queensland and Queensland-wide projects

Delivery model

Clear responsibility from the first site walk.

PRCD controls the pipeline package, the supporting civil work and the delivery records. The contracting model is set to suit the scope without blurring technical responsibility.

Self-performed

HDPE and poly pipeline preparation, joining, installation and associated site work are positioned as PRCD-delivered activities.

Controlled specialists

Steel welding, fabrication and other specialist work is completed by suitably qualified subcontractors selected and managed under PRCD controls.

Design boundary

PRCD can contribute constructability, sequencing and site knowledge. Formal design and primary design liability remain with the appointed qualified designer or engineer.

Pipeline scope

Construction, crossings and connection work.

The final work method and record set are matched to the pipeline system, operating environment and client requirements.

Route preparation

Clearing, survey, set-out, access and work-front preparation.

Trenching and earthworks

Excavation, bedding, dewatering, backfill, compaction and reinstatement.

Poly welding and joining

HDPE pipe preparation, butt fusion, electrofusion and controlled jointing activities.

Mechanical installation

Valves, fittings, flanges, flow-control items and associated infrastructure.

Crossings and interfaces

Road, rail, watercourse and service crossings coordinated with the supporting civil scope.

Pump and pipeline infrastructure

Pump stations, tie-ins and project-specific supporting systems.

Testing and commissioning

Pressure testing, inspection records, quality documentation and commissioning support.

Operating-site work

Repairs, replacement, temporary works, emergency response and brownfield modifications.

Applications and environments

Systems used across mine, industrial and utility sites.

PRCD assesses the material, service, site condition and licensing requirements before confirming the delivery approach.

Before mobilisation

A proposal built around the actual work front.

PRCD can start from a supplied tender or job package. A site inspection is strongly recommended so the proposal and methodology reflect access, interfaces, operating constraints, temporary works and client requirements.

01
Review the package
Confirm scope, drawings, specifications, programme and client deliverables.
02
Inspect the site
Test the documents against access, ground conditions, services, interfaces and operating requirements.
03
Set the work method
Define sequencing, people, plant, suppliers, subcontractors, controls and required records.
04
Prepare the proposal
Submit a package-specific delivery approach with responsibilities and assumptions made clear.

Inspection and handover

Records built as the pipeline is installed.

Inspection and test plans, weld reporting, pressure testing, quality records, commissioning information and handover requirements are established for the package. The exact dossier is agreed against the client specification and the work performed.

Bowen Basin mine-water programme

Proven pipeline delivery

From major pipeline package to multi-scope mine infrastructure programme.

PRCD's delivery leadership has managed and supervised major mine-water pipeline work at Tier 1 Bowen Basin operations. The scope has covered HDPE installation, supporting civil construction, buried road and watercourse crossings, valves, flow-control infrastructure, testing and commissioning.

As site requirements changed, the original package grew into additional pipelines, rehabilitation irrigation, fill-point and dredging-pump infrastructure, relocations, bulk civil work, test pits, grubbing and clearing. A major DN315 pipeline relocation was delivered on time and on budget.
