The RGS Approach

The workshop and the worksite.
Connected from day one.

RGS Engineering is a Western Australian pipe fabrication and shutdown contractor supporting water, mining and industrial projects.

We fabricate process, utility and MSCL pipework in our Perth workshop, then install, tie in and test it in the field. Keeping fabrication and installation together gives the project one accountable team and a clearer line from drawing to handover.

01

One accountable contractor

Workshop and site delivery managed together.

02

Built around the outage

Pre-fabrication and practical sequencing to make site time count.

03

Evidence with the work

Traceability, inspection records and handover documentation compiled as the job progresses.

Capabilities

Fabrication in the shop. Execution on site.

From individual spools and specialist fittings to shutdown packages, installation, maintenance and skilled labour supply.

Shutdowns & turnarounds

Planned to the hour. Not the day.

A shutdown is a fixed window with a queue of people waiting on the other side. We scope joint by joint, pre-fabricate everything the drawings allow, and turn up with the spools, the consumables and a briefed crew.

How we work

Three of the six things we will not trade away.

SAFETY

Everyone goes home

Live plant, hot work and confined spaces do not forgive shortcuts. The permit, the isolation and the plan come before the first cut, every time, regardless of who is waiting.

EVIDENCE

Show the record

A weld is only as good as what you can prove about it. Heat numbers, weld maps, NDT reports and test packs are compiled as the job runs, not reconstructed at handover.

CANDOUR

Say it early

If a scope will not fit the window or material will not land in time, you hear it while there is still room to act. Bad news does not improve with age.

Send us the scope. We will tell you what fits the window.

Who we are

The workshop and the worksite.
Connected from day one.

RGS Engineering is a Western Australian pipe fabrication and shutdown contractor supporting water, mining and industrial projects.

The business

Built around one awkward truth.

Piping work goes wrong at the joins — between the shop and the site, between the fabricator and the installer, between the drawing and what is actually in the ground. Most of a project's arguments happen at those seams.

RGS Engineering exists to remove them. We fabricate and we install, so there is a single party answerable for whether the spool fits. That is a commercial risk we take on deliberately, because it is cheaper to solve at the drawing stage than at 2am in an outage.

We work to ASME B31.3, AS 4041 and AS/NZS 1554, with qualified procedures, coded welders and a documented ITP behind every package handed over.

Company values

Six things we will not trade away.

Values are only worth writing down if they cost something to hold. These each rule out work we could otherwise take, or profit we could otherwise book.

SAFETY

CANDOUR

Say it early

If a scope will not fit the window or material will not land in time, you hear it while there is still room to act. Bad news does not improve with age.

CRAFT

Fit-up is the job

Anyone can lay a bead. Getting alignment, gap and purge right so the joint passes first time is the difference between a shift and a re-work.

OWNERSHIP

One accountable party

We fabricate it and we install it. When something does not line up there is nobody to point at, which tends to concentrate the mind at the drawing stage.

RESPECT

For the client's plant

It is somebody's asset and somebody's production. We leave the area clean, the punch list closed and the paperwork complete.

What that means in practice

Four commitments you can hold us to.

01

One accountable party

Shop and site under one contract. If the spool does not fit, it is ours to fix, and we absorb the cost of finding out why.

02

Documentation at handover

Weld maps, NDT reports, test packs and marked-up as-builts complete when the asset goes back, not chased for six weeks afterwards.

03

Early warning

Schedule and material risks are raised as soon as we see them, in writing, while there is still time to change the plan.

04

Clean hand-back

Punch list closed, area cleaned, scaffold and equipment demobilised. Your operators get the plant back in the state they would want it.

Send us the scope. We will tell you what fits the window.

Shutdowns Site · SHD
Shutdowns

Shutdown work planned to the hour.

A shutdown is a fixed window with a queue of people waiting on the other side of it. We scope the work joint by joint, pre-fabricate everything the drawings allow, and arrive with spools, consumables and a crew already briefed.

Nights, weekends and out-of-hours windows are normal rather than exceptional. On live water and process assets the outage window governs everything else, so the plan is built backwards from it.

  • Scope & planningJoint-level scoping, resource histograms, hour-by-hour plans.
  • Pre-fabricationSpools built and tested ahead so site work is fit-up and closure only.
  • Tie-insHot and cold tie-ins into live systems under permit and isolation.
  • Out-of-hours crewsNight shift and weekend crews to protect supply and production.
  • Rapid responseBreakdown and emergency repair crews mobilised at short notice.
  • Hand-back packAs-builts, test packs and punch list closed before demobilisation.

Installation Site · INS
Installation

From the shop floor to in service.

Installation crews that pick up where the workshop leaves off — setting out, rigging, aligning and bolting up spools, then testing and commissioning the system.

The team that fabricated the spool is usually the team that installs it, which is where fit-up problems get solved instead of argued about.

  • Set-out & surveyLines and levels established before the first spool is lifted.
  • Rigging & placementCrane and telehandler work under lift studies and permits.

Keeping installed assets running.

Routine and reactive maintenance on installed pipework — leak repairs, section replacements, corrosion cut-outs, flange and gasket work, and support renewal.

Where an asset keeps failing in the same place we would rather fix the cause than keep selling the repair. Inspection findings come back with a recommendation, not just a photograph.

Shutdowns & turnarounds

Planned to the hour. Not the day.

Scoped joint by joint, pre-fabricated off site, and executed by crews who arrive briefed.

The constraint

The window governs everything else.

On a water asset an overrun lands on end users. On a process plant it lands on production. Either way the outage window is a promise somebody else has already made, and every decision in a shutdown plan is downstream of it.

So we plan backwards from the hand-back time. What has to be welded in position, and what can be pre-fabricated? Where are the isolations, and how long do they take to prove? Which tasks genuinely cannot start until another finishes, and which have just always been done in that order?

Out-of-hours work is standard, not a premium extra. Nights, weekends and staged windows are how most of this work gets done without interrupting supply.

Process plant during a shutdown
Fig. 01Live plant, outage window
Sequence

Four phases. One window.

These run in order, and each one depends on the last being finished properly. That is the whole method.

01

Scope

Walk the plant, mark up the isometrics and scope the work joint by joint. Every task gets a duration, a crew size and a predecessor — which is what turns a wish list into a plan you can commit to.

02

Pre-fabricate

Everything that can be built before the window is built before the window. Spools are welded, tested and tagged in the shop, so site work reduces to fit-up and closure welds.

03

Execute

Crews arrive briefed, permits raised and isolations confirmed. Progress is tracked against the hour-by-hour plan and variances are escalated in the shift they appear, not at the end.

04

Hand back

Test packs signed, punch list closed, as-builts marked up and the area cleaned before demobilisation. The asset goes back complete rather than conditionally.

Also available

Outside the planned window.

RSP

Breakdown response

Crews mobilised at short notice for failures that will not wait for the next planned outage, including after hours.

TIE

Live tie-ins

Hot and cold tie-ins into operating systems under permit and isolation control, with the sequence agreed in advance.

PRE

Pre-shutdown fabrication

Spools built and tested in the months before the window so site scope is reduced to the joints that must be welded in place.

Send us the scope. We will tell you what fits the window.

Sectors

Where our pipework ends up.

Water is the anchor market. The fabrication and welding disciplines transfer directly to every sector that runs fluid through steel.

01

Water Infrastructure

Bore and raw water pipelines, pump and valve stations, water and waste water treatment plants, dosing stations and RO facilities. MSCL and stainless pipework for utilities, treatment technology vendors and their head contractors.

02

Mining & Minerals

Process and services piping, borefield and dewatering infrastructure, pump stations, tanks and hoppers, pipe supports and structural steel, plus shutdown crews for planned outages on fixed plant.

03

Oil & Gas

Process piping, pipeline facilities, compressor and metering station pipework, skids and modules, in greenfield construction and operating brownfield environments alike.

04

Power & Utilities

High pressure steam and utility piping, fuel and gas distribution, tanks and vessels, and shutdown support on generation and network assets.

05

Industrial & Petrochemical

Process piping, exotic material fabrication, debottlenecking works, chemical storage and containment, and maintenance on operating plant.

06

Transport & Government

Buried water and gas service diversions and relocations, utility works around road and rail projects, and public works packages for state agencies and their contractors.

Water infrastructure

Critical service, unforgiving windows.

Water supply does not get to pause while pipework is replaced. Bore and raw water systems, pump and valve stations, treatment plants and RO facilities all carry the same constraint: the interruption to end users has to be minimal and predictable.

That is why MSCL fabrication and out-of-hours shutdown work sit at the centre of what we do rather than at the edges.

Quality & HSE

Qualified. Inspected. Documented.

The codes the work is executed against, the controls that make live plant work survivable, and the record you receive at the end.

Safety

Live plant. Hot work. Confined spaces.

Most of our work happens on somebody else's operating asset, often at night, often inside a permit. The controls are not paperwork — they are the reason the job is survivable.

S01

Permit and isolation

No cut, no weld and no break of containment without the permit, the isolation and the verification in place. On live systems this is the control everything else depends on.

S02

Planned before mobilisation

JSAs, lift studies and confined space plans written and reviewed before the crew leaves the yard, not filled in at the gate.

S03

Fatigue management

Shutdown work runs out of hours. Rosters are built with fatigue in mind, because a tired welder on a night shift tie-in is a risk to more than the weld.

S04

Reporting and improvement

Every near-miss and hazard reported and investigated, with findings written back into the procedures rather than filed.

Handover

What you receive at the end.

The manufacturing data record is assembled as the job runs. It is complete when the asset goes back, not six weeks later.

MDR

Weld map & welder register

Every joint numbered, with the welder ID and the qualified procedure used.

MDR

Material certificates

Heat numbers traced from incoming material through to the finished spool.

MDR

NDT reports

RT, UT, MPI and PT results reported against the inspection and test plan.

MDR

Test packs & as-builts
