When you’re building in Western Australia—especially in the Pilbara and the North West—you need a building and construction company that knows the local conditions, understands mine site protocols, and turns up when it says it will. That’s us. Holdfast Contracting Pty Ltd is a proud Wedgefield-based team delivering rock-solid building, plumbing, electrical, refrigeration, and civil works to communities and industries right across WA. From modular building installations to leak detection on remote sites, we provide end-to-end solutions that keep projects on schedule and are built to last.
We wrote this guide to demonstrate how our integrated services operate in the real world—how we plan, coordinate, and deliver solutions for mining, industrial, commercial, defence, and residential clients. You’ll also see why our reputation for mine site refurbishments, plumbing solutions, concrete formwork, and civil construction continues to grow across the state.
We started Holdfast Contracting Pty Ltd to deliver quality workmanship with a friendly, local touch. Operating out of Wedgefield, WA, we’ve built deep roots in the regions—working on mine sites, civil infrastructure, modular facilities, and industrial maintenance from the Pilbara to the Mid West and beyond. We’re not a fly-in, fly-out outfit; we’re WA locals who understand the distances, the weather, and the need to get things right the first time.
Our clients stick with us because we make their lives easier:
Holdfast Contracting Pty Ltd delivers a complete service stack so you don’t have to juggle multiple contractors. Our crew coordinates plumbing, electrical, refrigeration, carpentry, concrete and formwork, and civil works under one roof—streamlining approvals, sequencing trades, and accelerating handover.
Major capability areas include:
When it comes to plumbing solutions and civil works in WA, speed and accuracy are everything. We maintain and install water systems for remote communities and mine operations, run CCTV drain inspections, and perform jetting and leak detection that pinpoint issues before they snowball.
In regional WA, a minor concealed leak can become a major cost and a production headache. Our team uses non-invasive leak detection tools and high-resolution CCTV to locate defects in pipework quickly. We then jet and clear the line to restore flow and prevent repeat failures.
We install and service Water Treatment Plants (WTPs) and Wastewater Treatment Plants (WWTPs) designed for remote operations. From specification to commissioning and scheduled maintenance, we keep systems efficient and environmentally compliant.
From trenching and backfilling to site drainage, culverts, pits, and concrete hardstands, our civil construction crews build durable assets that withstand heat, traffic, and heavy equipment. We also coordinate service corridors (water, power, comms) for modular camps and facilities, keeping layouts tidy and future-proof.
You can’t hand over a facility without power that’s safe, compliant, and reliable—especially in remote WA. Our licensed electricians and refrigeration technicians deliver light and power installations, fault finding, air conditioning installations, and breakdown response that get sites back online quickly.
What clients get: faster approvals, safer energisation, and cooler, more comfortable facilities for crews in harsh climates.
Strong structures begin with concrete and formwork done right. Our team delivers slabs, footings, retaining walls, industrial platforms, and stair/landing solutions with millimetre accuracy. On the carpentry front, we handle:
We manage the lot—from ground prep and reinforcement to pour, cure, and polish—so the final finish is something you’ll be proud to sign off.
Modular buildings make sense in WA: they’re fast to deploy, easy to move, and built for harsh environments. We provide full modular installation, transport coordination, and complexing services, delivering a turnkey building installation with minimal disruption.
Whether it’s a new mine camp, a remote office, or community infrastructure, we make modular simple and safe.
If your facilities are showing their age—or you’ve reactivated a site—our mine site refurbishment crews can overhaul kitchens, ablutions, offices, crib rooms, and amenities to current standards. We work live or staged, depending on the site’s operational constraints.
The reason many clients pick Holdfast is simple: we coordinate everything. You get one point of contact, tighter cost control, and shorter timelines. Our integrated model keeps trades in sequence, avoids clashes, and ensures buildability from day one.
The result is a smoother project, fewer variations, and a facility that performs from day one.
Every Holdfast crew member is:
We know how to work safely in heat, dust, cyclone zones, and remote conditions. That’s why our clients trust us with critical assets and tight schedules.
