Origin Story
Why QCG Exists Built to close the gap between hands-on construction and professional project delivery.
I started QCG after 15+ years working across civil infrastructure, Defence, government and remote projects. The same delivery problems appeared repeatedly: contractors who could perform the physical work but struggled with planning, documentation, programme, commercial management and accountability.
QCG was built to bridge that gap: a practical construction contractor with engineering and project-management capability built into the delivery team. We aim to understand the scope properly, plan the work before mobilisation, communicate issues early and hand over the documentation without being chased.
“Director-led. Infrastructure-experienced. Built for accountable delivery.”

How We Work
Our Values in Practice These aren't posters on a wall. They're how we run every job.
Engineered Thinking
We review methodology, access, sequencing, temporary works, interfaces and hold points before mobilisation. Buildability is considered before it becomes a site problem.
Programme Discipline
We plan realistic sequences and communicate changes early. If something threatens the programme, the client hears it from us before it becomes a downstream surprise.
Director Accountability
Clear ownership, short decision paths and direct communication. The people responsible for the outcome are accessible throughout delivery.
Price to Deliver
We document inclusions, exclusions and assumptions and price the methodology we expect to build. A tender number is only useful if the project can actually be delivered for it.
Safety First, Every Time
Every site has a pre-start. Every high-risk activity has a SWMS. Safety isn’t a box we tick for the head contractor. It’s the first conversation we have on every job, every time.
Built for the Next Job
We’re not interested in a quick win. If we can’t deliver what you need, we’ll tell you before we start. The contractors who keep calling us back do so because we treated the first job like it mattered.
The QCG Process Straightforward from first conversation to final sign-off.
STEP 1
First call and project review
You describe the project, we ask the right questions. Scope, site, programme, constraints. If it’s not the right fit, we’ll say so before you waste any time.
STEP 2
Scoping and risk review
Before we price anything, we work through the detail. Site access, reinforcement requirements, programme interfaces, drainage, levels, exclusions. We’d rather find the issues here than on pour day.
STEP 3
Your quote
Inclusions, exclusions, and assumptions written out clearly. No fine print. No surprises when the invoice arrives.
STEP 4
Pre-mobilisation
Programme locked in before we set foot on site. SWMS prepared, materials procured, inspections planned. Pour dates confirmed in advance, and you hear from us early if conditions require a change.
STEP 5
On site
Pre-starts every morning. Reinforcement inspected before every pour. Direct communication throughout, not updates filtered through someone who wasn’t there.
STEP 6
Handover
QA documentation complete and ready. ITP sign-offs, pour records, compliance confirmation. Everything you’d expect to hand back to a superintendent, without having to chase it.
