Commercial construction, priced by the people who build it.
New build, design and construct, fitout, refurbishment and end-of-lease make-good, to $20 million under a single contract. Trade packages go to the open market rather than to a closed panel, so every rate in your price was competed for.

Four ways in.
Every one of these is delivered by the same team, under the same contract discipline.
Commercial Construction
Office, education, health, hospitality and retail. New builds, design and construct, fitout, refurbishment and end-of-lease make-good, under one contract.
Industrial Construction
Warehouse, distribution and services-heavy facilities. We build the enclosure around the operation that has to run inside it, and we start from the operation, not from the building.
Delivery Models
Turnkey design and construct, with no client-side manager required. Four ways to buy a building, and what each one leaves on your side of the table.
Client-Side Project Management
Representing the client, not the builder. Project manager, superintendent or contract administrator on somebody else’s build. On any one project we do this or we build, never both.
Residential Construction
Houses up to two storeys, in South Australia and Victoria. Licensed and registered in the company name, and administered the way a commercial contract is.
What you are issued at each stage, and when.
Three words on a logo are worth nothing unless each one names something that actually happens. Ours name the three stages of a construction project.
Plan
Feasibility, cost plan and buildability review.
Feasibility, cost plan and buildability review, before there is a documented set to price. The cheapest work on any project and the most often skipped, and the one we are most often engaged for on its own.
Build
Open-market trade packages, reported in writing.
Trade packages advertised to the open market rather than issued to a closed panel, so every rate in your price was competed for. One monthly report, weekly site minutes, and a variation priced and issued to you before it is built.
Advance
Practical completion and an indexed handover.
Practical completion, defects managed to expiry, and a handover the asset keeps: as-builts, warranties, manuals and commissioning results, indexed. The building can be run and extended from the file without calling us.
Our core values.
SOLID.
Safety
Written safety plans in use on every project, with hazard controls documented before work starts.
Ownership
Full accountability and pride in every task and outcome.
Loyalty
Transparent, respectful relationships built on trust.
Integrity
Ethical conduct putting client interests first.
Delivery
Committed to delivering quality on time and on budget.

Eight sectors we take work in.
The shell is rarely the hard part. Government, data centre and defence are sectors we are building towards: we have not delivered in them, and we say so in those words in any submission.
A referee conversation tells you more than a case study ever will.
If you want to speak to a client we have worked for, ask. Referees are provided on request at shortlisting, with the client’s consent.

Founder’s project contributions
The director brings 15+ years of construction experience. Projects from that record are the founder’s prior-firm contributions rather than JCGAU work. We are careful about the difference and we will always tell you which is which.

Frequently asked questions.
The answers below are the ones we give on the phone. Each is something you can check against a public register, a named client or a document we will send you.
What size projects does JCGAU take on?
Up to $20 million under a single contract, in commercial and industrial new build, fitout, refurbishment and end-of-lease make-good. If an opportunity sits above that line we will tell you plainly rather than price it and find out later.
We want a turnkey outcome. What do you recommend?
Design and construct, and a feasibility study before it. The feasibility settles the site, the constraints and the order of cost while a decision is still cheap to change, and we work with you through it to build the design brief rather than wait for one to arrive.
The design and construct contract then follows: one contract, one point of accountability, and the design and the price moving together instead of being reconciled against each other later. You take back a finished, commissioned building, with the as-builts, warranties, manuals and commissioning results indexed at handover. It is how the Intertek Sydney laboratory is being delivered. Delivery models sets out the alternatives, including early contractor involvement and construct only.
Do you have people in the state my project is in?
Yes. Site management is local and permanent in the state the project is in, and the head office is in South Australia. We are licensed in South Australia, registered in Victoria, and we build Class 5, 6, 7 and 8 in New South Wales. We do not run a project by visiting it.
Our landlord has to approve us before anyone starts. What do you send them?
One pack, sent by us to the building manager rather than handed to you to forward. Certificates of currency naming the owner and the managing agent, a safe work method statement for each high risk activity, our quality and WHSE management plan, and the BuildPass record for every person who will come through the dock, subcontractors included.
With it go the permit applications the building runs: hot works, penetrations, fire detection isolation, riser and roof access, and after-hours works. The programme goes with it marked to show which works sit inside the noise window and which sit outside it. We work to the building’s rules rather than ask for exceptions to them.
Can you build in a building that stays open and trading?
Yes, and it is a large part of what we do. In an occupied building the dock, the lift booking, the noise window and the after-hours access govern the programme, so they are priced and sequenced at tender rather than discovered on site. Fitout and refurbishment sets out how that is handled.
What does an end-of-lease make-good involve?
Returning the tenancy to the condition the lease requires, by the date the lease requires it. In practice that is strip-out of the fitout, removal of the services installed for the tenant, reinstatement of ceilings, lighting, floor coverings and wall finishes where the clause calls for it, making good the base building fabric, and the photographs, certificates and commissioning records the agent asks for at handover.
The scope is set by the make-good clause and the condition report rather than by the building, so we read both before we price. We take make-good work in all three states.
What is client-side project management?
Where the project manager is appointed by you and reports to you, while somebody else builds. We can be appointed as project manager, superintendent or contract administrator on projects in all three states. On that project we will not tender for the building work, and we will not take a margin, a rebate or a supplier commission on it. Client-side project management sets out the appointment.
Will you act as our project manager as well as build the work?
No. We do one or the other on a project, never both. Where we act for you we can be appointed as project manager, superintendent or contract administrator, and the separation is a term of the appointment rather than a matter of good faith. Client-side project management explains the appointment.
Are your management systems certified?
No. The plans are written to the requirements of ISO 9001, ISO 45001 and ISO 14001, they are in use on live projects, and they are not certified yet. We will not imply otherwise, and if we take certification we will publish the certificate number and its scope, and not before. We send the plan, the project WHS management plan and the environmental controls for a live opportunity so your team can assess them directly.
How do you procure trade packages?
Packages are advertised to the open market through EstimateOne rather than issued to a closed panel. It takes longer and it means every rate in your price was competed for. Site access, induction, competency and licence currency are then managed through BuildPass before anyone starts.
Can we speak to a referee before we appoint you?
Yes. Referees are provided on request at shortlisting, with the client’s consent. The director brings 15+ years of construction experience, and projects from that record are the founder’s prior-firm contributions rather than JCGAU work. We are careful about the difference and we will always tell you which is which.
Send the site address and whatever drawings exist.
Incomplete is fine. The address alone tells us the zone, the authority, the building and usually the constraints. Acknowledged the same business day, and a scoping call or a considered answer within two.
