Five steps.
From spec to site.
Every Onyx Supply Co engagement runs the same disciplined sequence — specification review, value engineering, direct procurement, compliance alignment, and program-integrated delivery. The output is procurement that lands on price, on quality, and on program.
Step
Specification Review
Specification Review
Where the cost lives.
We analyse project drawings, BOQs, and finishes schedules to identify cost-saving opportunities. The output is a clear map of where structural cost reduction is available — by category, by line item, by package — without compromising design intent.
Step
Value Engineering
Value Engineering
Specification redesigned to brief.
We redesign specifications to maintain design intent while optimising cost and constructability. Material selection, fabrication method, hardware schedule, and finish detail all reviewed against the lowest-cost path to function.
Step
Direct Procurement
Direct Procurement
Manufacturer relationships, factory QA.
We source directly from vetted international manufacturers with strict QA controls. Factory-stage inspection — physically present, measuring against specification, with rejection authority before container load-out — keeps quality at source.
Step
Compliance Alignment
Compliance Alignment
AU standards, certified at source.
We ensure products meet relevant Australian standards, certification, and project requirements — NCC 2025, AS/NZS series, electrical and plumbing approvals, fire and acoustic ratings, category certifications. Cleared at the manufacturing stage, not at the wharf.
Step
Delivery Integration
Delivery Integration
On site, on program.
We coordinate logistics, staging, and delivery aligned with your construction program. Sequenced unloading, floor-by-floor fit-out coordination, staged container schedules — the package lands when the program needs it, not before and not after.
Concrete
timelines.
Procurement is a calendar problem before it's a cost problem. These are the intervals we work to — measured against production reality, not best-case conditions.
Brief to procurement plan
From the moment we receive drawings, BOQ, or finishes schedule to a value-engineered procurement plan with line-by-line cost-opportunity analysis.
Procurement plan to order
Specification finalisation, manufacturer selection, contract terms, and forward-pricing locked in across the package.
Order to site delivery
Production, factory-stage QA inspection, compliance certification at source, and program-integrated delivery scheduling. Scope-dependent — large packages or complex logistics may extend.
Volume program lock-in
For multi-development programs, master-spec procurement contracts run on 24-month forward pricing with controlled-variation flexibility.
The first week is on us. Step 01 — specification review and cost-opportunity analysis — runs without commercial commitment. You see the saving before you sign.
Procurement that
lands on program.
Five steps run end-to-end produce a procurement function that meets the project on three axes simultaneously — price, quality, and program. The cost saving is structural, not promotional. The compliance is documented, not assumed. The delivery is sequenced, not best-effort.
