Specialist WHS tender support for construction, civil and demolition contractors across Western Australia. From tender response writing and WHS management plans to SWMS packs, prequalification submissions and post-award mobilisation — we handle the WHS evaluation criteria so you can focus on winning the work.
A losing tender response is rarely about price. It's about whether the WHS evaluator can see, in your document, that you'll actually run a safe project. Evaluators are scoring against weighted WHS criteria — competence, documented systems, project-specific risk thinking, regulatory understanding, past performance evidence.
Most small-to-medium contractors lose marks because they recycle generic WHS content from previous bids, paste in template policies that don't match the project's actual scope, or skip evidence requirements entirely — figuring "they'll work it out from the price." Evaluators don't. They score what's written.
Every Winchester tender engagement is built around the specific evaluation criteria of the tender — not a generic WHS write-up. We read the tender documents, map the WHS criteria, write directly to them, and back every claim with the evidence the evaluator is looking for.
Chasing subcontractor work and need to be tender-eligible. We package the basic WHS plan, SWMS for your actual scope, RPE/PPE program, and the evidence that puts you in front of selective subcontractor lists. Often the difference between getting on the panel and not.
Bidding for mid-tier government work and major-builder subcontracts — but the WHS system isn't fully built out yet. We develop the full WHS framework (policies, procedures, registers, training matrix) and write the tender response itself, so your business is tender-eligible from the inside out.
Have WHS systems and tender experience, but need senior-level help writing the response itself — addressing the actual evaluation criteria, sharpening the language, integrating ISO 45001 alignment statements and packaging evidence. Most engagements turn around in 5–10 business days.
Need to get listed on Rio Tinto OASIS, BHP, Fortescue, Avetta, Cm3, ISNetworld, Achilles or ConsenSys — and renew them annually. We've done this many times. We'll have you submitted, approved and visible to the buyer.
We read the tender, map the WHS evaluation criteria, and write the response directly to each weighted question. Every claim backed with evidence. Clean, evaluator-ready language — no fluff, no padding.
A WHS Management Plan written for the specific project being tendered — scope-mapped, site-mapped, with controls drawn from the actual hazards on the works. Not a recycled template — built fresh for the bid.
A task-specific SWMS pack covering each high-risk construction work activity in the scope — properly written, properly controlled, properly aligned to the WHS regulations. Usually 5–15 SWMS per package.
For businesses without a complete WHS framework yet. Policies, procedures, registers, training matrix, document control — everything tender-evaluators look for in the underlying system, built from scratch.
You've drafted the response yourself — we review it before submission. Spot the weak answers, identify missing evidence, sharpen the language, and catch the gaps a tired in-house team won't see at midnight on submission day.
You won the tender — now make good on the commitments. On-site WHS support during mobilisation, document rollout, toolbox delivery, supervisor coaching, and audit-ready close-out.

WHS plans, SWMS, registers, evidence — built or refreshed for the bid.

Major-project owners and Tier 1 builders don't just take your word for it. They want you on their nominated prequalification platforms — verified, scored, and audit-ready. We've done all of the major systems across construction, civil, demolition and mining sectors in WA.
Initial submission is one project. Annual renewal is another. Responding to clarifications is yet another. We handle all three — submission, annual update, and the dreaded "we need this clarified by Friday" email — so your prequalification stays current and you stay visible to the buyer.
Every platform has its own quirks: OASIS wants this, Avetta wants that, Cm3 wants something different again. We know each one. Engagements are typically $1,800–$4,000 per platform, depending on the scope and whether we're submitting from scratch or renewing.
