Your project files in. Priced BOQs, notices & programmes out.
Orpheus drafts the deliverables you actually issue — grounded in your project's own documents, not the open internet. AS 2124 / AS 4000 aware, Australian rates built in.
Built by estimators and engineers, not a generic AI lab. Orpheus comes from Synthetik — a Cenex company — the Australian estimating & engineering team pricing live civil infrastructure across QLD and NSW. The mocks on this page use the language and standards we work in every day.
Find your job on the tools.
Orpheus speaks the language of the people who deliver Australian projects — and does the work they'd otherwise do by hand.
Estimators
First-principles build-ups and priced BOQs from the tender library — in your rates, your region, your base date.
Contract Administrators
Variations, EOTs and payment claims drafted with the right clause references and evidence already linked.
Planners & Schedulers
Read the baseline .xer, test recovery options against the critical path, and export straight back to P6.
Project & Delivery Engineers
ITPs, lot reviews and conformance evidence against the spec — plus the day-to-day writing the job runs on.
A real project workspace, not a blank chat.
Files are indexed once, then reused across cost, commercial, programme, QA and day-to-day project work — the same context, everywhere.
"Isn't this just ChatGPT with a hard hat?"
Fair question. The difference isn't the model — it's that Orpheus works inside your project, in Australian standards, and hands back files you can issue.
Built for the conversations construction teams actually have.
The same project files stay attached as the mode changes from cost to contract, programme, QA or general project work.
Cost
Rates, BOQs, build-ups, estimate strategy, and Australian cost reasoning.
Contracts & Commercial
Clauses, claims, procurement, payment, EOTs, and practical contract support.
Construction Programming
Sequencing, lookaheads, possessions, milestones, delays, and planning logic.
QA
ITPs, lot reviews, conformance evidence, NCRs, and specification workflows.
General
Writing, planning, summaries, research, and day-to-day project support.
One context, every mode
Switch modes without re-explaining the project. Your files, rates and programme come with you.
The heavier workflows live beside the chat.
Orpheus is the front door, but the workspace also carries takeoff, estimating, commercial, programme, cost data, files and templates.
Build estimates from BOQ input and project context.
Combine BOQ line items with location, base date, estimate class, procurement model, on-costs, labour, material and plant assumptions.
Produces first-principles build-ups with export-ready totalsTurn contract events into structured notices and claims.
Prepare variations, EOTs, latent condition notices, payment claims, delay analysis and contract reviews with linked takeoff or estimate context.
Generates notice packages, schedules and QA summariesReview recovery paths and programme exports.
Preview critical-path movement, milestones, float impact and recovery options in a construction programme view.
Exports XLSX, PDF and Primavera P6 XER packagesSearch and manage Australian rate libraries.
Filter rates by library, category, tags, date and region, then use the cost database as the estimating reference layer that stays reusable across projects.
Keeps reusable rates available for future projectsHigh-stakes work needs answers you can check.
A mis-cited clause can time-bar a claim. Orpheus is built to draft for a professional to review — with your data kept yours, and every reference traceable to the document it came from.
Your data stays yours
Your files, rates and notices are never used to train AI models, and are deleted on request. Australian data residency for teams that need it on public work.
Every reference is traceable
Clause citations, rate sources and programme logic link back to your indexed documents — so your CA or estimator verifies before anything is issued.
Isolated workspaces
Per-company tenancy. Your rates and tender pricing never touch another contractor's workspace — even when you're both chasing the same job.
