Southbase × assembling — the client always knows what happens next

the win-work frame · why now

In December 2025 the Southbase/Built JV made Health NZ’s national panel for projects over $200m. Panel members compete consortium-against-consortium — and client experience and reporting are scored non-price attributes in Crown procurement. The build wins the job; the client’s view of the build wins the next one.

“No other consortium can show the Crown its project like this.”

the five-beat spine · a fortnight between PCG meetings

Play the fortnight.

A fictional school project — Te Awa Primary, stage 2 rebuild (invented, so no real job is borrowed). The left side is what the site produces. The right side is what the client sees — in their own language, per stakeholder. Switch the lens and watch the same fortnight change register.

Milestone confirmed: block B roof structure complete — with photo evidence from the capture walk, not a sentence in a report.

the smallest question · day 8 one tap

The one thing the contractor needs from the client this fortnight: confirm the site access window for the open day. Nothing else is asked.

Simulated. In the pilot this is the artefact: the month, assembled — dropped straight into the PCG report the client-side PM currently builds by hand.

the tender, tied to the bid · agentically

From the notice to the non-price attribute.

Crown tenders score more than price. When the RFP asks how the consortium will keep the client informed, the answer shouldn’t be written from scratch at 11pm — it should be assembled from the journey you already run. Press the button: the agent drafts the attribute response from this page’s own machinery, and it arrives as a draft, unsigned.

The attribute isn’t written for the bid. It’s running before the bid — and the bid just points at it.

the crew behind the glass · already built

Six agents. One client view.

The client sees one calm pane. Behind it, assembl’s HANGA construction crew — six agents that already exist in the assembl marketplace — each working its own regulated lane and feeding the journey. Wiring them to a Southbase project is the proposed pilot; the agents themselves are built.

Nothing claimed that isn’t built: these six run today as assembl marketplace agents with their remits above. What this concept proposes is the wiring — read-only feeds from what Southbase already runs (Procore-class exports, capture walks) into one signed client view.

the boundary panel · every rule real

What this journey refuses to do.

×Never certifies claims

Payment claims are certified by the QS and the engine of the contract — never by this layer. It reports certification; it does not perform it.

CCA 2002 · the QS’s job

×No consent advice

Consent status is reported from the record. What the council will decide, and how to satisfy a condition, stays with the council and the professionals.

Building Act 2004 · the council’s job

×No sub pricing to the client view

Commercially sensitive subcontractor pricing never crosses into the client pane. The client sees programme truth, not the commercial ledger.

confidentiality · by design

×Nothing sends unsigned

Every client note is drafted by the journey and signed by the PM. The draft is the speed; the signature is the trust.

held for a person

×No programme promises

It reports where the programme is — it never promises the client a date the contractor hasn’t committed to.

one source of truth

ask this concept · live

Ask how it works.

Kia ora — I’m this concept’s own agent. Ask how the client view works, what the crew does, what it refuses, or what a pilot needs.

the regulatory spine · CCA 2002

The Construction Contracts Act 2002 gives payment claims, certification and adjudication their statutory clock — the journey is traceable because the law already makes it so.

Every claim event, decision and consent status on the client view carries its timestamp and its author. The client sees the fortnight; the record satisfies the contract.

One project, one PCG cycle.

One live project, one full PCG cycle, instrumented against the current fortnight of silence. Read-only feeds from what already runs; every client note drafted by the journey and signed by your PM; the proof pack lands in the next PCG report. The numbers you quote afterwards are your own.

What it asks of you: read-only exports from the tools you already run, one owner on your side, and a named PM to sign sends. Nothing installs in week one — and nothing touches the commercial ledger, ever.
