Commercial Control Kit.

The toolkit that catches every change, every notice, every entitlement – run by the team you already have.

Change event in. Assessor-ready submission out. Same period.

A governed AI workflow for NEC and JCT change control: the AI drafts every notice, narrative and valuation; your QS reviews, approves and issues each one.

Send us a parked variation · we hand back an assessor-ready narrative, evidence index and entitlement statement — 30 minutes.

The problemIllustrative scenario

Spot a change Tuesday. Plan to log it Wednesday. Never log it. Margin leaks weekly.

14%of variation entitlement lost at the assessor’s desk, per project

Commercial recovery is the most under-systematised value-protection workflow in construction. Change events get spotted but not logged. Notice windows close while the team is busy. Evidence bundles get assembled from email threads at 5pm Friday. Variations get rejected because the cause → effect → entitlement chain isn’t there. Year-end brings a ledger of unclaimed change.

What stays with your team
01

Competent-person judgement and sign-off — a named person from your firm approves every document.

02

Pricing judgement — rates, margins and commercial positions are yours, never generated.

03

Every document carries a named approver from your firm. Nothing is issued unsigned.

04

Your documents stay confidential — processed by the team you deal with, never training data.

02 · The Proof

Judge the output the way an assessor would.

Illustrative · Crestfield Phase 2 is a fictional worked project

CE-009 – the HV switchgear design change from 11kV to 33kV on Crestfield Phase 2 – is a complete, audit-grade worked example: one fictional change event carried from recognition to submitted quotation, with every document the workflow produces on the way. £43,039 and 1.5 weeks, submitted ten days inside the clause 62.3 deadline and still awaiting the Project Manager's assessment. Read the entitlement narrative end to end, or browse the full library.

Scrub the period, D+0 to D+15, and CE-009 climbs the contract gates — logged, noticed, narrated, valued, submitted. It stops there: the quotation went in ten days inside the clause 62.3 deadline and the assessment has not come back. Every sibling event holds its place on the same ledger, each notice inside its window.

Detection → submission

From CE detection to assessor-ready submission pack, same process, same rhythm, every period.

Change control on NEC and JCT contracts – capture, notices, entitlement narratives, evidence, valuation – has become a workflow AI can draft and a QS can govern. The contractors who systematise commercial recovery first will keep the margin everyone else writes off at final account.

A change that lives in an inbox is an anecdote; a change that lives on the ledger is an entitlement.

Built with working QSs and commercial leads who argue entitlement for a living. Pilot results will be published named, or not at all.

05 · Who does what

The AI builds the file.
The QS holds the position.

On a live contract the judgement calls are commercial ones: whether an event is a compensation event, what the entitlement argument is, which rates to defend, when to concede and when to escalate. The kit drafts the notices, narratives, evidence indexes and valuations around those calls. It never makes them – that stays with your QS and commercial manager.

What BuiltAI Does For You
01

Reads and structures contract documents, instructions, correspondence, drawings and programme extracts

02

Classifies change events against the contract, variation, compensation event, instruction

03

Tracks notice requirements (NEC ECC, JCT, bespoke) and surfaces deadlines before they close

04

Drafts variation narratives, cause, effect, entitlement, in the structured form an assessor expects

05

Indexes evidence automatically against change events as documents arrive

What Stays With Your Team
01

Make commercial decisions, that stays with the QS / commercial manager

02

Agree variations, that’s the contract administrator / employer’s agent

03

Issue notices on the contractor’s behalf, a contractually significant act stays human

04

Interpret contract clauses authoritatively, the legal position is the QS’s call

05

Replace contract review by qualified commercial / legal teams

Your documents are processed under your instruction, seen only by the team that works them, never used for model training, and deleted on request.
