A recorded instruction
An email asks for a revised layout. The reference drawings and the authority for the change need confirming.
EX-01 / CORRESPONDENCEFictional case · Illustrative assumptions
From a disagreement
to a clear next step.
A contractor and employer disagree about additional work. Before choosing a route, bring the evidence, the questions and the commercial assumptions into one view.
01 / Establish what the records say
THE EVIDENCEThe contractor claims £160,000 for changes. The employer queries both the scope and the amount.
A different valuation
The submitted valuation includes extra quantities. Some bill lines may already cover part of the work.
EX-02 / VALUATIONAn incomplete daily record
The diary records work and resources. The link between the change and additional time is not yet established.
EX-03 / SITE DIARYAll records, amounts and references on this page are invented for the demonstration. The example follows the evidence and assumptions approach used in the existing Dispute Adviser Decision Studio.
02 / Separate findings from questions
THE ASSESSMENTA change was discussed.
The example correspondence refers to a different layout. A claimed sum and supporting valuation have been submitted.
Scope, basis and amount.
Check the agreed baseline, the relevant instructions, the valuation method and any overlap with existing work.
Entitlement or outcome.
A document reference or a cost total does not decide liability. The contract, facts and contrary evidence still need professional review.
03 / Make the commercial assumptions visible
A CONDITIONAL COMPARISONThe figures below explore two assumed outcomes. They are not forecasts, fee quotations or recommended routes. Change them to see the arithmetic; no probability or legal conclusion is inferred.
GBP, excluding VAT. Costs already incurred are omitted equally from both forward-looking scenarios. Interest, tax, enforcement, cost recovery, financing and non-cash objectives are excluded. An assumed payment is neither a probable recovery nor a settlement recommendation.
04 / Give the team a useful next step
THE REVIEW OUTPUTFocused information request
Confirm the instruction and its drawing revision. Reconcile the disputed quantities against the original scope. Link resource records to the changed work.
A position that can be revisited
Record what supports the claim, what challenges it and what remains unknown. Update the options after the missing evidence and realistic route budgets have been reviewed.
