Development change-cost assessments

For residential developers

Check a proposed change and its effect on the construction budget for the relevant phase or package.

What is it?

We separate the direct change cost from knock-on package interfaces and distinguish approved costs from forecast exposure. A cost assessment of one proposed or instructed change under one named contract. We agree the original scope, changed scope and records to be assessed.

Additional events, revised scope, contested entitlement, specialist programme analysis and later negotiation are separately scoped.

How does it work?

  1. You explain the work and the decision you need

    You describe the named development phase, plots and contract packages, the result you need and any urgent dates. The introductory conversation checks fit and availability; substantive assessment starts under an accepted instruction.

  2. We agree the scope, responsibilities and fee

    We check suitability, conflicts and capacity, then agree the scope, deliverables and timetable in writing, with a fixed fee or agreed hourly or daily basis. We explain payment terms, VAT and any separate costs before you accept. We identify the contract mechanism, event and stage being priced or assessed, including time-related inputs and the person responsible for notices. We confirm responsibility for urgent actions and specialist input.

  3. You accept the scope and provide the information

    You accept the written scope and provide the operative contract and amendments, original scope, instruction or event notice, changed information, quotation or cost records, quantities and relevant programme evidence. You identify missing items and the versions supplied; we agree who will obtain anything still needed.

  4. We check the records and resolve gaps

    We check the documents against the agreed scope, dates and versions, raise queries and record the basis on which work can proceed. Missing evidence stays identified; we agree any limited assessment or pause affected work until essential information is available. Live deadlines continue to run.

  5. We establish the change and valuation basis

    We compare the original and changed scope, check instruction authority and relevant notices, and identify the applicable valuation rules. We keep entitlement, cost and time questions distinct and refer specialist questions before relying on them.

  6. We assess the contractor’s quotation

    We check the contractor’s quantities, rates, resource allowances and evidence, including omitted work and credits. We identify which costs are supported and which require clarification.

  7. We check time inputs and overlapping recovery

    We coordinate any agreed programme input with the responsible planner, check overlaps with other changes and reconcile the calculation. For NEC work we check the actual form, options, dividing date and quotation procedure; a cost check does not itself determine an extension of time.

  8. You decide on the assessed change

    You review the amount, assumptions and unresolved points. your development decision-maker for the named phase or package authorises the relevant response or submission; formal instructions and assessments are issued only by the person with contractual authority.

  9. We explain the result and complete the handover

    We issue the checked change valuation or assessment and its current approval status, with notices and unresolved time or entitlement actions identified, explain the findings and record unresolved items, next actions, owners and dates. We answer the included clarification and correct our errors. New information, changed scope and later stages need a separate agreement; you decide whether to instruct them.

We confirm timing after checking the scope and available records. Flag any live deadline when you enquire; it continues to run while information is gathered.

Read how we agree the scope, fees and instruction.

What do you get?

You receive the outputs for the stages you choose. Each stage has its own scope, fee and endpoint; later stages are optional.

  • An itemised assessment of the change price, including omissions and the stated valuation basis.
  • A record of supported costs, outstanding queries, assumptions and the change’s current approval status.

Each fixed piece of work includes one consolidated clarification round requested within 10 working days of issue, unless agreed otherwise. New records or scope need a separate agreement; we correct our own errors without charge.
