# Development remedial-cost assessment

For residential developers

Assess the supported cost of correcting the identified defects in a development phase or package.

## What is it?

We distinguish defects in the original work from upgrades and prevent the same repair appearing in several package claims. Support with the costs claimed for defects or damage. Choose an assessment, preparation of the agreed claim or response, or one defined response round. Each stage has a separate fee and endpoint; you only commission the work you need.

Diagnosis, design responsibility, causation and liability opinions are separate. This does not duplicate an existing contra-charge cost review.

## 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 agree the items, evidence cut-off and assessment, preparation or response stage you need. We identify the development contract, phase or package and separate its disputed costs from other project accounts. Legal advice, representation and specialist analysis are separately appointed. 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 contract, defect or damage list, photographs and event records, supplied technical findings, agreed repair options, quotations and cost 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 basis and chronology
    
    We establish the instructed commercial question and the technical findings we can rely on. The appointed technical adviser determines cause, compliance and necessary repair scope; we identify unanswered questions before costing dependent work.
    
6.  ### We assess the supported repair costs
    
    We compare supported repair options and quotations, checking quantities, rates, access and associated costs. We separate necessary repairs from improvements or unrelated work and account for mitigation, credits and overlapping amounts.
    
7.  ### We check the findings and explain the options
    
    We check calculations, source references and consistency between the evidence, assumptions and proposed position. We issue the assessment findings before your next-stage decision, identifying weaknesses, missing evidence and proportionate actions, including any specialist work needed.
    
8.  ### You decide whether to proceed
    
    You review the repair-cost findings and resolve technical questions with your adviser or builder. You decide whether to obtain further quotations, pursue a claim or instruct a separate response; we do not assume the next stage is included.
    
9.  ### We explain the result and complete the handover
    
    We issue the itemised remedial-cost assessment or response, with technical assumptions and supporting cost references, 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.
    

**Timing:** the action timetable is agreed against the actual deadlines and available records. We aim to respond to enquiries within one working day; substantive work starts only after capacity and instructions are confirmed. Working days start when the agreed scope and required information are available.

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.

## 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.

-   A phase or package remedial-cost schedule supported by the supplied technical findings.
-   A reconciliation of quotations, assumptions, duplication checks and outstanding evidence.

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.
