Before remedial work changes the condition, consider photographs with scale/location, drawings and specifications, inspection/testing records, expert or consultant inspection, samples where appropriate, access offered to the other party, the proposed remedial method, tender/invoice evidence and a record of why urgent work could not reasonably wait.
Start with the contractual requirement
A defect is not simply something that looks unsatisfactory. The first question is what the contract, specification, drawing, standard or duty required. Preserve the relevant revision of those documents and the records showing what work was actually carried out.
Document the condition before it changes
Photographs should show context as well as close detail. Record location, date and what is being photographed. Where measurements matter, include scale. Video can be useful for movement, water ingress or operational defects. For concealed work, record opening-up carefully.
If the issue is likely to require specialist opinion, obtain advice on whether samples, tests or an inspection should occur before removal.
Access and opportunity to inspect
Where it is safe and commercially sensible, consider whether the other party should be given a reasonable opportunity to inspect before remedial works. The contractual position, urgency and risk of further damage matter. Keep written records of access offered, accepted or refused.
Preserve the remedial decision-making trail
Record why the chosen remedial solution was necessary and proportionate. Keep alternative proposals, consultant recommendations, tenders, purchase orders, invoices and site records. A later dispute may concern not only whether there was a defect but whether the remediation and its cost were reasonable.
Urgent safety or mitigation work
Evidence preservation should not prevent necessary safety or mitigation measures. If work must proceed urgently, create the best contemporaneous record reasonably possible and explain why delay was not practical. The legal analysis should fit the real project risk, not the other way around.
Expert evidence and litigation
A consultant who helps diagnose and remedy a problem performs a different role from an independent expert giving evidence to the court. If TCC litigation is contemplated, consider early whether formal expert evidence may be needed and preserve material that allows an expert to understand the original condition.
Quick questions
Should remedial work be delayed until lawyers are involved?
Not if safety, damage or mitigation requires prompt action. The key is to combine necessary work with proportionate evidence preservation.
Are photographs enough?
Often not. Drawings, specifications, test results, inspection records, samples, witness evidence and the remedial cost trail may all be needed to establish breach, causation and loss.
Can defects disputes go to adjudication?
Yes, qualifying disputes can be adjudicated, including technical defects and remedial-cost issues. The compressed timetable makes early evidence organisation particularly important.
Basis of this guidance
This is practical case-preparation guidance rather than a statement of a specific legal rule. Contract terms, procedural rules and expert-evidence requirements should be checked for the particular dispute.
