Delay & defects

Delay and defects disputes depend on records, causation and technical evidence.

HQ Law advises on extension-of-time, liquidated-damages, disruption, defects and remedial-work disputes, combining legal analysis with Chris Hough’s engineering background.

Records to preserve

Programmes and updates, progress records, instructions, RFIs, notices, photographs, expert reports, defect schedules, remedial records, cost evidence and correspondence.

The strength of any position depends on the actual contract, notices, evidence and procedural history. HQ Law can review the material, identify the legal and commercial issues and advise on the proportionate route forward.

Possible routes

  • Focused correspondence or negotiation
  • Construction adjudication where available and appropriate
  • Mediation or settlement discussions
  • Litigation or arbitration where the contract and circumstances require it
Technical evidence

Delay and defects disputes are usually won or lost on disciplined records.

Delay disputes require more than a programme printout. The parties usually need to identify the contractual completion obligations, notices, contemporaneous programmes, critical events, mitigation steps and the causal link between an event and the time or cost claimed. Defects disputes similarly depend on establishing what was required, what was built, why it differs, the consequences and the reasonable cost or method of remediation.

Where remedial work is urgent, evidence of the original condition can disappear quickly. Photographs, surveys, expert inspections, samples where appropriate, access records, remedial proposals and cost records should therefore be considered before destructive or irreversible work begins.

What evidence is useful in a delay claim?

Baseline and updated programmes, progress records, notices, meeting minutes, instructions, labour/plant records, photographs and correspondence explaining when events occurred and their effect on critical activities.

What evidence is useful in a defects claim?

The specification and drawings, inspection/testing records, photographs, expert or consultant reports, samples where appropriate, remedial scope, tenders/invoices and evidence of access or opportunities to inspect.

Should repairs wait for the dispute?

Not necessarily. Safety and mitigation may require prompt action, but the evidential position should be considered first so that the condition and cause are documented before remedial work changes them.

Adjudication or litigation?

That depends on the contract, the issue, the evidence and the remedy required. Adjudication can provide a rapid temporarily binding decision; complex technical claims may also require TCC litigation, arbitration or negotiated settlement.
