Engineering & construction contracts
Formation, scope, variation, payment, subcontracting, delay and termination issues in construction and engineering agreements.
First job Map the contract chain, governing documents and project stage, then preserve notice, payment, delay and change-order clocks before alleging breach.

Key considerations
The first questions are about urgency, governance and preservation — before collection expands or interviews begin.
- Map the chain — Identify owner, employer, contractor, subcontractors, designer, supervisor and supplier, and locate the signed contract, tender documents and incorporated specifications for each relationship.
- Freeze the project record — Preserve drawings, programmes, site diaries, instructions, approvals, tests, payment certificates, meeting minutes, correspondence, photographs and electronic metadata.
- Locate the live clock — Separate scope or variation, delay, payment, defects, subcontracting, suspension and termination issues; check notice, certification, limitation and dispute-resolution deadlines for each.
- Boundary — This route organises contract administration and entitlement questions. Planning, permits, safety, environmental, employment, title and injury issues may require separate routes.
Direct answer
What this page decides
02
A construction contract dispute is usually a chain-of-documents problem before it is a conclusion about breach. Identify the governing contract and project stage, reconstruct instructions and critical-path impact, then test each entitlement against notice, certification and evidence requirements.

Common failure points
Where files usually break
Relying on a tender summary or purchase order without checking incorporated conditions and document priority.
Treating an instruction as a variation without recording authority, scope, price, programme and reservation of rights.
Allowing site records, programme versions, metadata or defective work to disappear before inspection or testing.
Claiming delay or disruption without separating employer risk, contractor risk, concurrent events and mitigation.
Missing notice, payment, certification, adjudication, arbitration or limitation deadlines while negotiations continue.
Stopping work, withholding payment or terminating without checking contractual prerequisites, security and safety consequences.
Signing a final account, release, settlement or handover certificate before unresolved variations, defects and retention are mapped.
Decision map
Keep the question bounded.
- Map documents, roles and risk allocationBuild a contract matrix showing parties, scope, price, programme, design responsibility, site access, approvals, insurance, security, defects, indemnities, governing law and dispute forum.
- Reconstruct instructions and performanceCreate a dated record of access, design release, instructions, variations, extensions, critical-path events, inspections, tests, payment applications, certificates, defects and mitigation.
- Test entitlement and notice complianceSeparate change, delay, disruption, payment, defects, suspension and termination theories. Match each to contractual notice, measurement, causation, certification, valuation and mitigation requirements.
- Choose resolution and delivery controlsPreserve adjudication, arbitration, court, expert determination, negotiation and security rights while managing ongoing works, payment flow, access, safety, handover and evidence without accidental waiver.
