05Construction Contracts & Claims

Quick answer

Allocate design, cost, programme, payment, change, completion and defect risk before mobilisation — and preserve the project’s contractual position during delivery.

In this workstream

01Who this may suit

  • a developer appointing architects, engineers and other consultants
  • a project procuring a main contractor or design-and-build team
  • an investor acquiring a project already under construction
  • a lender reviewing bankability and step-in protection
  • a developer facing delay, variations, payment disputes or abandonment
  • or an owner managing completion, defects or warranty claims.

03Potential scope of support

Depending on the agreed engagement, support may include:

Professional appointments

  • architect, engineer and specialist appointments
  • scope and deliverables
  • design responsibility and coordination
  • statutory professional roles
  • duty of care and standard of performance
  • fees and additional services
  • programme and information obligations
  • professional indemnity insurance
  • intellectual-property rights and licences
  • novation or assignment
  • termination and handover
  • and lender direct agreements.

Procurement and pre-contract documents

  • tender conditions
  • confidentiality and data-room rules
  • contractor pre-qualification
  • responsibility matrix
  • letter of intent or early-works agreement
  • contract negotiations
  • and coordination of drawings, specifications, bills, schedules and commercial clarifications.

The contractual documents should establish an order of precedence and a process for resolving inconsistencies.

Construction contract

  • parties and authority
  • scope of work and exclusions
  • design responsibility
  • contract documents and priority
  • site access and conditions
  • price and price-adjustment mechanism
  • payment, certification and set-off
  • programme, milestones and completion date
  • instructions and variations
  • extensions of time
  • delay consequences and contractual penalties
  • suspension and termination
  • subcontracting
  • law, dispute procedure and forum
  • and continuing obligations after termination.

Security, insurance and risk

  • advance-payment security
  • performance bonds or guarantees
  • retention
  • parent-company support
  • contractor and project insurance
  • professional indemnity insurance
  • site and third-party risks
  • risk of loss and care of the works
  • lender requirements
  • and release, reduction and expiry of security.

The amount, form, issuer, expiry, claim conditions and release trigger should be checked for each instrument.

Project administration

  • employer, project manager and contract-administrator authority
  • communications and notice addresses
  • instructions
  • applications and payment certificates
  • programme updates
  • design information and approvals
  • variations and quotations
  • claims and substantiation
  • meeting records
  • and document-retention procedures.

Rights may depend on timely notices and evidence. The site-management system should reflect the signed contract rather than a generic reporting process.

Completion, handover and defects

  • tests and commissioning
  • practical or contractual completion criteria
  • snagging and outstanding work
  • as-built information
  • manuals, certificates and keys
  • use and opening requirements
  • transfer of risk
  • retention or bond release
  • defects-liability procedure
  • statutory and contractual warranties
  • final account
  • and final completion.

Claims and disputes

  • delay and disruption
  • extension of time
  • loss and expense
  • variations and valuation
  • non-payment or overpayment
  • defects and incomplete work
  • professional negligence
  • suspension or abandonment
  • termination
  • security calls
  • settlement
  • mediation, arbitration or litigation
  • and urgent protective measures.

Dispute strategy should consider the effect on construction progress, finance, sales, insurance and limitation periods.

04Potential deliverables

  • project legal-contracting strategy
  • consultant appointment suite
  • tender and construction contract
  • design-responsibility and interface matrix
  • security and insurance schedule
  • lender direct agreements
  • standard instruction, payment and notice templates
  • change-control and claims protocol
  • completion and handover checklist
  • defects and warranty tracker
  • and claim, defence or settlement documentation.

05What depends on the project

  • traditional, design-and-build, construction management or package procurement
  • design maturity at contract date
  • fixed, measured, target or reimbursable price structure
  • phased possession or completion
  • contractor financial strength
  • imported materials and supply-chain risk
  • lender and buyer commitments
  • operator or brand standards
  • and dispute-resolution strategy.

07Frequently asked questions

Common questions developers ask at this stage.

Can works start under a letter of intent?

Potentially, but the document should define the limited authorised work, maximum value, programme, insurance, ownership of design and materials, payment, termination and transition to the main contract.

Is a fixed-price contract always fully fixed?

No. The actual risk depends on the defined scope, provisional items, measurement rules, variations, price-adjustment clauses, employer changes, unforeseen conditions and relief events.

Can the contractor complete part of the design?

Potentially. The contract and professional appointments should identify the design scope, criteria, review process, statutory responsibility, intellectual property, insurance and interface with the employer’s design team.

What should happen when a variation is requested?

The contract should define who may instruct a change, the required quotation and records, the effect on price and time, emergency procedures and what happens if the valuation is disputed.

Does practical completion end the contractor’s obligations?

No. Outstanding works, defects, documents, warranties, final account and other obligations may continue. The specific consequences depend on the contract and applicable law.

Should a developer wait before giving notice of a claim?

No general answer applies. The signed contract may impose short notice periods or evidence requirements. The issue should be reviewed promptly so that rights are not unintentionally prejudiced.
