Construction Adjudicator
Construction Adjudication
Registered adjudicator and adjudication advisory services for construction payment disputes in NSW, Victoria, Western Australia, South Australia, and the ACT
Construction adjudication is a rapid, statutory process for resolving payment disputes on building projects. Under the applicable security of payment legislation, an independent adjudicator determines an amount payable on an interim basis, typically within 10 to 15 business days of appointment.
Christopher Larcos is a registered adjudicator under security of payment legislation in five Australian jurisdictions: New South Wales, Victoria, South Australia, Western Australia, and the Australian Capital Territory. He determines payment disputes between builders, subcontractors, owners, and head contractors, providing binding interim determinations on the value of construction work.
Christopher’s dual qualification as a solicitor and registered architect shapes how he adjudicates: he assesses the value of the building work as well as the contractual entitlement to it, whether the dispute involves progress claims in Sydney, variations in Melbourne, defective work in Perth, or delay costs in Adelaide or Canberra.
Beyond his role as adjudicator, Christopher also provides strategic advisory services for parties involved in adjudication, whether preparing an application or a response. His experience on the decision-making side informs practical, outcome-focused advice for parties on either side of a construction payment dispute.

When Is Adjudication the Right Choice?
Adjudication is an interim statutory payment remedy, not a universal substitute for every contractual dispute. Its fit depends on the claim, the available documents, the governing Act and what the party needs the process to achieve.
Often well suited
- A disputed or unpaid statutory payment claim where cash flow is the immediate issue
- A valuation, progress payment or variation issue that can be presented principally through the contract and project records
- A party able to prepare a focused case within the governing Act’s procedural timetable
Consider another route
- The dispute is not within the statutory payment regime or a required procedural step has been missed
- The case depends heavily on oral evidence, extensive factual investigation or numerous interlocking counterclaims
- The principal objective is a final determination of broader contractual rights, damages or non-payment issues
Four questions to test before proceeding
Payment and cash flow
Is there an eligible payment claim, and would an interim payment determination address the immediate commercial problem?
Documents and evidence
Can the entitlement, valuation and response be demonstrated through the contract, claim material, programmes, site records and correspondence?
Statutory timing
Which Act applies, what events have occurred, and are the available notice, application and response periods still open?
Dispute complexity
Can the payment issue be separated and decided on the papers, or does it depend on a broader final dispute that another process is better equipped to resolve?
For the jurisdiction-specific claim, schedule and adjudication sequence, see security of payment advice. If the documents and current stage are known, Christopher can assess whether adjudication is available and proportionate before an application is prepared.
