ABIC Contract Administrator

Contract Administration

Specialist advisory for architects and parties involved in ABIC contract administration across Australia: Sydney, Melbourne, Brisbane, Perth, Adelaide, Canberra, and Darwin

Under ABIC contracts, the architect serves as contract administrator, a role that carries significant responsibilities for the fair and proper administration of the building contract between owner and builder.

Christopher Larcos provides specialist advisory services on ABIC contract administration, drawing on his unique dual qualification as both a solicitor and a registered architect. Christopher has performed the contract administrator role as an architect and advised on it as a solicitor, so the advice addresses both what a certification decision means legally and how it plays out on site.

As an adjudicator under security of payment legislation in New South Wales, Victoria, South Australia, Western Australia, and the Australian Capital Territory, Christopher sees how contract administration failures become payment disputes. His advice therefore identifies the administration failures that cause them, and procedures intended to reduce the risk of them, whether the project is in Sydney, Melbourne, Perth, Brisbane, Adelaide, Canberra, or Darwin.

Christopher’s contract administration advice covers the full scope of the architect’s role under ABIC contracts: assessing progress claims, certifying payments, deciding variations and extensions of time, managing practical completion, and navigating the boundary between administration and advocacy.

The Contract Administrator’s Role Under ABIC Contracts

ABIC contracts are distinguished from other standard-form building contracts by their use of the architect as contract administrator. Under an ABIC contract, the contract administrator has five recurring responsibilities.

Progress claims

Assesses progress claims submitted by the builder and issues payment certificates to the owner.

Variations

Decides variations and determines their value.

Extensions of time

Assesses and decides claims for extensions of time.

Completion and defects

Administers practical completion and the defects liability period.

Independent decisions

Acts independently, not as the owner's agent, in making assessments and decisions.

The ABIC model

This three-party dynamic requires the architect to balance professional obligations against the contractual framework. Getting that balance right is where specialist contract administration advisory adds the most value.

The Master Builders contrast

Master Builders contracts (BC3, BC4) do not appoint an independent contract administrator: the owner assesses claims directly. ABIC adds an independent layer of assessment that benefits both parties when administered correctly.

Common questions

What does an ABIC contract administrator do?

The architect acting as contract administrator assesses progress claims, certifies payments, decides variations and extensions of time, and administers practical completion and defects under the contract.

Is the architect under an ABIC contract the owner's agent?

Not when carrying out assessment and certification functions. The role requires independent decisions within the ABIC framework rather than advocacy for either owner or builder.

Who can obtain contract administration advice?

Advice is available to architects, owners, builders and professional advisers dealing with ABIC procedures, certification decisions or the setup of sound administration systems.

What if contract administration leads to a payment dispute?

Late or unsupported certificates and decisions made outside the contract can become payment disputes, requiring close attention to both the ABIC terms and the applicable security of payment legislation.
