Payment Claim — Security of Payment (Australia)

Create a legally compliant Australian Construction Contract covering progress claims and payment schedules under the Security of Payment Acts (NSW Building and Construction Industry Security of Payment Act 1999, VIC Building and Construction Industry Security of Payment Act 2002, QLD Building Industry Fairness (Security of Payment) Act 2017), practical completion, defect liability, liquidated damages, retention at 5%, builder's licence requirements (QBCC/VBA), public liability and construction all risks insurance, home warranty insurance, WHS obligations under the Work Health and Safety Act 2011, and dispute resolution including statutory adjudication. Suitable for residential new builds, renovations, extensions, and commercial construction projects across all Australian states and territories.

A Variation Order is a formal written instruction that changes the scope, price, or programme of a building contract. Under Australian standard form contracts — including the HIA New Homes Contract, the Master Builders Association Contract, and the Australian Standard AS 4000-1997 General Conditions of Contract — all variations to the agreed scope of works must be in writing and signed by both parties before the varied work is commenced. This template generates a compliant Variation Order document suitable for use under any of these standard forms. Variations are one of the most common sources of dispute in Australian construction projects. Without a properly documented Variation Order, contractors may find themselves unable to recover the cost of additional work they have performed, and principals may find themselves unexpectedly liable for amounts they did not authorise. The courts have consistently held that where a construction contract requires variations to be in writing, oral instructions to perform additional work do not give rise to an enforceable contractual entitlement — although claims in restitution (quantum meruit) may still be available in some circumstances. Under AS 4000-1997 clause 36, the Superintendent (the independent contract administrator appointed by the Principal) has the authority to direct a variation. The direction must be in writing, and the Superintendent must assess the value of the variation in accordance with clause 40.4 — by reference to the rates and prices in the contract where applicable, or on a fair and reasonable basis where no applicable rates exist. The Contractor is entitled to claim the assessed value of the variation as part of the next progress claim. For residential construction under HIA contracts, the requirements are governed by the relevant state home building legislation. In New South Wales, the Home Building Act 1989 (NSW) and the Home Building Regulation 2014 impose strict requirements on variation terms for residential contracts: the variation must be in writing, must describe the work and the price change, and must be signed by the homeowner before work begins. In Victoria, the Domestic Building Contracts Act 1995 (VIC) similarly requires written variation orders signed by the owner. In Queensland, the Queensland Building and Construction Commission Act 1991 and the Domestic Building Contracts Act 2000 impose equivalent requirements. This Variation Order template covers all essential elements: the unique variation number for tracking purposes; identification of the parties and the original contract; a detailed description of the variation to works (additions, omissions, or substitutions); the pricing basis and adjusted cost (with GST shown separately); the cumulative variation total and revised contract sum; any extension of time required; WHS considerations under the Work Health and Safety Regulation 2017; a list of attached documents including variation sketches and updated specifications; and execution blocks for signature by both parties. The template also prompts consideration of Work Health and Safety obligations. Under the Work Health and Safety Regulation 2017 (Cth) and equivalent state regulations, a Safe Work Method Statement (SWMS) is required for all high-risk construction work. Any variation that introduces new high-risk work — such as work at heights above 2 metres, excavation, or work near energised electrical installations — requires an updated SWMS to be prepared and signed by all workers performing that work before it commences.

A Certificate of Practical Completion is one of the most important documents in Australian construction law. Issued by the Superintendent (or an independent certifier) under AS 4000-1997 clause 42, or by the parties under HIA or Master Builders Association contracts, it formally records that the construction works have reached practical completion — the point at which the works are substantially complete and fit for their intended purpose, even though minor outstanding items or defects remain. The practical completion certificate triggers a cascade of legal and financial consequences that fundamentally alter the rights and obligations of both parties. It marks the commencement of the Defect Liability Period (typically 12 months for residential works and 6 to 12 months for commercial projects), during which the contractor is obliged to remedy notified defects at its own cost. It triggers the release of the first tranche of retention money — typically 50% of the total retention held — which must be paid to the contractor within the timeframe specified in the contract or the applicable Security of Payment Act. It causes liquidated damages for delay to stop accruing (unless practical completion was achieved after the date for practical completion, in which case the delay period for liquidated damages purposes is fixed by the certificate). And for residential building work, it marks the point after which home warranty insurance covers are restructured. The legal test for practical completion in Australia has been settled since Multiplex Constructions Pty Ltd v Abgarus Pty Ltd (1992) 33 NSWLR 504, in which the NSW Supreme Court held that practical completion is reached when the works are complete for all practical purposes — meaning they can be used by the owner for their intended purpose, with only minor outstanding items that do not affect safe use or beneficial occupation. Practical completion does not require absolute perfection, and a Superintendent is not entitled to withhold the certificate merely because minor defects exist that can be remedied during the Defect Liability Period. However, the line between 'minor' and 'major' outstanding items is often contentious. Australian courts have held that items which prevent the use of the building for its intended purpose (for example, incomplete fire protection systems, missing essential fixtures, or structural defects) cannot be characterised as minor items. Where the Superintendent unreasonably withholds a practical completion certificate, the contractor may be entitled to claim that practical completion occurred on a particular date regardless of the certificate, and to claim the retention and final payment accordingly. This template generates a comprehensive Certificate of Practical Completion for use under any Australian standard form construction contract, covering all key elements: the certificate date; the parties and Superintendent; the contract type (HIA, MBA, AS 4000-1997, or AS 4300-1995); the site address and contract sum; the original, revised, and actual dates for practical completion; a description of the works at practical completion; a schedule of outstanding minor items; the Defect Liability Period and its expiry date; the retention release schedule and final payment obligations; liquidated damages implications; and the execution blocks for the Superintendent, Principal, and Contractor.

A Construction Change Order is a formal written document that records and authorises a change to the agreed scope of works, contract price, and/or programme under a building contract in Australia. It is the most comprehensive form of variation document used in Australian construction projects — broader than a simple Variation Order in that it explicitly addresses not only price adjustment but also programme impact, Work Health and Safety obligations under the Work Health and Safety Regulation 2017, and the SWMS (Safe Work Method Statement) requirements for any high-risk construction work introduced by the change. Change Orders are essential tools of project administration on any construction project of significance. They provide a formal, auditable record of every agreed change to the contract, enabling both parties to track the cumulative impact of changes on the contract price and programme over the life of the project. Without a documented Change Order, disputes about the scope, price, and timing of changes are almost inevitable — particularly on complex projects where changes to one element of the works may have knock-on effects on other elements, on specialist subcontractors, or on the overall programme. For residential building contracts under HIA and MBA standard forms, a signed written Change Order (called a 'variation' under the HIA contract) is not merely good practice — it is a legal requirement. The relevant home building legislation in each Australian state and territory requires the builder to obtain the homeowner's written consent to variations before the changed work commences. In New South Wales, the Home Building Regulation 2014 prescribes the minimum content for a residential building variation, including the description of the change, the price change, and the homeowner's signature. A builder who commences varied work without a signed written variation order may be unable to recover the variation price from the homeowner, even if the homeowner verbally requested the work. For commercial construction under AS 4000-1997, HIA commercial contracts, or bespoke construction contracts, the Change Order provides the mechanism for the Superintendent to direct a variation and for both parties to agree the cost and programme impact. The Change Order should be issued and signed before the changed work commences, except in emergencies where the work must proceed immediately for safety or to prevent damage to the works. In those cases, the Change Order should be executed as soon as possible after the emergency work is performed. This template covers the full scope of a well-prepared Change Order: the project identification details; the parties and their authorised representatives; the original contract details including contract type and sum; a detailed description of the scope change including additions, omissions, and substitutions; the cost impact broken down into additions and omissions with GST shown separately; the cumulative Change Order total and revised contract sum; programme impact including any extension of time to the date for practical completion; WHS obligations including the SWMS requirements for high-risk construction work under WHS Regulation 291; a list of attached documents; and execution blocks for both parties. The cost and programme tracking features of this Change Order template make it particularly suitable for projects where multiple changes are expected. By recording the cumulative total of all previous Change Orders and the revised contract sum, it provides both parties with a clear, up-to-date picture of the financial position of the project at every stage.
