What is Quantum Meruit?

Quantum Meruit, a Latin term meaning “as much as he has earned”, is a legal principle used when a person expects payment for work done outside a contractual agreement. 

In the context of construction in New South Wales, it often arises when a builder completes work that wasn’t initially outlined in the contract. Instead of a pre-agreed price, the builder seeks compensation based on the actual value of the work done. It’s a way to ensure fairness, ensuring that builders are remunerated for additional efforts, while homeowners pay a just amount for unexpected changes or additions.

Conditions for Quantum Meruit

For a successful Quantum Meruit claim in NSW, certain conditions must be met:

  • Firstly, the work in question should be beyond the contract’s original scope. 
  • Homeowners must be aware of the variation as it’s executed, understanding it’s outside the contract. 
  • They should also know that the builder expects payment for this extra work.
  • Lastly, the builder must demonstrate that the amount claimed represents the fair value of the additional work, ensuring a just compensation for both parties.

Understanding Contract Variations

Contract variations refer to changes or adjustments made to the original terms of a construction contract. Under the ABIC Simple Works Contract for Housing in NSW, variations can encompass alterations in the scope of work, materials used, workmanship quality, or even specific details of the project.

It’s crucial for homeowners to understand that any variation must be in writing and signed by both parties, as mandated by the Home Building Act 1989 (NSW). This ensures transparency, mutual agreement, and protection for both the homeowner and the builder against potential disputes.

The ABIC Simple Works Contract is a comprehensive framework tailored for housing projects in New South Wales. It meticulously outlines the rights, obligations, and processes for both homeowners and builders. 

Key sections like ‘Variation to the Works’ and ‘Claims to Adjust the Contract’ provide clarity on how changes to the original contract are handled. This contract ensures that all parties are on the same page, promoting transparency and reducing the potential for disputes.

Fair Value Assessment in Quantum Meruit

One of the pivotal aspects of Quantum Meruit is determining the ‘fair value’ of the work done. This isn’t about the contract’s pre-agreed price but the genuine worth of the additional work. 

In NSW, especially under the ABIC framework, the builder must provide evidence of this value. It’s a balancing act, ensuring builders are adequately compensated while homeowners aren’t overcharged. 

Factors considered include:

  • the quality of work
  • the materials used
  • the market rate for such tasks

Homeowners should be vigilant, understanding this assessment to ensure they’re paying a just amount for any extra work.
