Contractors can have insufficient resources or expertise for certain building works. In these instances, a contractor may decide to hire a sub-contractor to perform part of the works. A subcontractor agreement is a contract between the contractor and a subcontractor.

When engaging a subcontractor, the contractor must conduct due diligence, ensuring the subcontractor is licensed, insured, and capable of meeting the project’s requirements.

In this article, our building contract lawyer explains the legal aspects and things to look out for in a subcontractor agreement.

What is a subcontractor agreement?

A subcontractor agreement is a legal document that outlines the terms and conditions of the relationship between a contractor and a subcontractor. This agreement is crucial in construction and related industries as it clearly defines the roles, responsibilities, and expectations of both parties involved in a project.

This usually occurs when:

the project is too intricate or demanding for the contractor to handle alone necessitating the involvement of a specialist
a contractor’s own labour or equipment resources are limited
a contractor’s own workforce cannot meet deadlines and subcontractors are required to ensure timely completion
hiring a subcontractor for certain tasks is more cost-effective than doing them in-house. This is because subcontractors are often more efficient, have economies of scale, and lower costs.
certain aspects of a construction project may need to comply with specific legal or regulatory standards, and a sub-contractor with the appropriate certification or licensing is required.

In Queensland, building contractors seeking to engage subcontractors must comply with Part 4A (other than domestic building contracts) or Part 1B (for domestic building contracts) of the Queensland Building and Construction Commission Act 1991 (QBCC Act).

Key clauses in a subcontractor agreement

The QBCC Act requires that all subcontracts be in writing.

Key clauses of a subcontractor agreement include:

Scope of Work: This section details the specific tasks and services the sub-contractor is expected to perform. It should be as detailed as possible to avoid ambiguity and the risk of dispute.
Duration of Contract: The agreement should specify the start and end dates of the sub-contractor’s services or detail how the duration will be determined.
Payment Terms: This includes the rate of payment, schedule, invoicing process, and conditions for payment. It may also cover aspects like retentions or hold-backs, and any provisions for changes in the scope of work.
Quality Standards and Compliance: The agreement should state the expected quality standards and any regulatory or legal compliance requirements, especially those specific to Queensland’s construction laws and standards.
Dispute Resolution: The method for resolving any disputes arising from the work or contract, such as arbitration, mediation, or litigation, should be specified.
Termination Clause: Conditions under which the agreement can be terminated by either party, including notice periods and procedures for termination.
Confidentiality and Non-Disclosure: Provisions to protect sensitive information related to the project or the businesses of the involved parties.
Sub-Contracting and Assignment: Conditions under which the sub-contractor may or may not subcontract their responsibilities, and whether the agreement can be assigned to another party.
Warranties and Representations: Any guarantees or representations made by the sub-contractor regarding their ability to perform the work.
Compliance with Laws: A clause ensuring that all work will comply with relevant laws and regulations, including building codes, occupational health and safety laws, and environmental regulations.
Particulars of the Contract: Including the name and licence number of the building contractor and the address of the land where the building work is being carried out.

It is important both contractors and subcontractors obtain legal advice regarding the drafting and terms of a subcontractor’s agreement.

Remember – Unfair Contract Term laws will apply.

Common disputes regarding subcontractor agreements

Issues that arise in subcontractor agreements often stem from misunderstandings, unclear terms, or the complexities of the construction industry.

Here are some of the frequent challenges and areas of concern:

Unclear Scope of Works: One of the most common issues is a lack of clarity in defining the scope of work. This can lead to disputes over what was agreed upon, especially in terms of work quality, specifications, and deliverables.
Payment Terms and Delays: Issues often arise regarding the timing, amount, and conditions for payment, including delayed payments, disputes over completed work, or retention amounts.
Variations to the Contract: Changes in the project scope or unforeseen circumstances often lead to work variations. Disputes can arise if the contract does not clearly define the process for managing and pricing these changes. Learn more about making variation claims.
Compliance with Legal and Safety Standards: Ensuring compliance with all relevant building codes, safety regulations, and legal requirements is crucial. Non-compliance can lead to legal issues and work stoppages.
Termination Conditions: Conflicts can arise over the grounds for terminating the contract, especially if termination clauses are not clear or are perceived as unfair. Learn more about how to terminate a contract.
Liability and Risk Allocation: Issues regarding who is liable for various risks, including accidents, damages, or delays, can be contentious, especially if the contract does not clearly allocate these responsibilities.
Subcontracting or Assignment Clauses: Problems may occur if a subcontractor further subcontracts their work without permission, or if there are restrictions on the assignment of the contract.
Quality of Work: Disputes over the quality of the work provided by the subcontractor, adherence to specifications, and industry standards.
Communication Breakdown: Poor communication between the contractor and subcontractor can exacerbate issues, especially if there are no clear channels or protocols for communication outlined in the agreement.
Completion Delays: Disputes over project delays, especially if they impact critical deadlines or incur additional costs.

Dispute resolution mechanisms such as negotiation, mediation, arbitration, and litigation as a last resort are often utilised to resolve disputes. We recommend that you contact a construction contract lawyer if you find yourself in a dispute.
