Building and construction sites are inherently noisy environments. From heavy machinery and generators to power tools and site vehicles, there are a number of different sources of loud noise on site. While this noise is often unavoidable, exposure to loud noise can be dangerous for on-site construction workers and disruptive to the local community and environment. 

In order to minimise the impact of construction noise, building and construction sites in New South Wales must comply with specific noise regulations. Let’s take a closer look at noise regulations in NSW. 

Construction Noise Restrictions: NSW

Construction-related noise issues are commonly assessed alongside other environmental concerns that may affect nearby residents and businesses across NSW. In New South Wales, the Environment Protection Authority (EPA) is responsible for setting and enforcing construction noise limits with support from local councils across the state. The EPA currently uses the Interim Construction Noise Guideline (2009) to set appropriate conditions in licenses and manage issues relating to excessive noise from construction activities. This guideline is also used by councils to decide whether to approve proposed local construction projects. 

More recently, the EPA prepared a Draft Construction Noise Guideline to modernise and improve the Interim Construction Noise Guideline. A review is currently underway and once complete, the feedback will be used to produce a final guideline to replace the Interim Construction Noise Guideline. Until then, the Interim Construction Noise Guideline is applicable to construction projects and building sites across NSW.   

In addition to the Interim Construction Noise Guideline and the Draft Construction Noise Guideline, the EPA also manages industrial noise in NSW through several other regulations, including:

• The Protection of the Environment Operations Act 1997,
• The Noise Policy for Industry (2017), and
• The NSW Industrial Noise Policy (2000).

These regulations work alongside broader environment operations legislation designed to manage environmental impacts from industrial and construction activities.

Recommended standard hours

Under the Interim Construction Noise Guideline, the current recommended standard hours for construction work are:

Normal construction: 

• Monday to Friday 7 am to 6 pm,
• Saturday 8 am to 1 pm, and
• No work on Sundays or public holidays.

Blasting:

• Monday to Friday 9 am to 5 pm,
• Saturday 9 am to 1 pm, and
• No blasting on Sundays or public holidays.

It’s worth noting that while these hours are recommended, they’re not mandatory. There are often instances where construction work may need to be undertaken outside of these hours. 

Construction outside the recommended standard hours

The Interim Construction Noise Guideline details five categories of works that might be undertaken outside the recommended standard hours, including:

• The delivery of oversized plant or structures that police or other authorities determine require special arrangements to transport along public roads,
• Emergency work to avoid the loss of life or damage to property or to prevent environmental harm,
• Maintenance and repair of public infrastructure where disruption to essential services and/or considerations of worker safety do not allow work within standard hours,
• Public infrastructure works that shorten the length of the project and are supported by the affected community, and
• Works where a proponent demonstrates and justifies a need to operate outside the recommended standard hours.

As a general rule, only construction work undertaken on public infrastructure needs to be completed outside of the recommended standard hours, including during weekends and public holidays where approved exemptions apply. Typically this type of work is required to maintain the operational integrity of public infrastructure, like transport and utilities. This type of work to restore the operation of this infrastructure provides benefits to the greater community that extend beyond just the local residents. For example, emergency work might be needed to fix a burst water main or repair roads that have been damaged by flash flooding.

Local Council and EPA Enforcement Penalties for Non-Compliance and Noise Complaints

Failure to comply with noise restrictions can result in fines issued by local councils or the EPA for breaches of noise regulations. If your site is responsible for continual breaches or a significant breach, you may be issued with a stop work order, which could cause significant disruptions or delays to your project.

In some instances, projects may be granted exemptions or variations to standard noise restrictions. These are often subject to:

• Special conditions: Imposed to reduce noise impacts as much as possible, or
• Public interest: Projects deemed to be of significant public interest may also receive special consideration.

In some situations involving persistent or disruptive offensive noise, regulatory authorities may issue a noise abatement direction under NSW noise legislation.

Draft Construction Noise Guideline: Noise Issues and Good Practice Interactions

While the Draft Construction Noise Guideline is still under review, it has a much greater focus on the need for community engagement throughout all stages of the construction project. 

The Guideline also sets out a number of good practice interactions that should be undertaken before construction begins to help reduce noise complaints and improve community engagement, including:

• Notification: Inform the community through one-way channels (EG. letterbox drops, social media and community briefings), providing details on who is conducting the work, its purpose and expected duration.

• Engagement: Inform the community about proposed activities and invite their feedback for consideration.

• Consultation: Actively engage with the community and regulatory authorities, considering their views to plan feasible and reasonable mitigation measures (EG. through liaison groups and feedback/complaint registers).

Construction noise control best practices

When it comes to cost and results, noise control at the source is one of the most effective methods of minimising the noise impacts from construction activities.

There are a number of best practice options available in terms of controlling noise from plant and equipment, including:

• Using quieter methods
• Using quieter equipment
• Operating plant in a quiet and efficient manner
• Maintaining equipment
• Considering the location of plant and equipment on-site
• Using noise shields and barriers to contain construction noise
