What time can a concrete pour start in Queensland?

A concrete pour on a building job in Queensland can start making audible noise from 6.30am, Monday to Saturday, and must not make audible noise after 6.30pm or at any time on a Sunday or a public holiday that falls on a weekday. Those hours come from section 440R of the Environmental Protection Act 1994, the default noise standard for building work. Pouring a house slab or footings is part of building a building, so a pour on a building site sits inside that rule.

Three things can change the answer for a particular site. A council can set its own noise standard in a local law, and the Act's hours are the default where it has not. If the job has a council development permit, its conditions can set narrower hours, such as a 7am start. And the Act has a separate standard for pumps, which may or may not bear on a concrete pump. This guide covers the default hours, how approval conditions change them, why Far North Queensland pours want the earliest legal start, and how to ask for an out-of-hours pour. It is general information, not legal advice.

Queensland's default building work noise hours are 6.30am to 6.30pm on business days and Saturdays, and none on any other day. Section 440R of the Environmental Protection Act 1994 says a person must not carry out building work in a way that makes an audible noise on a business day or Saturday before 6.30am or after 6.30pm, or on any other day at any time. Queensland's Acts Interpretation Act 1954 defines a business day as a day that is not a Saturday or Sunday or a public holiday, special holiday or bank holiday in the place concerned. Cairns Regional Council's noise table shows the same hours for building work.

A public holiday that falls on a Saturday is still a Saturday under the Act's wording, but Cairns' noise table and the approval conditions below list public holidays without that distinction, so plan no pour on any public holiday and ask the council if you need one. The test is whether the noise is audible, not how many decibels it reaches. The Act defines audible noise as noise that can be clearly heard by an occupier of an affected building, from the part of that building most exposed to it. Unlawfully breaching a noise standard carries a maximum penalty of 600 penalty units, or 1,665 penalty units if done wilfully.

The 6.30am building work rule applies to builders, trades and owner-builders. Section 440R says it includes a person carrying out building work under an owner-builder permit, and otherwise does not include a person doing building work at premises that are their own principal place of residence. That exception is about the person doing the work living there. On the Act's wording, a concreter, pump operator or builder you hire is working at someone else's home, so the 6.30am rule is the one to plan around when trades do the pour.

A homeowner working on their own home without an owner-builder permit falls under a different standard, for regulated devices such as power tools, compressors and generators. That standard bans audible noise before 7am or after 7pm on business days and Saturdays, and before 8am or after 7pm on other days. Building work in this part of the Act includes building, repairing, altering, underpinning, moving or demolishing a building, plus excavating or filling for that work. If your pour is not part of a building, such as a stand-alone driveway, ask your council which standard it applies.

The Environmental Protection Act does not name concrete pumps or agitator trucks, so the safe plan is to treat their noise on a building pour as building work noise. Section 440R is about carrying out building work in a way that makes an audible noise, and the Act says making a noise includes causing a noise to be made. A pump running and trucks discharging into it are part of placing the concrete, so a neighbour who can clearly hear them before 6.30am is likely to have a complaint the council will look at. Cairns Regional Council says construction noise is generally dealt with by Council.

The Act also has a separate pumps standard, in section 440T. It defines a pump as an electrical, mechanical or pneumatic pump, including swimming pool pumps and spa blowers, and limits the noise an occupier can let one make. The Act does not say whether that standard applies to a concrete pump on a building site, so ask your council. Whether a particular truck movement or set-up counts is also the council's call, so if your pour depends on it, ask before the day.

If your job has a council development permit, read its conditions, because they can set later hours than the Act. These hours come from council planning and operational works permits, not from every approval: a house slab under a private certifier's building approval may carry no hours condition, so the Act's 6.30am default may be the only limit. Cairns Regional Council's Standard Development Conditions Suite has an approved hours of work condition among its construction management conditions, alongside FNQROC construction bonds: work involving construction plant and equipment of any description may only be carried out on site from 7am to 6pm Monday to Friday and 7am to 1pm on Saturdays, with no work on Sundays or public holidays. Any variation must be authorised by Council before the work starts.

A 2025 Mareeba Shire Council operational works permit follows the same pattern. That Development Permit for Operational Works sets 7am to 6pm on weekdays, 7am to 1pm on Saturdays and no work on Sundays or public holidays, and allows no variation unless Council agrees in writing. These are examples, not a rule for every job: Cairns notes its suite is a standard set its officers may depart from. Your own approval's wording is what binds your site, and a 1pm Saturday finish rules out a long Saturday pour.

An FNQ pour benefits from the earliest legal start because heat shortens the time to place and finish concrete. Cement Concrete & Aggregates Australia (CCAA) says that as concrete temperature rises, the setting time, and with it the time to place, compact and finish the concrete, is reduced. CCAA says precautions are usually recommended once air temperature rises above 30 degrees, particularly with a hot dry wind, and recommends scheduling placement for the cool time of day, such as early morning or late afternoon. CCAA adds that night concreting, where permitted, may suit some jobs. Cement Australia says concrete should ideally be placed and finished in the early morning, before temperature and wind rise and humidity drops.

The Bureau of Meteorology's averages show why the first hour matters. In December, Cairns Aero averages a 31.5 degree maximum and 28.0 degrees at 9am; Mareeba Airport averages a 32.1 degree maximum and 26.5 degrees at 9am. A 6.30am start keeps more of the pour in the cool early morning that CCAA and Cement Australia recommend, and a 7am approval condition takes half an hour of it away. Our hot weather pouring guide covers the rest of a hot day plan, and the 90 minute rule explains why trucks cannot simply wait.

An out-of-hours pour needs lawful authority before it is booked, not an apology afterwards, and the council is the place to ask. Under section 493A of the Environmental Protection Act, breaching a noise standard is unlawful unless it is authorised, and one of the listed authorities is a development condition of a development approval. The Cairns and Mareeba conditions above both route variations through Council, in advance or in writing. This guide could not find a published stand-alone out-of-hours noise permit for building work in Cairns or Mareeba, so ask your council what applies to your site.

1. Check whether the job has a development approval and read its hours of work condition.
2. Work out the pour window with the builder, concreter and pump: start time, volume and expected finish.
3. If the window falls outside the approved hours, ask the council in writing for a variation, with the reason (for example heat, traffic or a large continuous pour) and the hours sought.
4. Book the concrete and the pump only once you have the council's answer.
5. Tell the neighbours the date and start time.

Pouring between 6.30am and 6.30pm does not make every noise acceptable. Cairns Regional Council says creating noise within prescribed levels and times can still be a nuisance if it is excessive. When it investigates a complaint, Cairns considers the amount of noise; its frequency, duration, time, characteristics and qualities; how sensitive the surroundings are; and the views of other neighbours, and it may monitor the noise. That answers the common question of what level of noise is a nuisance: there is no single decibel figure for building work, and the council weighs the whole picture. Because the council weighs the time of the noise and the sensitivity of the surroundings, where the pump and trucks set up matters as well as when they start.

Tell the neighbours about an early pour before the day, in person or with a note in the letterbox. Cairns Regional Council asks people to think about the time, duration and volume of noisy activities, to do noisy work as far from the neighbour's house as possible or use noise barriers, and to talk to neighbours before involving authorities. For a pour, that translates into a short checklist:

• Give the date, the planned start time and roughly when the pump and trucks will leave.
• Say where the pump will set up and where trucks will queue, and keep them away from bedroom windows where the site allows.
• Mention any footpath or road set-up, and check whether it needs a permit first in our guide to concrete pump road permits.
• Leave a phone number for the builder or person in charge of the site on the day.
• If the pour is called off, tell the neighbours too, so they are not waiting for it.

Queensland's Concrete Pumping Code of Practice 2019 expects a time schedule to be set before a major pour, based on a realistic assessment of the time to complete, with an allowance for restricted work times under local authority rules. That is where the noise hours meet the pump booking. Far Northern Concrete Pumping is based in Mareeba and pumps residential, commercial and civil pours across Cairns, the Tablelands and the rest of Far North Queensland, with 31m, 28m and 20m boom pumps and a line pump. Tell us the site, the volume and the earliest start your approval allows, and we can plan arrival and set-up so the pump starts as soon as the hours allow, with the trucks, outriggers and boom set-up inside the permitted hours too. The safety paperwork that sits alongside the schedule is covered in our concrete pumping SWMS guide.
