Development in Far North Queensland is approved with noise conditions attached, and the approval usually depends on acoustic evidence lodged up front. We measure the existing environment, model the development to ISO 9613-2, assess it against the criteria that apply, and set out the controls needed to comply — then help manage construction noise and close out the conditions once the project is built.
When council asks for a noise impact assessment with a development application, or issues an information request about noise; when a commercial or industrial use will bring plant, deliveries or extended hours close to homes; and when construction will run near homes, schools or hospitals.
Criteria come from the planning scheme, the conditions of approval and the Environmental Protection (Noise) Policy 2019. Measurement follows AS 1055 and prediction follows ISO 9613-2, with adjustments for tonal and low-frequency character where the plant has it.
Building work is restricted under the Environmental Protection Act 1994 to 6:30am–6:30pm Monday to Saturday, with none on Sundays or public holidays, unless an approval says otherwise. Structural vibration is assessed against DIN 4150-3 and BS 7385-2.
For a development application: a noise impact assessment covering the measured baseline, the noise model, predicted levels at each receiver by day, evening and night, the assessment against criteria, and the mitigation required.
For construction: a noise and vibration management plan setting out working hours, plant, predicted levels, monitoring and the complaint response procedure.
Baseline monitoring needs a representative period of unattended logging — usually a week or more, so that weekday and weekend conditions and a range of weather are both captured. Modelling and reporting follow once the data is in.
A fixed fee per stage — baseline monitoring, modelling and assessment, and any response to council's information request — quoted from the site plan and the plant schedule.
Sometimes, for a small change on a well-understood site. Usually the criteria are set relative to the existing background level, so measuring it is the only defensible starting point.
ISO 9613-2 predicts levels under conditions favourable to propagation — downwind, or with a mild temperature inversion. That is the conservative case regulators expect, and it is how the model should be read.
Yes. We review the original assessment, address the specific items council has raised, and say plainly where the original approach needs to change.
