The $1.7 billion project involved the construction of a four-lane, 40-kilometre freeway link between the M1 Pacific Motorway, west of Newcastle, and the New England Highway. It was one of the biggest road infrastructure projects to be built in the Hunter.
The client engaged Advitech’s environmental team to quantify noise impacts associated with the new haulage route in order to justify the modification to authorities. Its initial brief was to undertake an assessment on the basis of the NSW Construction Noise Guideline, requiring a series of activities:
- background monitoring for 7-14 days
- determination of construction noise management criteria
- preparation of a model to evaluate construction noise levels
- assessment of impact
- documentation and quantification of actions to minimise impacts
- reporting on assessment findings.
The client developed the scope of works on the basis of standard advice from the regulators. The requirement for long-term ambient noise monitoring meant it would have taken up to three weeks to execute the methodology required by this style of assessment.
With 27 years of experience across all aspects of noise monitoring and assessment, Advitech’s environmental team had the knowledge and insight required to not only meet the needs of the project, but also take a bigger-picture view and propose an alternative solution to the client’s needs.
Discussions with the client allowed our acoustic specialists to gain an understanding of the actual objectives of the project. They undertook a review of the extensive assessment literature already published for the project. This yielded existing monitoring data that could be used to develop noise management criteria for the impacted receiving environment – negating any need for additional background monitoring. Reducing the scope of work not only reduced the cost of works for the client, but it also reduced the timing turnaround for the assessment by up to two weeks.
Undertaking the assessment on the basis of existing noise monitoring data, Advitech’s environmental team was able to develop the model, assess the impacts, provide recommendations and issue a brief report in support of the proposed modification within a very quick timeframe. Removing the need for ambient monitoring and associated equipment hire and labour costs also saved the client money.
