Any discharges from the site will be strictly controlled to ensure hazardous materials and
contaminants are contained to authority requirements and do not pollute the council storm water
system. The Main Contractor will have within its standard procedures, the requirement of spill kits for
hazardous materials also including environmental audits that review the usage and storage of
hazardous materials onsite.
Dewatering

Dewatering may not be required on this site apart from localized dewatering of footing
excavations if necessary.


6.5       Noise and Vibration Management
Particular care will need to be taken during the construction of each phase of the project to control
noise and vibration. Work methodologies and plant selection for demolition and excavation will be
reviewed to determine the most practical and program-effective solutions for these works. This active
approach will mitigate the potential for human discomfort and noise and vibration disruptions to
surrounding key stakeholders.
Prior to the commencement of any works onsite a noise and vibration management plan may be
developed by the Main Contractor in consultation with the Stakeholders to develop strategies for the
mitigation of noise and vibration generated by the works.
In order to help meet the noise and vibration requirements of the site, baseline testing may be carried
out and existing operational levels identified. Early identification of baseline levels will enable
subcontractor methodologies to be specifically tailored to ensure the benchmarks are not exceeded.
Vibration and noise generating activities will be coordinated and undertaken in consultation with the
appropriate parties and carried out during the subsequent agreed periods.

Work methodologies and plant selection will be reviewed to mitigate the potential for noise and
vibration from the new works being loaded onto the surrounding structure.
Work practices that minimize noise and vibration will be used wherever possible. These include but are
not limited to the following:

      Flexible working hours avoiding noisy work during peak business operation times
      Plant and equipment selection to reduce noise where possible
      Plant and equipment fitted with silencers where possible
      Diligent housekeeping to minimize the generation of dust
      Methodology development aimed at finding alternatives capable of reducing noise and vibration
       where possible
      Location of major plant such as cranes away from noise and vibration sensitive areas
       where possible.


The following items outline some of the expected Main Contractors key control measures that
may be applied during the demolition and construction phase to assist with noise reduction:


      Plant known to emit noise strongly in one direction would, where possible, be orientated so that
       noise is directed away from noise sensitive areas.
      Machines fitted with engine covers would be kept closed when not operating.
      The height materials are placed either into or out of trucks would be limited where possible.
