PART D19 DESIGN - ENVIRONMENTAL

The Principal has /will obtain the following environmental authorisations:

(a) Significant Tree removal approvals under the Development Act 1993 for those trees identified as such on drawing no xxxxx:

Examples:

1.1 Noise Assessment Modelling

The Principal has undertaken noise modelling to determine the impact of traffic noise, which is included in Appendix D020.9. This modelling identified the need to mitigate the traffic noise from xxxx.ORThe assessment for road traffic noise must be undertaken in line with the process described in Section 5 of the RTNG. In the event of any conflicts or ambiguities, clarification must be sought from the Principal prior to proceeding.

The modelling and design of the noise treatment must be undertaken by an appropriately qualified acoustic Environmental Specialist.

The model and report must be submitted with the Preliminary and Final design documentation.

The Contractor must undertake an on site assessment and testing of existing (pre-construction) traffic noise levels for potential sensitive receivers and locations.

The Contractor must undertake all noise assessment and modelling to determine, detail and optimise any noise treatments required across the project required to mitigate noise generated from the Works to the levels detailed in the RTNG.

Treatment to buildings must not be used as a noise abatement measure, unless approved in writing by the Principal’s Authorised Person.

1.2 Noise Mitigation and Implementation Plan

A Noise Mitigation and Implementation Plan (NMIP) must be prepared by the Contractor that identifies all assumptions, monitoring and modelling results (including noise barrier height, start chainage, end chainage, total length, predicted noise reductions, material to be constructed with, etc).

The Design of any noise treatments must be in accordance with the RTNG and Part D037.

The Contractor must:
