1.3 Construction Activities
This section contains a high level summary about the construction activities of the Project. A more
detailed construction methodology is provided in Chapter 5 of the AEE and the Design Philosophy
Statement (Technical Report 1). The information provided below should be treated as being
indicative only. It is intended to provide sufficient detail on the proposed construction activities to
assess their potential environmental effects and to identify any necessary measures to avoid,
remedy or mitigate those effects, where appropriate.
Detailed work programming will depend on a number of factors, and it is recognised that once the
contract for the Project has been awarded and a contractor is in place, the construction
methodology will be further refined and developed. This will be undertaken within the scope of the
designation and consent conditions which will be in place to manage the environmental effects of
the construction activities. Construction management plans will be informed by conditions of the
designations and consents to ensure all mitigation measures are implemented as required. Should a
contractor wish to undertake construction activities in a manner which is not authorised by the
consents held, appropriate authorisations would need to be obtained at that time.
1.3.1 Construction Programme
An outline preliminary construction programme has been developed and is shown in Appendix H.
Construction of the Project is likely to take 36-48 months with work undertaken on multiple sites
simultaneously at any one time. The outline programme shows enabling works (utilities, property
access roads etc.) and site establishment work being undertaken first, followed by local road
connections with associated structures and embankments. The CSM2 main alignment will also
commence at this time followed by the MSRFL after the rear access roads are complete. Landscaping
and installation of roadside infrastructure, including lighting, barriers and signage, will complete
the programmed works.
1.3.2 Enabling Works
Prior to the commencement of construction of the main alignment works, it is assumed that some
early enabling works will be undertaken, namely:
• relocation of significant existing businesses where required;
• treatment of Transpower’s 66 kV transmission lines around Shands Road / Marshs Road
intersection;
• modification of Orion utility infrastructure;
• modification of Telstra Clear and Chorus underground fibre optic cables;
• construction of Main South Road rear property access roads and accesses;
• construction of local access road connections and accesses;
• water race diversions/ modifications; and
• construction of Southern Woods Nursery access from Waterholes Road.
