15 Implementation and monitoring

15.1 Timing of access, landscape and open space initiatives

Landscape installation works will occur progressively throughout the project as project areas and work sites become available.

A portion of the urban design will not be implemented by the Rozelle Interchange Project Team and will be completed in the future by Transport for New South Wales (or their delegate). This area within the Rozelle Rail Yards Parkland (refer to Section 2.10) will be utilised as a construction compound by the proposed Western Harbour Tunnel Project (subject to approval), during late construction and operational stages of the Rozelle Interchange Project. Following the completion of construction works for the proposed Western Harbour Tunnel Project this area will be rehabilitated in accordance with the design presented within this Plan. Further timing regarding this work is provided within the Environmental Impact Statement for the Western Harbour Tunnel project.

15.2 Monitoring and maintenance procedures for the built elements

Prior to the commencement of operation of the Project an Operations and Maintenance Manual will be developed which provides details procedures for the monitoring and maintenance of built elements throughout the Project. Monitoring and maintenance requirements have been summarized in Table 15-1 and will be included in detail in the Manual.
