Constraints Awnings located along many of the city centre streets Concept design provisions Designing the traffic capacity improvements to avoid awing impacts or the introduction of traffic closer to awning façades. 3.2.4 Urban design principles A number of urban design principles have been adopted for the proposal and are proposed to be carried through to detailed design. These principles reflect the type and scale of the work plus its location in an urbanised historic environment. They also reflect a number of city centre planning policies (such as the Access Strategy) and development controls (refer to Chapter 4) that focus on key built form and urban design themes. The principles comprise: Ensure design consistency within the existing road corridor and with other projects proposed under the Access Strategy Protect and enhance the streetscape where possible Retain the city’s active frontages (refer to Table 4-2) Protect the city’s footpath awnings and colonnades (refer Table 4-2) Maintain the pedestrian priorities within the city streetscape (refer Table 4-2) Maintain the special characteristics of key areas and their associated themes as described in the City of Sydney Development Control Plan 2012 (Sydney DCP) (refer to section 4.2.2) Improve signage layouts to improve navigation and way-finding (ie the user experience of orientation and choosing a path within the built environment) (which is set out as an objective of the Access Strategy Retain the kerbside planted trees where possible (refer to section 6.6.2) Enhance the city’s historic urban themes the individuality of key precincts and neighbourhood (refer to section 6.6.2) Promote traffic mode shifts to reduce reliance on the car, as per the NSW Government’s Greenhouse Gas Plan (refer to section 6.13.1). The proposal would achieve the above principles by: Developing the detailed design to be consistent with the other Access Strategy projects Ensuring the concept design and materials selection has identified, avoided or safeguarded against impacts on the key heritage assets that exist within the city centre (refer to section 6.3.2) Ensuring the introduced or altered road furniture adds to the city’s landscape character (refer to section 6.6.2) Minimising tree loss to an absolute minimum to achieve the required design outcomes whilst maintaining the value the trees bring to the urban landscape (refer to section 6.6.4) Ensuring a context-sensitive design has been adopted in all locations given that the affected roads are places that have high pedestrian counts and in some instances are located adjacent to places that provide recreational, community and socioeconomic value (refer to section 6.4.4) Ensuring the design has considered how it promotes the public transport (integration), cycling and walking initiatives introduced under the Access Strategy (refer to section 6.1.3) Maintaining connectivity during construction and once the proposal is operational considering the predicted increase in the number of trips made into the city over the coming years (refer to section 2.1 and section 6.1.2) Maintaining the public domain by removing visual clutter and improving navigation and way-finding (refer to section 6.1.3). Sydney City Centre Capacity Improvement 131 Review of Environmental Factors
3.3 Construction activities The likely construction method, staging, work hours, plant and equipment requirements for the proposal are described in this section. An indicative construction plan and method are also provided. The construction contractor(s) would prepare the detailed construction plan and method once the proposal’s detailed design is complete. The construction plan and method would allow for multiple work sites to be constructed at the same time. It would also account for the interface between the different Access Strategy projects and would consider the construction staging required to maintain traffic flows around the city centre; particularly during peak periods. The actual construction method may vary from the description provided in this section due to the identification of additional constraints pre-construction, ongoing detailed design refinements, feedback from community consultation, and construction contractor requirements/limitations. 3.3.1 Work method The works would be carried out under a construction environmental management plan (CEMP). The following Roads and Maritime quality assurance specifications (QA specifications) would be used to develop the CEMP: G36 Environmental Protection (Management System) (Roads and Maritime, 2014) G38 Soil and Water Management (Soil and Water Management Plan) (Roads and Maritime, 2014) G40 Clearing and Grubbing (Roads and Maritime, 2012). Works would only take place within the areas specified in this REF. They would be completed in accordance with the safeguards and management measures included in this REF (refer to Chapter 7), the subsequent response to submissions report, the Roads and Maritime decision report, and any Roads and Maritime environmental specifications. Construction method and activities A number of activities would be required to construct the proposal as described below. Broadly, the construction activities would be carried out in five sequential stages: Stage 1: site establishment Stage 2: modification and alteration works Stage 3: signage and traffic signal modifications as well as bus lane markings Stage 4: reinstatement, refurbishment and post works Stage 5: site hand back. As noted in section 3.3.3, the construction staging within each work site and between work site locations would be defined by the construction contractor. Most likely, in the larger work sites, various stages of works would be going on concurrently. It is also proposed that several work sites would be constructed simultaneously. Table 3-2 shows the general construction activities and methods associated with each of the proposed traffic capacity improvements and supporting work in relation to the above five construction stages.
