Demolition works to enable the removal of existing redundant and end-of-life office buildings and a portion of the associated landscaping, carparking and structures including a multi-level carpark. 

The Concept Plan and Civil works have been approved with Civil works commencing in July 2023.

The Housing South DA works have been approved, Mirvac Homes will commence construction of the first stage of homes Treeview, in October 2024 following completion of Stage 1 civil works.

Monday to Saturday 7:00am – 5:00pm. No work on Sundays or Public Holidays.

Due to the nature of the associated plant and equipment required to safely execute these works, there may be instances where out-of-hours deliveries may be required to safely transport equipment, and to ensure compliance with Roads and Maritime Services guidelines for oversized vehicles. Furthermore, services authorities (i.e., Endeavour or Sydney Water) works may take place out-of-hours during quieter network periods.

Please be assured that any out-of-hours activities will require separate approvals prior to works commencing and notification will be provided to ensure adequate notice is provided to residents.

A heavy vehicle access route has been approved via Coonara Avenue from Castle Hill Road through dedicated gates at the entry/exit of the site.

To avoid parking in neighbouring streets, workers will be provided parking onsite and encouraged to utilise public transport. All sub-contractor contracts will clearly outline Council’s conditions of approval about onsite parking. Regular toolbox talks and ongoing site management will also occur.

Whilst Mirvac will do all we reasonably can to enforce this item, if any member of the community can demonstrate sub-contractors parking on Coonara Avenue instead of on site, please contact us on the community information phone number or email.

Furthermore, the size of the site means there is no need to keep trucks outside of the site boundary and as such, there will be no parking or queuing of trucks along Coonara Ave.

Should there be substantiated complaints of workers parking outside the site, the Civil contractor will also be penalised under Mirvac’s contractual agreement.

No demolition truck routes will approach or leave the site from this direction.

The main focus of the demolition works will be within the site; however, there will be certain activities that interface with Coonara Ave.

These activities include the installation of the hoarding and authority services works. Prior to any works taking place outside the site boundary, applications and approval will be sought from Council and the relevant consent authority.

As required under the approved Traffic Management Plan, authorised Traffic Controllers will be used as necessary, and pedestrian and cyclists will have right of way on footpaths. We confirm that any traffic controllers used on site will be accredited and focussed to ensure the safety of the general public and site workers.

All loading and unloading of materials associated with the development works will be undertaken within the site.

Localised works for services connections and installation of hoardings will however require unloading access from Coonara Ave. During these activities, any disruption to Coonara Avenue will be minimised as much as possible and appropriately managed. 

Mirvac is committed to keeping the community informed throughout the entire project. Aside from face-to-face meetings and briefings, drop-in sessions, and door knocks, residents and the wider community will be informed through written notifications and website updates. 

Additionally, the project community engagement team, are always available to take calls or emails via the Community Information Line on 1800 531 535 or coonaracommunity@mirvac.com

Mirvac is required to adhere to a strict set of approval conditions when undertaking works onsite to ensure all works are appropriately managed. To help mitigate the impact to adjoining neighbours, Mirvac will implement the following control measures:

- Hoarding to Coonara Avenue and the western boundary to screen from dust and noise

- Noise and vibration monitors will be set up along the boundary in accordance with the approved Construction Noise and Vibration Plan.

- Dust suppression systems including water misting and sprays will be used during the demolition to help minimise dust migration from the site.

Furthermore, all adjoining residents have been encouraged to obtain a condition report of their property prior to works commencing. A specialist consulting engineer has been engaged to complete these reports.

A condition report records the standard of your property including notes and photos and can be used as a reference should an owner believe their property has been affected by any works.

Dust migration is typically highest during the demolition and civil works phases of the project and as such, Mirvac will have several dust suppression measures in place to help manage the dust generating activities to adjacent residents. These include:

- Controlled site access will be maintained with vehicle wash down / clean down facilities established to maintain access roads

- Wetting down of works areas where required to mitigate generation of dust

- All materials transported from site in trucks are appropriately covered and speeds restricted onsite

- The site perimeter along the western boundary and Coonara Avenue will be encapsulated with hoarding to minimise the egress of dust at the boundary of the site

- Water points will be located around the perimeter of the site and are used during specific activities as required

- Stockpiles will be covered when established and long-term stockpiles will be seeded in accordance with DA requirements

- Roads and the entry point will be cleaned regularly

The conditions of approval that go with the demolition works are extensive and will require Mirvac to strictly comply with them to minimise the impact of approved works. Mirvac is committed to providing regular and ongoing communication with the community and is available to address any queries or concerns that anyone may have.

We look forward to working with the community to minimise impacts where possible. 

Any planned disruptions and/or outages to existing services will require approval by the relevant services authority (ie Sydney Water, Endeavour) prior to works commencing.

Once approved, a separate notification will be issued to any residents affected by the works.

A Noise and Vibration Management Plan has been developed and approved in accordance with Council’s approval conditions for the demolition works.

As per this plan, management of noise limits will be in accordance with those set out by the Environmental Protection Agency’s guidelines for construction noise. To help ensure ongoing compliance, Mirvac will establish and undertake noise monitoring and impose restrictions when high-impact noisy works take place (i.e., introduction of respite periods). Furthermore, localised acoustic treatment, including on machinery and equipment, will help minimise noise where possible.

Mirvac understands, acknowledges, and highly values the important role the remnant Blue Gum High Forest and the Sydney Turpentine Ironbark Forest has in providing critical habitat for local native flora and fauna, in particular the Powerful Owl, and we are committed to its protection.

Since 2015, Mirvac has been led by key ecological expert advice with respect to environmental matters on the site. Ecological values and biodiversity remain a critical consideration at every phase of the proposal, including the preparation of the demolition methodology. Expert consultant advice will continue to guide the process as to what is and isn’t possible.

One of the key elements associated with the approval of the concept plan, is the completion and approval of a Fauna Management Plan by Council prior to any demolition works commencing. The Fauna Management Plan will outline how the site will be managed in relation to habitat and what must be done, pre, during and post any demolition works. It is noted that the Fauna Management Plan is now approved.

The health and wellbeing of fauna is of the utmost importance to Mirvac. A comprehensive and strictly implemented Council approved Fauna Management Plan will ensure the protection of any fauna uncovered during demolition and future construction works.

Ongoing supervision by an independent and experienced project ecologist will allow the identification and careful relocation of any native wildlife prior to and during the removal of any vegetation and/or buildings as part of the development process.

All native wildlife, under the supervision of the onsite project ecologist will be relocated to approved areas within the adjacent remnant forested areas of the site.

Over the last 6 years, Mirvac, through the engagement of independent and experienced ecologists, has undertaken several targeted biodiversity surveys of the site to ensure a thorough understanding of the site's inhabitants. These have greatly assisted in the planning of the development and proposed future family friendly residential community to ensure the ongoing protection of onsite fauna.

No individual Powerful Owls have been observed nesting on the proposed development site, including the construction footprint, during the ongoing targeted survey activities. 

All animals, including pests, will be appropriately managed by either the Council approved Fauna Management Plan or other bespoke management measures that may be required pending what animal may apply. If any community member has a specific query in relation to a particular pest such as rats, please let us know. 

The area of works will be fully fenced to prevent any direct access into the remnant forest. Stormwater Sediment Ponds and swales have also been designed to collect any runoff from the development footprint. The water collected will be stored and treated in accordance with authority requirements and reused onsite or discharged. 

Mirvac is committed to ensuring that the development conserves, restores and enhances the important ecological aspects of the site to create a positive environmental and social outcome. The project will feature a high level of social and environmentally sustainable initiatives and will set standard for public open space. Some of the proposed initiatives can be found on the website.

We have materially improved the environmental sustainability aspects of the development by proceeding to deliver an all-electric community. This means the updated DA plans introduce an all-electric community by removing gas reticulation, ensuring that the new community continues to have a strong focus on sustainability.
