Western Power HV feeder cable works

The hospital needs a major capital investment to ready it for the next 20 years and enable it to cater for the future health care needs of the community.

The redevelopment is driven by the need to:

• replace aging infrastructure
• improve patient amenity and experience
• maintain the hospital's position as a leading contemporary health care facility
• provide additional clinical capacity required to meet forecast future demand.

This major development will see the construction of a new six-storey clinical building with state-of-the-art operating theatres, in addition to general hospital refurbishment and upgrading of necessary infrastructure.

A HV feeder cable specifically refers to a type of electrical cable that carries high-voltage electricity from a power source (in this case, the Shenton Park sub-station) to a distribution point (i.e. St John of God Subiaco Hospital).

The HV feeder works are a critical component of the broader St John of God Subiaco Hospital redevelopment project. This infrastructure is essential to power the future energy needs of the expanding hospital.

The works involve the installation of a dedicated high-voltage (HV) feeder cable, to be located underground, from the Shenton Park sub-station to the northern/Cambridge Street boundary of St John of God Subiaco Hospital.

Beginning at the Shenton Park sub-station (on the corner of Selby and Lonnie Streets) and concluding at the Cambridge Street boundary of St John of God Subiaco Hospital.

The HV feeder cable will be installed under road verges along the route shown on the map above.

The route will begin at the Shenton Park sub-station, off Lonnie Street, Daglish, and progress along the western side of Stubbs Terrace towards Hay Street and Mouritzen Way, Subiaco. Turning right at Atkinson Road, the cable will be on the southern side of the road, until taking a left turn onto the eastern side of Darbon Crescent and continuing to take a right turn onto the western side of Price Street. There will be another right turn onto the north side of Juniper Bank Way and then a left turn to connect to Harborne Street, on the western side. Finally, the route will follow Cambridge Street, where it will follow the southern side of the street before connecting to the switching station at St John of God Subiaco Hospital.

The HV feeder cable will primarily be installed using horizontal directional drilling, where possible. Open trenching or other methods will be employed when required.

Whilst various routes were considered, this alignment was chosen as the most efficient and least impactful option.

St John of God Subiaco Hospital will fund these works as part of their broader redevelopment project.

The commencement date has not yet been confirmed.

If your property is along the cable route, someone will contact you ahead of works commencing in your area.

We encourage you to register for information updates, including advice on the commencement date, other project information and project updates.   Please see all registration and contact details at the bottom of these FAQs.

The overall construction period is expected to last approximately 18-24 months. When the works are in your area, some minor noise and vibration may be felt temporarily.

Power outages are highly unlikely to occur due to these works.

Whilst the project aims to create as little impact and disturbance as possible, depending on your proximity to the route, you may experience some temporary impact.

If you are situated directly on the HV feeder cable route and on the same side of road, you may notice the installation team and their drilling equipment working on the roadside verge adjacent to your property. Every effort will be made to provide advance notice of when this is likely to occur.

Some minor noise and vibration may be felt in the vicinity and surrounding areas from time to time.

Some traffic management measures may also be required whilst the work is in your area.

The contractor will endeavour to undertake construction works within business hours (i.e. 7.30am to 5.00pm).

If nightworks are required (although very unlikely), it will not take place within residential areas.
