Project Description:

The project presented a major logistical operation to manage, identify, disconnect and remove the existing services & infrastructure simultaneously undertaking the installation and connection of temporary supplies, implementing new services without effecting security or daily operations of the ATO.

Kerfoot was presented with a significant challenge; to replace the existing Main switchboard and site power Distribution system without any downtime to the ATO. Kerfoot successfully executed a faultless shutdown & changeover in just one weekend returning power to the site earlier than projected.

The preparation, staging and installation practices Kerfoot implemented on this project were meticulous and was 6 months in the planning resulted in a seamless transition without affecting the ATO business The Client was extremely gratified.

The amount of planning, co-ordination and problem solving required to deliver the amount of services adjustment through a trading building has refined our skills and showcases the attention to detail we can provide.
