When Whittlesea Smiles Dental Clinic decided to enhance their facilities, they required more than just a builder. The addition of a new dental treatment room within an existing clinic necessitated thorough coordination with specialist dental equipment suppliers, careful planning around live patients, and ensuring that the electrical installation complied with AS/NZS 3003 — the stringent Australian standard for electrical work in patient areas. Completing this project on time was crucial for maintaining the clinic’s operational schedule and patient care.

Detailed Overview of Our Electrical Work Scope
- Comprehensive electrical fit-out of the new dental treatment room featuring solid brick construction with chased walls throughout.
- AS/NZS 3003 compliant installation ensuring proper patient zone cabling, earthing, and seamless equipment coordination.
- Close collaboration with dental equipment suppliers to confirm cable specifications and optimal locations for installation.
- Efficient switchboard upgrade completed overnight to ensure the clinic was operational by the following morning.
- Professional wall plastering upon project completion for a neat finish.
- Pre-wiring of the OPG room in anticipation of future equipment installation.
Here’s how we effectively managed the project.
What Challenges Did We Face with Solid Brick Walls and Specialist Dental Equipment?
The clinic's construction featured solid brick walls, which meant that every cable run required careful chasing into the walls. This intricate process is time-consuming and demands precision, as it must be executed correctly on the first attempt to avoid rework.
Our team collaborated closely with the dental equipment suppliers and installers to ensure that each cable was positioned correctly and met the necessary specifications to control vital components like the dental chair, delivery unit, suction systems, and other essential equipment. In a patient care environment governed by AS/NZS 3003 regulations, the cabling goes beyond merely providing power; it must adhere to stringent standards relating to patient zones, earthing requirements, and equipment compatibility. Any errors could prevent the supplier from commissioning the equipment, leading to delays in the project.
How We Managed a Critical Commercial Switchboard Upgrade at 1:30 AM
The existing switchboard was inadequate for the clinic's needs. It was outdated and non-compliant with current standards. Moreover, the clinic could not afford to experience power loss during operational hours. A switchboard upgrade requires shutting off power, which could mean no patients, loss of revenue, and a negative impact on the clinic's daily operations.
Our solution was straightforward yet effective: we initiated the upgrade at 1:30 in the morning.
We successfully completed the entire switchboard upgrade overnight and, while we were at it, we also plastered the wall cavity to ensure that there was no mess left behind. By the time the clinic opened that morning, all work was finalised, allowing for a seamless transition back to regular operations.
How We Planned for Future Expansion: OPG Room Pre-Wiring
The clinic indicated their intention to add an OPG X-ray room within the next six months. While we had the walls open, we took the initiative to pre-wire for this future installation. This proactive approach ensures that when the equipment arrives, everything is ready for a seamless installation, allowing the clinic to continue providing top-quality care without unnecessary delays.
