Electrical and lighting

Tonkin’s electrical and lighting experts are skilled in lighting and electrical design for a range of infrastructure projects, with specialisations in road and public realm lighting projects. Well-planned electrical and lighting design is vital for operational efficiency and functionality, safety and visual appeal.

Electrical and lighting design
With experience delivering electrical and lighting solutions for SAPN, State Government, Local Government and urban infrastructure clients, Tonkin provides innovative and cost-effective electrical designs that comply with Australian Standards, SA Power Networks, council and Department for Infrastructure and Transport specifications.

Electrical infrastructure
As electrical networks grow increasingly complex with smart technologies and public safety demands, infrastructure such as switchboards, conduits, pits, power supplies, CCTV and distribution boards must be resilient and futureproof.

Tonkin delivers practical and compliant designs for all scales of electrical reticulation,
including metering, control systems, UPS backup, and asset protection within built environments.

Lighting systems and controls
Tonkin is involved in pedestrian precincts and road corridors to plazas and feature lighting. Our lighting design systems are both technically sound and visually cohesive. Our experience spans from AS/NZS 1158 public lighting to DMX/Dali lighting controls. Our solutions include layout design, photometric modelling, bracket selection, and smart control systems tailored to user needs.
