Arnold

What Arnold does

Arnold Electrical and Data Installations (AEDI), trading as Arnold, is a Queensland-based, family-owned electrical contracting and instrumentation company founded in 1974 by Bob and Pat Arnold. The business operates from Salisbury, Brisbane and employs more than 120 staff across project sites spanning South East Queensland, Far North Queensland, the Northern Territory, and Tasmania. Its core offering is end-to-end Electrical and Instrumentation (E&I) project delivery for mining and resources, energy and utilities, commercial buildings, and port and maritime clients, encompassing design, installation, commissioning, switchboard manufacturing, and 24/7 service and programmed maintenance.

The company's underlying technology centres on industrial electrical and instrumentation systems, including PLC and automation control, hazardous area upgrades, substation installations, and an in-house switchboard manufacturing capability (Arnold Switchboards) producing modular low and medium voltage switchboards up to 6000A with AS61439 type-tested compliance, ACB retrofitting, and thermal imaging diagnostics. Underlying systems are conventional industrial automation rather than software-defined or AI-driven platforms.

Arnold's revenue model combines project-based E&I construction contracts (one-time, milestone or completion-based recognition), recurring service and maintenance agreements (multi-year, subscription-like), and hardware sales from switchboard manufacturing. Pricing is quote-based per project rather than published. Go-to-market is enterprise field sales targeting blue-chip resource and infrastructure operators (Rio Tinto, AGL, Sedgman, QCoal, Origin Energy, South32, Aurizon) and major EPC contractors (John Holland, Watpac, UGL, Ventia), supplemented by referral networks, industry events, and SEO. Customer segments are dominated by Queensland mining and resources, with secondary exposure to energy utilities, commercial construction, ports, and government facilities.
