Welcome to ERDS

Electrical Reticulation Design Services Pty Ltd (ERDS) traces its beginnings back to 1997 when it began life as a home-based partnership with its founder, Merv Roseler, as Principal. Since its incorporation as a propriety company in 1999,  ERDS has grown to now employ over 25 staff in a range of specialist positions including Lighting Designers, Traffic Signal and ITS Designers, Electrical System Designers, Electrical Engineers, CAD Drafters and Project Managers.

ERDS provides services to public organisations such as DTMR, Energex and Ergon Energy, as well as a broad range of varying sized private firms. The specialist design and consultancy services offered by ERDS are provided from our Murarrie and Gold Coast offices. 

Many things have changed over the two decades we’ve been in business, but there has always been one constant; the ERDS service offering, which is based on delivering innovative electrical design solutions that meet our Clients’ needs in a timely and cost-effective manner, to uncompromisingly high standards.

Highly experienced, we approach all of our projects in a systematic and efficient manner with our focus on the quality of service never wavering, a fact that’s illustrated by ERDS gaining recognition as an ‘A’ rated consultant with both Energex and Ergon, two of Australia’s largest electrical utilities.

In March 2025 ERDS was acquired by Roesner and Hamilton. Roesner and Hamilton is a leading provider of civil and electrical consulting engineering services, renowned for its commitment to quality, innovation, and customer satisfaction. The merger results in a team of over 50 skilled professionals across offices in Brisbane and the Gold Coast.
