EC&M Limited (ECM) was established as Electrical Construction and Maintenance Australia Pty Ltd. By 2009, the company had become the largest privately-owned electrical & instrumentation (E&I) contractor in Western Australia and a fully diversified national engineering group. Operating throughout Australia and overseas, ECM is a provider of construction, installation, industrial and maintenance services for businesses operating in the resources, energy and infrastructure sectors. It also has a growing emphasis on the emerging renewable energy segment. It has major offices in Canning Vale, WA and Murarrie in Queensland, which are supported by the Kwinana Office & Fabrication Facility located in Western Australia (formerly known as Press Construction Group).
EC&M went into administration in early 2019. In December 2019, EC&M was acquired by GenusPlus.
