Hydraulic Consulting Engineers

Maclean & Lawrence Pty Ltd, an Adra Group Company, was formed more than 30 years ago and has established a niche operation within the Western Australian construction industry as Consulting Engineers.

With a focus on Hydraulic Services, Maclean & Lawrence Pty Ltd has been involved with a diverse range of projects across Western Australia – from Broome to Esperance, Kalgoorlie to the Perth metropolitan area.​

Extensive experience in projects including hospitals, hotels, schools & universities, aged care facilities and industrial subdivisions, water mains, sewer extension and treatment systems and energy, including solar designs.

The company was an early adopter of CAD capabilities, with our first foray into the field made during the early 1980s. We have continued to invest in IT resources to remain equipped to design to the latest standards.

The company is proud to have joined the Adra Group of companies in 2021 and is looking forward to the support and growth opportunities that this will result in.
