Andrew Huston: Director

Andrew is a Project, Construction and Engineering manager having directly managed over $900m worth of project work with a majority of these being brown-field projects. This experience extends across the mining industry (coal, copper, gold and uranium), power generation (hydro & thermal) as well as LNG experience as a study manager.   

This unique experience and enjoyment of project work has fostered the development of an in-depth understanding of what is required to deliver a successful project,  from the study phase through to commissioning and handover.  Andrew's most recent assignment was as construction manager at a brownfield project at a copper mine in Laos.  A new Scrubbing Facility was installed on schedule, well under budget, a quality installation and with Zero Harm. One reason for the success was the ability to be involved from the feasibility study stage to be able to set up the project correctly to transition into construction and commissioning.

This experience is supported with seven years in maintenance as a workshop supervisor, mechanical engineer and outage manager within the power and mining industries, providing a strong understanding of the operational outcomes a project is required to deliver.   

Andrew's qualifications include:

  • Graduate Diploma Business
  • Bachelor of Mechanical Engineering (1st Class Honours, University medal)
  • Diesel Fitter
