Malcolm Stapleton

Principal - Geotechnical and Environmental Engineering

Malcolm is at the top of his field in environmental and geotechnical engineering at Babbage. His work focuses on making projects work with the sites they are to be built on, and inevitably – given the industrial past of New Zealand cities, especially Auckland – dealing with the environmental damage left by previous generations of occupants.

Malcolm heads the Babbage geoenvironmental team, which includes geotechnical engineers and engineering geologists, our geotechnical laboratory, the environmental group, the Bioresearches group, and a team working to address local body and government planning controls. His work in the field has seen him made a Fellow of the Institution of Professional Engineers New Zealand.

Malcolm earned his degree at the University of Canterbury in 1978 and he worked for Babbage from 1981-89 before a four-year spell in England. He returned to Babbage in 1993.

His geotechnical work includes the relationship between materials in a construction environment, resolving design requirements that conflict with the site conditions, geotechnical design and construction support for difficult sites, and project-managing large-scale infrastructure projects.

He is also called on to act as an expert witness and as a peer reviewer.

Key projects include:

  • Whitford Landfill redevelopment
  • LPG pipeline into Christchurch
  • Major dairy projects for Fonterra, Synlait and other dairy companies
  • Upper Harbour Highway services, Auckland
  • Pikes Point East redevelopment, Manukau
  • Jubilee Line extension as senior geotechnical engineer
