About Us

Shirley Consulting Engineers is an investigative, remedial and ground engineering consulting practice that was established on Sydney's North Shore in 1974.

The firm originally focused on geotechnical investigations and slope stability issues, and acquired considerable skills in ground engineering design, landslide control systems and reinforced soil technology.  Later the firm expanded its horizons into the forensic engineering field, and the related expert witness services, reports and evidence in court.

The forensic investigations have included many of the major engineering and mining failures that have occurred over the past 20 years in Australia [including the Thredbo landslide], as well as residential and commercial structure failures.  As such, the firm is now a ‘specialist’ in the forensic investigation / evaluation of failures for a variety of civil, mining & ground engineering structures.

SCE also provides a quality engineering investigation & advisory service that reflects its deep understanding of the causes of slope & ground instability, subsidence [including mine subsidence], ground anchors and earth retaining structures.  SCE also have a comprehensive in-house resource of photographs, maps and specialised technical information on geotechnical & ground engineering that has been built up over the years which is used to assist clients.

The firm acts as a consultant to various insurance groups & loss adjusters, law firms, state and local government bodies, contractors, commercial / industrial groups, legal practices and private individuals.

In 2023, the firm's operations became 'fully electronic' with the professional advice being primarily provided by Andrew Shirley.
