Our History

Douglas Partners’ origins began in the early 1960s when the late Don Douglas established and developed the geotechnical engineering and testing services of Frankipile Australia Ltd (a leading piling contractor) under the name ‘Ground Test.’ D.J. Douglas & Partners (now Douglas Partners) was formed as a consultancy in 1983 following a friendly management buyout of these services.
