After 20 years as successful survey businesses respectively, in December 2010 Gary Edwards & Associates and Turner Surveying merged to form SDG. With a shared business philosophy of building trusted professional relationships and providing industry leading service, SDG quickly grew to become one of Sydney’s largest and most respected land surveying companies.   

In March 2012, SDG acquired the Pittwater based practice of Souter & Associates. This practice was Sydney’s leading boutique consultancy specialising in Waterfront titling surveys and advice.
