Underground infrastructure has been a staple of Associated Engineering’s portfolio since 1945, when the firm formed as Davis, Ripley and Associates with offices in Edmonton and Calgary. In 1948, the firm renamed itself to the more inclusive Associated Engineering Services Ltd. With offices across Canada, Associated Engineering is one the largest Canadian-headquartered engineering firms designing trenchless projects across the country. With more than 70 years of service in Canada, the firm was incorporating trenchless into its designs long before trenchless was a term in the construction industry lexicon. Today, Associated Engineering is still a leading engineering consultant firm in Regina, Saskatchewan.
