The City of Edmonton is one of the Premier Municipalities in North America for its use inInnovative Trenchless Technologies through the expertise of its in-house construction force. The intent ofthe presentation is to showcase the historical advancement of these technologies as adopted by the Cityof Edmonton since the early 1900’s. Edmonton hosts an intensive network of well planned and laid outstorm, sanitary and sewer systems that have been built over the last century through innovative tunnelling& trenchless technologies. With the advancement in technologies, Design and Construction Section(D&C) with the Asset Management and Public Works (AMPW) division of the City of Edmonton (COE)has become the pioneer in the construction of underground infrastructure, primarily sewer and water linesin the City of Edmonton. This presentation will provide an insight into the history of trenchless practices(including micro-tunnelling, pipe jacking, pipe bursting, case boring, auger boring, pit and cores, relining,Tunnelling (Hand & TBM) etc.) within the Edmonton region. The presentation will also look into theevolution from the traditional practices to the new practices involving new equipment, research, riskmanagement and mitigation based on simulation studies. Also presented will be the good practices (keyelements for success) that have been adopted in the trenchless field. All the proposed trenchlessmethods will be cited by effective case studies.
