Geotechnical Investigations and Considerations for Successful Trenchless Projects - Sept. 20, 2018


Canadian Construction Association (CCA) Gold Seal Accredited Course 

Good geotechnical information is critical for selecting proper trenchless technology, design, and determining construction risks and costs. This workshop will discuss the geotechnical investigations and requirements for different trenchless construction methods. It will cover industry’s good practice guidelines and standards for preparing geotechnical reports for successful trenchless projects. Case studies will highlight good practices to avoid construction difficulties, project delays and costly construction claims.


Centre for Health & Safety Innovation (CHSI), 5110 Creekbank Rd, Mississauga, ON L4W 0A1
