TTC Patten Building

HC Matcon was retained to install micropile foundation for TTC Patten Building on 835 Davenport Road, Toronto. The building was originally designed for storage of paper tickets and when TTC transitioned to using tokens the increased loading caused settlement and structural issues which required strengthening of its foundations. 

The project consisted of drilling and installing 90 micropiles to a depth of 15M.  Working conditions presented an issue as drilling was restricted in a basement of an existing building where headroom was 3.5 meters high. HCM mobilized the Klemm low headroom drill rig in order to complete the project with productions to meet the strict deadlines required from TTC. 

The project was completed in a timely fashion and on budget. HC Matcon is well equipped to deal with difficult conditions presented on any project and are experts in micropile installations.
