Actually the mobile crane is installing the steel bracing system for the north and west walls of the old law office on Dufferin. This bracing system will hold those walls in place while the rest of the house is demolished and the pit is excavated out. Same method was used on the old facade of the Kingsmill building along Dundas St. for the new Fanshawe college building. Activity on the north side of pit should really pickup steam with the HCM foundation company returning to drill the NW side pilings and start removing the soil and house basement. Once that is done we should probably see a 2nd tower crane installed in a strategic location to avoid the current crane and Tricar's condo tower across the street.
