Overcoming Poorly Engineered Fill

This project solved a very difficult problem for Buttcon and Walmart Canada, with the new footings settling on a poorly done engineered fill.

  • The previous winter had frozen some of the fill, and footing settlements of up to 3 inches were on-going as the steel was erected.
  • HC Matcon mobilized a Design Build solution utilizing 60 Ft. long micro piles, with special connections to the already designed footings and piers. Sacrificial steel design was used to provide low cost micro piles.
  • HC Matcon worked 7 days per week for 3 weeks to install 192 piles.

The Walmart store opened on schedule and was a technical success. HC Matcon is innovative when problems occur, working with owners and General Contractors to find the most economical solution.

This 3.5 Million dollar contract involved HC Matcon providing a full excavation, a 16,000 Sq. Ft. shoring and large diameter caisson package for this project. Challenges included the support of historical facades, tight working room, land locked site location and staged demolition. The site required all 4000 Dump Truck loads to be removed through a narrow laneway. HCM demolished a 14 Ft. brick service tunnel, while maintaining a 6 inch live steam line, through piled supports, eventually digging under the live line to maintain schedule. The combined shoring and excavation package was well suited to this project requirement as tight co operation between the excavator and shoring contractor was critical. HC Matcon maintained excavators on site during the full project duration which allowed for many advantages to Ellis Don and the owner.
