BAUER Foundations Canada Inc. was contracted in Dec 2019 by OPUS to design, supply and install a shoring system consisting of soldier piles and timber lagging, for the BOW45 medical office building development. The project is located in the community of Wildwood in Southwest Calgary, Alberta.
The temporary shoring system comprised 70 steel soldier piles set into bored holes, 49 tie-back anchors and 1,300 m2 of wood lagging. The total wall perimeter was 163.5m and had a maximum retained height of 7.5m to 8.5m.
BAUER Foundations Canada mobilized a BAUER BG 28 rotary drill rig to site which was used to drill the bored holes for installation of the steel soldier piles. A Klemm anchor drill rig was used to install the tie back anchors to provide horizontal restraint to the shoring system.
Soil conditions on site consisted of gravel and silt for the first 3m underlain by siltstone.
After completion of the soldier pile installation, the excavation proceeded in shallow increments to allow for the installation of wood lagging between the soldier piles.
BAUER Foundations Canada completed the project on time and met all quality specifications.
