Red Earth First Nation School Addition

Red Earth First Nation School Addition
Date: 2013

The Red Earth First Nation are situated along the banks of the Carrot River, at a remote location in North East Saskatchewan, North of Provincial Highway #55. Executing the $13-million school renovation and addition project, Dunmac General Contractors subcontracted AGRA Foundations Limited for the foundation works of the building addition. The AGRA team 171 closed-end pipe piles (8"x40' to 16"x60') and 107 driven timber piles (12"x40' to 15"x55'). The soil conditions on-site consisted of soft to firm clay of medium plasticity, and moist to wet into depths of about 7 m, causing seepage and sloughing. Below, the clay was stiff and firm with high plasticity into depths of 15 m.

Solution:

Driven piles were an ideal solution to overcome the sloughing conditions on site. The AGRA crew used a Link-Belt LS108 crawler crane with an H-lead and a drop hammer to install timber and steel piles. The remote location required about two hours of crew travel each day.
