A major expansion was carried out at the Consumers’ COOP Refineries Ltd. (CCRL) in Regina in 2011 and 2012. As a part of these works BAUER Foundations Canada Inc. was awarded the contract for installation of CFA piles for the demineralization building. The scope consisted of drilling 24 CFA foundation piles with a diameter of 780mm and 200 with a diameter of 600mm with depths up to 15m.

All works had to be carried out within the area of an operational oil refi nery. Particular attention had to be paid to the very strict safety rules to protect workers in the potentially flammable atmosphere. Among many other site safety requirements, positive shut-off valves for all equipment and blast-proof crew containers had to be utilized.

Due to very short notice provided prior to site mobilization, BAUER Foundations Canada Inc. did not have sufficient time to resource a standalone CFA pump, therefore a 40m boom concrete pump truck was connected to our BAUER BG 28 rig.

Most of the piles were located in confined spaces such as between tanks and piperacks. Some piles had to be installed within 2m of active utilities.

The piles were completed ahead of schedule and the high quality of work was to the satisfaction of our client.
