Deep Foundations for the Ice District towers E and A in Edmonton (Alberta)
Allan Bowers

This project is part of Edmontonís downtown ICE district development which will be Canadaís largest mixed-use sports and entertainment district. The presentation will describe the construction of the foundation piles for the JW Marriot hotel (tower A) and the Stantec tower (tower E) which will be the tallest tower in western Canada with 66 floors. The foundations for the towers consisted of steel reinforced piles with diameters of 1.5m and 1.85m and lengths up to 75m. Construction of the piles occurred inside an 18m deep excavated pit which presented unique challenges in terms of space, heavy lifts and material deliveries. Prior to the installation of the working piles, Oesterberg load tests were performed one of which was tested up to a load of 47MN in order to confirm the design parameters. Quality control testing to confirm the integrity of the installed piles was performed by means of Cross-Hole Sonic logging (CSL) on all piles and additionally with coring for some selected piles.
