ABSTRACT: A new, fully automated precast concrete pipe plant was constructed in the northwest area of Calgary, Alberta. The initial site investigation identified a deep fill up to 32 m thick. Traditional approaches of deep foundations or replacing the existing uncontrolled fill were initially evaluated as options to address the issue of the deep fill. A more innovative approach using ground improvement and shallow footings was proposed to reduce the cost of foundation construction. This paper provides case history information of the use of dynamic compaction as a successful technique of ground improvement in the Calgary area.

RÉSUMÉ: La construction d'une nouvelle usine de tuyaux de ciment pré-moulés, entièrement automatisée, a été prévue dans la zone nord-ouest de Calgary, Alberta. L'investigation préliminaire du site a permis de localiser un remblai d'une épaisseur de 32 mètres. Deux solutions ont été envisagées pour aborder ce problème: l'approche traditionnelle de construction de fondations profondes ou le remplacement du remblai. Une approche plus innovante, utilisant des techniques d'amélioration du sol associées à la construction de semelles superficielles, a été proposée pour réduire le coût de la construction des fondations. Cet article présente une étude de cas pour lequel l'utilisation de la compaction dynamique a été utilisée comme une technique efficace pour l'amélioration du sol dans la région de Calgary. 1 INTRODUCTION
