HCM was contracted to provide the design and installation of shoring system for a 110 unit building consisting of town homes, studios and condos. This development was located at 1037 Second Avenue N. W. Calgary, Alberta. HCM, in conjunction with RWH Engineering, designed, supplied and installed a tied-back continuous caisson wall.

The shoring was designed for a maximum excavation depth of 10 meters below grade for a total of approximately 18,900 square feet of shoring area. The soil conditions consisted of gravels with the presence of ground water, making the continuous caisson wall the superior solution due to the zero ground loss and minimal water infiltration advantages.

This project had strict timeline requirements and called for the shoring to be completed in 28 days. In order to finish the project on time, HCM had to use double shifts and injection anchors to double the anchor production. The steps taken by HCM were successful and the project was finished within the given deadline.

The site topography presented the challenging task of installing shoring on steep slopes which impeded the accessibility of conventional equipment to the residential lot at the back alley portion of the site. The site was located in the Elboya Park region of SW Calgary. The purpose of the shoring was to protect the adjacent neighbouring property and utilities along the east, west and back sides of the site.

The east and the west sides of the property were shored with a cantilever steel pipe and timber lagging system. The shoring on these sides extended to 11 feet below grade, and approximately 70 feet long for a total area of 1,800 square feet.

The back side of the property presented the greatest challenge as it was along the steepest slope of the site with a designed depth of 15 feet below grade. Due to the site conditions, shotcrete was an ideal shoring solution. The total area of the shotcrete shoring covered 350 square feet.

Due to the residential nature of the site special emphasis was put on the impact of the project to the surrounding area. The disruption to neighbouring properties, along with noise and vibration and existing structures was carefully monitored and managed.

HCM finished the project on schedule completing in two planned stages according to the progress requirements of the general contractor.
