The Wedge
Scope of Work
WGC’s involvement in The Wedge project spanned multiple scopes of work, including excavation, shoring, and structural shotcrete. The excavation process, which began in 2020 and lasted approximately 12 months, required urban blasting to manage the site’s challenging conditions, such as excessive groundwater and soft marine blue clay. H piles were used in the shoring system to achieve the necessary excavation depth and maximize underground parking. Following the completion of the shoring process, WGC transitioned to structural shotcrete, utilizing this innovative method for walls and columns, which was a departure from traditional forming methods. Notably, WGC is the only NorLand business unit specializing in structural shotcrete, showcasing its unique expertise in this field.
Challenges & Solutions
With the Wedge Building being located in the heart of Victoria, there are many logistical challenges to overcome, one of which is often the lack of site access. Due to the excavation depth, no site entrance road was available, requiring all materials to be craned in and out of the site. Fortunately, M.R. Cranes provided excellent assistance in this challenge. Another challenge involved in the downtown setting is safe blasting procedures, WGC excels at our guarding and covering procedures to always ensure public and worker safety. A continuing challenge in the downtown Victoria region is the presence of soft marine clay, due to the proximity to the ocean and depth of excavation much of this material and groundwater was encountered, creating less than ideal working conditions but as usual, the workers endured and completed this project on time once again.
Spencer Block
Scope of work
This Project consisted of multiple scopes of work for Western Grater including blasting, shotcrete shoring, and tie-back anchors. The shotcrete shoring consists of welded wire mesh and rebar to reinforce the shotcrete creating a stable vertical wall allowing developers to maximize land utilization. Tie-back anchors are drilled and grouted to further support the shotcrete wall system. Western Grater utilizes a hollow anchor bar system which greatly improves efficiency over traditional drilling methods.
Blasting works occurred over a 3-4 month period with a total rock volume of over 8900 cubic meters. Due to the extremely close proximity of the neighbouring heritage building, a “line drilling” method was used to ensure an accurate rock break at desired property line.
Challenges
As with most blasting operations in urban settings, much care must be taken to ensure the safety of all other workers and the general public, as well as the presence of older structures from the early 20th century that the city of Victoria is famous for. On the Spencer Block project there is an adjacent brick building built in 1908 by Sam Kee Laundry, the utmost care was taken to ensure no damage was sustained and the impact to the residents was kept to a minimum. Engineers are also involved in the monitoring of neighbouring structures to ensure all excavation perimeters remain stable and safe.
Another major challenge on this project was the local ground conditions. Due to poor environmental practices in the early 20th century, large areas of the job site contained contaminated soil at depth. The presence of this contamination creates challenges for all contractors involved, such as removal of contamination, which comes with great cost to the client and delineation of materials for the excavation contractor. These conditions also create some hurdles for WGC as the ground conditions were not conducive to bonding anchors to soils. WGC employed the use of a “grout Swivel” which allows us to drill anchors in with continuous grout flow throughout the drilling process as opposed to the traditional method of drilling with air and grouting post installation. The use of this method provided great success upon its application.
