Two attempts had been made by others to build two high-rise condo towers on the site of the former Gaslight Square retail strip at 10th Ave and 4th Street SW, Calgary, Alberta. Centron, a developer, decided to buy it and changed the concept to a single building, mixed-use office retail development. The site was already excavated and seven levels of underground parking completed so a considerable amount of structural redesign was necessary; which includes the upgrade on the existing foundation system.

Designed by RWH Engineering, 80 micropiles are installed 20 to 30 feet below the existing footing to support the additional load. As the installation was undertaken in a 7th floor underground parkade, HCM had to deal with limited access and low overhead clearance. Man-portable drilling equipment was used to compile with these limitations.

Despite the challenges, the project went well with HCM scope of work being completed on schedule. The pile capacity is confirmed by one verification test and five proof tests.

Siemens Energy Blade Plant – Phase 2

HC Matcon’s project at the Siemens Energy Blade Plant consisted of the design, supply & installation of 70 helical piers within the existing plant location in Tillsonburg, ON.

As the project was located in an existing, active manufacturing facility, extra care had to be taken on the part of HC Matcon to work within the confines of the building space, which included tight egress for our equipment and limited head room clearance (20′+/-).

Safety is always a number one priority, but additional attention had to be paid as the work was being completed within an active plant with live personnel maintaining scheduled productions.

Some unforeseen obstructions were encountered during helical installation, but with quick decision making and our crews efficiency, HC Matcon was able to complete the project on time and on budget.

Cobourg Railway Station

Cobourg Railway Station

On this project, HCM, in conjunction with its in-house engineering company, RWH Engineering Inc. (RWH), was able to offer the owner one source for the design, supply, and installation of a complete temporary shoring system and precision monitoring services. 

RWH produced an efficient design that conformed to AREMA railway standards and resulted in savings to the owner, in comparison to the original tendered drawings. The RWH design included a double pile and lagging system with 17.5 meter long tiebacks, required due to the soft soils. In addition, HCM installed 275 mm diameter permanent micropiles at the base of the shoring. The micropiles extended through 12 meters of soil and were founded 5 meters into bedrock to provide the required capacity. 

The general contractor benefited from working with a single source that could take responsibility for all aspects of the shoring and deep foundations work – guaranteeing quality and reducing costs.

144 Park Street

144 Park Street

During the bidding process, HCM proposed an innovative design-build shoring solution for the 144 Park Street project, a 19 storey condominium in the downtown core of Waterloo. HCM was retained by Mady Developments to design, supply, and install a complete 9,500 SF bypass shotcrete shoring system.

RWH Engineering Inc. (RWH), an HC Group company, took on the design and monitoring responsibility for the project. The design consisted of a tied-back bypass shotcrete shoring system to a depth of approximately 5 meters. Bypass shotcrete is a unique solution developed by HCM which combines the benefits of shotcrete with a traditional piling system.

HCM’s design-build approach allows for a single source of responsibility. The HCM/RWH integrated working relationship facilitates quick response to design changes and site issues that may occur, ultimately minimizing potential delays and helping to maintain project milestones.

London Mental Health – Structural Shotcrete

HC Matcon completed a 1,650ft2 structural shotcrete wall in just two days of shooting concrete. The wall had a depth of 0.450m thickness and was (on average) 10m in height.

The first day, Matcon placed a scratch coat at 0.400m thick, and then a surface coat at .050m thick on the second day. Since no form work was used, there was no need for stripping and finishing the wall.

This was the first structural shotcrete wall for both HC Matcon and EllisDon Construction.

This project, located on Fourth Street in the downtown core of Calgary, consisted of a tied-back continuous caisson wall.  The caisson wall provided zero ground loss and minimal water infiltration, an important feature in the high density area of downtown.  HCM was able to call upon experience from similar successful past projects, such as the installation of a tied-back continuous caisson wall for the new Mustard Seed Building on Tenth Avenue and Centre Street S.E., to ensure a successful project.

The system was designed for a maximum excavation of approximately 8.5 meters below grade at the north portion of the site and 10 meters below grade at the south portion of the site.  This resulted in an approximate total area of 13,100 square feet of shoring required.

This project is another example of HCM’s ability to work with a General Contractor to execute a successful shoring project with a tight schedule and budget.

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.

Mapleview Drive

Mapleview Drive

The expansion of Mapleview Drive in Barrie required track protection for an existing railway overpass. HCM was retained to install a strutted piles and lagging shoring system. RWH Engineering Inc. (RWH), an HCM Group company, engaged the design responsibility for the project, resulting in significant improvements to the tendered drawings. HCM and RWH redesigned the shoring system to better suit excavation and bridge footing construction. The redesign revised the center pier shoring system from a boxed in strutted system to a tieback shoring system. This allowed better access for shoring installation, excavation, and forming.

Due to site conditions and steep slopes, HCM coordinated all drilling platforms with the GC which optimized shoring and excavation activities and maintained the project schedule. Coordination with the GC for the temporary bridge placement was paramount as track removal and temporary bridge and track installation had to occur in a time period of four days.
