The Canadian Society for Civil Engineering (CSCE) presented its Award for Excellence in Innovation in Civil Engineering at the CSCE Annual General Meeting and Conference held June 14-17 in Ottawa, Ontario. The award, sponsored by Canam Group, was bestowed to DIALOG^TM, Lafarge Canada and the University of Calgary for their innovation Ultra-High Performance Concrete in Architectural Cladding.

“The CSCE is very pleased to partner with Canam Group in presenting the Award for Excellence in Innovation in Civil Engineering,” said George Akhras, Chairman of the CSCE Innovation and IT Committee. “This award, created to encourage innovation in all civil engineering disciplines, is bestowed on an individual or group belonging to a Canadian firm or research organization involved in the practice of civil engineering in Canada.” He emphasized that this award is primarily intended to encourage creativity and ingenuity in civil engineering practice.

Summary of the Innovation:
Increased demand for sustainable solutions and ongoing advancements in construction materials technology is allowing Ultra-High Performance Concrete (UHPC) to conquer new frontiers in the construction industry. The Atrium project in Victoria, BC is the first building in North America to have a UHPC façade. This unique project involved close collaboration between: panel designer—DIALOG™, precast manufacturer/UHPC material supplier—Lafarge Canada, and panel testing—Department of Civil Engineering, University of Calgary. A result of this collaboration is the customized design and creation of highly durable, attractive, ultra-thin UHPC cladding panels.

Understanding the characteristics of UHPC—very high compressive strength associated with ductility, flexural behavior and tensile properties, in addition to its superior durability characteristics and flowability/mouldability, made UHPC the logical choice for use in the seven-storey building’s façade. These characteristics made it possible to design/produce aesthetic panels as thin as 17 mm with irregular, complex shapes and integral texturing. A total of 690 flat and curved panels were utilized.

Stone or granite panels would have been much thicker and heavier than UHPC panels. In addition, introducing surface texture on such materials is impractical, labor intensive and extremely costly. Furthermore, since the project is located in a high rated seismic zone, the heavier panels penalize such products. Metal panels could have been used to produce curved shapes but are typically not suitable for forming tight radial curves, and cannot have irregular textured face similar to that produced for the Atrium.

For the Atrium project, one of the goals was to achieve sustainable construction with a balance between initial environmental impact and the life cycle. Considering that concrete is the most common manmade building material and one of the largest sources of industrial emissions, minimizing its quantities and improving its durability led to use of UHPC for this project, and is a step towards achieving sustainable solutions.

Use of UHPC is expected to increase in popularity in the coming years as more engineers, architects, and building officials become aware of the material’s potential and as guidelines for its design and use become available and adopted in the North American Standards.

The Canadian Society for Civil Engineering (CSCE) presented its Award for Excellence in Innovation in Civil Engineering at the CSCE Annual General Meeting and Conference held June 9-12 in Winnipeg, Manitoba. The award, sponsored by Canam Group, was bestowed on the following group of four British Columbia organizations: the Association of Professional Engineers and Geoscientists of British Columbia; the Ministry of Education of British Columbia; the Seismic Peer Review Committee; and the Earthquake Engineering Research Facility of the Department of Civil Engineering of the University of British Columbia for their innovative Guidelines for Performance-Based Seismic Assessments and Retrofits of Low-Rise British Columbia School Buildings.

“The CSCE is very pleased to partner with Canam Group in presenting the Award for Excellence in Innovation in Civil Engineering,” said George Akhras, Chairman of the CSCE Innovation and IT Committee. “This award, created to encourage innovation in all civil engineering disciplines, is bestowed on an individual or group belonging to a Canadian firm or research organization involved in the practice of civil engineering in Canada.” He emphasized that this award is primarily intended to encourage creativity and ingenuity in civil engineering practice.

In November 2004, the premier of British Columbia announced a $1.5-billion seismic mitigation program for schools in the province. The B.C. Ministry of Education requested the assistance of the Association of Professional Engineers and Geoscientists of British Columbia (APEGBC), in collaboration with the University of British Columbia (UCB), to develop standardized seismic retrofit tools for the implementation of the seismic mitigation program.

With the support of the Ministry of Education, the APEGBC has delivered a performance-based risk assessment tool and a set of retrofit design guidelines for the seismic upgrading of existing school buildings in the province. These seismic retrofit tools have been peer-reviewed by leading provincial and international professional engineers and offer low-cost public safety solutions that can be used by local practitioners.

This innovative applied research project incorporates a performance-based probabilistic methodology, the seismic hazards associated with three types of earthquakes (crustal, sub-crustal and subduction) likely to occur in the province, and site response analysis to determine soil amplification effects. An important outcome of this project is the creation of a large electronic database of analysis results that can be readily accessed by all registered practitioners.

The technical development is a collaborative initiative by the APEGBC Seismic Peer Review Committee, a panel of highly experienced local professional engineers, and the Department of Civil Engineering of the University of British Columbia.

This groundbreaking work involved a unique collaboration between the B.C. Government (Ministry of Education), engineering practitioners (SPRC), academia (UBC) and the provincial engineering regulatory body (APEGBC). Their accomplishments have been recognized both nationally and internationally by leaders in this field. This innovative approach is being used to address a significant public safety concern in British Columbia, while making an important contribution to the international engineering community towards reducing injury and loss of life due to earthquakes.
