Communities are often worried about odours emanating from wastewater treatment plants in their backyards, but standards for establishing reasonable odour levels are only just being developed in western Canada.
After a landslide fell on a CN rail line in the steep mountains of B.C., Klohn Crippen Berger was asked to analyze the risks of potential further rock falls and design new protective structures for the track.
From the March-April print edition, page 4 Worldwide 5.5 million people die every year from air pollution. So said researchers at an international science conference held in Vancouver in February. Over half of these deaths occur in the two countries…
Editorial “Comment” from the January-February 2016 print edition, page 4. Hundreds of people came out on a cold night in January to hear plans for changing the Gardiner Expressway in downtown Toronto (see p. 8). It was mostly the grey-hair…
The Copeland Transformer station in downtown Toronto is only the second station in Canada to be built underground. Adding to the project’s complexity, it is being constructed on the site of a historic railway Roundhouse.

The new CAN/ULC-S1001 standard sets out the testing required to ensure that fire protection and
life safety systems work in concert. It will be included in the new version of the National Building Code.
From the December 2015 print edition, p. 10 Near the Ville-Marie Expressway in downtown Montreal, a gigantic construction project is transforming the landscape. The $1.9-billion Centre Hospitalier de l’Université de Montréal (CHUM) is one of the most ambitious urban integration…

Legionella bacteria can be very persistent in building HVAC and water systems, as recent tragedies have shown. In order to avoid such problems, designers need to consider not just a system’s functionality, but also how it can be maintained.

“We were totally amazed by this project. The engineers were able to put an 11-storey tower on a “tabletop” above two heritage buildings and develop special frame systems to take the loads. The huge joints a metre thick are unique and very difficult to cast — completely innovative.” – Jury
“At this remote dam project in Northern B.C. the engineers used innovative and sustainable techniques, such as carefully
protecting the fish habitat downstream with a creative use of turbines to quickly offload the power when necessary. The project involved First Nations and produces 195 MW of clean energy with minimal impact on their ancestral lands.” – Jury
“This was an outstanding project. It was remarkable that the engineers came up with an alternative design that didn’t require the U.S. crossing to close. They used the existing piers and slid the new bridge onto them. We thought it was really innovative, creative and courageous. We gave it the Ambassador award for international work. The ultimate beneficiaries were the people who live in the area.” – Jury
“This project is a combination of dramatic architecture with a complicated structural design to accommodate it. We gave it the special award for “social, economic and cultural benefits to the community.” The library serves as an important focal point that attracts people to Halifax. It also enhances the urban site.” – Jury

“This is a tremendous effort on the company’s part to reach out to their neighbourhoods and the wider world to show the value of engineering and to encourage others to take up engineering as a career. It’s not about the money, it’s about the time. It’s making the effort. That’s a big deal.”– Jury
“The tight urban site for this sports research and recreation complex necessitated a top-down built structure, in which
the lower floors were suspended from a large truss. We admired this unusual arrangement which required complex detailing to deal with load deflections in the truss and movement in the lower levels.” – Jury
