Masonry is a 5000-year-old building technology proven to perform well in all types of built environments, given its inherent resistance to fire, insects, and moisture degradation. However, the expectations for buildings have grown from simply providing shelter to maximizing use of renewable, recycled, and recyclable materials, as well as space, energy, sound, and light.
Whenever a city wins a bid for a major international sporting event, there is a surge in construction activity—some to complete projects previously approved (e.g. infrastructure improvements) and some to construct new venues specific to the needs of the games.
“Look out everyone—the inspector is coming!” Whether it is an owner’s representative, a construction manager, or a ministry official, there always seems to be a heightened sense of duty and care when inspectors are on the job. It is natural for everyone to step up his or her efforts to do what is right when their work is being inspected.
Anecdotal evidence suggests cracking of concrete structures and components appears to be on the rise, often resulting in conflict between involved parties.

The International Scientific Advisory Committee (ISAC) is hosting the first Interactive Symposium on Ultra-high-performance Concrete (UHPC), which includes a student competition with a finalist team from the University of Ottawa.
Major infrastructure that affects the lives of tens of thousands on a daily basis must last for its expected life (at the very least)—otherwise, a ripple effect is caused to government budgets, negatively affecting each citizen in some capacity.
A suite of e-books, collecting some of the best and most popular Construction Canada articles, is now available free of charge. The anthologies bring together diverse stories on five topics—acoustics, sustainability, concrete, thermal insulation, and wood design—in full-colour pdfs for you to download and enjoy online or off.
Producing a good quality polished concrete floor may appear to be a relatively simple task.1 Certainly, when conditions and circumstances are favourable during the various phases of construction, highly durable, attractive surfaces and finishes can be achieved that require very little maintenance.
Many Canadian bridges have been deteriorating for decades or repaired and re-repaired throughout the years. How do the responsible authorities prioritize which concrete infrastructure needs to be fixed or strengthened and which needs to be outright replaced?
