Seismic standards that are serious for heritage buildings? star-news.press/wp

What do Saint-Denis do in Rue Saint-Denis, in Boulevard René-Lévesque, not even Hôtel-dieu? All of these Montreal heritage buildings are empty or lie, Quebec has a housing crisis.

According to various experts consulted by Radio-Canada, in 2005, standard resistance to the régie du Bâtime du Québec, which is prescribed by the National Research Council of Canada is responsible for the cost explosion.

One of the last buildings to be added to the long list of empty buildings is the former parent of the Sainte-Anne sister, in the Lachine district. The main building, built in 1906, is in perfect condition. Roof, windows and doors have changed again in recent years. The sisters still lived two years ago.

The Mayor of the Maja Vadanovic Lachine district finds the meat quickly. It has not been the case, because the cost of innovative seismic standards is $ 14 million, which increases the full cost for recoverseing.

There were four large promoters who wanted to work with excellent community projects. But one of them could not unlock everything, seismic standards, means that $ 14 million should be placed. Wooden floors must be scratched, placed beam concrete. Titanic is a job. You put 14 million, and you still didn’t start preparing the job.

It is only necessary only when the change in the use of building seismic buildings. Frequent example: Convent that becomes a building with housing or condoms. However, a building building that would renew would not be renewed that no seismic standard would be subjected to. Another example is the renovated church, but a place of worship remains not to move to standards. It must be a church that becomes a library.

That’s Maja Vadanovic said it’s something random, as well as arbitrary, in seismic standards. It provides an example of the newly renovated Montreal Town Hall. Since the building has not changed, there is no renewal of seismic standards.

The mayor of Lachine asks the government of Quebec, if these standards are temporary, while the housing crisis is solved. Right now, hundreds of buildings are strong, which are correct and buying cities Containers People on the street to take home. The absurd is there. We put too many regulations. We want to want too much, prevent you from going forward.

A familiar problem

The Assistant Director of Heritage Politicians in Montrealon, Taïka Baillageon says that it has been an important brake to convert heritage buildings.

The real obstacle ends with money. The problem of placing seismic rule is that it is so expensive. It is complex and expensive.

The case of Saint-Anne sister’s parents are interesting, according to its seismic standards to know the figures: $ 40 million from $ 40 million to return the building again. An entrepreneur could not embark on an adventure, with full knowledge of events.

However, it is often evaluating the cost of renewal of seismic standards. The founder of the Evoq architecture company, Julia Grossovitz, provides an example of renewing fire safety standards, forces the implementation of automatic vessels. The price of the square meter is known and can be larger if the heritage ceilings with moldings and decorations.

However, in the case of seismic standards, it is necessary to learn the costs of the building structure. Therefore, due to a high impact on budgets, it has been a major impact on budgets.

Julia Grossovitz would like to Rbq Start a center of excellence in standard subject. Like a variety of experts, it is important to start questioning the importance of certain standards. Is the restored heritage living more dangerous than living elsewhere?

It is an important question and trying to respond to McGill Daniele Malomo’s Structural Engineering Professor. In the Faculty of Engineering laboratory, he simulated earthquakes in whole sections of the walls from Montreal heritage buildings.

The first step, says, that cover the level of resistance to old bricks or also limestone waste used for foundations. What is the compression load that the famous gray gray stone can bear? He asks. In Europe, it adds, known to the answers, because research on the resistance of ancient materials, but not here.

His students also experience different materials that may also be used to achieve equivalences to achieve the goal of resistance. For example, a plastic wire network could be placed in the brick, then hidden under a plaster to prevent the fall of a wall of earthquake.

In terms of strengthening innovation materials, it could be used to achieve equivalences Rbq. Facilitate the data collected on their part, reducing rules or fitting standards, without jeopardizing public security, without various experts support.

An important project of the standards

Launch of excellent reflection on the topic of codes and standards is the organization of Montreal in its 50th anniversary.

We campaign to treat it differently than new. And today’s standards are lack of subtlety.

The organization has placed on the table on the subject, and they want to gather construction industry players and professional orders to unlock this file while the Quebec lives a housing crisis.

Academic environment should also be used because it is focused on new training, and not already exists. However, most of the buildings that will live in 50 years are built, Taïka Baillageon said Montreal. So the development of the coming, so in Europe, will be reducing buildings and restorations.

At the moment, McGill University emphasizes Daniele Malomo, about 2% of universities relates to existing buildings. It’s not enough, he said. Engineers need to know work. Daniele Malomo believes that ideology of the building Idiah is changing North American ideology as a result of climate change. Most carbon buildings are already built, it remembers it.

Another solution would be to create a public record of the equivalence measures in the past, the régie du Québec, Bible species of solutionsHe said laughter about the architect Julia Gersovitz. Engineers can easily access access Rbq It has already been accepted as a trade to achieve the seismic level of resistance to the restored heritage buildings.

Ron Rayside, the architect of Labossière Rayide says, is already preparing such registration, information he has not denied Rbq. A Rbq The best way to share the necessary information for developers today isemphasizes the right by email.

Is the standard update in the table too? McGill University Daniele Malomo believes that he will arrive in five years. There Rbq It also says Collaboration in the work of the Canadian National Research Council 10. Part (National Building Code) applies to the transformed buildings.
