On the evening of February 5 and the early morning hours of February 6, 2023, extreme temperatures led two pipes to burst in the Stewart Biology Building, causing flooding in parts of the North and South Blocks.

When flooding occurs in a building that contains asbestos, there is a chance that water may carry asbestos fibers out of closed walls and ceilings (where they are contained and generally safe) into open areas such as rooms and hallways (where they may later disperse into the air and pose a risk). Therefore, clean-up was conducted with the aim of both remediating the flood damage and removing asbestos that may have been carried by water into open areas. As part of this process, extensive testing also took place in the North and South Blocks.

After cleaning took place, all air tests indicated that the building was safe for use. However, further swipe tests revealed trace amounts of asbestos. Though the air test results would have provided sufficient grounds to re-open the building at that point as per Quebec government and 成人VR视频 standards, we decided to undertake an additional round of cleaning in areas where these trace amounts were found in swipe tests. We recognize that this additional degree of caution delayed the re-opening of the building and understand that these disruptions caused major issues for many of you, with a real and regrettable impact on teaching, research and other vital activities. Nonetheless, these disruptions were unavoidable as we worked to repair the flood damage, clean the affected areas, and keep our community safe.

On the evening of Wednesday, February 22, we received new air test results for the North Block. Like the previous air test results, these indicated that the North Block was indeed safe as per both Quebec government safety standards and 成人VR视频鈥檚 more stringent self-imposed standards. Therefore, we announced that the North Block would reopen.

On the afternoon of Tuesday, February 28, we received additional air test results for the South Block. As with the North Block results, these were in full compliance with Quebec government safety standards and 成人VR视频鈥檚 self-imposed standards and indicated that the South Block was safe. Following this, the South Block reopened as well.

Yes. Air testing was conducted to provincial regulatory specifications in the affected areas of the North and South Blocks. Without exception, each of these tests showed that the air is safe as per Quebec government standards and 成人VR视频鈥檚 own more stringent standards.

The building was in fact locked as of Monday evening, Feb. 6 (except for one door that was inadvertently forgotten and enabled some individuals to enter on Tuesday morning, despite the message and signage indicating that the building was closed). Posters informing people that the building was closed were put up on all perimeter doors of both North and South blocks at the end of day Monday (Feb. 6).听

Between Sunday evening (Feb. 5) and Monday late morning, access to the flooded areas was restricted by security agents (including all of the South block, given the central location of the damages).听听

On Monday morning (Feb. 6), water supply to the entire building was suspended while the source of the flooding in the South block was being investigated. A message asking people to avoid the building was sent at 8 a.m., also informing the community that morning classes had been moved online or cancelled. As individuals continued to enter the building and the water supply had been suspended, the community was informed a few minutes after 11 a.m. that the building was closed.听

In this case, it was assessed that, due to the location of the floods, it was difficult to isolate the areas subject to the flood.听

When events occur that affect business continuity, the Emergency Operations Centre (EOC) is convened. EOC brings in expertise and representatives from all areas of the University. Each situation is different and will have different impacts. EOC is responsible for planning the necessary actions required to limit the impact of an event, starting with the safety of community members.

Beyond emergency management, the team that runs EOC also works on emergency preparedness. This includes developing听mitigation measures aimed at minimizing the impact of听unexpected events听on听University听core听activities.听The lack of access to alternate teaching spaces at the University, for example, is among the things that will be looked at.听Many types of events can occur, so part of the work involves identifying the likely scenarios and applying lessons learned from past events.

Unfortunately, there is no easy way to reschedule a large number of classes that take place in large classrooms within the campus. The University is working on having better swing space for classrooms, but the issue remains for now.

This includes developing听mitigation measures aimed at minimizing the impact of听unexpected events听on听University听core听activities.听The lack of access to alternate teaching spaces at the University, for example, is among the things that will be looked at.

Decisions of this kind are always made based on the information available at the time of the decision. As a guiding principle, if an affected area can easily be identified and isolated, a similar event would typically not lead to a full building closure.听听听

Three types of tests were deployed:

• Bulk sampling: These tests consist听of taking samples of building听materials (e.g. walls or ceiling tiles) to verify whether they contain asbestos. We analyzed the materials that were damaged by the flooding incidents to help听identify the potential risk of asbestos being released by these materials.
• Wipe tests: Also called 鈥渟wipe tests,鈥� these involve wiping horizontal surfaces (desks, floors, etc.) to detect the presence of asbestos fibers and help guide our air-testing efforts. Wipe/swipe tests are not mandated by Quebec government regulators, nor are their findings sufficient to deem an area safe for use. They can, however, be helpful in determining whether asbestos is present in open areas (i.e. in a room, rather than contained in a wall). When wipe tests detect asbestos in open areas, the next step is typically cleaning and air-testing in those areas.
• Air tests: An air test conducted to government specifications, and yielding results that meet provincial and 成人VR视频 safety standards, can lead to the determination that an area is safe for occupants.

Test results for the North and South Blocks are posted below.

The final swipe tests yielded only trace amounts of asbestos almost entirely at the minimum threshold detectable by the testing laboratory, and were followed by an additional round of cleaning as an extra precaution. Since subsequent air tests confirmed that the building is safe as per Quebec government and 成人VR视频 standards, no additional wipe testing is required.

For air tests to pass at 成人VR视频, the results must be under the threshold of 0.01 fibres per cubic centimetre. This is the same threshold dictated by the government after asbestos abatement work to ensure that a space is safe to re-open.听听听

成人VR视频鈥檚 self-imposed threshold, applied as our safety standard across all University buildings, is a maximum of 0.01 fibres per cubic centimeter of air. This is the threshold used to ensure safe occupancy after work done in high-risk conditions due to the presence of asbestos. Outside of this kind of work, the regulatory threshold used in Quebec is 0.1 fibres per cubic centimeter of air. 成人VR视频 prefers to always use the more stringent threshold of 0.01 fibres听in order to ensure the highest possible degree of confidence in the safety of our spaces. Because we all learn, teach, work, study and socialize in the University鈥檚 buildings, it鈥檚 vital that we be 鈥� and feel 鈥� safe in them.

Wipe tests were used to guide our cleaning and further testing. This allowed us to determine areas affected by the flood and potential further contamination.听

Yes. We will continue to conduct regular air tests in the Stewart Biology Building in the coming months. We have identified 24 locations across the eight floors of the building. The results of the air tests will be posted on the EHS website. If any tests results fall short of 成人VR视频鈥檚 standards, the context of that particular result will be evaluated and, if deemed necessary, the areas in question will be closed, cleaned and re-tested.听As we will be doing extensive monitoring of air in the building, we will have more information that should allow us to safely isolate the affected portion of the building without having to close the complex.听

The database is meant as one of the tools in the asbestos management protocols of the University. When any kind of intervention needs to be done (renovation, work) individuals in charge of the operation or its planning first check within the database (I) whether the area in which the intervention will take place is listed in the database and (ii) whether the building itself is noted as containing asbestos. If (I), then corresponding measures for work under asbestos conditions are taken; if (ii) but there is no indication around the specific area of work, local samples may need to be taken prior.听

The updating of the database has suffered from the shortage of staff we experienced in our EHS unit in recent years. Many more reports exist and are archived at EHS than are available in the online database, and we are working on eventually having them all available online. If not available in the database, the reports can be obtained from EHS. Future air test results will be posted on the EHS website.

Note that the asbestos database is housed on the myLab platform, which underwent an upgrade and migration, completed in mid-February 2023.听

Asbestos was used in construction in many structures built in Quebec between 1930 and 1990, according to the . Asbestos is a health concern if the fibers are inhaled, that is, if they are present in the air. 鈥淢aterials that contain asbestos and are in good condition do not release fibers into the air and are generally safe,鈥� according to the government鈥檚 information.

According to the Government of Quebec鈥檚 information about , the 鈥渞isk of someone having health problems associated with exposure to asbestos increases with the amount of asbestos fibers to which the person is exposed and the duration and frequency of the person鈥檚 exposure to asbestos fibers.鈥� It also mentions that 鈥淗ealth problems associated with asbestos are rare in the general population鈥�; they are more common in people who work in 鈥渁sbestos mines,鈥� 鈥渇actories that manufacture parts containing asbestos鈥� and the 鈥渃onstruction and demolition industries.鈥� This is because people in those jobs have a significantly higher chance of being exposed over a longer period of time and to higher concentrations.

A few building users have reported that they were unable to be fit-tested for entry during the closure, because of scarce supplies of PPE. Unfortunately, this is true. Due to industry supply issues and high PPE demand within our community, maintaining surplus inventory has proved challenging since the beginning of the COVID-19 pandemic. As well, PPE expiration dates make it difficult to maintain stockpiles over time. That said, we are redoubling our efforts to locate reliable suppliers around the world, and to build sufficient stock to ensure we are better prepared in the future.

The University鈥檚 Emergency Operations Centre is activated in situations like these. The Centre pulls together key expertise from staff across the 成人VR视频 to deal with situations such as the one at the Stewart Biology Building. Once it is activated, it takes over to deal with the emergency, and that includes communications.

We have heard issues about the communications and announcements. Part of the lessons learned here is the need to strengthen the lists we can use to warn people.

Construction resumed on February 23 and we are at approximately 70% advancement for the last phase of the project, which is the interior fit-out. We should have a better idea of completion date soon. Meanwhile, we are actively planning the allocation of space.

We continue to discuss funding for this project with the government. It is a major project with a cost of more than $150M. The government has authorized us to begin the planning phase (for which we also rely on government funds). The experience and knowledge coming out of the West block project will inform this planning.

The presence of asbestos in a building does not make a building inoperable. There are many buildings at 成人VR视频 that contain asbestos and we have protocols in place to manage incidents that involve asbestos. Incidents such as the Feb. 5-6, 2023, flooding help us identify building areas that may require additional vigilance or systems components that may need closer monitoring. For example, in future extreme temperature events, we can add surveillance in more vulnerable areas. Also, the full renovation of the block does not exclude proceeding with smaller repairs as needed that can help us minimize the risks of such incidents occurring again or limiting their impact if they do occur again.

Renovation of the Stewart Biology Building is very complex. It had to be planned and executed one wing at a time, since it requires that the spaces be emptied and there is not a lot of swing space at 成人VR视频, especially when it comes to accommodating labs. Many factors can have an impact on the duration of a project, starting with:

• Obtaining the necessary funding from the government.
• Labour availability: In the past few years, we have suffered from the unprecedented labour shortage experienced in many sectors, including construction.
• Surge in costs: The construction market has been overheated in the past few years and prices shot up to unexpected levels. As part of the West wing project, we had to completely cancel a call for tenders when the only two bids received were considerably higher than the planned budget. This delayed the project by many months.
• Quality control: We may sometimes face delays caused by work that was not done correctly and has to be redone, or errors or omissions made in the design phase that need to be addressed.
• Governance: If, for some reason, the call for tenders takes longer than expected, this in turn delays the approval by the Board, which can set us back by a couple of months further.
