A note from a source close to the Tour Champlain Est building sought to reassure residents concerned about the stability of their building following the collapse of the south tower on June 24.
The note states that a construction company “added shoring to the post that had concrete chipping” in the building’s garage that day, noting that the post “showed [spalling] after CTS [Champlain Towers South] collapsed.”
For reference, the Tour Champlain East (built in 1994) is located between the partially collapsed Tour Champlain Sud (built in 1981) and its sister building, the Tour Champlain North (built in 1982).
Concrete chipping is the breaking or chipping of a concrete surface, which can expose what is underneath. This often happens when the steel reinforcement under the concrete begins to rust.
The note says that although seven different engineers have assured the board that the building “is safe and in good repair”, the pole should be repaired “immediately to alleviate any doubts anyone may have.” The repair must be approved by the city, the memo said, but the board has requested that the approval process be expedited.
In addition to shoring up this particular pillar in the garage, the memo explained that a structural company had added 13 sensors to monitor any movement in the building.
“They use precise laser readings to determine the precise location of each post, then monitor that target to determine if there is movement. We have been told that this activity is more than what we need to do, but again with great caution we will implement this monitoring program, ”the memo reads.
More details: The note says engineers will return in two weeks to see if there has been any movement in the building.
The memo says the board “will continue to do what is necessary to keep our employees and buildings safe. This is our top priority. Much has been said about the 40-year certification program. Many buildings wait up to 40 years for their maintenance. This is not our approach. We will continue to do the maintenance as we experience it. “
