UPDATE. May 1, 2026: It looks like the work may not begin until Monday, May 4th. It's also been clarified that access through the work area will be preserved for pedestrians for at least the beginning of the work. The article has been edited to reflect this.
Prostar will begin work in the area between the 240 and 244 buildings to remove and replace the membrane. Technically this is considered an emergency repair as the area has the worst leaking in the underground parking. For my purposes I am categorizing it here as part of Phase 2 of the membrane project.
Work will likely begin on May 4th and may last up to a month. Pedestrian access to this area will be cut off at some point, but will be open for at least the initial part of the work. Once access is cut off, you will not be able to come up the stairs from Allen Street to enter the property during construction.
Owners and residents with patios facing the affected area have already been informed.
Below, the shading shows the affected area (click to enlarge).

The work will take place in the area with the pathway that is three pavers wide. The photo below shows the area (patios facing the area will also be affected):
