Until December 2022, I'd never heard of a parkade under construction in Langley City having a cave-in or partial cave-in during construction. In December 2022 and August 2024, the construction shoring at two different sites failed.
As I posted in November, Langley City implemented a practice of having independent reviews of the geotechnical design for underground parkades. Last night, Langley City Council adopted a new "CO-87 - Excavation and Shoring Policy."
This policy makes the new practice of having an independent review of geotechnical design a requirement for all proposed excavations with 3 metres or greater depth. It also reserves the right for the City to request an independent review for any excavations.
While this might seem like the City is adding red tape, the safety of our community and workers is paramount. This policy will help improve underground parkades' safety and other underground construction.
