@realestatedude0 In reality, groundwater is a difficult to manage. Even well designed systems with redundancy can have issues. In any case, best to have an engineer complete an assessment, ideally someone with knowledge of this design.
@realestatedude0 In theory, the groundwater infiltrates through the native soils, meets the membrane, and travels down the membrane to the base of wall where it is collected in a sub-slab drainage system and is typically pumped to a storm drain connection.
Public policy idea: require colleges to demonstrate where new students will live, as a condition of expanding their enrolment. If there is an existing housing shortage where they are located, they must build new residences before expanding enrolment. Colleges need to take responsibility.
@sdcavens @TalktoARYZE The change shouldn’t be viewed as more conservative, rather it’s about getting closer to a true earthquake response. Variations by period and amplification for ground conditions will be better modelled from this code revision. Mexico City is a case study for when we miss the mark
@sdcavens @TalktoARYZE Can’t point the fingers at the regulators on this one. We should be pointing it at the seismologists 👈. And they would will point us to their studies on the activity of the Leach River fault under Victoria, and the increased shaking expected from the Cascadia Subduction Zone.
@sdcavens @TalktoARYZE Not a primer but the 2020 NBCC is out and can be reviewed. The 2023 BCBC will adopt most of the NBCC. I wouldn’t suggest reading the whole code for changes. Their are a few sources that discuss the key changes: https://t.co/pEmG9EUfps
