I'm sure you've already covered this, but what is the purpose of these moats around the floor/foundation?

 

For the crocodiles, of course!

 

we're replacing the foundations in those areas

 

Lol Because crocs are an issue in Western Canada . They're a total pita. On my fifth dog this year alone.

 

Any particular reason why or you're just a glutton for punishment? I know I'd be really hesitant to engage in
such shenanigans during ski season.

 

we're doing a full gut renovation on this house , some of the foundations were inadequate for the new seismic requirements of the shearwalls we are adding and some had settled and cracked from being on fill , we have excavated to undisturbed bearing that satisfies the geotechnical and structural engineers

 

That's awesome; Is seismic a big deal where you live?

 

The area I live in has the highest seismic potential with respect to lateral restraint in the building code in Canada

 

My dad lives in West Van, but lived in Qualicum. He grew up in Oak Bay and Denman Island.

 

yeah Vancouver Island / Gulf Islands and part of the lower mainland has the highest spectral acceleration values in Canada

 

seismic requirements are part of the BC Building code , there are 2 solutions , either your building complies with provisions in Part 9 of the code (residential) with respect to minimum sizes of brace wall panels within brace wall bands or if not it needs to have a structural engineer design the building for lateral restraint with respect to the spectral acceleration values given for each jurisdiction

 

Is lateral or transverse acceleration more of a concern at the coast?

 

No idea , I'm the builder not the engineer

 

Thank you for all the info. As an engineer I'm just curious.

 

if it fits, it sits...

 

CMM or similar machine?

 

Correct. Zeis. Getting First Article Inspection done.
