Original developer stopped paying the contractors though I don't know who the GC was. Current owner who acquired it wants to sell it now so needs to warrant that it isn't just a teardown. From what is visible, workmanship seems OK. We will be getting the existing drawings.
My main question is...
I've been asked to review an existing multistory concrete structure that was left unfinished for 13 years. Client wants to know if the building is salvageable. All of the above grade walls, columns and slabs have been exposed to Canadian winter freeze and thaw without any air entrainment or...
I've never seen a UL steel assembly that didn't have some kind of protection for the steel. The closest thing I know of is a procedure in NBCC for concrete filled HSS columns that don't need to be protected on the exterior. This is the last hope for an architect that doesn't like the colour or...
I've often done this for small isolated deflection issues on otherwise appropriately thick slabs. I've been told by contractors that it is cheaper than thickening the entire slab or locally thickening the problem area but this could vary by project.
I've never increased all of the rebar to solve...
No poly so I was a bit worried about the bond between SOG and footing but I suppose I could just ask for some poly placed over the footings. There are just a few locations where this condition occurs (most of the slab is 150 thick).
I was also worried about the differential settlement between...
I have a situation where there is not much space between the top of footing and underside of a warehouse slab on grade (55mm). At this stage it is likely too late to change the steel (pre-eng) and I would rather not add a little plinth to the footing to increase the gap but could if absolutely...
