One consideration might be that it should get you closer to replacing the weight in-kind, and thus be less likely to induce new settlement.
What I mean is that if you replace the 8' of dirt (or whatever it is for the basement) with a structure that is similar in terms of weight (really bearing...
Thermal mass. You have the heat of the conditioned spaced, and the ground temperature, keeping your interior footings above freezing. It's the same concept as using horizontally projected insulation as a building apron for shallow frost protected footings.
That said, you may give...
If the building is heated there is no need to frost protect interior footings. On the other hand, if the structure is an unheated warehouse, then they should be protected just as exterior footings are.
The method proposed by RattlinBog is the most common that I've seen. If you can just treat it as an infill piece then adding some secondary framing members off the existing is an easy go (shown below with new members in red). Alternatively, overlap new decking and dowel as required for your...
Sounds like EOR is saying to bypass the corbel pham. Cut and add plate directly to wall below with HSS / column presumably face welded (or alternatively an angle underneath I suppose). 3.8kips is very easily accommodated with a plate / Hilti KH-EZ screw anchors to the wall below.
EDIT - Sorry I...
I did look at what I wrote, as, well, I wrote it. The implication of what I wrote was that the only circumstance under which I would not reanalyze it in detail is if it had undergone design loads and came out relatively unscathed, and even then, if the budget was healthy I would reanalyze it...
On the other hand we don't say "we have a big concrete placement on Friday" ;)
I think this is getting a bit far into the weeds, even for the lawyers who might look at our stuff later! I'd probably go with concrete placement in a specification though, since that does seem to be the most common...
I’d base my decision on two major factors:
(A) Project Fee: If your fee is healthy then you probably should redesign since that would be in most agreement with what one ought to ethically do. If it’s a light fee, then I would tend towards replacement in kind with the caveat of B.
(B) Loading...
I practice in your jurisdiction and have had to collect unpaid accounts on both the contracting, and engineering sides of things. My honest advice is to chalk this up as a tuition payment. Any remedy you may avail yourself of (e.g. small claims, lien, etc) will just cause more pain and headache...
Did this exact setup at my old house 10 years ago, which my brother still lives in. Zero issues so far! Frost line should be measured from whatever the outmost protective surface is, which will obviously change throughout the structure. What we did was as follows:
A) heat-trace the drain at the...
Most types of bricks are brittle. My money is on someone hit it at some point (maybe early on during mortar curing period) and the crack resulted. The chip in the brick below is primarily what I'm basing my speculations off of. Though could be from swell as KootK mentioned. In any case, almost...
Hand chip the upper 6" - 12" of the column with 15lb pneumatics, and then use a metal cut off wheel on the quick cut to sever the bars. Do as you please after that.
I agree a hoe ram is likely to cause damage to whatever structure remains. That's why we restrict their use around vertical...
For what it's worth I've used aluma beams in the reverse orientation. Details in the following thread: https://www.eng-tips.com/viewthread.cfm?qid=485703
IRC is not my code but a footing in the context of insulated slab-on-grade construction is a new one for me. Even if your entire base was concrete it wouldn't be a footing, but we use concrete for footings all the time, right? It's not about the material.
But I see what you're trying to do now...
I'm a tad confused since there is no footing in insulated slab-on-grade construction (regardless of sub-base or surrounding soil materials). But if you mean to ask if granular materials may be used as a sub-base for an insulated slab-on-grade home the answer is most assuredly yes. We do so all...
When we're on T&M our rates are as follows (Ontario, Canada):
Senior Engineer (me): $190 CND / Hour
Welding Engineer (brother): $395 CND / Hour
On the engineering side I mostly do designs for our own purposes (as a contractor) or as a temporary works engineer for outside contractors. My...
Ditto what CANPRO said for the steel side of things. I can barely RFI anything these days with the required drawing turnaround by the GC. So to make timelines we do most things in the shop drawings unless things are so uncertain that I cannot proceed without clarification. I bubble / make bold...
100% agree with you canwesteng. But as you say there must have been something terribly wrong for the corporate lawyer to file a statement of defense leading with "Match admits to under design of the transfer slab and certain elements, including columns, and supports..."
As in not even remotely...
I’m a professor at a trade college where we have a mix of PhDs and folks with experience (I’m in the latter category). We’re also attached to a research university. Unfortunately, here’s the current landscape:
Enrollments are down and funding has not increased. Teaching spots are primarily...
