The cope looks great too!

I have access to a PEMB manufacturer's program. It's something our company negotiated with one of the big players in the industry. It's definitely a black box and I'm not an expert user but I can use it well enough to get decent preliminary loads to use for initial foundation sizing, but I...

This almost doesn't even need designed (#5 @ 16" work easily). Someone competent in masonry construction could have built this successfully.

Pretty hard to tell from that picture. I don't think we have a complete breakout cone failure. To me it looks like a spalling around the bar.

I think the main issue is there are no bond beams in this thing. The vert rebar also looks to exceed 16" but the dowels embed into the concrete sure don't look failed. Really really lucky someone wasn't between the building and CMU wall when this happened.

Looking for some input on typical corrosion allowances for D100 welded steel water tanks. Working on a spec and I want to be reasonable compared to an industry standard. The D100 standard doesn't provide any specifics that I can find. Any experience on this forum?

I'm not saying to over engineer just to compensate for lack of maintenance, but I know if a deck fails (and there are many examples) there are frequently serious injuries or deaths. I don't want to be scrutinized because I attempted to justify a lighter design load or high duration factor even...

Lots of examples of deck failures that make 100 psf not seem ridiculous. What if that 180 lb person and all his friends start jumping up and down? Now you factor in lack of maintenance that could reduce capacity. I'm probably not going to try to cut hairs on a deck design to save a few bucks.

Nothing like cheapening the profession.

There are a lot of places in this country where building departments, building officials, and permits do not exist.

In the technical sense even if KootK stays unbiased there is still a conflict. By definition a conflict of interest is defined as when personal or financial interests conflict with professional or fiduciary responsibilities potentially compromising impartiality or judgement. IMO the key word...

This isn't normal in my world of engineering. We design something and the builder constructs it. We don't reverse engineer something already constructed to make sure it works.

This is after the fact though. Is what I did OK? That's a monumental difference between, "Hey, Mr. Koot here is a problem can you help me with a solution?". In this situation if KootK doesn't agree with the solution and wants to make the contractor do something more elaborate he risks 5-10%...

I agree with this take. The contractor has engaged you and is paying you to approve their fix. That absolutely is a conflict of interest. Doesn't mean you'll act unethically as you very likely will do the exact same thing in this situation if you were paid by the homeowner. I think this is...

I know of an SE that couldn't design himself out of a wet paper bag. He got grandfathered with an SE when Alaska started requiring SE's to design all of the oil and gas infrastructure roughly 7-8 years ago. Not sure if he could use his Alaska SE to get reciprocity in a state like Washington...

Find yourself a masonry textbook or design guide. Amrhein is really good. We still use an old version of his book in our office.

Working on a project that has performance specifications for both D110 and D115 specs. Our D115 spec language requires bonded tendons throughout. The D115 tank guy doesn't like this requirement because it adds cost to their tank. I understand their consternation, but I really don't know if we...

D115 is a post-tensioned concrete tank with internal tendons. Doesn't have to be buried but in our case it is. I'll try to post over there.

Bumping this back up. I was hoping someone would have an opinion.
