A job description requires "experience computing materials for specification level engineering projects." How is a "specification level" project different from any engineering project that uses specifications?

David, Thank you for the straight-up response. John

OK, Here is the spec I am referring to. The question is What, if any, downside would there be for substituting IA for IC as supports for chain link fence, as it appears that for the same OD, the wall thickness is such that moment of inertia is about the same for each...

At the risk of being a bore, I will repeat that 500 K was a typo. With regard to what happened on this forum a year ago, I cannot comment. Thanks for this historical note.

"Pipes, Pipelines...": seemed like the right forum.

I uploaded the standard spec I referred to (F1043-06), but to Engineering.com, but it does not show up with the post. Have to figure out this gadget.

That would be 50ksi

What is the basis for describing pipes as group IA vs IC? For example, looking at ASTM standard spec F1043-06 for industrial chain link fence framework, the Group IA designation is given to 30000psi steel, where the IC is for 500000 psi steel. So the IC has a lower weight per unit length for...

I talked with the state LT2 coordinator, and she confirmed it. Will be sending a letter to the utilities on this. Turns out the owner and city engineer knew about this but weren't too chatty, so I was the last, not the first to know.

I don't see anything from the EPA or any chatter on the web. Is there any source that can be quoted on this?

Oh! Thank you for this tip. I will sound like the smartest person in the world if I break this news to the owner.

I was reviewing some of the rulemaking discussion for LT-2 in the Federal Register, but it was breaking my eyes. It seems that one assumption in the cost-benefit analysis was that only a small percentage of small filtered systems would fall in bins above 1. Does anyone recall how they made...

I recently started working on different (but older) computer. It is loaded with LDT2004 or Map 2004. I have placed a border and various elements in a layout (11x17, which fits the format of the printer). I have done some successful prints, but suddenly, the entire drawing is offset about 2...

I have heard mention of Merlin. So far I have just followed one of the wise suggestions above, which was to not use Print Preview.

Civilperson or anyone else: If 9" maximum both ways is considered child proof, what would be the maximum one way, as in parallel bars? (I probably should be looking at a building code, I guess.)

A new residential subdivision has some unfenced storm water detention ponds. Inlets and outlets are as follows 6-12" smooth PVC inlets connected to catchbasins 1-18" corrugated HDPE outlet from pond to flow-control manhole 2-18" corrugated HDPE inlets to wetland from pond flow control and...

IFRs, As I mentioned above, apparently, PTC does not offer this if not downloaded before August 1, 2008. Does not matter when you bought it. I do not understand this policy, as in makes no sense for someone who recently purchased, as we did, but did not encounter the bug until after the...

Out of luck here. Have MathCAD 14 (academic version) since the summer of 08 as required software for some courses I am taking. Suddenly it is crashing upon the "Print Preview Command". Learning from PTC that they were only fixing this bug (as described through the downloading instructions...

How does a Mills knife work for perforating well casings?

Thanks, Ozzy84. Now that I have learned to read, it turns out "Leader" command is what I was loking for. "Dim+lea" does not seem to be affected by DIMASSOC.
