There is no strict order. Your G.C. will have his/her preferred way. My company designs hi-rise, hi dollar condos, and I have seen G.C.'s do it 2-or 3 different ways. In most cases, the plumbing has gone in first. I personally believe that electrical should be higher than any liquid due to leaks...

If this for potabable... I suggest stainless! Sooner or later the galvanize will deteriorate. Are the supports welded? If so, the welding process will be the starting point for the degredation (there is no real "re-sealing" compound that lasts longer than the inspection of construction). If the...

While familiar with deaerators and their design parameters, I am now faced with designing a potable (stainless) hot water storage tank tank with a capacity of 1700 gallons. My questions is; how low of a profile can I safely build without having to worry about pump cavitation or lack of...

I used to work for GP in Columbus, the only governing body was - the department of industrial compliance - no one at local level is qualified to inspect or approve welds, procedures and or processes so the local governing agencies usually grant exemptions. If you are touching any pressure...

Thank you for your response.... will be most interested in learning what you find with reference to code. I have never seen this done, but came into this project well into the building phase and came across this issue by total accident. I have raised a flag within this company... To continue...

I am working on a project where a significant amount of seperate structural steel (independantly supported) catwalks/beams and cantilevered - has been "hard" attached to several new tanks on this project( I have never seen this done). I cannot find reference to whether this is allowed or not per...
