Storage Tank Takeoffs

Storage Tank Takeoffs

Storage Tank Takeoffs

(OP)
Hey everyone,

I just started an internship with an industrial construction company that specializes in design, fabrication and installation of API and ASME storage tanks, and I was wondering if anyone had any tips/advice on the processes to go about learning how to do a simple takeoff when looking at plans for a 30'x20' 2-course (Material: A-36) storage tank. I'm a Junior at LSU in Construction Management specializing in Industrial Engineering, and am trying to get my feet wet, and I figured this would be a good place to start for advice.

Thanks in advance!

RE: Storage Tank Takeoffs

Clueless,
You might want to check on this.
I think the width of each courses on a standard API Tank are 8'-o" high. This would mean that you would have three courses and would be advised to standardize the height of your tank at 24'-o" instead of 20'-o". If you really want just 20'-o" then you will have a lot of trimming and a lot of waste to dispose of.

The plate material you need would be 30'-0" times 3.1416 (for each course) times the 3 courses.

prognosis: Lead or Lag

RE: Storage Tank Takeoffs

You're gonna need a roof up there.... 8<)

Does the API require floor plates, or rest/seal directly onto the flat concrete pad for low pressure storage tanks?

Add a few nozzles, manways, cover plates, nuts, bolt/studs. gaskets, vent pipes ...

RE: Storage Tank Takeoffs

pennpiper,

Are 10 ft wide plates not available in your location?

cluelessintern,

A good start to doing take-offs is to ask yourself "what pieces are required to build this?" If you were building a car, those things might be wheels, tires, engine, transmission, steering wheel, etc. For building a tank, you will at the very minimum require a shell and a floor. Learning to layout these items is a skill which can take years to master, but you must start somewhere. Some considerations include the fabrication abilities of your firm and shipping of the fabricated material.

RE: Storage Tank Takeoffs

clueless....

Suggest that you purchase or somehow obtain this book:

http://www.amazon.com/Above-Ground-Storage-Tanks-P...

Become familiar with all of the pieces & parts.....know the different types of roofs/ nozzles/manways etc.

Then develop a spreadsheet....
