Mr.

The city or county should have what was submitted for approval of the building, before it is built, I'm not sure to what degree of plans are archived but you may get lucky. Also, possibly the construction contractor, designers and engineers may still have copies of the as-built plans in his files or construction drawings. If this area of work was subcontracted, they may have them.

If you can find the manufacture of the SSF panels and serial numbers, they should be able to look up the original equipment specs and job order # so you could find replacements, same with the AHU's.

Good Luck

Tq for your prompt reply. For area there were no records or what so ever, that is why I am asking if anyone has any guidlines or past drawings so that I could try follow up with new suppliers that can fabricate. Tks, Best Regards

Check with the local building & labor authorities. Plans such as these must be submitted for approval even before construction can begin. Likewise, any modifications to such plans must also recieve approval before work can begin.

Thanks for your comment and will try meeting up with the authorities soon.
