OSHA Regulations

Hello all,
I am trying to track down the OSHA regulations relative to the construction and maintenance of a dual I beam structure to ensure that I remain compliant. I have called the department of labor and they were of no help. If someone here can point me in the right direction I would greatly appreciate it.

We are taking offers for purchase of our property.
It has two boards on it. A 10x22 and a junior board.
It has permits held by Fairway outdoor HOWEVER there are no current lessees in effect and can be negotiated by a new owner! -In March we issued them a letter stating the leases will not be renewed.-

The address is:
11304 US-221
Woodruff, SC 29388
Tax map #4-32-00-050.01

Send your Letter of intent to purchase to Christopher@capitalmatters.us
