Roof Raising Location:  Aurora, Illinois
Roof Raised:  47' 3"   Total Roof Height after raising:  67 feet
Size:  5,600 sq. ft.

The latest roof raising occurred in Aurora, Illinois, and required a 5,600 sq. ft. section of roof to be raised from 19' 9" to 67' for a 47' 3" lift.  The lift required eight 3-stage jacks, along with 105,000 lbs of structural steel and 300,000 lbs of concrete to stabilize against wind loads.

All lighting and fire water systems were installed prior to lifting to prevent work at extreme heights.  The roof was first raised 25 feet and the upper portion of the building completed.

The entire complete building was raised the final 23 feet and all structural steel installed and the sheeting completed.  The roof was raised at a rate of four feet per hour.  The client was pleased because exposure to the weather was held to a minimum, and the cost was approximately one-third the cost of the conventional method.
