Calculations shall be made from plans of the existing <br />structure showing complete and sufficient details with supporting <br />data for the demolition the structure.

Safety factors that may have been “built-in” to the rating <br />charts are not to be considered when determining the 150% factor of <br />safety. All rigging components shall be clearly identified and tagged <br />with their rated lifting capacities. The position of the rigging in the <br />field shall not differ from what is shown on the final plan without prior <br />review from the Sponsor and the Railroad. <br /> <br />(5) A complete demolition procedure, including the order of lifts, time <br />required for each lift, and any repositioning or re-hitching of the crane <br />or cranes. <br /> <br />(6) Design and supporting calculations for the temporary support of <br />components, including but not limited to the stability of the <br />superstructure during the temporary condition, temporary girder tie- <br />downs and falsework. <br /> <br />3.
