Regarding Glass Lift & Main Building Interface Connection, additional steel beam at glass lift side is required to receive/connect with the main building (floor) steel beam due to the TOS difference between the two structure's interface.
2) Proposed new beam: RHS 500x300xt @ lower roof level (new beam TOS 299.42)
