The Franna crane slowly lowers the panel into position while the two ground workers guide it using a burke (large crowbar).
Prior to any panels being lifted on site all the panel locations are marked out on the strip footings, and location pins are drilled in.
Once the structural panels are inplace, they need to be braced and propped using cast-in inserts to the panel and a deadman cast in-ground concrete anchoring brace (nominated on shop drawings).
This is a compliance/delivery document that is unique to each panel, it must have the panel id no., the date poured, the weight and strength of the panel. The crane driver can not lift a panel without this 'birth certificate'.

the photo with the panel marking , is that pad footing or strip footing? only saying it due to the fact that the structure is portal frame.
