Fig. 8-1 Rninforcing Bars Stored at Jobsite When tl1e reinforcing bor. ! arc unloaded to the storage area, it i important that the location of the ami be selccte(l for eosy access by tt UCk and rehan­ dlina of the but to the area of placement in the sttucture. Normally, mai,ght reinforcing bars are stored by si,,:s and by knglhs within one bar size so that easy identification is possible. Bent reinforcing bars are similarly stored and the tags ofbodi straight an<l benl bars are kept at the same end for easy idcn· tification.

Tags should be all in one direction and at 1he same end of the bundle to avoid wall:ina bclt and forth, up and down the bundles. When a bundle is opened and some of the rcinforeing bars are removed, tl1e bar wilh the tag. Jiould remain with lhc bundle.
