Typical lap splice locations and set out dimensions for top and bottom reinforcing in concrete slabs spanning across typical columns. The top reinforcing lap splices are located at a distance of 0.3 times the span length from the supports, while bottom reinforcing laps occur over the intermediate column supports within a designated lap splice zone. Adjacent lap splices are staggered to prevent reinforcing congestion, and reinforcement is shown in a single direction for clarity with sizing sized per plan. Grid lines establish the primary span dimensions L1 and L2.
