The rebars (1) must have a length of 5.50 m instead of 5.52 m due to a minor difference (where the left upper horizontal part of the bentup rebar becomes 0.72 m instead of 0.73 m and the right upper horizontal part becomes 0.181 m instead of 0.182 m). The rebars (2) will be formed with a length equal to 4.50 rather than 4.33.
Lapping (45d) in bottom bars lap should be provided at column junction or L/4 distance from column face but should not be in mid span of beam.
