be difficult for a steel fixer to handle on his own. For ease of handling, bars
should not exceed 6–8m length.
Bond laps have to be allowed for and should be at places which are con-
venient for the erection of formwork and for concreting. Starter bars in floor
slabs are nearly always necessary for bonding to the reinforcement in walls.
The length of their vertical arm should not be longer than is necessary to pro-
vide adequate bond length and support the wall reinforcement so they pres-
ent minimum impedance for slab concreting. If the designer wishes to use
