Construction of parapet involves laying of concrete in three stages namely ( i ) kerb, ( ii ) pillars
and wall panels and ( iii ) coping. While concrete laying cycle can be matched with production
cycle for kerb and coping, the laying cycle will be very slow for pillars and wall panels in view of
thin sections with reinforcement. Considering the laying time for pillars and wall panels at twice

Cycle time for batching / mixing / unloading 1 mix : 4.50 minConstruction of parapet involves laying of concrete in three stages namely ( i ) kerb, ( ii ) pillars
and wall panels and ( iii ) coping. While concrete laying cycle can be matched with production
cycle for kerb and coping, the laying cycle will be very slow for pillars and wall panels in view of
thin sections with reinforcement. For ornamental parapet the laying cycle time will be more than
solid parapet in view of openings in wall panels. Considering the laying cycle time for pillars and
wall panels with openings 3 times the production cycle time the average cycle time will be about
1.8 times the production cycle time.
Average cycle time for laying concrete ( 4.50 x 1.8 ) : 8.10 min
