Central zone The main building work or civil engineering
work will be under construction in this zone. Consider some of the main equipments (e.g.
Tower cranes, lifting or boring equipments).Inner zone Consider carefully locations for
loading/unloading, short term stores, storage of bricks, blocks, prefabricated elements, roof structures,..including temporary roads.

SITE LAYOUT DESIGNBatching plant Batching (radial or tower system) plants are
typical in Greenfield. On confined site (congested areas) concrete
is delivered to the site. Access around the aggregate- deposit Parking and loading bay Supply, reach/access/service of mixer/hieght
