PROJECT 1
CONSTRUCTION OF MULTISTOREY BUILDING

Excavation, Layout and Foundation
 Excavation is a process of making trenches by digging up




of earth for the construction of foundations and
basements.
Excavation level at escape site is 219.825 mm
Excavation is done by the JCB on the hourly basis
After the excavation the surface is leveled called surface
dressing
Layout is done on the PCC poured over leveled surface.
Column and foundation (raft ) steel is then laid as per
drawings.

Points to take care: layout should be checked properly.
 Check any difference between architectural and structural

drawings regarding location of column.
 After excavation check the stability of temporary structures built
near the excavated ground.
 Before laying raft reinforcement, shuttering wall which is mainly
brick wall should be built and should be filled with soil on other
side.
 Check the direction of chair bars in the raft
