The raft foundation is also known as raft plate basis. the independent foundation under column or strip foundation are all connected with connection beams, and then cast baseplates. Generally speaking, raft foundation is used when the ground bearing capacity is uneven or the foundation is weak. And raft foundation is buried relatively shallow, which can be the foundation with no need of burying deeply. It is composed of baseplates, beams and other components. Buildings have a larger loading, and the foundation bearing capacity is weak, thus concrete baseplates are often used which can bear buildings loading, and form the raft foundation with good integrity, can be an excellent resistance to differential settlement of foundation. Project quantity should be calculated by cubic meters, the quota is the all-round foundation (05 quota)
The project quantity of earthwork, rebar, concrete, mould should be calculated respectively by cubic meter, and the quota is all-round foundation.
As for raft foundation, getting the volume under the baseplates is important, and I will not repeat it. As for actual project quantity, construction joints are generally left above the baseplates for about 30 cm, the project quantity of shear walls should be counted.
