Prefabricated ConstructionThe Construction using precast concrete has thefollowing advantages.a) Precast elements produced in factory environmentcan be worked to a very high structural orarchitectural standards.b) Precast elements is more durable when compareto structure constructed in in-situ concrete.c) Elements can be stressed to produce structures ofhigher performance.
High quality precastelements can be producedin well-equipped castingyard/factory
