Hybrid construction

Hybrid construction is generally taken to be the combination of in situ concrete with precast concrete units, such as in situ columns with precast floor slabs and vice versa. The selection of the appropriate construct method will depend on many factors, such as the required surface finish, speed of construction, access etc.

Reference should be made to;
Construction/Precast methods and Construction/In situ methods respectively.

An alternate form of hybrid construction is the use of permanent formwork, made from a variety of materials. The formwork may or may not contribute to the load-carrying capacity of the unit.

Reference should be made to;
Formwork/Permanent formwork and subsequent sections.

Finally, precast or in situ concrete may be structural steelwork, such as steel columns or frames with concrete floor slabs.
