Building Construction Handbook, Eighth Edition

Concept ~ a cost effective simple and fast site assembly system
using load-bearing partitions and external walls to transfer
vertical loads from floor panels. The floor provides lateral
stability by diaphragm action between the walls.

Application ~ precast reinforced concrete crosswall construction
systems may be used to construct multi-storey buildings,
particularly where the diaphragm floor load distribution is
transferred to lift or stair well cores. Typical applications include
schools, hotels, hostels apartment blocks and hospitals. External
appearance can be enhanced by a variety of cladding possibilities,
including the traditional look of face brickwork secured to the
structure by in-built ties. Internal finishing may be with paint or
plaster, but it is usually dry lined with plasterboard.

Fire resistance and sound insulation are achieved by density and
quality of concrete. The thermal mass of concrete can be enhanced
by applying insulation in between the external precast panel and
the masonry or other cladding.
