JFE Group （JFE Engineering,
JFE Steel, and JFE R&D） have developed
QCIB （quick closing integral bridge） Method
to construct grade separation bridges at intersections
in urban areas quickly, safely and economically
by designing the entire bridge including foundation
as a bridge system. QCIB Method is composed
of several kinds of established core technologies
on fundamental design method and construction
one. The paper describes the outline of the
Method and core technologies.
