In the revision, the frame and contents were comprehensively changed in order to make clear performance-based design. The fundamental concept of design is that the design, execution, and maintenance of concrete paving shall be based on the life cycle assessment in the design lifespan.
JSCE Standard Specifications for Concrete Structures -2002, Dam Concrete was revised in March 2002. The previous title “Dam” of this volume was changed into “Dam Concrete.” This volume was divided into two parts for the convenience of users.

Precast concrete shell form is the construction method which have many merit such as saving labor and wood resources at construction sites. tinder unique methods of manufacture, many types of precast shell for column, girder and wall have been developed and used. However it is the point of construction that the state of site-placed-concrete can not be confirmed by the eye for column type shell form. This report shows the results of construction test on precast shell column to confirm the propriety of quality control method and state of site-placed-concrete. And the same time, nondestructive testing of the column by thermograph was carried out.
