| Research Abstract |
Methods of construction of (the parts of) a building are not necessarily determined during its design phase, but in fact much of the methods with the definition of corresponding components is determined through the construction phase. This is particularly true with reinforced concrete structures for which a variety of methods including pre-cast and in-situ techniques are usually considered. Design and construction, therefore, are not separate processes, but must be treated as aspects of a dynamic configuration process. This paper presents the outline of the development of such configuration system which combines a 3-D CAD system to define formal attributes of components and a matrix-based network calculation system to evaluate resource allocation. The CAD model to start with is one continuous solid object, in fact an aggregation of solid objects resulting from any way of dividing components, representing the structure as completed On assuming the optimal method of construction for a part of the structure, the CAD object of the part is defined using the Boolean algebraic function of the CAD system. The definition of the whole methods and object is done in a consecutive manner depending on the interest and insight of the construction planner. The algebraic attributes of the objects are then fed to the network calculation module which is linked to a DB storing performance descriptions of various construction methods. The construction planner evaluates the calculated overall performance of his plan, and repeats modification if necessary. The sample project to which the configuration system is applied is a reinforced concrete structure of a high-rise apartment block, and the result shows the effectiveness of the system which fits well with the actual construction planning practice.
