DESIGN PHASE CONSTRUCTABILITY ASSESSMENT MODEL

摘要: Constructability is an important feature of a design where it deals with the ability to build. problems that are encountered during construction normally associated deficiencies. The more common in traditional contracting system separated from construction. Recent study found Malaysian industry constructability has been neglected for quite some times. Many designers have failed give proper consideration process. In other studies was established various principles needed be considered order improve constructability. focus this develop model can used assess based on different Improvement made fails meet minimum level conducted three phases literature review, questionnaire survey and development. Artificial Neural Network (ANN) regression techniques were An extensive review resulted identification design-related construction, phase improvement methods. Through survey, six out eighteen identified very by engineers architects industry. outcomes surveys form basis formulation beam-design assessment framework, which relationship between degree application framework enabled data collected. By applying methods models developed. best performance multiplayer back-propagation neural network consisted twelve input nodes, five hidden nodes one output node. Test results indicate method produce sufficiently good prediction even limited data-collection effort, thus provide efficient tool assessment. concluded project at phase.
