DEVELOPMENT OF 5D-CAD BASED WORK PROCESS MODEL FOR AGED-HOUSING REVAMP PROJECTS
Abstract: A growing number of aged-housing building projects have become a great concern in Korean building industry nowadays. Until 2010, over 20 year-old housing units are reported to exceed more than one million. The aged-housing units are required to upgrade the performance on both structural and service issues. Compared to new building projects, revamp projects are relatively under developed in terms of construction management. For example, there is few guidance or detailed procedure which addresses the management practice in dealing with revamp projects. Therefore, new technologies are reluctantly implemented in the revamp projects without in-depth analysis on constructability and/or economic efficiency. The objective of this study is to provide a new approach in dealing with aged-housing revamp projects. By developing 5D- CAD based work process model, project managers are effectively informed of various data, i.e., building elements, network scheduling, and cost items. The 5D-CAD based decision making can also enhance the accuracy and promptness during project execution. The authors developed a standardized work process model in dealing with 5D-CAD modeling via Virtual ConstructionTM software. In addition, the model has been implemented to pilot aged-housing project for the purpose of validating the feasibility and applicability in real future projects. The proposed WBS(Work Breakdown Structure) and CBS(Cost Breakdown Structure) have been proved as useful tools for contractors who deal with aged-housing revamp projects under circumstances that there is few historical projects and few experienced personnel. Also, the study identified potential benefits and limitations of the 5D-CAD based construction process for revamp projects. Key findings from this study are as follows.- - - - -5D-CAD modeling is no more optional strategy in maximizing the project value. The error-free construction planning is much more essential in revamp projects. Sharing the real-time project information can overcome communication barriers. Collaborative works are definitely can benefit from 5D-CAD modelingFull scale usage of 5D-CAD modeling can be achieved by partnering contract
