Flowchart for the model development of 4D GIS
Work Breakdown Structure ( WBS ) for a residential building in overcoming the limitation of the software . 4D GIS technology includes integration of 2D drawings from AutoCAD and schedules prepared in PRIMAVERA software .
In the study referred to in this article , a multi-storey residential building has been selected . ARCMAP 10.2 is used for interlinking of schedules as well as drawings and ARCSCENE has been used for developing the 4D view . This linkage between scheduled activities and respective drawings in GIS helps in identifying construction sequences and also in detecting logical errors that occur in project schedules . The developed 4D view provides better visualisation of construction progress of a project .
Successful completion of a project is possible only by the proper planning and scheduling of activities . This successful completion of projects results in overall optimisation in cost and time [ 1 ]. Construction progress of the project should be monitored at every time . Project monitoring acts as safety step in construction projects which alerts and advises the organisations about occurrence of construction failures and delays . It includes the process of collecting , analysing , and recording information regarding the project .
Reference [ 2 ] describes some of the conventional methods which are widely used by the construction managers for scheduling are bar charts , critical path method ( CPM ), and programme evaluation and review technique ( PERT ). Construction scheduling tools such as Microsoft Project ( MSP ) and PRIMAVERA are used for the preparation of the construction schedule . These scheduling tools are not able to provide digital information ( drawings ) for the respective construction components and construction activities which are identified in scheduling software . For better understanding of construction sequence and for providing better
