Strategies for Representation and Analyses of 4D Modeling Applied to Construction Project Management

AbstractThe application of Information Technology (IT) to construction project management (CPM) has become crucial to the completion of projects in accordance with the specifications of time, quality and costs. However, there are difficulties in visualising the planning and work progress in space and integrating information between stakeholders. Building Information Modelling (BIM) can gather necessary information at different stages of a project's lifecycle, including production management. This study aims at discussing strategies for the representation and analyses of a building construction 4D Model for planning and control and evaluating the importance and applicability of 4D Modelling to CPM, based on the survey conducted with the professionals from the Brazilian construction sector using a Google Docs questionnaire. The survey questions comprise the evaluation ofpotentialities, strategies for representation and analyses, such as the colour use for the differentiation of internal activities and alternatives of physical advance monitoring through the Planned x Realized schedule simulation or visualisation of them on split screen, ending with the evaluation of the 4D Modelling adoption. The results indicate the degrees of importance and applicability of the 4D Modelling regarding the aspects analysed based on professionals vision of construction industry
