An Innovative Approach for Generation of Virtual Construction Model and a Time Location Plan for Road Construction Projects

Abstract:Construction managers require innovative techniques to assist them in producing accurate planning tasks such as resource allocation and costing of activities, because of unique characteristics of the road construction industries. The research study introduced a framework for Virtual Construction Model (VCM) that includes 4D modeling and automatic generated time location plan for earthwork activities in a road project. The framework is designed by integrating road design data, quantities of cutting and filling sections, variable productivity data, algorithms for 4D terrain modelling, and a progress profiles visualiser. The model is validated with a real life case study of a road project and it was found to be beneficial in gene-rating the 4D terrain surfaces of progress, cost histogram and a time location plan with more accurate infor-mation of location and time in the earthwork operations. The VCM has potential to assist project planners and construction managers in producing efficient construction scheduling and resource planning.
