Project cost control using five dimensions building information modelling

Correctness level of data is the key of the construction industry success. Today, there is a novel widespread tool in construction sector which is building information modelling (BIM). BIM assists as a collective intelligence supply for data about a service and improves closeness among distinct stakeholder concerned in a project. The usual problems confronted by construction sector are cost increasing and schedule delays. BIM will certainly assist to reduce these circumstances. This article used a case study to show how the applying of BIM systems on a full construction project life cycle cost can decrease project budgets and enhance project time. Moreover, it is going to focus on integrating the traditional 4D BIM (project schedule) and the cost of every project item to form 5D BIM. This will simplify several cost associated actions such as controlling the construction project cost. At the end of this study, it is found out that the variance between planned costs and actual costs decreased from 12% to 5% when 5D BIM is used instead of traditional methods. Therefore, accurate cost estimates and clash finding are the useful outcomes of 5D BIM.
