Building Information Modeling (BIM) is the latest innovation in the construction industry. BIM is an intelligent three-dimensional model-based process that provides architectural, engineering and construction (AEC) professionals with insights and tools to design, design, build and manage buildings and infrastructure more efficiently. As an innovative approach to the evolving global industry, ARQS is providing the BIM based cost modeling for the projects. This will increase the accuracy of the project estimation and provide more reliable forecast of the future project cost. With the integration of design and cost into the model (5D BIM), adaptation and impacts of the design changes can be monitored in all the stages of the project.
