RIB iTWO is a construction and engineering software that combines traditional construction planning with trail-blazing 5D planning. Using Construction Process Integration (CPI), the software integrates CAD and commercial ERP systems, to produce a 5D planning model. The 5D model lets the users track the geometric model, time (virtual construction site) and resource control in all project phases on screen. RIB iTWO uses the Building Information Modeling (BIM) approach for project control, virtual planning and simulation of production processes. The system gathers information from different 3D data sources and integrates them to form a system-generated graphical own-object model. Other key features include clash detection, quantity tracking based on design plan and automatic extraction of cost estimation based on design. RIB iTWO supports XML technology as well as ifcXML. Set-up and configuration for large network installations may require assistance from RIB technicians.
