iTWO simulates the project virtually in 5D before it is realised physically at the construction site. 

Effective and informed decision-making, as-planned quality and real-time control benefit your project outcomes by more than 30%



Cutting edge 5D planning and execution

iTWO is a fully integrated solution spanning the whole lifecycle of asset creation projects, with an interactive Building Information Model (BIM) based graphics process that integrates planning and execution phases from end to end.

iTWO integrates traditional estimating, packaging, controlling and execution, revolutionary 5D capabilities (3D Integrated model + time + cost) and project collaboration into a single software platform. 

Virtual construction management is the future

According to leading owners, consultants and contractors, the future lies in virtual construction management. iTWO enables you to improve the quality and cost effectiveness of your projects in all phases and its visual presentation makes it much easier to interpret data and statistics.

Why 5D?

A 3D BIM model is a computer model of a building containing location, geometry, property and attribute information on the building components. What you see is what you build. But what constitutes the 4th and 5th dimensions?

With 4D, you get a computer model that integrates building component information with the respective start and finish times of construction. What you see is what and when you build.

Working in 5D provides you with a building information model including all process data, i.e. input/output data from processes such as supply, progress, production, budget, cost, controlling, and facility management. 
                                                                                                                               What you see is what, when and how you build.

Why iTWO?

Traditionally, data is gathered and handled in separate information silos, an error-prone and time-consuming  practice.

iTWO's Big Data base stores and manages all information, creating ONE SINGLE SOURCE OF TRUTH with full transparency and traceability.

Virtual and physical processes become aligned and you maintain a full overview of your projects and assets at all time. Not only does this knowledge accumulation enable you to find the best possible solutions at optimised cost levels, decision-making is based on real-time information and control.

A walk-through through iTWO functions


BIM 3D integration

Time savings

Early warning

iTWO integrates into your 3D BIM model and extracts quantities directly based on the design model. This enhances the estimating process, improves benchmarking validation and enables engineering option values to be quantified concurrently with design changes.

Time gained from synergies and the integration of 3D designs, cost and time significantly enhances and enriches project data sets for all professional disciplines involved. Initial analyses by construction customers suggest time and cost savings potential of up to 30%.

Early warning of design errors starts with clash detection. iTWO identifies and alerts you to any clashes. This enables the commercial team to validate the design process prior to commencement on-site and seek early resolution to variations and changes.

Risk reduction

Change Mgmt.

Quantities can be linked directly to the production model and tracked as they are installed. Direct integration with scheduling and invoicing provides increased control in relation to time and cost management. 

iTWO makes managing complex projects more transparent and less risky. Risk reduction can be achieved by integrating planning and design decisions within the iTWO 5D software. 

Changes to construction processes and the resulting changes to costs and deadlines can be easily and clearly performed using the model.


Virtual = Physical

Using iTWO, you can simulate different design variables, calculation processes and execution variables, precisely following, controlling and minimising the project risk profile by selecting and deselecting variables virtually before construction starts.

The results are significant, with reductions of up to 80% on change orders, a more stringent cost profile and fully minimised risk.

The best features of virtual design

Virtual design is the basis of innovation and competitive advantage in e.g. the automotive and machine engineering industries when it comes to time-to-market, cost control, design and quality. RIB has now adapted this technology for the construction industry (AEC). With RIB's solutions, you too can benefit from considerable time and cost savings in implementing your projects. The relevant model information is available to the design team, estimators, planners, engineers and the executing team in every phase and lets you track the geometric, resource and process planning data for your building projects whenever you want - right to your screen. 


iTWO 5D LAB is a process laboratory, in which our clients can make use of the latest technology to cooperate on their projects, whether they are using iTWO 5D or our project extranet. We gather the project team and simulate the deployment of our solutions using the client’s data. We bring together all the skills that are needed to create the best results for the project’s parties, thoroughly testing the software solution that will be deployed on the project in a high-tech environment. In all modesty, we believe that our solutions, our global labs and our expertise are revolutionising the construction industry - and everyone is welcome.

It´s Your Industry That Counts

RIB is one of the world´s leading providers of turnkey software solutions. Our experience spans the AEC and EPC markets including Civil Infrastructure, Process and Energy, Manufacturing and Public Sectors, all of which are benefiting from successful projects managed with RIB software. 



In the design process, during construction and in operation: RIB offers individual solutions for all phases of a construction project.

Architects and engineers rely on RIB's budget preparation and tender processing as well as project management software solutions. Intelligent stress analysis and dimensioning systems ensure lasting success. 


Complex plant engineering demands maximum data availability and process security. As a universal software solution for costing, scheduling, cost estimating, tendering and project control, RIB sets a new standard in engineering and construction for: air, gas and water supply systems, heavy plants, power stations, petrochemical/chemical plants, hazardous waste plants, telecommunications plants, transport technology and shipbuilding.


By road, rail and air. Above and below the ground, RIB solutions establish reliable connections long before projects are completed. Similarly, in infrastructure management RIB links the data and information of all those participating in the design and the execution of the project: supported by transparent object-oriented design processing and the RIB's cost management system.
