Working from cooperation

The TBI companies Mobilis, Timmermans Infratechniek, Voorbij Funderingstechniek and Servicis put their strong social engagement into practice by providing solutions to overcome challenges in the infrastructure, industry and water markets. Together they form the Mobility cluster. TBI Infra Asset Management is also a member of this cluster. By managing and maintaining bridges, roads, locks, water treatment plants and other infrastructure works, it meets the growing demand for specific and sustainable assurances on the continuity of social functions at minimum risk and cost. A new market segment we are targeting is energy in general, and renewable energy supplies such as geothermal and biomass in particular. We have already identified interesting growth opportunities where we can benefit from our design and build expertise in this sector.

2016 was a stable year. The improvement in market conditions was reflected in the number of tenders. Our efforts were rewarded with contracts for the first part of the construction of the Rijnland Route, a new link road from Katwijk to the A4 motorway near Leiden, and for the enlargement of the lock at Eefde.

Control from start to finish

BIM is of particular importance during a project’s preparation. Project management, however, is of unmeasurable value during the planning and organisation of large integrated projects. Mobilizer, a state of the art automation tool, enables the TBI companies to control and direct the most complex tenders and projects from start to finish. The technology is developing rapidly and the TBI infrastructure companies are investing in the changes and working with Croonwolter&dros to improve and add to the tool. It is currently being augmented with more extensive data management systems. The web-based system stores, manages and interlinks all information on the operations, tenders and projects. All authorised users (including clients) can retrieve all the information. An important feature of the system is that it is scalable and can be adapted to the requirements of each project. The system must grow into a digital project management and information tool that controls and directs the TBI infrastructure companies’ business processes, tenders and projects. This knowledge will also be shared with the other TBI companies so that the system is a source of integrated information for use throughout the group.

More maintenance projects are also coming to market. The government has long postponed the maintenance of roads, bridges, tunnels and viaducts. It is now being forced to bring forward the renovation of major infrastructure works and plan their maintenance more systematically. Substantial investments will also have to be made in repairing and maintaining bridges and strengthening dykes in the years ahead.

In anticipation of these changes, we used 2016 to strengthen our basis. We enhanced the interaction between the TBI Mobility companies and sharpened their focus on joint marketing. We also worked on the further development of our systems, including our digital management and information system, Mobilizer.


TBI believes in the strength of cooperation. On large complex multidisciplinary infrastructure projects, the TBI companies complement and strengthen each other by working together. During the tender phase for the Máxima bridge near Alphen aan den Rijn, for example, Voorbij Funderingstechniek mapped out the transport logistics for the foundation equipment and materials with a view to minimising the CO2 emissions. Mobilis built the bridge in collaboration with Hollandia Infra and Van Gelder, while Voorbij Funderingstechniek was responsible for the piling platform and foundations. TBI can make a telling difference in such logistically complex projects. The Máxima Bridge was a technical challenge that combined all the features of an integrated, sustainable and multidisciplinary design and build project. The most important requirement made by the client was that the bridge and its access roads had to be designed into the landscape.

The sophisticated working method and good cooperation minimised inconvenience to road users and other stakeholders during construction of the Máxima Bridge. Good environmental management is one of our strengths. The TBI companies therefore tender for projects at busy urban locations, such as the Hoekse Lijn project in Rotterdam. This project will link the regional metro network in Rotterdam to the railway line between Schiedam and Hook of Holland. It comprises the construction and modification of seven stations, the replacement and adaptation of about 23 kilometres of double track railway and overhead lines and the adaptation of two movable bridges.

To minimise the inconvenience to passengers, the conversion work itself will be completed in the shortest possible time frame. Given the complexity, short lead time and the many parties involved in the project, precise planning in combination with strict management and coordination between the client, contractor and other participants and stakeholders is essential. Mobilis is working on this project with VolkerRail and the TBI companies Croonwolter&dros and Voorbij Funderingstechniek.

During the construction of the underground bicycle park at Maastricht station, too, the trains and buses have to keep running as normal. To limit the inconvenience to passengers, the TBI companies are carrying out the construction work in phases. Mobilis is working with Timmermans Infratechniek and Voorbij Funderingstechniek. Timmermans Infratechniek is a specialist in ground engineering and concrete engineering. Voorbij Funderingstechniek specialises in piling and foundations. The two companies are good complements of Mobilis.

To build the HOV public transport link between Schiphol-Oost and Schiphol-Rijk, Mobilis is working with Voorbij Funderingstechniek and Timmermans Infratechniek, which are carrying out the foundation work. The new bus lane in Schiphol-Oost will be part of several similar HOV connections to improve access for passengers and employees at and around Schiphol Airport.

Another example of how the TBI companies complement each other is the Waterfront project in Harderwijk. Synchroon is responsible for the area development, Koopmans Bouwgroep for house building and Mobilis for the five movable bridges and the one fixed bridge that will connect the islands.

At the beginning of 2016 Mobilis, Croonwolter&dros and Nico de Bont signed a contract to renovate the Maas tunnel. Together with Rotterdam municipality, the TBI companies set up a project office to make optimal use of each other’s expertise. The project involved the renovation of the concrete structure, technical systems and the monumental features of the tunnel.

Mobilis has been operating in Denmark for many years. Demand for design and build knowledge and expertise is high there. Our know-how and experience of such contracts have already won us several engagements. In 2016 we were awarded a contract to build a 160-metre-long cycle and pedestrian bridge in the centre of Copenhagen.

Building with respect for nature

The new link road between Drachten and Dokkum, de Centrale As, was handed over in 2016. The road runs through part of the Noardlike Fryske Wâlden, a nature area of national importance. Solutions were therefore sought that would respect the flora and fauna. A ‘hop-over’ was built, for example, to give bats a safer flight path. Mobilis worked on the project as a member of the Nije Daam consortium. The project was made up of four sub-projects that included an aqueduct and a bridge. The TBI companies Voorbij Funderingstechniek and Timmermans Infratechniek also worked on the project.


Clients want to know how much their projects will cost over the longer term and are increasingly contracting out management and maintenance. They want their assets to be reliable and available at all times. Continuous availability is essential to many clients. TBI’s Infra Asset Management Division is a repository for all our knowledge relating to the maintenance of civil works and technical systems, even if they were not built by TBI itself. We challenge ourselves to continuously develop new products and services that we can offer to our clients during the contract period. Road Maintenance Support, for example, has developed a narrow, multifunctional maintenance vehicle that can work on motorway hard shoulders without additional traffic measures having to be taken. TBI Infra Asset Management is a 50% shareholder in this venture. Long-term asset management contracts give the client peace of mind and strengthen our business model. TBI is currently involved in the maintenance of the Western Scheldt Tunnel, the Sluiskil Tunnel, the Coen Tunnel, the A15 motorway at Maasvlakte and also the locks at Eefde and the Rijnland Route.


The TBI companies and their integrated cooperation also generate added value in the industry and water sectors. Croonwolter&dros provided the technology for the water treatment plant built by Mobilis in Alblasserdam. Mobilis built the plant with RWB and Xylem for the Rivierenland water authority and will carry out maintenance work for the first two years after the hand-over.

The two companies are also working together on the second chamber of the lock at Eefde. This multidisciplinary project is being carried out entirely by TBI companies. Operating under the name Lock to Twente (L2T) the consortium is responsible for the financing, design, construction and 27-year maintenance of the new lock. The lock’s technical systems are designed to be very energy efficient. The energy needed to operate the gates will be generated by solar panels at the lock complex. Materials will be supplied mainly by water and measures will be taken to ensure the work does not disrupt shipping. The companies won the contract thanks to these sustainable, creative solutions.

A major industrial project is the renovation of TenneT's electricity substations. Servicis is working on this project with Croonwolter&dros and Mobilis.
