Usability, future value and sustainability play a major role in the designs we produce and the advice we give. Increasingly, we are turning our attention to related markets, such as water and energy. We contribute to accessibility through our unique combination of expertise. Movares operates throughout Europe and has offices in the Netherlands, Germany and Poland. An engineering consultancy based on engineers Movares has some 1400 professional staff. In all they do, they are ‘professional, enterprising and human’ – reflecting our three core values. Our engineering consultancy is engineer-based. That means we focus on developing our people. The result: ideas and solutions that contribute to sustainable development. Development maintaining a healthy balance between social relevance, quality of life, sustainability and economic growth. To us, socially responsible business is not just something you do. It’s what you are. And our customers notice the difference. Giving shape to mobility Infrastructure is the backbone of development, both for society and for the economy: from initial studies and the earliest planning phases, to the design and execution of projects and further on to management and maintenance. Movares plays an active role throughout the entire consulting and engineering process. Our combination of knowledge, expertise and innovativeness is summed up in our motto: ‘Giving shape to mobility’. Projects Movares is involved in a wide range of projects. Those of which we are mostly proud include the dedicated freight line from the Netherlands into Germany (the Betuweroute), the high-speed line into Belgium (known as the HSL-Zuid), doubling the number of tracks between Amsterdam and Utrecht (the busiest line in the Netherlands), several projects in the port of Rotterdam, a highvoltage switching station and a new public transport terminal in Utrecht. Introduction The present buildings for the Utrecht Central Station have a capacity of 35 million passengers per year. Nowadays the station is already used by 55 million travellers annually. In the next twenty years the number of travellers will raise to about 100 million. The existing building cannot accommodate these numbers of passengers. The plans provide in a state of the art building to integrate all public transport facilities and shops within one location. The new public transport terminal (called OVTerminal) will be the largest station in the Netherlands in size as well as in transit values. The realization of the OV-Terminal is planned in the period 2010-2015. As the station needs to remain fully operational during construction, works will be executed in phases. Design OV-Terminal The OV-Terminal will consist of a concrete floor structure and a steel roof structure. The concrete traverse is a structure of repeated concrete columns supporting tie beams and PI-beams which connect the tie beams such that they act as portal structures. Spanning the tracks is realised by the use of TTgirders. The main dimensions of the roof structure are approximately: length 250m, width 90m and maximum height 17m. Traverse Roof structure The roof structure of the traverse consists of a main structure with seven rows of steel main girders, supported by steel columns at the existing patterns. In order to reduce the deadweight of the structures and the possibility to utilize large spans, steel as main material was chosen instead of concrete. For the benefit of the double sided curved roof surface, the main girders are singularly bent. On top of these girders the curved purlins are mounted. During assembly the purlins need to be slightly twisted. In fact all purlins are shaped differently. On top of the purlins steel roof plating in trapezium shapes, as in the present situation, will be attached. Due to the enormous dimensions of the roof and the temperature changes, the roof has two expansion joints in the longitudinal direction dividing the structure in three parts. The stability in transverse direction is realized by the application of steel tension-compression shores. In longitudinal direction per pattern and per separated part, a steel stabilizing element is applied. The elements consist of two columns connected by buckled elliptically shaped and tapered beams and at the top the columns are connected by wires as wind framing. Near the roof cut, also called “the eye”, for architectural reasons it is decided to apply “Vierendeelliggers” between the higher and lower roof Public Transport Terminal, Central Station, Utrecht The project regards a state of the art building to integrate all public transport facilities and shops within one location. The works will be carried out in phases, as the station needs to remain fully operational during construction. The integral station building will be able to handle up to 100 million travellers per year. The implementation will take place from 2010 till 2015. Scia Engineer has been used to get the steel structure determined. The main construction of the roof is made out of steel and consists of seven lines of curved beams supported by columns. Across these beams are mounted girders, which are curved in one direction. The roof plating is mounted on the girders. The pedestrian and shopping areas are made out of concrete floor.
