General contractor: at this moment the contractor is unknown Realisation: 2005 Why is this project important? The number of passengers travelling by plane increased enormous last decade. In no time you can go over all the world. The increasing number of people flying demand an airport that can do its job. The existing airport is too small for the capacity & the management decided to extend the existing airport. Why is this project so special? The extension to the International Airport is really huge. The project combines the enormous size of the extension & eye for detail. The designers succeeded their mission: develop an airport where it is lovely to be. The extension is realized in a number of project teams because of the size of the project All teams worked together for one goal: to develop a beautiful airport in Jeddah. This asked a big effort of all these team members. For better structural design the project is divided in 5 parts. A short introduction to the different parts will be given: Part I New terminal buildings The new terminal buildings are situated east & west of the existing South Terminal Building. Layout has been derived from the existing terminal as well as the Concourse and Connectors. The "column grid" of the new buildings is 12x8m2, (existing building: 12x12m2). The building consist of a ground & 1st floor and a split-level basement for the luggage handling. The spatial roof system of the Connectors is extended over the central part of the new building. The rest of the building is covered with shell structures shaped identically as the existing building. Part II Concourse The Concourse is approx. 1,370m long and 40m wide and comprises a large public space on the 1st level & a mezzanine with travelators of about 9m wide. Ground level is used for airside operations, & some technical rooms. Under the Concourse a tunnel is build to uses the installations. Characteristics of the architectural design are the spatial roof structure, the open public areas, the length and the repetition. The longitudinal column distance is 12mx 12m. On ground level these large column distances provides space for baggage trolleys, trucks, busses etc. The main grid of columns under the 1st floor is 6 to 8m in cross section. Part III Connectors The layouts for the roof and floors have been derived from the construction of the Concourse. The width of one Connector is 216m at the Concourse end & 68m at the terminal buildings and. In cross section the width is about 138m. The roof height is about 33m. Underneath the Connector the "concourse tunnel" is connected to the basements underneath the terminal buildings. The (lowered) ground level & 1st level connect to the corresponding floors of the terminals. The roof of the Connector reaches its highest point at the side of the Concourse and it lowest point at the side of the terminal buildings, so it does not connect at the same level to the higher terminal roof. Using the same principles of the Concourse, an enormous space is created. Again, the aesthetics of the architecture and the construction are intertwined. Part IV Parking garages At landside of both Terminal Building 1 and Terminal Building 3 a parking garage is planned. Each parking garage consists of three levels. The height is 3.50m. Layout and structure of both garages are equal but mirrored. The garage is divided in 2 parts; resp. 108x152m and 72x152m (ramps not included). These parts are separated by a 20m wide "pedestrian promenade underground tunnel' that connects the parking & the terminal buildings. On each parking level the two parts of the garages are connected by 3 traffic bridges and 2 smaller pedestrian bridges which cross under the promenade. At both sides of the garages a ramp is designed to enter or leave the parking. The ramps are designed for one way traffic but allow 2-way traffic in cases of emergency. The columns are placed in a grid of 18x8m, Based on the dimensions of the parking places (5.5x2.67m) & the width of the traffic lanes (7m) between them. So a column-free parking zone has been created. Part V Existing South Terminal Building The existing terminal building is a concrete structure with concrete shells as roof. The grid system of the building is 12x12m2. The building comprises a ground and 1st floor & mezzanines on the 2nd floor. Luggage handling tales place in the basement. The building will be incorporated in the total design of the Basic Project. This will include adjustments to the existing structures. Use of ESA-Prima Win Description of the technical questions to be solved with ESA-Prima Win: The problem we solve in ESA-Prima Win was to study and to calculate the way forces are running through the design of the construction. So by modelling we had to decide if things are possible or not. Really special at the design process were the earthquake loads. A description of your experience with ESA-Prima Win when realising the project: ESA-Prima Win was a key player in the design process. Our engineers used ESA-Prima Win from the first sketch of the architect till the last calculation in the design process. When modelling our ESA-prima Win calculation models we used a lot the opportunity to exchange digital information with the architects. So, it really worked quick this way and the answers for the construction could be given in a fast way! Modules used: Base 2D frame 2D grid 3D frame Dynamic document 47 SCIA User Contest Catalog
