We have the qualified expertise to plan specific development layouts with all services, to coordinate operations and to contribute to the success of the project with expert construction supervision.
Adjacent to the Mobile Airport in Alabama, USA, an aircraft factory with all necessary production and infrastructure facilities has been constructed on a total net area of 40 ha. All production halls are connected to supply and disposal pipes. Furthermore, high load vehicle roads, parking spaces, taxiways and apron areas for the aircraft series of A320 were implemented. Sellhorn´s functions as a General Design Contractor comprised the design of all production buildings, hangars and the entire infrastructure facilities.
For the production of the Q5 model and its successors, AUDI MEXICO S.A. de C.V. has built a new car plant at San José Chiapa in the State of Puebla, Mexico. The factory’s area encompasses a total of 240 hectares.
The works designed and supervised by Sellhorn Ingenieurgesellschaft covered the entire infrastructure of the plant facilities. This included all surfaces and their specific installations, truck docks and the dedicated superstructures, the road network as well as a test track, a storage and transhipment area for the new vehicles, and further logistics areas such as a container yard and trailer yards.
Beginning in 2016 and ongoing until 2018, the Flughafen Hamburg GmbH is reconstructing its approximately 250,000 m² large airfield. Aditionally, the related taxiways and runways with an area of approximately 60,000 m² are rearranged. The reconstruction comprises the renewal of all piping systems, technical facilities and the surface.
In the course of modernization measures, the existing drainage concept had to be fundamentally redevelopped. This requirement resulted, on the one hand, from the construction of a "closed" flood-water protection system (protection by means of sheet pile walls) around the previously unprotected premises, which would have lead to a build-up of the seepage water in the area of the site. On the other hand it became necessary due to the sealing of various tank areas for environmental protection reasons (conversion in liquid-tight lining using PEHD film and drainage systems).
For the extension and the modification of the Container Terminal Burchardkai (CTB) all surfaces and piping systems were designed by Sellhorn. The conversion of the existing container surfaces of a pure straddle carrier operation to an operation with rail cranes (TRMG – Triple Rail Mounted Gantry Cranes) was the main design issue.
Due to increased storage requirements for base oils, Vopak Dupeg Terminal GmbH has extensively refurbished tankfield 02. Another goal was to expand the existing storage capacities for base oils from 6,000 m³ to 30,000 - 40,000 m³ in order to further strengthen the import and trade via the logistics hub Hamburg. In the course of the refurbishment and reconstruction measures, the existing tanks were upgraded according to the product requirements or dismanteled. In addition, the tank field was supplemented by various facilities.
The West Qurna oil field is one of the largest oil fields in Iraq. In order to ensure reliable supply of the production facilities with all required materials, various warehouses, an office building, a security office, an inspection site for customs, a clean zone as well as security installations and 80,000 m² of paved open storage areas, roads and parking areas were constructed on an approximately 50 ha large project area.
Adjacent to the "Tianjin Airport Industrial Park" in Tianjin, China, an aircraft factory with all necessary production and infrastructure facilities has been constructed on a total net area of 70 ha. All production halls are connected to supply and disposal pipes. Furthermore, high load vehicle roads, parking spaces, taxiways and apron areas for the aircraft series of A320 were implemented.
On the premises of Airbus Operations GmbH, a run-up facility for the testing of the A320 aircrafts was built in order to fulfill the local noise restrictions. In addition, the associated taxiway and media connections were constructed. All surfaces for the flight operation are made of concrete. Since the surface of the stabilizing device can also be used for loading and unloading the aircraft, this was designed as a water proofed / sealed surface.
The new car manufacturing plant in Wrzesnia is the second production facciltiy of Volkswagen Nutzfahrzeuge in Poland. In addition to the halls for the car body construction and vehicle assembly, a paint shop and a test track were built on the 220 ha large factory grounds. With a maximum production capacity of 100,000 vehicles per year, more than 3,000 jobs are created.
Sellhorn Ingenieurgesellschaft mbH was assigned by ASSMANN BERATEN + PLANEN GmbH to carry out all design stages and the site supervision for the construction of all infrastructure facilities.
Beginning in 2014 and ongoing until 2018, the Container Terminal Hamburg GmbH reconstructs the approximately 280,000 m² large hinterland area beyond berth 4 and berth 5. The rearrangement comprises the renewal of the pavement including an area for dangerous goods, adjustment of the surface drainage including facilities for the treatment of rainwater, construction of pump stations and the adjustment of supply and disposal systems (water for firefighting, cable empty pipings, etc.).
