Passive House School in Frankfurt-Riedberg completed!

15.04.2013 - The Riedberg Secondary School in Frankfurt am Main has gone into operation on schedule in early April being the first secondary school new building project in Frankfurt since 100 years.
In addition to the deadlines the budget could be met.
Acc. to the guidelines of the City of Frankfurt, the building complex has been realized consisting of school building with cafeteria and auditorium as well as gymnasium and youth center as a certified passive house.
CSZ was given the interesting and challenging task of building services design and supervision, including ventilation, refrigeration, plumbing, extinguishing systems, heating and elevators.
Special attention is to be given to passive house ventilation. In this case a supply and exhaust system with high heat recovery for the classrooms was realized allowing for 600 m³/h air change per class room, activated by motion detectors.
Part of the supply air flows via the corridors to the restrooms where it is used as exhaust air. Active cooling is only foreseen for the computer labs, while classrooms are equipped with a passive night-time cooling. In the area of auditorium, foyer and cafeteria the air-handling system is equipped with adiabatic cooling (evaporative cooling) using collected rainwater for evaporation.
A special feature of the school building is the high pressure water mist extinguishing system. Due to the open atriums and the resulting intense fire precautions, such as 'G90' fire-protective glazing, fire dampers, etc., the use of a high pressure water mist extinguishing system was evaluated and as a result investment and operating costs could be economized.
We would like to take the opportunity to thank the design partners, experts and contractors for their cooperation. Special thanks to architects Ackermann and Raff from Stuttgart for their close coordination.

As part of the infrastructure activities for a new coal-fired power plant, the sophisticated prefab component construction for the new central warehouse, including an office level and rooftop information center, is currently arising.
The building under construction has a base area of 2400 sqm and will accommodate a 10m high - area by area dynamically rail-mounted - high-bay racking with state-of-the-art logistics.
At the upper floors high-quality office space with a structurally integrated component cooling system as well as an information center, including representative exhibition and seminar rooms, will be realized.
CSZ is entrusted with structural design and building physics.


Opening Ceremony in China

The board members of Karl Mayer China together with high-ranked representatives of politics and economy were opening the new factory of Karl Mayer in Wujin (Jiangsu Prov.). The production halls and related buildings (department, canteen, guesthouses and apartments) and also extensive infrastructure works were performed within 15 month according to time schedule. Up to 500 workers are employed in the new factory. International experts will educate lokal workers and live in the apartment building during their stay.
After design and supervision work is done, CSZ engineers are mandated to supervise corrective actions during the liability period and document the final results. Also the in-house facility management will be familiarized to the plant and technical outfitting by CSZ.


CSZ mandated to design " Klassikstadt "

The contract of structural design was awarded to CSZ Consulting Engineers. The reconstruction of an ancient architectural protected factory building into a modern premise requires extensive rehabilitation work and special design know how. The investor will offer a distinguished ambience to the visitor with repairshops and exhibition areas made of glas structures.

Science and Event Centre Darmstadt

CSZ assumed the structural design of the Science and Event Centre Darmstadt, the new building for a multifunctional convention and exhibition centre (Cybernarium) with two basements as underground parking. Highest level of difficulty for the structure due to slanting pylons and box-type construction. Wide-spanned composite steel-concrete constructions, three-dimensional folded plates, foundation on geological Rhine fault.
For promotion purposes of the location the City of Science Darmstadt and the Institute of Technology opened a multifunctional convention and exhibition building in the city centre. The building disposes of a divisible hall with stage for approx. 1200 persons optionally with flat or staggered seating, approx. 2000 m² exhibition halls as well as approx. 1200 m² flexibly divisible conference and lecture rooms and gastronomy. The premises are accessible via a capacious lounge owing a glass roof. The draft of Chalabi Architects which won the international competition was realised with exemplary effectiveness of resources in order to minimise the consumption of energy and water. The optimisation of the thermal building covering and the proof of thermal and sound insulation were as well part of the ordered scope of work.

Prof. Dr. Jörg Schlaich received the award for engineering the Humboldt harbour bridge and Wolfgang Strobel and Dietmar Feichtinger for the elegant Rhine crossing.

CSZ is charged with the overall planning of an industrial plant

The company Karl Mayer (China) Ltd. is erecting a new production plant for textile machinery on an area of 175000 m² in the new developing area of the city of Changzhou, Wujin.
In addition to production halls and storehouses there will be buildings for administration, factory canteen as well as accommodation for foreign experts in an apartment hotel and in three guest houses.
Initially, our tasks as responsible for the overall planning were to specify the requirements of the owner and to convert them in a construction plan. The logistic processes for the optimisation of the production and the functional demands on lifting and transport devices in the halls took centre stage. It was essential to store machine tools vibration-free and to provide column-free surfaces for the transport of big knitters. Certain production areas are subject to special demands on temperature and humidity. Referring to the administration building, the factory canteen, the hotel and the guest houses there were high demands not only on functionality but as well on design which have to correspond to modern European standard. The design of the facade, the interior work as well as the range of colours were given in the draft and beside the functional tender completed by important details. The site development by means of roadways and media alignment and the connection to the available infrastructure were effected at the same time with the draft works for the buildings. The awarding of the contracts was made according to the FIDIC contract sample „Plant and Design Built“ in January 2007. The examination of the implementation planning of the general contractor and the quality of execution of the construction work as well as the control of the time schedule and costs is realised by our local site supervision. The entry of the machine tools in the production halls is stipulated in the contract until January 2008, the completion of the total plant until April 2008.
