Airport Lounge Modular Construction at Berlin Tegel Airport

Passengers at Terminal C of the airport Berlin-Tegel have access to a new lounge. The special feature: the three-storey modular building was built from steel modules by Cramo Adapteo in just six weeks of night installation. The fronts of the modules are glazed over a large area, underlining the cuboidal structure of the serial elements, while the lounges offer generous views.


About Cramo Adapteo

Manufacturer: Cramo Adapteo
Product: Steel modules
Building: Airport Lounge
Location: Berlin Tegel Airport
Year: 2017

The new lounge at Terminal C of Berlin's Tegel Airport, which is close to the city center, proves that modular construction is suitable for functional and fast building projects, yet not neglecting design and comfort. Cramo Adapteo, part of the Finnish Cramo Group, placed its prefabricated modules on the apron of the terminal in just six weeks. Since the erection had to take place during the running of the airport, the assembly could only take place at night. To the outside, the building retains a functional character that matches the context, to which the modular design is clearly assigned. The steel construction of each element is visible on the façade, because the individual structures optionally frame large-area glazing and the rooms behind, or outdoor spaces and access area.

From the inside, the glass fronts allow for sweeping views. The lounge areas themselves are designed to meet comfort and service requirements for stays between flights. On the ground floor of the three-storey terminal building there is a reception area and a dining area. In addition to dining tables and chairs, work tables are also available, each equipped with sockets. On the second level comfortable seats were placed directly in front of the panoramic glazing, so that the handling of the aircraft can be observed in the first row. On the third floor is a smoking lounge with ventilation system. The exit to a roof terrace is also possible here, from where takeoffs and landings of the aircraft can be experienced in a more exposed position.





In addition to the transparent interface, which can be shaded by centrally controlled blinds, a generous sense of space is generated with a clear ceiling height of 2.75 m and partially half-height interior walls. Circumferential LED strips at the connection to the ceiling contour and stage the volume. The designed as heating and cooling ceiling space closure ensures the appropriate air conditioning, the supply takes over an air-water pump with MSR technology. Part of the security concept is an escape staircase, fire protection measures, emergency lighting and door monitoring.

Modular Multi-Storey Apartment Building in Bochum, Germany

Client: VonoviaSE
Architects: Koschany + Zimmer Architects KZA
Year: 2018

The close cooperation of a modular construction company, a housing association and an architectural firm is due to the construction of several residential modular multi-storey apartment buildings on the modular principle and in steel modular construction. In a relaxed urban planning arrangement on a newly developed, inner-city plot in Bochum, for example, three Point houses were created, which want to contradict the uniform appearance and repetitive, shapeless image of serial construction.

The Essen-based office Koschany + Zimmer Architekten KZA dealt with the modular construction at an early stage. After a first project in Dortmund, which the architects developed together with the system construction company Alho from Friesenhagen, the cooperation was continued in Bochum. On behalf of the housing company Vonovia, three 4-storey Point houses in the midst of generously designed open spaces were realized. The participants regard the applied modular principle as advantageous for the housing industry as well as for architects and planners.





Planning from the inside out

The Modular Housing Kit developed by KZA and Alho consists of individual module types. These include, for example, a living room and a kitchen, a bedroom with a hallway or a nursery plus a bathroom. From this matrix - a canon of different modules - the apartments are custom-made for the respective location and according to the desired apartment key. Afterwards, the house is created out of this individual mix of apartments. "Normally, architects tend to work in the opposite direction - from outside to inside: there is an urban planning situation from which the building is conceived in its cubature and fitted with floor plans developed from it," explains architect Axel Koschany. "Modular construction is the other way around. It starts with elaborate floor plans - in the end the most important thing for the future residents. Even the most similar apartment types are almost never forced into one and the same cubature due to the different local specifications."

Diversity in modular design and layout

For example, three modular houses, each with 14 residential units, were built in Kaulbachstraße in Bochum in the course of an inner-city rehabilitation measure. As an urban development reaction to the adjacent to the north side 2- and 3-storey neighboring buildings was staggered in coordination with the city. The mezzanine floor jumps back 3 meters on the 4th floor and creates spacious roof terraces. The return could be agreed with the modular design, since this only one module had to be omitted. The systematics of the modular structure remained otherwise unchanged.

The modules are on 17 x 19 m base and 12.5 m high, with 7 one-room, 3 two-room, 2 three-room and 2 four-room apartments, user requirements are covered. The apartments are designed throughout to be barrier-free and wheelchair-friendly. The buildings are centrally accessed via a single-flight staircase and lift system. All apartments on the 1st and 2nd floor have prefabricated balconies, and the apartments on the 3rd floor have rooftop terraces. Arrangement of freestanding Point Houses ensures a varied appearance. The funnel-shaped outer space zones leave room for differently designed open spaces. Green tenants' gardens, playgrounds and other dwellings are planned here.

Profitability factor of prefabrication

Each building consists of 43 room modules. These were manufactured at Alho plant for seven weeks and under ongoing quality controls. At the construction site, the modules were ultimately assembled in seven days per house. The entire construction period of the three modular buildings was - after the ground was prepared - 20 weeks.

"The modular construction can always exploit its advantages if the structural units that are as constant as possible are repeated. That's why we talk about serial modular construction. So that these module types are not built into uniform houses, we work together with architects like KZA. They bring creative input by playing with the building blocks and exploiting their potential in terms of design," explains Michael Lauer, architect at the multi-storey building competence center at Alho.

The projects in Dortmund and Bochum are the first of a series of residential construction projects that will be completed with the developed modular system later this year. The project partners are planning to further optimize the system and to expand new components, such as new module units.

Diversity in modular construction

In Bochum, an exemplary modular construction project proves that series and individuality are not mutually exclusive. On a newly developed, inner-city plot, three modular Point Houses have been created with a loose, urban arrangement and a staggered cubature.

As one of the first manufacturers of prefab modular buildings in steel module construction, ALHO offers sophisticated solutions in multi-storey housing construction. For the housing company VONOVIA, the company is currently (2018) realizing a series of residential buildings based on a modular system. The concept was developed together with Koschany + Zimmer Architekten KZA from Essen. Instead of developing the building out of the urban situation, the process of serial construction begins with the smallest scalable serial element, the module. Depending on the room requirement, these individual elements are put together individually. This is how well-designed floor plans and a large range of cubatures are created with modular prefab units.

The ensemble of the three Point Houses is already the second housing project that was realized together with KZA. It was created in the course of an urban development densification in Bochum. The buildings are four-storeyed and offer space for 14 continuously accessible housing units of different sizes. There is no basement, but all apartments have a sufficiently large storage room and on each ground floor a technology module is arranged. Overall, the Point Houses are made up of 43 room modules. They were manufactured in the factory within seven weeks under strict quality controls at ALHO and installed at the construction site per house within seven days. The total construction time of the three buildings was just under 20 weeks after the ground was prepared with the floor slab.

Contrary to popular belief that modular buildings are boring, the architects were able to make the three residential buildings in Bochum exciting: With the fourth floor projecting back, the design responds to the two- and three-storey neighboring buildings adjoining the north side. At the same time, the staggering of the building cubatures visually revives the facades. In terms of urban planning, the arrangement of the Point Houses, which is rotated towards each other, creates a sense of relaxation: funnel-shaped interspaces that provide space for differently designed recreational areas - from green tenants' gardens to varied playgrounds.

Architect: Sauerbruch Hutton, Berlin
Location: Dratelnstrasse 32, 21109 Hamburg (DE)

Project cost: 37.000.000 EUR

The prefabricated cross laminated timber modules of this student dormitory in Hamburg were developed in close cooperation between the architects of Sauerbruch Hutton, the client and the module manufacturer Kaufmann Bausysteme. A manageable number of design details and the restriction to two module types have made this an efficient as well as inexpensive building possible.

For the time- and cost-efficient realization of the "Woodie" dormitory in the Wilhelmsburg district of Hamburg, the client's decision was made to involve a wood module manufacturer directly after the architectural competition. Following the direct commissioning, Kaufmann Bausysteme, together with the architects and structural engineers at Merz Kley, set about optimizing the area of the apartments.





The definition of the performance limits was essential, which ultimately led to the module builders being responsible not only for module production but also for the directly adjacent trades: the construction of prefabricated concrete floor structures, the production and assembly of all larch wood facades and roof waterproofing. The resulting benefits include fewer and more precise interfaces as well as subcontractor workflows that are clearly tailored to the modular design, ultimately resulting in more quality, fewer defects, shorter construction time, and therefore cost-effective solutions.

All modules were prefabricated complete with interior fittings, finished bathrooms, windows and doors, stored temporarily, packed in a watertight package, delivered to Hamburg just in time, and immediately lifted to the correct position with a crane. An intermediate storage on the construction site was not provided, not least for reasons of space. A maximum of four modules could be produced per day.

The serial production of the modules on a kind of production line brought numerous advantages in terms of accelerated assembly time and a short construction time. Added to this is the fact that assembly processes in workshop conditions and on the ground are generally cheaper and faster feasible than on site. Even more important, however, is the higher quality and precision achievable thereby, without which a modular construction of this type would not have been feasible.

Efficient sound control for timber-constructed prefab modular student residence

On six floors, 100 metres in length and made of solid wood, 371 student flats are strung out in the district of Wilhelmsburg in Hamburg. This makes "UDQ" the biggest timber student residence in Europe and the tallest timber building in Hamburg.

Inspired by the stacked containers in the Port of Hamburg, “UDQ” is made up of prefabricated timber modules that are stacked on top of and next to one other. The whole construction sits on a base of reinforced concrete. Each of the 20 m2 apartments is fully furnished – with bed, bathroom, built-in wardrobe, kitchenette and folding table. Where necessary, single modules can also be combined to create larger apartments.

Effective sound insulation is essential on a project such as this. That is why Getzner was brought on board as experts by contractor Kaufmann Bausysteme GmbH.

THE SOLUTION

To prevent sound transmission between the apartments, the individual modules were bedded on Sylodyn® from Getzner. Timber was chosen as a building material due to its ecological properties and the warm interior ambience it creates. The modules were pre-fitted with Sylodyn® linear supports at the factory for reliable soundproofing.

"Sound mainly propagates through the flanking of the modules. Using elastic bearings, means we have been able to almost completely eliminate sound transmission between the individual modules", explains Hendrik Reichelt, Project Manager at Getzner.
