Short construction time thanks to NOEtop large panels
NOEtop large panels result in short construction times for affordable housing in Munich
A residential complex with 69 housing units, a basement garage and several shops stands on a plot with an area the size of a small football pitch in Munich. The complex was built with the help of systems supplied by NOE-Schaltechnik, Süssen, Germany.
Almost unnoticed by the Munich public, a small urban quarter in
Schwabing-West has blossomed into an up-market residential and
business district from its origins as an obscure outlying suburb.
In addition to several residential buildings, the area now has
shops, a multi-generational housing block, a school and much more.
Part of this development is being constructed on behalf of GEWOFAG
Holding GmbH, a housing association based in Munich. With around
37,000 housing units, GEWOFAG is one of the largest landlords in
Munich and focuses on offering homes to people who would have
little chance of finding accommodation on the open housing market.
With the concept "Wohnen im Viertel" (Local Living), a further aim
of the housing association is to enable older people and those
dependent on care to live independently in a safe
New affordable housing
As part of GEWOFAG’s contribution to the provision of affordable housing, the development in Isoldenstrasse, at the corner with Rümannstrasse, will have 69 housing units, a basement garage and several shops stocking everyday groceries and goods. The plans place great emphasis on providing a good quality of living. Many of the apartments have been designed to comply with the DIN 18040 requirements for barrier-free accommodation. The whole building meets the KfW-55 standard for energy efficiency. To help achieve this, the building is constructed in reinforced concrete with an external thermal insulation composite system (ETHICS). The concrete structure was built by Emil Mayr Hoch- und Tiefbau GmbH, a contractor based in Ettringen, Bavaria. In less than just 20 weeks, the site team constructed 60 000 m² of wall and 19 000 m² of ceiling in reinforced concrete.
Emil Mayr Hoch- and Tiefbau GmbH chose to use NOEtop for the walls. This is an extremely robust wall formwork system, which has an allowable concrete pressure of 88 kN/m² and is easy to handle. Integral bracing in the large-area panels allows a free choice of tie bar positions. It can also be used without problem as single-sided formwork. NOEtop is available in many different sizes (height 0.66, 1.32⁵, 2.65, 3.31 and 5.30 m; width 0.25 to 5.30 m), almost all of which were used on the Munich project. For the most part, Emil Mayr used the NOE XXL panel with dimensions of 5.30 x 2.65 m. For the basement and the above-ground storeys, the panels were used side-on, for the ground floor they were end-on. The panel has over 14 m² of formwork surface and is one of the largest on the market. These panels were mainly used for the basement and ground floor, i.e. where walls up to 5.50 m high had to be formed. Because the basement was constructed in waterproof concrete, the maximum length of wall that could be poured in a shift was 15 lin m. All the more helpful, in this case, was the casting sequence plan drawn up by the NOE engineers specifically for this site. Using the plan, the site manager was always aware of how many panels needed to be retained on site at any time and which elements could be combined with one another most efficiently.
The Emil Mayr Hoch- und Tiefbau GmbH site team's work on the Munich project was made easier by the use of NOEtop stripping corners. The stripping corners consist of articulating units specially designed for casting corners in parts of buildings where space is restricted, such as inside lift shafts. After release from the concrete surface, the footprint of the internal formwork unit can be reduced by about 4 cm each side by the upward pull of a crane. The internal formwork does not have to be dismantled, which makes stripping considerably easier. After moving to the next position, the crane rope is reattached and a further pull upwards returns the unit to its original cross-sectional dimensions, ready to form the next pour. In a total of eight lift shafts, each of which extended over five storeys, the NOEtop stripping corners proved to be a great help in keeping up with the rapid tempo of the programme.
To erect the ceiling formwork as quickly as possible, Emil Mayr Hoch- und Tiefbau GmbH also called upon concrete formwork from NOE-Schaltechnik and used, among other things, NOE H 20 deck formwork. The many beams and slab projections in the basement and ground floors presented a sizeable challenge to the Munich site staff, but the system's great flexibility of use meant this potential problem was quickly overcome with NOE H 20 deck formwork. The contractor was then able to complete the ceiling slabs quickly and efficiently.
This was the first time Site Manager Oliver Beer and Foreman Maik Haussner, who ran the site for Emil Mayr Hoch- und Tiefbau GmbH, had worked with NOE formwork and they were very satisfied with the systems and the service. Oliver Beer says: "Using NOE formwork required hardly any initial training. Although the system was new to us, the work progressed at a brisk pace." His colleague Maik Haussner adds: "And the service from NOE was very good; the formwork was supplied quickly. Whenever there were questions, an expert advisor was always available."
It is good when a company receives such positive feedback following a successful partnership.
