Bahnstadt Heidelberg - One of the largest urban development projects in Germany to become a reality.The premium urban districts “urban element” and “urban view” in the Bahnstadt area of Heidelberg are being created using PASCHAL formwork and shoring systems.
Ed. Züblin AG / Mannheim region and SFB Karlsruhe have been commissioned by LBBW Immobilien to construct the high-quality multi-storey residential buildings at passive house standard.
Homogeneous reinforced concrete building shells
From the underground garage foundation to the green reinforced concrete roof slabs, the building shells of "urban element" on the W1.2 construction site and "urban view" on the W1.1 construction site will be constructed in the same manner - as entirely reinforced concrete building shells.
Ed. Züblin AG is working together with the formwork and shoring experts PASCHAL as a reliable partner to ensure rapid construction progress to satisfy the highest of standards.
Less is more, when it is used intelligently
As a result of the limited space available, there are only small logistics and storage areas at the construction sites. PASCHAL was therefore guided by the laws of minimalism during its pre-planning for the construction company carrying out the work.
Ed. Züblin AG required just 250 m² of the Modular universal formwork for building the foundation and the reinforced concrete beams for the five "urban element" apartment buildings on the W1.2 construction site where the shell construction has almost been completed. 725 m² of the LOGO.3 wall formwork system were used for the elevator and staircase walls using in-situ concrete. 5 units of the "Grip" adjustable column formwork were sufficient for the reinforced concrete columns. Temporary support for the filigree slabs was provided using the "PASCHAL Deck" system. 120 t of slab material was delivered by PASCHAL to the construction site for this purpose. GASS, the aluminium shoring system, was planned to provide support in areas with larger clear heights.
PASCHAL adjustable props and supports were used for the perpendicular fixing of the panel walls. Precast wall adapters were used for the safe and fast filling with concrete of the panel walls. The LOGO concreting platform can be attached easily and safely in the gap between the panel walls for this purpose.
Practical and efficient: Just four formwork systems - Modular, LOGO.3, Grip and Paschal-Deck - and two supports/shoring systems were sufficient to complete the building shell construction for the 90 underground parking spaces and 90 apartments in the planned period of time.
Almost 100% of the W1.2 construction site has been built upon. As there was very little space for logistical and storage areas, PASCHAL developed a minimalistic material system in collaboration with Ed. Züblin AG.
Perfect work preparation planning
Perfect work preparation planning and strict compliance with the delivery quantities and delivery times for the formwork and shoring materials made it possible to complete the building shell construction for the 90 underground parking spaces and 90 apartments in the planned period of time using just four formwork systems - Modular, LOGO.3, Grip and Paschal-Deck - and two supports/shoring systems. The size of the apartments varies between 45 m² and 190 m². The total residential area comes to 8,300 m².
In rapid succession
After the building shell constructions for the five "urban element" apartment buildings on the W1.2 construction site were essentially completed by Ed. Züblin AG, the construction team started immediately with the building shell construction work for "urban view" on the W1.1 construction site at the end of September 2017. Due to the processes being well co-ordinated between Ed. Züblin AG and PASCHAL, the building shells were also continued here using the same PASCHAL systems as were used on construction site W1.2.
Background information on one of the largest urban construction projects in Germany
The Bahnstadt, the name of the new urban district with an area of around 116 hectares is larger than the historical centre of Heidelberg. 5000 people are to live here in the future and 7,000 people will work here.
As with all of the residential buildings in the Bahnstadt area of Heidelberg, "urban element" will be built to meet the passive house standard. A thermally insulated building shell and windows with triple glazing contribute towards a low level of energy consumption. Furthermore, solar energy and the heat emitted by persons or technical devices regulate the room temperature. The inhabitants are supplied with dust and pollen free fresh air thanks to a controlled ventilation system with heat recovery.
