Tuttlingen, Zürich und Brixen: Cadolto hands over medical buildings turnkey.
Tuttlingen Hospital – Temporary building enables conversion work on the existing building to proceed
Cadolto was awarded the contract for the fabrication and erection of a 3-storey ward building with 99 beds in the second half of November 2016. The scope of work also included excavating and laying the foundations and connection of the modular building to the existing building on the same levels. Cadolto’s bid won the contract against four competitors.
Flexible financing options
A specific feature of this bid: the rental period is 20 months, after which the client has the option to extend for a further 6 months or to purchase the building. The hospital is thus prepared for all eventualities and can react accordingly if the refurbishment or upgrading of the existing building overrun; or if the building is to be used permanently.
Rapid installation, short construction phase
Excavation work started in mid-April 2017 and the foundations were completed by 19 May. A total of 30 modules were delivered ten days later and installed within three days. The building on Zepplinstrasse came into service on 21 July and the construction site could be cleared just seven months from the award of the contract. The short construction phase meant that emissions from the site were reduced to a minimum.
The three-storey building has a gross floor area of 2,045 m². Each floor of the modular building has patient wards (2 and 3-bed rooms), toilets and bathrooms, a nurses’ station, a staffroom, a kitchenette, a storeroom, a consulting and examination room and a waiting area. The stairwell has two hospital bed lifts.
Hirslanden Hospital – Narrow time window, confined construction site
Hirslanden AG has already commissioned buildings from Cadolto for erection at the Hirslanden Hospital in Zurich in the past. Cadolto won the contract for a two-storey extension with a gross floor area of 457 m² against two competitors. Working with schmid schnebli architekten ag, Zurich, this building was designed to dock on to the existing building.
The new extension presented a particular challenge due to the timeframe and also the relatively small construction site. Thanks to the flexibility of Cadolto’s modular construction technology, the new building could be connected without any problems by removing an existing module. The 21 new modules could then be installed and the building was handed over in October 2017.
The new MRT building at Brixen hospital guarantees the long-term future of diagnostics.
The 1.5T Siemens MRT scanner in the turnkey MRT building in the inner courtyard of the hospital in Brixen was in service just 90 days after the award of the contract. The two-storey modular building has a total floor area of 150 m². Cadolto was responsible for the design, fabrication and installation of the extension through to turnkey handover.
Due to transport via the Brenner Autobahn and the restricted space on the site, the building was prefabricated in four modules of reduced size and weight. As bedridden ITU patients are also to undergo examination, the demands on the building and medical technology were extremely high. The Siemens 1.5 T MRT scanner was lowered into the building via an opening in the roof after fabrication of the building and all technical facilities and installed within the RF shielding.
Benefiting from the modular construction system
The existing structure in the inner courtyard severely limited the use of conventional construction techniques and would have had a seriously adverse effect on patients in the neighbouring buildings. The benefits of Cadolto’s modular construction system, maximum prefabrication, speed, high degree of flexibility and adaptability to individual requirements, could be used to optimum effect in this situation. This resulted in low emissions from the construction site and a reduction of the construction time to 3 months.
Use of a 1,000 tonne mobile crane
In contrast to other construction projects, a real heavyweight had to be used here: a 1,000 tonne mobile crane. As the new MRT building was to be installed in the inner courtyard of the hospital, the modules had to be lifted by this special crane some 120 metres wide from the low loader in the street over the existing building into their final location.
