Elegant 3D Waves In Steel &#8220Unbuildable Facade&#8221 Completed

With its oval kind and a metal façade that nearly appears to be flowing, the primary creating of the InterContinental Davos Hotel has grow to be an unmistakable new landmark. The undulating envelope wraps itself tightly about the structure, top to an interplay between open and closed surfaces which appears distinct from every single angle.

Oliver Hofmeister from Munich-based architects Oikios worked out the underlying notion for the supple however incisive external kind even though really in Davos. The official name of the parcel of land on which the hotel stands is “In der Stilli” – a name that reflects the tranquil, sheltered surroundings. That peacefulness and safety also had to be expressed in the architecture of the creating. A pine cone with its smooth scales from the nearby forest supplied yet another source of inspiration. So that is how the hotel got its curving oval envelope.

Hofmeister was capable to persuade leading-notch partners to join him in realising his “organic” design and style idea. These partners integrated designtoproduction, accountable for the complicated digital modelling of the façade surfaces and the parameterisation of the façade geometry, structural engineers Wilhelm + Companion and seele, known as a specialist for extraordinary façade styles. Functioning closely with each other, this group developed and constructed an innovative façade with 3-dimensional, curving spandrel panel components. Observed in the light of the price range accessible and the high top quality demands, numerous experts had 1st deemed the façade “unbuildable”.

It was seele who contributed what was probably the most surprising notion: creating the spandrel panel components from steel rather of the aluminium originally envisaged. Taking this as its starting point, the team created a design for the laser-cut primary and secondary ribs which is primarily based on a square. It is this supporting frame – with a main grid identical for all elements – that is accountable for the 3-dimensional curvature. The frame is covered on all sides with sheet steel just 3mm thick, which with its champagne-coloured metallic coating types the visible surface of the façade on the finished building.

The steel building proposed by seele proved to be much less pricey than aluminium and less susceptible to alterations in length due to temperature fluctuations. Mostly, even so, it enabled the intended, original geometry to be realised with great precision, minimum tolerances and the smooth surfaces specified in the design short. At the identical time, the ribs of the supporting structure permitted a completely new concept for the structural fixings and the transfer of the loads to the floor slabs at each and every storey.

The challenge that faced the group in the production and erection of the elements was mastering the logistics for 791 spandrel panel elements – more than 62,000 individual pieces including the dome crowning the hotel. Such numbers can only be managed by automated procedures in style and the preparation of fabrication drawings. All the architects’ specifications had been incorporated in a parameter-controlled script by designtoproduction. The 3D model of the façade geometry was adopted by seele and imported into applications, some of them created by seele, for producing the fabrication drawings and laser-cutting data. But not only that, the 3D information could also be employed by Wilhelm + Companion in Stuttgart for their detailed structural calculations.

Every single spandrel panel element is special. However, every single has an identical, square, steel rib construction, so the elements could still be produced really economically according to a modular system. In terms of the manufacturing precision, the individual components (in common sizes of about 1.6 x 4.5m and unique sizes up to 14.6m extended) are comparable with pieces of furnishings – and were handled with equivalent care! Every single façade element had its own bespoke transport frame so that it could be safely transported to Davos by road from the production plant in Plze? in the Czech Republic.

Façade specialist seele was able to draw on the preparing and investigation perform of the style group. Amongst developing the vital mock-up in the option steel design and style and the final handover of the façade in October 2013, the whole project, involving detailed design and style, production and erection, took only 2 years.
