Hotel Marques de Riscal, Elciego, Spain
Optimal adjustment to very unusual building geometry
Frank O. Gehry, designed this luxury hotel complex for the renowned “Marques de Riscal” brand in the Rioja wine-growing area. It is comprised of several cuboids which are pushed into one another. The dominant feature is a bold roof structure with an almost free-floating titanium skin that optically accentuates this most extraordinary construction.
From the construction of the foundations right up to the assembly of the 1,800 m² titanium roof area, PERI supplied the formwork for the walls and slabs, shoring systems as well as safe working platforms. Due to the centralised planning and processing of all formwork and scaffolding assignments, the systems could be optimally co-ordinated which led to extremely efficient construction progress. At the same time, the all-round utilisation of the PERI UP Rosett modular scaffold system provided considerable on-site advantages: as shoring for formwork operations and afterwards as working scaffold for the roof assembly, all scaffolding tasks could be carried out cost-effectively with a single system.
Using TRIO panel formwork, the three massive, 16.50 m high reinforced concrete cores could be concreted in one pour. The areas with rounded wall sections were smoothly executed by the experienced formwork crew using polygonally-arranged TRIO elements. Construction of the slender reinforced concrete columns with different cross-sections was carried out with TRIO column elements.
The almost 55 x 20 metre large twisting reinforced concrete slab was constructed as one single casting segment without any concrete joints. SRZ steel walers as well as GT 24 formwork girders formed the slab formwork for the up to 1.30 m thick bridgelike slab cross-section. Articulated couplings also provided friction-locked connections between the steel walers positioned at the vaulted transitional areas between the varying slab thicknesses. For supporting the formwork and transferring concreting loads, a stable, spatial shoring construction was assembled using PERI UP Rosett.
As the assembly of the props and steel girders for the roof construction progressed, erection of the spatially-arranged PERI UP Rosett working scaffold also kept pace. In spite of the irregularly curved and twisted roof surfaces, problem-free assembly of the modular scaffold system could be carried out. When putting down and stacking the vertical standards, the special shape of the scaffold node prevented the equipment from rolling away and thus causing damage to the expensive roof surface.

“When realising this complex project, PERI proved itself to be a very competent partner. Within the shortest possible time, we received workable solutions. Also, the supply of large quantities of required formwork and scaffolding systems took place at very short notice. The PERI UP modular scaffold allowed optimal adjustment to the complicated building geometry.”
