The Regional Art Museum was made with a human hand shape, molded in all the elevation of the building at its own scale, granting a unique and surprising image, besides it constitutes, by itself, a challenge in the constructive process of the building façade.
The façade was made in apparent concrete, pretending an identical to bronze color finish and a glassy look. The colored concrete is obtained by mixing metallic oxide based pigments, the color used in the building is obtained with iron oxide.
To achieve the glassy look in the concrete was thought to use vitric rock aggregates or add crushed glass, having in mind the implementation of measures to avoid alkalis-silica reactions that could occur from using this materials.
The hand shape inlayed in the concrete has relief and a geometry that resembles a human hand magnified about 100 times. This shape will be replicated along the building but with different orientations. To ease the construction of the walls, only the exterior faces were granted irregular shapes, being that the interior walls are completely plane.
The constructive process proposed for these walls is based in the collocation of a complete hand shaped mould fixed to the exterior panels. The panels and the mould are immobilized by a secondary supporting metallic structure. After these elements are mounted, the wall will be covered with concrete by phases from the interior of the building, being that in each phase will be necessary to previously proceed to the placement of the respective array and interior panels. The mould geometry will always be the same for all incrustations; only the angle with the vertical axis will vary.
About the services, the challenge we proposed ourselves was to briefly construct an efficient building in an energy point of view and optimized water usage.
