Two tone metal building

Construction with metal structure

In 2017, the color study of the building of Faculty of Architecture, Urbanism and Arts (FAUA) was carried out in order to recognize the different underlying pictorial strata to know the color palette used in the painting that correspond to the FAUA at the long of the time. This has allowed us to know the different uses and styles used, as well as techniques and materials used. On the other hand, this type of prospecting has allowed defining the conservation status of certain strata. The use of prospecting techniques, such as the elaboration of stratigraphic samples allow to investigate and study the real estate as a historical document and in turn leave a vestige on the changes that have occurred at the aesthetic and stylistic level.

For the elaboration of the present research, the analysis of the different spaces of the building of the Faculty of Architecture, Urbanism and Arts of the National University of Engineering (FAUA-UNI) has been carried out. In this way, the architectural ensemble and the relevance of the architectural elements that make up each area have been evaluated in order to be able to project and define the specific places where the stratigraphic coves would be made, since they must be representative so that the chromatic projection extends to the architectural ensemble. Once the stratigraphic coves have been made at the selected points, the chromatic interpretation and comparative identification with the standardized color charts is carried out, in order to identify each chromatic stratum with a specific color and define which tones are predominant in each cove. In addition to the chromatic analysis, the coves will provide relevant information on the different chromatic uses in the history of the FAUA.

Prefabricated metal frame houses

Wood is a material that undergoes gradual wear and tear over time, much more so than a concrete structure. The houses with wooden structure are less stable, since the wooden beams can move slightly causing slight alterations in the general structure of the building.

It is very common to detect these flaws when works or reforms are carried out in private homes. At the moment of demolishing a partition wall or a false ceiling is when the problem comes to light, and it is decided to proceed with the repair or reinforcement of the solivería.

In this project, in a house with a wooden structure in Donostia-San Sebastian, we placed several metal beams under the wooden floor, helping to reinforce the entire wooden structure of the house.

In the image on the left we discover the worn wood, once the false ceiling was opened. Next, we placed several props to support the weight of the wooden beam and place the metal beam in a more comfortable way.

Steel-framed buildings

Based on these premises, we were faced with the challenge of building an 8-story multi-family vertical housing construction, consisting of a ground floor and 7 apartments, on a site where a deteriorated three-story building was previously located.

The building is located on the sidewalk level, from which there is immediate access to an open floor where parking and reception are located. On each of the subsequent levels there is a 72 m2 apartment with 19 m2 of terraces and balconies.

In order to achieve lighting and ventilation in all the spaces, it was decided to take the maximum height allowed for each of the mezzanines, which also allows to provide spaciousness to the interior spaces and open the views to the outside, allowing from each of the apartments to have a different panorama of the city and its walkways.

Metal frame houses advantages and disadvantages

COST ESTIMATION:The cost of this system is determined by the finishes to be used.  For a standard solution of brick-colored ceramic pieces and 8cm of rock wool thermal insulation, the rehabilitation of a facade using this system has an approximate cost (including the cost of rental, assembly and disassembly of scaffolding) starting at 118€/m².HEATING SAVINGS:VALUATION:The ventilated facade is one of the most technically complete options for the rehabilitation of facades. Although the initial investment cost is somewhat high, the analysis of the investment in the medium term confirms its absolute competitiveness with respect to traditional plastering systems or monolayer (systems 3 and 4).

The sate system (external thermal insulation composite system) or etics (external thermal insulation composite systems) consists of placing thermal insulation sheets adhered to the wall on the external face of the facades. The usual fixing is usually done by means of adhesives and mechanical fastening. The most common panels are made of expanded polystyrene and mineral wool sheets are becoming more and more common. The insulation is protected with a coating consisting of one or more protective layers, one of which is reinforced with a mesh. The external coating is applied directly on the insulating panel.CONSTRUCTION:
