The work consisted of executing the construction of, and complementary town planning works on, the new University School of Industrial Technical Engineers of Donostia-San Sebastián.
The building houses Laboratories, Offices, Lecture Rooms and General Services (Dean's Office, Administration and Secretary's Office, Caretaker's Office, Archives, Cleaning, Bar-Dining Hall, Reproduction-Publications, Students, Halls, Media and Library).
The intended composition of the premises is the mixture or union of four volumes joined together by a fifth that comprises the general areas where people walk or sit, and absorbs the interstitial spaces left by the other four volumes.
The four volumes are:
The curved blocks, A and C, are faced with cenia limestone and their joinery is of anodized aluminium.
The prismatic blocks, B and D, are basically of sheet aluminium, to offset the stone.
Finally, volume E, which is the nexus that joins up and articulates the other four, is of glass curtain walling to leave this intended composition on full display.
Turning now to the CONSTRUCTION SYSTEM, its main features were:
Foundations and structure
The foundations are based on driven prefabricated piles that penetrate down to the bedrock.
A reinforced floor slab ensures the watertightness of the foundations.
The structure is of reinforced concrete, both in the pillars and in the stair slabs, lift walls and load-bearing walls.
The horizontal structure was executed with waffle slabs of voided concrete cornices on the façades, etc.
All the roofs are inverted flat roofs, and some of them are designed to be walked on (access to rooms with installations or the roof terrace above the library).
The technique adopted was to pump cellular concrete onto the load-bearing roof deck, and lay waterproofing of a double asphalt membrane, sheets of rigid extruded polystyrene foam and filtering geotextile felt.
On top of these, in the case of the roofs designed to be walked on we fitted load-distributing plots and reinforced hydraulic tiles; and in the case of the other roofs, we spread loose smooth pebbles to a minimum depth of 6 cm.
Basically we used three types of closure:
The building has the following installations:
