The Sarrià Road Sports Field, owned by the Real Club Deportivo Espanyol of Barcelona, with a legal capacity of around 15,000 spectators, was insufficient to comfortably contain the large number of people who wanted to witness the football competitions that were held there. Therefore, for a long time, the expansion of the grandstand stands had become essential. In the alignments of the sector approved by the City Council on November 30, 1953, the possibility of permanence and expansion of Sarrià Road Sports Field was foreseen so that a legal capacity of around 35,000 spectators would be possible, leaving the venue of the Sports Field surrounded in almost all its perimeter by streets. At the request of the Board, a general preliminary project was drawn up that would allow the development of the works in various successive phases and in accordance with the economic possibilities of the club. The first phase corresponds to the expansion of the main grandstand, which is the object of the current project. DESCRIPTION - The works essentially consist of adding a cantilevered upper grandstand over the existing one, removing the current metallic structure canopy and extending the depth of the stands by 12 metres. The transversal profiles have been carefully studied to obtain perfect visibility for all spectators, both in the numbered seats and in the standing seats. The stands are divided into a high stand, a low stand and the general stands. The lower tribune comprises the lower section of 6 rows of uncovered numbered seats, while the upper section with 12 rows of covered seats is called the tribune, in which the presidential tribune and the authorities' market are located, flanked by its front and sides by 21 boxes that also extend behind the seats in the main tribune, forming boxes with 6 and 8 seats. For the access of these towns, the following vomitorium and stairs have been planned: 6 2-metre vomitorium and 2 3-metre staircases, 18 metres in total. The lower and main stands are separated by a 1.20-metre-wide corridor, into which the vomitorium open, and in a transversal direction by 1-metre-wide stairs, separated at a maximum distance of 12 m. The terraces of the stands are 80 cm wide, of which 40 are for numbered seats and the rest for passage. The width of the seats will be 0.50 m per viewer. The high tribune also includes two different sections: the upper tribune and the stands, which in turn are subdivided into lower and upper. The upper grandstand will consist of 6 rows of uncovered numbered seats and forms a cantilever over the main grandstand, 9.50 metres. The stands are made up of two sections of 8 and 14 rows of unnumbered standing seats. For the service of these localities, the following vomitorium and stairs are projected: upper tribune, 8 2 m. stands, 10 vomitorium of 2 m. In the upper tribune there is a distribution corridor 1 m wide, and in the stands another central aisle of 1m after the 8th row and another top 2 m after the second flight of stands. The seating locations are calculated to be 0.60x0.50m wide and leaving stairs of 1 m, with a maximum separation of 11 m. STRUCTURE. - The structure of the new grandstand is projected in reinforced concrete, forming porticos with two sections and a 9.50 m cantilever, attaching the new structure to the existing porticos of the current one, leaving an expansion joint between them, so that they are totally independent. The separation between porticos is 7 m of the line of the façade structure and radially converging according to the curvature of the current grandstand. The porticoes are locked by transversal girders and by the ceiling slabs of the floors and mezzanines described. The structure is projected by slabs of reticulated reinforced concrete, the stands being formed by ribs of reinforced concrete and slabs of the same material that complete the bracing of the porticos. The entire structure has been meticulously calculated for overloads of 500 kg per square metre. To avoid the cracks produced by the hardening retractions, two expansion joints have been planned in a transverse direction, coinciding with those currently existing in the current lower stand.
