Janeiro de 2004
A PECS foi responsável pelos projectos de estrutura e fundações e de todas as especialidades do centro de estágio e formação do Sport Lisboa e Benfica.
Além do desenvolvimento dos projectos foi também responsável pela sua coordenação e pelo acompanhamento dos respectivos licenciamentos administrativos. Esta infra-estrutura desportiva integra sete edifícios e cinco campos de futebol.
Maia Shopping Center
PECS was responsible for the structural and foundation projects and for all the specialties of the Maia Jardim Shopping Center.
This building is intended for commerce, housing a Continente hypermarket, with an adjacent shopping area and a car park. It has 4 floors, with the -1 Floor buried for parking, technical areas and deposits; o Floor 0, semi-buried destined to parking and to the commercial area; Floor 0A, raised floor for part parking, part for office areas and part for technical areas and Floor 1, roof, part for parking, part for technical areas and part for green areas.
The building is prepared for future expansion, with an implantation area of about 30 000 m2. The high length of the building in both directions (200x200 m), forced the introduction of expansion joints, in order to circumvent the retraction effects. Vertical joints are duplicated in all joints. Even so, the 4 structural modules that make up the building have a length of about 100 meters, in both directions.
The structural solution involves the use of solid fungiform slabs with pyramidal capitals and maple beams, however, there are areas on the 1st floor where pre-stressed beams are used to overcome larger spans. For the floor 0 and floor 0A, in the area intended for parking, a structural solution of solid fungiform slab in reinforced concrete, 0.22m thick and with pyramidal capitals whose height varies between 0.57m and 0.22m was adopted . In its contour, the slab supports border beams or retaining walls. The structure of the rest of the 0 floor is similar to the previous one, but the thickness of the slabs is 0.25m and the capitals vary between 0.25m and 0.60m. In general on floor 1 the solution is identical to the commercial area on floor 0. However, above the hypermarket the spans are often 16 meters long, so a solution using solid slab supported by reinforced concrete beams and beams is used. pre-stressed. The heights of the beams vary between 1.20m and 1.60m.
The vertical elements are arranged in a general grid of 8 x 8 meters, with some exceptions, namely at the level of floor 1 where the clearances reach 16 meters. The resistance to horizontal actions is guaranteed mainly by the cores, resistant walls and porches existing in the interior and periphery of the building.
Given the characteristics of the terrain, the foundations of the buildings were made either directly by means of shoes, or indirectly by means of piles molded in the land. The connection between the foundation piles and the rest of the structure is made by means of foundation blocks with a height between 0.90 and 1.10 m and dimensions in plan varying according to the situations.
PECS was also responsible for the design of the hydraulic installations for the entire building, as well as for the coordination of the other specialty projects, which were carried out in association with another office.
The hydraulic installation projects carried out covered the fire water networks, including the respective pumping stations, rainwater networks, domestic water networks, fatty water networks and groundwater drainage networks. A rainwater reuse system was implemented for use in the building's sanitary facilities. The rainwater networks were designed using the PLUVIA system, in order to be able to overcome the large distances involved without the need to use slopes in the pipes.
