The employers' association Seopan estimates that at least €52.838 billion will be needed in the next decade. Of this total, €34.443 billion would be allocated to new construction and modernization.
The employers' association of builders and public works concessionaires Seopan has calculated that the minimum investment needed in Catalonia over the next ten years amounts to €52.838 billion. According to elnacional.cat, the report does not review what has already been done, but details which works need to be modernized, maintained, or constructed from now on. Part of this bill will fall on the Spanish Government, the Generalitat, and, in some cases, on concessionary companies.
Of that figure, €34.443 billion would go to new infrastructures and the modernization of existing ones, while €18.395 billion would be allocated to maintenance and conservation. Two-thirds of this latter block correspond to water, an area that often remains outside public debate because its problems are less visible than railway delays or traffic jams.
Transport accounts for the highest allocation, with €21.973 billion. Railways absorb €14.787 billion, with €5.359 billion for the Barcelona Orbital Line and €2.614 billion for actions on the R9 Rodalies line. The extension of the L3 metro line, between Zona Universitària and Sant Feliu de Llobregat, would cost €1.274 billion, and the Collserola tunnel €900 million.
For roads, the report forecasts €2.883 billion, of which €1.064 billion would correspond to the State for the A-7 and A-2 highways. For the AP-7, which has generated complaints about its condition in recent months, €162 million is reserved to increase its capacity. In ports and airports, the figure rises to €3.260 billion, with €730 million for access to the port of Barcelona and €1.760 billion for the expansion of El Prat airport.
The water sector needs €9.530 billion. Within this, €2.900 billion would be allocated to adapt sanitation and purification to the new European directive, of which €1.900 billion would go to Catalonia's internal basins. For stormwater retention tanks, the report sets €698 million, and to improve the Ter-Llobregat network, operated by Aigües Ter-Llobregat, another €388 million.
For the reader in the province, the figures translate into works that would reach their daily lives: fewer disruptions in Rodalies if the R9 actions are completed, smoother access to the port and airport, and water and purification networks prepared for heavy rains. The document sets the horizon at ten years but does not detail an annual bidding calendar nor allocate the funds among administrations in a closed manner.
