Stations for intercity transport services are a construction challenge as they are usually located in areas with a high density of both road and pedestrian traffic. Therefore, precast solutions are especially convenient for these cases, as they significantly reduce the execution times and occupation of intercity areas.

After defining the station and the interior elements such as stairs, platforms and boarding areas, loads are calculated to design the precast elements properly.

There are basically two methods for assembling precast elements and for building the station:

  • In the first method, after building the concrete walls housing the station, the excavation required for the station is carried out, then the precast elements are installed and so the station is built from the bottom of the shaft to the outside.
  • The second method would be the opposite: the roof of the station is built in the first place, leaving enough space to later remove the assembly machinery inside, and then the structures inside are assembled. As intermediate floors are completed, the excavation of the level immediately below is carried out.

The second option significantly reduces the impact of the work on both road and pedestrian traffic.

PACADAR has a large experience in this type of construction work, as it has successfully carried out major works, which involved both manufacturing and assembling components. Palmaret station of the Valencia Metro, the interchange station of RENFE in Can Roc, or the stations of the line Madrid-Villaverde, are some examples of our track record of completed projects.

PACADAR uses elements such as Pi-shaped beams of large depth which guarantee the load bearing strength both on surface and intermediate floors. Likewise, PACADAR uses hollow-core slabs with a depth of up to 63 cm for horizontal surfaces.

Apart from underground stations, PACADAR also provides a wide range of solutions for stations of elevated metro railway systems, as well as for train lines. These cases are less complex than intercity stations. Construction periods are shorter, and so precast elements can, for example, be transported by the same rail as the construction work progresses, and so the stations are completed at the same time as the railway line.
