Topographical, geological and geotechnical inspection: The topographical inspection consists of the surveying of the terrain and the production of a graphical representation of it. The composition and structure of the terrain is checked during the geotechnical and geological inspection. These calculations are very important for the correct planning of the installation.
Pegging: This procedure is considered to be very important. Reference points are fixed on the ground that will be useful for the next steps (excavation and reinforced concrete works).
Excavation: Depending on the consistency of the ground on which the system is to be installed, various machines, such as heavy-duty excavators for large-scale excavations or walking excavators for inaccessible areas, are used.
Reinforced concrete work: The basic structures of the installation, such as the foundations for the stations, the support towers, the duty rooms or the parking buildings, are partly or completely made of reinforced concrete.
In the meantime, the availability of standard elements, like the roller batteries or the load-bearing structures for the stations, is checked. The mechanical and electrical project planning, the production and acquisition of specific elements, such as the drive, the rope or the support towers, is also carried out at this time so that all the components will be available ready for assembly.
