Austria – Substation construction work – (ProVia-ID 161711) UW Landeck; UW Landeck - Baumeisterarbeiten

The subject project involves the construction of a new substation at the same location with one-third de-energisation capability and the use of a mobile substation. The new building consists of a 15-kV switchgear building and maintenance/ scaffolding space, a 15-kV metal-enclosed installation, a 110-kV outdoor switchgear with three 110/15-kV transformers, a 15-kV switchgear frame with cable collector including all ancillary facilities. The Landeck substation will be renovated on-site in 2 construction phases. During the 1st renovation phase, one third of the existing installation, a mobile substation and the existing overhead line switchgear will remain in operation. At this time, the 110-kV railway power line Pettneu 2 – Ötztal 2 will be re-routed at the overhead line mast Nr. Ld 2. The front part (U3) and the middle part (U2) of the installation will be taken out of operation. After the reconstruction of the front 2 thirds (U3, U2) of the outdoor installation and their commissioning with the new 15-kV installation, including the new switchgear frame, the rear third (U1) will be newly built. In this 2nd renovation phase, the 110-kV railway power line Pettneu 1 – Ötztal 1 will be re-routed at the overhead line mast Nr. Ld 1. The new 110-kV outdoor switchgear is designed as a double busbar system with top-mounted busbar and 2 longitudinal sections with coupling in line-longitudinal construction. The transformers will be delivered track-bound to the installation. The entire grounding system for all installation parts will be erected according to the valid regulations and standards, taking into account the ÖBB regulations and the technical specifications for switchgear. The substation building corresponds to building class 1 according to the valid OIB guidelines. The surface water drainage of the paved areas, including the roads, will be carried out via infiltration on the owner's property. The roof water will be directed into a new infiltration shaft to be constructed and infiltrated on the owner's property. No permanent workplace is planned in the new premises. The following existing installation parts will be renovated: 15-kV substation switchgear frame, complete 110-kV outdoor switchgear, substation track, substation building. All work is to be carried out taking into account the existing infrastructure, the applicable standards and the project-specific requirements. The planning services include the creation of layout and section plans, static proofs, reinforcement and formwork plans as well as performance specifications for the later tendering of the construction services.
