    TENDER DESCRIPTION

    The existing gas-insulated medium voltage switchgear (MV) of UW SEM is to be renewed due to age. The request is addressed to general planners for structural/technical construction services according to SIA 102/103/105/108.

Due to the renewal of the electromechanical equipment and the overall condition of UW SEM, structural or technical construction measures must be implemented. This includes, among others: - Repair of the structural fabric and upgrading for new use - - Renewal of building technology (ventilation, climate control) - Renewal of building services equipment and electrical installations - Renewal of lighting systems including emergency lighting as well as cabling and cable trays. - Fire protection upgrades including structural fire protection
