Stage machinery Studioscenen

The tender contest is for the replacement of the upper stage machinery at Studioscenen at Dansens hus in Oslo, according to the Technical Specification. The current system is nearing the end of its lifetime. In addition, the system is limited in functionality, lacks positioning and load monitoring, and does not meet the current security requirements. Other targets for the upgrade include: * Several options/points for suspension. * Simple changes and shorter restructuring time between productions. * Better working environment. It shall not be necessary to use a lift to move hoists or suspension points. * Possibilities for movement during performances. The project consists of two parts: 1. Construction work consisting primarily of changes to the steel structure in the roof as well as moving building technical installations. 2. Engineering design, production and installation of the stage machinery. Each project part is a turnkey contract where the turnkey contractor has the full responsibility for engineering design, planning, production, installation, testing, training and documentation. This competition is for project part 2, delivery of the stage machinery. The planned solution is based on a system with traditional stage features with the addition of point stretches. There will be up to 16 stage covers, 2 side covers and 4 courts for a variable number of concentrated stretches. The pulley rods are to be carried by four steel wires or steel band. A steel construction dedicated to the stage machinery will be installed by another contractor. The existing HEA beams will be disassembled. Eight new beams will be assembled in the hall ́s longitudinal direction, placed so that four are used for stage stretches and four for concentrated stretches and/or other temporary equipment. The machinery will be located above the balcony on one side of the stage. A dividing wall will be set up to create an engine room and screen for sound between the winches and the stage. The entire system, including the pulleys and control system with security functions, shall be constructed in accordance with the norm NO-EN 17206 "Event technology, machinery for stages and other production areas, Safety requirements and inspections". The installation shall fulfil relevant EU directives, including directives for machines, low voltage and EMC. A comprehensive description of the delivery is in annex 1095-922 "Technical Specifications".
