Introduction Most of the stage machinery systems at the Odense Teater are being replaced. A few systems will be partially replaced and overhauled. The stage machinery consists of overstage and understage machinery systems. In addition, the theatre will be equipped with a new stage machinery control system, which will control all stage machinery systems. The following text does not contain any detailed technical information. It is intended to give the bidder an overview of the scope of the work in order to spark his interest and to give him the opportunity to assess whether he can offer his services within the specified period, taking into account the scope and complexity of the systems described. Dismantling The theater's existing systems must be dismantled and disposed of. This includes motor drives, mechanical systems, steel construction, electrical infrastructure and the wooden stage floor. Stage machinery The overstage machinery systems to be dismantled currently include the following systems: 22x Counterweight fly bars 8x Powered fly bars 2x Powered lighting Bars 1x Winch drive of the safety curtain The understage machinery systems to be dismantled currently include the following systems: 6x Orchestra pit elevators (scissor lift) 1x Turntable The associated infrastructure such as wire ropes, pulleys, flying bars, as well as the supporting and retaining structures must also be dismantled. The electrical infrastructure, including cables, cable support systems and electrical cabinets of these overstage and understage systems, must also be dismantled. Steel work In the stage tower, there is a gallery on the left and right, which are connected to the fly grid via a spiral staircase. These must be completely dismantled. To do this, the pulley beams, winch support beams, grid floor, and flooring beams of the lower fly grid level must be dismantled. Wooden stage floor The wooden stage floor with a total area of approx. 190 m2 including the flooring sleepers must be dismantled. Overstage machinery The followings overstage machinery systems must be installed: 26x Powered fly bar winches Above the orchestra pit there is a powered winch drive of the forestage fly bar, with a lighting grid made of steel tubes on its 8 wire ropes. The winch drive works and is currently in use. The existing winch needs to be refurbished. This winch is installed in a very narrow and difficult to access cavity. As part of the renovation, better access for maintenance work on the winch will be created from above. Nevertheless, installing a new winch would be a lot of work. The existing winch drive is therefore to be refurbished and integrated into the new stage machinery control system. For this, in addition to the axis computer and frequency converter, the encoder, load measurement and limit switch also need to be replaced. The wire ropes and diverter pulleys also need to be replaced. The steel grid will be replaced by two flying bars. Understage machinery A new double-deck revolving stage is to be installed. The centre of this revolving stage is to be installed exactly where the current turntable is. The diameter of the upper deck is 10.6 m, like the existing turntable. The diameter of the upper deck is approximately 9.6 m. The upper deck will be supported on rollers on the existing concrete ring, on which the current turntable is already supported, as well as on steel columns that connect the upper deck to the lower deck. No stage elevators are planned for the revolving stage. However, as many 1x1 m trap doors as possible, which can also be combined in segments to form larger openings, will be integrated into the upper deck. A slip ring is to be installed for power and network transmission of the AV and lighting systems to the lower deck of the revolving stage. Stage machinery control system The stage machinery control system is intended to control all stage machinery systems listed above. Electrical infrastructure The complete electrical infrastructure for the stage machinery system must be installed. In addition to all the cabling on cable support systems, this also includes the cabinets for the auxiliary computers and frequency converters as well as the power supply cabinets. A closed electrical room in the sub-stage is provided for the upper and lower machinery. The supply line to the power supply cabinets is provided by a third-party contractor. Drive system safety curtain The existing safety curtain is approximately 6.4 m high and 9 m wide. There are counterweights to the left and right of the door leaf. A new winch drive must be supplied for this existing safety curtain. Stage tower Two new galleries are to be installed on the left and right of the stage tower along the outer walls. Stairs will connect the galleries to each other and the upper gallery to the fly grid. The lower fly grid is to be completely replaced. In addition to the new beams for the pulleys of the fly bars, new flooring beams between the roof racks also need to be installed. Additional support beams for the winch drives and the support of the sound isolation walls described below also need to be installed. Stage The substructures of the stage floor must be adapted to the new revolving stage. Stage floor A new wooden stage floor with a total area of approx. 190 m2 must be installed on stage level on the upper deck of the revolving stage as well as the stage areas around the revolving stage and the rear stage. The stage floor shall be the flooring sleepers.
