Purchase of jet fans for Tårnby Tunnel

The tender concerns the purchase of a new ventilation system (jet fans) in Tårnby Tunnel to replace of the existing ones. Tårnby Tunnel is a cut and cover type and approximately 700 meters in length. There are two tunnel tubes, each accommodating one-way traffic, with ramps provided for each side of the tunnel. Each tunnel tube is 13.7 meters in width, with two traffic lanes, each 3.75 meters wide, along with an emergency lane, measuring 2.5 meters in width, situated on the right side of the tunnel tube. However, A/S Øresund is planning to use the emergency lane as a traffic lane in the future. Therefore, the tunnel ventilation system will serve for three traffic lanes in each tunnel tube. In total, each tunnel tube is currently equipped with 22 jet fans, which are placed within jet fan niches along the tunnel. The headroom in the road tunnel is constrained by the jet fans, ranging between 4.78 meters to 5.1 meters. The maximum allowable vehicle height in the tunnel is 4.5 meters. The highway is not accessible to pedestrians and cyclists; however, a side verge is provided along with the cross passages for safe emergency egress. The tender contains the purchase and delivery of new jet fans (including spareparts), including installation, testing, commissioning and documentation of the new jet fans and dismantling and disposal of the old jet fans. Furthermore, the contract requires the Supplier to deliver services in regards to work environment coordination, including planning of the works to be done (cf. above), arrange road blockage/closure when working in the tunnel and training/education of the Client's employees/supplier in regards to maintenance of the jet fans. The Supplier will be required to deliver additional works, such as projectmanager and supervisory services. Additional works will only be performed upon request from the Client. For further information about the content of the contract and goods, works and services to be delivered please see appendix 2 and appendix 3 to the Contract.
