Tender: Design and Supply of Dampers and Actuators for HS2 Tunnel and Lineside Ventilation

About

Costain is seeking a supplier for the design and supply of dampers and actuators for Package 15 of contract HRS02 delivering tunnel and lineside mechanical and electrical services for the HS2 high-speed railway. The package covers dampers and actuators within headhouses and ventilation shaft areas along a route of circa 180 km, including fan isolation dampers, tunnel isolation dampers, associated actuators and limit switches, and associated panels. Costain and HS2 seek innovative, smart solutions that deliver benefits in health and safety, installation and commissioning programme efficiency, cost, quality and assurance efficiency, whole life cost and carbon efficiency. Design development must rigorously meet technical requirements and include testing where necessary; the design and supply scope includes support to Costain’s design partner through concept and detailed design, ventilation analysis, modelling and calculations, product and arrangement testing, provision of samples and mock-ups, and commissioning support as required. Suppliers should assess their internal capabilities given the scale of the HS2 project before submitting an expression of interest.
