Works for complete or part construction and civil engineering work

Tender description

This procurement relates to Tunnel and Lineside Mechanical and Electrical works for the HS2 Project and HS2 Ltd intends to award a contract for the design, manufacture, supply, installation, testing, commissioning and maintenance until handover of the Tunnel and Lineside Mechanical and Electrical (M&E) Systems works for Phase One and Phase 2a of the project. Further information about the scope of works is set out in the remainder of this contract notice and in the pre-qualification pack (PQP). Expressions of interest are welcomed as set out in this contract notice and the PQP. The Tunnel and Lineside Mechanical and Electrical (M&E) Systems Contractor will be responsible for design, supply, manufacture, installation, testing, commissioning and maintenance until handover of the Phase One and Phase 2a M&E systems in open route and tunnels, including tunnel shafts and cross-passages. The scope of this procurement comprises a number of separate and distinct systems, which are categories under the mechanical and electrical discipline listed below: 1) Tunnel ventilation system — the purpose of the tunnel ventilation system is to provide a tenable environment within the tunnels (approximately 50 km of tunnels). This will include the delivery of the tunnel ventilation system using predominantly large axial fans in shafts (within long tunnels) and jet fans in the shorter tunnels. 2) M&E Subsystems — The purpose of the M&E subsystems is to provide some of the rail systems with power supplies and monitoring. The M&E systems include active and passive fire safety provisions within tunnels, tunnel cross passage doors (approximately 300 No) and associated system in bored and cut and cover tunnels, tunnel lighting, low voltage (LV) distribution, longitudinal handrails in tunnels, tunnel supervisory control and data acquisition (SCADA) systems and remote monitoring of equipment in shafts and key equipment in the wayside, passive provision for heating, ventilation and air conditioning, points heating and junction lighting. The overall length of open route is approximately 175 km. Further details of the scope of this procurement are provided in the PQP and further detailed requirements and responsibilities will be set out in the invitation to tender (ITT). HS2 Ltd is in the process of procuring a contract for the design, supply and installation of cross-passage doors. The executed cross-passage door contract will appear in the ITT documents and there will be an obligation on the tunnel and lineside mechanical and electrical systems contractor to enter into agreement to novate the cross-passage door contract from HS2 Ltd once the tunnel and lineside mechanical and electrical systems contract is awarded. The contractor will be required to work with HS2 Ltd to procure future maintenance or technical support from original equipment manufacturers and specialist suppliers. The estimated total combined value is between GBP 415 000, 00.00 and GBP 498 000 000.00 for phase one and phase 2a. For phase one, between GBP 370 000 000.00 and GBP 438 000 000.00 and for phase 2a, between GBP 45 000 000.00 and GBP 60 000 000.00.
