Railway construction works

Tender description

It is envisaged that a number of engineering contractors will be appointed on a framework basis from which contractors will be selected on an early contractor involvement basis (ECI Contractors) to adopt outline system design for aspects of infrastructure improvements (e.g. Traction power supply, civil works, permanent way) and to develop detailed designs sufficient for construction, then undertake implementation works. Activities may include development of designs, specifications & associated prices, assisting in preparation of necessary statutory and Environmental Impact Assessment documentation, planning, programming and undertaking implementation on site. It could also include maintenance of the implemented system. Applicants who wish to express interest in this contract should wait for a further PIN or Contract Notice (CN) & do not need to respond to the CN inviting expressions of interest in undertaking the role of an Operator and Development Partner. Design, construct, implement & maintain a traction power supply system for the South Wales Metro transit system from outline designs, assisting with preparation of any necessary statutory and EIA documentation. The traction power system could include conventional Overhead Line Electrification (OLE), discontinuous catenary, ground based supply and single point rapid charging or other emerging technologies. Both AC and DC systems may be required. Responsibilities extend from main grid supply to sub-stations and local supplies including stations, depots, control centres etc. Possible overlap on other Lots but anticipated this Lot will include responsibility for piling, sub and superstructure required for OLE or other power supply systems. Design, construct and maintain civil works projects from outline designs, preparing statutory and EIA documentation. Scope likely to include new infrastructure and refurbishment of existing assets, interventions on tunnels, bridges, culverts, retaining structures, embankments, cuttings, rail stations, depots and access routes and ‘Metro’ related highway works. Majority of works lie within existing Network Rail ownership and/or access rights, but some may take place in third party land or on-street. Potential overlap on other Lots but anticipated this Lot to include responsibility for ground investigation and asset condition appraisal as well as preparation of rights of way for track widening or new spurs in advance of the track works & electrification. Design, construct and maintain modifications and developments to the rail permanent way, including preparation of necessary statutory and EIA documentation. While the majority of the works will lie within the existing Network Rail ownership it is expected that track dualling, signalling systems infrastructure, depots, new spurs and on-street alignments may be required.
