Track Systems

The scope of the Lot 2 works includes the installation of all track infrastructure within the Central geographical area, including through open route, viaducts and cut-and-cover tunnels. The track infrastructure incorporates the design and construction of: - standard pre-cast slab track (a separate supply arrangement); - mainline Switches & Crossings (S&C) units and 18 Rail Expansion Devices (REDs) on a combination of the aforementioned track forms (a separate supply arrangement); - the above includes the construction of any Hydraulically Bonded Layer (HBL) or intermediate concrete layers, sleeper blocks or pre-cast elements, and the installation of long welded rails (to be supplied free-issue to the Contractor); - buffer stops - a combination of permanent and temporary units to support a phased entry into service; - track spacing infill to provide drainage continuity to drainage systems installed by others; - cable containment (troughing), to support the routing of HV and LV cables; and - provision of (and subsequent removal of) a railhead at Calvert to be used for construction purposes, which is then subsequently converted into an Infrastructure Maintenance Depot (IMD) for the ongoing maintenance of HS2 Ltd's rail-mounted plant fleet. The scope of the Lot 2 works includes the development of the detailed design for all track infrastructure within the Central geographical area, and full integration of this design with the works of other Railway Systems packages. This Lot also includes the undertaking of static integration testing of the track system, as well as providing on-site support and facilitation of the dynamic testing phase coordinated by the client. The Lot 2 works also include the undertaking of Principal Contractor duties under the Construction (Design and Management) Regulations 2015 for the line of route up to and including the permanent boundary, plus any railheads or temporary construction compounds required to support the delivery of the works. This Principal Contractor role requires the provision of support to the client to manage the integration and prioritisation of construction activities, as well as the function of administering the Construction Railway Rulebook and managing the movement of Engineering Trains for itself and others within the working area.

The scope of the Lot 3 works includes the installation of all track infrastructure within the North geographical area, including through open route, viaducts and cut-and-cover tunnels. The track infrastructure incorporates the design and construction of: - standard pre-cast slab track (a separate supply arrangement); - High-Speed ballasted track (design and construction), to link the High-Speed infrastructure with the conventional rail national network in the vicinity of Handsacre (north of Birmingham); - mainline Switches & Crossings (S&C) units and 18 Rail Expansion Devices (REDs) on a combination of the aforementioned track forms (a separate supply arrangement); - The above includes the construction of any Hydraulically Bonded Layer (HBL) or intermediate concrete layers, sleeper blocks or pre-cast elements, and the installation of long welded rails (to be supplied free-issue to the Contractor); - track spacing infill to provide drainage continuity to drainage systems installed by others; - 324km of cable containment (troughing), to support the routing of HV and LV cables; and - provision of (and subsequent removal of) a temporary railhead at Berkswell to be used for construction purposes.

HS2 Ltd has established a multi-supplier framework agreement (FA) alongside the delivery contracts for lots 1, 2 and 3. The scope of work covered by the FA will be: — the works covered by lots 1, 2 and 3 (or the residual elements of those works) in the event of the termination or other failure of those contracts due to contractor default — other parts of the scope of lots 1, 2 and 3 works in the event they are omitted from those contracts for any reasons; — other optional works scope relating to the HS2 Track Systems or wider HS2 Project. HS2 Ltd appointed the following suppliers to the FA: • the successful tenderers for lots 1, 2 and 3 and, in the event they are different entities, • the second highest scoring tenderer for lots 1, • the second highest scoring tenderer for lot 2, and • the second highest scoring tenderer for lot 3. Any call-off contracts under the FA will be awarded following a mini-competition procedure, the rules for which are set out in the full FA. Only those parties appointed to the FA will be eligible to participate in such mini-competitions. There is no guaranteed minimum or maximum value of work to be awarded under the FA and HS2 Ltd reserves the right not to launch any mini-competition or award any call-off contracts under the FA, including for the avoidance of doubt, any call-off contract for all or part of the Delivery contract. HS2 Ltd reserves the right to provide in the FA for its use by any delivery body or other of its contractors or successor body appointed in relation to the HS2 Project to call off the Delivery contract. HS2 Ltd therefore reserves the right for the Delivery contract to be entered into by that delivery body or other contractor or successor body. The Delivery contract: HS2 Ltd reserves the right to award one or more call-off contracts for the Delivery works. The scope of works included within the Delivery includes the following: design and construction of —standard pre-cast slab track (a separate supply arrangement); —standard cast in-situ slab track or optional pre-cast slab track; —mainline switches and crossings (S&C) units and rail expansion devices (REDs) on a combination of the aforementioned track forms (a separate supply arrangement). The above includes the construction of any hydraulically bonded layer (HBL) or intermediate concrete layers, sleeper blocks or pre-cast elements and the installation of long welded rails (to be supplied free-issue to the Contractor); —buffer stops — either permanent or temporary units to support a phased entry into service; —track spacing infill to provide drainage continuity to systems installed by others; —cable containment (troughing), to support the routing of HV and LV cables; — provision of (and subsequent removal of) a railhead at stone to be used for construction purposes, which is then subsequently converted into an Infrastructure maintenance base; — rail served (IMB-R) for the ongoing maintenance of the clients rail-mounted plant fleet. The extent of the Delivery contract scope lot 4 works includes the design and installation of all track infrastructure within the geographical area, incl. through open route.
