ABANDONED - HS2 Supply of Fleet of On-Track Machines Procurement

The general infrastructure maintenance equipment will need to be put together into a train suited for a particular task or tasks planned during a shift. This could be by coupling relevant vehicles together, by changing modules on the vehicles or by changing attachments for a particular purpose. To improve the OTM utilisation and efficiency of the fleet it is intended to have the general infrastructure maintenance machines be modular.

The below is a non - exhaustive list of some of the expected tasks to be undertaken by HS2 Infrastructure Management (HS2 IM) using the OTMs supplied in this lot. HS2 IM will undertake these tasks assisted and enabled by the plant and machinery supplied by the Supplier:

• Inspection and replacement of Overhead Catenary System (OCS) wires;
• OCS Registration;
• Maintenance, repair and replacement of GSM-R Masts and Telecoms Aerials;
• Replacement of Operational Communications and Signalling cables in troughs;
• Railhead conditioning – automated removal of detritus and application of adhesion improver at speed;
• Replacement of Switches and Crossings (S&C);
• Bridge inspections and minor works;
• Clearing drains;
• Replacement of cross-passage doors and door components;
• Access to tunnel lighting and signage;
• Tunnel leak sealing;
• Cleaning platform edge doors;
• Checking and replacing soil nails on embankments and cuttings;
• Maintenance of location cabinets; and
• Snow clearance – ability to attach a simple snow plough to the front of the machine.

Further detailed requirements and responsibilities will be set out in the Invitation to Tender

(ITT). Please refer to the Scope Document for further details. Additional information: Applicants must register their Expression of Interest in this procurement by registering on the

HS2 eSourcing Portal (see details in I.3 above). Applicants will then be able to download the PQP which includes HS2 Ltd's Applicant's Guide and accompanying procurement documents for information about conditions for participation.

HS2 Ltd will be using a suite of asset condition monitoring to monitor the condition of infrastructure assets. This consists of un-manned, remote, dynamic, autonomous and visual methods of inspection, to enable the most efficient life cycle of the infrastructure. To supplement these inspection methods HS2 Ltd will be undertaking mobile infrastructure monitoring using the passenger rolling stock which will be fitted with limited capability. To enable more detailed analysis, one or more OTMs will be required with the capability to undertake infrastructure monitoring. High speed runs will need to be undertaken at full OTM running speed or as limited by the line speed. It is expected that lower speed runs will be required to capture detailed data or for specific measurement techniques.

• Track (rail, slab, fixings etc), including ultrasonic and eddy current inspection as well as image capture;
• OCS (contact wire, catenary, registration);
• S&C/Rail Expansion Devices (REDs);
• Earthworks (cuttings and embankments, slab support structure);
• Tunnel (structurally and equipment/cabling);
• Bridge/viaduct (structurally and equipment/cabling);
• Noise barriers (presence);
• Telecoms (GSM-R strength);
• Monitoring to assess the acoustic performance of the infrastructure (rail); and
• Vegetation

The Infrastructure Monitoring capability will therefore need the capability to collect, store and transmit infrastructure monitoring data to the HS2 systems, such systems to be determined. Please refer to the scope document for further detail.

HS2 Ltd requires OTMs that facilitate the undertaking of the tasks listed below, these are indicative only and not exhaustive at this stage. These are centred on small to medium tasks all within the 4 foot or in close proximity to it. Some maintenance shifts that are undertaken on HS2 will need to be undertaken with Any Line Open (ALO) to traffic. All OTMs will need to facilitate this by providing protection to all staff undertaking these tasks. All new and old infrastructure components, equipment and staff will be transported to and from the worksite utilising the OTM whilst reducing manual handling whilst working. This will remove the need for staff to travel by road unnecessarily and infrastructure components and tools to be delivered in a separate process.

• Control, Command and Signalling (CCS) Maintenance requiring access to the four

foot e.g., replacement of axle

counters and balises;

• Rail head spot repairs;
• Rail stressing;
• Visual inspection of the underside of rails;
• Rail replacement of sections of rail up to 18m in length, including cutting out old sections and welding in new ones;
• Replacement of smaller sections of rail including RED half sets, the swing nose

and mechanical actuation;

• Replacement of point motors and point detectors;
• Minor repairs to the track slab, its joints and absorption panels. This will include ad-hoc replacement of individual

track slab panels; and

• Work on individual rail fixings and mountings.

All these tasks require provision of safe access for staff to the four foot without leaving the confines of the machine and a means to reduce manual handling of infrastructure components and tools. See the Scope Document for further details. Additional information: Applicants must register their Expression of Interest in this procurement by registering on the
