II.2)Quantity or scope of the contract

II.2.1)Total quantity or scope:

Network Rail (NR) wishes to source an earthworks remote monitoring solution. The purpose of the solution is to help NR identify earth movements (particularly on cuttings and embankments) which may lead to movement or obstruction of the track, posing a threat to train movements.
NR’s requirements are as follows:
1. The solution shall allow the remote monitoring of earth movements on the rail network.
2. Typical monitoring sites will be 100 metres in length with two rows of monitoring nodes spaced 5 m apart (approximately 40 nodes).
3. There is a current requirement to monitor 250 sites that will be located throughout the UK in Scotland, London North Eastern, Wessex and Western Routes.
4. Due to the remote nature of a number of the sites, power cannot be assumed to be available at the sites. Therefore, the solution shall be designed to work without a mains power supply.
5. The sensors, data logger and other on-site equipment shall be designed in such a way as to require the minimum of physical on-site maintenance and configuration and as part of this requirement NR envisage that the equipment battery life shall be at least five years under normal monitoring conditions.
6. The solution will be required to function 24 hours per day, 7 days per week sampling continuously and transmitting information when a set trigger level has been reached to effectively monitor earthwork movements. Full functionality is expected throughout periods of adverse weather as the risk of earth movement is greatest during or in the aftermath of heavy rainfall.
7. It is expected that the chosen solution will make use of tilt sensors mounted on the top of 2.5 m long metal poles driven into the ground to an embedment of 1.5 m to provide readings of earth movements.
8. The metal poles shall be segmented with screw thread connectors to allow different pole lengths in combinations of 1 m and 0.5 m to be utilised to suit different ground conditions.
9. The sensors should be fixed to the top of each pole by a threaded connector, tightened by spanner and if required with a means of ensuring they are aligned correctly.
10. The sensors shall be orientated on top of the pole so that the major tilt meter axis points directly down-slope, so that each tilt meter always records movement relative to the slope direction.
11. Exact locations can be locally modified within 1.5m in any direction to avoid trees and obstructions however this should be kept to a minimum.
12. The sensors shall be capable of operating in a range from – 40°C to + 60°C and evidence of this will be sought during the tender stage.
13. The sensing equipment (and hence the system) shall have the capability to detect any movement of the sensor in the x, y and z directions of more than 1 mm.
14. The sensors shall communicate wirelessly with a data logging device/gateway node and other nodes placed on the same earthwork asset (to prevent issues with trailing wires across the site).
15. The data logging device/gateway node shall connect to a GPRS modem powered by solar panels.
16. The sensing equipment shall have the capability to send movement readings and battery power levels to the central system (see below) based on the following triggers:
1. On movement beyond a set threshold (to immediately notify the central system of pre-defined significant earth movement).
2. Periodically (time based) e.g. every 3 hours
3. On request from the central system
17. The sensors shall be capable of receiving commands from the central system and hence the ability to receive remote configuration changes to include but not be limited to increasing the transmission rate of results.
18. The sensors shall be enclosed in casing with a rating of no less than IP68.
19. In addition to the tilt sensors, the solution shall also allow the central system to remotely view through digital still camera(s) “live” images of the 100m long site (to ensure that no earth or other debris has slipped down to track level).
20. The cameras shall be capable of dealing with daylight and night conditions, low and changeable light levels, and periods of adverse weather including heavy rain, hail or snow.
21. The cameras shall be installed on metal posts fixed permanently and securely in the ground. Cameras should be robust and reasonably vandal proof.
22. The cameras shall take reference pictures for comparison purposes and pictures upon request, when prompted by the central system, in response to movement events.
Solar Panels
23. Solar panels may be supplied to power the data logging device/gateway node, GPRS modem and cameras as necessary to deliver the five year battery life of the system.
Central Asset Monitoring and Control System
24. Network Rail require each of the new asset monitoring sites to be linked eventually to Network Rail’s own asset monitoring system (currently monitoring over 30,000 assets on the rail network) (PHASE 2). However, initially the Supplier will need to control the sites and host the data from the sites on their own IT monitoring and control system (PHASE 1).
25. The Supplier’s Phase 1 system shall not only control the sites and host the data from the sites but shall also provide a web accessible user interface to allow NR users to monitor the sites by viewing current and historic, sensor readings, battery levels and camera images. The alerts and alarms during Phase 1 will be required to be in email format to a dedicated Network Rail email address.
26. In both Phase 1 and 2 the sites will communicate with the central system using GPRS on the mobile network used by Network Rail. The sim card and monthly connection costs for each site will be provided to the Supplier at Network Rail’s cost. In circumstances where Network Rail’s usual mobile network does not provide the coverage required, Network Rail will work collaboratively with the Supplier to source the best solution at that site.
27. In Phase 2 the Supplier shall work with Network Rail to deliver the functionality of Phase 1 directly through Network Rail’s own asset monitoring system. An interface specification is available and shall be complied with.
Installation and Maintenance
28. Following suitable training of NR staff by the Supplier and joint site installation by the Supplier and NR staff at 10 sites, the equipment shall be capable of being installed and commissioned by NR staff with remote support from the Supplier to establish a fully operating connection between the system and the Supplier’s server.
29. The system shall be capable of operating during the five year life of the batteries with very minimal maintenance i.e. a maintenance visit required not more than annually.
30. The system shall be capable of working with some of the nodes out of action due to failure or damage and of accepting new replacement nodes with minimal re-commissioning.
31. In order to meet NR’s time-scales for installation of these systems onto the railway it is envisaged that Suppliers will need to have a system readily available (though possibly requiring limited adjustment to meet NR’s exact requirements) that can be demonstrated to provide the required outputs.
