Road barriers

Tender description

The supply of a moveable barrier system including associated equipment/plant/machine/vehicle, to enable the moveable barriers to be called into operation when required from their storage position and onto the carriageway to create a contraflow of traffic travelling in opposite direction. The location is on the M20 London-bound carriageway between Junctions 9 and 7. The objective of the scheme is to have the ability to implement a contraflow at short notice on the M20 Londonbound carriageway between M20 J9 and J7 (approximately 24 km) when disruption occurs in order to keep the M20 Motorway operational to all traffic. The solution consists of: (a) a safe and EN1317 compliant barrier system including 22 500 Quickchange Moveable Barrier (QMB) units, 1 000 Variable Length Barrier (VLB) units and 2 Road Zipper Barrier Transfer Machines; (b) Implementing a contraflow with a moveable barrier system on the M20 Londonbound carriageway; (c) storage of the moveable barriers along the Londonbound carriageway; (d) an operational procedure which achieves full deployment in 6-8 hours to the TM design specification; (e) Provision of all training in the UK to Highways England and subsequent refresher training for the safe operation of the moveable barrier system and associated systems. The moveable barrier system is to be fully operational by 31 December 2020.
