The project included 4nr rock cutting 5ch lengths (2nr renewals & 2nr refurbishment) and involved 3,200m2 of active rock netting and 580nr anchors to be completed in March 2022 utilising possessions and green zone working behind vortok fencing.

All works were completed by QTS’s in-house specialist IRATA teams and bespoke RRV plant. The tight timescales for the project meant we needed to use innovative design and delivery methods to ensure timely completion.
QTS and our design partner, Fairhurst, jointly developed a design solution to reinforce the PACE approach of overlapping design and implementation. Consisting of active Tecco mesh netting, we optimised the use of an RRV mounted drilling rig to secure the first 3 rows of bottom anchors and reducing HAV risks. Our key supply chain partners, Minova, ensured material availability. Innovative use of drone and lidar technology to carry out topographical surveys was adopted to improve safety by avoiding unnecessary track access and thereby reducing programme duration.
NR’s key objective was to mitigate this main line (SPC8) asset risk as quickly as possible. The entire scheme was completed within an 8-week programme from inception to handover reflecting QTS’s proactive and collaborative working approach with NR aligning to PACE, our rock cutting remedial works expertise and in-house competent roped access delivery teams. During this tight programme, we used 12 volunteer days to support the local community with their upcoming “Milford in Bloom” festival, celebrating flora and beauty of the local village. This scheme is being nominated by NR for a Railway Civil Engineers Association award.
