Datum Fleming Award Finalists

December 8, 2017

The Datum Group were honoured at the prestigious 2017 Fleming Award for their monitoring work at the Garrion Gill Slope Remediation Scheme.

The £4.7 million Garrion Gill Slope Remediation Scheme was one of three finalists shortlisted for the award presented to recognise excellence in the practical application of geotechnics in a project.

Datum were part of the team led by COWI UK that included Network Rail Infrastructure Projects Scotland, QTS Group Ltd and Cementation Skanska tasked with solving an issue which was affected the West Coast Line for more than 60-years.

Garrion Gill is an ancient woodland reserves clinging to the slopes of the Garrion Burn, home to diverse plant habitats, badgers, roe deer and birds including spotted flycatchers, sparrow hawks and woodcocks.

Records suggest ground movement has existed back to the mid-20th Century and as a result, speed restrictions across a 65m section of of track near Wishaw in Lanarkshire, have been in place since the 1950s.

Ms MacInnes, said: “A routine track inspection in February 2013 showed there was vertical movement of the track.

“An 80km/h speed restriction had been in place since the 1950s because of movement, which was managed with ballast packing the past.

“Monitoring was critical. We had a huge monitoring system installed by Datum with tilt meters and rotation monitors in place, as well as an action plan for evacuation should the worst have happened.”

The 11-month project was featured in the December edition of Ground Engineering magazine. The article highlights the innovative use of drilling and grouting, micro-piles and rock full buttresses used in the project which established a new approach to slop stabilisation. It finally allowed Network Rail to lift the speed restriction.

Datum provided track monitoring services using TrackMates across the 300m of track to measure for potential track rotation.

TrackMates are innovative wireless track cant monitors. They attach to any sleeper type and continually stream data wirelessly, sending alarms if upper or lower limits of movement are breached.

Datum deployed the SlopeMate and SlopeMate Arrays to monitor for potential slope movement ahead and during remedial works.

The Garrion Gill Slope Remediation Scheme was shortlisted for the Fleming Award alongside the Pines Hotel Cliff Stabilisation Scheme and the PISA Project, who were ultimately crowned winners of the award.

The Fleming Award is organised by the British Geotechnical Association and is given annually to commemorate the life and work of former Cementation Skanska chief engineer Ken Fleming and to recognise excellence in the practical application of geotechnics, teamwork, expertise and innovation.
