In Situ Site Investigation has vast experience with rail projects and have completed work across the UK and Ireland.

Work has included completing investigations in railway stations, on the track, for bridges and embankment stability. We have a selection of rigs to suit these varying scenarios including 1.5 tonne and 3.5 tonne mini crawlers, which are ideal for on track work where there is access along the cess or between the running rails. These are also used on areas off track with difficult access such as beneath railway bridges and difficult to reach areas at the foot of embankments or even on embankment slopes.

Our expanding rail capability includes three purpose-built excavator mounted CPT rigs that have been designed to attach onto road rail excavators (RRV). Once attached to the RRV, these CPT rigs can be transported along the track and the arm of the RRV is used to place the CPT rig in the desired position. This can be at various locations either on the track, down embankments or up cuttings. Having the ability to utilise two or three rigs on a single possession could save the client the additional cost of further possessions.

We were recently announced winners of the AGS 2020 Video competition! The time-lapse video above shows us using CPTs on a railway using one of our excavator mounted CPT rigs. Tests were completed either side of a bridge abutment to provide information about the ground material in order to rebuild a bridge.

CPTs and UXO tests on the Railway in Bristol– We utilised two of our excavator mounted CPT rigs for testing on the Great Western Railway

CPTs and seismic tests on Network Rail’s High Marnham Test Track– A research project with the University of Southampton, Network Rail and Aspin Foundation Ltd

CPTs on the rail for MML (Midland Mainline) in Bedford – CPTs completed along the MML in North Bedford between the track bed and embankment

CPT tests on Tottenham Embankment– Investigation of the ground for a replacement railway bridge; CPTs completed on either side of the embankment.
