Client: Network Rail
Sector: Rail Infrastructure
Location: South-West England
Project overview
The Chicken Curve embankment is a critical part of the rail network in the south-west of England. Following a significant embankment failure that disrupted rail services, Network Rail required a rapid and thorough ground investigation to inform emergency stabilisation works and long-term remediation plans.
Our approach
GIP was commissioned to provide an urgent and detailed ground investigation, delivering the data necessary for an effective and timely response. Our key services included:
- Site investigation under challenging conditions – conducting borehole drilling, dynamic probing, and trial pits in difficult terrain to gather accurate geotechnical data.
- Monitoring and data collection – installing inclinometers and piezometers to monitor ground movement and groundwater levels in real time.
- Laboratory analysis – performing comprehensive tests on soil and rock samples to assess strength, permeability, and stability.
- Clear reporting and design support – providing network rail with detailed reports and recommendations to support stabilisation measures and inform long-term embankment improvements.
Project challenges and solutions
The urgent nature of the project required fast mobilisation and efficient data collection in adverse weather and difficult ground conditions. Our experienced team worked around the clock to complete the investigation safely and on schedule. By using advanced monitoring equipment, we provided real-time insights that enabled Network Rail to implement stabilisation measures quickly.
Results
Our rapid and precise ground investigation played a key role in restoring rail services and ensuring the long-term stability of the embankment. The data we provided allowed for informed decision-making, reducing the risk of future failures and disruptions to this vital part of the railway network.
