Environmental Support, Bo’ness Railway

Temporary Works Design

Vibration Monitoring

Badger Exclusion

THE CHALLENGE

In autumn of 2016, BP employed IKM to design a temporary excavation across the Bo’ness Railway in order to access a 30m stretch of the Kinneil-Dalmeny pipeline for inspection and maintenance. The design required the installation of both temporary and permanent sheet piles approx. 2.5m from the pipeline. IKM carried out ecological surveys in advance of the works and identified three badger setts in close proximity to the works.  IKM also carried out vibration monitoring.

THE SOLUTION

A licence application was prepared and submitted to Scottish Natural Heritage (SNH) to ensure there was no risk to wildlife during work.

Prior to piling works commencing, IKM prepared for the client a site-specific vibration model, which calculated and predicted ground vibration levels to be experienced approximately 2 to 12m from the pipeline margins. This enabled thresholds to be set for ground vibration levels during piling, in compliance with BS 5228-4 (1992) and BS 5228-2 (2009). During piling IKM were able to relay real-time vibration data to the client, ensuring the integrity of the pipeline with each phase of construction. Throughout the project, IKM held regular onsite and offsite discussions with BP personnel in order to adapt the monitoring methodology to changing site conditions.
