The project timeframe was extremely aggressive and in order to ensure the timescales were met, the Yellow Rail team were deployed on a 24 hours / 7 days a week rota 3 x shift pattern basis. The team of 34 experienced artisans included mechanical fitters, electricians, team leaders, senior team leaders, site manager and senior site management.

Yellow Rail identified, and competency assessed additional artisans, throughout the project, so that a constant pool of stand-by contingent labour was available to guarantee the required level of resource was available at all times. Yellow Rail supported the ongoing production planning to ensure we were aware of any issues / work fluctuations as soon as possible to ensure proactive management of potential issues.

Staff retention bonuses were introduced and all artisans were given detailed assignment notifications before deployment so that they were fully aware of the project scope and requirements. Yellow Rail allocated a dedicated project co-ordinator to act as the main communication point for all team members, to ensure they were able to discuss any concerns or request any assistance they may need at any time, to assist with team retention. 

Success and performance was measured by:

  • Programme 
  • Staff performance
  • Staff attendance
  • Staff retention

 

“Yellow Rail has delivered this complex and safety critical modification project very professionally and to the standards demanded by ALSTOM. The programme experienced several challenges as expected at the operational depot, but Yellow Rail demonstrated a high level of flexibility and focus, continuing to deliver units on a unit per day basis. We intend using Yellow Rail for other projects of this nature in the future.”
