The Background
The regeneration of Birmingham New Street station and the overhead shopping centre, was commissioned to facilitate the doubling number of passengers and to create a contemporary transport and retail hub.
BBI Services were engaged by Network Rail to provide improvement expertise across the project on multiple critical paths and levels.
The Challenge
4 years into the project in 2014, Network Rail recognised the need to reduce the atrium demolition programme by 50% from the original 12 month time scale to 6 months, to ensure on time completion in 2015.
At the same time, the station had to remain open for the 150,000 daily commuters. The work had to be completed in a logistically constrained inner city location, without breaking any upper noise limits.
The Solution
Throughout the ten months leading up to the demolition phase, we facilitated teams in the deployment of a number of tools and key lean techniques.
This ensured a standard visual approach to managing each of the critical paths, as well as the compression of the demolition programme.
These included:
- Setting up control rooms, BIM Visualisation and setting a pacemaker process.
o Ensuring the stakeholders could understand and contribute to the planning and management of the programmes.
- Conducting collaborative planning, waste analysis and problem solving activities, work studies and rapid improvement workshops, in order to make improvements across the board.
o Create a revised atrium demolition programme with stringent working constraints.
- Using set up improvement methodology to reduce a dispersal tunnel from 4 weeks to 48 hours.
o Allowed the critical path to proceed as planned, as well as minimising cost and passenger disruption.
- 4D modelling to detail the revised programmes, sequences and operating models.
o Simplification and standardisation of all the processes were key to reducing the time planned but also the level of risk to the programme.
The Results
Process improvements saved £28m across the project.
Self demolition achieved in 5 months – instead of the original 12 month plan.
Additional work incorporated on top of the original scope.
