CASE STUDY | Crossrail Liverpool Street Station by SymTerra
The central London station is one of the busiest in Europe – a new comms app for construction workers enabled contractors to deliver on time and budget the complex platform extension and renovations needed for the new Elizabeth Line.
As part of the platform extension and renovations scheme, works were planned to enable the new Crossrail trains to use platforms 16 & 17.
SymTerra was adopted to enable client MTR and its contractor BCM to obtain live updates from site on over 500 planned activities during a blockade at Easter. This allowed the project team to update the hour-by-hour programme in real-time, identify any change to the critical path activities and re-sequence works or re-allocate resources to ensure the station was reopened on time.
Works involved installing a new crossing, 205m of platform extension including platform widening, improved lighting 860 sq m of tiling, improved passenger safety and associated upgrades to signal renewals.
The project consisted of a 10-day railway blockade, with over 270 activities and nearly 200 people working three shifts a day.
With a tight turnaround and little margin for error, it was imperative the works stayed to schedule to avoid impacting the 26th busiest train station in Europe and around 200,000 commuters.
Features + impact
SymTerra gave the entire team, from the contractors to senior management, a real-time oversight of what was happening. This enabled them to make informed decisions and mitigate delays.
Throughout the blockade, on average there was an update every 12 minutes versus the norm of every four hours. This ensured additional resources were deployed to recover lost time and key people were prioritised on problem areas.
Over 270 activities successfully completed and documented in 1,200 photos, 700 updates and 50 reports making up a significant volume of project assurance data never seen before on a railway project.
Each update can be as short as a WhatsApp message or as long as a traditional site diary with photos and location information. This gives the team an unrivalled assurance pack with a full history of the works available for future projects to learn from.
The teams were able to update the hour-by-hour programme in real-time. The app allowed them to obtain comprehensive visibility over what was happening on site and confidently report back to stakeholders on progress.
Using SymTerra, MTR was able to provide cross-referenced project assurance and work records, exceeding Network Rail requirements.
All the works were completed within time, ensuring no delays to wider stakeholders and the station reopened on time.
The Liverpool Street project became one of the most documented blockades of its kind in the UK – over 1,200 updates and 3,000 photos for these works across three shifts a day over a 10-day period.
Matthew Stimson, MTREL project manager at MTR, said: “The use of SymTerra on the Liverpool Street Project allowed MTR to obtain comprehensive visibility over what was happening on site and enabled us to confidently report back to stakeholders on progress. The use of SymTerra also enabled us to review contemporaneous records of the delivered works which proved invaluable during our lessons learnt sessions and future work planning.”
