Delays to delivery of the contract

2 Progress on Paddington Station began to diverge significantly from plan from March 2016, with the gap increasing until December 2017 when completed work was reported at 81% against the planned 94% (Figure 9 overleaf). The plan was re-baselined in January 2018 bringing the plan and actual completion rates in line for the first time. However, planned productivity rates could not be sustained and by March 2018 the actual work had once again fallen behind the plan. As at October 2018, reported progress was 94% complete against the plan of 97%.

3 Various factors caused schedule delays over the life of the contract. The complexity of interfaces with systemwide contractors (those who deliver works across the entire route) led to substantial amounts of design change, which contributed to delays to the design works. These design delays had knock-on effects on the subsequent delivery of mechanical and electrical works at the station.

Progress on Paddington Station has typically remained behind the planned schedule

Note

1 The dips in the planned progress line reflect the rebasing of the programme plan when Crossrail Ltd revised the Master Operational Handover Schedule.
