Exeter Depot Enhancement Works
HOCHTIEF is enhancing the maintenance depot facilities next to Exeter St David’s Station to support the introduction of new rolling stock and growing passenger numbers. Our scope of works includes a new carriage wash, three-road maintenance shed and offices on a brownfield site next to the existing depot.
- 3 road maintenance depot
- Staff accommodation – 3 storey office and welfare facilities
- Link bridge from offices to Exeter St David’s Station
- Carriage wash
- Fluid farm and delivery facility
- M&E, communications systems, security systems
- PWay including switches, crossings, turntables
- Utilities diversions
- Culvert diversion
During the Early Contractor Involvement (ECI) phase we engaged collaboratively with both GWR and depot staff to gain full understanding of their needs. Our integrated team looked in detail for opportunities to improve the design and provide operational benefits.
Both Exeter St David’s station and the existing maintenance depot must remain fully operational throughout construction.
As providing stabling capacity at night and carriage wash facilities are crucial to maintaining depot operations, we have proposed an alternative construction sequence that removes elements of work not related to the carriage wash from the critical path. This significantly reduces the programme risk and ensures that the depot will have the new stabling capacity on time.
We have redesigned the Taddiford Culvert diversion so that the existing train wash can remain in use until the new wash is operational, and we will work during the day and hand back the track each night to ensure continued depot operations.
