Woolwich Dockyard Substation
The project objectives are to construct a new two storey sub-station building for Network Rail Power Upgrade. The site constrictions in terms of access and size were classed as a High Street environment and additionally the location was controlled by the requirements and regulations of Network Rail.
The building was designed by the client and consists of a steel framed unit with brick and cladding facades on a piled slab. A domestic width restricted cul-de-sac road provided the access, following the removal of a boundary wall. The buildings location is directly to the rear of a station platform and required the removal of a 15m x 5m high brick wall which was manually demolished from a scaffolding system.
We have installed 25 number 450 diameter CFA piles up to 12 metres deep from a reduced height mini piling rig, with all the progress adjacent to operational track. Close monitoring of logistics to overcome the restrictive site access was essential due to the site footprint and location. The steel frame was erected during engineering hours due to the proximity of the railway track. Seamless roofing, doors and ventilation grilles were installed after the brick and blockwork elevations were accomplished.
Utilising a 120 tonne crane the transformer unit was lowered through the roof area to its working location during a weekend engineering shift with appropriate closures. Roofing and flashing works were completed and external stairs, ladders and cable troughs installed in preparation of the building being commissioned.
External works to drainage, boundary walls and hard landscaping brought the project to completion.
