Wellington Rail Station is a landmark building built on reclaimed land and has been recognised as one of the best 20th century buildings in New Zealand for its architectural qualities. The building is seen and used by thousands of commuters daily and is of heritage significance for its architectural, historical and technical values. The station connects over 8,600 commuters to more than 600 towns, cities and communities nationwide with over 390 services daily.

Following the 2013 Seddon earthquake, KiwiRail undertook a structural review of the station building. A number of areas were identified as requiring seismic strengthening including the original ticket hall roof, egress stairs, atrium, internal masonry walls and the clock. The works also included asbestos removal.

With all services remaining operational throughout the project the TSA team were responsible for successful management of a working site and attended site daily to ensure continuity of the project. Exceptional health and safety standards were adopted to ensure public safety at all times. Significant sections of steel were installed within ceiling spaces and corridors requiring strict protocols that ensured the building remained safe from fire and damage during the extensive welding process.
