Title: Central Station Subway Roof Replacement
Appears on pages(s):
Abstract:This paper outlines the design and construction methodology adopted for removal and replacement of a subway roof slab that supports railway tracks at Central Station in Brisbane, Queensland. The concrete subway roof had deteriorated and pieces of slab had spalled from the soffit. The subway was originally constructed in the 1880s and has undergone several modifications and extensions since that time. Platforms over the roof slab have also been extended and modified over the years. Part of the subway roof slab was covered by sand which supported the extended platform slab. The removal of the subway roof slab under the platforms required the removal and replacement of platform slabs, infill sand and platform walls in the vicinity of tracks with minimal disruption to the train services. Construction vehicular access was only available via the subway, and via a maintenance crossing. Due to the limited work space available for the construction, it was not feasible to use large cranes on the platforms. An innovative method was developed for the removal and replacement of the entire slab roof in a confined area within weekend closures of the tracks. The paper demonstrates how the construction detail was planned and drove the design.
