NATIONAL PROJECT OF THE YEAR 2018

Hornsby Track Slab Reconstruction Sydney Trains – Major Works Division (NSW)
NATIONAL PROJECT OF THE YEAR 2018
The Hornsby Track Slab Reconstruction Project was a high-profile construction project with political sensitivity as it was an enabling project for Transport’s ‘more trains, more services’ 2018 Timetable. The location of the work was shed 16 of Hornsby Maintenance Centre, which is used for maintaining, cleaning and stabling trains. The project scope was the complete renewal of a 340m x 20m concrete track slab with four roads of embedded rail as well as the trade waste drainage system beneath the track slab, required for train cleaning and graffiti removal operations. Planning and delivering a project of this scale would ordinarily take 2 years. This project however was completed in less than 12 months, for 23% less than budget, with no injuries or incidents. In this period, around 25,000 tonnes of spoil was removed and replaced with engineered backfill, nearly 600m of trade waste drainage was constructed, over 6,000 tonnes of concrete was laid and 1.2km of embedded rail was installed. This was an impressive achievement considering the challenges - the scale of the works, the compressed planning timeframe, working from incomplete designs, the severely constrained site access for work trains and construction plant, the resource constraints, and the requirement to plan all works around the continuing operations of the maintenance centre.
