High St Stormwater upgrade

Randwick (Sydney)

Sydney Light Rail


1300m of DN375-DN1200 RC Stormwater in deep water charged ground. The scope also included construction of 75 Cast In-situ & precast drainage pits.
Time Period:
In April 2017 Vaughan Civil were awarded the complex stormwater package as part of the Sydney Light Rail construction on both sides of the road on High st – Randwick.


The Sydney Light Rail received a lot of scrutiny in the media over program and budget however one of the key benefits of the project was the offering alternative transport to high volume areas.

One of these areas in particular is High St, Randwick. High St is home to ‘The Sydney Children’s Hospital’, ‘The Royal Hospital for Women’, ‘The Prince of Wales Hospital’, ‘Sydney Surgical Centre’ and ‘The University of NSW’.

The 4 separate hospital entities and the universities all required regular stakeholder consultation to ensure the construction works had no impact on the sensitive hospital and research equipment, patient journey plans and congested traffic of staff, doctors, emergency vehicles, students, patients and the public.


While High St is less than 1km of the 14km if Sydney Light Rail the program works was a particularly dense due to the stormwater package being on the critical path for the construction of the High St Electrical Sub Station. Vaughan Civil completed the 6-month program in just 5-months having a positive impact of the High St master program.


The ground conditions were a challenge for the project was managing the deep excavations up to 3.7m in rock, sand and water charged ground.

High St is a high density residential and commercial area which has an unusually large number of services to allow the hospitals and university undertake day to day operations. Vaughan Civil had to install all 1300m of Stormwater without impacting a live service. This included the existing drainage which was managed with flow through plugs and by-pass pumps.
