Shaping NSW since 1856

What is it we do at Public Works Advisory?

Public Works Advisory (PWA) supports local and state government agencies to deliver critical infrastructure initiatives by providing expert advisory, planning, delivery and support services. We bridge the gap between government and the private sector, helping clients to maximise value, optimise costs and manage risks in their infrastructure programs and the lifecycle management of their assets.

We have specialist teams with expertise in the lifecycle management of civil infrastructure, including water and wastewater, roads and bridges, river and stormwater and building projects.

These services are built on a solid foundation of more than 160 years of effective delivery and management of critical infrastructure projects for the State of NSW.

We continue to support the delivery of projects across regional and rural NSW. With more than 350 dedicated staff across our network of 16 regional offices, we are able to quickly and efficiently take on new projects or programs, tailoring the approach to achieve optimal outcomes for the client.

Sydney Harbour Bridge

Designed and constructed under the supervision of Public Works Department Chief Engineer John Bradfield, Sydney Harbour Bridge continues to stand in the spectacular harbour setting as an icon of Sydney and is the key transport link between the two shores.


Sydney Opera House

Following the resignation of original architect Utzon, a firm of Hall Todd and Littlemore was formed to complete the Sydney Opera House. Public Works managed the project’s three construction stages. It commenced in 1959 and opened in October 1973 and since then Public Works has provided consulting services to the Sydney Opera House Trust.


Water Supply Dams

Public Works has built over 100 major and minor water supply dams throughout NSW. Cataract, Avon, Cordeaux and Nepean Dams, built in the early 1900’s, are still a major part of Sydney’s water supply today. Dams such as Hume Weir, Burrinjuck, Oberon, Chichester and Adaminaby Dam continue to play a significant role in providing secure water supplies to Regional NSW.

Wastewater Treatment

Public Works’ contribution to the development of low cost sewage treatment technology for local communities ranks as one of the most sustained of any public authority in the world. The construction of reticulated water supply and sewage systems in Sydney and major country towns between 1880 and 1930 produced dramatic improvements in public health.
