Hydro Construction Products had the privilege to provide a variety of heavy-duty polymer concrete drainage channels, trench drain grates, ductile iron and stainless steel grates for 1 William Street development project in Brisbane. Since 2003, Hydro Construction Products have continuously provided clients with high-performing water management products and solutions that integrate function and design required for the project.
With its close proximity to the Parliament House, the "Tower of Power" is home to the Queensland Government, public servants and the general public. The bulk of the building design is allocated for government spaces and offers a series of outdoor spaces for community activities and programs at street level. It holds a dynamic network of pedestrian corridors that connect the site to its surroundings.
Hydro Construction Products worked with Cbus Property and Multiplex in the culmination of the $650 million project. Following the completion of a government office on Charlotte Street, 1 William Street is the first commercial office building commissioned for the government in the Brisbane CBD. Hence, the design specifications were clearly focused on accessibility, functionality and aesthetics.
Below is the list of water management products used for the 1 William Street Project:
