Hamilton Harbour Australia Case Study

STUDOR SYSTEM IMPROVES ENVIRONMENTAL CREDENTIALS
(Full Cost Comparison Study Available)

The Studor System the chosen drainage solution for one of the fastest selling residential high-rise developments in the state of Queensland.

Background

Part of Devine and Leighton Properties’ prestigious Hamilton Harbour project in Brisbane, the Harbour One building is a 22 storey apartment block that houses 258 separate dwellings. The building sits on the banks of the Brisbane River in a landscaped parkland setting, which it shares with the smaller Harbour Two residential building and the KSD mixed-use precinct, which offers office space, retail and leisure facilities.

Christopher Contracting, who had worked on a number of previous Devine projects, were selected as the design and construct plumbing contractor for both residential buildings. After discussing with Studor’s Queensland Area Manager the various merits of the Studor Single Pipe System, particularly its cost-effectiveness, Christopher Contracting considered this an ideal opportunity to put the system to the test. They elected to install the Studor System in the larger of the two buildings, whilst the drainage system of Harbour Two was to be based on a Reduced Velocity Aerator Stack System (RVASS), which was the option originally specified on both buildings.

Planning & Preparation

The plans for the 24 stack drainage system utilising Studor technology were drawn up by Brisbane hydraulics consultants, Dennis Cairns and Associates. In total, the entire drainage system utilised 514 Studor Air Admittance Valves (AAVs) and 166 Studor P.A.P.A.s (Positive Air Pressure Attenuators). These were to be installed horizontally in the ceiling space between the habitable areas, thereby preventing any reduction in the amount of usable floor space.

Studor provided ongoing support throughout this process, including design assistance and compliance, to ensure the functional requirements of the Studor System were being adhered to, as well as local authority regulations.

Cost Comparison

From these initial designs it was apparent that the Studor System would offer significantly reduced pipework, which could provide a corresponding level of savings when compared to more traditional drainage systems that Christopher Contracting were familiar with. On this basis, they opted to proceed with the installation of the Studor System in the Harbour One building.

Results

Construction was completed in May 2011 and the building’s first occupants took up residence in November of that year. However, since that time the project has been used as the subject of a detailed study into the costs of supplying and installing a variety of high-rise drainage systems. Findings from the study, which was commissioned by Studor Australia Pty Ltd and conducted by independent designers and estimators, indicate that the Studor System was certainly the most cost-effective solution for the Harbour One building, offering savings of more than 17% compared to a traditional Fully Vented System and more than 6% compared to the Reduced Velocity Aerator Stack System that was utilised in the Harbour Two building.
