1.2 POTENTIAL RISK ELEMENTS – HYDRAULICS.

Further to our firm’s extensive review works of the hydraulic services, the main risk associated with
the development is the incorporation of the required infrastructure to cater for the rainwater
harvesting tanks and the fire services tanks, pumps and boosters.

    a) Fire Services Tanks.

        As previously noted, the Australian Standards and Brigade preference is for fire storage
        tanks to be located above ground, and for the tanks to be no more than fifteen [15] metres
        from the fire booster facilities to assist in efficiency in suction operations. The tanks can be
        no lower than three [3] metres from the booster level, and to achieve system efficiencies, the
        fire service pumps should be sited close to the fire tanks and booster.

        As noted in the previous text of this report, intervention by a Fire Engineer in the design
        phase of the development may result in a reduction in the volume of the fire tanks, but the
        above noted volumes of 288,000 and 86,400 litres respectively for hydrants/sprinklers are
        provided as “deemed to satisfy” solutions.

    b) Fire Hydrant Ring Main.

        It is highlighted that due to the expansive nature of the site, the site will require a fire hydrant
        ring main. Whilst the ring main can be easily designed, any dual pillar hydrant will need to
        be located within fifty [50] metres of hardstand to achieve compliance. This therefore
        denotes that a QFES Tender will need to access all areas of the site, to ensure the 50 metre
        ruling is compliant.

        Again, as noted in the above text, fire engineering solutions and strategies worked through
        with a Fire Engineer may enable alternate solutions to be considered, but the above
        references to the “deemed to satisfy” solutions.

    c) Supply of Potable Water for Consumption.

        The potable water supply is currently proposed to be sourced from treated rainwater
        harvesting processes.

        At the current time, legionella control is a major criteria in all aged care developments, and
        whilst compliance at the current time can be achieved through filtration and UV treatment,
        any potential changes to government legislation may necessitate further treatment to further
        refine water quality.
