            Additional details have been provided demonstrating the zone of stability for the
            telecommunications pole which will not be disturbed, and notes indicating no powered
            excavation near the services have been added to the plan to ensure they are protected
            during construction.

            18. Provide amended plans for the vehicle paths (B99 vehicle as described in
            AS/NZS2890.1:2004) that:
                   a. Indicate that vehicle paths (including overhangs) do not conflict with the
                   proposed basement walls (specifically spaces 1, 3, 5, 6 and 7);
                   b. Indicate separate plans for the entry and exit paths for vehicles accessing
                   spaces 5 and 7;
                   c. Indicate the width of car space 6 noting that the space is bounded on one
                   side by a wall and requires widening in accordance with AS/NZS2890.1:2004.


            The vehicle swept paths for the parking areas have been updated to ensure that the B99
            vehicle paths to not conflict with proposed basement walls nor the adjacent spaces in
            response to the above raised points. It is noted that a 300mm clearance envelope is
            shown around the vehicle body in accordance with AS/NZS2890.1:2004, which may
            overlap adjacent spaces, however this does not represent a conflict of the shown path.

            The spaces have been reconfigured to relocate the visitor space external to the parking
            garage to ensure visitors are able to park without requiring access to operate the vehicle
            turntable. Space 6 has been relocated as a result to ensure it has suitable widths in
            accordance with AS/NZS2890.1:2004. A separate entry and exit movement path has been
            provided for spaces 5 and 7.


            19. Provide additional detail on how visitors to the site will be able to operate the
            vehicle turntable if the particular resident they are visiting is not available.

            The internal parking area has been reconfigured with the visitor space relocated in front
            of the building to allow access and parking without requiring use of the turntable access.


            20. Provide comment from the design engineer regarding the potential for damage to
            the pits and if necessary and provide amended plans accordingly.

            The stormwater drainage line has been designed in accordance with the
            recommendations defined by the Queensland Urban Drainage Manual (QUDM),
            specifically in relation to the acceptable pipe grade limits and flow velocities.

            Section 7.11 of QUDM provides flow velocity limits to ensure scouring and erosion does
            not occur under full and partially full conditions where a desirable maximum velocity of
            4.0m/s under full flow conditions and 4.7m/s under partial flow are acceptable. The
            maximum flow velocity of the proposed stormwater line is 3.6m/s under the peak 1%
            storm event, therefore the flow velocities are below levels that would damage pit and
            pipe infrastructure.
