Traffic response · MCU18/0019

The drawings included as Attachment 3 show the results of a vertical clearance assessment for a 12.5m
Heavy Rigid Vehicle as defined in AS2890.2, demonstrating that no underside scraping is expected to occur
on the driveway, or within the site, based upon the levels and gradients as shown in these sections.
Notwithstanding this, it is anticipated that the grading of the driveway and the crossover detail would be
refined at detailed design stage, prior to construction.
Issue –Driveway layout and basement gate
The parking layout plan does not include dimensions.
There is potential for conflict between vehicles entering the basement and service vehicles using the
delivery/loading area.
The basement access shows a gate which may restrict visitor access.
Information requested
10. Please provide:
10.1. a dimensioned parking layout plan demonstrating the details outlined in Section 3.3 of the QTraffic
report;
Response
The amended basement plan included in Attachment 1 includes dimensions of parking spaces and aisles,
which are designed in accordance the relevant Australian Standards, as summarised following:

    •    Standard parking spaces are 2.6m wide and 5.4m long, exceeding the minimum dimensional
         requirements for employee parking or car parking areas with low turnover rates as outlined in
         AS2890.1;
    •    The parking aisle is 6.2m wide (minimum), exceeding the minimum dimensional requirement for
         low turnover parking stipulated in AS2890.1 (i.e. 5.8m);
    •    The parking space for people with disabilities (PWD) is 2.4m wide with a 2.4m wide adjacent
         shared area, in accordance with requirements of AS2890.6. This parking space and shared area will
         necessarily have a fall not exceeding 1:33 in any direction, and a minimum height clearance of
         2.5m;
    •    Columns are positioned within the zone which is 750mm to 1,750mm from the open end of the
         parking space for manoeuvring to/from the space and pedestrian access to/from the vehicle, as
         required under the provisions of AS2890.1; and
    •    A terminated aisle extension of greater than 1m has been allowed for, to accommodate vehicle
         manoeuvring to/from the end parking spaces.
In summary, the carpark layout is efficient and legible, and designed generally in accordance with the
relevant Australian Standards.
10.2. a modified driveway layout that ensures that the swept path of the design vehicle (including
clearances) remains within the proposed driveway area (refer to QTraffic plan 755_KNG03 SK.02 A);
Response
The basement drawing included in Attachment 1 shows a modified driveway configuration, which would
be adequate to accommodate the entry and exit manoeuvres of a Heavy Rigid Vehicle (HRV) and a Refuse
Collection Vehicle (RCV), as shown in the drawings included as Attachment 4.
10.3. a plan with the clear delineation of the access to the basement carpark clear of the loading area, so
that all users are able to distinguish how that area will operate in an obvious manner; and
