                                                                                                          ingeniir


       safe by providing a safe sight distance analysis on the intersection. The analysis must be
       prepared by a suitably qualified person (RPEQ – Registered Professional Engineer of
       Queensland).

       In response to Item 18, sight distances are shown on the Amended Engineering Plans in accordance
       with the IPWEAQ Publication Queensland Street, with consideration to operating speeds with
       adjacent corner radii.

Issue – Vehicle Manoeuvring
        The submitted plans do not include sufficient detail on the access driveway, the
        manoeuvring area and access into each proposed garage.

Information Required
      19. Provide additional detail on the access driveway and the manoeuvring area. The detail
      must be prepared by a suitably qualified person (RPEQ – Registered Professional Engineer
      of Queensland) and include, but not be limited to:
      a. a design generally in accordance with RS-049, RS-050 and any associated addendum;
      b. a longitudinal section extending from the centreline of the formation in Coral Tree
      Avenue to driveway adjacent to the garages; and
      c. demonstrate that a B99 vehicle will not bottom out of scrape while entering/exiting the
      driveway.

       20. Provide a Turning Path Plan that demonstrates how the driveway and manoeuvring area
       will function. The plan must be prepared by a suitably qualified person (RPEQ – Registered
       Professional Engineer of Queensland) and include, but not be limited to:Page 5 of 6
       a. demonstrate how a B99 vehicle, beginning and ending at the proposed ‘refuse area’, can
       enter and exit each garage while the proposed visitor carpark is occupied; and
       b. demonstrate how a B99 vehicle can enter and exit the visitor carpark while both garages
       are occupied.

       21. Provide comment from a suitably qualified person discussing what necessary safety
       controls are to be implemented to ensure the sight lines from the road frontage to the
       manoeuvring area remain unobstructed and to remove the potential creation of traffic
       hazards between vehicles entering and exiting the site simultaneously.

       Refer to the Amended Engineering Plans in response to Items 19 and 20 which demonstrate vehicle
       manoeurvring diagrams in the garage apron areas. It is noted that the apron width provided for the
       development exceed the requirements of AS2890.1 figure 5.4.

       In relation to Item 21, the access driveway is located along the northern boundary of the site. It is a
       straight driveway with no curves, structures or landscaping to hinder visibility. As a result sight lines
       are unobstructed to ensure no traffic hazards with respect to vehicles entering and exiting the site
       simultaneously.
