                      Pavement Design and Construction
               68.    The pavement designs shown on the engineering drawings are not approved. To attain
                      approval for the pavement design, the following details must be submitted to Council and
                      certified by an RPEQ with the proposed pavement design:
                      a.      The design CBR must be based on the four day soaked CBR value for the subgrade
                              material;
                      b.      The design subgrade CBR must be representative of each homogenous insitu section
                              of finished subgrade. With respect to each section:
                              i.       For four or less test results, the design CBR must be taken as the least estimated
                                       insitu CBR result;
                              ii.      For five or more test results, the design CBR must be taken as the 10th percentile
                                       of all estimated insitu CBR results.
                      c.      The samples must be taken generally in the position of the outer wheel path on both
                              sides of the proposed road. A sketch plan showing the location of all tests must be
                              submitted with the test results for pavement design approval; and
                      d.      Where imported material has been (or is proposed to be) used for subgrade
                              replacement, and the depth of the imported material is less than 300mm, the pavement
                              design CBR must be based on the testing results of the insitu material and not the
                              imported material.
               69.    At the time of subgrade inspection, the subgrade must exhibit no visible signs of deformation
                      under proof rolling by a fully loaded water truck. The pavement subgrade will not be passed
                      until this requirement has been achieved.
               70.    Pavement design for privately owned works must be undertaken in accordance with the
                      relevant standards. Structural integrity of the driveway and car park areas will remain the
                      responsibility of the property owner/developer and must be certified by an RPEQ.
                      Works within Road Reserve/Reinstatement
               71.    Safe pedestrian access on all streets in the vicinity of the development must be maintained
                      at all times. Should footpath/road closures be necessary to carry out construction works,
                      Council’s Engineering Officer must be notified prior to the proposed closure and all
                      requirements complied with.
               72.    All frontage works must match neatly with existing road and verge/footpath features.
                      Additional works beyond the frontage may be required to provide an acceptable transition to
                      existing road and verge/footpath profiles.
               73.    The verge is to be modified such that the maximum crossfall for the verge is 5%, except in
                      the location of a pathway where the maximum crossfall is to be 2.5%.
               74.    Electrical conduits or other services proposed to be installed within existing and proposed
                      road reserves under existing sealed carriageways, concrete pathways, concrete/sealed
                      driveways or significant vegetation must be installed by boring. Trenching is not permitted,
                      unless specifically approved by Council.
                      Pathways
               75.    All pathways must be constructed in accordance with the following requirements:
                      a.      All footpaths must comply with Council’s Standard Drawing SEQ R-065;
                      b.      All paths must have a slip resistant surface;
                      c.      Expansion and contraction joints must provide a flush finish. Installation of joints by
                              saw cutting is preferred to ensure a smooth ride for cyclists; and
                      d.      The required work includes any modifications to ensure the footpath finishes flush with
                              all existing service covers and the like, or alternatively these services are raised or
                              altered, so as not to create a pedestrian safety hazard.
