PLANNING & ORGANISATION COMMITTEE MEETING AGENDA                                   3 MARCH 2015


22.   The excavation of the site and the construction of the proposed works must not have
      any adverse effects on the stability of adjoining buildings and/or structures and/or
      services and/or lands. In this respect, a Registered Professional Engineer Queensland
      must supervise the excavation of the site and the construction of the new works to
      determine whether any additional measures are required to protect the stability of
      adjoining buildings and/or structures and/or services and/or lands.
      Site Stability
23.   The design and construction of the development must be carried out generally in
      accordance with the Geotechnical Study prepared by Morrison Geotechnic Job:
      DE14/231 dated October 2014 and the “Structural Design Concept” Job No14517
      Issue B prepared by TOD Noosa dated 29 July 2014. The documents must be revised
      to include the following:
      a.    a contingency plan and alternative design should the piled footing system as
            designed not be achievable due to unsafe working conditions or unexpected
            ground conditions
      b.    the document must be submitted to Council at the time of Operational Works
            approval.
24.   Should the recommendations of the geotechnical report or contingency plan require
      any part of the works (including excavation, retaining structures, tie backs, etc.) to be
      temporarily or permanently constructed within any adjoining property, a letter of
      authority from the adjoining property owner(s) must be obtained prior to the issue of
      the building permit.
25.   A suitably qualified and accredited consultant must undertake a detailed check to
      establish that a stable working platform has been constructed in accordance with the
      design prior to the use of heavy equipment or plant likely to cause vibrations on the
      site. Certification of the works to this stage must be provided to Council.
26.   A suitably qualified and accredited consultant must undertake a detailed check to
      establish that the screw pile and CFA piles have been installed in accordance with the
      design and that the required pile capacities have been achieved. Certification of the
      pile systems must be provided to Council.
27.   At the completion of the development a suitably qualified and accredited consultant
      must provide certification to Council that states that:
      a.    the development has been undertaken in accordance with the design
      b.    the development will not have any long term effects on the stability of the subject
            site or any adjoining properties
      c.    the site has a minimum factor of safety against landslip of 1.5.
      Stormwater
28.   A detailed stormwater drainage design prepared and certified by an RPEQ must be
      provided for the development. The works must be undertaken in accordance with an
      Operational Works approval and must include in particular:
      a.    the development must not cause an increase in the volume and velocity of
            waters discharged into the existing gully at the north of the house site in a Q2
            (0.393AEP), Q5 (0.181AEP), Q10(0.095AEP), Q50 (0.020AEP)and Q100
            (0.010AEP) rainfall event
      b.    all stormwater collected and outlet from the development (including the external
            catchment and driveway areas) must be outlet below the level of 26m AHD
