Operational Works Application OPW21/0243 - Driveway application and supporting documents - 6 Robin Place, Lake MacDonald

STANDARD CONDITIONS
SITE PREPARATIONS
10.   Any excavation or filling must be undertaken in a way that suitably prevents soil movement, generally by the
      construction of retaining walls or suitable batter protection measures. Adequate support must be provided to
      adjoining properties and buildings at all times during excavations and construction work.
11.   Retaining walls or other types of soil retaining methods must be installed where the slope ratio for cut and or
      fill is greater than that specified in Table 3.1.1.1 the BCA. Embankments that are not retained must be
      stabilised by landscaping to prevent soil erosion.
12.   Drainage behind retaining walls must be provided in accordance with the approved engineering plans. The
      aggie drain behind the wall must discharge drainage water appropriately on site, and not be directed towards
      neighbouring properties.
13.   This approval does not include any retaining walls. If retaining walls over 1m in height are required, a
      separate or amended approval is required, and the retaining walls must be designed by a registered engineer.
14.   Drainage must be carried out in a way that protects land, buildings and structures in the neighbourhood of the
      building or land. Where retaining walls, fences, buildings or other barriers cause a damming effect or result in
      a concentrated flow of stormwater, an adequate drainage system must be installed.
15.   Excavation work for drains adjacent to buildings must be within the area shown in Fig 3.1.3.1 of the NCC.
16.   Roof and surface water is to be conveyed to the rainwater tanks, with overflow appropriately discharged on
      site in accordance with AS/NZ3500.3-2015.
17.   Surface water must be diverted away from Class 1 buildings. The external finished surface surrounding the
      slab must be drained to move surface water away from the building and graded at a minimum slope of 50mm
      over the first 1m from the building.
18.   The slab height is to be a minimum of 150mm above finished ground level - this height may be reduced to
      50mm for paved or concrete areas that slope away from the building.
      Note: The appropriate slab height above the finished ground level may also be affected by the height of the
      overflow relief gully, the possibility of flooding from storm runoff and termite risk management provisions.
19.   The minimum soil cover to be provided to Class 6 UPVC stormwater drains is 100mm. This may be reduced
      to 50mm under paved or concrete areas. In areas subject to light vehicular traffic the minimum required cover
      is 75mm under reinforced concrete or 100mm under paving.
20.   A termite management system must be installed to deter termites from gaining entry to the building via a
      concealed route. The termite management system must be selected appropriate to NCC OLD TABLE 3.1.4.1
      and comply with AS3660.1-2014, or have passed the test results required by Section 5 of AS3660.3-2014. A
      durable notice must be permanently fixed to the building in a prominent location, such as the meter box or
      kitchen cupboard.

FRAMING
21. Any steel framing must be constructed in accordance with NCC Part 3.4.2 and 3.4.4.
22. All timber framing must be constructed in accordance with NCC Part 3.4.3 and AS1684.2-2010.

ROOF & WALL CLADING
23. The roofing material must be appropriate to the required corrosion protection in accordance with NCC Table
    3.5.1.1 and the manufacturer’s recommendations. As the property is within 200m or breaking surf or 100m of
    calm marine waters, colorbond® steel ultra (or equivalent) is to be used.
24. Gutters and downpipes must be provided in accordance with NCC Part 3.5.3.
    Gutters must be installed with a minimum fall of 1:500, be suitable supported by brackets at 1.2m centres and
    have suitable overflow measures.
    Downpipes must serve no more than 12m of gutter length and be located as close as possible to valley gutters.
25. Valley gutters on roofs with a pitch of less than 12.5 degrees must be designed as a box gutter. Certification
    from the designer/installer must be provided confirming compliance.
26. External wall cladding must be installed in accordance with NCC Part 3.5.4 and the manufacturer’s details.

GLAZING
27.  All new glazing is to be supplied and installed in accordance with the requirements of BCA Part 3.6, and
     relevant parts of AS1288-2006 and/or AS2047-2014.

FIRE SAFETY
28.  Smoke alarms must be installed in accordance with Part 3A of the Building Regulation 2006 (the requirements
     of NCC Part 3.7.5 also apply but the Building Regulation provisions prevail to the extent of any inconsistency).
     They are to be installed as noted on the approved plans, so that they are located within each bedroom, and
     also between the bedrooms and other parts of the dwelling.
