96.01.01 General


Civil works is a general term for hard surface areas outside of the building on the site that includes

  • roads, parking areas, bus bays, paths and hard-standing areas and games courts.

Design the civil works on the site from a “Whole of Life” (WOL) perspective to provide:

  • Value for Money
  • Fit for purpose
  • Long term reliability
  • Durability and servicability
  • Minimal maintenance requirements
  • Low maintenance costs
  • Having minimal impact on the site and environment from contamination, erosion, sedimentation, dust and noise both on completion and during construction

Refer to DG / WHOLE OF LIFE

  • For other vehicular traffic areas design for 1.0 x 105 repetitions of a standard axle load, as defined by AUSTROADS.
  • Allow for movements in the foundations caused by moisture variations and mine subsidence.
  • Design rigid pavements so there is no vertical differential movement between panels at joints.
  • For truck turning areas pavements shall be rigid in construction and finished with a reinforced concrete surface.

Refer to DG / STORMWATER

  • Design for subsoil moisture movements/seepage.
  • Provide sub-soil drainage to cut side of road or ramp pavements and to the back face of retaining walls.
  • Provide subsoil drains at all low points to remove water trapped in the base/sub-base course of road and paving formation.
 
96.01.07 Stability
 
  • Keep structures adjacent to the new works in a stable condition
  • Provide safe access to existing structures for when new work is adjacent to occupied buildings
 
96.01.08 Edging
 
  • Provide continuous edging of concrete or kerbs to free perimeter of roads and parking areas to ensure the stability of roadworks.
  • Timber edging is acceptable for footpaths only.
  • Provide a minimum 1 metre clearance between road edging and buildings, retaining walls and other obstructions.

  • Other concrete pavements shall be a minimum 100mm thick and reinforced with not less than SL72 mesh at top. 
  • Provide a thicker pavement and heavier mesh as the design requires and to meet durability requirements for minimum cover to reinforcement.
96.02.06 For Flexible Construction
 
  • For flexible construction finish with a surface coat of asphaltic concrete.
96.02.07 Joints
 
  • Provide joints to concrete pavements to prevent shrinkage cracks and to allow for temperature movements.
