Infrastructure Development Code


The Contractor shall:

  1. General
    1. Remove all temporary services, machinery and surplus materials that have been used for the work from the area and leave the site in a tidy condition.
    2. Reinstate all surfaces to at least to their original condition or as otherwise specified.  The finished reinstatement shall have a neat appearance. Permanent reinstatement materials shall be similar in type, quality, texture, skid resistance and strength to the surrounding materials.
    3. Ensure all drains, fences and other structures are put back in their original place to their original condition or better. In the case of damage, repairs shall be undertaken using similar materials.
    4. Ensure reinstatement of roads and pavements shall be in accordance with CS-25.0 Reinstatement.
  2. Pipework
    1. Ensure the surface level of the reinstated trench shall match the surrounding surface level.
  3. Planting and Grassing
    1. Ensure that all paths and surrounding areas are clean. All plant labels are removed. Weed matting shall not be used. Channels shall be cleaned and weeded. All damage shall be made good to the satisfaction of the Council.
    2. Ensure that plants are picked over to remove prunings, dead or damaged leaves and any other object or material, including retail attachments such as labels. The edges of the beds shall be left evenly shaped and sloped.
    3. Ensure that for high maintenance areas such as roses, annual or perennial beds, the Contractor shall ensure that footprints are removed by lightly raking over the bed with a fork or hoe and that all surrounding areas are swept clean. Grass restoration where resowing is involved shall be included as a requirement under the defects liability period.
  4. Kerb and Channel
    1. If not already achieved during the kerb base construction, the carriageway shall be excavated to a minimum depth of 225mm at the channel face. The excavation base shall be flat and level up to the edge of the saw cut seal. All excavated faces shall be vertical.
    2. The subgrade shall be compacted to an equivalent CBR of at least 10 using the Scala Penetrometer, unless specified otherwise by the Engineer. Scala penetration results shall be converted to CBR utilising Austroads 2008 Guide to Pavement Design Fig: 5.3
    3.  The specified basecourse metal shall be placed on the prepared subgrade in layers not exceeding 150mm and compacted to refusal. The depth of the basecourse is dependent on the depth of surfacing, either asphalt or chip seal, but in no circumstances will it be less than 175mm (i.e. 50mm of asphalt surfacing).
