Infrastructure Development Code

CS-4.3 Excavation Management

PreviousNext

Cut areas shall be progressively excavated to form a uniformly graded surface within the batter limits. The Contractor shall form the excavations in a logical and orderly manner to minimise waste and shall undertake continuous visual inspections of materials as they are excavated. Any unexpected variations in material types or properties, evidence of slip debris, slope instability, observations of buried vegetation, groundwater flows, or seepages shall be reported to the Engineer immediately.

The earthworks shall be managed so appropriate materials are used for the various fill types as specified for use in the contract documents. The Contractor shall plan the earthworks carefully to optimise the use of the available fill materials. In particular the Contractor shall assess the volumes of different materials available, their locations relative to proposed fill areas and the degree of drying and conditioning required.

All earthwork surfaces shall be sealed off with rubber tyre plant when rain is imminent to minimise erosion and protect exposed materials from strength loss due to increase in moisture content.
