Earthworks DesignEarthworks Design
When preparing an earthworks design for a
development there are a number of items which need
to be considered to ensure the economy, safety and
design life of the project.
Batter slopes
-Max generally 1v in 2h however subject to type ofmaterial and surcharge loads
-Slope stability (benching, surcharge loads anderosion)
-Long term factor of safety of 1.5

Sediment & Erosion ControlSediment & Erosion Control
To ensure that the proposed development does not
negatively affect the environment we are required to
ensure that sufficient measures are in place to control
sediment and erosion.

There are a number of approval processes which
may be required in order to commence the
construction of your engineering design.
Different processes depending on whether worksare internal or external to the lot boundary
