About Cut and Fill

Bulk earthworks use cut and fill to minimise the amount of construction labor, time and cost involved in earth moving. It is accomplished by balancing the amount of material from cuts to roughly match the amount of fill needed to level a site or create an embankment.

Estimating cut and fill from Surveys and Lidar

To estimate cut and fill volumes, relative level data is gathered by surveyors to generate a topographic map of the site. Lidar data can be utilised which provides an elevation point every square meter providing unparalleled detail. Lidar data is typically one to seven years old and may not show a site in its current state. Broadcrest utilises high resolution Lidar point data in collaboration with survey data to develop the most accurate site model available. In instances when the client has not engaged a surveyor Lidar data is used for preliminary cut and fill volumes, saving time and money during the feasibility and initial design phase.

Designing Cut and Fill

During the design phase an investigation into determine likely subsurface conditions, ease of excavation, excavation extents and batter slopes. The cut and fill investigation is used to develop a 3D model showing the layout, levels and planning dimensions. Earthwork quantities are pulled from the detailed cut and fill design to guide your estimators towards accurate costings.
