Hedges Dam Reconstruction
Survey support for Ertech on the full rebuild of the Hedges Dam wall near Boddington, covering machine control models, dam set-out, as-constructed surveys and volume and quantity calculations.
The Hedges Dam reconstruction near Boddington was a complete rebuild of all layers of the dam wall. Existing material was removed and the wall was reconstructed, with the works running from January 2021 to December 2022. Noble Surveys supported Ertech with machine control model creation and upload, dam set-out, as-constructed surveys and volume and quantity calculations.
The works were staged around the existing wall, and different materials had to be quantified after excavation and before placement. Our surveys gave the project team a measured record of each stage, using the same control and design data across machine control, set-out and as-constructed surveys.

Scope of work
Survey support from model to as-constructed
Noble Surveys prepared the machine control models the earthmoving fleet worked to, set out the reconstruction, and surveyed the works as material was removed and placed.
- •Machine control model creation from the design, with models uploaded to the earthmoving fleet.
- •Dam set-out for each stage of the rebuild, working from site control.
- •Surveys after excavation of existing material, before new material was placed.
- •As-constructed surveys of the rebuilt layers.
- •Volume and quantity calculations for the different materials removed and placed.
Project challenges
Rebuilding a dam wall in stages
Rebuilding every layer of an existing dam wall meant the works had to be staged, and the quantities for each material had to be captured at the right point: after excavation and before the next layer was placed.
- •A complete rebuild of all layers of the dam wall, removing existing material and reconstructing it.
- •Staging the works around the existing wall.
- •Quantifying different materials after excavation and before placement, so each could be measured separately.
Deliverables
- •Machine control models and uploads for the earthworks fleet.
- •Set-out for the dam reconstruction works.
- •As-constructed survey records.
- •Volume and quantity calculations by material.
