AS 3798 Level 1 Earthworks Supervision Explained

What is AS 3798 Level 1 Earthworks Supervision?

AS 3798 Level 1 Earthworks Supervision is the highest level of testing and inspection for controlled earthworks in Australia. It ensures that fill material and compaction meet strict engineering and construction standards.

The standard was published by Standards Australia and is widely used across residential, commercial, and civil construction projects.

Level 1 supervision involves inspection and testing of earthworks to verify compliance.

Why Level 1 Supervision is Required

Level 1 supervision ensures that:

• Fill material is suitable
  
  

• Compaction meets specification
  
  

• Earthworks comply with engineering requirements
  
  

• The site is ready for structural foundations
  
  

It provides confidence that the ground will support buildings without excessive settlement or failure.

Many engineers require Level 1 supervision when:

• Filling sites
  
  

• Building house pads
  
  

• Constructing commercial buildings
  
  

• Preparing structural foundations
  
  

What Does Level 1 Supervision Include?

Level 1 earthworks supervision typically includes:

• Inspection of fill material
  
  

• Monitoring placement of fill
  
  

• Compaction testing
  
  

• Moisture testing
  
  

• Density testing
  
  

• Site inspections
  
  

Testing is carried out during the earthworks process, not just after completion.
