Proper design, execution and subsequent validation reporting of earthworks are of vital importance in order to complete such projects, to satisfy conditions specified by local authorities and within the allocated timeframe and budget.

TSL has extensive experience in a large number of ongoing and completed earthworks projects, ranging from large quarry void remediation (see Quarry Remediation for more detailed examples) to small domestic projects. This has led to the formation of expertise when dealing with a wide range of scenarios which involve earth movement. Elements of this experience include:

• Restoration Quality Assurance (RQA) reporting

• Soil compaction trials to determine optimum water content and layer thickness of engineered fills

• Site supervision and in-situ/laboratory quality control monitoring

• Managing cut/fill budgets (minimises transport of materials and potential double-handling)

• Design of drainage systems

• Ground settlement analysis

• Verification testing

• Slope design and stability analysis
