Supply: Includes sourcing approved materials from a quarry, paying royalties, and transporting them to the site. The material must meet specific technical requirements like "Proctor Density" or "Plasticity Index."
Installation: Includes site preparation (clearing vegetation), spreading the material in layers (usually 150mm to 300mm thick), watering for moisture control, and mechanical compaction using rollers or vibro-compactors.
Quality Control: Often involves field testing to ensure the ground is stable enough to support structures or roads.
