Geotechnical engineering
Geotechnical engineering is the specialist branch of civil engineering concerned with the behaviour of earth materials and the application of soil and rock mechanics. Geotechnical engineers determine the physical, mechanical and chemical properties of soil and rock to design foundations, retaining structures and earthworks.
Earthworks specification
Construction frequently involves excavation and movement of material and this makes earthworks one of the most routine civil engineering operations. Although normally associated wi…
Read moreSettlement analysis
Soils consolidate under the application of loads from buildings. All foundations settle as the soil around and beneath the foundation adjust to the loading. Buildings with light lo…
Read moreSlope stability analysis
Slope stability is the potential of a naturally occurring or engineered soil slope (for example, embankments, cuttings, open-pit mining, excavations, landfills, etc.) to withstand …
Read moreFoundation engineering
Foundations form the base of a structure and are designed to transfer loads through the upper weak layer of soil to a stronger layer of soil or bedrock below. The primary concerns …
