Groundworks businesses prepare land and install the below-ground structures needed before building or landscaping work can proceed. Services commonly include site clearance, setting out, excavation and earthmoving, levelling and soil removal, as well as digging and pouring foundations, footings and concrete bases. They may also carry out piling or other ground stabilisation work where site conditions or building designs require it. Other typical work includes installing drainage systems, manholes, soakaways and underground service ducts, and connecting or preparing routes for water, electricity and other utilities. Groundworkers may construct retaining walls, kerbs, access roads, paths, driveways and hardstanding, and undertake landscaping or reinstatement after construction. The work is usually planned around site surveys, building drawings and ground conditions, and can form part of a larger construction project or be commissioned separately.
