Clearance or treatment of unsuitable material

In order to prepare a site for construction work it will usually be necessary to carry out a site investigation. This will entail a study of site conditions to determine their probable influence on the design, construction and subsequent performance of a building. The following items may be encountered and are discussed in Approved Document C:

• unsuitable material such as turf and roots • mature trees which might affect services, floor slabs, oversite concrete and

foundations • pre-existing foundations, services and other infrastructure, and buried tanks • fill or made up ground • contaminants • high water table, which might necessitate sub-soil drainage to avoid damage to

the building.
