[[File:Test_pit.jpg|thumb|Infiltration testing should be carried out at relevant stages down through the profile of a test pit.]]
The number of test pits or soil borings varies depending on site conditions and the proposed development plan. General guidelines are as follows:
The number of test pits or soil borings varies depending on site conditions and the proposed development plan. General guidelines are as follows:
* Where multiple test are carried out, they should be planned equidistant and mapped accordingly.
