ABSTRACT
The pile inspector allows to measure the geometrical enlargement of pile bases during the construction phase. Either connected to the kelly bar or attached to the service crane, the pile inspector is lowered into the drilled hole and measures the geometrical profile at the pile base, using 4 prestressed arms. Once the pile inspector is lifted out of the drilled hole, the installed reader transfers the gained data to the computer of the site engineer. The installed visualisation programme allows to visualise the results within a short period of time and displays the shape of the base of enlarged pile and the profile of the pile shaft.
