| Summary: | In today’s way of installing a sheet pile in a non-cohesive soil, there is no well-known way to determine whether a sheet pile will be difficult driven or easily driven, based from the ground assessment made for each project (MUR). TESPA has concluded that driving speed of a sheet pile lower than 8 mm/second or 230,4m installed sheet piles per day defines drivability as difficult. A ground assessment consists of numerous geotechnical survey methods that has been made and summarized in one document. The information in the document varies after which type of probing method that has been used for the mission. Usually recurrent probing methods are dynamic probing and CPT. The purpose of this study is to identify if the ground assessment is sufficient to determine if a project will be difficult driven in a non-cohesive soil. Since the hypothesis is based on two projects, and it does not take the placement of the probes in to account compare to the actually location of the sheet piles, a specific value from the ground assessment cannot be established for the drivability. Despite this, after comparing the two projects, a high value of the dynamic probing can indicate when a mission will be difficult driven.
