StatRapid restores confidence construction Thes Breda

As part of the development of the railway zone in Breda, Aannemersbedrijf Van Agtmaal BV is constructing a new building with basement for Client Thes. The six-storey complex will include studios, apartments and townhouses as well as commercial facilities.

TVSI piles were installed by Volker Staal en Funderingen for the foundation. The piles have been checked by Brem Funderingsexpertise BV with Integrity Testing. A number of piles showed a reflection directly under the pile head reinforcement, a well-known phenomenon with cast in-situ piles with pile head reinforcement. In general, it is believed that a possible crack will be closed under compressive load and that the piles are therefore suitable for transmitting compressive loads to the bearing layers. To verify this, it was decided to carry out load tests.

StatRapid is ideally suitable in this case, because several piles can be tested in a short period of time with limited preparation. StatRapid (a form of Rapid Load Testing) is described in ISO 22477-10:2016. In collaboration with Brem, Allnamics subjected 3 piles to a load test in accordance with class D of NPR7201:2017. The results showed that the shafts of the piles were indeed capable of transferring the load to the bearing layers. This result has restored confidence in the foundation and the work can be resumed.
