The Netherlands Authority for Consumers and Markets (ACM) carried out an investigation into statements about illegal cartel activities at Dutch construction firm Ballast Nedam. The investigation did not uncover any evidence of such activities. The statements in question had been given by a former project director employed with Ballast Nedam. However, Ballast Nedam will adjust its purchasing policies in order to reduce the likelihood of subcontractors engaging in illegal cartel activities.
In the fall of 2012, the preliminary investigation was triggered by statements in Dutch newspaper De Telegraaf given by the former project director. He has already been convicted. The preliminary investigation concerned projects in the period 2008-2011.
