    Brief

    This contract involves the planning and management of the clearance of a former underground military munitions depot in Mitholz, Switzerland. Originally built during World War II, part of the depot exploded in 1947, leading to a reassessment of the risks associated with the remaining munitions. Recent evaluations in 2018 and 2020 have indicated a higher risk than previously assessed. As a result, the Swiss Federal Council decided on December 4, 2020, to proceed with the clearance of the depot and has established a project organization to oversee the planning and execution of the necessary work. This procurement opportunity seeks a contractor for the planning of excavation and material management related to this clearance project.
