Maatschappij tot Uitvoering van Zuiderzeewerken

The Maatschappij tot Uitvoering van Zuiderzeewerken (MUZ) (English: Society for the Execution of the Zuiderzee Works) was a consortium of dredging contractors in the Netherlands, formed in August 1926 for the specific purpose of executing the Zuiderzee Works. The Zuiderzee Works comprised a number of significant hydraulic engineering projects designed to dam the Zuiderzee, a large shallow inlet of the North Sea, to prevent flooding and reclaim land for agricultural and residential use.

The founding companies of the consortium included M.J. van Hattum's Havenwerken from Beverwijk, Hollandsche Aannemingsmaatschappij from The Hague, A. Bos from Dordrecht, and L. Volker.

MUZ was headquartered in Den Oever and was responsible for the construction of several key projects of the Zuiderzee Works, including the Afsluitdijk, a major dam and causeway completed in 1932 that converted the Zuiderzee into the freshwater IJsselmeer. The work carried out by the MUZ consortium significantly influenced water management and contracting practices in the Netherlands, but the lack of competition for major infrastructure projects arising from the creation of such a large entity attracted criticism.^[1][2]
