Public procurement in Switzerland represents a significant part of the economy, with annual expenditure amounting to some 40 billion Swiss francs. This sector is regulated primarily by the Federal Law on Public Procurement (LMP), which ensures transparency and fairness in the awarding of contracts. In Switzerland, all public contracts exceeding 230,000 Swiss francs for goods and services and 8.7 million for construction work must be subject to a published tender procedure. For example, in 2019, the city of Lausanne launched a major 250 million Swiss franc project to modernize its water management infrastructure, a process that involved both international and local firms. This approach not only ensures the best value for public money, but also encourages healthy and open competition, opening up opportunities for companies of all sizes, including local SMEs. Furthermore, with the recent adoption of ecological and social criteria in tender evaluations, Switzerland is demonstrating its commitment to more sustainable and responsible development.
