The Emmental valley in the Swiss canton of Bern is world famous for its cheese and is also home to the family-run construction company O. Wyss AG set up by Othmar Wyss in 1960. Since its inception 50 years ago, this company has grown from a small construction company to a medium-sized company with an annual turnover of 10 million Swiss Francs in 2009. To achieve better quality in the civil engineering sector, the company, now run in the second generation by son Martin Wyss, began manufacturing pre-fabricated concrete manhole elements in 1990. Over the years, they have delivered steel moulds in the factory for making standard manhole bases with integrated seals and standardised channels of top quality. However, the company also wanted to pre-fabricate manhole bases with variable channel forms for several pipe connections, and carried out a detailed analysis to find a manufacturing process that could meet these requirements. O. Wyss AG found Schlüsselbauer Technology from Gaspoltshofen in Austria that offers a suitable procedure with their Perfect production plant for monolithic manhole bases. The first Perfect production in Switzerland was commissioned with a celebration at O. Wyss AG and just in time for the company’s jubilee in June 2010.
