We implement our quality policy on the basis of ISO 9001:2015 procedures, for compatibility with GMP and constant improvement of the quality management sytem. We continuously strive to extend our theoretical knowledge, qualifications and practical competence and that is the reason we implemented BIm to our common practice. BIM is a concept which enables constant and immediate access to project data. It can be used to make project decisions, preparing consistent building documentation as well as estimates of profitability, investment costs, and the management of the site.
