Omsorgsbygg Oslo KF has automatic doors, particularly at nursing homes, fire stations, large and new nurseries, as well as other individual buildings. So that these technical installations shall have the expected function time and in order to avoid operational stoppages, regular inspections of the installations ought to be made. The aim of the procurement is to establish a system for periodic follow-up of all such installations. Well-functioning installations will improve customer satisfaction and reduce costs for repairs and replacements.
