BMP was contracted in late spring 2013 by the German Embassy School in Beijing to design and engineer a new fresh air system, including state-of-the-art filter elements, in order to supply all classrooms, office and recreation rooms with pollutant-free fresh air. After an intensive design, tender and fabrication period before the summer break, airhandling-units, chillers, transformers and a multitude of ducts and cables were installed in a 24/7 schedule during the holidays. By end of August, 1 week before pupils and staff returned, all works were accomplished to the utmost satisfaction of the School Administration and the operations in the school resumed by much more favourable conditions.
