Vibration effect on older buildings

Date: 2010-11-15

Vibration effect on older buildings is an enormously complex area. The conception of older buildings’ sensibility differs a lot between Sweden and other countries.  We are currently working intensely with the handling of the issue in connection with the construction of Citybanan and also in planning the new Slussen area.

Swedish newspaper DN recently wrote an article on Riddarholmskyrkan and Citybanan. Read the article here: http://www.dn.se/sthlm/sprangningar-skakar-city-1.1207852



Are you disturbed by your neighbours?

Date: 2010-11-02

Swedish magazine Hem & Hyra has in an article examined the not soundproof houses. In the article, buildings from different eras are classified in respect to soundproofing. According to the article, houses from the so called million projects are the worst. However, we do want to point out that these houses often fulfil, or almost fulfil, demands on construction of new houses (sound class C) regarding air and insulation of footsteps between flats.

Todays’ newly built houses are usually designed for sound class B, which to a much higher degree matches better sound conditions than sound class C.
