This research assessed the adequacy of a sample of 80 dwelling’s foundations in Wellington against the current “Light Timber Framed Construction Standard” NZS3604:1999 (including amendments 1 & 2). The study also attempted to quantify the expected reduction in fire losses due to remedial work on foundations, installation of flexible gas connections and seismic shut-off valves. It is currently understood that large earthquakes, most often overseas, have shown that many dwellings falling off their foundations due to inadequate bracing, also severed the reticulated gas connection between the ground and dwelling. Estimated reduction in losses was compared with the costs of carrying out the remedial work.
