Offsite steel solutions using platform principles

1. Steel composite cores Recent experience in North America has shown twin skin steel composite cores are substantially quicker to construct than the concrete equivalent. Their thinner walls also increase the usable floor area and reduce the load on the foundations. Although initial costs are more expensive than for concrete, there are speed advantages. The construction of Rainier Square in Seattle, with a twin skin steel core, was completed in 10 months rather than the 18 months anticipated with a traditional concrete core and at reduced cost overall.
