Much of Brazil's massive infrastructure programme is having to be built on the very soft soils found along the country's coastline. Not least are venues and infrastructure required for the Rio 2016 Olympic and Paralympic Games in the city's Barra da Tijuca district, where soft soils can be over 20 m deep. One of these, the 13 ha Athletes' Park, is already successfully completed. This paper presents and discusses the results of various in situ and laboratory tests that were carried out to assess the soil properties at the site. It then describes how the ground was substantially improved with a recent technique developed in Brazil called deep radial consolidation.
