Finite Element Analysis technology issues are addressed for applications of the deep underground, soil mechanics, transport infrastructure and buildings. These application areas originate from both the civil construction and the petroleum engineering sectors. The main business drivers in these sectors are identified and explained and the purpose of Finite Element analysis is brought in relation to the business drivers. The state of practice of Finite Element analysis in each of the 4 areas is described extensively and illuminated with examples. Finally the general technology needs and topic for research are discussed.
