As in other industries, firms in the construction industry need to become more client- and market-oriented. In the last decade, several initiatives have been taken to change the construction industry in that direction. The changes, however, seem to be slower than other industries and less forthcoming than projected. Old practices and patterns die hard. Fundamental changes in orientation, strategy and strategy deployment require shifts in the management paradigms (i.e. the 'frames of mind' that steer individual and collective behaviour). Management is seen as a crucial factor in these change processes, but can the new business be created by old management paradigms? Can the leaders in the construction industry shake off the old paradigms? An explorative quantitative study shows that the mainstream paradigm of construction industry leaders today is much as it was in the past: technology- and project-oriented. Acting out of this paradigm, issues as social-organizational change and strategic focus on the client - regarded as important for the industry - will probably not be addressed properly. Change initiatives could gain in success, when they create wider awareness of existence and persistence of incumbent and prevailing paradigms.Construction industry, innovation, paradigms, barriers to change, construction management,

In recent years, the number of publications on innovation in the construction industry has increased. Many of these documents address qualitative issues, e.g. policies for innovation and present case studies. A more quantitative approach is taken in this paper, which is the continuation of a previous study. It focuses on main types and sources of innovation in the construction industry, and includes an analysis of 55 years of publications in two leading Dutch professional journals. The results show a recent increase in innovation, with two-thirds of innovations coming out of supplying industries. Construction companies contribute mainly in process innovations. Innovation in construction remains to be technology- rather than market-driven. Regulations have a surprising impact, as over one-third of all counted new innovations are related to new regulations.Construction industry, innovation, management,
