CHAPTER ONE
INTRODUCTION
1.1 BACKGROUND OF THE STUDY
The construction industry is an important part of the economical backbone in many countries (Ngai et al., 2002), often accounting for between 7-10 percent of the Gross Domestic Product (Winch, 1996, Voordijk et al., 2000). Furthermore, construction products and processes have a large impact on safety, health and environmental aspects (Bayliss et al., 2004). Since all human beings in modern societies are directly affected by its processes and/or products, the importance of a well-functioning construction industry is beyond doubt (Cheung et al., 2001, Ngai et al., 2002, Eriksson, 2007).
