This chapter highlights the importance and need to promote the concept of constructability and its evolution. Construction industry is extremely important worldwide as it provides infrastructural facilities for people and it is a huge employment-generating sector. The construction industry creates huge infrastructural facilities for the masses to use and enjoy. It generates employment opportunities for the communities. On the other hand, it is the biggest source of creating pollution and exhausting the nonrenewable resources of energy. The sustainable construction shall focus on three main areas of life cycle processes of building: its construction, utilization, and demolition or rehabilitation. The traditional design and construction practices focus on cost performance and quality issues. Sustainable design and construction adds the issues of minimization of resource consumption, environmental degradation, and creation of healthy, built environment as well as ensuring human health and comfort. The Construction Industry Research and Information Association (CIRIA) is nonprofit organization and works for the improvement of industry.
