1.0 Introduction
1.1 Background to the study
The construction industry is dynamic in nature due to the increasing uncertainties in technology, budgets, and development processes (Chan, Scott and Ada, 2004). They further reported that, building projects are becoming much more complex and difficult, and facing unprecedented changes. Those uncertainties, along with many other documented problems, are the root causes of project delays and decline in construction projects performance (Ofori, 1991; Ogunlana, Promkuntong and Jearkirm, 1996).
The improvement of performance has become more critical to the success of construction projects which have been the subject of considerable amount of research and attention over the past two decades (Al-Otaibi, Omani and Price, 2013).
Studies have shown decline in construction projects performance both locally and internationally (Ogunlana, Li and Sukhera, 2003; Komolafe, Kingsley and Muhammad, 2014).
A number of authors have worked significantly on ways to improve performance from the view point of traditional criteria (i.e. cost, time and quality) (Neely et al., 1994; Idrus and Sodangi, 2010; Barkley and Saylor, 1994). Furthermore, in response to the decline of projects performance, several studies have developed and advocated the use of frameworks for assessing construction projects with a view to improve their performance (Cocca and Alberti, 2009; Kagioglou, Cooper and Ghassan, 2001; Belassi and Tukel, 2006). But the frameworks developed by several researches were mostly based on the traditional criteria that have been highly criticized (Paul, 2014).
