“…The fact that much of the waste produced in construction is common to many projects led to the study's hypothesis that there are imperfect institutional regulations, norms, and culturalcognitive framework assumptions within the construction procurement context, which support and/or encourage wasteful activities. Examples of these include: traditional lump-sum procurement systems based on price-competitive tendering (Winch, 2000b;Love et al, 2011b;Laryea and Hughes, 2008;Mohammed et al, 2011); silo thinking and resistance to change such that existing values and beliefs are not open for questioning (Winch, 2000a;Eriksson et al, 2008); traditional insurance products (Kent and Becerik Gerber, 2010;Ndekugri et al, 2013); textual complexity of standard contracts (Rameezdeen and Rajapakse, 2007;Rameezdeen and Rodrigo, 2013), disclaimer clauses (Zaghloul & Hartman, 2003;Love et al, 2010); late payments (Poverbs, 2000;,); the short-term focus as exemplified by clients' habit of changing suppliers between projects through the frequent use of open bid invitation procedures (Erikkson et al, 2008 unsatisfactory outcomes.
