- ItemCatastrophic transitions of construction contracting behavior(24/11/2008) Cheung SO; Yiu TW; Leung AYT; Chiu OKThe ways to manage a construction project very much depend on the attitude of the people involved. Collectively this is identified as construction contracting behavior (CCB). The CCB of the construction industry is adversarial as pinpointed in many industry-wide reviews. A more cooperative project delivery approach has therefore been advocated. In fact, drive for efficiency provides the incentive for cooperation. Nevertheless, members of a project team, in representing their respective organizations, are often in conflict. The dichotomous pair of cooperation and aggression forces therefore coexist. It is not uncommon to note that CCB turns aggressive as the construction activities of a project intensify. This change is often sudden and thus matches well with the phenomenon of hysteresis described by the catastrophe theory (CT). It is hypothesized that the dynamics of CCB can be modeled by CT. The three-variable CT models include CCB (as dependent variable), cooperation forces (as normal factor) and aggression forces (as splitting factor). With data collected from a survey fitted by the Cuspfit program, it was found that trust intensity is an effective normal factor. Contract incompleteness and competitive inertia are splitting factors that trigger aggression. © 2008 ASCE.
- ItemThe aggressive-cooperative drivers of construction contracting(1/10/2009) Cheung SO; Yiu TW; Chiu OKConstruction contracting parties can take either a cooperative or aggressive stance in pursuing their goals. This paper aims at identifying the stimuli (known as drivers) that motivate cooperative or aggressive moves in construction contracting behavior (CCB). In this regard, a three-stage research work has been designed for the completion of the research objective. Based on literature reviews, aggressive and cooperative drivers were identified in the first stage. A questionnaire was designed to collect construction case-specific data on these drivers. Next, taxonomies of aggressive and cooperative drivers were developed by the use of principal component factor analyses (PCFA). A total of three and seven taxonomies for aggressive and cooperative drivers were identified respectively. These taxonomies enable the understanding of aggressive-cooperative nature of CCB in a more amenable and logical manner. With these taxonomies, factor scales were calculated to represent the relative importance of the respective taxonomies. The degree of significance of each factor scales was then evaluated in the third stage. The results showed that the most important cooperative taxonomy is 'openness of contracting parties', while the most important aggressive taxonomy is 'goal oriented'. The findings also suggest that construction projects may not be inherently adversarial. Contract with equitable risk allocation and open discussion of problems would provide the platform for team building so that relationship among contracting parties can be maintained. © 2008 Elsevier Ltd and IPMA.
