    Behavioral transition: A framework for the construction conflict - Tension relationship
    (1/08/2007) Yiu TW; Cheung SO
    Conflicts are inevitable in construction projects. One of the reasons is that all construction projects involve complex human interactions. Previous studies have shown that behavioral states can respond dynamically as the magnitude of a conflict increases. This has been empirically demonstrated using a catastrophe-theory-based, three-variable system involving the level of construction conflict, the level of tension, and the amount of behavioral flexibility (Yiu and Cheung, 2006). This paper reports on a study that builds on the above-mentioned study by Yiu and Cheung, and examines the application of moderated multiple regression (MMR) to the three-variable system. It was found that not all MMR models display a significant moderating effect. Two out of six MMR models were found to be significant in their effect. These models affirm that the nature of the relationship between the degree of uncertainty and adversarial attitudes (or mistrust level) varies, depending on the behavioral flexibility of the parties. Disordinal interactions were also found, suggesting that the interaction between behavioral flexibility and the conflict-tension relationship can change radically. Critical points for the degree of uncertainty were also able to be calculated. Beyond these points, even a flexible individual may find difficulty in minimizing or resolving construction conflicts. As such, it is suggested that such radical changes could be prevented by minimizing the degree of uncertainty in construction projects. © 2007 IEEE.

    Catastrophic transitions of construction contracting behavior
    (24/11/2008) Cheung SO; Yiu TW; Leung AYT; Chiu OK
    The 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.

    Contingent use of negotiators' tactics in construction dispute negotiation
    (1/06/2009) Cheung SO; Chow PT; Yiu TW
    In the course of negotiation, negotiators' tactics should be responsive to the situational factors. This is commonly described as the contingent use of negotiators' tactics. This study examines this concept in construction dispute negotiation and has three stages of work. Stage 1 develops taxonomies of the three construction dispute negotiation dimensions: dispute sources, negotiators' tactics, and negotiation outcomes by exploratory factor analysis. A structural equation modeling is also used to confirm the taxonomies. Stage 2 examines the contingent use of negotiators' tactics on outcomes respective to the dispute sources through the use of moderated multiple regression (MMR). Stage 3 discusses the findings. The dispute source, "Delay" is found to be a universal moderator in the MMR analysis of the tactic-outcome relationships. That means when the dispute source is delay, a wide range of negotiators' tactics can be used, respective to outcome intended. It is also found that the most versatile tactics are those that seek progress. This group of tactics is effective in almost every group of dispute source and, in general, positive results can be expected. However, aggressive and assertive tactics should be used restrictively, as they will only be useful against a compromising negotiation counterpart. © 2009 ASCE.

    Exploring the influence of contract governance on construction dispute negotiation
    (6/10/2008) Cheung SO; Wong WK; Yiu TW; Kwok TW
    The obligations and rights of the contracting parties are typically set out in the conditions of contract. The attempt to have a "water-proof" contract that caters to all eventualities has turned contracts into management manuals with detailed contractual procedures to deal with, inter alia, performance, changes, payment, approval, and dispute resolution. Contract disputes, therefore, have to be negotiated within the ambits of the contracts. This study revisits the assumption of free negotiation that underpins most conventional negotiation studies, i.e., negotiation is free with rational negotiators who can walk away from the negotiating table at will. Constraints imposed by a contract are collectively described as contract governance. With taxonomies developed through principal component factor analyses for contract governance (CG) and negotiating behaviors (NH), the influence of CG and NH is explored by a Pearson correlation analysis. In general, it was found that dominating and obliging behaviors are mostly influenced by CG while compromising behavior is the least influenced. It was further found that procedural requirements influence all types of negotiators under the Rahim organizational conflict inventory except integrators. This suggests that if negotiators are having concern for both themselves as well as their counterparts, amicable settlement is possible notwithstanding the complex procedural requirements. © 2008 ASCE.

    Logistic regression modeling of construction negotiation outcomes
    (15/08/2008) Yiu TW; Cheung SO; Chow PT
    Construction disputes are always negotiated before other resolution methods are considered. When it comes to negotiation, the tactics used by a negotiator is central in deriving desired outcomes. This paper reports a research that employs logistic regression (LR) to predict the probabilistic relationship between negotiator tactics and negotiation outcomes. To achieve this, three main stages of work were involved. Negotiator tactics and negotiation outcomes were first identified from literature. Then, four LR prediction models with negotiation outcomes as the dependent variable and negotiator tactics as the independent variables were constructed. Finally, these models were validated with an independent set of testing data. These models collectively suggested that: 1) increasing time pressure, taking threats, or subjecting the opponent to reality testing are inductive to "deterioration" negotiation outcomes; 2) providing various options and increasing flexibility would achieve "substantial improvement" in negotiation; 3) relationships between parties could be maintained by fair play; and 4) focusing on information exchange, giving middiscussion summaries, and offering counterproposal could clarify a party's position. Despite the skepticism over frank and open discussion of the issues and the existence of game plan, the findings of this research do support some well-established negotiation principles-focus on the issue and play down behavioral factors. © 2008 IEEE.

    The aggressive-cooperative drivers of construction contracting
    (1/10/2009) Cheung SO; Yiu TW; Chiu OK
    Construction 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.
