Dynamics of control in construction project teams

Control is pervasive in construction project environments. The management of projects through various planning and control tools has therefore been described essentially as rebureaucratization which increases control over individuals, teams and organizations through ideologies of efficiency and performativity. Yet certain characteristics of the project setting make it an ideal climate for the empowerment of individuals and teams. The manifestations of control in five construction project management teams involved in two ongoing construction projects in Hong Kong are examined. The interpretive and exploratory focus of the study favoured the use of a qualitative research design and the case study approach in particular. Control is viewed as all devices and systems employed to ensure that acts, behaviours, outcomes and decisions of individuals, teams and organizations are consistent with meeting organizational or project goals, objectives and strategies. The findings indicate that a portfolio of control modes is implemented in project teams comprising both formal (i.e. behaviour‐ and outcome‐based) and informal (i.e. clan‐ and self‐based) control mechanisms which are not necessarily incompatible. While formal control remains the primary control mode, a portfolio of control appears necessary to augment the inadequacies of formal control due to the evolving nature of the project environment.

Empirical Investigation of Factors Contributing to the Psychological Safety Climate on Construction Sites

Employees’ safety climate perceptions dictate their safety behavior because individuals act based on their perceptions of reality. Extensive empirical research in applied psychology has confirmed this relationship. However, rare efforts have been made to investigate the factors contributing to a favorable safety climate in construction research. As an initial effort to address the knowledge gap, this paper examines factors contributing to a psychological safety climate, an operationalization of a safety climate at the individual level, and, hence, the basic element of a safety climate at higher levels. A multiperspective framework of contributors to a psychological safety climate is estimated by a structural equation modeling technique using individual questionnaire responses from a random sample of construction project personnel. The results inform management of three routes to psychological safety climate: a client’s proactive involvement in safety management, a workforce-friendly workplace created by the project team, and transformational supervisors’ communication about safety matters with the workforce. This paper contributes to the field of construction engineering and management by highlighting a broader contextual influence in a systematic formation of psychological safety climate perceptions.

Control modes and mechanisms in construction project teams: drivers and consequences

Control is purposive or goal directed, hence, there are underlying drivers and consequences of the exercise of control modes and mechanisms. In response to recent empirical findings that cast doubts on the empowerment–control incompatibility thesis, the broader question of whether control is predominantly ‘controlling’ or rather supportive in work environments is addressed. Drivers and consequences of control modes and mechanisms in five project teams involved in two ongoing construction projects in Hong Kong are explored. As an interpretive and exploratory study, a qualitative research design and the case study approach in particular was appropriate. Framework, category formation and cross‐case analysis techniques were employed to analyse data collected through documentary analysis, passive observations and semi‐structured face‐to‐face interviews. The exercise of control is driven by a range of factors emanating from the individual‐, team‐, organization‐ and project‐level. Control modes and mechanisms also have performance‐related consequences for individuals, teams and organizations and are predominantly attributable to self‐based control mechanisms. Preliminary evidence of the important link between self‐control/empowerment and performance is therefore provided which is instructive for the performance improvement agenda in the construction industry.

The Impact of Transformational Leadership on Safety Climate and Individual Safety Behavior on Construction Sites

Unsafe acts contribute dominantly to construction accidents, and increasing safety behavior is essential to reduce accidents. Previous research conceptualized safety behavior as an interaction between proximal individual differences (safety knowledge and safety motivation) and distal contextual factors (leadership and safety climate). However, relatively little empirical research has examined this conceptualization in the construction sector. Given the cultural background of the sample, this study makes a slight modification to the conceptualization and views transformational leadership as an antecedent of safety climate. Accordingly, this study establishes a multiple mediator model showing the mechanisms through which transformational leadership translates into safety behavior. The multiple mediator model is estimated by the structural equation modeling (SEM) technique, using individual questionnaire responses from a random sample of construction personnel based in Hong Kong. As hypothesized, transformational leadership has a significant impact on safety climate which is mediated by safety-specific leader–member exchange (LMX), and safety climate in turn impacts safety behavior through safety knowledge. The results suggest that future safety climate interventions should be more effective if supervisors exhibit transformational leadership, encourage construction personnel to voice safety concerns without fear of retaliation, and repeatedly remind them about safety on the job.

Social capital in construction projects : an exploration

The concept and phenomenon of social capital has been identified as an organizing logic that can add value to project organizations. In this respect, social capital is conceptualized as both personal and impersonal linkages between individuals in project organization, the quality of these linkages, and the shared representations embedded within these linkages. Social capital provides a means of coordination and collaboration among project participants. However, given the novelty of the concept in construction settings and peculiarities of construction projects, key questions arise as to what represents and are the forms of social capital in project settings? We adopt a mixed methods approach to answer these questions. Data from a survey of 376 respondents and a case project converge into forming a coherent conceptualization of social capital in construction projects. The findings confirm the multi-faceted nature of social capital and reveal the mechanisms by which social capital facilitates project organizing. Social capital appears to be more acutely needed in construction projects. While structural capital provides the platform for information and influence transfer, relational capital provides psychological safety upon which cognitive capital is translated into task performance. We conclude by discussing both the theoretical and practical contributions of the study to the relational governance discourse in project management.
