    Benefits, constraints and enablers of modular offsite construction (MOSC) in New Zealand high-rise buildings
    (Emerald, 2023) Shahzad WM; Reddy SM; Kahandawa R; Rotimi JOB
    Purpose: The ascendancy of modular offsite construction (MOSC) over traditional construction methods is well known. Despite the known potential of this construction approach, its adoption is minimal in New Zealand construction industry. This article investigates the potential benefits of using MOSC for delivery of high-rise buildings in New Zealand, underlying factors responsible for its low uptake and the measures that can facilitate its improved uptake. Design/methodology/approach: This study utilised a mixed research approach. An empirical questionnaire survey was carried out with New Zealand construction industry professionals with expertise in MOSC. Factor analysis of survey data was carried out using SPSS software. Semi-structured interviews were carried out with subject matter experts to get further insights and expand the survey findings. Interview data were analysed using thematic analysis. Findings: Study identified benefits of MOSC, thus establishing potential of its uptake for high-rise building construction. Constraining factors were investigated, most pronounced being low level of skills in construction industry to design, manufacture and integrate supply chain of MOSC, high initial investment, high cost of importing modules and negative perception about offsite manufactured buildings. This study also highlighted the enablers to improve uptake of MOSC. These enablers included; loan and mortgage policies to suit MOSC paradigm, building regulations to support OSC industry, increased support from the government and awareness and acceptance of standardised building designs among the clients. Originality/value: Originality of this paper harps from little to no research carried out to investigate use of MOSC for high-rise buildings in New Zealand context.

    Real options analysis of revenue risk sharing in post-disaster housing reconstruction
    (Emerald, 2021) Vahdatmanesh M; Firouzi A; Rotimi JOB
    Purpose: Post-disaster housing reconstruction (PDHR) demands a considerable percentage of global property investment, yet the post-disaster environment presents intricate challenges to reconstruction financing for governments and at the same time, revenue uncertainty for private investors. The purpose of this study is to develop a methodology for tackling land shortage and the financial challenges of PDHR in the aftermath of a disaster. Design/methodology/approach: This study developed a methodology based on a combined minimum revenue guarantee and maximum revenue cap model using a well-established real options analysis (ROA) for revenue risk sharing in PDHR projects and land readjustment (LR) for finance. The applicability of the purported model is demonstrated through an illustrative example. Findings: The results show that flexibility in the options could increase the PDHR contractor’s risk profile by increasing the expected value of the contractor investment and reducing the probability of investment loss. On the other side, a cap on the contractor revenue stream would allow the government to benefit from any excess in revenue and would counterbalance the value of the option. Practical implications: The framework proposed in this study could serve as a practical risk-revenue sharing in PDHR projects. Governments and policymakers could use the findings to enable the successful delivery of PDHR projects and consequently bring the quality of life of affected people to pre-disaster conditions. Originality/value: This study can be considered as a first attempt toward the use of the Australian barrier style options structure, and the trinomial lattice valuation model in PDHR projects, which incorporates LR, public-private partnerships, governmental guarantees and PDHR concepts in one ROA-based framework.

    How do personality traits affect construction dispute negotiation? Study of Big Five Personality Model
    (1/03/2011) Yiu TW; Lee HK
    This paper provides some leads as to how personality traits affect negotiating behaviors and negotiation outcomes in a construction dispute negotiation. To achieve this, a questionnaire survey was conducted. The Big Five Personality Model was used to measure the personality traits of construction negotiators. Factors of negotiating behaviors and negotiation outcomes were developed. By interrelating these three elements, moderated multiple regression (MMR) was used to examine how personality traits affect the relationships between negotiating behaviors and negotiation outcomes. The results suggest that 16 MMR models are of significant moderating effects on these relationships. Among them, the top five MMR models with relatively strong moderating effects are identified. These models reveal that the personality traits of extraversion, openness, and conscientiousness can significantly moderate the relationships of negotiating behaviors and negotiation outcomes. In addition, their moderating effects are plotted to examine their natures. Effective zones of extraversion, openness, and conscientiousness are identified to show precisely how these personality traits can effectively facilitate positive negotiation outcomes. These results provide construction organizations with indicators to which type of personality traits can help improve negotiation outcomes and optimize the overall performance of construction dispute negotiations. © 2011 American Society of Civil Engineers.

    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.

    Moderating effect of equity sensitivity on behavior-outcome relationships in construction dispute negotiation
    (1/05/2011) Yiu TW; Law YM
    This study builds on Adam's equity theory by examining the moderating effects of equity sensitivity (i.e., a person's perception of what is equitable or inequitable) on behavior-outcome relationships among negotiators in construction dispute negotiation. First, an equity sensitivity construct is developed. This construct reveals that most construction negotiators are entitleds, also known as takers, at the negotiation table. Moderated multiple regression (MMR) is used to test the moderating effects of equity sensitivity. The MMR models affirm that the nature of behavior-outcome relationships varies, depending on the perception of equity. An entitled construction negotiator is found to be a versatile moderator who fosters satisfactory negotiation outcomes. The models show that negotiators are able to predict inequitable responses and to take measures to forestall or deal with different inequitable situations. This study indicates the merit of further study of equity theory in the context of construction dispute negotiation. Future challenges in this area include the examination of the equity restoration responses of negotiators to create an equitable environment. © 2011 American Society of Civil Engineers.

    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.

    Impact of social media usage on performance of construction businesses (CBs) in Abuja-Nigeria
    (Emerald Publishing Limited, 27/07/2021) Oyewobi LO; Olorunyomi OS; Jimoh RA; Rotimi JOB
    Purpose Many construction businesses are currently building and keeping social media pages for their enterprises to be visible to the public to improve their social interaction, promote business interest, build trust and relationships with their targeted audience on social media. The purpose of this study is to examine the impact of social mediausage on performance of construction businesses (CBs) in Abuja, Nigeria. Design/methodology/approach This study used a quantitative research approach by identifying constructs that reveal three aspects of organisation’s physiognomies that impact the process of espousing, implementing and using technological innovations in conducting businesses. Well-structured questionnaire was used to obtain data from 113 purposively sampled building materials’ merchant operating in Dei-Dei Market, Abuja, Nigeria. This study used partial least squares structural equation modelling technique to establish the relationship among the constructs. Findings The results of this study indicated that technology has significant relationship with social media adoption, whereas social media adoption has a very strong positive impact on organisation’s performance (P < 0.001) with respect to improved customer relations and services and enhanced information accessibility. Research limitations/implications This study has implications for CBs that wish to adopt social media to promote their businesses by presenting to them the opportunity to understand the impact of technology, environment and organisational potential in improving business performance. This study is cross-sectional in nature, and this calls for caution in interpreting the results. Originality/value This paper developed and tested a conceptual framework presented to understand the interrelationships amongst the constructs, which would be of great significance to business owners in developing their social interaction and promote business interest via social media. The outcome of this research is beneficial to researchers to further study how the different social media tools could help in influencing business decisions.

    Migrant construction workers’ demography and job satisfaction: A New Zealand study
    (Emerald, 2021) Rotimi JOB; Ramanayaka C; Olatunji O; Rotimi FE
    Purpose: The demand for construction-related occupations has increased consistently over many years in New Zealand (NZ). This has necessitated recourse to migrant workers to address capacity and capability requirements. Migrant construction workers hail from various backgrounds with a complex set of their needs being met through employment in NZ. Research on understanding the satisfaction levels of this category of construction workers is scarce. With recent insinuations about migrant exploitations, research investigations into this knowledge area are significant. In this study, the authors sought to establish the moderating effect of migrants' demography on the determinants of job satisfaction in NZ's construction sector. Design/methodology/approach: Data were obtained from migrant construction workers of Chinese extraction through a structured questionnaire survey. From 200 questionnaires administered, 108 samples were completed by migrant construction workers involved in major projects in Auckland city, NZ. Data obtained were analysed using descriptive and inferential statistics to establish the moderating effects of their demography on job satisfaction. Findings: Results from this study support the internal validity and reliability of these personal characteristics as moderators of job satisfaction for migrant construction workers. These results suggest the relevance of personal characteristics of Chinese migrants in any improvement initiatives being developed for this group of construction workers. Research limitations/implications: The findings from this study contribute to the discourse on the relevance of construction migrants as a strategic alternative to addressing skill shortages within the NZ construction sector. They also provide evidence that contributes to an improved understanding of the migrant workforce to meet their aspirations and enhance their general well-being. Originality/value: Although the study is ethnic-specific, the conclusions show the relevance of personal characteristics in the experiences of construction migrant workers. The study is representative of the catchment of temporary migrant workers in the construction industry in NZ. The study provides insights for organisations employing migrants about putting in place appropriate measures to enhance their satisfaction levels. Finally, this study's findings may contribute to policy initiatives on the optimal categories of migrants engaged on construction activities to derive the maximum benefits for NZ.

    Barriers and strategies for building information modelling implementation: a comparative study between New Zealand and China
    (1/01/2023) Ma L; Lovreglio R; Yi W; Yiu TW; Shan M
    Building Information Modelling (BIM) is a sharing platform that can present a parametric 3 D model with various project information in the form of a digital display. In recent years, BIM adoption has become increasing globally as the Architectural, Engineering, Construction (AEC) industry has recognised its benefits. Meanwhile, many challenges of BIM adoption in different countries have been well documented. To address the gap in literature, this study examines the differences and similarities of BIM adoption between New Zealand and China. A questionnaire was conducted across the two countries to investigate the barriers and strategies for the implementation of BIM. Data from 146 respondents was collected in New Zealand and China. The result shows that there is a difference in the perception of Knowledge Barrier, Technology Barrier, Internal Strategy and External Strategy (Legal/Technology viewpoint) between New Zealand professionals and Chinese professionals. The differences identified offer important implications for government agencies to promote BIM implementation and for BIM service providers to better target the end-users.
