Abstract

Purpose

Effective procurement of infrastructure is linked to the attainment of the sustainable development goals set by the United Nations. While the capacity of organisations is generally thought to be related to organisational performance, there is a lack of empirical insights concerning the contribution of procurement capacity of public organisations towards the attainment of procurement objectives in infrastructure procurement. Thus, it is unclear which aspects of the capacity of public procurement organisations contribute the most to the attainment of procurement objectives in the procurement of infrastructure. This research sought to address this gap.

Design/methodology/approach

The research used a survey of public procurement professionals which yielded 590 responses.

Findings

Exploratory factor analysis of 23 organisational capacity items revealed three components of organisational procurement capacity: “management of the procurement process”; “human and physical resources”; and “financial resources and management”. Multiple regression modelling of the relationship between the components and the attainment of 12 procurement objectives further reveals that there is a significant positive relationship between the three components and all the objectives. However, “management of the procurement process” emerged as the greatest contributor to the attainment of seven objectives, whereas “human and physical resources”, and “financial resources and management” were the greatest contributor to the attainment of one objective and four objectives, respectively.

Originality/value

The study provides strong empirical justification for investment in the development of procurement capacity of public agencies involved in procurement of infrastructure. Furthermore, procurement capacity development of specific capacity components can be prioritised based on the relative contribution of capacity components to the attainment of desired procurement objectives. This should be useful to government policymakers as well as multilateral organisations that fund infrastructure and procurement reforms in various countries.

Abstract

Purpose

In spite of emerging research on building information modelling (BIM) capability assessment, there is a general dearth of knowledge about the links between often pre-emptive capability measurement attributes and actual delivery success. More so, current studies have not considered success from the wider construction supply chain (CSC) perspective. So far, the perceived importance of capability metrics is not based on post-project evaluations of their contribution to BIM delivery success. This paper aims to identify relevant BIM capability attributes used for qualifying CSC organisations for projects and further aims to investigate their relative importance and influence on some key aspects of BIM delivery success.

Design/methodology/approach

Based on heretofore validated set of BIM capability attributes from semi-structured interviews and a Delphi study, a survey of CSC firms on BIM-enabled projects was used to model the influence of BIM capability attributes on BIM delivery success. Multiple regression modelling was performed to ascertain the nature of the relationship between BIM capability attributes and the key aspects of BIM delivery success as identified from the literature.

Findings

BIM staff experience and the suitability of proposed methodology prior to project commencement were identified as the most influential on BIM delivery quality, as well as delivery within schedule and on budget. Conversely, the administrative and strategic-level capacities were found as the most influential in leveraging collaboration, coordination or integration of the CSC on projects through BIM.

Originality/value

This study provides a step change in prioritising BIM capability criteria based on evidence of their contribution to delivery success in key performance areas, rather than their perceived importance as capability metrics as widely practised.

Abstract

Purpose

The purpose of this study was to determine the transaction cost (TC) contractors incur when tendering for a project as well as establish a correlation between the TC of tender and tender amount of projects procured through the national competitive bidding procurement method.

Design/methodology/approach

The research draws extensively documentary analysis, observation and interviews to collect cost data on 14 different tenders submitted by a D1/K1 contractor. Using TC theory, the data are analyzed and the actual cost is determined. Further, Spearman rank correlation is employed to establish a relationship between tender price (TP) and the cost of tender by the aid of Statistical Package for Social Sciences.

Findings

The research developed a tender preparation conceptual framework highlighting the components of TC in competitive tendering in Ghana and also revealed that, apart from the emotional and psychological costs, contractors in Ghana incur approximately Gh₵ 4,625 (US$ 925)–Gh₵ 2,520 (US$ 504) to prepare and submit a competitive tender. In relation to the tender figure, the TC of tender in Ghana ranges from 0.05% to 0.65% and an average of 0.33%. Also, there is an inverse correlation between TP and the percentage cost of tender.

Research limitations/implications

The research relied on 14 competitive tenders and also limited to public sector works. Findings from the study should therefore be applied with caution.

Originality/value

This study is the only known research that has focused on assessing the TC of public sector competitive tendering from a contractor's perspective and within a developing sub-Saharan African context.

Abstract

Purpose

The construction industry has been subject to substantial criticism for its short-term “hit-and-run” relationships which are focussed on win-lose situations. Despite the wide recognition of these problems the industry persistently resists the radical demanded of it. Therefore, the purpose of this paper is twofold. First, to investigate why this might be the case by reviewing the governance problem confronting clients and decision makers in construction procurement, as conceptualised in transaction cost economics (TCE). Second, to critically analyse and question the efficiency and effectiveness of various safeguarding approaches, which are taken for granted and commonly practiced in construction, from a lean perspective.

Design/methodology/approach

The analysis of this paper is based on an in-depth critical review of 76 construction procurement and contractual-related articles, ranging from 1994 to 2016, using theories of Lean construction and TCE as an analytical lens.

Findings

Findings reveal that clients and decision makers often tend to safeguard their project-specific assets, against opportunism and exploitation, through the deployment of formal contractual arrangements and governance structures. These arrangements and structures typically dominate the management of the project delivery often to the detriment of the project itself; but because there is a belief that interests are safeguarded, clients and decision makers feel they have taken the best course of action. This goes a long way to explaining the coherence of the current construction model.

Research limitations/implications

To the best of the authors’ knowledge, this paper is the first to demonstrate the usefulness of using principles of Lean construction in association with TCE when analysing construction-procurement-related issues. In particular, the use of a “lean” lens helps to expose the impact of procurement governance arrangements on process flow. The study also provides a potential research agenda that can lead to the development of prescriptive conceptual frameworks for causal analysis of institutionalised waste in construction.

Practical implications

The paper attempts to expose to clients and decision makers the amount of waste (and unnecessary cost) they embed by adhering to prevailing unfit-for-purpose contractual governance approaches. It also helps decision makers to consider alternative procurement arrangements and organisational techniques that could be of value and support collaborative ways of working.

Originality/value

The study contributes to the overall understanding of waste in construction by providing insight into various imperfect procurement and contractual arrangements, which are taken for granted and impede efficiency and improvement efforts in construction. The findings presented provide a theoretical anchor and rationale for developing alternative approaches to the design and delivery of capital projects.

Abstract

Purpose

This study has dealt with the gap in the literature, by probing the influence of innovation capability on business performance. This paper aims to test the moderation role of technological turbulence (TT) and market turbulence (MT) on the relationship between innovation capability (IC) and business performance (BP).

Design/methodology/approach

The study used a quantitative survey and a sample size of 579 departmental heads. Branch managers and permanent staff from the Greater Accra, Ashanti and Western Region in the Ghana telecommunication sector. The obtained data was analysed through the STATA 15.0 and AMOS statistical software package.

Findings

The empirical results from multiple linear regressions revealed that product/service innovation, process innovation, marketing innovation and administrative innovation had positive effects on business performance. The outcome of the moderation analysis further shown that technological turbulence positively moderates the relationship that existed between the various constructs of innovation capability and business performance indicating that technological turbulence significantly strengthens the relationship between these variables. On the contrary, market turbulence significantly weakens the relationship between the various innovation capability constructs and business performance.

Research limitations/implications

Although this research has made significant contributions to both theory and practice, there are certainly some limitations and future research directions that need to be considered to appropriately position the study findings. Firstly, because of the limited sample size (579), further testing of these constructs needs to be carried out in future research using alternative data. Related to this, it would be prudent if the instruments and models developed in this research were tested in different industry contexts. Also, because the Ghana telecommunication sector is made up of foreign companies, comparative research could be conducted to compare the IC and performance of Ghana and the other countries where these companies operate. Indeed, analyses of IC and BP associated with the same companies in different countries may prove to be very beneficial in the global context. Secondly, this research used only TT and MT to test the moderating effect of ET on the association of IC with BP. Future research can include competition intensity which may change or confirm the outcome of these studies. Thirdly, only qualitative data were used for the measurement of IC and the level of BP. Therefore, future research could use quantitative or both qualitative and quantitative data to confirm if there will be significant differences in the results obtained.

Practical implications

Literature has examined the moderation effect of ET on different variables and relationships in different organizational settings. This study has tried to analyse the moderating effect of ET on the relationship of IC with BP. The outcomes of this study are similar to the previous research studies mentioned above, however, limited studies have been conducted on IC and its relationship with BP in the context of ET especially in the most vibrant sector of Ghana’s economy. These findings are very innovative and contribute enormously to literature and knowledge by indicating which moderating ET positively and significantly strengthens and the type which weakens the existing relationship between IC and BP within the Ghanaian telecommunication sector which no researcher has conducted. These findings will go a long way by aiding the players in this sector to tauten their IC wings to achieve resilient performance around the globe.

Social implications

This will also contribute to the growth of Ghana’s economy as sources of revenue and employment. Additionally, the results obtained from this study will prompt managers to make more informed and effective decisions regarding innovation activities and the environments in which they operate.

Originality/value

This paper adds knowledge and literature to the existing ones. It is a new development in the research field of Ghana. This is the first journal this study has been submitted.

Abstract

Purpose

Work on construction sites involves individuals with diverse character, temperament,age, physical strength, culture, religion and experience level. A good number of these individuals are also alleged to involve themselves in substance and alcohol abuse due to the physically demanding nature of their work. These could promote the prevalence of violence on construction sites which could in turn affect safety on construction sites. However, there is a lack of empirical insight into the effect of violent behaviour and unsafe behaviour on construction sites. This study therefore pioneers an empirical inquiry into the relationship between violent behaviour and unsafe behaviour on construction sites.

Design/methodology/approach

Seventeen violent behaviours and 15 unsafe behaviours were measured on 12 construction sites among 305 respondents using a structured questionnaire. A total of 207 valid questionnaire responses were collected from site workers. Partial least square–structural equation modelling (PLS-SEM) technique was used to examine the relationship between violent behaviour and unsafe behaviour.

Findings

The results indicate that there is a significant positive relationship between violent behaviour and unsafe behaviour on construction sites.

Originality/value

The findings from this study provide valuable insight into a less investigated dimension of the problem of construction site safety management. A focus on attitudinal issues such as how workers relate toward others and toward self should be an important consideration in safety improvement interventions on construction sites.

Abstract

Purpose

Multilateral aid agencies generate most of their funds from taxpayers, and therefore, it is necessary to ensure that recipients or borrowers use the funds for the intended purposes. The World Bank is one of the major multilateral aid agencies that fund infrastructure projects in developing countries. Like other multilateral aid agencies, the World Bank uses oversight instruments/auditing tools to manage procurement risk on their funded projects. However, empirical insight about the effectiveness of these auditing tools is limited. This paper aims to assess the effectiveness of one of such multilateral aid agencies’ auditing tools (i.e. World Bank’s procurement post review [PPR]) in procurement risk mitigation on funded projects in a developing country context.

Design/methodology/approach

The study is based on secondary data obtained from the World Bank PPR reports carried out in the 2014, 2015 and 2016 financial years. Five projects with the highest loan amounts and five with the lowest loan amounts for the three-year period were selected from the 24 active World Bank projects during the time of the study. A purposive sampling technique was used to select a representative sample from a list of contracts under the 10 projects.

Findings

The results of the analysis showed a clear decline in the number of both major and minor deviations over the three-year period while an increase in the number of contracts with “No Deviation”. The study therefore concludes that procurement risk experienced a decline amongst the World Bank projects in Ghana where post reviews were carried out on yearly basis.

Originality/value

The study identifies the need for more frequent PPR and makes a case for the need to investigate whether PPR is a superior auditing tool compared to the other tools.

Abstract

Purpose

The purpose of this paper is to examine the views of construction practitioners on the prevalence of ethical misconduct within the invitation to tender and tender evaluation and award stages of construction contracts in Ghana.

Design/methodology/approach

Following a critical comparative review of literature resulting in the identification of 18 potential misconducts within the invitation to tender and 11 potential misconducts within the tender evaluation and award stages of construction contracts, a questionnaire survey was conducted among 65 construction professionals. Data obtained from the survey were analysed using both descriptive (i.e. frequencies, mean scores and standard deviations) and inferential statistics (paired t-test), followed by gap analysis.

Findings

The findings revealed that corrupt, fraudulent, collusive or coercive practices, client divulging more information to the preferred bidder and inflating tender prices by tenderers in return for kickbacks are key unethical practices prevalent at the invitation to tender stage. Following these key unethical practices, the findings further suggested through gap analysis that submission of bids on non-working days and inadequate time for preparation and submission of tenders were the top two unethical practices that needed serious interventions at this stage. At the tender evaluation and award stage, the findings revealed that interference by influential people in political positions, fake tendering and bid shopping are prevalent. Again, from the gap analysis, interference by influential people in political positions and poor definition of selection criteria were identified to be the two key unethical practices that need urgent intervention at this stage of construction contracts.

Practical implications

This study holds a significant practical implication in the sense that key unethical practices at the invitation to tender and tender evaluation and award stages of construction contracts have been identified, and this provides a suitable basis for stakeholders that spearhead such activities to offer suitable interventions to control such practices.

Originality/value

This study contributes to the body of knowledge as it uncovers ethical misconducts within two important phases of construction contracts in a developing country setting. As there is a continuous effort by the international community towards finding lasting solutions to such misconducts, the findings from this study can be used as a starting point for appropriate policies to be put in place in Ghana to control such misconducts.

Abstract

Purpose

Studies showed that construction consultants' ethical negligence is a contributing factor to the time and cost over-run of projects. There is limited research on the issues that may have hindered construction consultants' ethical responsiveness during contract administration. Studies regarding influencing factors in the context of Nigeria's quantity surveyors' (QS) ethical responsiveness are rare. Thus, the study aims to investigate the perceived issues and proffers initiatives to promote QSs' ethical responsiveness on construction projects in Nigeria.

Design/methodology/approach

To determine the perceptions of QS regarding ethical responsiveness, a phenomenologically driven perspective via face-to-face interviews was conducted with 12 senior professionals in Lagos and Abuja that showed interest in participating in the study and were interviewed. A thematic approach was adopted to analyse the collated data.

Findings

Economic, societal and professional issues emerged as the three groups of issues that hindered QS's ethical responsiveness on construction projects in a developing country setting such as Nigeria. Findings show that for ethical responsiveness to be expressed on projects, key stakeholders should be ethically responsible. This is currently missing, especially in public construction projects. Initiatives that can promote key stakeholders' ethical responsiveness on construction projects are examined in this paper.

Practical implications

The paper embraces an important practical implication because practices associated with QS's unethical responsiveness and behavioural impacts on construction projects were identified. This will stir both the regulatory professional bodies and policymakers to enforce and implement feasible initiatives that can promote key stakeholders' collaborative ethical responsiveness on construction projects.

Originality/value

This paper is amongst the few papers that attempted to uncover issues that hinder QS's ethical responsiveness on construction projects in a developing country setting via a qualitative approach. Since these issues are rampant in developing countries, findings from this paper can be used to promote QS's ethical responsiveness in other nations with similar unethical issues.
