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.

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.

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.

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

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.

Over dependence on river/sea sand as building material has impacted the environment negatively. However, laterite, which is an environment-friendly indigenous building material in sub-Saharan Africa, has been less exploited as a suitable alternative. This paper aims to ascertain the optimum cement–laterite mix proportion at which laterite can be stabilized for production of walling units.

Using an experimental method, laterite was collected from three borrow pit sites. Sieve analysis was performed to determine the particle size distribution. Also, the degree of workability of the cement–laterite mix was ascertained using slump test. Compressive strengths were determined at cement stabilization percentages of 3%, 7% and 10% on 12 cubes of100 mm cast and cured for 14 and 28 days, respectively.

The results showed that the lateritic soil investigated, achieves its optimum strength in 28 days of curing, at a stabilization level of 10%. An average compressive strength of 2.41 N/mm2, which is 20.5% greater than the target strength, was achieved.

To meet the desired compressive strength of alternative walling units while achieving environmental sustainability and efficiency in production, cement stabilization of lateritic soils should become a recommended practice by built environment professionals in sub-Saharan Africa.

This paper is one of the first research works that attempts to determine the optimum level at which the abundant sub-Saharan laterite can be chemically stabilized for the production of non-load bearing walling units. This research promotes an environment-friendly alternative building material to sea sand, river sand and off-shore sand.

The purpose of this paper is to identify the risks associated with private sector participation (PSP) in power generation (PG) projects, how they were allocated and the strategies used to mitigate their likely adverse effects.

The paper adopts case study research method and cross-case analyses to unearth the key risks and the contractual instruments used to manage them.

The paper identified 30 risk factors associated with four major private sector PG projects in Ghana. The allocation and mitigation strategies of these risks are also reported.

This is the first study to create a risk register of PSP PG projects. Private investors and government have been provided with a comprehensive list of risks associated with PG infrastructure. Would-be investors have also been armed with some potential risk management strategies for proper project structuring.

This study aimed at developing and empirically testing a system dynamics causal loop (SDCL) model for investigating factors related to the risk of cost overruns, associated with the performance of construction projects in developing countries.

Using data derived from the Ghanaian construction industry (GCI), a conceptual system dynamics model was hypothesised and empirically tested.

Supported by empirical evidence, the study established that the low technical capacity of consultants is the underlying cause of cost overruns in government projects. There is a strong proof of the relationship between the results of the SDCL model and poor contract planning and supervision, change orders, competence of the project team and the lack of effective coordination amongst the contractual parties.

The final SDCL model has revealed key risk components that would require standard mitigation measures in order to achieve “acceptable success” in construction projects.

The study presents an interactive approach for construction practitioners in developing countries to prioritise the causes of cost overruns in order to initiate quick responses.

The purpose of this paper is to explore the various approaches prescribed in literature in the assessment of value for money (VfM) of public–private partnership (PPP) projects with the aim to develop a theoretical framework for measuring VfM in Ghana.Public–private partnership (PPP) has long been recognized as an effective way of procuring public infrastructure to deliver value for money, but the subject has received little research attention in Ghana.

The methodology comprises a multi-stage critical review of relevant literature; review of Ghana’s National Policy on PPP and review of the Public Procurement Act, 2003 (Act 663). This paper was underpinned by an interpretivist philosophy and is inductive in nature.

The approach for VfM assessment largely depends on the jurisdiction of the project. Multiple methods (qualitative and quantitative) are used along the project cycle in the bid to achieve VfM. The most common assessment approaches include public sector comparator shadow bid, lease-purchase analysis, cost benefits analysis, public interest test central guidelines and competitive bidding. The study developed a theoretical framework for assessing VfM in Ghana.

The research was purely exploratory and non-empirical; and hence cannot be generalized in a broader context.

Implementation of the National PPP policy and for PPP to thrive in Ghana, a framework to guide the assessment and achievement of VfM is crucial. The steps outlined if followed would help ensure the public receives the best of all PPP deals in Ghana.

This paper is unique providing insights into a conceptual basis for assessing VfM and provides a basis for future empirical study.

Corruption continues to be a pervasive stain on the construction industry in developing countries worldwide, jeopardising project performance and with wide-ranging negative implications for all facets of society. As such, this study aims to identify and analyse the causes of corruption in the construction sector of an emerging economy such as Malaysia, as it is crucial to uncover the specific facilitating factors involved to devise effective counter strategies.

Following a detailed literature review, 18 causes of corruption are identified. The results of an opinion survey within the Malaysian construction industry are further reported to rank and analyse the causes. The factor analysis technique is then applied to uncover the principal factors involved.

The results indicate that all the considered causes are perceived to be significant, with the most critical causes being avarice, relationships between parties, lack of ethical standards, an intense competitive nature and the involvement of a large amount of money. A factor analysis reveals four major causal dimensions of these causes, comprising the unique nature of the construction industry and the extensive competition involved; unscrupulous leadership, culture and corruption perception; a flawed legal system and lack of accountability; and ineffective enforcement and an inefficient official bureaucracy.

The study presents the Malaysian construction industry’s view of the causes of corruption. Therefore, the arguments made in the study are influenced by the social, economic and cultural settings of Malaysia, which may limit generalisation of the findings.

This paper helps stakeholders understand the root causes and underlying dimensions of corruption in the construction industry, especially in Malaysia. Recommendations for changing cultures that may be conducive to corrupt practices, and anti-corruption measures, are suggested based on the findings of the research.

These findings can guide practitioners and researchers in addressing the impediments that give rise to the vulnerability of the construction industry to corrupt practices and understanding the “red flags” in project delivery.

Project scope creep is a nightmare and nearly intolerable task. Most project managers struggle to curtail the expanse and degree of scope creep. This study examines different likely project scope creep factors associated with the construction industry projects.

After many brainstorming sessions with construction stakeholders, several project scope creep factors were identified. Then, a detailed survey was executed in big construction projects of the United Arab Emirates (UAE). The data were analyzed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).

The results derived and validated five conspicuous factors leading to project scope creep. Respectively, the highest and the lowest impact on project scope appears to be imposed by tasks/specifications and complexity/uncertainty.

It offers crucial support to the project stakeholders in scrutinizing different factors that stand as hurdles to project success and allows them to seek remedies to resolve them.

It is among the first study in the region that identifies and validates the factors that hinder construction project success.

The quest for improved facilities management (FM) delivery is receiving immense focus through the incorporation of innovative technologies such as cyber-physical systems (CPS). The system’s high computational capabilities can aid in the abatement of some of the challenges plaguing FM functions. However, the requisite ingredients for the uptake of the system for FM have still not gained scholarly attention. Because performance measurement is a vital index in determining the outcome of FM methods, this study aims to investigate the influence of performance measurement indicators that are influential to the uptake of CPS for delivering FM functions.

A qualitative technique was adopted using the Delphi technique. The panel of experts for the study was selected through a well-defined process based on stipulated criteria. The experts gave their opinions in two rounds before consensus was attained on the identified performance measurement indicators, whereas methods of data analysis were measures of central tendency, inter-quartile deviation and Mann–Whitney U test.

Results from this study showed that 11 of the performance indicators were of very high significance in the determination of the uptake of CPS for FM functions, whereas 5 of the indicators were proven to be of high significance. Furthermore, there was no statistical difference in the opinions of the experts based on their affiliation with academic institutions and professional practice.

The findings of this study contribute practically by aiding policymakers, facility managers and relevant stakeholders with the vital knowledge of delivery mandates for efficient FM services that can spur the uptake of digital technologies such as CPS.

This study contributes to the body of knowledge as it unveils a roadmap of the expected performance output and its accompanying evaluation that would drive the adoption of a promising technology such as CPS in the delivery of FM tasks.

Using the institutional and natural resource-based view theories, the purpose of this study is to examine the influence of religious, cultural and mimetic orientations on proactive environmental strategy, corporate environmental responsibility and traditional environmental strategy. Relying on data collected from managers of small and medium-sized enterprises (SMEs), the study further examines how proactive environmental strategy, corporate environmental responsibility and traditional environmental strategy drive relational capital and firm performance of SMEs operating in Ghana.

The study employed a survey research design, a quantitative approach and a partial least square structural equation modelling technique in making data analysis and interpretations due to its appropriateness for predictive research models.

The results suggest that mimetic orientation robustly and significantly influence the dimensions of environmental orientation. While religious orientation only had a robust and significant influence on proactive environmental strategy, cultural orientation robustly and significantly influences both proactive and traditional environmental strategies. Despite the positive and significant interactions that exist between proactive environmental strategy, corporate environmental responsibility, traditional environmental strategy, relational capital and firm performance, the findings particularly revealed that proactive and environmental strategies insignificantly correlated with relational capital contrary to past study findings.

The study is among the few to examine how religious, cultural and mimetic orientations interrelate with proactive and traditional environmental orientations, relational capital and firm performance in an emerging economy. Based on the findings, implications and directions for future research are discussed while also providing guidance for policymakers, regulatory bodies, scholars and practitioners.

In Ghana, the duration of construction projects from inception to completion is becoming a great concern, recently, especially among clients and beneficiaries, because of the rising interest rates, inflation, development plan targets, among other factors. Hence the need to understand the causes of delays and cost overrun in the construction sector has become more important than ever. This study therefore aims to identify the major factors underlying time and cost overruns in projects related to the education sector in Ghana to proffer practical solutions in addressing them.

The study conducted a survey among clients’ consultants and representatives of the contractors working on about 60 government school projects. A relative importance index was used to determine the relative effects of the factors causing construction time and cost overruns.

The key factors causing construction time overrun were: financial problems, unrealistic contract durations imposed by clients, poorly defined project scope, client-initiated variations, under-estimation of project cost by consultants, poor inspection/supervision of projects by consultants. Other factors were underestimation of project complexity by contractors, poor site management, inappropriate construction methods used by contractors and delays in the issuance of permits by government agencies. Factors affecting cost overruns were financial difficulty by client, delays in payments of completed works, variations in designs, lack of communications plans, poor feasibility and project analysis, poor financial management on site and material price fluctuations.

The research was limited to only the educational sector projects.

Practically, this study highlights for the construction sector the critical factors causing project time and cost overruns in Ghana. Identification of these factors provides the basis for pragmatic solutions to enhance the chances of project success.

The identification and solutions to project time and cost overruns, especially for educational sector projects, contribute toward making public goods more affordable and accessible to most citizens, particularly in developing countries.

This study contributes to the debate on factors causing project time and cost overruns in the construction sector especially from a developing country’s perspective.
