The purpose of this study is to investigate the challenges of pricing quantity surveying (QS) professional services to enhance the understanding of practitioners in developing strategies for the determination of fees for their services.

The paper adopts the quantitative approach by administering 150 survey questionnaires QS professionals out of which 79 questionnaires were retrieved for analysis using the mean, standard deviation, standard error and the Chi-Square test.

The study identified the challenges that continue to hamper the successful pricing of QS services as the inability to respond to changing contractual arrangements; lack of appropriate response to emerging services; slow response to changes in information and communication technology.

This paper focused on QS professionals. Hence, a future study to encompass other professionals in the built environment will be novel.

The findings of this paper have the potential to motivate QS firms to develop solutions that address the challenges identified to improve the efficiency of their service delivery to clients. The paper also has the practical importance of opening up new frontiers of research that focus on pricing of professional services in the built environment in general.

The paper contributes to the awareness and understanding of QS professionals about the challenges that continue to hamper effective pricing of their services.

To be able to achieve the uptake and usage of green buildings requires various actors within the construction value chain to be engaged. Despite its global uptake, green building construction is still at its nascent stage in Ghana. Most studies in sub-Saharan Africa point to the lack of knowledge as one of the mitigating factors against its development. However, there is a dearth of studies assessing the level of knowledge of stakeholders. The terms “knowledge” and “awareness” of green building construction are often used interchangeably in the Ghanaian Construction Industry (GCI). This study seeks to unearth the level of knowledge of stakeholders on green building construction through a comparative analysis of construction professionals and demand-side operators.

A structured questionnaire was issued to professionals in the various recognised bodies in the construction industry and public and private institutions in Ghana. Frequency, Kolmogorov–Smirnov test, median statistics and Mann–Whitney U-Test were used to rank and analyse the level of knowledge of stakeholders.

Construction professionals were more aware of green building construction than the demand-side operators. It was further identified that only a few of these stakeholders had hands-on experience as the majority of them have gained their awareness through research studies. Based on the findings of the study, it was revealed that the concept of green building construction is more abstract to stakeholders than practical despite their positive attitude towards its adoption.

Contextually, the study has aided in showing the level of knowledge of stakeholders on green building construction. The findings of the study aside from it aiding policymakers have also helped in identifying the perceptions and attitudes of stakeholders, their strengths and weakness in green building construction. It is recommended that due to the differences in socio-political structures and construction methods, a clear definition of green building based on the availability of resources in the GCI will encourage its adoption.

The study used two stakeholder groupings in the GCI as the unit of analysis. This enabled insightful discoveries into the knowledge-attitude gap of Ghanaian stakeholders that are driving the adoption of green building.

E-procurement has the advantage of improving the overall performance of construction project delivery. The purose of this study is to uncover the factors influencing e-procurement acceptance in the public sector of Ghana’s construction industry (GCI). Using an extended unified theory of acceptance and use of technology (UTAUT 2), variables that promote the acceptance of e-procurement in GCI were explored.

Data was collected using a mixed method strategy. In the first stage, a semi-structured interview was used to collect, assess and optimize the UTAUT2 model. Thematic analysis was used on the qualitative data, leading to modification of the proposed UTAUT2 model. The study subsequently used a questionnaire survey using the extended UTAUT2 model. Survey data was analyzed using structural equation modelling (SEM), leading to the identification and validation of factors that facilitate e-procurement acceptance in Ghanaian construction as well as the impact of these factors.

The findings of the study reveal that five independent constructs of the proposed UTAUT2 model significantly affects the behavioural intention of practitioners to accept and use e-procurement in the construction industry in Ghana.

The study will be of utility to government agencies, contracting organizations and other construction stakeholders in developing policy and programmes to support e-procurement acceptance within the sector.

This is a new extended UTAUT2 model that is applicable to technology acceptance within the public sector in sub-Saharan Africa.

As public–private partnerships (PPPs) have become preferred and veritable approach to deliver affordable housing, the seemingly lack of understanding of the significant factors that impact on success has become a notable setback. This study aims to delineate significant factors that can support decisions in affordable PPP public housing delivery.

Largely, a questionnaire survey was adopted to elicit insights from practitioners, policymakers and experts to develop an evaluative decision support model using an analytical hierarchy process and multi-attribute utility technique approach. Further, an expert illustration was conducted to evaluate and validate the results on the housing typologies.

The results revealed that energy efficiency and low-cost green building materials scored the highest weighting of all the criteria. Furthermore, multi-storey self-contained flats were found to be the most preferred housing typology and were significantly influenced by these factors. From the model evaluation, the scores on the factors of sustainability, affordability, cultural values and accountability were consistent across all typologies of housing whereas that of benchmarking, governance and transparency were varied.

The decision support factors captured varied dimensions of key factors that impact on affordable PPP housing that have not been considered in an integrated manner. These findings offer objective and systematic support to decision-making in affordable PPP housing delivery.

The link between relationship typologies and effectiveness of conflict resolution approaches remains to be tested despite its significance in conflict management in construction project delivery. By using the four relationships attributes based on the group attachment theory, the purpose of the study was to explore the cluster of relationships among project teams and organisations and the performance of conflict management strategies across these clusters in the Ghanaian construction industry.

Using a deductive questionnaire survey in the Ghanaian construction industry, a total of 137 responses were gathered and analyzed using cluster analysis, mean scores and ANOVA to reveal the relationship clusters and performance of conflict management strategies across these clusters.

The results revealed eight relationship clusters that exist among project teams and organisations with distinct influence of roles & tasks function, cognition, emotions and behavior attributes across the relationship clusters. In the aspect of the effectiveness of conflict management strategies, it was noted that the performance of these strategies were significantly different across the groups. For instance, integrating as a conflict management strategy was deemed to be effective in resolving conflict in unitary, adversarial, pluralist, mutuality, collaborative and partnering relationship clusters. In the case of coopetitive and coercive relationships, the performance of integrating as a conflict management strategy was less effective. This study thus has empirically proved that, different relationship clusters of teams and organizations exist within the Ghanaian construction industry, and that they perform different roles & tasks functions, cognition, emotions and behavioural attributes in their formation. Additionally, the performance effectiveness of conflict management strategies differed across the relationship clusters.

By aligning the relationship attributes to the dynamics of relationship clusters experienced in project teams and organisations, relationship quality, suitability and effectiveness of conflict management strategies can be optimized. The findings can inform project teams and stakeholders to develop fit-for-purpose relationship attributes among teams and organisations to enhance team effectiveness, relationship quality and conflict management in the industry.

Developing countries in sub-Saharan Africa are faced with significant challenges as the economies continue to emerge. There is a huge infrastructural demand and various efforts to step up supply. Whilst stepping up the supply, the environmental concerns of these supplies require a lot of attention. With the need to reduce the environmental impact of buildings whilst promoting a green infrastructure, various studies have explored the obstacles to green building technology adoption. This study explores the impediments to the development of the green building market in sub-Saharan Africa.

Using building consultants as the unit of analysis, this study explores the impediments using a structured survey questionnaire. The study area is Ghana, an emerging country in sub-Saharan Africa.

Key impediments to the development of the market is lack of awareness, lack of education and lack of fiscal incentives. The analysis shows that all the variables identified are significant in impeding the growth of the market. The results suggest that within the domain of developing countries, environmental issues may not be of immediate concern as economic issues take centre stage. For sustainability of the environment, it is unequivocal that dissemination of knowledge to key stakeholders be done.

Academic institutions and professional bodies have a pivotal role to play in raising awareness of green buildings. Governmental support such as various structures should be put in place to build up the local capacity of firms not only to compete with foreign counterparts but also to ensure innovative delivery of green buildings.

The paper presents contextual realities on the green market restrictions within developing countries in sub-Saharan Africa through a deeper understanding of market barriers and recommends pathways for stakeholders.

Building information modelling (BIM) and augmented reality (AR) are unique technologies in the digitalized construction industry. In spite of the numerous benefits of BIM-AR, its adoption has been at a relatively slow pace. The purpose of this study is to investigate how the factors within technology–organization–environment (TOE) framework influence the adoption of BIM-AR in the context of construction companies in a developing country.

By using a mainly deductive quantitative design, survey data were collected from senior management of built environment companies in Ghana using questionnaires. The study adopted a mixture of both purposive and snowball sampling approaches. Partial least squares structural equation modelling was used to analyse how the factors within the TOE framework explain BIM-AR adoption in Ghana.

Findings from the study show that the top three factors within the TOE framework that facilitate the adoption of BIM-AR include ICT infrastructure within construction firms; the size of the construction firm, which may influence the financial capacity to accommodate BIM-AR; and competitive pressure. The inhibitors of BIM-AR at the company level included external support and trading partners’ readiness.

Implicit is that the significant factors will be useful to policymakers and companies in developing programs that appeal to non-adopters to aid in mitigating their challenges and further enhance BIM-AR adoption.

The value of this paper has been the use of the theoretical framework TOE to explain the adoption factors of BIM-AR in the Ghanaian construction industry. The originality of the paper is further anchored in consideration of BIM-AR, which is quite nascent in emerging countries.

The purpose of this paper is to empirically study the factors that facilitate adoption of building information modelling (BIM) among quantity surveyors (QSs) using the unified theory of acceptance and use of technology (UTAUT).

Using a quantitative approach, factors identified in the UTAUT are examined. The empirical investigation has been conducted using survey questionnaire. The data set has been obtained from 73 practicing QSs in Ghana.

The results indicated a significant positive impact of effort expectancy, facilitation conditions and hedonic motivation towards BIM adoption. Surprisingly social influence and performance expectancy have a negative impact on BIM adoption.

The structures uncovered in the study show that not all UTAUT factors are applicable within the study area. The findings provide a good backdrop in the development of policy and a roadmap for BIM implementation in Ghana.

The original contribution and value of the paper is the use of UTAUT2 to provide empirical evidence on factors that facilitate BIM adoption in Ghana amongst QSs.

The construction industry is one of the most hazardous working environments globally. Studies reveal that wearable sensing technologies (WSTs) have practical applications in construction occupational health and safety management. In the global south, the adoption of WSTs in construction has been slow with few studies investigating the critical drivers for its adoption. The purpose of this study is to investigate the factors driving WSTs adoption in Ghana where investment in such technologies can massively enhance health and safety through effective safety monitoring.

To meet the objectives of this study, research data was drawn from 210 construction professionals. Purposive sampling technique was used to select construction professionals in Ghana and data was collected with the use of well-structured questionnaires. The study adopted the fuzzy synthetic evaluation model (FSEM) to determine the significance of the critical drivers for the adoption of WSTs.

According to the findings, perceived value, technical know-how, security, top management support, competitive pressure and trading partner readiness obtained a high model index of 4.154, 4.079, 3.895, 3.953, 3.971 and 3.969, respectively, as critical drivers for WSTs adoption in Ghana. Among the three broad factors, technological factors recorded the highest index of 3.971, followed by environmental factors and organizational factors with a model index of 3.938 and 3.916, respectively.

Theoretically, findings are consistent with studies conducted in developed countries, particularly with regard to the perceived value of WSTs as a key driver in its adoption in the construction industry. This study also contributes to the subject of WSTs adoption and, in the case of emerging countries. Practically, findings from the study can be useful to technology developers in planning strategies to promote WSTs in the global south. To enhance construction health and safety in Ghana, policymakers can draw from the findings to create conducive conditions for worker acceptance of WSTs.

Studies investigating the driving factors for WSTs adoption have mainly centered on developed countries. This study addresses this subject in Ghana where studies on WSTs application in the construction process are uncommon. It also uniquely explores the critical drivers for WSTs adoption using the FSEM.

This study aims to assess the awareness and knowledge level of procurement officers (POs) in Ghanaian tertiary educational institutions regarding sustainability in general and specifically on environmental sustainability in the Public Procurement Act 2003 (Act 663) as amended.

Through purposive sampling technique and face-to-face interviews using semi-structured open-ended questions, qualitative data was collected from 19 POs who are well vested in the procurement profession and willingly agreed to partake in the research. The qualitative data were analyzed using content analysis technique to help organize and elicit meaning from the data collected and to draw realistic conclusions from it.

The results showed that most POs were aware of the Public Procurement Act 2003 (Act 663) as amended, primarily through seminars and workshops organized by the Public Procurement Authority. The interviewees demonstrated a good understanding of sustainable procurement, considering its social, environmental and economic aspects. However, one respondent primarily associated sustainability with only environmental issues. The POs were, however, of the view that the Amended Act 914 (2016) does not give detailed highlights on environmental sustainability, making implementation very difficult, especially regarding the procurement of goods. Overall, the findings indicate a positive level of environmental sustainability awareness and knowledge among the interviewed POs regarding the Public Procurement Act 2003 (Act 663) as amended.

The findings from the study could be used by policymakers to strategize educational campaigns by using the POs’ knowledge and awareness to the implementers of Act 663 (2003) as amended to effectively ensure environmental sustainability in procurement practices. The findings from the study have also contributed to the literature on procurement policy by drawing the attention of policy formulators to give equal attention to all the sustainability pillars, i.e. social, economic and environmental. This would consequently help the implementers to contribute to achieving sustainable development.

This study is one of the few empirical qualitative types of research seeking the views of POs in tertiary educational institutions in Ghana on sustainability and environmental sustainability as enshrined in the Public Procurement Act 2003 (Act 663) as amended. The findings give positive feedback to policymakers on the knowledge and awareness level of the POs on environmental sustainability and highlight the importance of awareness programmes and educational initiatives by the Public Procurement Authority and other stakeholders to ensure compliance with the Act.
