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.

Firms in the architectural, engineering, construction and operations (AECO) sector continue undertaking projects in a disruptive environment due to the coronavirus disease 2019 (COVID-19) pandemic. This study aims to explore environmental turbulence in the AECO project delivery space and suggest mechanisms for enhancing resilience against future pandemics.

The study adopts the quantitative approach by administering 110 survey questionnaires to participants comprising project managers, site engineers, quantity surveyors, contractors and subcontractors.

The study identifies 24 COVID-19 disruptions linked to environmental turbulence categorised as scheduling, performance and productivity, project budget, supply chain, resource allocation and technological and regulatory. The study suggested resilient mechanisms for surviving in future pandemics.

This study enhances the understanding of environmental turbulence from the perspective of COVID-19 disruptions in AECO project delivery, while the implementation of the resilient mechanisms improves capability of AECO firms against future pandemics.

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.

Professional quantity surveying (QS) services are critical to successful delivery of construction projects within planned budget, quality and duration. The supply of QS professional services is largely dependent on the price level of services and the willingness of clients to pay. The pricing of professional QS consultancy services has been confronted with a myriad of pricing challenges due to rapid changes in the business environment; the pervasive influence of information technology; and the complexity of clients’ expectation. It is therefore necessary for QS consultancy firms to develop strategic competences for the pricing of their services. In addition, numerous studies have not given the pricing the pricing of professional services the requisite attention. The purpose of this paper is to investigate the strategic competences for pricing professional QS services.

The study was positioned within the positivist tradition. As a result, the quantitative approach was adopted using a survey questionnaire to collect data from QS consultants. The sample size of the study was 79 professional quantity surveyors chosen by using simple random sampling technique from a population of 372 registered professional QS of the Ghana Institution of Surveyors. Using the χ² test and factor analysis, the study established relationship between strategic competences and pricing of QS services.

The study found that strategic competences for pricing QS professional services is significantly related to the managerial and professional competence of QS consultants. The strategic competences of QS consultants identified by this study include business management, services cost management; and production capabilities.

This study provides an empirical basis for QS consultancy firms to focus on strategic direction of their contractual arrangement with clients. Practically, resource configuration and on strategic competences for professional service pricing would create price leadership.

The study advances the pricing knowledge within the QS practice by demonstrating the nexus between strategic competences and the pricing of QS professional services which hitherto this study have not been effectively investigated.

Notwithstanding that numerous studies have focused on strategy in quantity surveying (QS) professional service firms, there is a paucity of investigation on the segmentation of QS professional services. The purpose of this study is to investigate the segmentation of QS services for diversification and a focus strategy formation.

This study adopts the positivist stance and quantitative approach in which a simple random sampling technique was used to select participants. In total, 110 survey questionnaires were administered to registered professional QS, out of which 79 completed questionnaires were returned for analysis.

The paper identifies three main QS service segments characterised by low, moderate and high competition. In addition, this study found that the concentration of traditional QS services in the building construction sector is due to the unwillingness of QS professional service firms to diversify into the non-construction sectors such as oil and gas. The diversification of QS services in the low competitive segment requires the adoption of agile approaches.

The study was limited to numeric analyses and so would be complemented by qualitative research in the future.

This paper is useful to QS professional service firms interested in diversifying their services into the non-construction sectors to enhance the pricing of their services.

Segmentation of QS services is fundamental to the formulation of focus strategy for non-construction sectors such as oil and gas and mining to enhance the pricing of QS professional services.

This paper explored the socioeconomic factors affecting green cities development. Extant literature have highlighted green cities as a major path towards sustainability in the construction industry but very little is known on the socioeconomic aspect of green cities and its bid in promoting sustainability in the construction industry; hence, the premise of this study which highlights the socioeconomic factors affecting green cities development in Ghana.

A comprehensive literature review was conducted to identify the socioeconomic factors affecting green cities. A quantitative research strategy was adopted to collect primary data from respondents who have the requisite understanding and knowledge in green cities using questionnaires. The data gathered was then analysed using descriptive statistics and exploratory factor analysis viz principal component analysis.

The socioeconomic factors affecting green city development comprised: Green support mechanisms (i.e. innovation and technology, green city planning (urban planning), stakeholder engagement, awareness, city planning (transportation) and environmental regulations); green inhibitors (i.e. population, culture, housing and policy implementation); green market and finance (i.e. digital finance, green market mechanism, green investment finance, risks and uncertainties, income levels of clients). It was evident that socioeconomic factors are significant to the development of green cities in Ghana and hence policy makers and various stakeholders should prioritize socioeconomic factors in the bid to achieve sustainability through green cities in the construction industry.

This paper presents a foremost and comprehensive study on the socioeconomic factors affecting green cities in Ghana. The study results showed that even though the path to sustainability in green cities has pivoted mainly on environmental factors, socioeconomic factors are also significant to green city development, hence, policy makers and the construction industry should keenly consider the socioeconomic factors affecting green city development in the bid towards sustainability for cities.

Works procurement performance is critical to successful project delivery. However, early supplier involvement (ESI) has been touted in other industries to impact procurement performance positively. Works procurement has been attracting significant attention from major players due to poor performance characterized by poor performance, budget overruns and incompetence. Hence, the purpose of this study was to assess the impact of ESI on public works procurement performance.

Based on a thorough review of the literature for a pilot survey, the main questionnaires were administered to 103 public procurement officers. To assess the impact of ESI on public works procurement performance, three constructs that served as factors for implementing ESI and five that measure works procurement performance were validated using partial least square structural equation modelling (PLS-SEM).

The outcome of this study shows a significant positive impact of ESI on works procurement performance. This included communication, trust and supplier capabilities. The study further showed that even though cost, schedule, quality, health and safety are essential, sustainability measures are also crucial for work procurement.

The results of this study could help firms make better decisions regarding public works procurement by encouraging ESI. This will likely significantly impact the successful project delivery and preservation of sustainability and efficiency objectives.

The application of PLS-SEM analysis in this study provides insights into how ESI can impact the procurement of public works in Ghana.

The demand for energy infrastructure projects has increased steadily over the last few decades and has come at a high cost. Disruptive technologies (DTs) have the inherent capability to affect the performance of energy infrastructure projects. Therefore, this research aims to explore the implications of DTs on the performance of energy infrastructure projects.

This research adopts a positivist philosophical position. A quantitative strategy and deductive approach (based on a survey design) guided this study. Sixty-six respondents participated in the study. The study’s population comprised of experts in energy infrastructure projects who possessed a high level of industrial experience including top- and middle-level management of power generation companies. Cochran’s formula was used to select a sufficient sample for the study. Linear regression, one sample test and Cronbach’s alpha were the analytical tools adopted.

This study established that there is an 18.4% increase in the performance of energy infrastructure projects in Ghana when DTs are applied. In order of importance, DTs improve speed of operations in energy projects; reduce operating cost and enhance efficiency of energy projects; drive sustainable economic development; enhance security in energy projects; and improve environmental sustainability of projects. The study also revealed that e-commerce technologies, renewable energy technologies, three-dimensional printing, bar code technology, photogrammetry, global positioning systems, geographic information systems and nanotechnologies were the topmost ranked DTs with the most impact on the performance of energy infrastructure projects.

This is a novel investigation on the implications of DTs on the performance of Ghanaian energy infrastructure projects. This study’s practical implication is evident in both policy and practice. Energy sector policymakers should endeavour to adopt DTs in their operations to enhance sustainability and performance.

Despite the amount of considerable investigations on business models, much studies have not been undertaken in the construction industry emphasising the adoption of green business models to drive sustainable construction. Construction activities continue to increase the carbon footprint and eject contaminated materials into the ecological environment with dire consequences for economic and social sustainability. As a result of the adverse impacts of construction activities, it is necessary for construction firms to rethink their approach to the use of conventional business models. The purpose of this study is to explore a framework for the adoption of green business models to drive sustainability in the construction industry of Ghana.

This research is exploratory due to its focus on emerging economies in which there is a perceptible gap in the adoption of green business models. As a result of this, this paper is entrenched in the interpretivist philosophical stance, which led to the adoption of the qualitative approach. Semi-structured interviews were undertaken involving 13 senior managers of construction firms. A thematic analysis was used with the aid of qualitative data analysis computer software package to code the interview transcripts.

The results demonstrate the six definitions of green business models among the managers of construction firms. The study also shows the need for developing green business models to address the issues of circularity and sustainability goals to reduce carbon footprints in the construction industry. Similarly, the paper found various sources of information to drive the awareness, understanding and adoption of the components for green business models. These sources include international conferences and training workshops on green business models. Finally, the study presents a framework that integrates the building information modelling (BIM) and the Internet of things (IoT) into the components for green business models adoption in construction firms.

There is a need to use the quantitative approach to undertake further empirical studies, as this paper focuses mostly on the qualitative approach to ascertain the nature of the relationship between green business model and the various components of the circular economy in the construction industry.

The study contributes to the existing knowledge on green business models by demonstrating six key pillars of green business models by the inclusion of digital technologies such as BIM and IoT, which hitherto this investigation have not been considered in the adoption of green business models in the construction industry. This study extends the existing knowledge on green business models, which has the potential to increase the awareness and understanding of practitioners and managers of construction firms.

Price fairness is important amongst construction and engineering consultants because a perceived lack of it engenders unwillingness to pay amongst clients. This can create contractual disputes that negatively impact upon a consultant’s ability to generate sufficient revenue to ensure business continuity and survival. With this in mind, this research aims to analyse the pricing measurement forces needed to attain pricing fairness within a Ghanaian construction cost consultancy practice. Specific objectives are to identify the key variables responsible for price fairness within cost consultant services and to establish any interrelationships between them.

This study leans towards the positivist methodological tradition by adopting a quantitative approach. A survey questionnaire was distributed to a random sample of 79 construction cost consultancies, drawn from a population of 372, who were registered with the Ghana Institution of Surveyors. Hypotheses developed from the literature review were then tested on data collected.

The analysis revealed that fairness of construction cost consultancy services pricing is significantly related to value and affordability, pricing objectives, pricing strategies, taxes and international trade and its effects on inputs for construction cost consultancy services.

The paper advances knowledge by providing a basis for the consideration of pricing forces in the valuing of construction cost consultancy services which hitherto has not been the case.
