Construction process is complex and traditionally fragmented; thus, it is almost impossible to have a project completed without changes to the original plan or the construction process. The purpose of this study is to identify and examine the causes of variation orders, ascertain their effects and establish the cost and time performance implication as a result of variation orders.

This study obtained information from 90 construction stakeholders on 30 completed educational building projects to ascertain the causes and effects of variation orders on project delivery using questionnaire survey. In addition to this, a pro forma document was designed to obtain the project characteristics, cost and time data from these 30 completed educational building projects. Factor analysis was used to categorise the causes of variation orders, while severity index was used to examine their effects on project delivery. The hypothesised statement was tested using paired t-statistics to examine whether a statistically significant difference existed between variation orders, cost and time performance of the projects.

The study identified 13 main factors as causes of variation orders and the results revealed that the most frequent effects of variations were increase in construction costs, time, client dissatisfaction, increase construction project rework and demolition and project abandonment. The results also showed that variation orders had significant effects on both cost and scheduled performance of the educational building projects with average cost and time escalation of 33.95 and 29.45 per cent of the original project cost and time, respectively, for the entire projects studied, while average cost implication of variation orders is 23.79 per cent.

The findings in this study will be of assistance to government agencies and management of public works in higher institutions of learning in managing variations in construction projects. The study will also add to the current literature on the impact of variation orders on educational building projects in developing countries. Finally, it will create the much-needed awareness on the severity and implication of change or variation orders on project delivery.

The study identified and examined the causes of variation orders, ascertained their effects and established the cost and time effects of the causes of variation order on project performance. This will assist project initiators, contractors, consultants and other stakeholders to fully appreciate and understand the significant effects of variation orders on project performance.

The purpose of this paper is to examine the possible moderating role of organisational characteristics (organisational structure, management style and decision-making style) in the relationship between strategy and organisational performance among large construction organisations in South Africa.

The study adopted a quantitative research approach using a questionnaire survey to obtain data from 72 large construction organisations in South Africa. Using hierarchical multiple regression, the paper examines the relationship between the constructs discussed in the study.

The internal characteristics of the organisation form the vital basis for achieving optimal performance. The results obtained from the analysis revealed that decision-making style directly influences the measure of organisational effectiveness, while it could also be inferred that organisational characteristics partly moderate the relationship between competitive strategy and organisational performance. The findings indicate that internal characteristics is one of the means through which organisational strategic factors and contextual aspects are organised to achieve greater organisational performance levels.

The findings have theoretical implications for strategic management literature in construction as it extends the scope of research on strategic management from assessing a set of individual management practices to evaluating a complex mechanism that connects internal characteristics and competitive advantage. It is believed that this study will contribute positively to the role of organisational characteristics in the competitive strategy-performance relationships in large construction organisations in South Africa and to the ongoing discussion on emerging strategic management issues in construction.

The purpose of this paper is to examine the influence of social media adoption on the performance of construction small and medium-sized enterprises (SMEs).

Construction SMEs owners and managers in Nigeria were surveyed using questionnaires to gather data. Partial least square structural equation modeling (PLS-SEM) was employed to assess measurement reliability and validity, as well as the hypothesized paths provided in the conceptual model that formed part of the final conclusions.

The empirical finding showed that social media usage increased knowledge accessibility, reduced costs and improved customer relations and service for organizations. Overall, social media adoption was significantly and positively related to SMEs business performance. Also, the paper revealed that learning capability mediates the relationship between social media and SMEs performance.

Data for the study came from only one industry and one related line of business; thus, including more companies from different sectors or industries could be more interesting. The study's findings contributed to the growing body of knowledge about the impact of social media on the efficiency of businesses. Small and medium-sized businesses also need to understand and recognize the impact of social media on the organization's performance in order to achieve a long-term competitive edge from the adoption of social media.

According to the findings, small construction firms can benefit from marketing the brands through social media channels and improved learning capability. In terms of accessibility, cost savings and improved relationships with customers, research shows that social media promotion can be beneficial to businesses. A study like this has the potential to show how social media can help striving small businesses interact cost-effectively with customers all over the world, opening new doors for sales and continuous improvement.

The relationship between SME performance in Nigeria and the use of social media has received very little attention despite social media's promising potentials, particularly for small businesses. The authors hoped that this study will fill a gap in the authors' understanding of how social media affects the performance of small and medium-sized businesses (SMEs) in the construction industry.

This study examined the causes of academic stress amongst undergraduate students in the Department of Quantity Surveying to ascertain whether stress has an influence on their academic performance.

This research explores the relationships between these constructs: academic stress, non-academic stress, coping strategies and academic performance, using a survey questionnaire to collect data from 190 undergraduate students in the Quantity Survey department. Descriptive statistics have been used to analyse the data and a path analytical approach has been adopted to evaluate the relationship between the constructs discussed in the paper.

Significant linear associations have been established between all the proposed paths and the outcome factor (p < 0.00). Coping strategies were an important mediator (p = 0.000), as they explained 32.9% of the association between academic stress and non-academic stress. However, the findings have shown that the stress faced by students is an optimal degree of stress that improves learning capabilities.

Explanation and clarification of the effects of academic and non-academic stress and coping mechanisms on the academic performance of university undergraduate students could help to reduce the risk of suicide amongst the teeming youths. It will also afford the university administration the opportunity to engender stress-free environment that is conducive for learning through the formulation of appropriate policies that promote “balanced learning” for the students. The outcome of this study may provide a launch pad for researchers who are interested in knowing how the possible causes of stress may impact on the health of university students.

The findings will be of great importance to the academic advisers and university administration in developing a flexible academic calendar and adopt policies that will eliminate academic stress and promote strategies to cope with non-academic stress. The study is the first attempt to examine academic stress, non-academic stress, coping strategies and academic performance in a single research in the Nigerian context due to limited literature found. This study has pedagogical implications to education practice by offering tertiary institutions the opportunity to appraise and device a means of managing students' stress by identifying their needs and increase students' coping skills based on prevailing modalities that give students' opportunities to strengthen the strategies of coping.

The purpose of this paper is to explore the mediating effect of learning capacity in the relationship between the social media usage by the construction of small- and medium-sized enterprises (SMEs) and their business performance in Nigeria.

A quantitative survey technique was used to collect data from the owner/manager of construction SMEs in Nigeria. The partial least square structural equation modeling was used in the assessment of the measurement model and structural model to assess the validity and reliability of the measures and to evaluate the hypotheses proposed in the conceptual model.

Empirical findings indicated a significant positive relationship between learning capacity and performance of SMEs. Similarly, the use of social media is significantly and positively associated to the business performance of SMEs. It has also been shown that learning capacity is a mediator of the relationship between social media and SME performance.

The data for the study is are all from a single industry and a related line of business, so it could be more interesting to include more companies across sectors or industries. The finding contributes to the ongoing debate on the effect of social media on business performance. It also defined the need for the owner/manager of SMEs to understand and appreciate the effect of social media through the organization's learning potential to gain a sustainable competitive advantage.

There are a number of theoretical and practical implications for academics and practitioners who are interested in further studies of organizational social media. The research presents a quantitative study on the effect of social media adoption on the organizational performance of the construction industry. This study confirms the mediating role of learning capability in the relationship between the use of social media and performance of SMEs operating in the construction industry.

This study empirically examined the relationship between social media adoption and the SMEs learning capability and business performance by evaluating a hypothesized conceptual framework to establish the relationships.

The study aims to identify and examine the construction organisational environments and its dimensions that have an impact on the performance of contracting companies in South Africa.

The study reports the result of quantitative research that obtained data from 72 construction organisations registered with the South African construction industry development board via a questionnaire survey. Descriptive statistics, non-parametric and exploratory principal component analysis were used to summarise forms of correlations among observed variables and to reduce a large number of observed variables to a smaller number of factors that provide an operational definition for the underlying dimension.

This study identified six exogenous and three endogenous environmental factors that have a varying degree of impact on construction organisation performance. Four dimensions of the environment were also examined, and environmental complexity has the highest variance explained which implies that the complexity of the construction business environment significantly influences the performance of construction firms.

This paper studies the environment of the South African construction industry using cross-sectional data in exploratory research. A confirmatory study should be conducted using a longitudinal panel design with a larger sample in similar future research.

The study offers practical implications to construction organisation owners operating in the South African construction industry to understand the need to acquire market and environmental data and process them in a way that will reduce its uncertainty when making strategic decisions.
