  • Description: Abstract: One of the key roles of construction project managers is to execute construction projects within the targeted project cost. In Africa, most construction projects suffer huge cost overruns. Project cost control practice is required by every construction firm to keep the project cost in line with the budgeted cost. A comprehension of the different parts of cost control philosophies is fundamental to empower project cost managers to adequately set up robust cost controls and to improve future strategies for active construction project cost delivery. Although there are efforts by project cost managers to control cost, there is a lack of understanding of the factors that determine cost control practice in Ghana, as a developing nation. The factors enhancing cost control practice and a formal model are needed for consideration by project cost managers to guide their operations. This study develops a model for predicting cost control practice in the Ghanaian construction industry. Mixed-method methodology was utilised for this study. The qualitative survey used the Delphi survey approach to investigate the primary factors and measurement-related factors. The study identifies project cost control as eight-factor constructs: project cost estimation, project cost budgeting, project cost reporting, project cost monitoring, project cost analysis, decision-making, change management and project cost communication. These had strong inter-quartile deviations. .. , D.Phil. (Engineering Management)

  • Description: D.Phil. (Engineering Management) , Abstract: This research project investigated and modelled Total Quality Management (TQM) for the Ghanaian construction industry. The primary aim of the research was to model the extent to which Leadership/Top Management features, Company Supplier Quality Management features, Client Focus and Involvement features, Company Quality System Evaluation features, Company Vision and Plan Statement features, Product Design Management features, Product Selection Management features, Construction Process Management and Improvement features, and Construction Employees’ Involvement and Motivation features predict TQM for the construction industry, these factors being classified as the exogenous variables. Mixed-methods research which involved both Qualitative and Quantitative approaches was adopted for the study. Empirical data was collected through a Delphi study and a field questionnaire survey. Analysis of results from the Delphi study was done with Microsoft Excel to output descriptive statistics. A conceptual integrated TQM for the Ghanaian construction industry model was based on the theory developed from literature review findings and the Delphi study. A questionnaire survey was conducted among the top management working in the construction industry in Ghana. From the 641 sample questionnaires, 536 questionnaires were returned which represents 83.62 per cent. An exploratory factor analysis (EFA) was conducted on the initial eight-factor constructs and their variables to determine their reliability for their inclusion in the confirmatory factor analysis (CFA). Nine-factor constructs were realized after the EFA factor loading test. Further, CFA was conducted on these nine-factor constructs using structural equation modelling (SEM) software with Eqations (EQS) version 6.2 software programme to validate and determine their reliability and inclusion in the final model. Findings from the literature on TQM studies revealed the theory that TQM implementations and practices and the latent variables lead to TQM in the construction industry. Findings from the Delphi study revealed that several factors (Leadership/Top Management features, Company Supplier Quality Management features, Client Focus and Involvement features, Company Quality System Evaluation features, Company Vision and Plan Statement features, Product Selection and Design Management features, Construction Process Management and Improvement features, and Construction Employees’ Involvement and Motivation features) were considered to be the most important determinants of TQM in the Ghanaian construction industry. Both findings revealed that TQM could be considered as an eight-factor model defined by the influence of TQM practices and experts in construction...

  • Description: Abstract: One of the foremost challenges faced by the construction industry is the issue of cost overruns. Cost overruns cut across construction projects of nations and continents as well. They vary in magnitude and occur irrespective of project size and location. Over the years numerous attempts have been made in the area of estimating cost of construction projects right and improving the efficacy or accuracy of cost estimating using different statistical methods. This research investigated the factors that contribute to cost overruns and developed a predicting cost-estimating model for public sector building projects. The aim primarily was to extract factors from historical data of completed projects and use these predictive factors to develop a predictive model. Two models were developed using the predictive variables from historical data by the use of multiple linear regression and extreme learning machine. These models were compared to see the accuracy of performance. Results from the study reveal findings that; predictive variables from historical data can be used to predict the cost of completion of construction projects at the contract award stage, the multiple linear regression model results as compared to extreme learning machine results shows that extreme learning machine performs better. The study brought to light the use of extreme learning machine for developing predicting cost-estimating models built on historical data from completed projects. This rarely exists in construction industry. It further substantiates the superior performance of extreme learning machine to multiple linear regressions using big data. The developed model can also be converted to desktop software for predicting completion cost by industry... , Ph.D. (Engineering Management)

  • Description: Abstract: Construction Projects are often delivered under a complex and uncertain environment, with claims and conflict being an inevitable part. It is vital to manage claims and conflict as soon as possible before they turn into disputes. The intent of this paper is to investigate the effects and cost of construction dispute in construction projects in Swaziland. The data used in this study were derived from both primary and secondary sources. The secondary data for the study was derived from the review of literature. The primary data was obtained through the use of a questionnaire which was distributed to client (government), contractors and consultant representatives (quantity surveyor, civil engineer, architects, project managers and mechanical and electrical engineers), only organizations registered with the ministry of public work and transport in Swaziland and other professional bodies were surveyed. Findings enacting from the survey revealed that the major effects of construction disputes in Swaziland construction projects were loss of productivity, loss of company reputation, loss of business viability, loss of profitability. With respect to cost of disputes, the findings revealed that hidden cost; indirect cost; direct cost, were major factor for cost of disputes. The results of this study contribute to the body of knowledge and provide valuable insight to actual effects and cost of disputes in Swaziland construction projects, hence the effects are ugly. The study recommends that every stakeholder in the Swaziland construction industry familiarise themselves with the strategies of avoiding construction dispute to avoid the occurrence. Also the government must take up an initiative of educating all stakeholders about dispute avoidance, it would save the project and company fortunes.

  • Description: Abstract: Lack of stringent measures in safety and construction laws has been attributed to poor performance in Health and Safety (H&S} in the construction industry. The purpose of the paper is to present how the conceptualized integrated H&S compliance model for contractors in Ghana will be developed. The conceptualized model theory forms the bases of the discussion in this paper. A total number of fifteen studies relevant to accident causation theories were selected out of the total number of thirty studies reviewed, through a rigorous process. The assessment of H&S compliance model for the study was carried out through the combination of objective and subjective attributes. The Domino Theory forms the basis for theoretical and conceptual framework of this paper. The study adopted various constructs from Accident Root Causes Tracing Model (ARCTM) and Domino theory. The hypothesized integrated holistic H&S compliance model is presented in this paper based on an in-depth review of the previous models. Government support and contractor's organizational culture serve as variable constructs identified as gaps in H&S compliance research. Discussions also included the integrated holistic model and the variables of the model, identification of the model and justification for the selected variables. The paper presented the conceptualized H&S compliance model. The gaps identified in H&S compliance research served as the variable constructs. They are government support and contractor's organizational culture.

Networking of domestic construction enterprises for infrastructural delivery : a strategy for construction industry development. International Conference on Infrastructure Development in Africa, ICIDA-2016
  • Description: Abstract: This paper argues that although infrastructure delivery results in numerous economic benefits, it can be a curse depending on who delivers it. This paper seeks to examine the impact of the influx of non-domestic construction companies and the possible effect of their activities on domestic construction enterprises, and the overall effect on the construction industry’s development agenda of Ghana. By design the paper is descriptive. The paper uses literature review as a method to identify, summarize and synthesize literature on infrastructure delivery and its impact on economic growth of nations, particularly Africa. The paper finds that major infrastructure projects are executed mostly by non-domestic construction firms largely due their greater experiences and resources which give them competitive advantage over their domestic counterparts. This situation is detrimental to the growth, survival and profitability of local construction consultants, contractors and individual practitioners and the construction industry development agenda of Ghana. The need exist for capacity building and / or improvement of domestic construction enterprises through networking to meet the challenges of globalization which are inevitable. The paper open new directions of infrastructural delivery research that focuses on the impact of the activities of non-domestic construction enterprises on the Ghanaian construction industry generally, the Ghanaian construction industry development agenda and the nations’ construction related social and economic development.

  • Description: Abstract: Effective and formal stakeholder management process is critical in achieving stakeholder needs and satisfaction, an important project success factor. Developed countries construction industries have embraced stakeholder management as a soft project management skill and consequently developed suitable approaches for improved project delivery though developing countries are yet. Studies have associated project failures to poor stakeholders' performance, the absence of formal stakeholder management process, industry challenges and lack of proper documentation in developing countries such as Ghana. This study identifies, reviews and documents the historical development of stakeholder management process in Ghana as part of a broader study aimed at "developing sustainable stakeholder management framework for construction process in developing countries" for enhanced project success. An exploratory method with the qualitative technique was adopted. A literature review was conducted into stakeholder management practice to explore the trend, influence of historical development and documentation of stakeholder management process in relation to industry challenges using three countries as case studies. This is aimed at documenting and developing sustainable stakeholder management process for developing countries. A descriptive survey was used for analysis and documentation. Findings are that formal documentation of industry practices, procurement challenges, stakeholders role in project failures led to the reviews and stakeholder focused reports which that advocated for collaboration. A trend which has influenced the development of stakeholder management process. In the absence of formal documentation, the study identified and documented stakeholder management historical development trend in Ghana for the development of a stakeholder management framework.

  • Description: Recent studies of the construction industry have revealed that project management has developed in the opposite direction over the past few years, towards a ‘harder’ and more stringent approach with an increasing degree of specialization. It has been observed that the present day construction activities require new management paradigms. Conversely, there are some new developments in the field such as Agile Project Management (APM). APM approach has gained momentum in other industries and is now being given consideration in the construction industry. Within this approach, the human aspect takes precedence over reliance on documentation. This research assessed the prospects of APM in the construction industry in Ghana using the SWOT analysis model. A mixed method approached (questionnaire and interview survey) was adopted to elicit data from respondents. Questionnaires were used to retrieve data from Construction Project Managers (CPM) whereas interview was conducted with some project management experts. The results of the survey revealed that there is a very low level of awareness of the concept of APM amongst CPMs in Ghana. Even though a small number of the respondents were aware of APM, they lack thorough knowledge of the concept as the concept has never been adopted in any of the projects managed by these professionals. However, majority of the CPMs welcomed the concept and were eager to know more about it. It is therefore recommended that more discussions, seminars, training, and workshops on APM and its importance should be initiated to enhance the level of awareness and knowledge in the Ghanaian construction industry. Likewise, further studies could also look at how both paradigms (APM and Traditional project management) can be mixed since they all have their weaknesses and strengths.
