Effects of workers motivation on construction productivity / Adebowale Oluseyi J. and Fapohunda Julius Ayodeji
No full textThe issue of construction workers motivation becomes a subject of debate among construction project management professionals. Therefore, there are diverse opinions on whether motivation of construction workers positively impacts construction workers performance or rather adversely
affects the general performance of construction labours. This brings about different motivation concepts and principle by researchers towards improvement of construction workforce performance. The paper takes into cognisance the perception of construction practitioners on motivation in relation with construction productivity towards achieving construction project objectives. In order to obtain a viable result of the study, the study adopts quantitative research approach on construction workforce
motivation with project managers, contract managers, site managers, contractors, and site supervisors. Quantitative data obtained was analysed with SPSS statistical tools. The perception of construction practitioners was explored on motivation drives of construction workforce. However, it was
found that motivation is important for construction workers performance, giving bonus to workers is important to improve workers efficiency and there is a need for construction workers recognition by management. The adequate application of recommendation of this study will enhance construction labour productivity, reduce wastes in construction, improve general construction performance and ultimately heightens customer's satisfaction
Critical evaluation of conscious and unconscious construction resources wastefulness towards achieving sustainable construction
No full textCurrently construction resources are not only scarce, but also increases in costthus, for the construction industry to become truly sustainable, the industry has to re-engineer towards lean principles where the requirement for effective resources waste management is considered paramount. Sustainable Construction follows directly from the necessity to satisfy the needs of construction industry stakeholders and the requirements of future generations. This paper identifies, evaluates and proposes an effective management framework that could support sustainable construction through efficient utilisation of construction resources and avoidance of conscious and unconscious resources wastefulness. Initial facts and insights were obtained through a detailed review of literature, augmented by primary data acquired by means of questionnaires and interviews with construction practitioners. The data collected were analysed using SPSS and NVivo statistical packages. These data and information are collected within the UK construction industry. Findings from the research highlight that, majority of these resource wastes termed unavoidable are avoidable. In respect of these, minimisation of conscious and unconscious resources wastefulness and efficient utilisation of resources are absolutely essential towards enhancement of sustainable construction. The proposal outlined in this paper will significantly enhance the efficient utilisation of construction resources and perpetuate sustainable construction, if properly implemented

Causes and effects of cost underestimation on construction projects in South Africa
No full textThesis (MTech (Construction Management))--Cape Peninsula University of Technology, 2017.The South African construction industry is faced with challenges which contribute to unsuccessful project delivery. Cost underestimation have negative contribution to construction projects, the effects and causes of cost underestimation have not been adequately explored with the objective of providing mitigating mechanisms. This study is aimed at investigating factors which contribute to cost underestimation, the prevalence of cost underestimation in relation to causes and effects of cost underestimation, with the final objective to establish mechanisms for efficient mitigation of cost underestimation.
The study review literatures relating to cost estimation, and additional data were collected in form of a structured questionnaire. The questions highlight the following areas; project planning, method and techniques, and tools as factors contributing to cost underestimation; scope changes and risk associated with specialized building works as prevalence of cost underestimation; planning stage, design and material changes risk due to unforeseen factors as causes of cost underestimation; loss of reputation, exposure to risk and financial loss as effects of cost underestimation; and design requirements, effective techniques and planning as cost underestimation mitigation mechanism.
A total of one hundred and forty two (142) emails were sent via the survey website to the selected respondents and seventy four (74) responses were received. A quantitative approach was used and a convenient purposive sampling of respondents was used by handpicking the respondents from the available register of the South African Council for Quantity Surveying Professions (SACQSP) and the general building contractors registered with Construction Industry Development Board (CIBD), construction professionals working in quantity surveying practice and construction firms within and around Cape Town
Framework to enhance engineering undergraduates entrepreneurial education towards sustainability of employment in South Africa
No full textThesis (Master of Construction (Construction Management))--Cape Peninsula University of Technology, 2019The study investigates the factors relevant to the enhancement of engineering undergraduates’ entrepreneurial education aimed at sustainability of employment in South Africa. The research utilised a mixed methodological approach, at it involves the use of semi-structured qualitative interviews and closed-ended quantitative questionnaires, both of which were administered to engineering students (chemical engineering, civil engineering, construction management and quantity surveying, electrical, electronic and computer engineering, industrial and system engineering and mechanical engineering) in two selected universities in the Western Cape Province of South Africa. The quantitative data generated from the questionnaires was analysed using SPSS Version 25 software, while the ‘content analysis’ method was used to analyse the information generated through the qualitative interviews.
Based on the findings obtained in this study, various significant factors that can enhance entrepreneurial interest of undergraduate students are grouped: as perceptions, attitudes, knowledge, personality traits, education and training, entrepreneur’s innovativeness, access to business information services, access to finance, technology, and government policy. However, lack of appropriate technical and life skills, among other factors, contributes to poor ability of graduates to establish their own businesses after graduation. Predictably, findings also indicate that innovativeness enhances entrepreneurship positively. There is a need for an emphasis on innovativeness in educational syllabi in HE schooling. Additionally, access to business information services is an area that requires more attention from the government, since higher education graduates in South Africa are often handicapped by a lack of adequate business support services and poor information technology infrastructure. Lack of access to credit is another common problem for graduates trying to start their own businesses.
In addition, findings revealed that the majority of students had significant entrepreneurial interest and attributes, wanting to start their own business within one year of graduation. The majority of respondents indicated that the course delivery should be practical and be learnt through business activities or application of practical cases instead of learning about business in a strictly theoretical fashion. Furthermore, to strengthen the delivery of the curriculum, it is recommended that the content, teaching approaches, assessment, etc., be better adjusted to the original interest of entrepreneurship education. A tracing system is recommended in order to follow students’ progress over three successive years from their graduation
Evaluation of site managers’ hindrances towards optimal utilisation of construction resources
No full textPurpose – The purpose of this paper is to delineate different types of site manager attributes that
significantly contribute to construction project management efficiency and evaluate the factors that
hinder the site manager during construction production processes. Towards efficient resources
utilisation, site managers require various qualities and potentials.
Design/methodology/approach – To achieve valid result, the research study was triangulated by
exploring literature, which was augmented with both quantitative questionnaire and qualitative
interview research methods. The research data were collected in the UK building industry.
Findings – It was found that the barriers that often affect efficient utilisation of construction resources in
the industry are poor communication, disagreement, misunderstandings, bad weather, union strikes and
construction participants’ personality conflicts. This research study presents severity of site manager’s
hindrances, factors that affect site manager’s efficiencies, solutions to minimise the hindrances on site
manager’s efficient performance and factors that should be constant towards site mangers’ efficient
performance. Among these solutions found evident that will enhance site managers’ performance and
minimise the effect of the hindrances are an enhanced planning and adequate programming of construction
resources before and during project execution, rational team building and an efficient construction team for
project, in addition to adequate information dissemination and transfer of knowledge.
Originality/value – The adequate implementation of the solutions presented in this paper will not only
enhance the performance of site managers on resources utilisation but will also augment client satisfactions
Operational framework for optimal utilisation of construction resources during the production process.
No full textThe construction industry contributes a significant amount to a nation's Gross Domestic Product and National Income. The industry products are enormously important to other organisational sectors, and provide a considerable amount of employment to the nation's populace. However, the industry is significantly under-achieving in terms of clients' and stakeholders' satisfaction. In addition, the resources in the industry are currently under-utilised. It is affirmed that resources' wastes management in the industry is far behind that obtainable in other organisational sectors. Thus, there is a need for re-assessment of the way in which the industry generates its products towards utilising the scarce and costly resources efficiently.It is noteworthy that a project could be completed, within the estimated cost, time frame and quality expected, and even satisfying the clients' and stakeholders' implied needs, with lots of resource wastefulness during the construction production process. Despite the lean construction techniques being effective in reducing resources utilisation wastefulness; currently there are difficulties in achieving the approach objectives adequately. Thus, to maximise resources utilisation and avoiding inefficiency, it is paramount to critically evaluate, identify, and establish the several wastage occurrences, occurring either consciously or unconsciously during the project construction process.This research responded to the need for the construction industry to review the use of resources during production process, and to minimise the "gap" between the construction industry and the other sectors in efficient resources utilisation.To establish a valid and reliable best practice operational framework, towards utilising construction resources optimally, this research study was triangulated. Both structured and unstructured questionnaires and in-depth interview research surveys were exploited for its data collection. The Statistical Package for the Social Sciences version 13, (SPSS 13), software was used to analyse the data obtained through the questionnaire research survey, while NVivo, (version 8) statistics software was explored to analyse the information collected through the in-depth interview research survey.This research was grouped into three main studies. The first study evaluated the issues associated with site managers' efficient performance, and causes of site managers' inefficiency in performances established were identified. In this respect, the factors that will enhance site managers to optimally utilise resources were established. Secondly, the scenarios of budgeting for resources' wastes were investigated, and factors that will reduce their effects on optimal resources utilisation were established. Lastly, the causes and modalities of averting resources wastefulness during the production process were investigated and ascertained. The success factor of these studies is the evaluation of the knowledge, attitudes, and perceptions, (KAP), of construction participants on resources utilisation. Based on these three main research studies and their sub studies, an operational framework for optimal utilisation of construction resources during the production process was developed, validated and established.This research study was conducted within the UK construction Industry. The implementation of the research findings and inferences will not only enhance optimal resources utilisation in the UK construction industry. In respect that the UK construction industry is vast in innovations, research development and construction reengineering, the established framework is significant for global construction industry adoption
Achieving optimal resources utilisation through efficient integration of project management systems and techniques: An overview
No full textManagement of a project is the responsibility of all construction project personnel working within the project province; striving for the succession and successful achievement of the project objective(s). The construction project managers strive to maintain the progress and mutual interaction of various parties involved in project initiation and execution to ensure that the risk of failure is reduced. Thus, maximisation of resources utilisation during the construction process could only be achieved through effective implementation of various management techniques. Thus, this study evaluates different project management systems and techniques and presents models towards achieving optimal resources utilisation through efficient integration of these management techniques
