Publication Authors Ibironke O. T., Adedokun, O. A and Hungbo, A. A.
Year Published 2011
Abstract

Motivation is the set of processes that determine the choices people make about their behaviours. Implementing a well formulated motivation policy triggers the innate qualities of labourers (employees) by enhancing their productivity. This study investigates the drivers of motivation for casual workers on the construction sites by
identifying the factors responsible for motivation and challenges to the motivation of casual workers in Nigerian construction industry. Relevant literature were reviewed and 18-point evaluation questionnaire was developed on the drivers of motivation while 11 were collated for the challenges of motivation for casual workers on construction site. The questionnaires were then distributed to the professionals and labourers within construction sites in Lagos state, Nigeria. The data collected were analysed using descriptive and inferential statistics. The study indicates that casual workers give in their best when there are provisions of reward for the good work and excellence, also when they are adequately provided with working equipmentsand facilities and that there is no significant difference in the perception of labourers and professionals on the drivers and challenges of motivation for casual workers on construction sites.

Abstract

One of the three most important basic needs of mankind which has not been adequate for the citizenry
right from the independence in 1960 till date is Housing. Finance has been fingered as one of the predicaments towards its actualization because housing provision requires huge capital outlay. The National Housing Fund (NHF) scheme was considered relative to the number of contributors, accessibility of the fund when required and how it has affected the provision of housing in Nigeria. Data for this work were obtained from the Federal Mortgage Bank of Nigeria (FMBN) which is the apex bank for mortgage institutions. The study revealed
that few mortgagors have benefitted from the scheme, funds are locked up without disbursing adequate amount to the contributors as there is wide gap between the amount that mortgagors actually applied for and the amount so approved for the provision of housing in Nigeria. The paper recommended that contributors should be allowed to benefit from NHF scheme, while funds locked up should be adequately disbursed to the loan applicants by ensuring that there is reduction in the wide margin between amount applied for and the amount so
approved to allow for effective utilization of the fund.

Publication Title Assessment Of Competitive Tendering Methods Of Procuring Educational Building Projects In Nigeria
Publication Authors O.A. Adedokun, O.T. Ibironke and S.O. Babatunde
Year Published 2013
Abstract

Purpose – This paper assessed educational building projects with a view to determining the level of utilization of competitive tendering methods, factors influencing their choice and predisposition to risk factors in order to
ensure effective construction project delivery.

Design/ methodology/approach – The paper assessed the level of utilization of competitive tendering methods, the factors influencing their choice and finally the predisposition of each of the methods to risk factors
adopting survey method which involved primary data, obtained by using multiple-choice questionnaire administered to the respondents (Architects, Quantity Surveyors, Builders, Structural Engineers, Civil Engineers, Mechanical & Electrical Engineers)

Findings – It was found that the usage of open competitive tendering methods outweighed selective tendering method of procurement as a result of accountability and price competition involved which made it predisposed to not only financial risk factors but also political and logistics factors.

Research limitations/implications – Multiple-choice questionnaire administered to the respondents (Architects, Quantity Surveyors, Builders, Structural Engineers, Civil Engineers, Mechanical & Electrical Engineers) was limited to the selected institutions in the southwestern zone of Nigeria.

Practical implications – The most widely adopted method (open competitive tendering method) suffers from risk factors like selective but high premium should be placed on financial and logistic risk factors in order to achieve hitch free construction project delivery. These measures will help the stakeholders in assessing degrees of project complexity and better manage the potential risks that might be induced to different levels of competitive tendering methods of project procurement in relation to educational building projects.

Originality/value – This empirical investigation provides strong evidence on the procurement of educational building projects in response to due process policy. The findings provided insightful perspectives to define and understand project complexity. For stakeholders, understanding and addressing the complexity help to improve
project planning and implementation.

Publication Title VULNERABILITY OF MOTIVATION SCHEMES IN ENHANCING SITE WORKERS PRODUCTIVITY FOR CONSTRUCTION INDUSTRY’S SUSTAINABILITY IN NIGERIA
Publication Authors Adedokun, O. A., Ibironke, O. T. and Olanipekun, A. O
Year Published 2013
Abstract

 The construction industry provides appreciable employment for the unskilled and semi-skilled labour considering the nature of most activities carried out on construction sites. However, the productivity of this categories of labour have trended poor overtime. This study therefore assessed the financial and non financial motivational schemes; in light of their preference to construction site workers so as to assure on their vulnerability in enhancing productivity. The data collected through the administration of questionnaires to construction site operatives were analysed using the relative importance index (RII). The research instrument was also legitimized with content validity index (CVI) for items 0.80 and cronbach alpha value, as a measure of internal consistency, 0.70. Allowances, wages stock option and bonuses are the financial motivators while delegation, independence and autonomy, facilities for transportation are the non financial motivations that are important to site workers on construction sites. Giving praises, encouragement to make contributions, free medical care, availability of relaxation centres and first aid provision are the motivation schemes that site operatives believed to enhance their productivity. This paper concludes that both financial and non financial motivational schemes are important to enhancing the productivity of operatives on construction sites. The vulnerable motivational schemes to the enhancement of productivity, as revealed in this study is recommended to the construction and subcontracting firms, foremen, clerk of works, site supervisors, site engineers and all other stakeholders in ensuring a maximum output for a unit input from site operatives.

Publication Title Evaluation Of Qualitative Risk Analysis Techniques In Selected Large Construction Companies In Nigeria
Publication Authors Adedokun, O.A., Ogunsemi, D.R., Aje, I.O., Awodele, O.A. and Dairo, D.O.
Year Published 2013
Abstract

Purpose
– This paper evaluated the adoption of qualitative risk analysis techniques (QRAT) on construction projects in Nigeria with the aim of providing better understanding on the state of these techniques.

Design/ methodology/approach – Questionnaire survey and in-depth interview were employed in gathering data for the study. The paper assessed the level of knowledge, awareness, utilization success and the factors affecting the utilization of qualitative risk analysis techniques. The primary data employed were obtained by using multiple-choice questionnaire administered to the selected large construction firms in Nigeria.

Findings
– The result of the study revealed a low level adoption of QRAT, thus preventing Nigerian construction industry from taking full advantage of QRAT in the analysis of risks inherent in construction projects. Also checklists, flowchart and assumption analysis were the commonly used QRAT in the study area. Furthermore, inadequate training and record keeping on risk management contributed largely to the factors affecting the utilization of QRAT on projects.

Research limitations/implications – Multiple-choice questionnaires administered to the respondents (Architects, Quantity Surveyors, Builders, Structural Engineers, Civil Engineers, Mechanical & Electrical Engineers) were limited to the selected large construction firms in the category D of the Nigerian Federal Tender Board.

Practical implications – The construction sector has not taken full advantage of QRAT in the analysis of risks inherent in construction projects. This has been responsible for cost and time overruns usually recorded. Analysing risks will help the stakeholders in assessing degrees of project complexity and better manage the potential risks that might be induced to different levels of construction projects in Nigeria in order to achieve
hitch free construction project delivery.

Originality/value – This empirical inquiry provides strong evidence on the state of qualitative risk analysis techniques of construction projects in Nigeria. The findings provide insightful perspectives to understand construction project QRAT in its entirety. For stakeholders, understanding and addressing the complexity help to improve project planning and implementation.
