    ECONOMIC IMPACT OF ELIGIBILITY DOCUMENTS COSTS ON BIDDING PUBLIC SECTOR PROJECTS IN NIGERIA
    (POLAC MANAGEMENT REVIEW (PMR), 2021-10) Yahaya, M. L.; Babalola, A. J.; Sani, M.
    This study aimed at forecasting the economic value of those eligibility document (ED) toward government revenues for a proceeding year. ED is the mandatory requirements need to be presented by any contractors or supplier to show his eligibility and capability for the project. A quantitative survey research methodology was adopted, with structured questionnaires administered to contractors in North-West Nigeria. Times series and regression analysis were employed in the analysis of the data collected. The contribution of the construction sector towards the growth of the country’s economy over the years has been affecting government revenue generation. These could be as a result of poor performance of the construction industry in the implementation of infrastructural projects among others. Thus, results show a significant contribution of approximately ₦5.2billion by the sector through those ED. The study concluded that the sector contributes towards the economic growth of the Nigerian GDP, but more is required by addressing the associated challenges that surrounded the sector as well as the business environment, such as conducive business environment, taxes holiday and more development projects initiated from the government in it budget appropriation. The study recommends easy access of actors in the Building and Construction sector to credit facility with less interest rate.

    IMPACT OF INFLATION TARGETING IN SOUTH AFRICA ON PRIVATE SECTOR SPENDING ON CONSTRUCTION
    (JClRE, Journal of Department of Estate Management, University of Lagos, Nigeria .., 2016) Babalola, A. J.
    The purpose of this study is to investigate the effects of inflation targeting on the private sector spending on construction in South Africa. The research approach was quantitative and the data were historical, drawn from different data sources such as South African Reserve Bank, Statistic South Africa and Quantec. The data used were private sector spending on construction as the dependent variable while GDP, inflation rate and interest rate were independent variables covering the period between 1984 and 2011. The estimation technique used is the ordinary least squared method. To ensure that the model is robust and alid, diagnostic check such as R-squared; probability ofF-statistics; and normality were carried out. It as discovered that the model is robust, stable and all the independent variables jointly influenced the pendent variable. The study recommended that the monetary policy in South Africa should look into ays of growing the economy so as to make itsustainable, thereby promoting every sector.

    Influence of Macroeconomic Variables on Cost of Road Infrastruture Development in Nigeria: The Case of Lagos State
    (, Journal of Contemporary Urbanology, Department of Urban and Regional Planning, Benue State University, PMB 102119, Makurdi, 970001, BNS, Nigeria or P.O.Box 735, Makurdi., 2019-08) Babalola, A. J.; Oni, S. O.
    Nigeria is deficient in the area of infrastructure development and this is seriously affecting the growth and' sustainable development of the country. This study assessed the influence of macroeconomic variables on the cost of road infrastructure development in Nigeria. The Ex-post facto survey research or causal-comparative research design was adopted. The data on the macroeconomic variables used in the study, including inflation rate, interest rate, exchange rate and Foreign Direct Investment (FDI}inflows in construction sector were obtained from the National Bureau of Statistics (NBS) and Central Bank of Nigeria (CBN), the cost of road infrastructure development for the years under review were obtained from the Ministry of Works Housing and Infrastructure Development, Lagos State while the rates used in the buildup of the cost of the materials were from Guardian's monthly review of building materials prices which has taken care of all states of the country. The study fo that the trends of both the dependent variable and the independent variables were unstable, therefore affecting the nature of the macroeconomic environment prevailing in Nigeria and then causing the slow economic growth of the country. The study also found that there is relationship between the inflation rate, interest rate, exchange rate, FDI inflows in construction sector and the cost of road infrastructure development in Nigeria. The study recommends that the government should embark on policies that will make the Macroeconomic environment to be stable so as to increase the pace of the economic growth, reduce thefrequentfluctuation of construction materials prices and also increasing the development of infrastructures in the country.

    LINKING CLIENTS, CONTRACTORS, PROJECT MANAGEMENT AND TRANSACTION COSTS MAGNITUDE IN CONSTRUCTION PROCUREMENT IN NIGERIA
    (The Lagos Journal of Environmental Studies, 2019) Yahaya, M. L.; Onukwube, H.N.; Babalola, A. J.
    Project stakeholdersand management efficiency have been regarded as the main variables responsible for high transaction costs in construction project procurement in Nigeria. Additionally, investigations of their effects on transaction costs are relatively few in North-Western, Nigeria. This paper attempts to determine the impact of clients, contractors’ attitudes and the effectiveness of project management on the magnitude of transaction costs (TC) and to determine the significance of such impacts on TC. In order to achieve the objectives, a field survey involving a sample size of 100 procurement expert participants drawn from contracting public and private for procurement of works, services, and goods were employed, using structured questionnaires. Partial least square structural equation modeling (PLS-SEM) was used in analysing the information gathered. The research shows that both client and contractor unethical attitudes towards building procurement influence the transaction costs of each party. Similarly, the effectiveness of project management was useful, but not significant for the TCs. The research concludes that parts of the responsibility of the owners in the transaction are to strengthen mutual knowledge, collaboration and amicable dispute resolution, and mutual relationship with other procurement stakeholders.

    Macroeconomic Variables and Foreign Direct Investment (FDI) Inflows in the Nigerian Construction Sector
    (JOURNAL OF CONSTRUCTION INNOVATION AND COST MANAGEMENT (JCICM), DEPARTMENT OF QUANTITY SURVEYING, UNIVERSITY OF LAGOS, NIGERIA, 2020) Babalola, A. J.; Fayomi, M. A.
    The inconsistence of the macroeconomic variables performance and the low gross domestic savings can attributed to the low infrastructure development in Nigeria. Toreduce the problem of poor infrastructure development in Nigeria, capital must be mobilized from the high income countries to increase the preser: low gross domestic savings. The aim of this study is to investigate the influence of macroeconom; variables on FDI inflows in the Nigerian construction sector. The methodology adopted for this stud. was an ex-post facto survey research because it was based on existing or secondary data. Annual time series data of the FDI inflows in the Nigerian construction sector, Foreign exchange rates, inflation rates; and interest rates were used. Archive materials from Central Bank of Nigeria (CBN)and National Bureau of Statistics (NBS), annual data from 1990 to 2016 were used for analysis. The variables for this stud. were tested for stationarity. The unit root test results revealed that the variables were non-stationary - levels but they attained stationarity at first difference. The regression analysis of Ordinary Least Squ (OLS)method was used to analyse the data. The result revealed that exchange rate has positive impac:: but not significant. The result also indicated that interest rate and inflation rate have negative impact FDI inflows but not significant respectively. Johansen Co- integrated test conducted revealed that th existed a long-run relationship among the variables in the study. The study also established from [ohansen Co-integrated test that FDI and construction sector is significantly eo- integrated, indicatin a valid relationship at 5%. The result from the OLS model indicated that causality that exists between FD and the construction sector is bi-directional. Hence construction sector influence FDI inflows as well FDI inflows influence construction sector in Nigeria. The causality between FDI and the constructi sector should encourage policy decisions that will improve the FDI inflows, which by extension wou, translate to boosting the construction industry's opportunity to meet infrastructure deficit.

    Model of Predicting Bidding Costs for Construction Projects in Nigeria using Public Procurement Act 2007
    (International Journal of Engineering Research & Technology (IJERT), 2020) Yahaya, M. L.; Umar, I.; Babalola, A. J.; Sani, M.
    The costs incurred by various stakeholders participating in the tendering process and their magnitude has attributed incongruity between government and contractors, economic drain and less competition in public sector projects. The aim of the study is to develop model that predict the transaction cost of bidding construction projects based on Public Procurement Act 2007 (PPA 2007). To achieve this, quantitative survey design based on structured questionnaire was used. The data collected from 143 sampled contractors selected using stratified sampling techniques from the North-West states of Nigeria were analyzed using Partial Least Squares-Structural Equation Modeling software. The results from the analysis revealed three (3) major sources of transaction costs identified from the field as; eligibility documents, contract administration costs, and securing related documents methods. In addition, the three identified transaction costs sources were found to be significant determinants of transaction costs for contractors bidding for construction projects of various types. Moreover, bidding costs model was found to exhibit good forecasting power that can be used to predict the magnitude of costs incurred by contractors in bidding projects in Nigeria. The study concludes that the transaction costs of contractors in bidding construction projects on average is 8.21% of contract sum after validating the model with real life data, and it will benefit incoming firms into the industry as a bidder by knowing their entry probable costs indicators for public projects. The study recommends that further studies should be explore to identify some potential factors such as Equipments, financial capability and professional staff strength which could provide new insights into bidding transaction costs incurred for construction projects.

    Perception of the Nigerian Quantity Surveyors on the Panorama of Disputes in the Nigerian Construction Industry
    (International Journal of Environmental Studies and Safety Research, 2018-03) Ojo, S. M.; Babalola, A. J.
    Persistent disputes among contracting parties in the Nigerian construction industry is a cord in the wheel of effective construction projects delivery. The aim of this study is to evaluate the causes of disputes among the contacting parties in the Nigerian construction industry and to proffer solutions or strategies on how to minimize or resolve them. This study mirrors the perception of The Nigerian Quantity Surveyors (NQSs) as to causes of construction disputes. Stratified random sampling technique was adopted with the use of structured questionnaire for data collection. Eighty (80) questionnaires were distributed and Fifty five (55) professionally qualified Quantity Surveyors in consulting, contracting, educational and public service sectors filled the questionnaire. The study shows that client’s outright refusal to pay for or late payments of work done by contractor and variations order, sub-standard works on the part of contractors and design inadequacies on the part of the consultants are the dominants causes of construction disputes in the Nigerian construction industry. The study concluded that disputes in the Nigerian construction industry can be minimized or avoided if all the stakeholders are always ready to perform their duties as stipulated in the conditions of contract. The study recommends that clients should be financially buoyant before embarking on any construction project in other to pay contractors’ promptly as stipulated in the conditions of contract. Thorough review of the designs will minimize or eliminate variation. To avoid shoddy work, previously completed jobs as claimed by the prospective contractor should be visited to ascertain contractor’s technical capability. To ensure accurate design that meets the client’s need and devoid of inadequacies, design model and briefing section should be a predominant duty of design team to help clients have a better idea of the end product and iron out grey areas before construction phase.

    Perceptions of Construction Students on Industrial Training in Nigeria
    (2017-10) Babalola, A. J.; Obianeri, R.
    ABSTRACT Purpose: This study evaluates the perceptions of construction students on industrial training in Nigeria, with a view to suggesting ways of improving the Student Industrial Working Experience Scheme (SIWES). Design/methodology/approach: The study is a descriptive survey research in which 100 copies of a structured questionnaire, based on the objectives of the study, were administered to assess the perceptions of construction students. The questionnaire was fully responded to. Findings: The study found: that the students benefited from their SIWES programme and were exposed to real working environments in their area of studies; that there were improvements in their personal, working and communication skills; that they gained knowledge of the latest technologies as well as other knowledge that would be useful in their working lives. Practical implications: The study encourages students to participate actively in the SIWES programme and pay serious attention to their industrial supervisors. However, employers should do more to equip students technologically, while the government should adequately fund and monitor the programme in order to meet its objectives. Originality/value: The study examined the present state of the SIWES programme in Nigerian universities and advocates its improvement towards enhancing economic development. Keywords: Construction industry; Construction students; Nigeria; SIWES: Training
