    A Comparative Analysis of Methods of Procuring Plant and Equipment in execution of Construction Projects
    (Journal of Environment and Earth Science, 2015) Alumbugu, Polycarp Olaku , Saidu, Ibrahim, Wasiu Adeniran Ola-awo, Abdulmumin Abdulazeez Adedeji Nike Shakira
    Contractors encounter a lot of problems in decision making on how to acquire plant and equipment to execute project to attain cost effectiveness to either purchase or to hire. The paper examined the relationship between procurement method preference and some selected variables (value of contract, contract size, contract type and contract period) A total of 75 questionnaires were administered to different indigenous construction companies in Abuja using the random sampling method. The data were analysed using simple spearman correlation, simple percentage and Relative importance index. It was concluded that it is more economical to hire plants that are not frequently put to use (specialized plants). High cost of equipment was the major reason contractors preferred to hire than purchase plant. It was recommended that government should make efforts to reduce hire rate and a national Centre for manufacturing of construction equipment be established partnering with stakeholders in the construction industry.

    Assessment of the Factors Affecting Accuracy of Pre-tender Cost Estimate in Kaduna State, Nigeria
    (Journal of Environmental Science, Toxicology and Food Technology (IOSR-JESTFT), 2014-05) Alumbugu, Polycarp Olaku , Wasiu Adeniran Ola-awo Saidu, Ibrahim Abdullahi, Mustapha Muhammed & Abdulmumin Abdulazeez
    Accurate cost estimates are crucial to the effective realisation of construction projects. Researchers have noticed the presence of inherent inaccuracies in the bill of quantities prepared by estimators (Quantity surveyors). This paper aimed at examining the factors affecting accuracy of pre-tender cost estimate in Kaduna state, with a view to improving the predictive ability of clients, consultants, and contractors for better estimating. A total of 66 questionnaires were administered with 35 to consultants (53.03%), 15 to contractors (22.73%) and 16 (24.24%) to clients within Kaduna using the simple random sampling technique. The collected data were analysed using the Relative Importance Index and correlation analysis. The study found out that a statistically significant relationship existed between the clients, consultants, and contractor on the essential factors affecting accuracy of pre-tender cost estimate. It was concluded that: Experience and skill level of the consultants, Project teams experience on the construction type, clear and detail drawings and specification, completeness of cost information, accuracy and reliability of cost information are the most significant factors affecting accuracy of pre-tender cost estimate. It was recommended that Clients should always engage the services of skilled professionals to undertake the consultancy services in cost estimating process.

    Demystifying the Effects of Final Accounts Settlement on Building Contractors in Abuja, Nigeria
    (Environmental Technology & Science Journal, 2018-06) Johson Abidoye, Saidu Ibrahim, Adamu A.D. and Alumbugu Polycarp Olaku
    The final account stage of a building project is sometimes rarely settled or even being delayed by some of the project parties, thereby posing serious challenges on contractors. This research examines the effects of non-settled final accounts on contractors with a view to suggesting the best strategies for settlement of final accounts in building projects. A quantitative technique was adopted in this study. The research population constituted the major construction participants consisting of public clients, registered consultants and contractors within Abuja. The stratified random sampling method was adopted. A total of 162 structured questionnaires were administered to the participants from whom a total 119 was retrieved representing 86% response rate. The collected data were analysed using the descriptive methods and Analysis of variance. The research found that the major barriers of procurement methods that must be considered if final accounts are to be settled are: inadequate documentation of records, ambiguity of final account settlement procedure, and silence of contract conditions on final account settlement. Also, unsettled final account will have significant effects on contractors especially in the aspect of cash flow, threat to life of the contractor’s business, financial hardship for the contractor, and contractor’s insolvency. It was also found that the problems could be mitigated through maintaining separate escrow bank account by the client, legal and contractual provision. Based on these findings, it can be concluded that proper management of the identified factors would translate into effective settlement of final accounts in building projects. The research recommends that construction clients and consultants should employ care when selecting a procurement option to be used.

    Assessment of the Cost Impacts of Health and Safety Practices on Construction Projects in Abuja, Nigeria
    (Environmental Technology & Science Journal, 2018-06) Sanni Otaru, Saidu Ibrahim, Yakubu D. Mohammed & Alumbugu, Polycarp Olaku
    Forecasting the costs of a construction project usually fails to include the cost of health and safety of the construction workers, and the construction process itself contains a series of crafty activities which require time and costs for smooth execution. Thus, the research aimed at assessing the cost impact of health and safety practices on construction projects. The study adopted quantitative technique. The research population constituted the professionals in the construction industry who are directly involved on construction sites.A total of 181 structured questionnaires were administered to the sampled participants (23 project managers, 43 consultants, 48 contractors and 67 safety officer) within Abuja, using the stratified random sampling method, from which a total 170 was retrieved, representing 93.9% response rate. The collected data were analysed by using the descriptive methods (Relative Importance Index, frequencies, percentages and ranking method). The research found that struck by falling objects; slip, trip and falling from heights; collapse of cranes; death; and respiratory deformation, are the major health and safety risks that have major effects on project cost. The research also found that the provision of health and safety programs on construction sites contributes between 3–5% of the project costs. It was also revealed that the percentage cost of accidents to the overall cost of construction projects is less than 1%, with an average percentage contribution of 0.218%.Based on these findings, it can be concluded that the costs of health and safety programs and practices are significant in increasing the costs of building projects.It was recommended that health and safety practices and programs should always be given priority at the initial project estimating stage of a project, as they constitute a reasonable percentage of project cost.

    Nexus of Economic Recession and Building Construction Cost in Nigeria
    (The Quantity Surveyor, 2019-10) Oludolapo Ibrahim Olanrewaju Luqman Oyekunle Oyewobi, John Ebhohimen Idiake Alumbugu, Polycarp Olaku, Sunday Ajiboye Babarinde & Ayodeji Emmanuel Oke'
    Economic recession became pronounced in the year 2008 to 2009 when the annual growth rate of Nigeria dropped from over 9% to 6.7% leaving macroeconomic variables such as GDP growth rate, oil price, exchange rate, unemployment and underemployment, inflation and external reserve relatively unstable. This study is aimed at examining the nexus of economic recession and building construction cost in Nigeria. Secondary data were obtained from journals, Central Bank of Nigeria (CBN), National Bureau of Statistics (NBS) and archival data on prices of building materials from building materials merchants. The data were analyzed using inferential statistics and it was revealed that the indicators of economic recession (inflation rate, prime exchange rate, prime lending rate, gross domestic product (GDP), price of building construction materials and crude oil have strong influence on building construction cost in Nigeria. It was thus concluded that economic recession was not anticipated by the Nigerian government and as such relevant strategies to neutralize the effect of the economic recession that can stabilize construction materials prices and macro economic variables was not in place. It was therefore, recommended that; petrol pump price and crude oil should be regulated to prevent its resultant effects on construction cost and that viable fiscal policies should be instituted by government to prevent future occurrence of recession.

    (Journal of Engineering, Project, and Production Management, 2019-10-13) Alumbugu Polycarp Olaku , Winston W. M. Shakantu , & Abel John Tsado
    Outbound logistics channels are of crucial importance for an efficient construction materials logistics management and impacts on customer satisfaction. However, there is limited knowledge of the outbound logistics channels for construction material in Nigeria. This study aims to identify and examine the current outbound logistics channels used by the Nigerian construction material manufacturing industries. A quantitative research method using a case study approach was adopted in this research. The purposive sampling technique was chosen, where six construction material manufactured and distributed within five states capital and Abuja in the North-central region of Nigeria were selected for this study. A research instrument was developed and used in conjunction with an observation protocol in the form of a template. The data were collected through observations, direct measurement onsite and archival records of transactions. A descriptive method of data analysis was employed to analyse the data. Our findings indicate that there exist six alternative outbound logistics channels that can be used separately or in combination with each other to deliver materials to end users. The study concludes that the research finding provides a potential knowledge and understanding of the manufacturers’ outbound logistics channels that can be used at the start of a project to accomplish effective planning and delivery of the whole project. The study also established the average transportation cost per average ton and average transportation cost per average distance driven for construction material delivery. This information can be used for construction material transportation management

    Contract Awards Disparity among Multinational and Indigenous Construction Companies
    (Journal of Engineering, Project, and Production Management, 2019-06-19) Tsado Abel John , Alumbugu Polycarp Olaku , & Archibong Imoh Micheal
    The key players in the construction industry are the construction companies. However, the level of contract awards among multinational and indigenous construction companies in most developing countries is poorly understood. This research aim at determining the level of contract awards among multinational and indigenous construction companies. The research employed a quantitative approach using both primary and secondary method of data collection to achieve the stated objective. Purposive sample techniques were used for collecting both the primary and secondary data. Structured questionnaires were administered to 70 construction professionals and contractors to determine the factors responsible for low indigenous contractor’s participation and award of contracts. Primary and secondary data were collected, and the findings reveal that 65% of the contract awards between 2002 and 2012 were won by the multinational construction companies. While the lack of requisite skill and technical know-how with a percentage severity index (SI) score of 97% was responsible for low indigenous construction companies awards. This result indicates that the multinational construction companies are dominating the construction industry.

    Factors Responsible for Slow Adoption of Partnering on Construction Projects in Nigeria
    (INTERNATIONAL JOURNAL OF BUILT ENVIRONMENT AND SUSTAINABILITY, 2018-01-30) Adeniran Wasiu Ola-awo, Roslan Bin Amirudin, Alumbugu Polycarp Olaku & Mukaila El-Hussain Abdulrahman
    Partnering procurement method attracted general acceptance due to potential benefits attached globally. Partnering arrangement was embraced in Nigeria, but the level of implementation is low, the stakeholders hold on to the traditional procurement in spite of its harbored problems. A study that investigated the factors responsible for the slow adoption of partnering in construction in Nigeria is rare. This paper examined factors responsible for the slow adoption of partnering in construction projects execution in Nigeria. This study was conducted using quantitative approach via selfadministered questionnaires on construction practitioners (clients, contractors, and consultants) that have handled partnering projects before. The analysis was conducted using descriptive statistic, Kruskal-Walis, and factor analysis. The analysis reveals that there is an agreement in the ranking of twenty-five out of the twenty-nine factors identified. The study discovered that attitudinal and behaviors factor; lack of technical know-how; external, economic, and institutional related factor, procurement related factor, ineffective communication; unethical related issues, and lack of commitment are responsible for low level of implementation of partnering in Nigeria. The study findings would assist the practitioners and decision makers on how to achieve best results from their partnering projects. It would also lead to performance improvement which would subsequently lead to the reaping of benefits. The understanding of these factors would assist the decision maker to plan to tackle it

    The analysed the relationship between working height and productivity of masonry worker on construction site by investigating two project sites. Data were also gathered by observing work activity on site. Time study form was design to record the various elements of the task performed and the time taken to complete each element over a period of observation at both floor levels for a period of six working days. A total of thirty structured questionnaires were administered on the factors affecting workers productivity on construction site. T-test was used to determine the difference between productivity at different level. The research concluded that the factors affecting\workers productivity are: Availability of materials, Weather, Gang size, Enabling environment, Height of work have strongly significant effect on the productivity of workers output on construction sites. A none statistically significant difference existed between the output of block laying at both floor levels but a statistically significant difference existed between the output of concrete work at first suspended floor slab and second suspended floor slab. It was also concluded that the output determined for Block laying was 12m2 /day, Concrete work 19m2 /day and16m2 /day at 1st suspended and 2nd suspended floors respectively. It was recommended that the result of this research should be used to provide information upon which planning, scheduling and cost control of block laying, plastering and concrete works can be carried out.
