    Safety Management Practices Adopted in Building Construction Sites in Niger State, Nigeria
    (Benue State University Journal of Education (BSUJE), 2019) Aisha, A. M.; Igwe, C. O.; Okwori, R. O.
    The study was designed to determine the utilization of safety facilities in building construction sites in Federal Capital territory Abuja and Niger State, Nigeria. Two research questions and two null hypotheses guided the study. A descriptive survey research design was adopted for the study. The study was conducted in FCT Abuja and Niger State, Nigeria. A total of 181 respondents consisting of 20 contractors, 71 builders and 90 tradesmen with 43 items structured questionnaire were used. The internal consistency of the questionnaire was determined using Cronbach alpha method and coefficients of A ꞊ 0.889 & B ꞊ 0.727 respectively. Weighted mean and standard deviation were used to analyze the research questions while ANOVA was used to test the null hypotheses at 0.05 level of significance. The findings of the study revealed that the respondents agreed with that of the safety facilities were utilized by the construction site worker while some were not complied. This implies that, safety facilities needs to be utilized in building construction. The findings revealed that there was significant difference in the mean ratings of the responses of the three groups of respondents (20 contractors, 71 builders and 90 tradesmen) as regard the of safety facilities. Similarly, there was no significant difference in the man ratings of the respondents as regards the extents of utilizing safety facilities in building construction sites. It was therefore recommended among others that contractors, builders and tradesmen require appropriate training/induction regularly on the use of safety facilities in building construction site base on their peculiarities. There should be appropriate information concerning the use personal protective equipment (PPE) at work to prevent accident from site. Working environment should always be cleared and kept free from all objects that can cause harm or injure the workers in building construction site.

    Application of lean manufacturing tools and techniques for waste reduction in Nigerian bricks production process
    (In Engineering, Construction and Architectural Management Journal @ Emerald Publishing Limited, 2019) Aka, A.; Isah, A. D.; Eze, C. J.; Timileyin, O.
    Purpose – Non-value adding activities or wastes in the lean term have been the major challenge of the construction industry. Numerous studies have been conducted to investigate how such wastes can be reduced so as to improve the performance of the construction industry. However, the aspect of bricks production process (BPP) has not been extensively covered. Therefore, the purpose of this paper is to investigate the application of lean manufacturing concepts in BPP with a view to identifying the various wastes in the practice, the causes of these wastes and how such wastes can be reduced. Design/methodology/approach – Mixed methods research design was adopted by the researchers where literature review was first conducted to establish the fundamental theories and practice standards of lean manufacturing process. Thereafter, a phenomenological study was carried out in a Shelter Clay and Brick Factory located in Minna, Niger State, Nigeria. The data obtained in the phenomenological study were analyzed through content analysis. These data served as the basis for the validation survey that subsequently followed the phenomenological study. Findings – The findings in the study show that poor or inadequate supervision is the main factor responsible for wastes such as excessive drying of bricks, overheating of bricks and re-glazing of bricks in Nigerian BPP. Research limitations/implications – The study focused on the various wastes in Nigerian BPP. It also focused on the various lean tools/techniques that can be adopted to reduce the wastes. Aspects such as the percentage of the wastes and their cost implication on the factory were not covered during the study and could be further investigated by prospective researchers. Practical implications – The study provides knowledge on how lean thinking can be adopted to reduce wastes in BPP. Such knowledge may be beneficial to the present and prospective bricks producers. This implies that the proposed framework in the study allows producers of bricks to identify gaps in their implementation efforts, focus attention on areas that may require improvements, and access the benefits of lean approach in their factory products. The proposed framework may also be beneficial to the academics. Originality/value – This paper first gain originality in the study context to propose for a lean framework that can be adopted to reduce wastes in BPP. Furthermore, the paper has not been previously published and all the information obtained from other sources are duly referenced.

    Equipment Acquisition and Maintenance Capability of Construction Firms in Abuja, Nigeria
    (ATBU Journal of Environmental Technology, 2024-06-01) Olubajo Oluseun Olukemi
    Research into construction equipment tends to focus on output and criteria for selection. However, investigations that examine the capability of construction firms to acquire and maintain equipment are limited. This study examines the capability of construction firms to acquire and maintain equipment in Abuja, Nigeria. A survey approach was adopted, and data was obtained through self-administered questionnaires to 45 construction practitioners from 45 construction firms purposively sampled in the Federal Capital Territory Abuja, Nigeria. The study used descriptive statistics to analyze the capabilities of firms, and the results showed that the method of acquisition ranked as the highest factor, with a mean score of 4.70, which affects the equipment management capability of firms. The results also showed that 65% of firms cannot outright purchase construction equipment, 56% rely largely on renting, and 62% often adopt an outsourced maintenance approach rather than in-house maintenance. This explains why many construction projects do not always benefit fully from the potential or output of construction equipment. The study argues that construction projects can benefit maximally from the potential of construction equipment when construction firms leverage their capabilities and project resources prudently. The study contributes to knowledge by shifting the debate in the literature on equipment and focusing on capabilities. The study has implications for construction firms that seek to develop capabilities that can promote their business interest and competitive advantage.
