    Condition Surveys and Assessment of Buildings: A Review of Approaches Adopted
    (Proceedings of the 5th International Conference of School of Environmental (SETIC 2024), October, 2024, School of Environmental Technology, Federal University of Technology Minna. PMB 65, Minna, Niger State Nigeria., 2024-11-07) Abass Abdulshakur; Olubajo Oluseun Olukemi
    Building condition surveys and assessment is increasingly becoming an important issue. This is because people spend a lot of time residing or working in buildings and knowledge of the condition of a building can reduce the likelihood of fatalities in the event of a disaster or building collapse. Research on building condition surveys and assessment tends to adopt varying approaches that seems to be contradicting. This study aims at examining the dominant research approaches on building condition surveys/assessment and to underline their assumptions, limitations and arguments. A review of the literature on condition surveys and assessment of building is executed. This literature is categorised into major themes, synthesised and the typical focus is challenged. The results show that four dominant approaches have been adopted in literature namely: model-based approach, fuzzy theory approach, condition index approach and the digital approach. The study argues that a combined or hybrid approach provides an alternative approach that will unearth reliable data on a building that can be triangulated or validated by comparing the different data on the condition of a building.

    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.
