    (International Journal on Emerging Technologies, 2020) Aduwo, E.B; Ibem, E.O; Ayo-Vaughan, E.A; Afolabi, A.O; Uwakonye, U.O; Oluwunmi, A.O
    Electronic (e-) Procurement has been acknowledged as one of the technologies capable of promoting efficiency in supply chain management in the construction industry in the developing countries. However, there is a scarcity of empirical studies on the implementation of this technology in the construction sector of many developing countries, including Nigeria. Consequent upon this there is a lack of understanding of the factors prospective users need to give attention for a successful implementation of e- Procurement in the acquisition of construction works, services and materials/equipment in Nigeria. This study, therefore investigated the determinants of e-Procurement implementation in construction business in Nigeria. The research was based on the administration of structured questionnaire to a randomly selected 759 users of this technology in the six geo-political zones in Nigeria. The data were analysed using frequency and percentage distributions and categorical regression analysis. The results revealed that whereas e-Procurement implementation in construction business in the study area varied with organizational characteristics, the key determinants of implementation of this technology amongst construction entities were the organizations’/firms’ role and areas of construction procurement experience, lower transaction cost, challenges associated with signing electronic contracts, reliability and security of e-Procurement systems and processes. This study is instructive in noting that for a sustained use of e-Procurement in construction business, organizations/firms in Nigeria and other developing countries should as a matter of necessity give adequate attention to issues such as their role in the industry, areas of their construction procurement experience, the number of offices they have, availability of reliable and secured electronic systems and applications, cost of Internet services and acceptability of electronic contracts.

    Electronic (e-) Procurement Adoption and Users’ Experience in the Nigerian Construction Sector
    (International Journal of Construction Education and Research, 2020) Ibem, E.O; Aduwo, E.B; Afolabi, A.O; Oluwunmi, A.O; Tunji-Olayeni, P.F; Ayo-Vaughan, E.A; Uwakonye, U.O
    The adoption of e-Procurement in construction is gaining global accept- ability, but in a developing country like Nigeria, there is a paucity of studies on the e-Procurement tools/applications used by construction industry stakeholders and their experiences with this technology. This study investigated e-Procurement adoption and users’ experience with it in the Nigerian construction industry using a questionnaire survey of 759 users of e-Procurement. The data were analyzed using descriptive statistics and factor analysis and the results show that whereas relatively high usage of e-Procurement tools in sending and receiving information on tender opportunities, tendering, and making and receiving pay- ments for construction procurement transactions was observed, the use of this technology in monitoring the progress of work on construc- tion sites or tracking the movement of materials was very low. It was also observed that users’ experience with e-Procurement in Nigeria was influenced by the adequacy and reliability of Internet infrastructure and ease of use of the technology, operational environment, change management issues, benefits of the technology, and the availability, accessibility, and interoperability of e-Procurement systems. The study implies that in order to ensure sustained use of e-Procurement in Nigeria’s construction sector, adequate attention should be given to these factors that influence users’ experience.
