    Adoption and Barriers of Engineered Bamboo Products in the Nigerian Construction Industry
    (Horizon Research Publishing (HRPUB), 2025) Amusan, Lekan M.; Ojelabi, Rapheal A.; Omuh, Ignatius O.; Ogunrinde, Olugbenro
    The rise in the cost of conventional construction materials and the greenhouse effect from construction activities have been an issue of concern to stakeholders in the construction industry. Hence, efforts have been concentrated on developing low-cost, environmentally friendly and sustainable local materials to mitigate the greenhouse effect. The quest for the sustainable materials necessitates the study to examine the prospects of adoption of engineered bamboo products and the challenges militating against its use among construction professionals. A quantitative approach was adopted and 70 questionnaires were distributed among construction professionals with structural engineering background in selected firms across Lagos State. Data collected were processed using percentage, mean item score and KruskalWallis’s test. Facts garnered from the study revealed that engineered bamboo adoption for construction related works like ceiling, flooring, and reinforcement among others is not outstanding. The poor implementation of the engineered bamboo products is attributed to some challenges which include ‘high affinity for conventional materials’, ‘unavailability of bamboo products’ and ‘lack of machinery to refine raw bamboo’ among others. Therefore, the study recommends that stakeholders need to channel more resources into research and development and creating an enabling policy that can enhance the bamboo products adoption.

    PROJECT MANAGEMENT COMPETENCIES OF INDIGENOUS CONTRACTORS IN NIGERIA
    (2016) Tunji-Olayeni, Patience; Mosaku, Timothy O.; Fagbenle, Olabosipo I.; Amusan, Lekan M.
    All over the world, governments are talking about reducing spending of capital and recurrent expenditures. Capital expenditures cover cost for major projects such as infrastructure. Moreover, the wealth and worth of a nation is a function of the availability and quality of its infrastructure. It has been noted that indigenous construction firms do not represent a strong source of competition. Consequently, most construction markets in Africa are dominated by expatriates. Governments of most African countries pay huge amount of money to expatriates because of deficiencies in indigenous capacity. This study therefore, identifies and analyses project management competencies required by indigenous construction firms. A quantitative research method was adopted for the study and 72 questionnaires were distributed to indigenous construction firms in Lagos and Abuja, Nigeria. This study revealed cost management, site management, and time management as the most critical project management competencies of indigenous contractors surveyed. The study further revealed that the critical PM competencies of contractors surveyed are hard/technical competencies. The study recommends that indigenous contractors should in addition to hard competencies develop soft/personal competencies which can also facilitate the achievement of project success.
