The high cost and environmental and health hazards attributed to conventional building materials, coupled with the adverse effect of massive exploitation of forest resources for construction purposes, have necessitated the search for alternative construction materials that are eco-friendly, sustainable, economical and socially acceptable. This study aims to explore the acceptability and use of innovative bamboo products for residential building construction in Nigeria. One hundred and fifty-two survey questionnaires were distributed to built environment professionals within the Lagos region using the convenience sampling technique. The results show a likely disposition to the use of innovative bamboo products for building construction, except for roof beams and trusses, wall beams and columns, and composite roofing sheets. Major barriers to the acceptability and use of bamboo for construction include lack of knowledge about bamboo connections and detailing; the absence of governmental policy on bamboo as an alternative construction material; the absence of design standards for bamboo products; and poor public perception of the use of bamboo in building construction. The value of this study is that it provides an excellent platform for further research on the optimization of bamboo for construction, which will boost economic activities, reduce capital flight for the importation of machinery and the constituents of conventional building materials, and enhance the country's GDP.

Extant literature has confirmed the unavoidability of changes to the design of construction projects. These changes have also been identified as major reasons for project cost, quality, and time failure. Despite BIM’s documented capabilities to enhance project success, its implementation remains unsatisfactory in Nigeria. This paper, therefore, examines the impacts of BIM-based design workflow in consulting business on construction project design performance. Using questionnaire as the research instrument, quantitative survey research was adopted to collect data from consulting organizations. Analysis revealed sequential and concurrent workflows as the most used and preferred, respectively. Design coordination, information, and communication are enhanced with sequential workflow within a firm, while concurrent metrics are enhanced when collaborating with other firms. Both workflows are jointly declared suitable for the timely delivery of designs. The study, therefore, recommended retraining of professionals on sequential and concurrent workflows because of their appropriateness for efficient design within and among firms.
