ABSTRACT
The construction industry is faced with challenges from design, construction and maintenance of a facility. The study investigates the characteristics of buildability and maintainability analysis of architectural designs with a view of promoting effective project delivery and maintenance. Relative Importance Index (RII) and ranking method were used to determine the most important factors or features of buildability and maintainability that improves and promotes efficient project delivery. The study reveal that the five (5) top buildability and maintainability factors are as follows: personnel skill, handling, details, dimensional/modular coordination and conversion. The study also identified lack of awareness of clients, unskilled professionals using foreign technology and adopting such technological advancement on current designs, lack of good law/enforcement on building practice in Nigeria, problem of monitoring and supervision by relevant government agency, compromising of building standards and the use of inferior materials in construction as some of the factors affecting the implementation of buildability and maintainability analysis in architectural designs. The study concludes that most approved building project designs in Jos metropolis contain one or more buildability and maintainability problems, thus, the research recommends an enlightenment campaign for key project stakeholders with respects to the adoption of buildability and maintainability principles and practices so as to take advantage of its benefits in improving project delivery.
