1. Introduction
Buildability terminology is an expression adopted for the effect of design on construction. The term “Buildability” is not well known and not in the dictionaries, although, in practice, the idea has been recognised right from the start of construction industry (Aina and Wahab, 2011). Buildability has been defined by the Construction Industry Research and Information Association (CIRIA) as “the extent to which the design of a building facilitates ease of construction, subject to the overall requirements for the completed building” (Zakaria et al., 2013). However, the key function of buildability analysis of building projects is to examine critically the production information with the view to identify, evaluate, prepare report, discuss the report with designers and ensure the removal of waste, wasted efforts and impediment to construction from design before work starts on site (Bamisile, 2013). These procedures are achieved by way of amending the characteristics of the design and changing specifications (Mydin et al., 2011; Bamisile, 2013). Buildability takes into account all phases of construction project and enables the optimum utilisation of construction resources (Singhaputtangkul and Low, 2015). The concept of buildability has been tested, used in several countries across the globe and confirmed to be very effective at optimising overall cost throughout the project life cycle (Aina and Wahab, 2011). For instance, the concept has been extensively being developed and applied in the USA, UK, Australia and Singapore, where their studies have demonstrated that improved buildability has led to significant savings in both cost and time required for completing construction projects (Mydin et al., 2011). Aina and Wahab (2011) asserted that integration of good buildability into good overall design is the responsibility of the design team, and involving people with construction knowledge and experience at the very beginning of the project results in maximising benefits.
Buildability is more progressively becoming a key necessity in construction practice (Afolabi and Oyeyipo, 2017; Mydin et al., 2011). Construction industry in the developing countries of which Nigeria is among, should not be denied the benefits of buildability analysis. Osuizugbo (2020) defined lack of buildability analysis as a total dearth of production information assessment to establish its production-friendly, suitability and defects free from the design stage before work commences on site. The concept...
