ABSTRACT
Despite the significant contribution of the construction industry to Nigeria’s Gross Domestic Product (GDP), the sector continues to experience persistent cha
llenges, including poor construction quality and recurrent building failures. These challenges have been partly attributed to the prevalence of informal construction practices, which undermine architectural documentation. This study investigates the influence of informal construction practices on architectural documentation in Abia State, Nigeria. A mixed-methods research design was adopted, integrating quantitative and qualitative approaches. Data were collected from 150 respondents—comprising architects, contractors, and clients-using structured questionnaires and semi-structured interviews. Quantitative data were analyzed using descriptive and inferential statistics, while qualitative data were examined through thematic analysis. The findings reveal that informal construction practices, particularly unauthorized design changes, inadequate site supervision, and poor record-keeping, are moderately prevalent. Architectural
documentation was perceived as moderately adequate; however, significant deficiencies persist. The results further indicate a statistically significant relationship between informal construction practices and architectural documentation (r = 0.65, p < 0.05), with regression analysis confirming that informal practices significantly predict variations in documentation quality (β = 0.401, p < 0.05). Qualitative findings highlight weak regulatory enforcement, corruption, poor site management, and inadequate documentation systems as major challenges. The study concludes that informal construction practices significantly undermine the accuracy, completeness, and reliability of architectural documentation. It is recommended that regulatory enforcement be strengthened, documentation processes standardized, and capacity-building initiatives implemented for construction stakeholders. Additionally, improved site supervision and anti-corruption measures are essential for enhancing compliance and
improving overall construction quality.
