The study aims to assess design specification and its’ impact on building sustainability in Akwa Ibom State. The study used Ex-Post-Facto design. The targeted population for the study comprised of all Architects in Akwa Ibom State. A stratified random sampling technique was used to select 30 Architects from Uyo senatorial district and 25 architects each from Ikot Ekpene and Eket Senatorial Districts. which gave a total of 80 respondent used for the study. The instrument used for data collection was a structured questionnaire titled: Design Specification and building sustainability Questionnaire (DSBSQ). Face and content validation of the instrument was carried out by an expert in test, measurement, and evaluation in order to ensure that the instrument has the accuracy, appropriateness, and completeness for the study. The reliability coefficient obtained was 0.91, and this was high enough to justify the use of the instrument. The researcher subjected the data generated for this study to appropriate statistical techniques such descriptive statistics. The study revealed that design specification is essential to ensure building sustainability in Nigeria. The researcher concluded that design specifications plays a crucial role in architectural planning and construction practices as it provides a roadmap for projects, detailing materials and methods for implementation. It was also concluded that prioritizing sustainability in construction processes can build a resilient, environmentally conscious future for Nigeria which is essential in improving the economic and social well-being of the nation. Also, the extent of design specification adoption in building construction in Akwa Ibom State is very low especially in the case of building construction undertaken by non-professionals. Finally, there are many roles of design specification in mitigating building collapse and promoting building sustainability in Akwa Ibom State, including “choosing the right building assembly to utilise in various building parts”. One of the recommendations was that architects, engineers, and other stakeholders involved in construction projects should ensure strict adherence to design specifications throughout the building process.
