Challenges in the Implementation of Modern Methods of Construction, Including Construction 3D Printing, in South Africa: A Comprehensive Examination of Products Performance

Abstract: South Africa's national building regulations currently accommodate conventional building products compliant with specified standards in South African National Standards. Additionally, provisions are made for Innovative Building Technologies (IBT), including Modern Methods of Construction and Construction 3D Printing, which must adhere to Agrèment South Africa's performance requirements. These IBTs undergo rigorous certification processes encompassing structural strength, stability, fire resistance, and thermal performance assessments. While various IBTs have received certification and found application in housing, schools, and clinics, a gap persists in translating research and knowledge into widespread implementation. This paper focuses on establishing a knowledge base for IBT building walling products, particularly those related to Modern Methods of Construction and Construction 3D Printing, certified by Agrèment SA. The research methodology involves data collation and analysis from Agrèment SA, categorizing products based on building occupancy and performance through a stratification process. Validation of certificate data was conducted through interactions with system owners. The study also reviews challenges hindering the implementation of some certified products, emphasizing the specific context of Modern Methods of Construction and Construction 3D Printing. The paper concludes with a recommendation for a conceptual framework integrating research, knowledge dissemination, innovation, government involvement, and market diffusion to address these challenges and facilitate effective implementation.
