During his 19+ years in modular construction and prefabricated building industry, Cetin has taken part in all phases of Pre Construction, Design, Manufacturing, Build and General Construction processes in more than 50 projects on 5 continents, ranging from 1 m $ to 400 m $.Thanks to the international projects he participated in, he carried out his work in accordance with many different regulations such as IBC, NFPA, BS, ISO, ASHRAE, AISC, ASCE, SNIP, EUROCODE, BOMBA and led his team. As a design coordinator and consultant, he reflected the knowledge he gained through training in different fields such as BIM, building physics, fire safety design, corrosion protection and structural analysis, to project and design management and specialized in these areas as an architectural engineer.Cetin, as a passionate defender of the contribution of modular construction technologies and digitalization to the transformation of existing construction processes, carries out many studies related with the off-site construction methodology where construction and production processes are carried out together, including BIM-ERP integration, lean production, DFMA (Design for manufacture and assembly), optimization and design automation.Specialties: Prefabrication, Modular Design & Construction, Industrialized Construction, Integrated Design, Integrated Project Delivery, Lean Construction, Steel Buildings, Light Gauge Steel Buildings, BIM, DFMA
