Over the years, the concept of precast systems has evolved and has become widely popular. While most systems look at an industrial, mass production lens for the same, they end up becoming inevitably limited to urban contexts only. This manual allows for a Precast system to be laid out in a way that skilled or unskilled masons can the execute the techniques with minimal industrial production in remote or rural landscapes. The manual has been developed based on the system conceptualized by Kruthica Architects in Hyderabad, India; along with the structural validation from Mahijaa Consultants in Bangalore, India.
