“In order to bridge the gap between the digital and the physical construction needs to become a leaner manufacturing process, We need to adopt principles and practices from other six sigma manufacturing sectors and adapt them to construction."Construction is one of the world’s largest industries as it addresses the fundamental human need for shelter.
