Why we need architecture of tolerance

Professor and Chair in Integrated Design at the University of Calgary Faculty of Environmental Design, Branko Kolarevic has established an international reputation as an author and commentator on digital design and manufacturing in architecture. Here he questions the importance of high-definition tolerance in construction itself. As an industry that operates at far greater sizes and scales than other manufacturing bases, has the 'messy world of building' not always had to allow for a reasonable tolerance of errors? Should high-definition processes, which negate or negotiate zero tolerance, really be for architects and construction professionals the Holy Grail that they first appear?
