The actual installed work never varied more than an astoundingly precise 3 millimeters from the digital model. This accuracy allowed for an amazingly fast lego-like assembly installation process where very little onsite measuring, drilling or cutting was required. A large number of relatively unskilled and affordable workers were unleashed to accelerate the installation process. This degree of factory pre-fabrication is unprecedented for such a large and complex installation, propelling the Maker paradigm into large construction technologies
