Physical projects have a construction phase, because they don't have the luxury of zero-cost copying. If you want to construct two identical houses, you still need people to lay bricks twice. If you want two identical websites, you deploy the same files twice. By the nature of software the "construction" part doesn't really apply. If you only replicate already-designed pieces of software, that's more like creating accounts in SaaS or deploying code to new servers.
