evidence: A way that builders, especially in India, solve this problem of uncertainty is through political connections. If you are assuming honest businessmen at work, think lobbying, campaign finance, etc., and if they are closer to real-world builders in India, then explicit corruption, bribes, kickbacks, Swiss bank accounts etc., to make sure that the codes on which the blueprint was made won’t change, no new regulations or inspections will be introduced, that the police will get rid of any environmental groups protesting, and so on.
