Maybe the way to do it is to not try to write hyper-detailed regulations specifying the type and color or finishes, etc, as HRM planners are wont to do. Requirements that specify more of a "spirit and intent" approach, either site-specific or more broadly, that call for things to be a certain standard will soon be understood by developers and designers and hopefully result in better proposals. It would take some creativity, rare in bureaucrats, but it can be sone.
