--- id: aliases: [] tags: - topic/risk title: Gold Plating --- # Gold Plating Gold plating, also "overengineering", is the frustratingly common design practice of arbitrarily requiring components or methods far more stringent than typical. In [[construction-estimating]], such cases quickly reveal every error of assumption made by the estimator. > [!example] Aluminum Feeders ILO Copper > The typical value engineering option for electrical installations > is to use aluminum wiring in lieu of copper above a certain size. > Assuming competent installation, > such an option is strictly functionally equal to the design. > There is _no_ difference to capacity, future expansion, or long-term maintenance. > Moreover, the substitution is invisible to the client, > such that they would have to employ an electrician > to determine whether it had been taken. > Despite this, copper wiring is still a common specification default > because clients care about that sort of thing for some reason.
