# 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.
