Airports are built to fit the space they're allocated. And runways have to be sited accounting for approach patterns that can be many hundreds of miles. Given the variation in geography of the planet Earth there's zero one-size fits all construction that can be done. Airports are standardized to the degree they can be standardized. There are entire sections of the Human Factors and Ergonomics Design Handbook devoted to airport terminals and other large transportation spaces. But these spaces have to be designed to fit the place that they are constructed in.
