I suspect that ‘construct’ is preferred when we deal with for more abstract e.g.. “construct an idea”, “construct the events happened 20 years ago” etc. ‘build’ is often used with something physically e.g. a stone. How do I build structure, build lab etc.? I come across many sentences where how build is used with an analogous word like ‘build the argument’, ‘build the character’ etc. And

other example words like ‘build the argument’ etc.
