what exactly is a construction technique in relation to art history?
Not sure I understand the question, but the one art history course I took in college had a huge, huge emphasis on architecture (which I could have taken a course in instead had I been interested in architecture).
Bricklaying and masonry, essential to many construction techniques, can be artforms.
Not sure I get the question either, but maybe something like the evolution from poat-and-lintel to arches, and then the creation of the gothci (pointy-arch) aesthetic? If you elaborated on the question, it might help.
