This could be because construction (civil engineering?) is a fairly mature field that's been around for hundreds of years. Of course there's new materials and designs and everything but there are also established methodologies and standard practices.
Add things generally go according to plan in Western countries so I'm not surprised. (I'm from a non-Western country where long term planning of anything is futile — too much entropy and chaos).
Computers, software etc is a very young field in comparison. By the year 4723 things would hopefully be standardized (and possibly build themselves).
