I would say, firstly, the construction industry has a reputation for going over-budget and over-time. The difference is they are much less likely to have stuff that's not fit for purpose at the end of it (although there are exceptions). The reasons for that? There's thousands of years of experience in humankind of various types of construction and in-depth knowledge of the materials. Whereas in software we've only got 60-odd years of experience and the materials we use are generally untested. On top of that, when they use new materials in construction, there is a legal and engineering requirement to test those materials before they are used generally. In software we just go "ooh, look new Javascript framework" and dive on straight away.
