> Why single out weather? Lots of human activities are impacted by weather. What's the analogy to software? To point out there's still a large variable in the construction projects isted, and it's not as cut and dried as you made out. Here in the UK (land of rain) the weather is a major source of extra costs in small (under £1M) projects. Source: chief surveyor of a county council's highway department. The contracts are well negotiated by the construction firm (and I understand is an industry standard clause, so you can't just hire a different firm), so if work can't be done on your project due to inclement weather, they will put in a claime for their labour costs for thse days, plus hire of plant that's on-site. AFAIK they won't get the full cost, but they're good at putting in frequent claims :)
