Unavoidable risks, on construction projects, which could affect their completion time?

Question

so far i have got:

weather conditions

wars

financially

economically

but are there other ones?

Answer 1

Permitting actions and environmental compliance issues may affect a construction project if not correctly addressed in any applicable environmental assessment or environmental impact statement.

Answer 2

For wars, civil or international, general strikes, calamities or natural disaster, Acts of God or the failure of third parties - such as suppliers and subcontractors to perform their obligations to the contracting party,  the term used is force majeure. Check  these link for further information on the subject: http://www.library.yale.edu/~llicense/fo...

Weather conditions - like rainy day and force majeure are the only acceptable unavoidable risk, which provide for an automatic adjustment to the completion date on a construction project.

So far, you've covered them except for the correct  terms.
