Which areas one should pay more attention to in agreements or contracts?

[Vijay Kurhade]

Construction agreements or contractors are of different types with so many different terms; apart from Legal help as an expert 

Which are some of the areas/terms you think if not paid attention and understood properly results in risk potentials?

Any real life cases experienced which could help understand them without violating any NDA; please do share them (remove all confidential important data)

Thanks in Advance
