Construction Projects are complex and high stakes. These Projects carry numerous risk elements, including but not limited to Scope of Works (SOW), Design Philosophy, Site Conditions, Weather, Interface Matrix, and express or implied contractual provisions. To effectively mitigate or (alleviate) these associated risks, Contract serves as the ultimate guide as it defines the rights, responsibilities, and obligations of Parties involved, establishing the framework for risk allocation, payment structures, timelines, and dispute resolution.
