No, no-damages-for-delay clauses are void against public policy per Ohio Rev. Code §4113.62 C(1).
The code states that any provision of the construction contract, “that waives or precludes liability for delays during the course of a construction contract when the cause of the delay is a proximate result of the owner’s act or failure to act, or that waives any other remedy for a construction contract when the cause of the delay is a proximate result of the owner’s act or failure to act, is void and unenforceable as against public policy.”
