(1) create a private cause of action;
(2) be a precondition to judicially enforcing an obligation under a construction payment bond;
(3) diminish any other obligation of a surety company that exists by law; or
(4) prohibit a surety company from asserting a defense against a construction payment bond claim in a proceeding to enforce a claim.
