C.R.S. § 8-17-107: Federal and state law.

Nothing in this article applies to any project that receives federal moneys. In addition, nothing in this article contravenes any existing treaty, law, agreement, or regulation of the United States. Contracts entered into in accordance with any treaty, law, agreement, or regulation of the United States do not violate this article to the extent of that accordance. The requirements of this article are suspended if such requirement would contravene any treaty, law, agreement, or regulation of the United States, or would cause denial of federal moneys or preclude the ability to access federal moneys that would otherwise be available.
