Because Plaintiffs failed to submit their claims to the contracting officer, and ipso facto, the contracting officer was not given an opportunity to address these claims, the Court lacks jurisdiction. See United Constructors, LLC v. United States, No. 08-757C, 2009 WL 875358, *1, *8 (Fed. Cl. Mar. 27, 2009) (dismissing claims without prejudice because "no proper CDA claims were presented to the contracting officer"); Amtec Corp. v. United States, 69 Fed. Cl. 79, 84 (2005), aff'd, 239 Fed. Appx. 585 (Fed. Cir. 2007) (dismissing an action without prejudice because "[a] final decision of a contracting officer is a prerequisite for bringing an appeal to this Court"). Without jurisdiction, "the only function remaining to the court is that of announcing the fact and dismissing the cause."
