OPINION
DAMICH, Chief Judge.
I. Introduction
On February 16, 2007, Defendant filed a Motion for Reconsideration of the Court’s February 2, 2007, opinion on the parties’ cross-motions for summary judgment. AAB Joint Venture v. United States, 75 Fed.Cl. 414 (2007). The Court’s earlier opinion found in favor of Plaintiff on the issue of liability due to defective specifications, leaving only a determination on the amount of damages remaining. Pursuant to an order by the Court, Plaintiff filed a response to Defendant’s Motion for Reconsideration on March 9, 2007, and Defendant filed a reply to Plaintiff’s response to Defendant’s motion on March 16, 2007. For the reasons set forth below, Defendant’s motion is DENIED.
II. Standard for Decision
Reconsideration of a prior decision by the court is grounded in Rule 59(a)(1) of the Rules of the U.S. Court of Federal Claims (“RCFC”).1 The decision whether or not to grant a motion for reconsideration is in the sound discretion of the trial court. Yuba Natural Res. v. United States, 904 F.2d 1577, 1583 (Fed.Cir.1990); Chippewa Cree Tribe of the Rocky Boy’s Reservation v. United States, 73 Fed.Cl. 154, 157 (2006); Henderson County Drainage District No. 3 v. United States, 55 Fed.Cl. 334, 337 (2003); Franconia Assocs. v. United States, 44 Fed.Cl. 315, 316 (1999); Fru-Con Constr. Co. v. United States, 44 Fed.Cl. 298, 301 (1999); Seldovia Native Assoc. Inc. v. United States, 36 Fed.Cl. 593, 594 (1996). The court must exercise extreme care in deciding such a motion. Carter v. United States, 207 Ct.Cl. 316, 518 F.2d 1199, 1199 (1975); Chippewa Cree Tribe, 73 Fed.Cl. at 157; Henderson County Drainage, 55 Fed.Cl. at 337; Fru-Con Constr., 44 Fed.Cl. at 301; Seldovia Native Assoc., 36 Fed.Cl. at 594. The purpose served is not to afford a party dissatisfied with the result an opportunity to reargue its case. Roche v. District of Columbia, 18 Ct.Cl. 289, 290, 1800 WL 1263 (1883); Chippewa Cree Tribe, 73 Fed.Cl. at 157; Henderson County Drainage, 55 Fed.Cl. at 337; Fru-Con Constr., 44 Fed.Cl. at 301; Seldovia Native Assoc., 36 Fed.Cl. at 594; Principal Mutual Life Ins. Co. v. United States, 29 Fed.Cl. 157, 164 (1993); Bishop v. United States, 26 Cl.Ct. 281, 286 (1992). A motion for reconsideration “is not intended to give an unhappy litigant an additional chance to sway the court.” Circle K Corp. v. United States, 23 Cl.Ct. 659, 664-65 (1991); see also Chippewa Cree Tribe, 73 Fed.Cl. at 157; Henderson County Drainage, 55 Fed.Cl. at 337; Fru-Con Constr., 44 Fed.Cl. at 301; Bishop, 26 Cl.Ct. at 286.
The moving party must support its motion for reconsideration by a showing of exceptional circumstances justifying relief, based on a manifest error of law or mistake in fact. Henderson County Drainage, 55 Fed.Cl. at 337; Fru-Con Constr., 44 Fed.Cl. at 300; Chippewa Cree Tribe, 73 Fed.Cl. at 157; Franconia Assocs., 44 Fed.Cl. at 316; Seldovia Native Assoc., 36 Fed.Cl. at 594; [705]*705Principal Mutual Life, 29 Fed.Cl. at 164; Bishop, 26 Cl.Ct. at 286. The motion must have one of the following bases: (1) an intervening change in controlling law has occurred; (2) previously unavailable evidence is now available; or (3) reconsideration is necessary to prevent manifest injustice. Chippewa Cree Tribe, 73 Fed.Cl. at 157; Henderson County Drainage, 55 Fed.Cl. at 337; Fru-Con Constr., 44 Fed.Cl. at 301; Bishop, 26 Cl.Ct. at 286.
III. Analysis
In its motion for reconsideration, Defendant apparently relies on the third basis, namely, that reconsideration is necessary to prevent manifest injustice. Defendant raises three principal arguments averring that the Court made a manifest error of law or mistake of fact in rendering its decision on the parties’ cross-motions for summary judgment. First, Defendant contends that the Court made a determinative finding of fact in Plaintiffs favor based on evidence that was not offered for the truth of its contents and that, if so offered, would have been inadmissible hearsay. Second, Defendant argues that the Court drew factual inferences in favor of Plaintiff as movant, contrary to summary judgment standards. Finally, Defendant argues that the Court made a determinative finding of fact in Plaintiffs favor without considering evidence offered by Defendant which clearly controverted this fact.
The Court notes that both parties switched positions during the course of briefing on the cross-motions for summary judgment, making the Court’s task of evaluating evidence and considering burdens of proof especially challenging.2
A. Consideration of Inadmissible Hearsay Evidence
Defendant first asserts that the Court, in its determination that the modified AASHTO compaction test could not be performed with the maximum 6-inch stone size, relied on the statement by Isotop Ltd. (“Isotop”), the subcontractor who performed the compaction test. Defendant contends that the Isotop statement was offered by Defendant, not by Plaintiff, and was not offered for the truth of its contents but rather as background information regarding the sequence of events leading up to Plaintiffs instruction to its subcontractor, Rolider Ltd. (“Rolider”), to limit the maximum stone size to 3 inches rather than 6 inches in the top 1.5 meters of fill. Defendant further contends that, upon offering the Isotop statement, Defendant expressly disputed the truth of its contents. If the statement had been offered for the truth of its contents, Defendant contends that it would have objected to its admission as inadmissible hearsay evidence. Defendant argues that, pursuant to RCFC 56(e), hearsay evidence may not be offered in deciding a motion for summary judgment.3 To support its argument, Defendant cites Scosche Indus., Inc. v. Visor Gear Inc., 121 F.3d 675, 680-81 (Fed.Cir.1997). In Scosche, the plaintiff produced, in opposition to the defendant’s motion for summary judgment, a declaration by Scosche’s president stating what a customer had told him. The court held that, because the declaration constituted hearsay and therefore failed to comply with Rule 56(e), it was insufficient to overcome the summary judgment motion.
The Court acknowledges that its opinion incorrectly suggested that it was Plaintiff, not Defendant, who provided the Isotop letter to the Court.4 The Court merely intended to establish that Plaintiff relied on the opinion of Isotop in determining that an incompatibility existed between the maximum stone size requirement and the designated compaction test in the contract. To the ex[706]*706tent that the opinion identified Plaintiff as the party that produced the letter, the Court hereby corrects the error. The Court further notes that Defendant’s Proposed Findings of Uncontroverted Fact stated:
In or around late 2001, ISOTOP stated to AAB that it could not test six inch (15cm) material for density according to the modified A.A.S.H.T.O. standard.

A. Consideration of Inadmissible Hearsay Evidence
Defendant first asserts that the Court, in its determination that the modified AASHTO compaction test could not be performed with the maximum 6-inch stone size, relied on the statement by Isotop Ltd. (“Isotop”), the subcontractor who performed the compaction test. Defendant contends that the Isotop statement was offered by Defendant, not by Plaintiff, and was not offered for the truth of its contents but rather as background information regarding the sequence of events leading up to Plaintiffs instruction to its subcontractor, Rolider Ltd. (“Rolider”), to limit the maximum stone size to 3 inches rather than 6 inches in the top 1.5 meters of fill. Defendant further contends that, upon offering the Isotop statement, Defendant expressly disputed the truth of its contents. If the statement had been offered for the truth of its contents, Defendant contends that it would have objected to its admission as inadmissible hearsay evidence. Defendant argues that, pursuant to RCFC 56(e), hearsay evidence may not be offered in deciding a motion for summary judgment.3 To support its argument, Defendant cites Scosche Indus., Inc. v. Visor Gear Inc., 121 F.3d 675, 680-81 (Fed.Cir.1997). In Scosche, the plaintiff produced, in opposition to the defendant’s motion for summary judgment, a declaration by Scosche’s president stating what a customer had told him. The court held that, because the declaration constituted hearsay and therefore failed to comply with Rule 56(e), it was insufficient to overcome the summary judgment motion.
The Court acknowledges that its opinion incorrectly suggested that it was Plaintiff, not Defendant, who provided the Isotop letter to the Court.4 The Court merely intended to establish that Plaintiff relied on the opinion of Isotop in determining that an incompatibility existed between the maximum stone size requirement and the designated compaction test in the contract. To the ex[706]*706tent that the opinion identified Plaintiff as the party that produced the letter, the Court hereby corrects the error. The Court further notes that Defendant’s Proposed Findings of Uncontroverted Fact stated:
In or around late 2001, ISOTOP stated to AAB that it could not test six inch (15cm) material for density according to the modified A.A.S.H.T.O. standard. ISOTOP subsequently confirmed this assertion in writing, by letter dated February 24, 2004.
Def.’s FF H13 (citations omitted). Thus, as in Scoscke Indus., Defendant, as the non-moving party, offered the Isotop letter attached to its opposition to Plaintiffs motion for summary judgment. However, in Scosche Indus., it was the moving party that objected to submission of hearsay evidence by the non-moving party. In contrast, here, Defendant, the non-moving party, is objecting to consideration by the Court of evidence introduced by itself, the non-moving party. Only now, after the Court has considered the Isotop letter in rendering its decision on the parties’ cross-motions for summary judgment does Defendant cry “hearsay.”
The law is clear that a party offering evidence “opens the door” and waives its right to object to the entry of that evidence. The immediate effect of introducing evidence is the loss of the right to exclude the evidence or to claim that admitting the evidence was other than harmless error. United States v. Washington, 434 F.3d 7, 11 (1st Cir.2006); United States v. Allen, 76 F.3d 1348, 1365-66 (5th Cir.1996); 1 Christopher B. Mueller & Laird C. Kirkpatrick, Federal Evidence § 12, at 48 (2d ed.1994). Thus, courts are generally on solid ground in refusing to let parties complain about evidence they themselves introduce. Mueller et al. § 12, at 49; see, e.g., Capobianco v. City of New York, 422 F.3d 47, 55 (2d Cir.2005) (finding that when defendants submitted unsworn letters in support of their motion for summary judgment they waived any objections to their admissibility).
Furthermore, on a summary judgment motion, the Court may consider evidence in a form that is not admissible for trial. Celotex Corp. v. Catrett, 477 U.S. 317, 324, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986). Hearsay evidence may be considered by a court provided the out-of-court declarant would be available to testify as to the evidence at trial, Tatum v. Cordis Corp., 758 F.Supp. 457, 463 (M.D.Tenn.1991), particularly if the evidence is corroborated or the court concludes that it is sufficiently reliable. DiMarco v. Rome Hosp. & Murphy Mem’l Hosp., 899 F.Supp. 91 (N.D.N.Y. 1995). Several federal courts either have allowed hearsay evidence, where the evidence could ultimately be cured by sworn affidavit or testimony, or have permitted an opportunity to cure the deficiency. Capo-bianco, 422 F.3d at 55 (finding that to exclude the letters would prejudice plaintiffs who otherwise could have obtained sworn affidavits reiterating what was in the letters); Maytag Corp. v. Electrolux Home Products, Inc., 448 F.Supp.2d 1034, 1063-64 (N.D.Iowa 2006) (holding that although un-sworn statements are generally inadmissible at the summary judgment stage, it may be possible to “cure” the deficiency of an un-sworn statement by providing a subsequent affidavit or testimony reiterating or reaffirming the opinions in the unsworn report); Straus v. DVC Worldwide, Inc., 484 F.Supp.2d 620, 633-34 (S.D.Tex.2007) (finding that while an unsworn expert report did not constitute admissible summary judgment evidence, the deficiency was cured by the filing of a sworn declaration).
The Court finds that consideration of the Isotop letter was proper. Defendant, by introducing the Isotop letter into evidence, waived any subsequent right to object to its admissibility. Moreover, for the Court to have excluded the Isotop letter from evidence in rendering its decision on summary judgment would have prejudiced Plaintiff who otherwise could have obtained a sworn affidavit by Mr. Michael Shandalov, the author of the Isotop letter. The Court was free to consider the Isotop letter, particularly here, where the contents of the letter were corroborated by the modified AASHTO compaction test specifications and where the Court determined the letter to be reasonably reliable.
Defendant avers that because it offered the Isotop letter for another purpose and [707]*707voiced its concerns regarding the truth of its contents,5 it did not waive its right to later object to the letter as hearsay evidence, but Defendant fails to cite any authority to support this proposition. Further, the Court can find no authority to suggest that it is to consider each and every piece of evidence only for the purpose for which it was intended. To the contrary, courts are given wide latitude in considering any document of record in its analysis of a summary judgment motion, regardless of when the document was filed and for what purpose. For example, an affidavit that is on file in a case, regardless of the purpose for which it was prepared and filed, can be considered by the court in deciding a motion for summary judgment. See Carmona v. Toledo, 215 F.3d 124, 132 n. 7 (1st Cir.2000); McLaughlin v. Liu, 849 F.2d 1205, 1206 n. 3 (9th Cir.1988); McCullough Tool Co. v. Well Surveys, Inc., 395 F.2d 230, 236 n. 7 (10th Cir.1968); 10A Charles Alan Wright, Arthur R. Miller, Mary Kay Kane, Federal Practice & Procedure § 2722, at 378 (3d ed.1998). Therefore, the Court did not err in considering the Isotop letter in its overall determination of whether or not the contract specifications were defective.
Finally, even if the Court did err in considering the Isotop letter, it was harmless error because the Court did not rely solely on the Isotop letter in finding that the contract specifications were defective. The Court also relied on the AASHTO T-180 and ASTM D-1557 compaction test specifications, as discussed further below.
B. Inferences Made in Favor of Plaintiff
Defendant contends that the Court, in concluding that the modified AASHTO test could not be performed with fill containing 6-inch stone because the size of the mold was less than 6 inches,6 improperly inferred that 6-inch stone had to be utilized in the test. In so doing, Defendant contends that the Court improperly drew inferences in favor of Plaintiff, the moving party, regarding a factual issue not directly addressed by the evidence of record. Defendant argues that there is nothing in the AASHTO T-180 compaction test specification that prohibits exclusion of larger stones from the test specimen in performing the test. In a footnote, Defendant proffers that the Court failed to consider, for example, whether the use of a field test might obviate the need to use 6-inch stone in the modified AASHTO compaction test. Defendant avers that even if the inference made by the Court was permissible in denying Defendant’s motion for summary judgment, the inference was not permissible in granting Plaintiffs motion for judgment.
The Court disagrees that an improper inference was made. In fact, the Court disagrees that an inference was made at all. The Court simply explained, as background information, that the function of a compaction test is to determine the relationship between moisture content and soil density when exposed to a given compaction pressure in order to ascertain the moisture content that should be utilized when compacting the soil. This is well documented in both the AASHTO T-180 and ASTM D-1557 compaction test specifications. Pl.’s App., Ex. A, Attach. 12 If 1.1, Attach. 13 1T 1.1. The Court then went on to state that the size of the mold required to perform the modified AASHTO soil compaction test is smaller than the maximum stone size permitted by the contract. This is also clear from the compaction test specifications. Id. No inference whatsoever is required for the Court to [708]*708thereby state what is evident, namely, that the modified AASHTO compaction test cannot be performed with 6-inch stone. Although the Court also stated that the soil sample to be tested should be representative of the soil to be compacted, such a statement is hardly an inference at all. There is nothing remarkable about the scientific principle that a test sample should be representative of that which is to be tested. Defendant does not offer evidence to the contrary. Although Defendant proffers that 6-inch stone could be excluded from the sample and that the test could still be performed for its intended purpose, this argument is not backed up by supporting evidence.7 Moreover, Defendant notably fails to address the final issue raised by the Court in its opinion regarding the allowable proportion of fill of maximum stone size. The Court noted that while stone of maximum size (6 inches) was limited by the contract to 20% of total fill, there was no limitation on stone of less than maximum size, e.g., stone of 5.5 inches. So, for example, the contract allowed for the utilization of fill with a uniform size of 5.5 inches. Defendant fails to offer any evidence to show how such fill could effectively be tested with the modified AASHTO compaction test. The Court, therefore, did not err in concluding that there was an incompatibility between the designated compaction test and the maximum stone size and that the contract specifications were defective.
C. Failure to Address Evidence Showing Controverted Fact
Finally, Defendant asserts that the Court erroneously overlooked evidence offered by Defendant which controverts Plaintiffs evidence showing that it relied on the defective specifications and, hence, the Court failed to recognize that a genuine issue of controverted fact existed. Defendant argues that the Court, in its opinion, mentions only the declarations of Mr. Dennison S. Keeney and of Mr. Mordehai Rubenstein provided by Plaintiff in support of reliance, but ignores the evidence of non-reliance submitted by Defendant. In particular, Defendant points to the earlier deposition testimony of Mr. Keeney.8 Defendant contends that although Mr. Keeney attempts to explain away his earlier deposition testimony in his declaration, the deposition testimony still exists. According to Defendant, the declaration of Mr. Keeney does not trump his deposition testimony, but rather raises a genuine issue of controverted fact.9
[709]*709As stated in the Court’s opinion, a motion for summary judgment shall be granted “if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and the moving party is entitled to judgment as a mater of law.” RCFC 56(c); see Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 247-48, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986); Sweats Fashions, Inc. v. Pannill Knitting Co., 833 F.2d 1560, 1562-63 (Fed.Cir.1987). A genuine issue is one that “may reasonably be resolved in favor of either party.” Anderson, 477 U.S. at 250, 106 S.Ct. 2505. A material fact is one which might affect the outcome of the litigation under the substantive law. Id Here, while the Court determined that the issue of reliance was indeed a material fact, the Court concluded that there was no genuine issue.
Defendant has inferred that because the Court did not mention the Keeney deposition in its opinion, the Court did not consider it. However, the Court did in fact consider the Keeney deposition, but found that it was ambiguous and did not necessarily contradict the Keeney declaration. In fact, Keeney, in his declaration, clarified that his earlier testimony should not be construed to mean that AAB did not factor in the cost of crushing rock to 6 inches and no smaller in arriving at its bid price, but merely that neither party was aware of a problem with 6-inch stone during bidding. Based on the overwhelming evidence of reliance presented by Plaintiff and referenced in the opinion, the Court did not find that the issue could reasonably be resolved in favor of Defendant, but only in favor of Plaintiff.10 To the extent that the Court did not even mention the evidence presented by Defendant, the Court hereby corrects that omission. Nevertheless, the outcome remains the same and, by arguing the issue now on reconsideration, Defendant is essentially asking the Court to reconsider arguments which were made in its earlier briefs. The purpose served by a motion for reconsideration is not “to give an unhappy litigant an additional chance to sway the court.” Circle K, 23 Cl.Ct. at 664-65; see also Chippewa Cree Tribe, 73 Fed.Cl. at 157; Henderson County Drainage, 55 Fed.Cl. at 337; Fru-Con Constr., 44 Fed.Cl. at 301; Bishop, 26 Cl.Ct. at 286. In sum, the Court does not find that Defendant has successfully identified an error in the Court’s factual analysis regarding reliance.
IV. Conclusion
Defendant’s Motion for Reconsideration of the Court’s February 2, 2007, opinion is DENIED.
The Court ORDERS the parties to file a Joint Status Report on or before August 29, 2007, discussing how they propose to proceed.
