Defendants First Bank and First Troy, SPE, LLC, appeal from an order granting summary judgment in favor of Plaintiff Ramey Kemp & Associates, Inc., with respect to its breach of contract, quantum meruit, and lien enforcement claims. On appeal, Defendants contend that the trial court erred by entering summary judgment in Plaintiffs favor on the grounds that Plaintiff failed to file a claim of lien within 120 days of the date upon which it last furnished labor or materials under the relevant contract and that the work that Plaintiff performed lacked the necessary nexus to an improvement to real property. After careful consideration of Defendants’ challenges to the trial court’s order in light of the record and the applicable law, we conclude that the trial court’s order should be affirmed.
I. Background
A. Substantive Facts
On 10 August 2005, Plaintiff entered into a “contract at the request of Steve Saieed, [an] authorized representative of Richmond Hills Residential Partners, LLC,” under which Plaintiff was obligated to furnish “labor, materials and equipment necessary to complete pro*399fessional design services in regards to traffic engineering services,” including, but “not limited to, preparing design plans, pavement marking and signing plans, drainage, sedimentation and erosion control designs, driveway designs, signal designs and encroachment agreement[s]” for a project under development by Richmond Hills. The services that Plaintiff performed “were not piecemeal and subject to separate contracts or work orders, but constituted a single Contract, and all work was identified by the same Ramey Kemp Project Number (05128.0).”1
Pursuant to the terms of this contract, Plaintiff performed various services which were primarily intended to assist Richmond Hills in obtaining the necessary driveway permits for the proposed development. “[T]he project stopped when the economy fell apart,” an event which had occurred by January, 2009. On 16 January 2009, the North Carolina Department of Transportation voided the permits authorizing the construction of one of the driveways providing access to the development due to the low level of construction activity occurring at that location. Plaintiff was “paid on this project up until January 28, [2009.]” However, Plaintiff “continued to do work from then through February of 2010” despite the fact that it did not receive payment for these additional services. “The last work performed by Plaintiff on the property was at the specific request of Steve Saieed on behalf of Richmond Hills” in February 2010 and included a “status report on outstanding or unresolved issues such as roadway improvements, driveway permits, and control-of-access agreements to facilitate a sale of the property.” In other words, Mr. Saieed had requested that the February 2010 letter be prepared because another person or entity was interested in purchasing the property and because such a letter was needed for the purpose of marketing the property that Richmond Hills had intended to develop.
As part of the process of funding the development of the proposed project, Richmond Hills obtained a loan from First Bank in the amount of $7,750,000.00. In return, Richmond Hills executed a deed of trust applicable to the property on which the development was to be located in favor of First Bank for the purpose of securing the loan.. *400After Richmond Hills defaulted on its obligation to First Bank, First Bank purchased the property at a foreclosure sale on 26 February 2010. On 26 June 2010, First Bank conveyed the property to Defendant First Troy.
B. Procedural History
On 30 March 2010, Plaintiff filed a claim of lien against the Richmond Hills property in which it asserted that it had last provided labor or materials for the proposed project on 24 February 2010. On 19 August 2010, Plaintiff filed a verified complaint against Richmond Hills, First Bank, and First Troy in which it asserted claims for breach of contract, quantum meruit, and enforcement of its lien claim. On 14 December 2010, First Bank and First Troy filed an unverified answer in which they denied the material allegations of Plaintiffs complaint. In addition, First Bank and First Troy asserted a third-party complaint against Mr. Saieed in which they (1) alleged that Mr. Saieed had filed an affidavit in which he falsely represented that there were no outstanding debts that might give rise to a claim of lien on the property; (2) sought indemnification for any judgment that Plaintiff might obtain against them arising from Plaintiffs claim of lien; and (3) asserted that they were entitled to recover damages from Mr. Saieed pursuant to N.C. Gen. Stat. § 75-1.1.
On 25 May 2011, an entry of default was made against Richmond Hills. On the same date, Plaintiff filed a motion seeking the entry of summary judgment in its favor against First Bank and First Troy and the entry of a default judgment against Richmond Hills. An affidavit executed by Montell Irvin, the president of Ramey Kemp, and various invoices and other documents were attached to Plaintiffs motion. On 25 August 2011, Defendants filed a response to Plaintiffs motion, which was accompanied by Mr. Irvin’s deposition and various documentary exhibits, including a 27 January 2009 letter from the North Carolina Department of Transportation voiding the “approved driveway permit application package” due to inactivity. Oh 3 October 2011, the trial court entered an order granting Plaintiff’s motion for summary judgment and entering default judgment against Richmond Hills. First Bank and First Troy noted an appeal to this Court from the trial court’s order granting summary judgment in Plaintiff’s favor.2
*401II. Legal Analysis
A. Standard of Review
Summary judgment is properly 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 that any party is entitled to a judgment as a matter of law.” N.C. Gen. Stat. § 1A-1, Rule 56(c). “All inferences of fact from the proofs offered at the hearing must be drawn against the movant and in favor of the party opposing the motion.” Boudreau v. Baughman, 322 N.C. 331, 343, 368 S.E.2d 849, 858 (1988) (citing Page v. Sloan, 281 N.C. 697, 706, 190 S.E.2d 189, 194 (1972). “A party moving for summary judgment may prevail if it meets the burden (1) of proving an essential element of the opposing party’s claim is nonexistent, or (2) of showing through discovery that the opposing party cannot produce evidence to support an essential element of his or her claim.” Lowe v. Bradford, 305 N.C. 366, 369, 289 S.E.2d 363, 366 (1982) (citations omitted). “[0]nce the party seeking summary judgment makes the required showing, the burden shifts to the nonmoving party to produce a forecast of evidence demonstrating specific facts, as opposed to allegations, showing that he can at least establish a prima facie case at trial.” Gaunt v. Pittaway, 139 N.C. App. 778, 784-85, 534 S.E.2d 660, 664, disc. review denied, 353 N.C. 262, 546 S.E.2d 401 (2000), cert. denied, 353 N.C. 371, 547 S.E.2d 810, cert. denied, 534 U.S. 950, 122 S. Ct. 345, 151 L. Ed. 2d 261 (2001). A trial court’s decision to grant summary judgment is reviewed on a de novo basis. Va. Electric and Power Co. v. Tillett, 80 N.C. App. 383, 385, 343 S.E.2d 188, 191, cert. denied, 317 N.C. 715, 347 S.E.2d 457 (1986).
According to N.C. Gen. Stat. § 1A-1, Rule 56(e), “[supporting and opposing affidavits [proffered in connection with a summary judgment motion] shall be made on personal knowledge, shall set forth such facts as would be admissible in evidence, and shall show affirmatively that the affiant is competent to testify to the matters stated therein. ...” Put another way:
*402“affidavits or other material offered which set forth facts which would not be admissible in evidence should not be considered when passing on the motion for summary judgment.” “Hearsay matters included in affidavits should not be considered by a trial court in entertaining a party’s motion for summary judgment. Similarly, a trial court may not consider that portion(s) of an affidavit which is not based on an affiant’s personal knowledge.” ... “A verified complaint may be treated as an affidavit if it (1) is made on personal knowledge, (2) sets forth such facts as would be admissible in evidence, and (3) shows affirmatively that the affiant is competent to testify to the matters stated therein.”
Wein II, LLC v. Porter, 198 N.C. App. 472, 476-77, 683 S.E.2d 707, 711 (2009) (quoting Strickland v. Doe, 156 N.C. App. 292, 295, 577 S.E.2d 124, 128-29, disc. review denied, 357 N.C. 169, 581 S.E.2d 447 (2003) (internal citation omitted); Moore v. Coachmen Industries, Inc., 129 N.C. App. 389, 394, 499 S.E.2d 772, 776 (1998); and Page v. Sloan, 281 N.C. 697, 705, 190 S.E.2d 189, 194 (1972) (citing N.C. Gen. Stat. § 1A-1, Rule 56(e)). As a result, while the trial court was entitled to consider the factual allegations in Plaintiff’s verified complaint in ruling on Plaintiff’s summary judgment motion, the same is not true of Defendants’ responsive pleading, which was not verified.
A careful reading of Defendants’ brief indicates that Defendants have not argued that the record disclosed the existence of any genuine issue of material fact. According to well-established North Carolina law:
Appellate review is limited to those questions “clearly” defined and “presented to the reviewing court” in the parties’ briefs, in which “arguments and authorities upon which the parties rely in support of their respective positions” are to be presented. See N.C.R. App. P. 28(a)[.]... “It is not the role of the appellate courts ... to create an appeal for an appellant,” nor is it “the duty of the appellate courts to supplement an appellant’s brief with legal authority or arguments not contained therein.”
First Charter Bank v. Am. Children’s Home, 203 N.C. App. 574, 580, 692 S.E.2d 457, 463 (2010) (quoting Viar v. N.C. Dep’t of Transp., 359 N.C. 400, 402, 610 S.E.2d 360, 361 (2005), and State v. Hill, 179 N.C. *403App. 1, 21, 632 S.E.2d 777, 789 (2006)).3 As a result, the only issue raised by Defendant’s challenge to the trial court’s order is the extent to which the trial court properly applied the applicable law to the uncontradicted evidence.
B. Date of Last Furnishing of Labor or Materials
As an initial matter, Defendants claim that the trial court erroneously granted summary judgment in favor of Plaintiff because Plaintiff failed to file its claim of lien in a timely manner. Defendants contend that Plaintiff was not entitled to treat the February 2010 letter as the date upon which services were last furnished to Richmond Hills for purposes of evaluating the timeliness of its claim of lien. We do not find Defendants’ argument persuasive.
N.C. Gen. Stat. § 44A-12(b) provides that “[c]laims of lien on real property may be filed at any time after the maturity of the obligation secured thereby but not later than 120 days after the last furnishing of labor or materials at the site of the improvement by the person claiming the lien.” The undisputed evidence contained in the present record establishes that Plaintiff entered into a contract with Richmond Hills on 10 August 2005. Mr. Irvin testified in his deposition that Plaintiff continued to perform work under that contract until 24 February 2010. More specifically, Mr. Irvin asserted in his affidavit that (1) Plaintiff’s “work often spans months or even years in a given development, sometimes with long gaps between service”; (2) the “parties in this case intended that such services would be provided for this development as a single seamless contract”; (3) the “services Ramey Kemp . . . provided to this developed,] in particular, were not piecemeal and subject to separate contracts or work orders, but con*404stituted a single [c]ontract,” with all work being “identified by the same Ramey Kemp Project Number (05128.0);” and (4) the “last work performed by Plaintiff on the property was at the specific request of Steve Saieed on behalf of Richmond Hills” and “included tasks that would have been contemplated, expected, and required in a project such as this one.” We conclude that this evidence, which is not contradicted by any other admissible evidence, clearly establishes that the last date upon which Plaintiff provided labor or materials to the project under its contract with Richmond Hills was 24 February 2010. As a result, given that Plaintiff filed a claim of lien applicable to the property on 30 March 2010, that filing was made well within the statutorily-specified 120 day period.
The presentation of the evidence outlined in the preceding paragraph shifted the burden of production to Defendants to adduce admissible evidence, as compared to mere speculation or conclusory assertions, demonstrating the existence of a genuine issue of material fact concerning the date upon which Plaintiff last provided services relating to the project under its contract with Richmond Hill. Defendants did not adduce such evidence. Instead, Defendants argue that the undisputed evidence establishes that the work upon which Plaintiff relies in support of its assertion that it last furnished work to Richmond Hills on 24 February 2010 resulted from “a separate contract between Ramey and Cape Fear Land Managers LLC” instead of having been performed under the initial contract between Plaintiff and Richmond Hills. After carefully reviewing the record, we conclude that this argument lacks both legal and evidentiary support given the facts disclosed in the present record.
As an initial matter, Mr. Irvin explicitly stated in his affidavit that the report in question was prepared at Mr. Saieed’s request under the original contract and that the preparation of such a report was consistent with the scope of the work to be performed by Plaintiff under the original contract. Defendants argue that the February 2010 report, which was prepared in order to facilitate a sale of the property on which the development was supposed to be completed, was prepared after the work contemplated under the original contract between Plaintiff and Richmond Hills had already been completed, with this assertion based on the fact that Richmond Hills had ceased work on the development due to the existence of financial problems prior to 24 February 2010. These arguments ignore Mr. Irvin’s testimony con*405cerning the scope of the work contemplated in the original contract, which would encompass a report of the type at issue here.4
In addition, Defendants direct our attention to the fact that the 25 February 2010 invoice was sent to Mr. Saieed do Cape Fear Land Managers LLC. However, the uncontradicted evidence contained in the present record indicates that, throughout the contract period, Plaintiff consistently sent invoices for the work performed under its contract with Richmond Hills to Mr. Saieed do Cape Fear Land Managers LLC. In other words, the invoice relating to the February 2010 report did not differ from Plaintiff’s earlier invoices, precluding us from inferring the existence of a new or “second” contract from the manner in which the invoice was addressed.5
Finally, Defendants stress that the work upon which Plaintiff relies to establish a date of last furnishing was performed more than a year after the last prior occasion on which Plaintiff had performed work for Richmond Hill. However, Mr. Irvin stated in his affidavit that *406Plaintiff’s “work often spans months or even years in a given development, sometimes with long gaps between service, given that such projects are often temporarily suspended and delayed by various events.” Defendant did not adduce any evidence that contradicted this assertion. As a result, for the reasons set forth above, we conclude that Defendants’ “two contract” theory, with which our dissenting colleague agrees, lacks adequate evidentiary support.
In their brief, Defendants place substantial reliance on the Supreme Court’s decision in Priddy v. Lumber Co., 258 N.C. 653, 129 S.E.2d 256 (1963). In Priddy, the defendant supplied materials required for the construction of a residence. After the completion of the necessary construction work, the defendant twice made unnecessary trivial purchases for the express purpose of extending the period of time within which a claim of lien might lawfully be filed. In holding that these purchases did not suffice to extend the time within which a claim of lien could properly be filed, the Supreme Court stated that:
“[T]he time for filing a claim in a mechanic’s lien proceeding is computed from the date when the last item of work labor or materials is done, performed or fumished[.] . . . But the work performed and materials furnished must be required by the contract, and whatever is done must be done in good faith for the purpose of fully performing the obligations of such contract, and not for the mere purpose of extending the time for filing lien proceedings.”. . . Furthermore, . . . the work or materials at different times [must] be furnished under one continuous contract. Where the time allowed for filing a lien has begun to run, the claimant cannot thereafter extend the time within which the lien may be filed by doing or furnishing small additional items for that purpose.
Priddy, 258 N.C. at 656-57, 129 S.E.2d at 260 (quoting Beaman v. Hotel Corp., 202 N.C. 418, 422-23, 163 S.E. 117, 119 (1932) (other citations omitted). As a result, Priddy “enunciated the following criteria for determining when the materials were last furnished for purposes of filing a materialmens lien:
(i) the work performed and materials furnished must be required by the contract
(ii) . . . the work or materials at different times [must] be furnished under one continuous contract
*407(iii) whatever is done must be done in good faith for the purpose of fully performing the obligations of the contract, and not for the mere purpose of extending the time for filing lien proceedings and, finally
(iv) where the time allowed for filing has begun to run, the claimant cannot thereafter extend the time within which the lien may be filed by doing or furnishing small additional items for that purpose.
Blalock Electric Co. v. Grassy Creek Development Corp., 99 N.C. App. 440, 447, 393 S.E.2d 354, 358 (1990) (citing Priddy, 258 N.C. at 657, 129 S.E.2d at 260). In analyzing these factors and determining the manner in which this case should be resolved, we find it useful to compare the facts at issue in Blalock with those at issue in Priddy.
In Blalock, the plaintiff, an electrical contractor, performed a substantial amount of electrical work on two condominiums, for which it was paid. Subsequently, Plaintiff stopped working on the project because “defendant was without funds to proceed with construction.” Blalock, 99 N.C. App at 442, 393 S.E.2d at 355. Some months later, at the defendant’s request, the plaintiff performed additional work on the project. On appeal, the defendant argued, in reliance on Priddy, that “the [trial] court erred in finding that the labor and materials supplied by plaintiff . . . were not trivial in nature and were performed in furtherance of the original contractual obligation.” Blalock at 444, 393 S.E.2d at 356. In rejecting this argument, we held that the record supported a finding that the work was performed under the original contract and that “there [was] no indication that the work . . . was done for the purpose of extending the time for filing the lien.” Blalock at 447, 393 S.E.2d at 358.
The facts contained in the present record resemble those at issue in Blalock more closely than those at issue in Priddy. More specifically, Plaintiff’s evidentiary showing indicated that Mr. Saieed requested production of a report detailing the status of the driveway permitting process, which had been the principal issue addressed in the earlier work that Plaintiff performed for Richmond Hills. In addition, the undisputed record evidence tends to show that Mr. Saieed had served as Richmond Hill’s contact with Plaintiff throughout the history of the project and that the invoice associated with this report had the same project number as all of the earlier invoices that Plaintiff had sent to Richmond Hills stemming from work performed in furtherance of this project. As the Supreme Court noted in *408Beaman, “[w]here a service is performed or material furnished at the request of the owner, it will extend the time for claiming a lien or will revive an expired lien, as to a contract. . . substantially completed.” Beaman, 202 N.C. at 422, 129 S.E.2d at 119 (citation omitted). Finally, Defendants adduced no evidence that the report upon which Plaintiff relies stemmed from any sort of collusion or bad faith. As a result, none of Defendants’ challenges to the trial court’s decision predicated on the timeliness of Plaintiff’s lien claim have any merit.
C. Improvement of Land
Secondly, Defendants argue that the trial court erred by granting summary judgment in favor of Plaintiff on the grounds that the report prepared by Plaintiff in February 2010 “did not go toward making an improvement to the land as required by [N.C. Gen. Stat.] § 44A-8.” This argument lacks merit.
N.C. Gen. Stat. § 44A-8 provides, in pertinent part, that a lien claim may be filed by “[a]ny person who performs or furnishes labor or professional design or surveying services or furnishes materials or furnishes rental equipment pursuant to a contract, either express or implied, with the owner of real property for the making of an improvement thereon.” According to Defendants, the report that Plaintiff prepared in February 2010 in connection with the proposed development did not contribute to the making of an improvement on the real property and was, for that reason, insufficient to support the filing of a claim of lien. Defendant’s argument overlooks N.C. Gen. Stat. § 44A-7, which provides, in pertinent part, that:
Unless the context otherwise requires in this Article:
(1) “Improve” means to build, effect, alter, repair, or demolish any improvement upon, connected with, or on or beneath the surface of any real property, or to excavate, clear, grade, fill or landscape any real property, or to construct driveways and private roadways, . . . and shall also mean and include any design or other professional or skilled services furnished by architects, engineers, [or] land surveyors[.] .. .
(2) “Improvement” means all or any part of any building, ... alteration, demolition, excavation, clearing, grading, filling, or landscaping, including trees and shrubbery, driveways, and private roadways, on real property.
*409As we have already noted, Plaintiff contracted with Richmond Hill to “provide all services relating to design, engineering, planning, and permit acquisition for roadways and driveways for development of the real property owned by Richmond Hills[.]” Although Defendants do not deny that the work described in this portion of the contract between Plaintiff and Richmond Hills comes within the statutory definition of an “improvement” to real property, they argue that the specific task that Plaintiff performed on 24 February 2010 did not directly result and was not intended to result in any improvement to the real property upon which Richmond Hill’s project was to be developed. In advancing this argument, Defendants rely upon the same “second contract” theory which we have already found to be lacking in merit. As a result, we necessarily reject Defendants’ contention that the work performed by Plaintiff under its contract with Richmond Hill did not involve the making of an improvement to land.
III. Conclusion
Thus, for the reasons set forth above, we conclude that the trial court did not err by entering summary judgment in Plaintiff’s favor.6 As a result, the trial court’s order should be, and hereby is, affirmed.
AFFIRMED.
Judge STEELMAN concurs. Judge McGee dissents in separate opinion.. Although our dissenting colleague questions our recitation of information contained in an affidavit filed by one of Plaintiff’s officers in this statement of the facts on the grounds that the extent to which the present case involves two contracts, rather than a single contract, is disputed, we do not, for the reasons set forth in more detail below, believe that the number of contracts at issue in this case is, in fact, in genuine dispute given the uncontradicted record evidence.
. As a result of the fact that the record on appeal failed to establish that Defendants’ third party complaint against Mr. Saieed had been resolved, this Court filed an unpublished opinion on 18 September 2012 dismissing Defendants’ appeal as having *401been taken from an unappealable interlocutory order. Ramey Kemp & Assocs. v. Richmond Hills Residential Partners, LLC,_N.C. App_, 731 S.E.2d 863 (2012) (2012 N.C. App. LEXIS 1109). On 27 September 2012, Defendants filed a petition for the issuance of a writ of certiorari and a motion seeking leave to amend the record so as to include a copy of an order entering default judgment against Mr. Saieed. On 4 October 2012, we entered orders allowing Defendants’ amendment motion, withdrawing our previous opinion, instructing the Clerk of this Court not to certify that opinion, and denying Defendants’ certiorari petition as moot. Ramey Kemp & Assocs. v. Richmond Hills, _N.C. App_,_S.E.2d_(2012 N.C. App. LEXIS 1150) (unpublished).
. Our dissenting colleague argues, in essence, that there is a genuine issue of material fact concerning the contents of the original agreement between the parties and whether the present record shows the existence of one contract, rather than two. Although a genuine evidentiary dispute between the parties concerning the number of contracts between the various parties would, in fact, suffice to preclude summary judgment in favor of Plaintiff, there is no direct evidence that the February 2010 letter was written pursuant to a separate contract between Plaintiff and Cape Fear Land Managers, LLC, which appears to be a separate business in which Mr. Saieed was also involved, rather than the 2005 contract between Plaintiff and Richmond Hill. Instead, our dissenting colleague appears to take the position that one can infer from the undisputed evidentiary facts that Plaintiff’s invoices were issued pursuant to two contracts rather than one. As a result, we do not believe that the argument advanced by our dissenting colleague rests upon a contention that the record discloses the existence of genuine issues concerning disputed evidentiary facts and believe that our colleague’s argument rests, instead, upon inferences which our colleague thinks can appropriately be drawn from the undisputed evidentiary facts.
. In reaching a different conclusion, our dissenting colleague emphasizes the existence of evidence tending to show some uncertainty as to whether the parties ever entered into a written contract and the fact that the preparation of a report was not included in the description of the “basic” contours of the work that Plaintiff originally agreed to perform for Richmond Hills. However, the record contains no indication that there was a written agreement that differed in any way from the description of the scope of the contract described by Mr. Irvin or that Mr. Irvin lacked personal knowledge of the scope of the parties’ agreement. In addition, nothing in the evidence provided by Mr. Irvin tends to suggest that the overall scope of the work to be performed under the contract was limited to the achievement of the parties’ “basic” goals. Finally, the alleged limitations in Mr. Irvin’s knowledge to which our dissenting colleague alludes for the purpose of attempting to establish “potential contradictions]” in his testimony relate to the administration of the underlying contract rather than to the origin and scope of that agreement. As a result, we do not believe that any of these arguments support reversal of the trial court’s order.
. Our dissenting colleague emphasizes the absence of any mention of Richmond Hills in the address used in the cover letter associated with the invoice relating to the work involved in the preparation of the February 2010 letter and the fact that Cape Fear was shown as the applicant for the requested driveway permit on certain documents sent to the North Carolina Department of Transportation as further support for her contention that the record would support a finding that the February 2010 letter was sent pursuant to a second contract between Plaintiff and Cape Fear. However, given that all of the invoices that Plaintiff sent relating to services provided with respect to the property on which the development was to be constructed were identical; given that the invoice, rather than the cover letter, is the operative document for billing purposes; and given that the record is devoid of any evidence affirmatively tending to show the existence of a second contract between Plaintiff and Cape Fear relating to the February 2010 letter, we do not believe that the additional factors upon which our dissenting colleague relies provide any substantive basis for inferring that there were two, rather than one, contracts relating to the property in question.
. Our dissenting colleague suggests that there are genuine issues of material fact arising from questions about the credibility of and weight to be given to Mr. Irvin’s testimony. However, summary judgment is appropriate, even in favor of a party with the burden of proof, when “there are only latent doubts as to the affiant’s credibility,” when the non-moving party fails to present any evidentiary materials that create a direct factual conflict, when the non-moving party “fail[s] to point to specific areas of impeachment or contradiction,” and when the non-moving party fails to utilize the procedures available pursuant to N.C. Gen. Stat. § 1A-1, Rule 56(f). Kidd v. Earley, 289 N.C. 343, 370, 222 S.E.2d 392, 410 (1976). In view of the fact that our dissenting colleague has failed to point out any specific basis for challenging the credibility of or weight to be given to the evidence provided by Mr. Irvin other than the limitations upon the extent of Mr. Irvin’s knowledge and given that these limitation do not, for the reasons set forth earlier, provide any basis for questioning his knowledge of the scope of the work required under the 2005 contract, we do not believe that summary judgment should have been denied based on weight and credibility considerations.
