Opinion for the Court filed by Circuit Judge GINSBURG.
Capitol Sprinkler Inspection, Inc., the defendant in the district court, appeals the summary judgment entered for Guest Services, Inc. on Capitol’s third-party claims for negligence and breach of contract in connection with a burst pipe at a building managed by Guest. Guest argues we lack jurisdiction for want of a timely notice of appeal. We hold that we have jurisdiction of the appeal based upon Federal Rule of Appellate Procedure 4(a)(2) and affirm the district court in all respects.
I. Background
Gallaudet University hired Guest to manage the conference center building on its campus in Washington, D.C. Guest in *220 turn retained Capitol to service the fire sprinkler system in the conference center. One of Capitol’s contractual duties was “opening] condensation drains on drum drip connections and draining] low points during fall and winter inspection.”
In January 2003 two of Capitol’s inspectors came to the conference center, where they were met by someone who escorted them around the building. The record does not reveal whether their escort was an employee of Guest. While on site, the inspectors drained water from all but one of the drum drips; that one was in a locked room for which the escort was not carrying a key card. Later that month, a pipe fitting froze, burst, and discharged water, which would not have happened if Capitol’s inspectors had drained the drum drip.
Gallaudet filed a claim for the resulting damage with its property insurer, St. Paul Mercury Insurance. St. Paul, as Gallaudet’s subrogee, then filed suit against Capitol for both negligence and breach of contract. Capitol in turn filed a third-party complaint against Guest, seeking contribution or indemnity, again based upon both negligence and breach of contract.
All parties filed dispositive motions. St. Paul moved for partial summary judgment on its contract claim against Capitol, which cross-moved for summary judgment against St. Paul on both claims. Capitol and Guest filed cross-motions for summary judgment on the third-party claims. All the motions drew responses and replies except that Guest did not timely respond to Capitol’s motion for summary judgment. The district court denied Guest’s motion to file a late response but nonetheless deemed Capitol’s motion for summary judgment opposed because Guest, in the course of supporting its own motion, had briefed the relevant issues.
The district court denied Capitol’s motion for summary judgment against Guest and its motion to strike Guest’s reply in support of its motion for summary judgment. Because St. Paul had argued that Capitol could not prevail without expert testimony to explain the applicable standard of care in tort and the contractual duty Guest owed to Capitol but “the parties [had] devote[d] only scant attention to” the subject, the court was “unwilling to rule on [that] dispositive issue”; instead the court held all other motions in abeyance pending supplemental briefing on the need for expert testimony. On June 15, 2009 the district court, having determined Capitol could not prove its claims or defenses without expert testimony to explain Guest’s duty, entered an order granting Guest’s and St. Paul’s motions respectively for summary and for partial summary judgment and stating “Guest Services is dismissed from further proceedings in this case.” St. Paul’s tort claim against Capitol, which had not been a subject of St. Paul’s dispositive motion, alone remained pending.
Capitol then filed a motion pursuant to Federal Rule of Civil Procedure 54(b) asking the district court to certify an interlocutory appeal or, in the alternative, for reconsideration of its June 15 order granting summary judgment to Guest. The district court denied Capitol’s motion, holding an immediate appeal would be inappropriate because the third-party claims overlapped with St. Paul’s claims against Capitol and rejecting Capitol’s arguments in the alternative for reconsideration.
On October 16 Capitol and St. Paul informed the court they had “settled all claims between them,” would “finalize a settlement agreement” within 30 days, and would thereafter file a joint stipulation of dismissal. Later that same day Capitol filed a notice of appeal with respect to its *221 claims against Guest. Later still that day, the district court entered an order dismissing the case without prejudice based upon the impending settlement and stating the case would stand dismissed with prejudice as of October 26 unless counsel moved to extend the date or to reopen the case. On October 23 St. Paul and Capitol filed their joint stipulation of dismissal. The order dismissing the case having become final on October 26, this appeal by Capitol proceeded without further action by the district court and without Capitol having filed a notice of appeal from the final judgment.
II. Analysis
On appeal, Capitol challenges the district court’s order denying its and granting Guest’s motion for summary judgment, and the orders denying its motions (1) to supplement its expert disclosures, (2) to strike Guest’s reply, and (3) for reconsideration or for an appealable judgment under Rule 54(b). Guest defends each of those orders but first argues this court lacks appellate jurisdiction. We begin, of course, with our jurisdiction.
Yousuf v. Samantar,
A. Appellate Jurisdiction
To vest this court with appellate jurisdiction under 28 U.S.C. § 1291, the appellant must file a timely notice of appeal from a final, appealable judgment of the district court.
See Budinich v. Becton Dickinson & Co.,
In the present case, it is undisputed Capitol’s only notice of appeal was filed prematurely, that is, before the district court had entered a final, appealable judgment. When Capitol filed the notice of appeal on October 16, the district court had granted summary judgment in favor of Guest on Capitol’s third-party claims — the only claims Capitol sought to appeal — but had neither disposed of all St. Paul’s claims nor entered a partial final judgment pursuant to Rule 54(b). Indeed, the court had expressly denied Capitol’s motion for a Rule 54(b) judgment. St. Paul and Capitol had notified the court earlier that day of their agreement to settle the remaining claims, but their letter informed the court they would file a stipulation of dismissal in the future, making it clear the proceedings in the district court were still ongoing as of October 16.
A premature notice of appeal “filed after the court announces a decision or order [ ] but before the entry of judgment or order” can be saved by Federal Rule of Appellate Procedure 4(a)(2), which provides such a notice is to be “treated as filed on the date of and after the entry” of a judgment or order. Still, the Supreme Court has held “Rule 4(a)(2) permits a notice of appeal from a nonfinal decision to operate as a notice of appeal from the final judgment only when a district court announces a decision that
would be
appealable if immediately followed by the entry of judgment,” because in such a situation a litigant could reasonably believe the order was appeal-able.
FirsTier Mortg. Co. v. Investors Mortg. Ins. Co.,
In
Outlaw v. Airtech Air Conditioning & Heating, Inc.,
this court held Rule 4(a)(2) applies to a ruling disposing of fewer than all parties or all claims no differently than to a ruling disposing of an entire case.
In this case, Capitol would have been able to appeal if the district court had entered a Rule 54(b) judgment after it granted summary judgment for Guest, and it is undisputed the district court did eventually enter a final judgment disposing of the entire case. The relevant question here is whether anything that happened before Capitol filed its notice of appeal warrants a different result than in Outlaw.
Guest first argues Rule 4(a)(2) does not apply because it applies only to decisions that have been “announced from the bench” whereas here, unlike in Outlaw, all decisions were written. That factual difference is of no moment, however; indeed, the relevant ruling in Outlaw was a written order granting summary judgment as to fewer than all parties. See id. at 159.
A more promising distinction between this case and
Outlaw
might be that here the district court had denied Capitol’s Rule 54(b) motion and request to certify an interlocutory appeal against Guest, arguably indicating thereby that the possibility of an appealable judgment was foreclosed. The difference is not significant, however; the analysis in
Outlaw
turned upon whether a “hypothetical” judgment under Rule 54(b) would have rendered the case appealable,
id.
at 162 (“[t]he analysis was hypothetical in
FirsTier
itself’). We did not consider whether there was “no just reason for delay” or whether the district court would have abused its discretion by entering a Rule 54(b) judgment, as we would have done were we reviewing an actual rather than a hypothetical judgment.

B. Capitol’s Motion for Summary Judgment
The district court denied Capitol’s motion for summary judgment because it found there were
genuine issues of material fact as to whether Capitol Sprinkler was escorted by a Guest Services employee ..., whether and to what extent Guest Services operated as an agent of Gallaudet, and whether and to what extent [the relevant standard of the National Fire Protection Association was] incorporated into the Inspection Agreement between Capitol Sprinkler and Guest Services.
St. Paul Mercury Ins. Co. v. Capitol Sprinkler Inspection, Inc.,
Capitol argues the court should have granted its motion for summary judgment because Guest did not oppose the motion, as required by Local Civil Rule 7(h) and by the district court’s scheduling order. As Guest correctly points out, however, Rule 7(h) provides the district court “may assume” facts not denied in an opposition have been admitted, thus leaving the matter to the district court’s discretion, and “this court has long recognized that the district court does not abuse its discretion by declining to invoke the requirements of the local rule in ruling on a motion for summary judgment.”
Burke v. Gould,
Capitol also argues the district court erred by denying the summary judgment motion on its merits, a decision we review de novo.
McFadden v. Ballard Spahr Andrews & Ingersoll, LLP,
As to the merits, Capitol’s first but cursory argument is that the district court erred by weighing the evidence. This argument is beside the point because our review is de novo.
See Wiley v. Glassman,
Capitol also fails to establish it is entitled to judgment as a matter of law because Guest was responsible for the acts and omissions of the escort. One of Capitol’s inspectors testified in his deposition the escort was “assigned” to provide access to certain rooms but did not say by whom he was assigned. There was an affidavit before the district court from Capitol’s other inspector conclusorily stating the escort was “an agent of Guest Services, Inc.” Even assuming — as did the district court,
see
Next, Capitol argues that, unlike the district court, we should consider Guest’s conduct before and on the day the pipe burst, “not the least of which was [its] failure to timely terminate water flow.” Notwithstanding its use of the phrase “the least,” Capitol identifies no other conduct the court should have considered. As Guest argues, the alacrity with which it staunched the flow of water is relevant only to the measure of damages, which is not at issue in this appeal.
Finally, Capitol’s argument that it could have proven its case using St. Paul’s expert or its own so-called “hybrid” faetcum-expert witnesses, is off the mark because, again as Guest notes, the testimony of those witnesses would not bear upon the relationship between Guest and the escort. Therefore we affirm the order of the district court denying Capitol’s motion for summary judgment.
C. Guest’s Motion for Summary Judgment
Capitol next challenges the order granting summary judgment for Guest. The district court granted that motion because Capitol had failed to present the expert testimony required under District of Columbia law to prevail upon its claims, which sound in tort and contract.
St. Paul Mercury Ins. Co. v. Capitol Sprinkler Inspection, Inc.,
First, Capitol argues summary judgment was inappropriate because the district court had concluded there were genuine issues of material fact as to whether the escort worked for Guest, whether Guest was Gallaudet’s agent, and whether the National Fire Protection Association (NFPA) standards were incorporated into the contract between Guest and Capitol. Guest responds that, although disputed, none of these three issues is material because Capitol’s failure to disclose, pursuant to Rule 26, expert testimony concerning the standard of care or contractual duty independently dooms its claims respectively for negligence and for breach of contract. Both claims are premised upon applying the NFPA standard for building owners’ dealings with inspectors. Under that standard, a building owner must “provide ready accessibility to components of water-based fire protection sys *225 terns that require inspection, testing, or maintenance.”
As the district court noted,
Capitol’s fallback argument is that expert testimony was not required in any event: “If the court had provided guidance on the statute’s interpretation, a jury could have come to a conclusion regarding whether Guest provided Capitol with ‘ready accessibility,’ ” all the more so because the disputed issue — whether the drum drip was readily accessible if the inspectors had to wait five to ten minutes to gain access — is factually straightforward. The controlling case law is less forgiving than Capitol assumes; in the District of Columbia an expert witness is required to establish the standard of care or the contractual duty,
see Sherman v. Adoption Ctr. of Washington, Inc.,
In the light of these precedents, Capitol clearly was required to present expert testimony on what it means to have “ready accessibility” to a drum drip. Although accessibility of a drum drip is not a complex technical issue and might appear to be within a jury’s understanding, id. at 845, the specific requirements of a set of rules for fire protection, like the specific requirements for safely lighting a subway station, are not a matter of common knowledge. Because Capitol did not offer expert testimony to explain the NFPA standard, summary judgment for Guest was appropriate.
D. Rulings Reviewed for Abuse of Discretion
As noted before, Capitol also challenges the orders of the district court denying its motions (1) to supplement expert disclosure, (2) to strike a reply, and (3) for judgment under Rule 54(b) or for reconsideration. We review all three rulings for abuse of discretion.
See Washburn v. Lavoie,
1. Motion to Supplement Expert Disclosure
Capitol argues the district court erred by denying its motion to file a supplement to its expert disclosures after the deadline for filing had passed and discovery had closed. The court denied the motion because it concluded Capitol had not shown “good cause” for its tardiness, as required by Federal Rule of Civil Procedure 16(b)(4).
St. Paul Mercury Ins. Co. v. Capitol Sprinkler Inspection, Inc.,
Civ. A. No. 05-2115,
As Guest suggests, “[t]he good cause standard requires the ‘party seeking relief to show that the deadlines cannot reasonably be met despite [its] diligence.’ ” S
& W Enters., LLC v. SouthTrust Bank,
2. Motion to Strike Guest’s Reply
Capitol next argues the district court erred by denying its motion to strike the reply Guest filed in support of its motion for summary judgment; the motion to strike was based upon Guest’s supposedly late introduction of arguments and facts. The district court rejected this argument and denied the motion to strike because the reply brief and an attached affidavit did no more than bolster Guest’s opening arguments.
*
Accordingly, we hold the district court did not abuse its discretion by denying the motion.
Cf. Stabilisierungsfonds Fur Wein v. Kaiser Stuhl Wine Distrib.,
3. Motion for Interlocutory Appeal or Reconsideration
Finally, Capitol argues the district court erred by denying its motion for a Rule 54(b) judgment, which would have enabled Capitol to appeal at once the order granting summary judgment to Guest, or in the alternative, for reconsideration of the same
*227
order. The interlocutory appeal issue is now moot because a final judgment has been entered and the case has been presented to this court on appeal. Thus, Capitol has already obtained the relief it sought, that is, the right to appeal the order.
See I.A.M. Nat’l Pension Fund Benefit Plan A v. Cooper Indus., Inc.,
The district court addressed Capitol’s request for reconsideration pursuant to Rule 54(b), which not only authorizes the court to enter a partial final judgment but also recognizes its inherent power to reconsider an interlocutory order “as justice requires.”
See Greene v. Union Mut. Life Ins. Co. of Am.,
The district court understandably determined justice did not require reconsidering its order, for Capitol raised no arguments for reconsideration the court had not already rejected on the merits except its argument that the court had improperly weighed testimony. Similarly, on appeal, Capitol merely repeats its arguments concerning summary judgment. These arguments are without merit for reasons already stated; a fortiori, the district court did not abuse its discretion by denying Capitol’s motion for reconsideration.
III. Conclusion
For the foregoing reasons, this court has appellate jurisdiction of the instant matter pursuant to Rule 4(a)(2), and the judgment of the district court is in all respects
Affirmed.
Notes
We note also the allegedly new facts and arguments to which Capitol points were raised in direct reply to Capitol’s submission of what the district court later determined was a “sham affidavit.”
