                  Appeal from the United States District Court
                       for the Western District of Texas
                             USDC No. 1:19-cv-24

   Before Davis, Haynes, and Oldham, Circuit Judges.
   Andrew S. Oldham, Circuit Judge:
          This appeal arises from a highway construction project gone wrong.
   The question presented is whether the issuer of a commercial general liability
   policy, Arch Insurance Company, has a duty to defend the project’s general
   contractor. The district court answered no. We disagree and reverse.
                                         I.
                                        A.
          SH 130 Concession Company, LLC (“Developer”) holds a
   concession to design and construct a 41-mile stretch of highway (“Project”)
Case: 20-50966      Document: 00516131058           Page: 2     Date Filed: 12/14/2021

                                     No. 20-50966

   running from Mustang Ridge to the I-10 connector near Seguin, Texas. The
   Developer hired Central Texas Highway Constructors, LLC (“CTHC”) as
   the Project’s general contractor. CTHC in turn hired Archer Western
   Contractors, Ltd. (“Archer Western”), among others, as a subcontractor. As
   most relevant here, Archer Western agreed to construct certain drainage
   systems for the Project.
          Archer Western obtained annual commercial general liability
   (“CGL”) policies from Arch Insurance Company (“Arch”) that were
   effective from June 1, 2009, through June 1, 2018 (collectively, “Policy”). In
   the Policy, Arch assumed both a duty to indemnify and a duty to defend. As
   to the duty to indemnify, the Policy provides: “[Arch] will pay those sums
   that the insured becomes legally obligated to pay as damages because of
   ‘bodily injury’ or ‘property damage’ to which this insurance applies.” As to
   the duty to defend, the Policy states: “[Arch] will have the right and duty to
   defend the insured against any ‘suit’ seeking those damages. However,
   [Arch] will have no duty to defend the insured against any ‘suit’ seeking
   damages for ‘bodily injury’ or ‘property damage’ to which this insurance
   does not apply.” This case involves only Arch’s duty to defend.
          The subcontract required Archer Western to name CTHC as an
   “additional insured” on its Policy. Archer Western did so with two
   endorsements. First, the “Completed Operations Endorsement” extends
   coverage to the “additional insured [CTHC] . . . with respect to liability for
   ‘bodily injury’ or ‘property damage’ caused, in whole or in part by, ‘your
   work’ [Archer Western’s] at the location designated . . . performed for that
   additional   insured [CTHC].” Second,             the “Ongoing       Operations
   Endorsement” extends coverage under the Policy to the “additional insured
   [CTHC] . . . with respect to liability for ‘bodily injury’, ‘property damage’
   or ‘personal and advertising injury’ caused, in whole or in part, by . . . [Archer
   Western’s] acts or omissions . . . in the performance of [its] ongoing

                                     No. 20-50966

   operations for the additional insured [CTHC].” In sum, these two
   endorsements extend coverage under the Policy to CTHC for work Archer
   Western performed.
          Work on the Project wrapped up in October 2012. On September 6,
   2017, the Developer sent CTHC a notice of claim. About six weeks later, on
   October 20, 2017, the Developer requested arbitration against CTHC. The
   Developer alleged that CTHC and two other named contractors “fell far
   short of meeting their contractual obligations.” Portions of the Project had
   “beg[un] to crack and heave before the road even opened to the public, and
   these pavement failures . . . indicated that a significant underlying error in
   design and construction was causing the pavement to fail.” The Developer
   also alleged that an investigation revealed that “CTHC improperly designed
   and constructed the pavement subgrade in such a way that it would inevitably
   expand” and caused the alleged deficiencies. It sought “to recover the full
   cost of remediating the project-wide defect in th[e] arbitration, along with
   other damages.” Throughout this opinion, we’ll refer to this arbitration
   proceeding (Developer v. CTHC) as the “underlying litigation” or the
   “underlying arbitration.”
          The Developer’s request for arbitration also incorporated its notice of
   claim against CTHC. The notice of claim, in turn, referenced several bridge
   inspection reports detailing alleged defects in portions of the Project. As most
   relevant here, the bridge inspection reports found that at least one bridge
   abutment “appear[ed] to have rotated . . . due to moderate erosion caused by
   [a] deck drainage outlet pipe between girder 1 and 2[,] . . . which ha[d] created
   a [three-foot-deep] void.” The reports also noted that another bridge
   abutment had experienced “moderate erosion due to [a] deck drainage
   outlet.”

                                     No. 20-50966

          The Developer later filed a more detailed statement of claim in the
   underlying arbitration. In it, the Developer alleged three categories of defects
   in the Project: “(1) pavement defects, (2) slope defects, and (3) bridge
   defects.” As to category (1), the Developer alleged that “the cracking and
   heaving in the roadway was the result of differential movement related to
   subgrade heave and sulfate reactions,” which itself was “the direct result of
   CTHC’s failure to design and construct the [Project] subgrade and pavement
   structure in accordance with its contractual obligations.” As to category (2),
   the Developer alleged that CTHC’s design choices had caused slopes
   adjacent to the highway to fail. And as to category (3), the Developer alleged
   that CTHC “failed to properly account for the soils at the bridges, and in
   doing so, created problems such that multiple bridges—the most long-lived
   assets of a road’s infrastructure—are exhibiting early signs of aging and
   premature failure.” In sum, the Developer’s claims in the underlying
   arbitration alleged that poor drainage caused physical damage to parts of the
   Project.
                                         B.
          Given the Developer’s claims in the underlying arbitration against
   CTHC,      CTHC’s      insurer—Zurich      American        Insurance   Company
   (“Zurich”)—invoked Arch’s duty to defend CTHC. Arch refused. So
   Zurich sued. It sought a declaration that Arch owes CTHC a duty to defend,
   as well as reimbursement for defense costs already incurred. The parties
   eventually cross-moved for summary judgment, which the district court
   referred to a magistrate judge.
          The magistrate judge issued a report and recommendation that Arch’s
   motion for summary judgment be granted because none of the Developer’s
   claims potentially fell within the Policy’s coverage. In reaching that
   recommendation, the magistrate judge determined that some of the

                                          4
Case: 20-50966        Document: 00516131058        Page: 5    Date Filed: 12/14/2021

                                    No. 20-50966

   Developer’s allegations concerned damage to Archer Western’s own work,
   which was expressly excluded from the Policy’s coverage; that the Developer
   never alleged Archer Western caused the complained-of defects; and that
   some of the Developer’s allegations could only hypothetically implicate
   Archer Western’s work.
          The district court adopted that recommendation and entered partial
   final judgment in favor of Arch under Federal Rule of Civil Procedure 54(b).
   Zurich timely appealed. We have jurisdiction under 28 U.S.C. § 1291. It’s
   undisputed that we must apply Illinois law. And our review is de novo. See
   Landry’s, Inc. v. Ins. Co. of the State of Pa., 4 F.4th 366, 368 (5th Cir. 2021)
   (applying de novo review to summary judgment decision); Central Ill. Light
   Co. v. Home Ins. Co., 821 N.E.2d 206, 213 (Ill. 2004) (holding that, under
   Illinois law, interpretation of an insurance policy is a question of law that we
   review de novo).
                                         II.
                                         A.
          It’s undisputed that if either of the Policy’s two endorsements
   potentially applies, then Arch (the issuer of the Policy) owes a duty to defend
   CTHC (the additional insured in the endorsements) in the underlying
   arbitration (Developer v. CTHC). It’s also undisputed that the applicability
   vel non of the endorsements turns on whether Archer Western (the primary
   insured) performed work that could trigger its Policy with Arch. Complicated
   as this might seem, the web of the insurance contracts creates a relatively
   straightforward question: Do the Developer’s claims against CTHC in the
   underlying arbitration potentially implicate Archer Western’s drainage-
   system work, such that Archer Western’s insurer (Arch) owes a duty to
   defend the additional insured (CTHC)? The answer is yes.

          “To determine whether an insurer has a duty to defend its insured
   from a lawsuit, a court must compare the facts alleged in the underlying
   complaint to the relevant provisions of the insurance policy.” Valley Forge
   Ins. Co. v. Swiderski Elecs., Inc., 860 N.E.2d 307, 314 (Ill. 2006). “If the
   [relevant documents] allege facts within or potentially within policy
   coverage, the insurer is obliged to defend its insured even if the allegations
   are groundless, false, or fraudulent.” Northbrook Prop. & Cas. Co. v. Transp.
   Joint Agreement, 741 N.E.2d 253, 254 (Ill. 2000); see also Valley Forge, 860
   N.E.2d at 314–15. The alleged facts need only be “potentially within” the
   policy’s coverage. Am. States Ins. Co. v. Koloms, 687 N.E.2d 72, 75 (Ill. 1997)
   (emphasis added); see also, e.g., Valley Forge, 860 N.E.2d at 314–15. For this
   reason, the “threshold that [the relevant documents] must satisfy to present
   a claim of potential coverage is low.” LaGrange Mem’l Hosp. v. St. Paul Ins.
   Co., 740 N.E.2d 21, 27 (Ill. App. Ct. 2000); see also, e.g., Bituminous Cas.
   Corp. v. Gust K. Newberg Constr. Co., 578 N.E.2d 1003, 1006 (Ill. App. Ct.
   1991) (Threshold is “minimal.”); Del Monte Fresh Produce N.A., Inc. v.
   Transp. Ins. Co., 500 F.3d 640, 643 (7th Cir. 2007) (Illinois law) (“In a duty-
   to-defend action, we begin with the deck stacked in favor of the insured.”).
          In comparing the Policy’s language to the allegations in the underlying
   litigation, we must “liberally construe[]” the allegations “in favor of the
   insured.” Valley Forge, 860 N.E.2d at 314; see also, e.g., Diamond State Ins.
   Co. v. Chester-Jensen Co., 611 N.E.2d 1083, 1087 (Ill. App. Ct. 1993) (“The
   complaint must be liberally construed and all doubts resolved in favor of
   coverage for the insured.”); Westfield Ins. Co. v. W. Van Buren, LLC, 59
   N.E.3d 877, 882 (Ill. App. Ct. 2016) (same); Ill. Tool Works Inc. v. Travelers
   Cas. & Sur. Co., 26 N.E.3d 421, 428 (Ill. App. Ct. 2015) (describing the “well-
   settled principle followed by Illinois courts: that vague, ambiguous
   allegations against an insured should be resolved in favor of finding a duty to
   defend”). We also must construe any ambiguity in the Policy “strictly against

   1011, 1017 (Ill. 2010) (quoting Koloms, 687 N.E.2d at 75). Put together, “[a]n
   insurer may not justifiably refuse to defend an action against its insured
   unless it is clear from the face of the [relevant documents] that the allegations
   [in the underlying litigation] fail to state facts which bring the case within, or
   potentially within, the policy’s coverage.” Northbrook, 741 N.E.2d at 254
   (emphases added); see also Valley Forge, 860 N.E.2d at 315.
                                                B.
           We begin, as always, with the relevant text. The Policy provides in
   pertinent part:
           b. This insurance applies to “bodily injury” or “property
           damage” only if:
                    (1) The “bodily injury” or “property damage” is
                    caused by an “occurrence” that takes place in the
                    “coverage territory”; and
                    (2) The “bodily injury” and “property damage” first
                    takes place during the policy period regardless of when
                    the “occurrence” giving rise to “bodily injury” or
                    “property damage” takes place.
   The Policy defines “occurrence” as “an accident, including continuous or
   repeated exposure to substantially the same general harmful conditions,
   which results in ‘bodily injury’ or ‘property damage’, neither expected nor
   intended from the standpoint of any insured.” 1 It defines “property damage”
   as:

           1
             Before June 1, 2010, the Policy defined “occurrence” as “an accident, including
   continuous or repeated exposure to substantially the same general harmful conditions.”
   But in these circumstances, the definitions are materially identical for two reasons. First,
   the Policy before the June 1, 2010 clarification had an exclusion, stating that the “insurance
   does not apply to . . . ‘[b]odily injury’ or ‘property damage’ expected or intended from the

                                                 7
Case: 20-50966         Document: 00516131058               Page: 8      Date Filed: 12/14/2021

                                          No. 20-50966

           a. Physical injury to tangible property, including all resulting
           loss of use of that property. All such loss of use shall be deemed
           to occur at the time of the physical injury that caused it; or
           b. Loss of use of tangible property that is not physically injured.
           All such loss of use shall be deemed to occur at the time of the
           “occurrence” that caused it.
   Put together, the Policy applies where Archer Western (1) causes an accident
   (2) that causes property damage (3) during the policy period.
           With the Policy’s three requirements so understood, we turn next to
   the allegations in the underlying litigation. Here, the underlying litigation is
   the Developer’s arbitration against CTHC. The parties agree that we may
   consider the allegations in the Developer’s request for arbitration, its notice
   of claim, and its statement of claim, including other documents incorporated
   by reference. The Developer’s allegations in those documents potentially
   satisfy all three of the Policy’s aforementioned requirements. That’s because
   the Developer is complaining that drainage work performed by Archer
   Western damaged the Project—thus potentially triggering Archer Western’s
   Policy and Arch’s duty to defend under that Policy.

   standpoint of the insured.” Second, we must give the definition its “plain, ordinary, and
   popular meaning.” Traveler’s Ins. Co. v. Eljer Mfg., Inc., 757 N.E.2d 481, 494 (Ill. 2001)
   (quotation omitted); Antonin Scalia & Bryan A. Garner, Reading Law:
   The Interpretation of Legal Texts 228 (2012) (“Sometimes a definition itself
   contains a term that is not clear. When that is the case, the usual criteria of interpretation
   . . . are brought to bear.”). And according to Illinois courts, the ordinary meaning of
   “accident” in the context of an insurance policy indicates that the “result” was “neither
   expected nor intended.” Pekin Ins. Co. v. McKeown Classic Homes, Inc., 161 N.E.3d 1059,
   1070 (Ill. App. Ct. 2020); see also ibid. (“The use of the word ‘occurrence’ in insurance
   policies broadens coverage and eliminates the need to find an exact cause of damages as
   long as they are neither intended nor expected by the insured.” (quotation omitted)); W.
   Bend Mut. Ins. Co. v. People, 929 N.E.2d 606, 614 (Ill. App. Ct. 2010) (“The policies specify
   that an occurrence is an accident. The natural and ordinary consequences of an act do not
   constitute an accident.”).

                                                 8
Case: 20-50966      Document: 00516131058           Page: 9     Date Filed: 12/14/2021

                                     No. 20-50966

          First, the accident. The Developer alleged that work on the highway’s
   drainage system led to unintentional and unexpected damages to the Project.
   Archer Western, of course, performed work on that drainage system. And
   there’s no contention that Archer Western intentionally constructed that
   system to damage the Project. Nor is there any contention that anyone
   expected Archer Western’s drainage system to damage the Project. So the
   allegations potentially meet the Policy’s definition of an “occurrence,” i.e.,
   an “accident.”
          Second, the property damage. The Developer alleged that the
   improperly installed drainage systems caused “soil erosion” that in turn
   caused, among other things, “abutment movements,” “shear[ed] . . . bearing
   pads,” and “crack[ed] . . . riprap.” Specifically, in the request for arbitration,
   the Developer incorporated by reference several bridge inspection reports
   that detailed alleged defects in the Project. Those reports alleged that
   abutments adjacent to SH 130 had “rotated towards [the highway] due to
   moderate erosion caused by [a] deck drainage outlet pipe.” And another
   abutment “ha[d] moderate erosion due to [a] deck drainage outlet.” The
   statement of claim further alleged “poor drainage” was the cause of various
   injuries:
          [A]butment movements caused by differential soil movement
          . . . as well as soil erosion caused by poor drainage, have closed
          the expansion joints, sheared the bearing pads, caused heaving
          of the approach slabs, brought several of the girders into
          contact with the backwall, displaced the riprap, and resulted in
          cracks in the riprap, the backwalls and the wingwalls.
          Soil, bearing pads, and riprap are “tangible property.” Erosion,
   piercing, and cracking are “physical injuries.” See Traveler’s Ins. Co. v. Eljer
   Mfg., Inc., 757 N.E.2d 481, 502 (Ill. 2001) (“[U]nder its plain and ordinary
   meaning, the term ‘physical injury’ unambiguously connotes damage to

                                           9
Case: 20-50966        Document: 00516131058              Page: 10       Date Filed: 12/14/2021

                                         No. 20-50966

   tangible property causing an alteration in appearance, shape, color or in other
   material dimension.”). And the allegations use the phrase “caused by”—the
   same phrase used in the applicable Policy provisions. 2 Thus, the Developer’s
   allegations in the underlying litigation potentially satisfy the Policy’s
   definition of “property damage.”
           Third, timing. Under the Policy, “property damage” “is deemed to
   first take place at the earliest of when” the damage “began” or “first
   manifest[ed].” The Policy also makes clear that “all resulting loss of use of
   that property” is “deemed to occur at the time of the physical injury that
   caused it.” All agree that the Policy covered the time period between June 1,
   2009, and June 1, 2018. The Developer alleged that some of the defects “first
   manifest[ed]” in 2014. That’s well within the Policy’s effective period. Plus,
   all the allegations in the notice of claim and request for arbitration were sent
   in 2017—still before the coverage period ended.
           There’s still more. The Developer also alleged that the defects are
   “rooted in the same problem” as earlier damage and are “due to” issues
   “present” earlier. So not only did the Developer allege that the physical
   injury manifested during the coverage period, but it also alleged that later
   injuries trace to when the work was performed. And there’s no dispute that
   Archer Western performed its actions during that coverage period. Because
   the Policy specifies that “all resulting loss of use of that property” is
   “deemed to occur at the time of the physical injury that caused it,” any

             It’s true that the Developer’s allegations in the underlying litigation sometimes
   also use the phrase “due to.” But given that we must liberally read the allegations (and the
   Policy) in the insured’s favor and that the allegations need only “potentially” fall within
   coverage, we see no material difference between “caused by” and “due to.” See, e.g.,
   Valley Forge, 860 N.E.2d at 314–15; Wilson, 930 N.E.2d at 1017; Koloms, 687 N.E.2d at 75.

           Arch makes two counterarguments. Both fail.
                                                  1.
           Arch argues that the Developer does not expressly state a claim
   against Archer Western in the underlying arbitration (Developer v. CTHC).
   Indeed, the Developer’s claims in that underlying arbitration do not even
   mention Archer Western by name. Thus, Arch contends, the Developer’s
   claims against Archer Western are at most implied by its claims against
   CTHC and thus should not trigger Arch’s duty to defend under the Policy.
           We disagree. That’s for at least three reasons.
           First, the Developer’s allegations implicating Archer Western are
   specific enough. The Developer alleged that Archer Western’s work
   (installation of the drainage system) was defective and caused erosion that in
   turn caused damage to other property (e.g., bearing pads and riprap). That is
   an express allegation, not an implied one.
           In these circumstances, it doesn’t matter that the allegations failed to
   expressly name Archer Western while naming other subcontractors. Arch
   hasn’t pointed to anything in the allegations that suggests the named
   subcontractors were exhaustive. See Am. Econ. Ins. Co. v. Holabird & Root,
   886 N.E.2d 1166, 1179 (Ill. App. Ct. 2008) (“The underlying complaint does

           3
             Arch insists that Zurich forfeited any arguments on timing for failing to argue it
   in its opening brief. Not so. “We do not require a litigant to anticipatorily rebut all potential
   arguments his adversary may raise. Failing to do so is not a forfeiture.” Hoyt v. Lane Constr.
   Corp., 927 F.3d 287, 296 n.2 (5th Cir. 2019); see also United States v. Ramirez, 557 F.3d 200,
   203 (5th Cir. 2009).

                                                  11
Case: 20-50966     Document: 00516131058            Page: 12    Date Filed: 12/14/2021

                                     No. 20-50966

   not allege that these were the only entities involved in the construction of the
   City’s space and the third-party complaint confirms that there was at least
   one other subcontractor on the site.”). The allegations therefore “impl[y]
   . . . that other parties may have been involved in the project.” Id. at 1180.
   That’s especially true given that we must read the allegations in the insured’s
   favor. So in this respect, the allegations are specific enough.
          It also doesn’t matter that the Developer’s primary focus in the
   arbitration documents is on the work done by CTHC rather than Archer
   Western. That’s because the “duty to defend extends to cases where the
   complaint alleges several causes of action or theories of recovery against the
   insured, one of which is within the coverage of a policy while the others may
   not be.” Md. Cas. Co. v. Peppers, 355 N.E.2d 24, 28 (Ill. 1976); see also Gen.
   Agents Ins. Co. of Am. v. Midwest Sporting Goods Co., 828 N.E.2d 1092, 1098
   (Ill. 2005). That’s so even though “the insurer may become obligated to
   defend against causes of action and theories of recovery that the policy does
   not actually cover.” Stoneridge Dev. Co. v. Essex Ins. Co., 888 N.E.2d 633, 644
   (Ill. App. Ct. 2008). The bottom line is that it doesn’t matter that most of the
   Developer’s causation allegations concern CTHC’s defective construction;
   what matters is that some of those allegations concern Archer Western’s
   allegedly defective work on the Project’s drainage systems.
          Second, Illinois law doesn’t require express allegations. As one Illinois
   state court put it, the contention that the relevant documents “must
   explicitly identify the claim that is within the ‘additional insured’ coverage
   represents an unduly narrow reading of the applicable test.” Pekin Ins. Co. v.
   Hallmark Homes, LLC, 912 N.E.2d 250, 257 (Ill. App. Ct. 2009). And as
   another explained, the relevant documents “need not allege or use language
   affirmatively bringing the claims within the scope of the policy.” W. Cas. &
   Sur. Co. v. Adams Cnty., 534 N.E.2d 1066, 1068 (Ill. App. Ct. 1989); see also
   Int’l Ins. Co. v. Rollprint Packaging Prods., Inc., 728 N.E.2d 680, 688 (Ill. App.

                                     No. 20-50966

   Ct. 2000). That’s for good reason: “The question of coverage should not
   hinge on the draftsmanship skills or whims of the plaintiff in the underlying
   action.” Int’l Ins. Co., 728 N.E.2d at 688 (citing W. Cas. & Sur. Co., 534
   N.E.2d at 1068).
             Third, Arch’s principal authority—Amerisure Mutual Insurance Co. v.
   Microplastics, Inc., 622 F.3d 806 (7th Cir. 2010)—is critically different. In that
   case, a vehicle-parts manufacturer (Microplastics) produced faulty door-
   latch assemblies and then sold them to an original equipment manufacturer
   (Valeo). Id. at 808. Microplastics sued for breach of contract, id. at 809;
   Valeo counterclaimed seeking “setoff or recoupment of all damages it has
   incurred on account of Microplastics’ breaches,” including “costs charged
   to Valeo [by its customers] associated with the defects,” id. at 811.
             The question presented was whether the “general allegations” in
   Valeo’s counterclaim triggered the insurance provider’s duty to defend
   Microplastics. Ibid. The Seventh Circuit answered no. In reaching that
   answer, the court recognized that the allegations “d[id] not logically
   foreclose the theoretical possibility that” there was “potentially covered
   damage to property beyond the defective products.” Ibid. Still, the
   allegations were so “vague” that it required “hypothesizing situations” to
   “fill in details” to show the potentiality of covered “property damage.” Id.
   at 812.
             Such hypothesizing isn’t necessary here. The Developer specifically
   alleged the relevant defective construction, the property damage caused by
   the drainage systems, and when the damage occurred. There’s no reasonable
   dispute that multiple parties, including Archer Western, were working on the
   Project. And it’s reasonable to infer that work performed by one
   subcontractor likely damaged another subcontractor’s work on this Project.

                                           13
Case: 20-50966     Document: 00516131058             Page: 14   Date Filed: 12/14/2021

                                     No. 20-50966

   It’s therefore more than a “theoretical possibility” that the allegations in the
   Developer’s underlying arbitration raised a covered-property-damage claim.
                                          2.
          Arch also argues that the Developer’s allegations do not trigger the
   Policy’s “property damage” provision because Archer Western damaged
   only its own work. It’s true that, under Illinois law, an insured’s damage to
   its own work cannot constitute covered “property damage.” Eljer Mfg., 757
   N.E.2d at 503 (quotation omitted). But it’s incorrect that the own-work
   exclusion applies here.
          Take, for example, Ohio Casualty Insurance Co. v. Bazzi Construction
   Co., 815 F.2d 1146 (7th Cir. 1987) (Illinois law). There, a construction
   company negligently poured concrete while renovating a building parking
   garage, compromising the structural integrity of the whole garage. Id. at 1147.
   The court concluded that the company caused damage to work other than its
   own. Id. at 1148. Specifically, the court explained: “Had [the company]
   contracted to construct an entirely new building . . . any damage to or defects
   in that building, which would be defined as the property or work product of
   [the company], would not be covered under the policy. But that is not the
   case now before us.” Id. at 1148–49. Rather, the complaint alleged “damage
   to property other than [the company’s] own work or product, namely the
   structure of the existing garage.” Id. at 1149.
          So too here. Archer Western’s work involved installing the drainage
   systems. And the subcontract expressly exempted from Archer Western’s
   scope of work the property that was damaged—e.g., preparing the abutment

                                          14
Case: 20-50966       Document: 00516131058               Page: 15    Date Filed: 12/14/2021

                                          No. 20-50966

   soil, as well as providing bearing pads and riprap. So the Developer alleged
   damage to property outside Archer Western’s own work. 4
                                      *        *         *
           The Developer’s claims against the Project’s general contractor
   implicate defective construction of the Project’s drainage systems. Archer
   Western constructed those drainage systems. Therefore, Archer Western’s
   CGL insurer (Arch) owes a duty to defend the general contractor (CTHC)
   in its underlying litigation with the Developer. The district court’s judgment
   in favor of Arch is REVERSED.

           4
            Arch insists that Zurich forfeited any arguments responding to this “alternative
   reason[].”Again, no. See supra n.3; Hoyt, 927 F.3d at 296 n.2; Ramirez, 557 F.3d at 203.
