*781 OPINION

JAN P. PATTERSON, Justice.
Upon consideration of appellants' motion for rehearing, we deny the motion; however, we withdraw our opinion and judgment of August 4, 2006, and substitute the following. Chevron Pipeline Company and West Texas Gulf Pipeline Company[1] appeal the district court's judgment affirming the Comptroller's[2] determination of tax liability for excavation and backfilling services and the remedial installation of cathodic protection[3] devices. Chevron argues that its purchase of these services was non-taxable. In two issues, Chevron challenges the legal sufficiency of the evidence, contending that (1) excavation and backfilling services are non-taxable "unrelated services" under Comptroller Rule 3.357, see 34 Tex. Admin. Code § 3.357 (2005), and (2) the remedial installation of cathodic protection devices was non-taxable "new construction," and not taxable "real property repair and remodeling." See Tex. Tax.Code Ann. § 151.0101(a)(13) (West 2002). We reject these contentions and affirm the district court's judgment.

FACTS AND PROCEDURAL BACKGROUND
The material facts are undisputed. The Comptroller assessed taxes against Chevron Pipeline Company during an audit period from July 1, 1991, to September 30, 1997, and against West Texas Pipeline Company for the audit period of January 1, 1992, to December 30, 1997. Chevron sought a redetermination of these tax assessments and a refund from the Comptroller. See id. §§ 111.009, .104 (West 2001). After the Comptroller denied the requests, Chevron paid the deficiency under protest and filed suit in district court seeking a refund. See id. §§ 112.051, .052, .151 (West 2001).
The district court conducted a trial de novo on Chevron's claims. See id. § 112.054 (West 2001). The record reflects that Chevron owns and operates various pipelines throughout Texas. Chevron presented two witnesses at trialpipeline integrity technologists Mark Hildebrand and Mark Stephen Caskey. Hildebrand testified on the issue of excavation and backfilling services.[4] Hildebrand explained that Chevron runs internal inspection devices through its pipelines, and he analyzes the collected data to make necessary repairs and other recommendations. Hildebrand testified that one type of repair involves "recoating" the pipeline.[5] Once Chevron determined that it was necessary to recoat a pipeline, Hildebrand explained that the pipeline would be marked and excavated; the old coating would be removed, and a new coating would be applied; then the pipeline would be re-covered, or backfilled. Hildebrand testified that there were different crews with different duties throughout the process. For example, one crew would excavate; another would strip the old coating; *782 still another would apply the new coating; and yet another crew would backfill, or cover up, the pipeline.
On cross-examination, Hildebrand testified that all of the pipelines in this case were underground and that Chevron could not recoat its underground pipelines without excavation. According to Hildebrand, all of the excavation services at issue were performed in conjunction with additional repair work. Hildebrand also stated there were no instances before the trial court in which Chevron had contracted for excavation or backfilling services apart from other repairs.
On the issue of cathodic protection, Chevron presented the testimony of Mark Stephen Caskey.[6] Caskey explained that cathodic protection is a method of protecting the pipelines by installing an anode, which serves as the object of corrosion instead of the pipeline. Caskey explained the different methods of cathodic protection that Chevron used and testified that the anodes are typically installed in separate beds away from the pipeline, a cable is run from the anode bed to a rectifier, and then from the rectifier to the pipeline. Caskey testified that the pipelines at issue all had existing cathodic protection devices and that Chevron had determined "through one means or another" that additional installations of cathodic protection devices were needed. Caskey explained that the existing cathodic protection devices were left in place and that new holes or trenches were dug to install additional cathodic protection devices.
When asked on cross-examination how and where Chevron determined to install additional cathodic protection devices, Caskey testified that the existing ground beds of anodes would deplete over time and their useful life would come to an end. According to Caskey, Chevron used the rectifiers to monitor the condition and effectiveness of the existing ground beds at two-month intervals, and once the anodes reached the end of their useful life, Chevron would install a new ground bed at that location.
At the conclusion of trial, the court granted judgment in favor of the Comptroller. Chevron requested findings of fact and conclusions of law, which the trial court entered on June 16, 2005. Specifically, the trial court found:
4. Chevron and West Texas assert that they are entitled to a refund of sales taxes wrongly assessed by the Comptroller and paid by Chevron and West Texas on their purchases of installations of cathodic protection devices and on their purchases of excavation and backfilling services. The installations of cathodic protection devices and the excavation and backfilling services were purchased by Chevron and West Texas from third-party contractors.
5. The parties have agreed to the amounts in issue with respect to the two matters in dispute as follows:
a. Cathodic protection$184,678.48
b. Excavation and backfilling $89,837.23
6. Chevron and West Texas do not contest the validity or application of Comptroller Rule 34 Tex. Admin. Code. § 3.357.
7. Chevron and West Texas owe the sales taxes as assessed by the Comptroller.
With respect to the issue of cathodic protection installations, the trial court entered additional findings of fact as follows:

*783 8. The cathodic protection installations in issue are the repair, restoration, remodeling or modification of an improvement to real property that is not used as a residence or immediately adjacent to a residence and part of a residence.
9. The cathodic protection installations made over, rebuilt, replaced or upgraded existing non-residential real property. The cathodic protection installations brought back as near as can be to its original working order non-residential real property that was broken, damaged or defective.
10. The cathodic protection installations brought back as near as could be to its original condition real property which was still operating and functional, but was faded, declined or deteriorated.
* * *
13. The cathodic protection installations did not add new, useable square footage to an existing structure.
With regard to excavation and backfilling services, the trial court found:
14. The excavation and backfilling in issue is not an unrelated service.
15. The excavation and backfilling in issue was required to perform the repairs and recoating of the pipelines owned by Chevron and West Texas.
16. The repair and recoating performed in conjunction with the excavation and backfilling is taxable.
17. The performance of the excavation and backfilling is not distinct and identifiable from the taxable pipeline repairs.
Based on these findings, the trial court concluded that the cathodic protection installations and excavation and backfilling services in issue were subject to sales tax and that Chevron and West Texas were not entitled to a refund. This appeal followed.

STANDARD OF REVIEW
Although the Comptroller conducted a hearing and issued a decision on Chevron's request for redetermination, judicial review in a tax refund suit brought by the taxpayer is de novo. Tex. Tax Code Ann. §§ 112.054, .154 (West 2001). The Administrative Procedure Act (APA) provides that when "the manner of review authorized by law for the decision in a contested case that is the subject of complaint is by trial de novo, the reviewing court shall try each issue of fact and law in the manner that applies to other civil suits in this state as though there had not been an intervening agency action or decision." Tex. Gov't Code Ann. § 2001.173 (West 2000).
After a de novo trial, the trial court granted judgment in favor of the Comptroller on all issues. The trial court supported its judgment with findings of fact and conclusions of law. In a bench trial, the court's findings of fact have the same force and effect as a jury verdict. Catalina v. Blasdel, 881 S.W.2d 295, 297 (Tex.1994); GATX Terminals Corp. v. Rylander, 78 S.W.3d 630, 633 (Tex.App.-Austin 2002, no pet.). Likewise, appellate courts review the factual and legal sufficiency of the trial court's findings of fact and conclusions of law according to the same standards as jury findings. Catalina, 881 S.W.2d at 297.
On appeal, Chevron challenges the legal sufficiency of the trial court's conclusions that Chevron is liable for the tax imposed on its purchases of excavation and backfilling services and the remedial installation of cathodic protection devices. Our consideration of Chevron's challenge is guided by the supreme court's decision in City of Keller v. Wilson, 168 S.W.3d 802 (Tex. 2005). In reviewing the legal sufficiency *784 of the evidence, we must view the evidence in the light most favorable to the verdict, crediting favorable evidence if reasonable jurors could, and disregarding contrary evidence unless reasonable jurors could not. See id. at 807. The test for legal sufficiency is whether the evidence would enable reasonable people to reach the judgment being reviewed. Id. at 827-28.

DISCUSSION
Chevron brings two issues on appeal. First, Chevron contends that the remedial installation of cathodic protection devices is non-taxable new construction, and not taxable repair or remodeling. Second, Chevron contends that the excavation and backfilling services purchased in conjunction with other repair services are non-taxable "unrelated services" within the meaning of Comptroller Rule 3.357. See 34 Tex. Admin. Code § 3.357. The Comptroller responds that it has consistently held that remedial installations of cathodic protection devices are not new construction, but instead constitute taxable repair or remodeling. The Comptroller further responds that excavation and backfilling services purchased in conjunction with other pipeline repair work cannot be "unrelated services" within the meaning of Rule 3.357. Under the standard of review for legal sufficiency, Chevron must demonstrate that no reasonable fact-finder could have concluded that it was not liable for the tax on the remedial installations of cathodic protection devices or its purchases of excavation and backfilling services.
Remedial Installations of Cathodic Protection Devices
The tax code defines "real property repair and remodeling" as the repair, restoration, remodeling, or modification of an improvement to real property. Tex. Tax Code Ann. § 151.0047 (West 2002). The legislature has imposed a tax on real property repair and remodeling services in section 151.0101(a)(13) of the tax code. Tex. Tax Code Ann. § 151.0101(a)(13) (West 2002). The Comptroller has exclusive jurisdiction to determine whether services fall into this category. Id. § 151.0101(b). In exercise of this jurisdiction, the Comptroller has adopted Rule 3.357. See 34 Tex. Admin. Code § 3.357 (2005).[7] Chevron does not challenge the validity or applicability of Rule 3.357.
Rule 3.357 includes the following definitions of new construction and remodeling, repair, and restoration:
(8) New constructionAll new improvements to real property including initial finish out work to the interior or exterior of the improvement. An example is a multiple story building that has had only its first floor finished and occupied. The initial finish out of each additional floor before initial occupancy or use is considered new construction. New construction also includes the addition of new, usable square footage to an existing structure. Examples are the addition of a new wing onto an existing building, or the addition of a new mezzanine level within an existing building. Reallocation of existing square footage inside a structure is remodeling and does not constitute the addition of new, usable square footage. For example, the removal or relocation of interior walls to expand the size of a room, or the finish out of an office space that was previously used for storage, is *785 remodeling. Raising the ceiling of a room or the roof of a building is not new construction unless new, usable square footage is created.
* * *
(11) Remodeling or modificationTo rebuild, replace, alter, modify, or upgrade existing real property. However, the replacement of an item that is within an operational and functional improvement to realty is not taxable remodeling or modification when the work is scheduled and periodic maintenance as defined in paragraph (7) of this subsection. . . . Work that is performed after the initial finish out has been completed is remodeling even when the improvement has not been occupied or used. For example, a prospective tenant wants the unit of a completely finished out shopping complex repainted before the tenant leases the unit. The repainting is remodeling. Partial demolition of existing nonresidential realty is taxable remodeling. The complete demolition of an existing nonresidential improvement to real property is neither remodeling nor modification and is not taxable.
(12) RepairTo mend or bring back real property that was broken, damaged, or defective as near as possible to its original working order. However, minor repair work that is performed on operational and functional improvements to realty is not taxable repair if the work is done in accordance with paragraph (7) of this subsection.
* * *
(14) RestorationAn activity that is performed to bring back real property that is still operational and functional but that has faded, declined, or deteriorated, as near as possible to its original condition. Minor restorative work that is performed within the meaning of paragraph (7) of this subsection is maintenance, not restoration.
34 Tex. Admin. Code § 3.357(a)(8), (11)(12), (14) (emphasis added).
In support of its argument that the remedial installation of cathodic protection devices is new construction and not remodeling or repair, Chevron argues that the evidence conclusively established that remedial installation of additional cathodic protection devices was new construction because it resulted in "the addition of new usable square footage." Chevron's argument misses the point. To qualify as new construction under Rule 3.357, the activity must result in "the addition of new, usable square footage to an existing structure." See 34 Tex. Admin. Code § 3.357(a)(8) (emphasis added). Although Caskey testified that the remedial cathodic protection devices were installed in new holes or new trenches, this activity does not meet the definition of "new construction" in Rule 3.357.
There is no evidence that the remedial installations of cathodic protection devices expanded the capacity of the existing pipeline. Rather the evidence demonstrates that remedial installation of cathodic protection devices simply prevents the existing pipeline from corroding. Caskey testified that all of the pipelines at issue already had existing cathodic protection devices and that Chevron would only install new anode ground beds when the rectifiers indicated that the existing ground beds were depleted or failing. Caskey also testified that the existing cathodic protection devices would be left in place to provide whatever protection remained. The remedial installations of cathodic protection devices do not add "new, usable square footage to an existing structure" *786 within the meaning of Rule 3.357 and, therefore, do not satisfy the rule's definition of "new construction." To borrow an analogy from major-league baseball, the remedial installation of cathodic protection devices is like adding stadium lights to Wrigley Field.[8] It allows you to use the existing structure for a longer period of time, but it does not increase the usable square footage of the existing structure. Chevron's arguments are contrary to this Court's opinion in GATX Terminals Corporation v. Rylander, in which we held that the plain language of Rule 3.357 contemplates something more than "the addition of new equipment." See 78 S.W.3d at 641. The evidence demonstrates that the existing cathodic protection devices remained in place. Therefore, the trial court could have properly inferred that the remedial installations of additional cathodic protection devices simply upgraded or replaced the protection provided by existing devices. Viewing this evidence in the light most favorable to the verdict, and crediting all favorable evidence that a reasonable fact-finder could believe while disregarding all contrary evidence except that which a reasonable fact-finder could not ignore, we conclude that the evidence was legally sufficient to support the trial court's findings of fact and its conclusion that Chevron was liable for the tax imposed on the installations of remedial cathodic protection devices. See City of Keller, 168 S.W.3d at 829-30.
To the extent Chevron cites other Comptroller decisions in support of its claim that remedial installations of cathodic protection devices qualify as non-taxable new construction, Chevron's efforts are unavailing. Because the Comptroller has exclusive jurisdiction to interpret whether a particular service falls within the categories of "taxable services" enumerated in section 151.0101(a) of the tax code, we defer to the Comptroller's construction of Rule 3.357. See Tex. Tax Code Ann. § 151.0101(b).[9] None of the decisions cited by Chevron involve remedial installations of cathodic protection devices. In contrast, the Comptroller has previously and consistently rejected similar claims that remedial installations of cathodic protection devices add new, usable square footage and, therefore, constitute non-taxable, new construction. See Hearing Decision No. 31,964 (Tex. Comptroller of Pub. Accounts 1996); Hearing Decision No. 28,327 (Tex. Comptroller of Pub. Accounts 1992). We overrule Chevron's first issue.
Excavation and Backfilling Services
In its second issue, Chevron challenges the legal sufficiency of the evidence to support the trial court's findings that excavation and backfilling services are not "unrelated services" and its conclusion that such services are subject to taxation. Chevron argues that because excavation and backfilling services are non-taxable when provided on a stand-alone basis, such services constitute "unrelated services" within the meaning of Comptroller Rule 3.357(a)(15). We disagree.
The legislature has imposed a tax on each sale of a "taxable item." Tex. Tax Code Ann. § 151.051 (West 2002). The term "taxable item" includes "taxable services." Id. § 151.010 (West 2002). Although excavation and backfilling services *787 are not included in the list of taxable services in section 151.0101 of the tax code, see id. § 151.0101(a), the Comptroller imposed a tax on those excavation and backfilling services purchased by Chevron in conjunction with its purchases of pipeline recoating services. The parties agree that the pipeline recoating services purchased by Chevron are taxable repair services. See Tex. Tax Code Ann. § 151.0101(a)(13); 34 Tex. Admin. Code § 3.357(a)(12). The parties likewise agree that excavation and backfilling services are non-taxable when provided on a stand-alone basis. See Tex. Tax Code Ann. § 151.0101(a). The dispute at issue thus concerns how to treat, for taxation purposes, excavation and backfilling services purchased in conjunction with pipeline repair services.
Rule 3.357 governs the taxation of the repair, remodeling, or restoration of nonresidential real property. 34 Tex. Admin. Code § 3.357. The rule requires all persons who repair, restore, or remodel nonresidential real property to collect taxes on the "total sales price . . . less separately stated charges for unrelated services." Id. § 3.357(b)(2). Rule 3.357(a)(15) provides:
A service is unrelated if:
(A) it is not the repair, remodeling, or restoration of nonresidential real property, nor a service or labor that is taxable under any other provision of the Tax Code, Chapter 151;
(B) it is of a type that is commonly provided on a stand-alone basis; and
(C) the performance of the service is distinct and identifiable. Examples of unrelated services that may be excluded from the tax base are the creation of engineering plans or architectural designs, new construction, increased capacity, and maintenance on real property.
Id. § 3.357(a)(15). The rule thus establishes a three-prong test for determining whether a service is an "unrelated service." See id. The parties agree that the excavation and backfilling services at issue meet the first prong of this testi.e., they are non-taxable services. Their dispute centers on prongs two and three and whether excavation and backfilling services are a type of service that is commonly provided on a stand-alone basis and whether the performance of such services is distinct and identifiable.
At trial, Chevron witness Mark Hildebrand testified that although Chevron at times has excavated and backfilled its pipelines without repairing them, that is not what happened in this case. According to Hildebrand's testimony, Chevron had already determined that the pipelines were in need of repair, and Chevron excavated the pipelines for the sole purpose of performing the necessary repairs. Hildebrand testified that the underground pipelines could not be recoated without excavating and backfilling and that there were no instances before the trial court in which Chevron contracted solely for excavation and backfilling services. On cross-examination, Hildebrand agreed that the basic purpose of all the contracts at issue was for repair and recoating services for which excavation was required, and not for excavation and backfilling services on a standalone basis.
On this record, we conclude that there was legally sufficient evidence to support the trial court's finding that "[t]he excavation and backfilling in issue is not an unrelated service." The evidence presented at trial demonstrates that Chevron did not contract for excavation and backfilling services on a stand-alone basis as contemplated under Rule 3.357(a)(15). Assuming arguendo that excavation and backfilling services might otherwise be "commonly *788 provided on a stand-alone basis," that is not what happened here. Thus, Chevron fails to satisfy the second prong of Rule 3.357(a)(15). Hildebrand's uncontroverted testimony establishes that Chevron's performance of excavation and backfilling services was not distinct and identifiable. This was not a situation where Chevron excavated the pipelines in order to determine whether or not repairs were needed. In this case, Chevron had already determined that repairs were in fact necessary through other means, and Chevron hired the same third-party contractors to perform both excavation and backfilling services as well as the repair and recoating services. As explained by Hildebrand, the process worked like one continuous assembly line. One crew would excavate the pipeline; another would repair or recoat the pipeline; and another crew would follow along and backfill the pipeline once the repairs were completed. In addition, Hildebrand testified on cross-examination that Chevron could not recoat its underground pipelines without excavation and backfilling and that all of the invoices reflected costs for both excavation and backfilling services as well as pipeline repair or recoating services.[10] Thus, Chevron fails to satisfy the third prong of Rule 3.357(a)(15).
Viewing the record as a whole, giving credit to all evidence favorable to the verdict, we find that no reasonable fact-finder could have ignored Hildebrand's uncontroverted testimony that Chevron did not contract for excavation and backfilling services on a stand-alone basis, even if such services could be provided on a stand-alone basis. See City of Keller, 168 S.W.3d at 807, 827-28. Hildebrand's testimony further reveals that the excavation and backfilling services at issue were a necessary and integral part of the recoating process to repair Chevron's underground pipelines, and no reasonable fact-finder could have determined that the excavation and backfilling services at issue were distinct and identifiable. See id. Accordingly, we conclude there was legally sufficient evidence to support the trial court's findings that excavation and backfilling services were required to perform the repair and recoating services and that such services were not distinct and identifiable and, therefore, did not constitute an "unrelated service" within the meaning of Rule 3.357(a)(15). We also conclude that the evidence was legally sufficient to support the trial court's conclusion that Chevron's purchase of excavation and backfilling services was subject to tax. We overrule Chevron's second issue.

CONCLUSION
Having examined the evidence presented at trial, we conclude that there was legally sufficient evidence to support the trial court's findings of fact and conclusions of law. Accordingly, we affirm the trial court's judgment.
NOTES
[1]  Because the interests of Chevron Pipeline Company and West Texas Gulf Pipeline converge, we refer to appellants collectively as "Chevron" unless otherwise noted.
[2]  Because the interests of the Comptroller of Public Accounts and the Attorney General converge, we refer to the appellees collectively as the "Comptroller."
[3]  Cathodic protection is a process used to halt or reduce the corrosion of steel pipelines.
[4]  In addition to Hildebrand's testimony, Chevron introduced into evidence copies of all of the invoices for the excavation and backfilling services at issue.
[5]  Hildebrand testified, "The term `recoating' is a blanket term we use in the pipeline industry." It can mean repainting for above-ground pipelines, or it can mean rewrapping, or putting on an epoxy coating or other sleeving for underground pipelines.
[6]  In addition to Caskey's testimony, Chevron also introduced into evidence pictures of the various types of cathodic protection installations at issue.
[7]  For convenience, we cite to the current version of Rule 3.357. Although Rule 3.357 has been amended during the pendency of this litigation, the parties agree that the amendments do not alter the substance of the rule or its application to the facts of this case.
[8]  Although Wrigley Field was originally built in 1914, the Chicago Cubs did not add lights until 1988. The first nighttime game was played on August 8 against the Philadelphia Phillies, but it was rained out after three-and-one-half innings.

[9]  Section 151.0101(b) states:

The comptroller shall have exclusive jurisdiction to interpret Subsection (a) of this section.
Tex. Tax Code Ann. § 151.0101(b).
[10]  We reject Chevron's contention that excavation and backfilling services should be treated as non-taxable in those instances where the costs for such services are itemized, or broken out, from the total invoiced amount. The Comptroller has previously determined that "separate billing for different components of a single transaction will not cause the components to be taxed separately." See Letter Ruling No. 20010267L (Tex. Comptroller of Pub. Accounts 2001). The Comptroller's determination is consistent with this Court's holding in Rylander v. San Antonio SMSA Limited Partnership, 11 S.W.3d 484 (Tex.App.-Austin 2000, no pet.).
