OPINION
EPGT Texas Pipeline, L.P., successor to PG & E Texas Pipeline, L.P. (PG & E) 1 appeals a final summary judgment granted in favor of the appellee, Harris County Flood Control District (“HCFCD”). PG & E seeks damages resulting from the herniation and displacement of its gas pipeline in the City of South Houston, as a result of HCFCD’s nearby drainage excavation project. We conclude that (1) the Texas Tort Claims Act (“TTCA”) governs sovereign immunity for claims in tort against the State and the political subdivisions of the State, and PG & E does not allege a claim in tort for which the TTCA provides a waiver of immunity; and (2) the Water Code waives HCFCD’s immunity as to PG & E’s breach of contract claim, but the trial court properly granted summary judgment, because PG & E is not an intended third party beneficiary to the contract upon which it bases its claim. We therefore affirm the summary judgment as to PG & E’s tort and contract claims. We reverse and render the summary judgment on PG <& E’s inverse condemnation claim, however, as the Harris County Courts at Law have exclusive jurisdiction over such a claim, and the trial court thus lacked jurisdiction to enter summary judgment on the claim.
The Facts and the Procedural History
In 1961, HCFCD acquired an easement and a perpetual license from the Galveston, Houston, and Henderson Railroad Company (the “Railroad”), for real property located in Berry Bayou, Harris County. PG & E owns, operates, and maintains a natural gas pipeline lying in an adjacent right of way, acquired from its predecessor-in-interest, the Lo-Vaca Gathering Company.
In 1997, HCFCD executed a construction contract with Ramex Construction Company (Ramex), to improve drainage in the existing Berry Bayou ditch. PG & E’s pipeline runs across and parallel to the Ramex construction site. During construction, Ramex used motor-driven vehicles to remove two concrete double-box culvert structures that ran parallel to the PG & E pipeline. Ramex also removed soil supporting both the concrete double-box culverts and PG & E’s pipeline. Ramex’s actions removed the lateral support of the pipeline, causing it to shift sideways and downward four feet. The pipeline sustained a lateral bulge of approximately twelve and one-half feet along a 500 foot portion of the pipeline. Because of these events, PG & E had to remove the pipeline from service and repair it.
*334 In November 1998, PG & E sued both HCFCD and Ramex for breach of contract, declaratory judgment, strict liability for removal of naturally necessary support, and negligence. PG & E also asserted an inverse condemnation claim solely against HCFCD. In a second amended petition, PG & E pleaded that the TTCA conferred jurisdiction upon the trial court. In a later supplemental amended petition, PG & E further alleged that HCFCD had consented to suit for breach of contract, based upon section 49.006 of the Texas Water Code. PG & E sought $488,251.78 in actual damages for repairs and lost profits, and $500,000 in exemplary damages, as well as attorney’s fees and interest. HCFCD counterclaimed for trespass and negligence, alleging that PG & E damaged the bayou, resulting in additional project costs to it of up to $401,699.65.
In December 2001, HCFCD filed a traditional and a no-evidence motion for summary judgment. In March 2002, the trial court granted HCFCD’s motions. PG & E appeals the trial court’s final judgment granting HCFCD’s motions for summary judgment. 2
HCFCD’s Sovereign Immunity
A motion for summary judgment may raise a challenge to a trial court’s subject-matter jurisdiction.
City of Hedwig Village Planning & Zoning Comm’n v. Howeth Invs., Inc.,
Under the common-law doctrine of sovereign immunity, a unit of government cannot be sued without its consent.
State v. Terrell,
Here, HCFCD moved for summary judgment claiming immunity from suit. PG & E thus must allege facts sufficient to show that HCFCD waived immunity to the causes of action PG & E asserts. PG & E maintains that HCFCD has waived immunity from suit pursuant to section 101.021(1) of the TTCA and section 49.006 of the Texas Water Code. See Tex. Crv. Prac. & Rem.Code Ann. § 101.021; Tex. Water Code Ann. § 49.006 (Vernon 2000).
Standard of Review
Summary judgment for a defendant is proper if the defendant negates at least one element of each of the plaintiffs theories of recovery, or pleads and conclusively establishes each element of an affirmative defense.
Science Spectrum, Inc. v. Martinez,
Thus, as movant on the affirmative defense of sovereign immunity, HCFCD has the burden to establish all the essential elements of the defense as a matter of law.
Montgomery v. Kennedy,
The Negligence Claim
The TTCA waives sovereign immunity for property damage in the following circumstances: (1) an injury caused by a government employee’s operation or use of a motor-driven vehicle or motor-driven equipment and (2) the government employee would be personally liable to the claimant according to Texas law. Tex. Civ. Prac. & Rem.Code Ann. § 101.021(1)(A)-(B) (Vernon 1997). Relying on these provisions, PG & E contends that the Legislature has waived HCFCD’s sovereign immunity as to PG & E’s negligence claim for property damage. HCFCD responds *336 that it did not waive its sovereign immunity as to PG & E’s negligence claims, because the undisputed facts show that no State employee operated a motor-driven vehicle that caused the damage to PG & E’s pipeline. Rather, Ramex, an independent contractor, operated the motor-driven vehicles. The waiver of immunity provision in the TTCA thus does not apply under these facts. PG & E replies that a fact issue exists regarding whether Ramex acted as HCFCD’s independent contractor — as HCFCD contends — or whether Ramex was a de facto state “employee,”'— as PG & E contends-thus falling within the TTCA waiver of immunity.
Section 101.021 of the TTCA provides that a governmental unit is liable for:
property damage, personal injury, and death proximately caused by the wrongful act or omission or the negligence of an employee acting within his scope of employment....
Tex. Crv. Prac. & Rem.Code Ann. § 101.021(1) (emphasis added).
The TTCA further defines “employee” as
a person, including an officer or agent, who is in the paid service of a governmental unit by competent authority, but does not include an independent contractor, an agent or employee of an independent contractor, or a person who performs tasks the details of which the governmental unit does not have the legal right to control.
Id. § 101.001(2) (Vernon Supp.2004) (emphasis added). Thus, whether the trial court properly granted summary judgment on PG & E’s tort claims depends on whether fact issues exist as to Ramex’s status as an independent contractor.
In determining whether a worker is an employee or an independent contractor, the focus is on who has the right to control the details of the work.
Exxon Corp. v. Tidwell,
HCFCD presented the following undisputed evidence to show that Ramex was an independent contractor on the Berry Bayou Project: (1) Ramex furnished the equipment and supplies to perform the job, including the motor-driven vehicles at issue; (2) HCFCD hired Ramex by the job, as a result of a bid process; and (3) HCFCD paid Ramex by the job, according to its bid. HCFCD further provided deposition testimony from Rosbell Ramos, a Ramex employee, that his company decided the means and methods used to remove the double-box culverts, and that no one from Harris County told him how to do it. We hold that HCFCD presented competent summary judgment evidence to estab *337 lish Ramex’s status as an independent contractor.
In response, PG & E points out that Brenda Trevino, the HCFCD Berry Bayou project manager, stated in deposition testimony that PG & E’s pipeline must be “field-located,” by HCFCD before construction commences. Ms. Trevino also testified that HCFCD made the decision to install sheetpile walls to provide additional lateral support to the pipeline. Trevino noted, however, that no one from HCFCD evaluated “the sufficiency of Ramex’s work in connection with the removal of the original section of box culvert.” When asked about what she relied on in determining whether Ramex’s work was sufficient, she testified, “I’m relying on the fact that the construction project is put in place as per the plans and on the expertise of the field inspection crew and the experts that have been employed.” She further stated that the field inspection crew consisted of HCFCD personnel that observed Ramex’s activities.
In determining independent contractor status, the focus is on the right to control the
details
of the work.
Exxon Corp.,
In addition to Trevino’s testimony, PG & E relies on conditions in the HCFCD/Ra-mex contract to establish that Ramex is not an independent contractor. These provisions acknowledge that a county-designated engineer may furnish specifications to, supervise, and ask Ramex to discharge, any Ramex employees who do not “perform work in a proper and skillful manner.” PG & E contends that the authority granted in these contract provisions establishes a fact issue as to whether HCFCD retained control over Ramex. These contract provisions, however, indicate control over the general requirements of the project, and its proper completion, but do not show control over the details of Ramex’s work with regard to Ramex employees use of motor-driven vehicles — the standard for determining whether a party is an employee or independent contractor within the scope of section 101.021.
See
Tex. Crv. Prac. & Rem.Code Ann. § 101.021;
Exxon Corp.,
867 S.W.2d
at 21; see also St. Joseph Hosp. v. Wolff,
PG & E further relies on a project manual HCFCD sent to Ramex and all other *338 bidders for the project. PG & E contends that this manual requires Ramex to remove the double-box culverts that provided the lateral support to the soil surrounding the pipeline. In the manual, section B of the Work Sequence states that “a major work activity” includes removing an existing 2-12'xl2'x600 concrete box. PG & E also directs us to a manual provision dictating that HCFCD decide the controls Ramex is to employ, including erosion and sediment controls. Project specifications, however, do not show a right to control the details of the work. For example, the manual does not direct HCFCD to use motor-driven equipment to remove the double-box culverts supplying the lateral support. Moreover, PG & E has not presented any evidence to show that the manual provisions and directions are in fact attributable to HCFCD. The manual on which PG <& E relies indicates that TSC Engineering prepared it. PG & E neither disputes the manual’s author, nor does it allege that TSC Engineering also served as HCFCD’s employee for purposes of the TTCA. Accordingly, PG & E has not established a fact issue concerning HCFCD’s requisite right of control over the details of Ramex’s work, based on the project manual’s provisions.
After reviewing the summary judgment evidence in a light most favorable to PG
&
E, including the contract, the deposition testimony, and the manual, we agree with the trial court that PG & E did not raise a genuine issue of fact as to whether HCFCD exerted sufficient control over the details of Ramex’s work.

If no dispute exists as to the controlling facts and only one reasonable conclusion can be inferred, the question of whether the relationship which exists is that of an employee or an independent contractor is a question of law.

Strict Liability
PG & E contends that the trial court erred in granting summary judgment on its strict liability claims for removal of the pipeline’s lateral and subjacent support. HCFCD moved for summary judgment, contending that PG & E did not allege any waiver of immunity from suit on this ground. PG & E responds that TTCA section 101.021(1) waives HCFCD’s sovereign immunity. See Tex. Crv. Prac. & Rem. Code Ann. 101.021(1). Although some authority exists for strict liability claims for removal of lateral and subjacent support, 4 we disagree that section 101.021(1) waives HCFCD’s immunity from suit for such claims.
HCFCD is immune from suit unless the Legislature has waived immunity in plain and unambiguous terms.
Kerrville State Hosp. v. Fernandez,
28 S.W.3d
*339
1, 3 (Tex.2000);
Fed. Sign,
PG & E has failed to present any authority, and we find none, allowing a party to pursue a claim of strict liability for removal of lateral and subjacent support against a governmental entity cloaked with sovereign immunity. At least one other court has held that strict liability claims do not fall within the waiver provisions in section 101.021.
See Univ. of N. Tex. v. Harvey,
Breach of Contract
The trial court granted HCFCD’s summary judgment and no-evidence summary judgment on PG & E’s breach of contract claim. HCFCD moved for summary judgment on the grounds that (1) it is immune from suit, and (2) PG & E is not a third party beneficiary of the contract it claims HCFCD breached. PG & E responds that the trial court has jurisdiction over contract claims against HCFCD based on section 49.066 of the Texas Water Code and section 262.001 of the Local Government Code. PG & E further contends that it is an intended third party beneficiary of the HCFCD/Railroad contract. We first address whether PG & E pleaded a basis for waiving HCFCD’s sovereign immunity.
The Texas Water Code provides:
A district may sue and be sued in the courts of this state in the name of the district by and through its board. A suit for contract damages may be brought against a district only on a written contract of the district approved by the district’s board. All courts shall take judicial notice of the creation of the district and of its boundaries.
Tex. WateR Code Ann. § 49.006(a).
Courts have construed similar language in other statutes to waive immunity from suit.
See Missouri Pac. R. Co. v. Browns Navigation Dist.,
To claim third party beneficiary status, PG & E relies on language in the HCFCD/Railroad contract that obligates *340 HCFCD not to interfere with the activities of the Railroad’s licensees, in particular:
It is expressly agreed and understood that this license is made and given on condition that [HCFCD’s] use of the property under this license shall not interfere with the [Railroad’s] and its successors’, licensees’, invitees’ and assigns’ operations over, or upon said property, nor with maintenance of or repairs to its tracks or any of its facilities upon said property.
PG & E argues that this section confers enforceable third party rights upon a limited class of persons, including the Railroad’s other licensees. PG & E contends that the contract affords it rights as the successor of a Railroad licensee, namely, the Lo-Vaca Gathering Company, to which the Railroad granted a pipeline license in 1964.
PG & E further relies on the HCFCD/Railroad contract’s non-waiver clause:
It is expressly covenanted and agreed that no waiver by Licensor, its successors or assigns, of any condition herein set forth shall extend to or affect or be deemed to waive any other breach (whether prior or subsequent) of such condition herein set forth.
PG & E contends that these clauses together demonstrate an intent to confer legally enforceable benefits upon the Railroad’s licensees, particularly because the contract does not disclaim any third party beneficiary rights. HCFCD responds that the Railroad contract obligates HCFCD to the Railroad for conduct that interferes with the Railroad’s other licensees, but it does not elevate PG & E to an intended beneficiary, with authorization to sue HCFCD directly for a breach.
Unambiguous contracts — as the parties agree this one to be — are construed as a matter of law.
Coker v. Coker,
In determining whether a third party has a right to enforce a contract, courts look to the express intent of the contracting parties.
MCI Telecomms. Corp v. Tex. Utils. Elec. Co.,
In MCI, Texas Utilities (TU) sought to recover attorney’s fees for a breach of a contract between MCI and the Missouri Pacific Railroad (MoPac). TU claimed it was a third party beneficiary of the MCI/MoPac contract as a licensee, and that MCI had damaged TU’s poles in laying fiber optic cable along the easement. The MCI/MoPac contract explicitly provided, however, that “neither this Agreement, nor any term or provision hereof, nor any inclusion by reference, shall be construed as being for the benefit of any party not in signatory hereto.” Id. at 649-50. The Texas Supreme Court held that the contract’s disclaimer provision reflected that the parties had no intent to confer third party benefits under the contract. Id. at 652. The Court further observed that nothing in the contract indicated that MCI and MoPac ever intended to confer a direct benefit to TU. Id. at 652.
Although the non-interference language TU relied upon in the
MCI
case corresponds to the contract in this case, PG & E distinguishes
MCI
from the present facts on the basis that the HCFCD/Railroad contract does not contain a provision expressly disclaiming any third party rights. PG & E ignores, however, the affirmative requirement that HCFCD and the Railroad expressly contract directly for PG & E’s benefit.
See id.
at 651-52. An express disclaimer is not necessary to deny third party rights; instead, an express obligation is necessary to confer them.
See Union Pac. R.R. Co. v. Novus Int’l, Inc.,
In connection with its contract claim, PG & E contends that the trial court erred in granting summary judgment on its declaratory judgment claim. In its second amended petition, PG & E sought to have the trial court declare the parties’ rights as to the HCFCD/Railroad agreement and PG & E’s third party beneficiary status. As we have concluded that PG & E has no right to sue as an intended third party beneficiary on the HCFCD/Railroad contract, the trial court properly granted summary judgment on PG & E’s declaratory judgment claim.
Inverse Condemnation
PG & E contends that the trial court erred in granting summary judgment on its inverse condemnation claim.
The Texas Constitution provides that, “No person’s property shall be taken,
*342
damaged or destroyed for or applied to public use without adequate compensation being made, unless by the consent of such person-” Tex. Const. art. I, § 17. Inverse condemnation occurs when property is taken, damaged, or destroyed for public use without process or without proper condemnation proceedings, and the property owner attempts to recover compensation.
City of Abilene v. Burk Royalty Co.,
Jurisdiction over such claims is exclusively vested with the Harris County Courts at Law, pursuant to section 25.1032(c) of the Texas Government Code. See Tex. Gov’t Code Ann. § 25.1032(c) (Vernon 2004) (“A county civil court at law has exclusive jurisdiction in Harris County of eminent domain proceedings, both statutory and inverse, regardless of the amount in controversy.”).
In
Taub v. Aquila Southwest Pipeline Corp.,
HCFCD further contends that we should dismiss PG
&
E’s other claims because they are inherently intertwined with the inverse condemnation claim, relying on
Taub.
In
Taub,
however, the court of appeals observed that “the Harris County Civil Courts at Law have jurisdiction,
but not exclusive jurisdiction,
over a landowner’s claims, regardless of the amount in controversy....”
Taub,
Conclusion
We affirm the judgment of the trial court as to PG & E’s negligence, strict liability, breach of contract, and declaratory judgment claims. We reverse the judgment insofar as it disposes of the claim for inverse condemnation, and render that PG & E’s claim for inverse condemnation be dismissed without prejudice. We deny all other outstanding motions.
Notes
. EPGT Texas Pipeline, L.P., a subsidiary of El Paso Corporation, acquired PG & E during the pendency of this lawsuit. This is the second appeal in this case.
See Harris County Flood Control Dist. v. PG & E Tex. Pipeline, L.P.,
. The trial court’s March 12 judgment also granted PG & E’s summary judgment on HCFCD’s counterclaim. HCFCD did not appeal.
. At oral argument, PG & E contended for the first time that HCFCD waived its sovereign immunity as to all of PG & E’s claims by asserting a counterclaim in which it sought actual damages. PG & E relies upon the Texas Supreme Court’s recent decision in
Reata Constr. Corp. v. City of Dallas,
No. 02-1031,
.
See Corley v. Exxon Pipeline Co.,
. HCFCD contends that PG & E cannot raise this basis for waiver of immunity from suit for the first time on appeal because it was not before the trial court. The trial court signed its judgment on March 12, 2002. PG & E filed a second supplemental petition alleging waiver based on the Texas Water Code’s sections 49.001(a)(1) and 49.066(a) on January 14, 2002. Thus, PG & E presented this ground to the trial court.
