Before MURPHY, BRIGHT, and MELLOY, Circuit Judges.
                           ___________

PER CURIAM.

      Sirti Limited Corp. (“Sirti”), an engineering firm, contracted with Seren
Innovations Incorporated (“Seren”), a subsidiary of Northern States Power, in March
1998 to design a cable installation project in St. Cloud, Minnesota. Cable
Constructors, Inc. (“CCI”) contracted with Seren to install the cable system. In July
1998, Sirti agreed, in a separate contract with Seren, to provide construction
management services on the project. Under the July agreement, Sirti agreed to
ensure that the installation of the cable complied with Sirti’s design and local safety
regulations.
      On December 11, 1998, CCI struck a gas line during the installation process.
The gas leak resulted in an explosion which killed four individuals, injured several
others, and damaged nearby property. The victims of the accident filed twenty-four
separate lawsuits against Sirti for wrongful death, personal injury, and property
damage.

       Sirti filed insurance claims under their Professional Liability Policy from
Evanston and their Commercial General Liability and Commercial Excess Liability
(Umbrella) Policy from Travelers. Evanston agreed to defend Sirti. Travelers refused
to defend because the type of work provided by Sirti at the time of the accident was
not covered under the policy.1

       Sirti filed a motion for partial summary judgment on the issue of Travelers’
duty to defend. The district court granted partial summary judgment in favor of Sirti,
finding Travelers had a duty to defend. The court did not address whether Travelers
had a duty to indemnify. Travelers timely appealed the district court’s decision.



      1
          Travelers denied they had a duty to defend in a February 1999 letter that
stated:

      Sirti contracted with Seren to provide design and engineering services
      for the cable installation project. We also understand that Sirti did not
      have employees on site at the time of the drilling which led to the
      explosion.
             ....
      Both policies contain endorsements that exclude coverage for “bodily
      injury” and “property damage” arising out of professional services
      performed by Sirti. . . . Since Sirti’s involvement in this case was as a
      provider of professional services, there would not be coverage for
      damage claims arising out of the explosion.

J.A. at A-60.

       The federal courts have limited, not general, jurisdiction. See Bender v.
Williamsport Area Sch. Dist., 

, 541 (1986). We consider our own
jurisdiction. 

sua sponte, jurisdictional issues when it appears that the
court lacks jurisdiction, even if the parties concede the issue. See Thomas v. Basham,

, 522-23 (8th Cir. 1991).

       We have jurisdiction over final judgments. See 28 U.S.C. 1291. An order
granting partial summary judgment is not final. See Liberty Mutual Ins. Co. v.
Wetzel, 424 U.S. 737,740 (1976); Cohen v. Curtis Pub’g Co., 

(8th Cir.
1964). Furthermore, Travelers could have requested the district court to enter final
judgment with “an express determination that there is no just reason for delay and
upon an express direction for the entry of judgment, which authorizes an immediate
appeal when only some parties or claims are dismissed,” but they failed to do so. See
Fed. R. Civ. P. 54(b); Reinholdson v. Minnesota, 

, 849 (8th Cir. 2003).
Accordingly, we dismiss this appeal without prejudice for lack of jurisdiction.
Travelers may pursue a timely appeal following the district court’s entry of judgment
under Rule 54(b). A certified copy of such order, if entered, shall be transmitted to
the clerk of this court.2

      Appeal dismissed.

       On a subsequent appeal from a 54(b) order, no additional briefs need be filed.
