This case resulted from the planned construction of a medical office building in Arkansas. Washington Regional Medical Center (“WRMC”) hired Citadel Group to develop the project, but the project closing never occurred due to WRMC’s concern over mounting costs. Citadel filed suit to recover its development costs against WRMC in the Circuit Court of Cook County, Illinois. WRMC removed the case to the Northern District of Illinois based on diversity jurisdiction and filed a motion to dismiss for lack of personal jurisdiction, or in the alternative, for a change of venue to the Western District of Arkansas. The district court dismissed the case for lack of personal jurisdiction. We reverse.
*759 I. Background
WRMC, an Arkansas non-profit corporation with its principal place of business in Arkansas, sent a “Request for Proposal” to several developers in various states in May 2005. WRMC’s request outlined a plan in which Washington Regional Medical Foundation, an affiliated non-profit corporation, would execute a ground lease for unimproved land to a developer. The developer would construct a medical office building on the land and, once the construction was complete, would lease part of the space back to WRMC. Citadel, a Delaware corporation with its principal place of business in Illinois, received WRMC’s request and responded with a proposal on May 13, 2005. WRMC asked Citadel for additional information on a few occasions during the following months. In June, WRMC sent Citadel an email requesting that it fill out two forms to provide additional details on the project cost breakdown and a lease and operating rate summary. In July, WRMC sent Citadel an email requesting some documentation for WRMC’s auditors. In August, WRMC provided Citadel with information on the potential of a shared parking arrangement between the medical office building site and a neighboring site. In September, WRMC sent Citadel an email asking for clarification on the invoicing process that would be used by Citadel and the entities it hired and the costs encompassed by the authorization to proceed that Citadel had asked WRMC to sign. Citadel responded to the June and July requests; the record does not reflect what response, if any, Citadel gave to WRMC in September. WRMC signed the authorization to proceed on September 15, 2005, and sent a deposit to Citadel. 1 During the negotiations, representatives of WRMC never traveled to Illinois, but representatives of Citadel traveled to Arkansas once.
The authorization to proceed encompassed “project development,” but the long-term relationship envisioned by WRMC in the request for proposal was still in the theoretical stage; the ground lease had not been executed, which necessarily precluded actual construction. The authorization was attached to Citadel’s proposal, which touted its expertise in reducing costs through special financing rather than just through “value engineering,” which Citadel warned could “result in compromising project quality.” Citadel explained in its affidavit filed in response to WRMC’s motion to dismiss that the special financing involved a public offering of commercial paper notes which would reduce finance costs as compared to a traditional mortgage. The goal of the financing was to provide WRMC with the opportunity to lease the finished space at attractive lease rates because the cost of capital for construction was lower.
After WRMC executed the authorization, it requested by email that Citadel provide it with a development calendar. Citadel responded with a calendar that *760 spanned from October 2005 to May 2006 and encompassed activities such as the selection of an architect and general contractor, zoning review, design development, credit enhancement, appraisals, title commitment, legal drafting, and many scheduled conference calls. Citadel began to engage other entities to accomplish the activities set forth in the development calendar. Citadel, WRMC, and the other entities participated in conference calls to discuss the status of the project development in November 2005 and January, February, March, April, and May 2006. 2 WRMC sent Citadel questions by email on several occasions in the intervening months. WRMC also provided Citadel with information such as its past financial statements, a proposed ground lease, and a request that three Arkansas banks be permitted to participate in the financing. In March 2006, WRMC sent Citadel an email inquiring about financing costs, which “seem[ed] very high.” On May 5, 2006, WRMC informed Citadel by fax that it was concerned about financing costs and directed Citadel not to incur further costs until WRMC’s Board of Directors voted on whether to proceed with the project. At some point after May 15, 2006, WRMC informed Citadel that it would not be closing or proceeding with the project. Citadel filed suit to recover more than $500,000 in costs incurred in the development of the project.
II. Personal Jurisdiction
We review a district court’s decision to dismiss a case for lack of personal jurisdiction de novo.
TruServ Corp. v. Flegles, Inc.,
To determine whether personal jurisdiction exists over WRMC in Illinois, we consider the Illinois long-arm statute, the Illinois constitution, and the federal constitution.
See id.
at 1276. The Illinois long-arm statute grants specific jurisdiction in several enumerated instances.
See, e.g.,
735 Ill. Comp. Stat. 5/2-209(a)(l), (7) (including the “transaction of any business” within the state or the “making or performance of any contract or promise substantially connected” with the state). It also contains a “catch-all” provision which permits a court to “exercise jurisdiction on any other basis now or hereafter permitted by the Illinois Constitution and the Consti
*761
tution of the United States.”
Id.
§ 2-209(c). Thus, the “catch-all” requirements are co-extensive with the state and federal constitutional requirements.
RAR,
The Illinois constitution requires that jurisdiction be asserted only where “it is fair, just, and reasonable ... considering the quality and nature of the defendant’s acts which occur in Illinois or which affect interests located in Illinois.”
Id.
(quoting
Rollins v. Ellwood,
The Due Process Clause of the Fourteenth Amendment prevents a state from exercising specific jurisdiction over a defendant, unless the defendant had “certain minimum contacts” with the forum state “such that the maintenance of the suit does not offend ‘traditional notions of fair play and substantial justice.’ ”
Int’l Shoe Co. v. Washington,
In analyzing whether the defendant’s contacts are sufficient to establish specific jurisdiction, we do not employ a “mechanical or quantitative” test.
Int’l Shoe,
In determining the parties’ “prior negotiations and contemplated future consequences, along with the terms of the contract and the parties’ actual course of dealing,”
id.
at 479,
Citadel claims that WRMC engaged in sufficient minimum contacts and lists twenty-four “contacts” — primarily consisting of correspondence by mail, fax, phone, and email — that should collectively give rise to specific jurisdiction in Illinois. WRMC counters that these contacts are nearly all “unilateral activities” of Citadel or responses to Citadel’s requests for information; the remaining contacts are minimal and insufficient to establish jurisdiction. 4
WRMC relies upon two cases in bolstering its argument that the bulk of the contacts in this case were the unilateral actions of Citadel and are irrelevant for purposes of establishing personal jurisdiction,
Lakeside Bridge & Steel Co. v. Mountain State Construction Co.,
In
Sungard,
a Tennessee corporation contracted for business continuity and disaster services to be provided by an Illinois business. The Illinois business filed suit in Illinois over contract payments that were not received, claiming jurisdiction based on phone calls and payments received, as well as services provided in Illinois such as contract preparation, processing, and billing. The district court noted that “making telephone calls and mailing payments into the forum state are insufficient bases for jurisdiction.”
Sungard,
We first note that
Lakeside Bridge
was decided prior to two key Supreme Court decisions,
World-Wide Volkswagen
and
Burger King,
which provided us with a more robust understanding of personal jurisdiction. Additionally, this court has frequently distinguished
Lakeside
from other cases, “based on the unique circumstances of each case.”
Madison Consulting Group v. South Carolina,
The district court concluded and WRMC argues that, like
Sungard,
the focus here should be on the property that the contract is centered on and not on the administrative services provided in Illinois. In
Sungard,
the purpose of the contract was
*764
for business continuity services in Tennessee, and the administrative services were incidental. Here, while the end result would have been construction of a building in Arkansas, the authorization was not for Citadel to begin construction. The authorization encompassed
only
project development, which consisted entirely of administrative services carried out (for the most part) in Illinois. Citadel took steps on WRMC’s behalf, with WRMC’s authorization, to procure the necessary prerequisites to constructing a building, and so its actions were not the “unilateral activities” of a party having some relationship with an out-of-state defendant.
Burger King,
Citadel has satisfied its burden of proof that WRMC engaged in sufficient minimum contacts. WRMC should have reasonably anticipated being haled into court in Illinois if Citadel ever claimed that WRMC had failed to pay for obligations incurred under the authorization: “[T]he Due Process Clause may not readily be wielded as a territorial shield to avoid interstate obligations that have been voluntarily assumed.”
Id.
at 474,
III. Conclusion
We conclude that Citadel satisfied its burden of making a prima facie showing of the existence of personal jurisdiction over WRMC in Illinois. We Revehse and Remand for proceedings consistent with this opinion. 5
Notes
. The authorization to proceed simply stated: Washington Regional Medical Center authorizes Citadel Group Limited to proceed with Project development at a fee of four percent (4%) of project costs according to the following schedule: (i) a 1% good faith deposit upon execution of this proposal, and (ii) the balance from Project funding. Washington Regional Medical Center is responsible for all legal expenses and other costs associated with Project development, except architectural and engineering fees, whether or not the Project is ultimately developed. Project costs and expenses may be included in the Project’s budget and hence, refunded to Washington Regional Medical Center at Project funding. Washington Regional Medical Center will only be responsible for architectural and engineering fees in the event Washington Regional Medical Center does not execute its space leases and ground lease.
. The record is unclear as to the number of telephone conferences in which WRMC participated, but WRMC does not deny that it participated in some of them.
. "When a State exercises personal jurisdiction over a defendant in a suit not arising out of or related to the defendant’s contacts with the forum, the State has been said to be exercising 'general jurisdiction' over the defendant." Helic
opteros Nacionales de Colombia, S.A. v. Hall,
. Citadel directs our attention to the case of
Citadel Group Ltd. v. Merle West Medical Center, Inc.,
No. 06-C-6162,
. We do not express any opinion on WRMC's motion to transfer venue for the convenience of the parties and witnesses, which the district court previously denied as moot; however, the district court may want to revisit that issue in light of the disposition of this appeal.
