ITEM 1.           SECURITY AND ISSUER

                  The class of equity securities to which this Statement on
Schedule 13D relates is the common stock, par value $0.0001 per share (the
"Common Stock"), of Arpeggio Acquisition Corporation, a Delaware corporation
(the "Issuer"). The principal executive office of the Issuer is 10 East 53rd
Street, 35th Floor, New York, New York 10022.

ITEM 2.           IDENTITY AND BACKGROUND.

                  This Statement is being filed by Eric Rosenfeld ("Rosenfeld").
The business address of Rosenfeld is 10 East 53rd Street, 35th Floor, New York,
New York 10022. Rosenfeld has been the Chairman of the Board, Chief Executive
Officer and President of the Issuer since its inception.

                  During the past five years, Rosenfeld has not been convicted
in a criminal proceeding (excluding traffic violations or similar misdemeanors).

                  During the past five years, Rosenfeld has not been a party to
a civil proceeding of a judicial or administrative body of competent
jurisdiction and as a result of such proceeding was or is subject to a judgment,
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to, federal or state securities laws or finding any
violation with respect to such laws.

                  Rosenfeld is a citizen of the United States.

ITEM 3.           SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

                  This filing relates to transactions contemplated by that
certain Agreement and Plan of Merger, dated December 5, 2005, by and among the
Issuer, Hill International, Inc. ("Hill") and the stockholders of Hill (the
"Merger Agreement") discussed in further detail below in Item 4.

                  In April 2004, in connection with the Issuer's formation,
Rosenfeld purchased 900,000 shares of Common Stock at a purchase price of $0.02
per share. Rosenfeld used his personal funds to purchase such shares at that
time. In May 2004, the Issuer's board of directors authorized a 1.2-to-one
forward stock split of the Common Stock, effectively lowering the purchase price
to $0.016 per share (and increasing the number of shares held by the Rosenfeld
to 1,080,000, hereinafter referred to as the "Shares").

                  The Shares do not include (i) 120,000 shares of Common Stock
held by the Rosenfeld 1991 Children's Trust, of which Rosenfeld's wife is the
sole trustee, and (ii) 750,000 shares of Common Stock that may be issued upon
exercise of warrants that are not currently exercisable and will not become
exercisable within the next 60 days.






                                  SCHEDULE 13D

                  ITEM 4.           PURPOSE OF TRANSACTION

                  Rosenfeld acquired the Shares for investment purposes.

                  (a)   Rosenfeld may acquire additional securities from time to
time in the open market or in private transactions. Rosenfeld holds warrants to
purchase an aggregate of 750,000 shares of the Issuer's Common Stock. The
warrants have an exercise price of $5.00 per share and will become exercisable
upon completion by the Issuer of a business combination with a target business.

                  (b)   On December 5, 2005, the Issuer signed the Merger
Agreement. Pursuant to the Merger Agreement, Hill will merge with and into the
Issuer (the "Merger"), with the Issuer surviving the merger. Under the terms of
the Merger Agreement, the holders of outstanding Hill securities will receive,
in exchange for such securities, an aggregate of 14,500,000 shares of the
Issuer's Common Stock. Twelve percent of the Issuer's Common Stock to be issued
to Hill stockholders at the time of the Merger will be placed in escrow to
provide the sole remedy for the Issuer's indemnity rights under the Merger
Agreement. The securities holders of Hill at the time of the Merger may receive
up to an additional 6,600,000 shares of the Issuer's Common Stock if the merged
company achieves certain earnings targets specified in the Merger Agreement for
the years 2006 through 2009.

                  Pursuant to Letter Agreement, dated April 14, 2004, between
the Issuer, EarlyBirdCapital, Inc. and Rosenfeld, when the Issuer seeks
stockholder approval of the transactions contemplated by the Merger Agreement,
Rosenfeld has agreed to vote the Shares on such proposal in accordance with the
majority of the votes cast by the holders of the shares of Common Stock issued
in the Issuer's initial public offering. Additionally, in connection with the
Merger Agreement, the stockholders of Hill and certain of the stockholders of
the Issuer, including Rosenfeld, have entered into a voting agreement ("Voting
Agreement"). Pursuant to the Voting Agreement, as amended by an amendment to the
Merger Agreement dated December 30, 2005, the Issuer's Board of Directors will
be increased to seven members, of whom five will be designees of the Hill
stockholders and two will be designees of such stockholders of the Issuer.
Additionally, these stockholders, including Rosenfeld, have agreed to vote in
favor of the election or re-election of the designees of the Hill stockholders
following the Merger through the election of directors to be held at the
Issuer's annual meeting in 2007.

                  The Merger is expected to be consummated during the first half
of 2006, after the required approval by the Issuer's stockholders and the
fulfillment of certain other closing conditions.

                  At the date of this Statement, Rosenfeld, except as set forth
in this Statement, the Merger Agreement and Voting Agreement discussed in this
Item 4, and consistent with Rosenfeld's position as Chairman of the Board, Chief
Executive Officer and President of the Issuer, has no plans or proposals which
would result in:

corporate structure;

corresponding thereto or other actions which ay impede the acquisition of
control of the Issuer by any person;

delisted from a national securities exchange or to cease to be authorized to be
quoted in an inter-dealer quotation system of a registered national securities
association;

                  (i)   A class of equity securities of the issuer becoming
eligible for termination of registration pursuant to Section 12(g)(4) of the

                  Rosenfeld beneficially owns 1,080,000 Shares of the Issuer's
Common Stock. The Shares do not include (i) 120,000 shares of Common Stock held
by the Rosenfeld 1991 Children's Trust, of which Rosenfeld's wife is the sole
trustee, and (ii) 750,000 shares of Common Stock that may be issued upon
exercise of warrants that are not currently exercisable and will not become
exercisable within the next 60 days. Rosenfeld has sole dispositive power over
the Shares. Rosenfeld beneficially owns approximately 13.0% of the Issuer's
outstanding shares of Common Stock (based upon 8,300,000 shares of Common Stock
outstanding as of November 8, 2005 as set forth in the Issuer's Quarterly Report
on Form 10-QSB for the quarter ended September 30, 2005).
