Page 4 of 10 Pages

This Amendment No. 3 amends and supplements the Schedule 13D filed by Irvin E. Richter with the Securities and Exchange Commission (the “Commission”) on July 10, 2006 (the “Initial 13D Filing”), as amended and supplemented by Amendment No. 1 to the Initial 13D Filing filed with the Commission on April 6, 2007 and Amendment No. 2 to the Initial 13D Filing filed with the Commission on December 5, 2007 (the Initial 13D Filing, as amended and supplemented by the foregoing amendments thereto, are hereinafter collectively referred to as, the “Schedule 13D”), relating to the common stock, $0.0001 par value per share, of Hill International, Inc., a Delaware corporation (the “Issuer”). Initially capitalized terms used herein that are not otherwise defined herein shall have the same meanings attributed to them in the Schedule 13D. Except as expressly provided for herein, all Items of the Schedule 13D remain unchanged.

The Initial 13D Filing identified as Reporting Persons Messrs. Irvin E. Richter, David L. Richter, Brady H. Richter and Stuart S. Richter. Such persons were included therein as members of an expressly affirmed group. Notwithstanding the fact that each of such persons expressly disclaimed beneficial ownership of the shares of the Issuer’s common stock held by the other persons, and only Messrs. Irvin E. Richter and David L. Richter were senior executives and directors of the Issuer, all of such persons elected to be included in the Initial 13D Filing because, among other things, all of them were parties to the voting agreement identified in Item 4 of the Schedule 13D.

By reason of the expiration of that voting agreement, none of such persons is considered by the Filers identified in Item 2 of this Schedule 13D/A to be part of a group, and this Schedule 13D/A has been filed by the Filers as a joint filing pursuant to Rule 13d–1(k)(1) promulgated by the Commission under the Act.

Item 2. Identity and Background.

This Schedule 13D/A is filed by Messrs. Irvin E. Richter and David L. Richter (collectively, the “Filers”). The business address of the Filers is c/o Hill International, Inc., 303 Lippincott Centre, Marlton, New Jersey 08053. Irvin E. Richter is a director and is the Chairman and Chief Executive Officer of the Issuer. He is the father of David L. Richter. David L. Richter is a director and is the President and Chief Operating Officer of the Issuer.

During the last five years none of the Filers has been (1) convicted in a criminal proceeding or (2) 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.

Each of the Filers is a citizen of the United States.

Item 3. Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated in its entirety to read as follows:

On June 28, 2006, in a private placement transaction and pursuant to the Agreement and Plan of Merger, by and among Hill International, Inc., Arpeggio Acquisition Corporation and Messrs. Irvin E. Richter, David L. Richter and Brady H. Richter (the “Merger Agreement”), the Filers acquired their shares of the Issuer in exchange for their shares of Hill International, Inc. a Delaware corporation (“Old Hill”). Pursuant to the Merger Agreement, Old Hill merged with Arpeggio Acquisition Corporation, and Arpeggio Acquisition Corporation was the surviving company of the merger. Immediately upon consummation of the merger Arpeggio Acquisition Corporation changed its name to Hill International, Inc. (“New Hill” or the “Issuer”). On the date of the merger, a number of the shares of common stock of New Hill owned by the Filers were acquired pursuant to the merger transaction in exchange for their shares of Old Hill.

On April 6, 2007, pursuant to earn-out rights arising under the Merger Agreement, the Issuer issued a total of 2,300,000 shares of its common stock (the “2006 Earn-Out Shares”), which amount included an aggregate of 1,812,217 shares issued to the Filers. The 2006 Earn-Out shares which were issued to the Filers constitute part of the consideration for the shares of Old Hill that the Filers exchanged in the merger.

On October 23, 2007, the Issuer announced the redemption of its outstanding warrants for the purchase of its common stock. In connection with the redemption of the warrants and prior thereto, 13,575,601 warrants were exercised, each for one share of common stock. The final settlement date for the exercise of the warrants was November 28, 2007. The Issuer’s issuance of the 13,575,601 shares of common stock reduced the percentage of the class of common stock that is owned by the Filers.

On April 4, 2008, pursuant to the earn-out rights arising under the Merger Agreement, the Company issued a total of 2,300,000 shares of its common stock (the “2007 Earn-Out Shares”), which amount included an aggregate of 1,812,217 shares issued to the Filers. The 2007 Earn-Out shares which were issued to the Filers constitute part of the consideration for the shares of Old Hill that the Filers exchanged in the merger.

Item 4. Purpose of Transaction.

Item 4 is hereby amended and restated in its entirety to read as follows:

The Filers acquired the shares of common stock of the Issuer for investment purposes. The Filers may in the future be awarded stock pursuant to future earn-out awards, or they may be awarded stock or options to purchase stock of the Issuer pursuant to compensatory incentive plans of the Issuer. For a description of the June 28, 2006 merger transaction, reference is made to the disclosure in the Current Report on Form 8-K (File no. 000-50781) filed by the Issuer with the Commission on July 5, 2006, which is incorporated herein by reference.
