Item 1.  Security and Issuer.

This Amendment No. 1 to Schedule 13D ("Amendment No. 1") relates to shares of the common stock, par value $0.0001 per share (the "Common Stock"), of Hill International, Inc., a Delaware corporation (the "Issuer").  The address of the principal executive offices of the Issuer is One Commerce Square, 2005 Market Street, 17th Floor, Philadelphia, PA 19103.

This Amendment No. 1 is jointly filed by and on behalf of each of David L.

Irvin E. Richter, Brady H. Richter and Stuart S. Richter.  Such persons were included therein at the time of the Initial Filing as members of an expressly affirmed group.  In a subsequent amendment to the Initial Filing, Mr. Irvin E. Richter and Mr. David Richter elected to jointly file a single Schedule 13D pursuant to Rule 13d-1(k) under the Securities Exchange Act of 1934, as amended, to report each person's beneficial ownership of shares of the Issuer.  In a further amendment to the Initial Filing, Mr. Irvin E. Richter indicated that he was no longer electing to file Schedule 13D jointly with Mr. David Richter. The Reporting Persons' Amendment No. 1 is being filed to amend and supplement the information previously disclosed with respect to Mr. David Richter's beneficial ownership of shares of the Issuer.

Item 2.  Identity and Background.

(a)  This Amendment No. 1 is jointly filed by and on behalf of each of the Reporting Persons.  As of the date of this Amendment No. 1, Mr. David Richter is the sole member and owns all of the outstanding limited liability company interests in Richter Capital, and serves as its Chairman and Chief Executive Officer.  The Reporting Persons are filing this Amendment No. 1 jointly pursuant to a Joint Filing Agreement dated as of July 6, 2018 (the "Joint Filing Agreement"), a copy of which is attached hereto as Exhibit 99.1 and incorporated herein by reference.

Each of the Reporting Persons declares that neither the filing of this Amendment No. 1 nor anything contained herein shall be construed as an admission that such Reporting Persons are, for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, the beneficial owners of any of the shares of Common Stock covered by this Amendment No. 1.

(b)  The business address of Mr. David Richter is 274 Carter Road, Princeton, NJ 08540.  The business address of Richter Capital is 274 Carter Road, Princeton, NJ 08540.

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

The shares of Common Stock beneficially owned by Mr. David Richter were acquired through a gift and through purchases of shares from the Issuer, including shares acquired through grants and awards made to Mr. David Richter in connection with certain compensatory arrangements between the Issuer and Mr. David Richter while he was an employee of the Issuer.  The shares of Common Stock beneficially owned by Richter Capital were acquired through an initial capital contribution made by Mr. David Richter.

Item 4. Purpose of Transaction.

The shares covered by this Amendment No. 1 are being held by the Reporting Persons for investment purposes only.  The Reporting Persons have no present plans or intentions to acquire additional shares of the common stock of the Issuer, or to cause any other person to dispose of shares of common stock of the Issuer.  Aside from estate planning and tax planning transactions, the Reporting Persons have no present plans or intentions to dispose of shares, or to cause any other person to dispose of shares, of the Issuer. However, based on a variety of factors including, without limitation, the Issuer's financial position, the market price of the shares of the Issuer's common stock, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their ownership of shares of the common stock of the Issuer as they deem appropriate including, without limitation, purchasing additional shares, disposing of some or all of their shares, or (to the extent permitted by applicable law) engaging in the short selling of, or any hedging or similar transaction with respect to, the shares of Common Stock.  Any purchase or sale of shares may be on the open market, in block trades, private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

Except as described above, no Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in paragraphs (a) through (j) of Item 4 of Schedule 13D.  However, the Reporting Persons may exercise any and all of their rights as shareholders of the Issuer in a manner consistent with their ownership interests and investment objectives.  The Reporting Persons reserve the right to formulate other plans and/or make other proposals, and take such actions with respect to the shares of common stock they own, including any or all of the actions set forth in paragraphs (a) through (j) of Item 4 of Schedule 13D and any other actions as the Reporting Persons may determine.

Item 5.  Interest in Securities of the Issuer.

(a)  The aggregate percentage of shares reported owned by each person named herein is based upon 52,960,817 shares of common stock outstanding as of March 31, 2018, according to the Issuer's Quarterly Report on Form 10-Q, for the quarterly period ended March 31, 2018.  As of July 6, 2018, Mr. David Richter beneficially owned 4,073,467 shares of common stock of the Issuer (including 3,002,840 shares owned by Richter Capital), constituting approximately 7.69% of the shares of common stock outstanding of the Issuer and Richter Capital beneficially owned 3,002,840 shares of common stock of the Issuer, constituting approximately 5.67% of the shares of common stock of the Issuer outstanding.

(b)  Mr. David Richter has (i) the sole power to vote or direct the vote, and the sole power to dispose or direct the disposition, of the 1,070,627 shares of common stock of the Issuer held in Mr. David Richter's name or in the names of his minor children and (ii) the shared power to vote or direct the vote, and the shared power to dispose or direct the disposition, of the 3,002,840 shares of common stock of the Issuer held by Richter Capital.

(c)  None of the Reporting Persons has conducted any transactions in Issuer securities during the past sixty days.

(d)  No person other than the Reporting Persons is known to have the right to receive, or the power to direct the receipt of dividends from, or proceeds from the sale of, the shares of common stock of the Issuer owned by them.
