     Re:    ICF Kaiser International, Inc. (1-12248) 
            Post-effective Amendment No. 1 on Form S-3 filed April 21, 1997 to
            Registration Statement on Form S-1 (No. 333-16937)
                   (declared effective December 5, 1996)

Ladies and Gentlemen:

     Pursuant to Rule 477 under the Securities Act of 1933, we hereby request
that the above-referenced Post-effective Amendment No. 1 be withdrawn. We have
been informed by Mr. Calio that ICF Kaiser International, Inc. is not eligible
to use Form S-3 for the above-referenced Post-effective Amendment No. 1 at this
time. Such withdrawal is consistent with the public interest and the protection
of investors for the following reason.

     Mr. Calio explained to us that in August 1997 ICF Kaiser International,
Inc. will be eligible to use Form S-3 in connection with its required 10(a)(3)
update filing to the above-referenced Registration Statement. ICF Kaiser
International, Inc. intends to file Post-effective Amendment No. 2 on Form S-3
in August 1997 to accomplish the required 10(a)(3) filing.

     Please advise Cynthia L. Hathaway, our inside counsel, at 703-934-3103 of
your decision concerning this application. Thank you for your prompt assistance
in this matter.

                              Sincerely,
