     Re: INTERNATIONAL FIBERCOM, INC.

Ladies and Gentlemen:

     This  firm  is  counsel  for  International  FiberCom,   Inc.,  an  Arizona
corporation  (the  "Company").  As such,  we are  familiar  with the Articles of
Incorporation  and Bylaws of the Company.  We have also acted as counsel for the
Company with respect to certain  matters in connection  with the  preparation of
the  Registration  Statement on Form S-3 registering  7,985,720 shares of Common
Stock,  no par value  (the  "Shares"),  under  the  Securities  Act of 1933.  In
addition, we have examined such documents and undertaken such further inquiry as
we consider necessary for rendering the opinion hereinafter set forth below.

     Based upon the foregoing, it is our opinion that:

     1. The Company is a corporation  duly organized and validly  existing under
the laws of the Sate of Arizona.

     2. The Shares, when issued, will be duly and validly issued, fully paid and
nonassessable.

     We acknowledge that we are referred to under the heading "Legal Matters" of
the Prospectus which is part of the Registration Statement and we hereby consent
to the use of our name in such  Registration  Statement.  Members  of our  firm,
including the undersigned,  own shares of Common Stock of the Company, amounting
to less than 1% of the  outstanding  Common  Stock of the  Company.  We  further
consent  to the  filing  of this  opinion  as  Exhibit  5.1 to the  Registration
Statement.

                                Very truly yours,

                                /s/ Christian J. Hoffmann, III

                                Christian J. Hoffmann, III
                                For the Firm
