     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 1,628,647 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
