Baton Rouge, LA  70809

Ladies and Gentlemen:

      We have acted as special Louisiana counsel to The Shaw Group Inc. (the
"Company") and certain of its subsidiaries set forth on Exhibit A to this
opinion (such subsidiaries, the "Louisiana Subsidiary Guarantors") with respect
to the preparation of the Registration Statement on Form S-4 (the "Registration
Statement") filed with the Securities and Exchange Commission in connection with
the registration by the Company under the Securities Act of 1933, as amended
(the "Securities Act"), of (i) the offer and exchange by the Company (the
"Exchange Offer") of $253,029,000 aggregate principal amount of its 10 -3/4%
Senior Notes Due 2010 (the "Initial Notes"), for a new series of notes bearing
substantially identical terms and in like principal amount (the "Exchange
Notes") and (ii) the guarantees (the "Guarantees") of certain subsidiaries of
the Company listed in the Registration Statement as guarantors (the "Subsidiary
Guarantors") of the Initial Notes and the Exchange Notes. The Initial Notes and
the Exchange Notes are collectively referred to herein as the "Notes." The
Initial Notes were issued, and the Exchange Notes will be issued, under an
Indenture dated as of March 17, 2003 among the Company, the Subsidiary
Guarantors and The Bank of New York, as Trustee (the "Indenture"). The Exchange
Offer will be conducted on such terms and conditions as are set forth in the
prospectus contained in the Registration Statement to which this opinion is an
exhibit.

      We have examined originals or copies, certified or otherwise identified to
our satisfaction, of (i) the Registration Statement and (ii) the Indenture. We
have also examined the originals, or copies certified or otherwise identified to
our satisfaction of the Restatement of the Articles of Incorporation of the
Company, as amended, its By-Laws, as amended and restated, and similar
organizational documents of the Louisiana Subsidiary Guarantors, certificates of
public officials, certificates of officers of the Company and the Louisiana
Subsidiary Guarantors and such other certificates, documents and corporate
records as we have deemed relevant and necessary as the basis for the opinions
expressed herein. In our examination of the aforementioned, we have assumed
without investigation the authenticity of the originals of such documents and
the conformity to originals of all documents submitted to us as copies, and the
authenticity of the originals of such latter documents, the genuineness of all
signatures, the legal capacity of natural persons and the accuracy of the
statement contained in such certificates. In connection with this opinion, we
have assumed that the Registration Statement, and any amendments thereto
(including post-effective amendments), will have become effective and the
Exchange Notes will be issued and sold in compliance with applicable federal and
state securities laws and in the manner described in the Registration Statement.

      Based upon the foregoing and in reliance thereon, and after examination of
such matters of laws as we deem applicable or relevant hereto, and subject to
the other assumptions and qualifications below, it is our opinion that:

      We are members of the bar of the State of Louisiana and we express no
opinion as to the laws of any jurisdiction other than those of the State of
Louisiana and the United States of America. This opinion is rendered solely for
your benefit with the exception that with respect to matters herein that are
governed by Louisiana law, Vinson & Elkins L.L.P. may rely on this opinion as to
matters of Louisiana law for the purposes of the opinion such firm is providing

      We hereby expressly consent to the reference to our firm in the prospectus
and each related prospectus supplement forming a part of the Registration
Statement, to the inclusion of this opinion as an exhibit to the Registration
Statement and to the filing of this opinion with any appropriate governmental
