AMENDMENT NO. 4 TO
STATEMENT ON SCHEDULE 13D

Introductory Note: This Amendment No. 4 to Statement on Schedule 13D
is being filed by Enron Corp., an Oregon corporation ("Enron"), Enron North
America Corp., a Delaware corporation ("ENA"), and Joint Energy Development
Investments II Limited Partnership, a Delaware limited partnership ("JEDI II"),
which are collectively referred to as the "Reporting Entities." All information
herein with respect to Quanta Services, Inc., a Delaware corporation (the
"Issuer"), and the common stock, par value $.00001 per share, of the Issuer
("Common Stock") is presented to the best knowledge and belief of the Reporting
Entities. Capitalized terms used and not defined in this Amendment No. 4 to
Statement on Schedule 13D have the meanings set forth in the Schedule 13D, as
amended. The joint Schedule 13D of Enron, ENA, and JEDI II filed October 9,
1998, as amended by a Schedule 13D/A of Enron, ENA, JEDI II, and ECT Merchant
Investments Corp., a Delaware corporation ("EMIC") filed January 12, 1999, as
further amended by a Schedule 13D/A of Enron, ENA, EMIC and JEDI II filed
October 18, 1999, as further amended by a Schedule 13D/A of Enron, ENA, EMIC
and JEDI II filed January 12, 2000, is further amended as follows:

ITEM 2. IDENTITY AND BACKGROUND.

The Schedules to this statement report current information regarding the
officers and directors of Enron, ENA, and Enron Capital II Corp. None of the
Reporting Entities nor, to their knowledge, any person listed on the Schedules
hereto, has been, during the last five years (i) convicted in a criminal
proceeding (excluding traffic violations or similar misdemeanors) or (ii) a
party to a civil proceeding and as a result of such proceeding was or is
subject to a judgment, decree or final order enjoining future violation of, or
prohibiting or mandating activities subject to, U.S. federal or state
securities laws or finding any violation with respect to such laws.

ITEM 3. SOURCE AND AMOUNT OF FUNDS AND OTHER CONSIDERATION; ITEM 4. PURPOSE OF
TRANSACTION; ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS
WITH RESPECT TO SECURITIES OF THE ISSUER.

Enron has indirect control over the general partner of SE Thunderbird L.P.
("Thunderbird"), a partnership which held a Convertible Promissory Note due
2010 dated October 5, 1998 issued by the Issuer in the original principal amount
of $12,337,500 (the "Thunderbird Note"). JEDI II held a note of like tenor and
description in the original principal amount of $37,012,500 (the "JEDI II Note")
(collectively, the "Convertible Notes").

On April 14, 2000, Thunderbird and JEDI II agreed to transfer their entire
interest in the Convertible Notes to UtiliCorp United Inc. in a private
transaction. The JEDI II Note was purchased for $154,392,586.16 plus the accrued
interest balance thereon. The Thunderbird Note was purchased for $51,464,195.39
plus the accrued interest balance thereon. Such amounts were actually paid to
Thunderbird and JEDI II on April 24, 2000.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

As a result of the transfers described above, JEDI II, Enron and ENA have no
beneficial interest, dispositive power or voting power with respect to any
shares of Common Stock.

Since the Reporting Persons no longer beneficially own more than five percent
of the Common Stock and have filed this statement, they are no longer subject
to filing obligations under Section 13 of the Securities Exchange Act of 1934
with respect to the securities of the Issuer.





Page 6 of 13 Pages


Other than the transactions described above and in the Schedule 13D/A filed
January 12, 2000, none of the Reporting Entities, nor to their knowledge any of
the persons named in the Schedules attached hereto, has effected any
transaction in the Common Stock during the preceding sixty days.

ITEM 7. MATERIAL TO BE FILED AS EXHIBITS.

(i) Offer letter dated April 14, 2000 from UtiliCorp United Inc.
to JEDI II.

(ii) Offer letter dated April 14, 2000 from UtiliCorp United Inc.
to Thunderbird.

After reasonable inquiry and to the best knowledge and belief of the
undersigned, the undersigned certify that the information set forth in this
statement is true, complete and correct.
