AMENDMENT NO. 3 TO
STATEMENT ON SCHEDULE 13D

Introductory Note: This Amendment No. 3 to Statement on Schedule 13D is
being filed by Enron Corp., an Oregon corporation ("Enron"), Enron North America
Corp., a Delaware corporation ("ENA"), formerly known as Enron Capital & Trade
Resources Corp., ECT Merchant Investments Corp., a Delaware corporation
("EMIC"), 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
knowledge and belief of the Reporting Entities. Capitalized terms used and not
defined in this Amendment No. 3 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,
EMIC and JEDI II filed January 12, 1999, as amended by a Schedule 13D/A of
Enron, ENA, EMIC and JEDI II filed October 12, 1999, is further amended as
follows:

ITEM 2. IDENTITY AND BACKGROUND.

The Schedules attached hereto set forth certain new information with
respect to the officers and directors of Enron, ENA and Enron Capital II Corp.
The filing of this statement on Schedule 13D/A shall not be construed as an
admission that any Reporting Person or any person listed on the Schedules hereto
is, for the purposes of Section 13(d) or 13(g) of the Securities Exchange Act of
1934, the beneficial owner of any securities covered by this statement.

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.

EMIC held a Convertible Promissory Note due 2010 dated October 5, 1998
issued by the Issuer in the original principal amount of Twelve Million Three
Hundred Thirty-Seven Thousand Five Hundred Dollars ($12,337,500) (the "EMIC
Note"; together with a note of like tenor and description in the amount of
$37,012,500 held by JEDI II, the "Convertible Notes"). On December 21, 1999,
EMIC transferred its entire interest in the EMIC Note to ENA, and ENA
immediately thereafter transferred the same to SE Thunderbird L.P.
("Thunderbird") in a private placement (the "Transaction"). Thunderbird funded
the $25,136,826.59 purchase price for this investment from its working capital.

In connection with that transfer, ENA transferred to Thunderbird
certain rights under both (a) the Registration Rights Agreement dated as of
September 29, 1998 among the Issuer, JEDI-II, and ENA and (b) the Securities
Purchase Agreement dated as of September 29, 1998 among the same parties (the
"Securities Purchase Agreement"), each as amended, reserving for itself the
preemptive rights and director nomination rights described in Sections 2.06 and
6.07 of the Securities Purchase Agreement.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

(a) Because Enron, pursuant to its indirect control over the voting
securities of Thunderbird, may be deemed to have voting power and dispositive
power over the EMIC Note and the Common Stock issuable pursuant thereto, the
Transaction accomplished no change in the nature or amount of its beneficial
ownership, voting power or dispositive power with respect to the securities of
the Issuer.

(b) As a result of the Transaction effected December 21, 1999, EMIC
disposed of its voting power, dispositive power, and beneficial ownership with
respect to the securities of the Issuer. Since EMIC is no longer the beneficial
owner of more than five percent of the Common Stock and has filed this
statement, it is no longer subject to filing obligations under Section 13 of the
Securities Exchange Act of 1934 with respect to the securities of the Issuer.

(c) As a result of the Transaction, ENA may be deemed to share voting
power, dispositive power, and beneficial ownership with respect to the
securities of the Issuer held by JEDI II, as described below. In addition, ENA
shares certain director nomination rights under the Securities Purchase
Agreement with JEDI II which do not entitle either JEDI II or ENA to vote shares
for the election of directors.




Page 7 of 14 Pages

If the Convertible Notes were converted in full by Thunderbird and JEDI
II, the 897,272 and 2,691,818 shares of Common Stock issuable upon such
conversions, respectively, would represent approximately 2.6% and 7.4%, of the
Issuer's outstanding Common Stock and Limited Vote Common Stock. Upon
conversion, such 3,589,090 shares would represent in the aggregate approximately
9.7% of the Issuer's outstanding Common Stock. The foregoing percentage
ownership calculations are calculated in accordance with Rule 13(d)3(d)(1)(i)(D)
and assume that 33,557,271 shares of Common Stock are actually outstanding, as
reported as of November 11, 1999 by the Issuer on its Form 10-Q filed November
15, 1999, as well as all shares issuable upon conversion of the relevant
Convertible Notes.

Enron may be deemed to beneficially own the shares of Common Stock
issuable upon conversion of the Convertible Notes held by both Thunderbird and
JEDI II, and ENA may be deemed to beneficially own the shares of Common Stock
issuable upon conversion of the Convertible Notes held by JEDI II; however,
Enron and ENA each disclaim beneficial ownership over such securities. Further,
Thunderbird has disclaimed beneficial ownership over the shares of Common Stock
issuable upon conversion of the Convertible Note held by JEDI II, and JEDI II
disclaims beneficial ownership over the shares of Common Stock issuable upon
conversion of the Convertible Note held by Thunderbird.

Enron and Thunderbird may be deemed to share voting and dispositive
power over the shares of Common Stock issuable upon conversion of the
Convertible Note held by Thunderbird. Enron, ENA and JEDI II may be deemed to
share voting and dispositive power over the shares of Common Stock issuable upon
conversion of the Convertible Note held by JEDI II. The filing of this statement
on Schedule 13D/A shall not be construed as an admission that Enron, ENA, JEDI
II or any person listed on the Schedules hereto is, for the purposes of Section
13(d) or 13(g) of the Act, the beneficial owner of any securities covered by
this statement. Other than the transactions described herein, none of the
Reporting Entities, nor to their knowledge any of the persons named in the
Schedules hereto, has effected any transaction in the Common Stock during the
preceding sixty days.

ITEM 7. MATERIAL TO BE FILED AS EXHIBITS.

(i) Purchase and Sale Agreement dated as of December 21, 1999

(ii) Partial Assignment and Assumption Agreement dated as of
December 21, 1999
