                  The filing of this statement on Schedule 13D by the Quanta
Services, Inc. Stock Employee Compensation Trust (the "Trust") does not
constitute, and should not be construed as, an admission that Wachovia Bank,
N.A., as trustee of the Trust (the "Trustee"), beneficially owns any securities
covered by this Statement or is required to file this Statement. In this
connection, the Trustee disclaims beneficial ownership of the securities covered
by this Statement.

Item 1.           Security and Issuer.
                  -------------------

                  The class of equity securities to which this Statement relates
is the Common Stock, $.00001 par value (the "Common Stock"), of Quanta Services,
Inc., a Delaware corporation (the "Issuer"). The principal executive offices of
the Issuer are located at 1360 Post Oak Blvd., Suite 2100, Houston, Texas 77056.

Item 2.       Identity and Background.
              -----------------------

                  This Statement is being filed by the Trust. The business
address of the Trust is c/o Wachovia Bank, N.A., 101 North Main Street,
Winston-Salem, North Carolina 27150. The address of the Trustee is 101 North
Main Street, Winston-Salem, North Carolina 27150. The Trust is a trust organized
under the laws of the State of Delaware. The Trustee is a national banking
association organized under the laws of the United States.

                  During the last five years, neither the Trust nor the Trustee
has been (a) convicted in a criminal proceeding (excluding traffic violations or
similar misdemeanors) or (b) a party to a civil proceeding before a judicial or
administrative body of competent jurisdiction as a result of which proceeding
such person is or was subject to a judgment, decree or final order enjoining
future violations of, or prohibiting or mandating activities subject to, federal
or state securities laws or finding any violation with respect to such laws.

Item 3.       Source and Amount of Funds or Other Consideration.
              -------------------------------------------------

                   On March 13, 2002, the Issuer and the Trustee, as trustee for
the Trust, entered into a trust agreement, pursuant to which the parties
established the Trust. Pursuant to a related Common Stock Purchase Agreement,
dated March 13, 2002, between the Issuer and the Trustee, as trustee, the Issuer
sold eight million shares of Common Stock to the Trust in exchange for a
promissory note in the amount of $132,079,929.86 (the "Note") and a cash amount
equal to $70.14, the aggregate par value of shares being newly issued and sold
to the Trust. The Note bears interest at the rate of 6.50% per annum and is
payable in quarterly installments through January 1, 2017. Principal and
interest on the Note are expected to be repaid through contributions to the
Trust by the Issuer and dividends received on the shares of Common Stock issued
to the Trust.

                                      -3-




Item 4.       Purpose of Transaction.
              ----------------------

                  The Issuer has advised the Trustee that the Trust was created
to fund the Issuer's obligations during the term of the Trust in respect of
certain of the Issuer's benefit plans such as its employee stock purchase plan
and stock incentive plan. The Trust will release the Common Stock over the life
of the Trust, as the Note is paid down through contributions by the Issuer, to
satisfy certain benefit requirements of the Issuer's benefit plans. Through the
Trust, the Issuer's employees would receive an ownership interest in the Issuer.
The Issuer has advised the Trustee that by transferring stock to the Trust, the
Issuer is demonstrating its ongoing commitment to its employees and to the
benefit plans funded by the Trust. The Issuer has advised the Trustee that
compensation expense will be recognized by the Issuer based on the fair value of
the shares as they are released from the Trust, and that unallocated shares held
by the Trust will effectively not be included in calculating the Issuer's
earnings per share. The Issuer also has advised the Trustee that the
implementation of the Trust should enhance the Issuer's equity position from a
rating agency perspective and thereby create additional financial flexibility in
the future.

                  The Trust Agreement contains confidential pass-through voting
and tendering provisions that are structured such that participants in the
Issuer's broad-based employee stock purchase plan determine the manner in which
stock held by the Trustee under the Trust is voted and tendered (except that
participants in the Issuer's employee stock purchase plan who are directors of
the Issuer will not be included in determining the pass-through voting and
tendering decisions). The Trust will terminate in the event of a change in
control (as defined in the Trust Agreement), and if at that time the value of
the Common Stock in the Trust exceeds the sum of any obligations then pending
under the applicable benefit plans and the remaining principal of plus any
accrued interest on the Note, the excess will inure to the benefit of a broad
group of employees. A "change of control" is generally defined to include (1) an
acquisition by any person or group, aside from any acquisition by or directly
from the Issuer or by an employee benefit plan or trust of the Issuer, of 75% of
the total number of outstanding shares of the Common Stock (on an as converted
basis and assuming full exercise of all outstanding rights, options and
warrants), except for any transaction following which the existing stockholders
own more than 25% of the voting securities of the entity surviving the
transaction or in which the sole consideration to stockholders in the
transaction is publicly traded common stock; or (2) a dissolution, liquidation,
or sale of substantially all the Issuer's assets, or a business combination,
except for a business combination following which the existing stockholders of
the Issuer own more than 25% of the surviving entity (or the entity controlling
such surviving entity) in substantially the same proportion as they owned
immediately prior thereto or a business combination in which the sole
consideration to stockholders is publicly traded common stock.

                  Except as described above, the Trust has no plans or proposals
which relate to or would have the effect of any of the transactions listed in
Item 4 (a) through (j) of Schedule 13D.

Item 5.       Interest in Securities of the Issuer.
              ------------------------------------

                  As of March 20, 2002, the Trust held 8,000,000 shares of
Common Stock, which represented approximately 11.77% of the Company's
outstanding shares of Common Stock or


                                      -4-




9.39% of the voting power with respect to the Common Stock on that date (1)
and as to which the Trust may be deemed to have shared voting and dispositive
power. The shares will be allocated during the course of the year or in
following years as provided in the Trust Agreement. The Issuer has advised the
Trustee that the Issuer's contributions to the plans, as defined in the Trust
Agreement ("Plans"), will be decreased by the value of the shares allocated to
the Plans from the Trust. The filing of this Statement on Schedule 13D by the
Trust does not constitute, and should not be construed as, an admission that the
Trustee beneficially owns any securities covered by this Statement or is
required to file this Statement. In this connection, the Trustee disclaims
beneficial ownership of the securities covered by this Statement.

Item 6.       Contracts, Arrangements, Understandings or Relationships with
              -------------------------------------------------------------
              Respect to Securities of the Issuer.
              ------------------------------------


                  The Issuer and the Trustee, as trustee for the Trust, have
entered into the Trust Agreement and the Common Stock Purchase Agreement, and
the Trustee, as trustee for the Trust, has issued the Note to the Issuer. The
Trust Agreement and the Common Stock Purchase Agreement, which includes the form
of Note as an Annex, are exhibits to this Schedule 13D and the description set
forth above is qualified by incorporation thereof.
