ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS.

     On August 4, 1998, a wholly owned subsidiary of Quanta Services,  Inc. (the
"Company") acquired in a single transaction Underground Construction Co., Inc.
and Five Points Construction Company (which entities were affiliates prior to
such acquisition and are collectively referred to as the "Underground
Entities").  The Underground Entities provide specialty contracting services,
such as manhole and conduit installation for the power and telecommunications
industries, industrial and process piping, construction and maintenance of
aircraft fueling systems and heavy engineering projects for passenger rail
systems.  The Company intends to continue such operations.

     The terms of the acquisitions of the Underground Entities were the result
of arms'-length negotiations.  The aggregate consideration for the Underground
Entities consisted of the assumption of certain liabilities, 944,596 shares of
the Company's Common Stock and $19.5 million in cash, which was funded under the
Company's syndicated credit facility, the agent of which is Bank One, Texas, NA.
