Re: Quanta Services, Inc.

Dear Sir/Madam:

The representations made in this letter are based solely on discussion with and
representation from the engagement partner on the audits of the financial
statements of this registrant for the two most recent fiscal years. This
individual is no longer with Arthur Andersen LLP. We have read Item 4 included
in the Form 8-K dated June 28, 2002 of Quanta Services, Inc. (Commission File
Number 1-13831) to be filed with the Securities and Exchange Commission and have
found no basis for disagreement with the statements contained therein.


Very truly yours,


/s/ Arthur Andersen LLP
