                   INDEPENDENT AUDITOR'S REPORT
                   ____________________________





To the Plan Administrative Committee of the
   MasTec, Inc. (Formerly Burnup & Sims Inc.)
   Variable Investment Plan

We have audited the accompanying statement of net assets
available for benefits of Mastec, Inc. Variable Investment Plan
(the "Plan") as of December 31, 1993, and the related statement
of changes in net assets available for benefits for the year
ended December 31, 1993.  The financial statements and
supplemental schedules are the responsibility of the Plan's
management.  Our responsibility is to express an opinion on these
financial statements based on our audit.

We conducted our audit in accordance with generally accepted
auditing standards.  Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement.  An
audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An
audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating
the overall financial statement presentation.  We believe that
our audit provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above
present fairly, in all material respects, the net assets
available for benefit of MasTec, Inc. Variable Investment Plan as
of December 31, 1993, and changes in its net assets available for
benefits for the year then ended in conformity with generally
accepted accounting principles.

Our audit of the Plan's financial statements as of and for the
year ended December 31, 1993, was conducted for the purpose of
forming an opinion on the financial statements taken as a whole. 
The supple-mental schedules of assets held for investment
purposes and reportable transactions as of and for the year ended
December 31, 1993, are presented for the purpose of additional

analysis and are not a required part of the basic financial
statements, but are supplementary information required by the
Department of Labor's Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of
1974.  The supplemental schedules have been subjected to the 
auditing procedures applied in the audit of the basic financial 
statements for the year ended December 31, 1993, and, in our opinion, 
are fairly stated in all material respects in relation to the basic 
financial statements taken as a whole.

     NOTE 1 - DESCRIPTION OF THE PLAN

The following description of the MasTec, Inc. (the "Company") Variable
Investment Plan (the "Plan") provides only general information.
Participants should refer to the Plan agreement for a more complete
description of the Plan's provisions.

     General
     _______

The Plan is a defined contribution plan covering all employees of the
Company who are regularly scheduled to perform twenty (20) or more hours
of work per week, who are age twenty-one (21) or older and who have
completed a one-year service period.  It is a qualified cash or deferred
profit-sharing plan within the meaning of Sections 401(a)and 401(k) of
the Internal Revenue Code and is subject to the provisions of the
Employee Retirement Income Security Act of 1974 (ERISA).  The Plan is
administered by the Plan Administrative Committee.

     Contributions
     _____________

Participants may contribute from one percent (1%) up to ten percent
(10%) of their pretax compensation (as defined in the Plan) into any
combination of three (3) funds.  The Company does not make any
contributions to the Plan.

     Participants' Accounts
     ______________________

Each participant's account is credited with the participant's
contribution and an allocation of the Plan's earnings.  Allocations are
based on participant contributions, earnings and account balances, as
defined by the Plan Administrative Committee.  Since all contributions
to this Plan and all interest earned are allocated to individual
participant account, the Plan is not subject to the insurance program
administered by the Pension Benefit Guaranty Corporation.

     Vesting
     -------

Participants are immediately vested in their voluntary contributions and
earnings thereon.






                                                                Page 9 of 16

                           NOTES TO FINANCIAL STATEMENTS


NOTE 1 - DESCRIPTION OF THE PLAN (continued)

     Loans
     _____

Each participant is eligible to obtain a loan after one year of credited
experience in the Plan.  Interest on the loans accrues at a rate selected
by the Plan Administrative Committee which is commensurate with the
interest rates being charged by financial institutions. Participants may
borrow up to 50% of their account balance.  Loans are secured by the
participant account balance.

     Payment of Benefits
     ___________________

On termination of service, a participant will receive payment of the vested
accrued benefit in a single lump sum or the payment can be deferred to
normal retirement age.

     Income Taxes
     ____________

The Internal Revenue Service has determined that the Plan is exempt from
Federal income tax under Section 401(a) and 501(a) of the Internal Revenue
Code ("Code") as an organization described in Section 501(c)(9) of the
Code; accordingly, no provision for income taxes is required.

     NOTE 2 - SUMMARY OF ACCOUNTING POLICIES

     Basis of Accounting
     ___________________

The financial statements of the Plan are prepared on the accrual basis
of accounting.  Investment income is recognized when earned. Contributions
by participants are accrued on the basis of amounts withheld through
payroll deductions.  The investments are stated at fair value on December
31, 1993.  

     Investments
     ___________

The Plan assets are invested in three separate funds:  Guaranteed Income
Fund, Diversified Equity Fund, and Life Insurance Fund.  The Guaranteed
Income Fund guarantees a fixed rate of return on amounts deposited with
it by the Trustee (7.5% at December 31, 1993).  The Diversified Equity
Fund invests in shares of common stock of companies.  The Life Insurance
Fund purchases whole life insurance for the participants on a pre-tax
basis.

     NOTE 2 - SUMMARY OF ACCOUNTING POLICIES (continued)

Although participants may designate the beneficiaries under the policies,
the Plan is the owner of such policies.  The participants may elect to
designate their contribution to one or any combination of funds.  In
addition, see Note 6 regarding other investment options added subsequent to
year end.

On January 1 or July 1 of each year, a participant may change the
election made in a previous period.  The Plan recognizes unrealized
appreciation and depreciation in the fair value of its investments based
on quarterly quoted market prices.  Purchases and sales of investments
are recorded as of the trade date.

     NOTE 3 - FUNDING POLICY

The Company pays the entire costs of operating and managing the Plan. 
While it has not expressed any intention to do so, the Company reserves
the right to discontinue funding such costs and terminate the Plan
subject to the provisions set forth in the Plan and ERISA.

     NOTE 4 - DIFFERENCES BETWEEN AUDITED FINANCIAL STATEMENT AND FORM 5500

 The financial statement realized gain is computed using historical cost. 
 For the year ended December 31, 1993, a gain of $20,451 is included in
 the supplemental schedule of reportable transaction.  As current value
 reporting is required for the Annual Return Report of Employee Benefit
 Plans (Form 5500), assets are revalued at the end of each plan year and
 such revalued cost is the basis for determining the gain or loss.  Form
 5500 for the year ending December 31, 1993, includes realized gain of
 $2,019, which was computed using the revalued cost basis.

     NOTE 5 - SUBSEQUENT EVENTS

 On March 11, 1994, Burnup & Sims Inc. changed its name to MasTec, Inc.
 and the name of the Plan to Mastec Variable Investment Plan.  On August
 1, 1994, the Plan's name was further amended (effective June 17, 1994)
 to Mastec, Inc. 401(K) Retirement Savings Plan.
