REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Plan Administrator of the
Chicago Bridge & Iron Savings Plan:

We have audited the accompanying statements of net assets available for benefits
of the Chicago Bridge & Iron Savings Plan (the "Plan") as of December 31, 2003
and 2002, and the related statement of changes in net assets available for
benefits for the year ended December 31, 2003. These financial statements are
the responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States) and in accordance with generally
accepted auditing standards as established by the Auditing Standards Board
(United States). 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 provides a reasonable basis for our
opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan as of December 31,
2003 and 2002, and the changes in net assets available for benefits for the year
then ended December 31, 2003 in conformity with accounting principles generally
accepted in the United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule, listed on the
Table of Contents, is presented for the purpose of additional analysis and is
not a required part of the basic financial statements, but is 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. This schedule is the responsibility of the Plan's management. This
schedule has been subjected to the auditing procedures applied in our audit of
the basic 2003 financial statements and, in our opinion, are fairly stated in
all material respects when considered in relation to the basic financial
statements taken as a whole.

CHICAGO BRIDGE & IRON SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS AND SUPPLEMENTAL SCHEDULES
DECEMBER 31, 2003 AND 2002
-------------------------------------------------------------------------------

1.    DESCRIPTION OF THE PLAN AND INVESTMENT PROGRAM

      The following describes the major provisions of the Chicago Bridge & Iron
      Savings Plan (the "Plan") and provides only general information.
      Participants should refer to the Plan document for a more complete
      description of the Plan's provisions.

      GENERAL--The Plan is a defined contribution plan in which designated
      employees of Chicago Bridge & Iron Company and certain of its wholly owned
      subsidiaries (the "Company") are eligible to participate. The Plan is
      subject to the provisions of the Employee Retirement Income Security Act
      of 1974 ("ERISA").

      T. Rowe Price Trust Company (the "Trustee") serves as trustee. The record
      keeper for the Plan, under a contract with the Company, is T. Rowe Price
      Retirement Plan Services, Inc. ("RPS").

      MERGERS INTO PLAN--Effective January 1, 2002, the Morse Construction Group
      division of the Rock-Mo 401(k) Plan merged into this plan. Participant
      account balances of $629,122 were transferred to the Plan during 2002.

      Effective October 3, 2002, the CB&I Shop Employees 401(k) Plan merged into
      this Plan. Participant account balances of $4,209,491 were transferred to
      the Plan during 2002.

      Effective December 31, 2000, the Howe-Baker Engineers, Inc. Employees'
      Profit-Sharing 401(k) Plan, Matrix Engineering, Inc. Savings Plan, A&B
      Buildings, Inc. Savings Plan and Callidus Technologies 401(k) Savings Plan
      ("Merged Plans"), merged into this Plan.

      PARTICIPANT AND COMPANY CONTRIBUTIONS--The Plan is a combination
      profit-sharing and 401(k) voluntary salary deferral plan. Except as noted
      below, the Company automatically contributes 5% of annual pay (including
      overtime and incentive compensation) and may contribute up to 12%
      depending on Company performance and IRS limits on compensation. The
      Company contribution is applicable for each eligible participant following
      the end of the Plan year for which the contribution is made. Participants
      may contribute amounts on a pretax deferred basis from a minimum of 1% to
      a maximum of 75% of compensation subject to the dollar limits set by the
      IRS, or lower percentage limits set by the Company in advance of a given
      Plan year. Participants may elect to change their contribution percentages
      at any time in advance of the next payroll period.

      The Company contributes a dollar-for-dollar match of the participants'
      annual 401(k) contributions, up to the first 3% of the compensation that
      the participant elects to contribute.

      For purposes of contributions, the following applies for participants
      covered by the merged plans:

      o     For participants who formerly participated in the Howe-Baker
            Engineers, Inc. Employees' Profit-Sharing 401(k) Plan, the Company
            contributes 1% of compensation. Additionally the Company makes
            matching contributions of 50% of the first 4% of compensation, and
            may make additional discretionary contributions. A discretionary
            contribution of $1,685,368 was made for the Plan year ended December
            31, 2003.

                                      -4-


      o     For participants who formerly participated in the Matrix
            Engineering, Inc. Savings Plan or the A&B Builders, Inc. Savings
            Plan, the Company makes matching contributions of 50% of the first
            6% of compensation, and may make discretionary contributions as
            determined each year. There were no discretionary contributions
            during the year.

      o     For participants who formerly participated in the Callidus
            Technologies 401(k) Savings Plan, the Company automatically
            contributes 3% of annual pay (including overtime and incentive
            compensation) and may contribute up to 6% depending on Company
            performance and IRS limits on compensation; makes matching
            contributions of 100% of the first 3% of compensation; and may make
            discretionary Company contributions as determined each year. A
            discretionary contribution of $284,027 was made for the Plan year
            ended December 31, 2003.

      o     For participants who formerly participated in the CB&I Shop
            Employees 401(k) Plan, which merged with the Plan during 2002, the
            Company made matching contributions of 100% up to $0.60 per hour for
            total hours worked for Clive and Warren, with matching contributions
            ceasing for Warren employees on November 3, 2002. The Company made
            matching contributions of $0.70 per hour up to October 31, 2002 and
            $0.75 per hour beginning November 1, 2002 for total hours worked for
            Provo employees.

      o     For participants employed by Morse Construction Group who formerly
            participated in the Rock-Mo 401(k) Plan, the Company makes matching
            contributions of 100% of the first 3% of compensation; and may make
            discretionary Company contributions as determined each year. No
            discretionary contribution was made for the Plan year ended December
            31, 2003.

      PARTICIPANT ACCOUNTS--Individual accounts are maintained for each Plan
      participant. Each participant's account is credited with the participant's
      contribution, Company contributions, and allocation of investment earnings
      or losses. Allocations are based on account balances. The benefit to which
      a participant is entitled is the benefit that can be provided from the
      participant's vested account.

      INVESTMENT OPTIONS--Participants direct the investment of their account
      balances into any or all of a number of investment options which include
      mutual funds investing in equities (including the Trade Link investment
      account investing in mutual funds beyond the Trustee's family of funds) a
      company stock fund (which invests in the common stock of Chicago Bridge &
      Iron Company, N.V.), an income fund investing in bonds, a stable value
      fund, and a money market fund.

      The Plan's investments in the common stock of Placer Dome, Inc. and
      Mississippi Chemical Corp. result from prior plan mergers and no future
      investment is permitted in those investments.

      VESTING--Company matching contributions vest 100% after three years and
      the Company's annual contributions vest 100% after five years of service
      with the Company. Participants who terminate their participation in the
      Plan due to retirement, disability, death or work force reduction are
      granted full vesting in Company contributions.

      For participants formerly included in the CB&I Shop Employee 401(k) Plan,
      Company matching contributions prior to 2002 vest over a five-year
      cliff-vesting schedule. Company contributions made in 2002 and 2003 vest
      over a three-year cliff-vesting schedule.

      PARTICIPANT LOANS--Participants may borrow up to 50% of their vested
      account balances, up to $50,000, with a minimum loan amount of $1,000. No
      more than one loan may be outstanding from a participant's account at any
      time. Loans are secured by the balance in the participant's account, bear
      interest at the prime rate plus 1% and are repayable over a period not to
      exceed five years, except for


                                      -5-


      principal residence loans, which are repayable over a period not to exceed
      fifteen years. Any amount borrowed is deducted pro rata from the funds in
      which the participant account is invested. Repayments of principal and
      interest are credited to the funds in which the participant's deferrals
      are invested.

      PAYMENT OF BENEFITS--Upon termination of employment, participants may
      receive a lump-sum payment of their account balances, subject to the
      vesting provisions described above. Other payment forms are available to
      certain participants for accounts existing prior to January 1, 1997.

      FORFEITURES--Forfeited accounts, representing the unvested portion of the
      Company's contributions, were approximately $477,000 and $353,000 as of
      December 31, 2003 and 2002, respectively. These balances will be used to
      reduce future Company contributions. Amounts used in 2003 and 2002,
      respectively, to offset employer contributions totaled $377,413 and
      $420,000.

2.    SUMMARY OF ACCOUNTING POLICIES

      BASIS OF ACCOUNTING--The accompanying financial statements of the Plan
      were prepared on the accrual basis of accounting in accordance with
      accounting principles generally accepted in the United States of America
      ("GAAP").

      USE OF ESTIMATES--The preparation of financial statements in conformity
      with GAAP requires management to make estimates and assumptions that
      affect the reported amounts of assets and liabilities, and changes
      therein, and disclosure of contingent assets and liabilities. Actual
      results could differ from those estimates. The Plan utilizes various
      investment instruments. Investment securities, in general, are exposed to
      various risks, such as interest rate, credit, and overall market
      volatility. Due to the level of risk associated with certain investment
      securities, it is reasonably possible that changes in the values of
      investment securities will occur in the near term and that such changes
      could materially affect the amounts reported in the financial statements.

      INVESTMENT VALUATION AND INCOME RECOGNITION--The Plan's investments are
      stated at fair value as determined by quoted market prices, except for
      investments in the Stable Value Fund, which is stated at contract value
      (which includes accrued interest). Participant loans are valued at cost,
      which approximates fair value. The net appreciation (depreciation) in fair
      value of investment securities consists of the net changes in unrealized
      appreciation (depreciation) in fair value and realized gains (losses) upon
      the sale of investments. The net change in unrealized appreciation
      (depreciation) is determined using the fair values as of the beginning of
      the year or the purchase price if acquired since that time. Realized gains
      (losses) upon sale are calculated using a first-in, first-out basis.

      The T. Rowe Price Stable Value Fund is a common and collective trust
      ("CCT"). The Plan owns shares in this CCT, which, in turn, holds shares in
      the underlying securities, which includes guaranteed investment contracts.
      The fund provides for benefit-responsive withdrawals at contract value.
      The average yield for the CCT was approximately 4.27% for the year ended
      December 31, 2003. The crediting interest rate for the CCT was
      approximately 4.03% and 4.85% at December 31, 2003 and 2002, respectively.

      Purchases and sales of securities are recorded on a trade date basis.
      Interest income is recorded on an accrual basis. Dividend income is
      recorded on the ex-dividend date.

      ADMINISTRATIVE EXPENSES--Trustee fees are paid by the Plan. Investment
      management fees, agent fees and brokerage commissions are paid by the Plan
      and are included as a reduction of the return earned on each fund. Other
      outside professional, administrative services are paid or provided by the
      Company.

                                      -6-


      PAYMENT OF BENEFITS--Benefit payments to participants are recorded upon
