CB&I Supports Development of Renewable Energy Sources.

THE WOODLANDS, Texas -- CB&I (NYSE:CBI) is participating in the growth of renewable energy sources through involvement in both onshore and offshore wind energy projects.

CB&I was recently awarded a contract by one of the world's largest suppliers of wind turbines to fabricate 150 tubular steel support towers for wind turbines that will be installed in wind farms in the western United States. The towers will support 1.5-megawatt wind turbines, which are the largest wind turbines assembled in the United States and the most widely sold and tested megawatt class wind turbines in the world.

The Company's scope includes fabrication, installation of internals and painting of the 80-meter (262.5 ft) towers, which will be manufactured and shipped from CB&I's fabrication plant in Provo, Utah. More than 18,000 tons (16,329.3 metric tons) of steel will be used for the project, which has a 14-month schedule.

In addition to the western U.S. project, CB&I will be working with the same client on two large offshore wind farm developments in the U.K. The projects are due for award in early 2005 and are part of the initial Round 1 licenses granted by the U.K. authorities. If successful, the contractor will supply more than 600 MW of wind energy generation at each site. For these projects, CB&I would draw upon its extensive offshore experience to supply and install everything but the wind turbines, including the turbine foundation support, offshore transformer platforms, offshore inter-array cabling, offshore and onshore export cables and connection into the electric grid.

"We are pleased to participate in these significant renewable energy projects," said Gerald M. Glenn, CB&I's Chairman, President and CEO. "We believe wind energy has the potential to develop into a substantial market for CB&I. We are proud to contribute to the continued advancement of this reliable, non-polluting energy source."
