WASHINGTON — The Bush administration said yesterday it would boost the number of contracts given to small and minority-owned businesses for Hurricane Katrina cleanup work, calling the amount now awarded too low.

The Federal Emergency Management Agency said it would set aside an allotment for disadvantaged businesses following its announcement last week that it would rebid millions of dollars in contracts handed out with little or no competition.

The initial $100 million contracts to be rebid were given to four major construction firms — Shaw Group Inc., Bechtel Corp., CH2M Hill Inc. and Fluor Corp. — which had prior relationships with the government.

The Commerce Department, meanwhile, announced a new information center and Web site to help smaller, disadvantaged firms get information about how to competitively bid for Katrina contracts.

The move follows criticism in recent weeks by minority businesses who said they were paying the price for the decision by Congress and the Bush administration to waive competition rules for many of the larger recovery contracts.

About 1.5 percent of the $1.6 billion awarded by the Federal Emergency Management Agency has gone to minority businesses, less than a third of the 5 percent normally required.

"This administration is reaching out to companies of all sizes, especially minority-owned enterprises, to guarantee that those seeking to join the rebuilding efforts can navigate federal agencies and bid for contracts with ease," said Commerce Secretary Carlos M. Gutierrez.

"We're looking to improve to make participation stronger," Gutierrez said. He said that would include the setting of numerical targets for minority participation, although a specific number had not yet been set.

Bush's domestic policy adviser, Claude Allen, said the president gets briefed weekly on the contracts being awarded, with a particular focus on how many are going to small businesses and minority-owned businesses.

"Frankly, the president has not been satisfied. None of us have been satisfied," Allen said in an interview with American Urban Radio Networks. He said Bush wants more people from the hurricane region and more minorities and small businesses to be put to work there.

"We are making changes that will increase the opportunity," Allen said.

Under the procedures detailed yesterday by FEMA, federal officials will solicit competitive bids for remaining Katrina work. Contracts will be for five years, with preference given to small and minority-owned businesses.

"We will now use competitive strategies everywhere possible — placing priority on the use of local and small disadvantaged businesses — as we move into the long-term recovery phase," said Acting FEMA Director David Paulison.

Those businesses can register to receive information on Katrina contracts at the Commerce Department's Hurricane Contracting Information Center at www.rebuildingthegulfcoast .gov. Businesses can also call the center at (888) 487-2362 for help navigating the bidding process.

Rep. Bennie Thompson, D-Miss., praised the moves but expressed concern that FEMA's pledge to boost minority contracting lacked detail.

He asked Paulison in a letter to specify whether FEMA also intends to push for restoring affirmative action rules for contractors and reinstating a "prevailing wage" law. Some believe the suspension of that law has hurt the disproportionately large number of black hourly workers in the region.

"I am glad that the Federal Emergency Management Agency has recognized the problems with its contracting methods," wrote Thompson, a member of the Congressional Black Caucus.
