The logistics subsidiary of Emery Worldwide plans to build a 100,000-square- foot warehouse next to the air freight carrier's hub in Dayton, Ohio.

Randy Clark, executive director for Logistics Worldwide, said Friday that the Emery unit hopes to receive approval from the Dayton city govern- ment in early September, enabling construction to begin in October. The facility should be completed by the end of March.The new warehouse is designed to serve large customers, Mr. Clark said. Smaller custom- ers store parts at the hub itself, but that facility lacks the space to handle large volumes.

Logistics Worldwide, whose clients include 3 Com, Motorola and Baxter Healthcare, eventually plans to have many warehouses at the Dayton hub, Mr. Clark said, adding "We're taking it one step at a time."

The U.S. expansion follows the June 1 opening of a new warehouse in Singapore to serve multinational customers in Asia such as Facit AB, a Swedish manufacturer and distributor of electric typewriters and copiers, and Liebert Far East, a manufacturer of industrial air conditioners and uninterruptible power supplies.

The Palo Alto, Calif. company, formed in December 1993, also intends to build a multiuser warehouse in Amsterdam to serve its customers' European distribution needs, said Mr. Clark, a 13-year Emery veteran who assumed his present position in February.

No dates have been set for the Amsterdam facility.

Under a contract with Iomega, a Roy, Utah, manufacturer of computer memory storage devices, Logistics Worldwide is managing Iomega's European distribution, including the operation of a warehouse that opened Aug. 1 in Frankfurt.

"We're an integral part of their logistics chain," said John Boner, a global account executive in Salt Lake City for Emery, which has developed North American import and export programs for Iomega over the past two years.

The Frankfurt contract should be worth some $2 million in annual revenue for Logistics Worldwide. It said Iomega decided to outsource its European logistics for a variety of reasons, including a desire to concentrate on its core competency in manufacturing and marketing.

The deal will enable Iomega to take advantage of the latest development in warehouse automation and expertise, along with the new distribution opportunities stemming from Europe's growing economic integration, Logistics Worldwide said.

The Emery unit also operates the perishables and equine center at Hartsfield International Airport in Atlanta. It claims that the center had been losing money until Logistics Worldwide took it over on March 1 and that it's now making money.

The company also operates a 45,000-square-foot export warehouse in Wood Dale, Ill., for Motorola's Land Mobile division. Logistics Worldwide developed a warehouse and inventory management system that supports the consolidation operation.

Mr. Clark said he did not have figures on the unit's annual revenue

because of accounting complexities in separating its business from that of Emery, itself a subsidiary of Consolidated Freightways Inc.

Logistics Worldwide works closely with Menlo Logistics, another CF subsidiary. Menlo's business is concentrated in North America, whereas Logistics Worldwide has an international focus, Mr. Clark said.
