Corporate Office Properties Trust of Columbia has been selected to build county offices and a courthouse at the campus off Rogers Avenue in Ellicott City.

The company was chosen from three finalists to develop a preliminary design and more detailed cost estimate for the project, said Jim Vannoy, an assistant to the County Executive James N. Robey (D).

The deal is not yet final.

If the county can't come to terms on a price, it may go to one of the other finalists, which include Trammell Crow Co. and Lerner Enterprises.

Randal M. Griffin, president of Corporate Office, said the deal is worth about $100 million and could save the county money if buildings are consolidated as proposed. Also, the cost of operating new buildings is cheaper, he said.

Corporate Office, a real estate investment trust, buys, builds and manages suburban office parks for government and other tenants.

Motorcycle Museum in Jessup

There's a new museum for motorcycle enthusiasts.

A 1,000-square-foot portion of Bob's BMW Motorcycles in Jessup is now devoted to about 30 mostly vintage and classic BMW motorcycles plus memorabilia that owner Bob Henig has collected.

The Maryland Department of Business and Economic Development designated the site a museum and tourist attraction in July, and Henig held a dedication ceremony last month, he said.

The state designation allows the Vintage Museum to offer brochures at all Maryland visitors centers. Henig plans to post signs on major roadways directing drivers to the museum.

"As my business and my interest and exposure to BMW grew, I began to collect a motorcycle here and a motorcycle there, and I acquired the inventories of dealers that have long since gone out of business," Henig said. "I acquired enough of this stuff to be able to transfer it from a personal hobby to something I can share with my customers."

In addition to the 30 motorcycles on display, Henig has 10 or 12 others that he will rotate in and out of the exhibit, he said.

Henig's store opened in 1981 in Wheaton as a used parts and accessories shop specializing in BMW motorcycles. The store evolved into a dealership that sells and services new BMW motorcycles as well as used, reconditioned and restored BMWs. The store has been at 10720 Guilford Rd. for nearly seven years.

Henig said the free museum is open to the public six days a week.
