Baltimore has a lot of history. Take the B&O Railroad's 1898 Camden Yards warehouse, for example. The eight-story, 1,000- foot-long brick building has 876 brick arched window openings and is a monument to 19th-century brick architecture. It also is located on the same piece of prime downtown property where the Baltimore Orioles decided in 1988 to build their new ballpark. THE WAREHOUSE Some said the warehouse-an abandoned, turn-of-the-centurybuilding that stretched along six blocks on the western edge of the site- had no historical value and should be demolished. But the Orioles felt that preserving and renovating the warehouse would not only add character to the new ballpark, but would minimize the project's impact on the downtown area. A firm specializing in masonry restoration was awarded the contract to chemically clean the warehouse walls, replace damaged and missing brick, and tuckpoint all of the brickwork. THE BALLPARK One construction option originally considered by project architects Hellmuth, Obata & Kassabaum (HOK) Sports Facilities Group of Kansas City, was the use of precast concrete panels. That suggestion met with little enthusiasm. Ultimately, a design featuring reinforced brickwork was suggested and approved. Specifying the size, shape, and quantity of brick needed was relatively easy. The ballpark has 32 brick arches, incorporates over 20 brick shapes and sizes, and contains more than 1 million brick.
