Camden Yard Rehabilitation

Location: Baltimore, Maryland

Size: 430,000 square feet (warehouse) 132,000 square feet (station)

JMA Preservation provided complete architectural services for the exterior envelope restoration of the historic B&O Warehouse and Camden Station, both landmark railroad structures located at the site of the historic Camden Railroad Yard. The Warehouse is the outfield backdrop for the Camden Yard ballpark built by the Baltimore Orioles built in 1992.

Camden Station was constructed between 1856 and 1867 as the largest passenger terminal in America. This historic Italianate style station was the site of the Pratt Street riots, and a stop on Lincoln's funeral train. The building now houses the Sport's Legends Museum and the Geppi Entertainment Museum.

The massive, eight-story B&O Warehouse was built in 1899 adjacent to the B&O's Camden Station and the freight yard. At 1,116 feet long it is reputed to be the longest building east of the Mississippi River and was designed to hold 1,000 carloads of freight at one time. The Warehouse was rehabilitated in 1991 and is the location of the Orioles' front offices and also holds numerous shops, restaurants and offices in its 430,000 square feet.

JMA Preservation conducted a detailed condition assessment of the roof and masonry walls. Our research lead to the discovery of documents at the National Archives leading to a better understanding of the original materials, lost features and adjoining structures. We recommended and designed the reincorporation of the lost features and gave the needed guidance on conservation of the original materials in place. Using information from the condition assessment, the JMA Preservation team prepared construction documents for restoration of the masonry walls and the correction of moisture problems below grade. The roof was replaced and miscellaneous repairs were included. The JMA Preservation conservators undertook a mortar analysis and developed a mortar mix design. JMA Preservation was responsible for overseeing the $6.5 million construction project on behalf of the Maryland Stadium Authority. Construction work was by Coakley Williams Construction, Inc. The project was completed within budget and on a tight schedule dictated by the baseball season and the Orioles' home schedule.
