UNICCO To Provide Integrated Operating Services For CarrAmerica Washington, D.C. Properties.

Business Editors

UNICCO(R) Service Company, one of North America's largest integrated facilities services outsourcing companies, has been selected by CarrAmerica Realty Corporation (NYSE:CRE) to provide integrated operating services for ten Washington, D.C. properties. CarrAmerica, an office property owner, developer, and operator, is one of the country's leading real estate investments trusts (REITs) with properties in 12 key markets across the United States.

CarrAmerica selected UNICCO to provide bundled services and manage several subcontractors to give CarrAmerica managers a single point of contact for all building services. The contract is being implemented in three phases with UNICCO beginning immediately at five properties and ultimately extending to 3.5 million square feet at five additional sites west of the White House. The first five properties are: 1700, 1717, 1730, 1747 and 1775 Pennsylvania Avenue.

Commented Joe Donovan, CarrAmerica vice president/director of operations, "We've been seeking a world-class operating services outsourcing partner that can effectively coordinate the day-to-day operations of several subcontractors -- a company that understands our commercial building management business and also has the management depth to direct other vendors. UNICCO has demonstrated that expertise. We look forward to developing a close working relationship with the UNICCO team."

UNICCO will be applying some of its latest management technology, including palmtops for automated inspections, advanced time management systems, eProcurement and Electronic Data Interchange (EDI) electronic billing. The company will also utilize InfoCentre, a Web-based operations and issues management platform in use by CarrAmerica throughout its managed portfolio. UNICCO will receive tenant work order requests through an 800 number or over the Internet from the CarrAmerica InfoCentre call center. UNICCO personnel will then instantly receive new work orders through their wireless handheld devices and use the same Internet-based capability to close out the work orders as soon as they are completed.

"CarrAmerica is a sophisticated, technologically advanced property manager that is constantly searching for better ways to do things," commented David Giamichael, vice president, operations for UNICCO. "This fits perfectly with UNICCO's commitment to couple our integrated operating management knowledge with technology. Marrying our service management technology with CarrAmerica's building management technology creates a comprehensive operating network that delivers outstanding service to all tenants."
