Client Objectives

The DOS needed building operations and maintenance services for four facilities: the Harry S. Truman (HST) Building, the nearby Columbia Plaza Complex, the International Chancery Center (ICC), and Blair House. These key Department of State facilities are among the most challenging building management sites in the world.

  • The 2.5 million square-foot HST Building, which houses the DOS headquarters, contains the offices of the U.S. Secretary of State and 24-hour mission-critical areas
  • The Columbia Plaza Complex, the next-largest complex, houses diplomatic security, the main passport office, and a full medical clinic
  • The ICC houses diplomatic administrative functions and maintains a 24x7 special police force
  • Blair House, the official guest residence of the United States, is a historically and politically significant structure with special architectural, technical, and security needs

The mechanical, HVAC, electrical, energy management, and building control systems and equipment in these facilities must operate continuously and efficiently to support U.S. foreign policy functions.


As part of this endeavor, EGS delivered a wide variety of project solutions through the execution of work broadly pertaining to facilities management and operations, including:

  • Focusing on redundancy in order to ensure efficient operations
  • Utilizing a cutting-edge status reporting system to prioritize work and track job progress
  • Maintaining and testing backup systems as well as partnering with specialty electrical subcontractors in order to prevent power outages
  • Rapid response to emergencies and issues as they arise, helping to ensure that communications to overseas posts are not disrupted
  • Preserving the historic integrity and protecting the diplomatic function of the DOS’s structures
  • Daily collaboration between EGS Quality Assurance teams and DOS counterparts to randomly review service calls and scheduled work, identify problems, and find solutions to any issues that arise
  • Exceeding contractual staffing requirements, in both number and qualifications of EGS employees
