Patriots Plaza II and III, located in the heart of Southwest Washington, DC, have been awarded LEED Core & Shell Gold Certification, making them part of the largest speculative office project in the District to receive a LEED Gold rating. Haynes Whaley’s engineers collaborated with the project team, including Trammell Crow Company, Gensler, B&A Consulting Engineers, and Helix Constructors, to design a facility that meets new government security standards, is marketable to private sector tenants, minimizes the impact to the environment and is energy efficient. Patriots Plaza II and III perform 14% better than ASHRAE 9.1, utilized over 20% of recyclable and regional building materials, and recycled more than 80% of the construction waste.

Patriots Plaza is a three-phase, 1 million sf office complex that is more than 80% leased by the General Services Administration for multiple U.S. Government agencies, including the FBI, FEMA, Health and Human Services, and the U.S. Department of Agriculture. Our engineers provided structural design services for the entire complex, which was the first market-driven urban complex designed to meet post 9/11 security standards for a Level IV facility. Patriots Plaza’s high security features include progressive collapse avoidance, a hardened structure to resist blast loading, special column designs in the below-grade parking garage, and intricate detailing of reinforcement to increase the ability of the structure to confine damage and withstand attack.

Haynes Whaley was the engineer of record for the project which also included Developer: Trammell Crow Company; Architect: SmithGroup; and Contractor: Clark Construction.
