Pentagon Reconstruction, “The Phoenix Project”
Arlington, Virginia
Pentagon
Pentagon

Syska Hennessy Group was selected by the Pentagon Renovation Office (PenRen) to participate in the “Phoenix Project”, the reconstruction of 450,000 SF in Wedges 1 and 2 that were damaged by terrorist activity on September 11, 2001. Our firm provided engineering design services for the HVAC, Electrical, Telecommunications and Security systems. This nationally prominent project was designed and constructed in an accelerated manner in order to open for business on 9/11/02.

The entire project was a very interactive, fast track process, and required extensive commitment of personnel overtime and supporting resources. This project was managed in a unique manner to meet the aggressive completion date, while maintaining restrictive document handling procedures (no posting or e-mailing of design documentation among other restrictions) as well as sensitivity to the historical nature of this landmark building.

Syska’s first involvement in the project commenced immediately after the Federal Bureau of Investigation concluded its investigation of the site as a crime scene. Engineers conducted field investigations of existing conditions in the entire area of the Pentagon destroyed as a result of the September 11 attack.

The second phase of this effort commenced in January of 2002, Syska was contracted to perform engineering design services, preparation of contract documentation, and provide construction administration services for HVAC, electrical, security and telecommunications infrastructure for the Wedge 1 portion of the damaged area. This involved the development of comprehensive core and shell contract documents including significant upgrade to the pre-September 11 design to allow for improved flexibility, redundancy, and defensibility.
