Advised by Homeland Security of their status as a potential terrorist target, Computer Sciences Corporation’s Board of Directors decided to make major upgrades to security at their El Segundo campus—a complex of three buildings totaling 120,000 sf. This project presented Interscape with a series of interesting and critically important challenges.
THE CLIENT RELATIONSHIP
Interscape was engaged during the conceptual planning process and played a major role in analyzing the various construction options and provided value engineering for all of the plans under consideration.
The existing campus had two unrestricted vehicle entrances with no physical protection on any side. Security consultants determined that a vehicle bomb was the most likely threat, and physical intrusion by armed terrorists would be the next most likely risk.
Careful study of Department of Defense methods and standards revealed that if an explosive-laden vehicle could be kept a certain distance from the buildings, the impact of an explosion could be minimized. The building was set back far from the street to provide that distance, and the installation of a high security DOD fence would prevent vehicle penetration. However, interior driveways required installation of blast walls, in the event that a terrorist vehicle gained access to the interior.
Vehicle ingress had to be restricted to one tightly controlled entrance but, for emergency purposes, two means of egress had to be maintained. New interior traffic patterns and controls demanded reorientation of all parking lots, drives, landscaping and site drainage.
In addition, because the facility housed the CSC’s west coast computer systems a self-sufficient emergency power system was required to maintain stand-alone operation for up to 72 hours.
Over a six month period, Interscape implemented the following improvements, in multiple phases, to avoid interruption of corporate operations:
• Reorientation of site access, achieved by creating a median cut with a left turn lane on Continental Blvd. This included paving, striping, landscaping, underground utilities and street lighting, as well as the relocation of an Edison vault.
• Expanding the Continental Blvd. entrance with two ingress lanes (for traffic stacking), security gates, traffic controls and a bullet proof, all-weather guard booth with security systems including cameras, sensors and communications.
• Installation of a perimeter fence to DOD standards, designed to stop a 10,000 lb. vehicle traveling 50 MPH.
• Construction of interior walls that exceed the DOD standard, to help redirect a potential blast upward.
• Expansion and relocation of site lighting, coordinated with a vastly expanded camera system that provides security personnel views of all campus areas, day and night.
• Installation of hydraulically operated bollards in the interior driveways, to control traffic access, while providing instant egress in the event of an emergency and immediate access for emergency equipment.
• Implementation of a 1563 KVA generator, 1600 to 2000 AMP transfer switches in each building, distribution panels and UPS systems to provide all buildings with emergency power for mission-critical systems. This included hundreds of feet of exterior trenching and penetration of existing foundations and slabs to install the required equipment. Final installation and activation took place over holiday weekends to avoid impact to ongoing operations.
• To complete the renovation, new parking lots, driveways, curbs, gutters, walkways, site drainage, irrigation, signage and landscaping were installed. Special lithocrete was used for main walkways, and all landscaping was designed to maintain maximum visibility for security personnel and cameras.
• A new black granite sign was installed at the corner of Continental and Grand.
