58 • DECEMBER 2011 • WORLD FENCE NEWS September 11 Memorial fencing project inspires poignant reflection continued from page 1 consists of the Stalwart anti-ram bar- rier integrated with the Aegis II fenc- ing product. Kenneth White, Ameristar's Exec- utive Director of Perimeter Security Systems, inserts this poignant note: "On a personal level, I am proud to be associated with this project. Doug Karpiloff, the director of security and life safety at the World Trade Center towers, was killed in the terrorist at- tack on September 11, 2001. I knew Doug, having met him after a presen- tation he gave at a seminar hosted by the American Society for Industrial Security (ASIS). I have no doubt that many of the survivors of this tragic event were saved in part due to the products installed and the procedures implemented by Doug at the twin tow- ers that are now memorialized by this site. My mission at Ameristar is to pro- tect the critical infrastructure of our nation. This project reaffirmed my mission on a personal level, and I strive to continue honoring Doug's legacy." Added Security Fence Systems owner Jerry Capano: "We were fortu- nate and honored to be a part of this very special project. It was challeng- ing, but we tackled the issues as they arose." One technical aspect that was en- countered is that there is a sloping grade at the site, but this was easily ac- commodated by the Stalwart II system, as it can rack up to 30 degrees and still function properly, White said. The anti-ram components are housed in the Stalwart framework along the entire fence line, ensuring that any vehicle impact will always engage the anti-ram components at the proper heights. As for the aesthetic re- quirements, it was deter- mined that the Aegis II fence best suited the need for a "low profile, friendly fence" that would wel- come visitors to the memo- rial, while maintaining access control to the site. Anchoring the system are massive concrete footings, with extensive rebar cages. Integrated bollards are spaced throughout the system, anchoring the anti-ram components. I-beam posts serve as intermediary posts. The Aegis II fence panels are affixed to the bol- lards and I-beam posts and the anti- ram components run between the bollards and through the posts in each of the rails. White noted that since the system includes deep footings, the contractor encountered installation challenges when they ran into the foundation of the Deutsche Bank building that stood on the property but had to be taken down floor by floor because it was contaminated during the 9/11 terrorist attacks. The existence of the building's foundation required portions of it to be removed so that the bollard footing could be poured per specification, he noted. Bidding and specification assis- tance began in April of 2011, and the actual installation began in early Au- gust. The project was commissioned on August 24. Once the specification was written, the project was put out to bid and awarded to Security Fence Systems, one of several qualified con- tractors, said White. "My next involvement was to en- sure that the Stalwart II system was in- stalled per specifications. Security Fence Systems had previously in- stalled the Stalwart system at another site, and had proven to be a very com- petent and professional installer," he said. Some issues regarding the bollard post footings and underground utilities arose during the installation, which is not uncommon at urban sites, White added. These issues were quickly ad- dressed and resolved by Ameristar in consultation with their third party test engineer. "In August 2011, Cliff Goodman, Ameristar's market developer for New York, and I were on-site with Security Fence Systems and the Port Authority of New York and New Jersey to vali- date that the Stalwart bollard posts and I-beam posts had the proper footings The photo abo rails whic war t II barrier sho efficientl ve of the non-pub s the cab w h are positioned at the pr y stop a speeding vehic le reinf lic side of the Stal- ced C-c o oper le r le . vel to most h annel contin ued on pa g e 66
