equivalent to a 65,000-pound truck hitting it at 50 mph. Stopping the truck or car dead in its tracks, the DSC501 protects against a “second hit” risk from a second vehicle. The stadium preferred installing these barricades in a more industrial look, wanting them to be seen.
Five retractable DSC720 bollards were used at the pedestrian entry. This is Delta’s highest crash rated bollard, stopping a 15,000 pound vehicle at 50 mph. The bollard will stop and destroy much larger vehicles than those tested at high velocities. The DSC720 is 35 inches tall and 15 inches wide. At Mercedes-Benz Stadium, the bol- lards feature brushed stainless-steel sleeves.
Oftentimes, the ground below the access points are filled with ca- bles, wires, pipes and other infrastructure products. As a result, typi- cal, below ground installed traffic bollards, barriers and barricades cannot be used because these infrastructure products are too close to the surface. The solution is to use surface-mounted and shallow foundation barricades and barriers.
At the same time, for some reason, delivery entrances never seem to be as secured as the main entrances to the stadium. With delivery vehicles coming and going, delivery entrances need a solution that lets delivery vehicles enter and exit but stop unauthorized vehicles from entering at all.
At the loading docks, 39 of Delta’s fastest, smallest and shallow- est foundation barricades were implemented. Chosen especially for high speed applications and ease of installation, the cost effective DSC2000 barrier is K12 crash certified with no penetration, meaning it will stop a 15,000 pound vehicle traveling 50 mph dead in its tracks. The ten-inch shallow foundation also reduces installation complexity, time, materials and corresponding costs.
Lastly, 50 DSC680 shallow foundation fixed bollards with stain- less steel sleeves protect pedestrian areas. They secure any unpro- tected locations where vehicle bombers and errant drivers have no obstacles. Versus cement barriers such as posts and pots, many orga- nizations prefer fixed post bollards for several reasons.
When hit, cement posts and pots can explode, literally spreading shrapnel throughout the crowd, potentially creating numerous inju- ries. Shallow foundation bollards can be installed within sidewalks or on top of concrete deck truss bridges as well as conform to the inclines and turns of a locale. They also meet the one-meter clearance regulations mandated by the Americans with Disabilities Act (ADA).
The fixed bollard, which does not go up and down, provides a sig- nificant blocking device solution that continues to challenge security directors faced with threats such as stopping a vehicle from plowing into the stadiums inner perimeter. They let facility managers meet a long-standing challenge—how to easily install bollards on shallow substrates, including those that are not level or have turns. No longer do locations, such as curves on hills, the upper levels of parking struc- tures and other unprotected locales have to rely on unsightly “make- do” solutions to stop car bombers or wayward drivers.
“Delayed by roof issues, the Mercedes-Benz Stadium challenged us with a condensed schedule to provide one of the world’s most se- cure vehicle access systems,” Martina said. “I’m proud to say that our team completed the work on time and walked away from the project with another pleased client.”
This isn’t the only stadium using Delta equipment to protect staff and attendees from vehicle harm. Among many, Penn State and Purdue as well as Levi Stadium in San Francisco (49ers) are well- known users. Unfortunately, most procurement offices won’t vendors announce their purchases. This is too bad since terrorists typically won’t go where they know barricades are deployed, reducing security risks dramatically.
Leading universities, including six of the Associated Press (AP) top-10 rated 2018 pre-season football schools, also stayed one step ahead of terrorists and errant drivers this year on their campuses by identifying vulnerable areas and securing them within minutes with Delta MP5000 temporary, portable barriers. These mobile deployable vehicle crash barriers carry a K8 rating (M40 ASTM rating), stop- ping 7.5 ton vehicles traveling 40 mph.
Terrorists typically don’t go where they see barricades, so plac- ing them wherever possible attacks can happen reduces security risks dramatically. Today, there is little excuse for a major stadium to suffer an attack which uses a vehicle to break through
the perimeter. Whatever the weakness a terrorist
thinks can be exploited, there is a type of bollard,
barricade or barrier to stop him, yet let autho-
rized people through.
