Security Bollards
(28)
A crash test of Delta Scientific's new DSC720-1M bollards, created to stop taller trucks such as those found in Europe and the Mideast from tumbling over anti-terrorist crash-proof bollards, stopped a 15,000 pound (66.7 Km) flatbed truck impacting at 50 miles per hour (80 kph) with a -0.5 meter penetration of the vehicle, creating an M50, P1 ASTM rating. The bollards caused severe damage to the engine and drive train. This is the type of stopping power customers want for ASTM 50 and K12 rated bollards. Importantly, these taller bollards provide the same type of stopping power as their predecessor, the DSC720, which is installed throughout the world. DSC720 bollards are deployed at U.S. locales, including Federal buildings and Department of Defense installations, as well as at various nations’ embassies and high profile, high-risk facilities, such as Buckingham Palace and the Singapore Parliament, throughout the world. The new bollards feature a variety of power options including Delta’s hydraulic power unit (HPU), all-weather pneumatic, electro-mechanical, manual or fixed post. The DSC720-1M’s controls feature touch screen panels, data logging and Cat 5 cable connections with options of control via a closed network, the Internet, fibre optic or remote operation. Decorative castings and brushed stainless steel sleeves are standard options.

Virtually unlimited in styles and aesthetics, safety consultants can specify having ornamental steel trim attached directly to the Delta Scientific DSC800 decorative bollard or select cast aluminium, iron or bronze to slip over the crash tube. If damaged, one simply slides off the old sleeve and slips on a new one. The designer bollards are available in stainless steel, cast stone, ceramics and epoxy based stones. They can be fitted with an internal warning light for increased visibility and engineered to suit high traffic volumes. These decorative bollards come in six different series – traditional, silhouette, sculptured, omni, lineas and architect. Protection levels all meet or exceed U.S. Department of Defense and Department of State certifications. They hold the highest ratings ever given to bollard systems. The DSC800 is certified at K4, L2, and able to stop a 6,800 kg vehicle at 50 kph. DSC800 bollards are used to protect important facilities from Windsor Castle to a hundred-plus embassies, the Ronald Reagan Library and major government buildings around the world.

Bollards - Expert commentary
Public spaces in cities and suburbs are important places for community development and promoting outdoor recreation. These areas may include main streets, parks, promenades, band shells and fields. Such locations are often utilised by public event planners for community activities, including summer festivals, wintertime ice skating rink installations, music concerts and art fairs. As the year drew to a close, holiday and Christmas markets as well as major New Year’s Eve events, presented cities with constant public event security needs. The public nature of these events increases risks of incidents with high-speed vehicles that put attendees in danger. Fortunately, there are three ways for public space managers to prevent casualty-causing collisions and further promote the use of local public areas. Developing an effective action plan When strategising how to react to an alert, think about what time of the year and time of day the event is occurring It is important to have a plan developed before an incident or accident occurs. Warning systems, utilising doppler radar and digital loop technologies, alert guards to abnormal vehicle velocity changes in the surrounding area. Managers of public areas should organise a meeting with public safety authorities and local agencies to discuss what must immediately occur when a high-speed vehicle is approaching a public event. When strategising how to react to an alert, think about what time of the year and time of day the event is occurring. Having such a reaction plan in place combines technology and strategic planning to ensure everyone is on the same page to effectively target a threat and promote overall event safety. Securing public areas Ideally, there will be no need to implement a well-conceived action plan. After all, taking preventive measures to secure public areas where events take place is important to keep people safe from accidental vehicle collisions and intentional attacks. Protect attendees by clearly separating pedestrian and vehicle locations using security devices such as – Barricades Portable barriers Bollards Install guard booths Avoid the risk of vandalism and theft, making sure people are safe when walking back to the cars at night by keeping parking areas illuminated with flood lights. Install guard booths with employees who monitor activity in the parking area and who are prepared to react if an alert is triggered. Furthermore, prevent accidental collisions by clearly marking the parking area with informative warning signs and using barricades to direct traffic. These three tips can be used by public area managers to promote security at the next community event. Additionally, the technologies used to secure an event can also be used as infrastructure for year-round security. Installing gates that shut when the public space is closed or using aesthetically pleasing bollards are steps any public area manager can take to promote community safety.
Atlanta’s new $1.5 billion stadium, home to the NFL Atlanta Falcons football team and MLS Atlanta United football club and site of the recent NCAA national college football championship, is protecting fans, personnel and athletes from terrorists and errant drivers from using vehicles as weapons. While the threat of terrorists planning to attack soft targets, such as stadiums increases, stadium security professionals, such as those at the new Mercedes-Benz Stadium, must look for the weak points throughout their facilities to determine where fanatics are most likely assailing. Taking their cue from hard target attacks, they and other stadium management understand that the use of vehicles, either to carry the people that will carry out the attack or act as the bomb itself, is a very real threat. New system, safer pedestrians Installed by Tusco, using Delta Scientific perimeter protection products, the new access system includes four DSC501 barriers, five DSC720 bollards, 39 DSC2000 barriers and 59 DSC680 fixed bollards. “We are very experienced with installing Delta equipment,” relates Brent Martina, President of Tusco. “Mercedes-Benz Stadium was very particular about their security needs and protocols and requested a customised sequence of operations for their security equipment. While the threat of terrorists planning to attack soft targets increases, stadium security professionals must look for the weak points throughout their facilities “Delta Scientific’s products and experienced engineers made them the obvious choice in meeting both the high quality and technical standards required to integrate with the stadium’s sophisticated security system. It was crucial to have a reliable team in place as we received a very compressed schedule to get everything complete by the first football game and, therefore, had no room for errors.” Because of long, straight approaches to some access points, stadiums oftentimes need to deploy high performance barriers. DSC501 barriers were used at main entrances where players and VIPs, among others, enter with their cars. Preventing attacks before they happen The DSC501 is the only K54-certified retractable vehicle barricade in the world. Set in a foundation only 18 inches deep, it will survive and operate after a 5.4-million-foot pound impact. That’s 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 areas. 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 very high velocities. The DSC720 is 35 inches tall and 15 inches wide. At Mercedes-Benz Stadium, the bollards feature brushed stainless-steel sleeves. Oftentimes, the ground below the access points are filled with cables, wires, pipes and other infrastructure products. As a result, typical, 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. This isn’t the only stadium using Delta equipment to protect staff and attendees from vehicle harm - Levi’s Stadium in San Francisco is a well-known user Delivery entrances are weaknesses 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 unauthorised vehicles from entering at all. At the loading docks, 39 of Delta’s fastest, smallest and shallowest 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 stainless steel sleeves protect pedestrian areas. They secure any unprotected locations where vehicle bombers and errant drivers have no obstacles. Versus cement barriers such as posts and pots, many organisations prefer fixed-post bollards for several reasons. Terrorists typically don't go where they see barricades, so placing them wherever possible attacks can happen reduces security risks dramatically That’s because, when hit, cement posts and pots can explode, literally spreading shrapnel throughout the crowd, potentially creating numerous injuries. 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 1-metre clearance regulations mandated by the Americans with Disabilities Act (ADA). The fixed bollard, which does not go up and down, provides a significant blocking device solution that continues to challenge security directors faced with threats such as stopping a vehicle from ploughing into the stadium’s inner perimeter. They let a facility manager 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 structures and other unprotected locales have to rely on unsightly ‘make-do’ solutions to stop car bombers or wayward drivers. One of the world's most secure “Delayed by roof issues, the Mercedes-Benz Stadium challenged us with a condensed schedule to provide one of the world’s most secure vehicle access systems,” avows Martina. “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’s Stadium in San Francisco (49ers) are well-known users. Unfortunately, most procurement offices won't allow vendors to 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), stopping 7.5-ton vehicles traveling 40 mph. Terrorists typically don't go where they see barricades, so placing 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 authorised people through.
With the changing “lone wolf” style of terrorism, there will be a trend toward many more installations of vehicle access control systems and smaller numbers of units. Where a university, military base or airport might have 20-plus systems scattered among its grounds, there will be a growing number of smaller applications needing one, two or three systems. These will include customers such as primary and secondary education facilities; pedestrian locations such as shopping centres, concert grounds and fairs; hospitals and other venues where pedestrians come together both daily or temporarily. Defending against vehicle attack The Middle East is a particular hotbed for increased security measures for explosive-laden vehicles. Many soft targets in the Middle East have also been adding anti-terrorist, crash-resistant barriers, barricades and bollards. This has been also true in Europe while Southeast Asia is coming on strong. With so many more such systems being ordered, buyers will need to become more aware of their supplier's customer service and technical support. The market could be faced with an upcoming slew of cut-throat, unscrupulous operators providing shoddy equipment and dangerous installations that take advantage of buyers who don't understand what is truly needed to defend against vehicle attack. Importance of certified vehicle barriers This time last year, we projected that the use of vehicles as weapons to mow down pedestrians, such as occurred in Nice (France), would probably impact greater sales of Delta portable crash-rated barricades. Although it was announced by ISIS that their followers should undertake more of these attacks, we don't think anyone anticipated the numbers of such atrocities we would see, the latest (as of this writing) the assault on the bike path in New York City. The largest customers around the world have been law enforcement agencies and municipalities. Security specialists needto be aware of vehicle threats wherever people are gathered Last year, we also warned that many organisations, in order to save money, were purchasing non-certified (non-rated) vehicles access control systems with less structural safety than those provided by certified manufacturers. The reality is that somebody is going to have to be hurt or killed before some buyers understand that a barrier, barricade or bollard is not a commodity type of product. Security specialists must be aware With the economy being better, there has been a resulting increase in sales of products for general parking and similar applications. But, as terrorist attacks have gone from large planned scenarios to smaller lone-wolf assaults, such as the bike path incident in New York, there is an increasing need for more protection from vehicle harm in more places. Basically, security specialists need to be aware of vehicle threats wherever people are gathered, from a parade route to a fair, sporting event, shopping centre – anywhere scores of people are clustered. One of the interesting statistics we ran across this year was that, in the United States, six of the top 10 rated college football teams use Delta temporary barricades to protect fans at their stadiums on game days. During 2017, Delta has been developing new products to take on the increased protection of vehicle checkpoints between the United States and Mexico. Over the years, Delta has implemented vehicle crossing protection at many of the most secure sites including El Paso, San Ysidro, Calexico, Otay Mesa and Tornhill-Guadalupe.
