HISTORY: THE ROLE OF THE PERIMETER FENCE IN THE MODERN ERA

Posted by Michelle Goodwin on Thu, Jan 16, 2014

Chapter 3: The Role of the Perimeter Fence in the Modern Era.

In the last few hundred years, millions of refugees from have sought out the United States in pursuit of life, liberty & happiness. Tribes of oppressed people’s from all over the world have come to stake their claim on their very own piece of land; The American Dream. In more recent times, perimeter fencing has become prevalent for setting boundaries between much smaller structured civilizations rather than larger ones colonies of the past where neighbors were few and far between.

Increasingly compact urban populations and the invention of the sub-burbs not only allow for property owners to mark territory but they now encompass a homeowner's unique vision, and trends within popular culture and security specifications. 

Fence types, styles and materials vary thanks to the industrial revolution the fence options absolutely endless in the modern era. Aluminum, Wood, Privacy gates, security fence systems are just a few.

In the past century, there have been some highly notable and peculiar fencing structures that are well worth a fence google. Especially because the history of modern civilization and fence structures of all kinds go hand-in-hand.

Mehmet Ali Gökçeoğlu, a successful businessman and topographical engineer from Turkey, recently built the “world’s most fantastic” fence for his luxurious villa in Çeşme, Izmir. Eight years ago he replaced the wrought iron metal fence at the front of his property with a specialty 50-meter-long aquarium filled “fence” structure with hundreds of fish and octopuses. Above are the pictures to prove it.

Located just a few feet away from the shores of the Aegean Sea, Mehmet Ali Gökçeoğlu’s property has become one of the most popular tourist attractions in Çeşme, attracting up to a thousand visitors a day, according to its owner. The villa itself is pretty impressive, but it’s not what draws so many people to this place. They come to see the aqua-fence. Eight years ago, the Turkish businessman had the eccentric idea to replace the front fence of his home with a giant aquarium full of various marine creatures from the Aegean Sea. Building the transparent structure was actually the easy part of the project. The hard part was linking the aqua-fence to the Aegean through a 400-meter-long buried pipeline, so the water could be changed continuously to keep the aquarium looking clean and its inhabitants happy. Gökçeoğlu hired a team of private divers to perform the task, and ended up paying approximately 40,000 Turkish Lira ($21,000) to fulfill his dream. The businessman says just seeing people line up outside his house staring at his specialty fence creation makes it all worth it.

Stretching across two southeastern Australian states, Queensland and South Australia, the Dingo Fence is 5,614 kilometers long. 

Quick Facts about The World’s Longest Perimeter Fence:

5614 kilometers is the total length of the Dingo Fence.
8614 kilometers was the total length of the Dingo Fence up until 1980, where due to repair costs it was shortened to its present length.
26.5 million hectares of sheep and cattle grazing country is what the Dingo Fence protects.
5,614,000 meters of wire mesh, that stands 180 centimeters in height and is a further 30 centimeters underground, was used to build the Dingo Fence.
623,777 wooden and steel posts hold the Dingo Fence together.

The perimeter fence has a wide-range of cultural, psychological and historical tones. We put fences around everything. From the physical to the meta-physical. It’s in our nature. A fence evokes ownership pride of your surroundings It's the semblance just a small part of the planet we all share. Very few human characteristics can imply so much so without words. The fence concept is just another fascinating example of what it means to be a human being.

Where Is ATFP Fence Needed?

Posted by Kristen Fugere on Tue, Sep 18, 2012

Data Center Fence

AT/FP perimeter security systems are needed in any area that is in danger of attack from outside forces. Most commonly, we think of military bases, federal buildings and jails for this type of elevated security fencing. Other fence customers that are currently using this type of security are schools, banks, high tech data centers, and many other purposes. Typically any place that is housing large quantities of information, important people and money are high on the terror watch list. These fences are also commonly used by military and civilian airports and at nuclear power and industrial plants. In addition to these, federal institutions utilize this product for reserve banks, the Federal Bureau of Investigations and many other government fence needs. Very high levels of protection are essential in the mentioned target areas. ATFP fences are used for the protection of products, personnel and the general public. These types of institutions have been terrorist targets in the past, and because of this, AT-FP fence was developed.

ATFP stands for Anti-Terrorism/Force Protection, as defined by the US Army and other federal entities. The term refers to the amount of force a structure can withstand without being penetrated by an incoming vehicle. AT-FP ratings are achieved by reinforcing a fence structure with steel cables that run along the fence, into the ground, terminating into large concrete footers. Cable fence reinforcement consists of 2 cables stretching laterally at heights of both 30 and 35 inches. These specific heights are set at 30” to address cars and 35” for trucks. These cables are installed to meet Anti-Terrorism Force Protection fence standards. With these reinforcing ATFP cables and/or beams, a structure achieves certain ratings as detailed below. These ratings are typically referred to as “K” ratings, or crash ratings.  

A ‘K' rating is a Crash Test Certification issued by the Department of State (DOS) to a fence, gate, barrier or bollard indicating the perpendicular impact penetration of a vehicle of a specific weight at a specific speed. In other words, it measures the particular stopping power of a barrier in relation to the speed and weight of an incoming vehicle.  The K-rating weight of the vehicle is standard at 15,000 lbs. These DOS standard barriers allow the truck to penetrate no more than 36 inches past the bed. There are three ratings that are achievable; K4, K8, and K12.

  • A K-4 system, which is two 3/4" cabling with concrete anchoring deadman will stop a 15,000 pound vehicle traveling at 30 miles per hour.
  • A K-8 system with two 3/4" cabling and 1" cable with concrete deadman will halt a 15,000 pound vehicle at a maximum speed of 40 miles per hour.
  • A K-12 system with three 1" cables will prevent penetration of a 15,000 pound vehicle with a maximum acceleration 50 miles per hour.

K-rated crash test

These k-ratings can be achieved by any combination of natural and manmade features when natural barriers are not sufficient or present. Distance alone can be a great ATFP device when used in combination with an uneven or bumpy surface. This can also be achieved with ditches and berms, or large bolder (3ft. x 5ft.) placement and forestation. This will slow down any moving vehicle or a truck bomb that is attempting to implode a building surface. Remember that AT/FP perimeters are specifically intended to stop only vehicle traffic. This perimeter prevents a bomb threat, not theft.

These ratings are also being covered by American Society for Testing and Materials or ASTM. ASTM International is a globally recognized leader in the development and delivery of international voluntary consensus standards. Today, some 12,000 ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. ATSM fence is also available by qualified fence professionals.

What Type Of Fence Styles Can Be ATFP Compliant?

Posted by Kristen Fugere on Wed, Sep 05, 2012

Essentially, any type of fence can be modified to meet AT/FP requirements.

Data Center Security FenceATFP stands for Anti-Terrorism/Force Protection, as defined by the US Army and other federal entities. This term refers to the amount of force a structure can withstand without being compromised by an incoming attack.

The AT-FP ratings are achieved by reinforcing a fence structure with steel cables that run along the fence, into the ground, terminating in concrete footers. These ratings are typically referred to as crash ratings, or “K” ratings. There are three K ratings that are achievable; K4, K8, and K12. The different ratings refer to the amount of weight the structure can resist and remain intact. 

Typically, if business or government institution is going to spend this amount of money on a high tech fence, they may also want a good-looking fence. The most aesthetically pleasing type of fence that can be modified to achieve ATFP ratings is ornamental fence. Ornamental fence is often referred to as “wrought iron”, but are in fact made of aluminum or steel. Iron is an outdated material. These contemporary fence alternatives are more economical, as well as outlasting their dated counterparts. These style fences are often found around the perimeter of military institutions, data centers, federal buildings or even schools.

Alternatively, jails and other institutions that must remain secure without the superficial attributes can also apply K rated cables to chain link fences, achieving the same degree of security. These ATFP compliant chainlink fences are usually constructed of 6 gauge wire as opposed to the more commercially applied 9 gauge wire. This thicker wire, coupled with cable reinforcement and either SS 40 or SCH 40 pipe, can achieve AT/FP federal security standards.

Data Center FenceWhile ornamental styles are the most common installations of crash rated fences, even a wooden fence could be modified to reach the same standard. One way to achieve AT/FP compliance in this type of fence installation is to install a line of bollards, again reinforced with steel cables, in front of a wood fence. This would allow it to attain a K-rated fence standard. Bollards are short, vertical posts used to protect potentially vulnerable structures or objects from damage by moving vehicles. Designed for versatility, these posts range in size from 24” to 42” in height, and come in variable diameters to meet a location’s specific security requirements. Bollards can be used to maintain a more natural look, while providing crash-rated security.

As you can see, Anti-terrorism Force Protection (ATFP) standards can be met in any number of ways in the fence industry. A knowledgeable fence contractor has the capability to help customers design and build crash-rated fences out any material the customer desires. As our society continues to evolve, so do potential acts of terror, and Top Notch Fence Company’s will stay on the cutting edge of technology to continue to provide our customers with ATFP compliant crash rated fences.

Amtrak Fencing Needed For Public Safety?

Posted by Dawn Lowndes on Tue, May 31, 2011

Define safety

  1. the state of being safe; freedom from the occurrence or risk.amtrak fence
  2. the quality of averting or not causing injury, danger, or loss.
  3. a contrivance or device to prevent injury or avert danger.  

A specific case highlighting numerous Amtrak related deaths in Middle river Maryland, which is northeast of Baltimore City shows the grave need for safety fence near populated areas with exposed rails. All of the Middle River Amtrak deaths are tragic and include the death of Anna Marie Stickel. Anna was a 14 year old girl who was killed on the tracks in January of 2010. This particular death and other closely related incidents initiated a dramatic public response that promted Amtrak to respond in the following postive way.  

A lot of sources have chimed in on the  Amtrak Safety topic :
 
AN article published by The Amtrak Police Department titled; Amtrak installing new heavy steel fence along High-speed tracks in Middle River, Maryland informs the public that,
Amtrak is installing a heavy steel, 8-foot high, high security fence along a portion of its high-speed tracks in Middle River, Maryland to deter access to the railroad. The Middle River community is located about 11 miles north of Baltimore and is within the busy Northeast Corridor home to frequent and daily Amtrak train service.  The section of track where the fence is being installed includes Acela Express and Northeast Regional service that operate at speeds up to 125 mph as well as some freight train traffic.  
Beginning in late-April, work will commence work on the installation of new fencing on both sides of the tracks from Martin Boulevard southwest to where it meets up with an existing fence. (See Fence Contractors) A portion of the existing fence also will be replaced.  In all, more than 6,400-feet of fencing will be installed and additional “No Trespassing” signs will be posted.     


Baltimore Sun reported the following in April of 2011  
But now Amtrak is planning to do something about the problem. It's going beyond what this column urged and is spending $3.1 million to rip out the chain-link fence entirely and replace it with a barrier it believes will deter even the most determined would-be trespasser. The new 8-foot-high fence will run from Martin Boulevard to Stemmers Run Road, a section that includes the spot where Anna died. Amtrak spokeswoman Danelle Hunter said the railroad is investing in an Impasse Anti-Scale Fence System, so named because it is designed to be difficult to get over. Hunter said it will be sunk into the ground so intruders can't get under it and will be made of sturdier material than chain link so an intruder can't get through it with bolt cutters.  


Hurricane Fence professional Todd Jones says
“He has come to understand that intruders on the track are a great concern to the train operators. Having the potential stress of hitting pedestrians or vehicles causes them undue work related fatigue.”  


The $3.1 million fencing project will take approximately six months to complete. When completed, there will be nearly two miles of continuous fencing from Martin Boulevard to Stemmers Run Road. Individuals may use the pedestrian underpass at Martin Boulevard, which will also be improved as part of the project, to safely cross to the other side of the tracks.   

 

“The new fence will make it harder for a person to access the tracks, but to achieve maximum safety individuals must make the right decision to stay off the tracks and not use it as a shortcut,” says Amtrak Chief of Police John O’Connor.  


“Our most important goal is safety,” said Congressman Dutch Ruppersberger. “I am pleased Amtrak is taking these significant steps, building taller and stronger fencing. I thank everyone who had a role in this project, working together to make Middle River a safer community for everyone.”    

Amtrak asks public to join efforts to improve safety and security of America’s Railroad

PASS program helps protect passengers, trains and stations

To help protect Amtrak passengers, trains and stations, America’s Railroad is starting a new neighborhood watch style program that encourages passengers and the public to be on alert and report safety or security issues.

The goal of the Partners for Amtrak Safety and Security (PASS) program is to utilize the knowledge of passengers and community members who travel throughout the Amtrak national system in identifying behaviors or activities that are unusual or out of the ordinary at stations or on board trains. Items that should be reported to Amtrak Police include trespassers, vehicles near the railroad, suspicious packages and vandalism.
“The PASS program enhances our efforts to further engage the public and passengers to say something when they see something that they sense is just not right,” said Amtrak Police Chief John O’Connor.

Amtrak also participates in Operation Lifesaver, a national, non-profit organization that promotes education, enforcement and engineering solutions to prevent trespasser incidents.  Amtrak’s work in Middle River includes the installation of the new fence, community outreach by the Amtrak Police Department to the local high school and local law enforcement, and active police patrols of the area by Amtrak and Baltimore County Police.

After the Department of Homeland Security's intelligence warning sent to law enforcement around the country suggesting trains and train tracks could be a target, I checked with Amtrak Friday morning to see if there were any changes in security at St. Louis area Amtrak stations.


Here is Amtrak's response to my question:
"Amtrak received the DHS advisory.  Furthermore, there are several members of the Amtrak Police Department assigned to the Joint Terrorism Task Forces around the country. As such, we are immediately privy to any intelligence with respect to threats against rail.  Amtrak employees remain at a heightened state of vigilance and we will employ appropriate countermeasures as and when necessary."
The spokesperson said they would have no further comment.

Who Requires Cable Reinforcement On Security Fences And Gates?

Posted by Dawn Lowndes on Thu, Feb 03, 2011
Cable fence reinforcement consists of 2 cables stretching laterally at heights of both 30 and 35 inches. The specific heights are set at 30” to address cars and 35” for trucks. These cables can be installed to meet the Anti-Terrorism Force Protection (ATFP) standards as detailed below. They are typically placed in conjunction with chainlink fence as an additional measure to stop a vehicle from penetrating any perimeter.

Cable reinforcement is commonly used by military bases, military and civilian airports and at nuclear power and industrial plants.  In addition to these federal institutions utilize this product for reserve banks, the Federal Bureau of Investigations and many other government offices.

Higher levels of protection are essential in the previously mentioned target areas for the protection of products, personnel and the general public.

Some specific examples of areas protected by cable reinforced fences or gates are:

Military – housing, equipment facilities and personnel offices.

        Airports - foot traffic, planes, fuel trucks and access roads.

        Industrial plants - toxic and explosive materials as well as vital power grids.

        Financial businesses with large structures and mass amounts of employees.

Over the last two decades, the Department of State established an Anti-Terrorism Force Protection (ATFP) rating system to help prevent vehicles from entering a facility’s perimeter and creating a bomb threat.  When deciding on an Anti-Terrorism Force Protection (ATFP) cable system one needs to review the following criteria for need:

Is this facility a potential target for terrorist to attack?

Where would this potential assault originate? 

Are there roads leading into the property in question?

Are there parking lots in which a car could achieve a speed with which perimeter penetration could occur?

k12 fence virginia

When deciding what your threat area may be, you will need to determine the level of protection desired by determining what level of security is required at the facility.  For example a nuclear power plant would more than likely require a K-12 higher rated security fence.

There are K ratings for cable reinforcements that assist in determining impact and speed volumes. They are as follows:

  • A K-4 system, which is two 3/4" cabling with concrete anchoring deadman will stop a 15,000 pound vehicle traveling at 30 miles per hour.
  • A K-8 system with two 3/4" cabling and 1" cable with concrete deadman will halt a 15,000 pound vehicle at a maximum speed of 40 miles per hour.
  • A K-12 systemwith three 1" cables will prevent penetration of a 15,000 pound vehicle with a maximum acceleration 50 miles per hour.

When determining your needs and selecting a system make certain to knowledgeably assess your desired level of protection. The rate specificity can affect installation costs. When choosing your fence company it’s always a good idea to get at least three references on similar type projects.  If you no clarity on what to look at to determine your need a qualified fence professional will be able to help you in this process. Hurricane Fence Company has been installing reinforcement cable systems for over fifteen years and keeps current on any changes federal standards.
