Attack Prevention
into pre-drilled holes in the anchor posts. No extra expenses, no ex- tra labor to build elaborate cages. In addition, post and beam fences are engineered to be extremely simple and efficient in terms of the hardware used and the effort required for construction.
The time-saving design, ultimately, leads to abundant savings. Digging 75 percent less post holes speaks for itself, but a post and beam fence directly saves time, and labor costs, in several other ways: • Little or no time spent building rebar cages
• Post hole foundations are shallower than cable-based anchor posts, and require less concrete
• Installing a single beam, connected by one nut and one bolt on each post, versus multiple runs of cable
This simplicity in installation, coupled with high crash test stan-
dards, led a post and beam fence to being specified to protect a Saudi Aramco facility, the world’s largest oil and gas company, and a gov- ernment property owned by Saudi Arabia. The Saudi Aramco crew installed the post and beam fence at a rate of 1,000 meters per week with a relatively small crew—this is a process that is two to three times faster than installing a cable-based fence system.
“Installation of a post and beam fence saved us a tremendous amount of time, at least 50 percent versus other fence systems,” says Peter Saroufim at BRC Industrial (Saudi) LTD, in Jeddah, Saudi Arabia. “There is less excavation and less concrete to use. The whole process is much simpler, and you’re left with a product that does an exceptional job of protecting a perimeter and will not need any
maintenance once it’s installed.”
When it comes time to choose an anti-ram fence for preventing
vehicle ramming attacks, considering all of these factors will deter- mine the type of fence that is ultimately chosen. Focusing on require- ments (required crash test ratings), financials (differing installation costs) and preferences (aesthetics of post and beam vs. cable-based) is a great basis to selecting the proper anti-ram fence.
