Shallow foundation bollard arrays

Palmdale, California (USA)

Delta Scientific announce its new DSC650 Shallow Foundation Bollard arrays, a down-scaled version of the DSC600 arrays announced in August of 2007. The new DSC650 fixed bollard modules will stop a 5000-pound (2300 kg) vehicle going 50 mph (80 kph) while the DSC600 array stops a 15,000-pound (6900 kg) vehicle going the same speed.

The DSC650 module functions as a standalone module or part of an extended array on shallow substrates, including those that are not level or have turns. Two modules are available. The first model provides a choice of having either one or two of the bollards being removable, to let vehicles through, and lockable so they cannot be removed by unauthorized people. The second is a corner module of 90 degrees featuring three bollards. Both versions need only a 12-inch (30.4 cm) foundation and both are available with Delta standard or custom decorative cast aluminum or fiberglass coverings.

"With our DSC600 modules, we have found a great demand for low complexity, low cost installation fixed bollards that can be easily installed on shallow foundation locations featuring curves and inclines," attests David Dickinson, Delta Scientific senior vice president. "However, many customers have told us that they don't need as hardy a bollard as the DSC600. Stopping the same vehicle at one-third the speed would be more than adequate. As a result, we can now offer them the DSC650 at a lower price."

With a foundation only 12 inches (30.4 cm) deep versus the four foot (1.2 m) core typically required by crash tested retractable bollards, Delta's new DSC650 Shallow Foundation Bollards can be installed within sidewalks, on top of concrete deck truss bridges or in planters as well as conform to the inclines and turns of a locale. To make installation even easier, the DSC650 is supplied with steel reinforcing mesh welded in place so that no additional rebar is needed.

The new DSC650 bollard modules were tested in accordance with ASTM Designation F 2656-07 Standard Test Method for Vehicle Crash Testing of Perimeter Barriers - August 1, 2007 with a rating of PU50/P1 with a 5,070 pound (2300 kg) truck traveling 50 mph (80 kph). The certified dynamic and final penetrations were less than 1 meter. As a result, the DSC650 successfully meets the U.S. Department of State Specification, Revision A that requires the bed of the attacking truck to go less than 39 inches (1 m) beyond the point of impact.

Like its predecessor DSC600 modules, the new DSC650 Shallow Foundation Bollards will protect approaches to buildings, drop-off and passenger loading areas at transportation hubs, storefronts, sports arenas, office buildings and other presently unprotected locations where vehicle bombers and errant drivers have no obstacles to stop them. Those facilities surrounded by streets, abutting sidewalks and set back on lawns, such as many state capitals, other government structures, stadiums, theaters, and commercial buildings, can now be effectively protected.

The DSC650 Shallow Foundation Bollards are also perfect for high water table locations and areas with corrosive soils. The shallow foundation obviates the concerns of interference with buried water, gas and fuel pipes, storm drains, power lines and fiber optic communication lines. This foundation also reduces installation complexity, time, materials and corresponding costs.
