3.2. Pre-Installation Considerations
Before beginning site excavation and barrier installation, note the following important
considerations.

Inspect the site and verify there are no underground utilities or overhead wires or
obstructions in the excavation area.

If possible, locate the installation away from routine foot traffic to reduce the chance
for pedestrian injury from the barrier's moving arm.

Soil compression strength around the barrier shall be a minimum of 1600 PSF (76.6
kN/m
2
) or per submittal guidelines. Compact and add gravel where necessary to
ensure solid soil base. Consult B&B Technical Support if soil compressive strength
does not meet this minimum requirement.

The barrier operates best when installed on a level surface. Both drive and receiver
stanchions should be plumb and level. Level site side-to-side prior to barrier
installation.

Excavate install site to accommodate a minimum concrete pad dimension shown to
match size of the barrier you have purchased. If site excavation cannot be completed
per these minimum dimensions, please contact B&B Technical Support.
