Installation Details
It is important that before any installation is carried out the correct planning and preparation
takes place which includes a site visit. This is necessary to keep to a minimum the time spent
on site and that the installation goes quickly and without issue. Things that need to be
considered and checked are, any lifting restrictions i.e. low bridges, any underground services
in the vicinity of drilling operations, layout and alignment of the barrier including any radii that
the barrier may have to go round. It is important to also ensure the correct loading of the
BarrierGuard 800, i.e. it is put on to the delivery truck the right way around and the terminal
sections are in the correct place on the load.
The ground conditions that the barrier is to be installed on and anchored to need to be
established to ensure the correct anchoring choice is made and the appropriate anchor shoe is
connected to the barrier. Full details of common ground conditions and the available types of
anchors and anchor shoes can be found on pages 10 to 12. For use of BarrierGuard 800 on
any ground conditions or anchors that are not shown in this drawing please contact CSP
Pacific for advice.
Standard NCHRP 350 tested BarrierGuard 800 only requires anchoring to the ground at each
end of a run, there are integral anchor points beneath an easily removed cover at the extreme
end of the specially designed anchor sections. There is a second anchor point at the first
bolted joint up stream of the end of the section; these anchors can either be external or
internal anchor shoes depending upon site restrictions or preference. Both the anchor shoes
and the integral anchor points require 4 x anchor pins/bolts each (8 in total per end anchor
section).
The Length of Need of BarrierGuard 800 is the total installed length between the two Inner
Anchor Shoes.
The Beginning of the Length of Need is measured 6m from the approach (upstream) end of
the BarrierGuard 800 terminal (at the Inner Anchor Shoe). If an approved, gating (non-
redirective) end termination such as an ABSORB 350® crash cushion is connected to the
BarrierGuard 800 terminal, then the Beginning of the Length of Need is 6m from the approach
(upstream) end of the BarrierGuard 800 terminal (Inner Anchor point). If an approved, non-
gating (redirective) end termination such as a TAU II® crash cushion is connected to the
BarrierGuard 800 terminal, then the approach (upstream) end of such system becomes the
beginning of the Length of Need.
When deciding Length of Need of a system consideration must be given to the proximity of any
anchor points to any excavations, if the BarrierGuard 800 is to be used to protect errant
vehicles from excavations we recommend that the anchoring takes place beyond any
excavation and if any extra anchoring is required it should be single sided away from the
excavated face.
The minimum recommended installed length of BarrierGuard 800 is 18m between Inner
Anchor Shoes i.e. for an installation with no approved crash cushion connected to the end
terminal; the minimum total system length including terminals and anchors is 60m. Please
refer to the relevant drawings located in Appendix A.
