7.12 Installation Sequence
The following written instructions should be read in
conjunction with Ingal Civil Products’ drawings.
A generic Safe Work Method Statement is available from
Ingal Civil Products to assist in the safe installation of
Ezy-Guard 4. Suitable traffic control should be in place
before any works.
Only items purchased from Ingal Civil Products shall be
used for the construction of Ezy-Guard 4.
1. Ensure the area has been inspected for underground
hazards and where a service clash has been
identified, the barrier should be adjusted
longitudinally if possible.
2. Post locations are marked ensuring any fixed object
hazard is located outside the expected dynamic
deflection of the barrier.
3. The post lugs are to be at the top of the post and
facing the traffic as per Figure 13 and 14.
4. Posts are driven directly into the ground and should
be vertical. The post installation process shall not
cause damage to the post, such that it reduces the
effective operation of the safety barrier or its design
life, or introduces sharp tearing edges, nor shall it
cause damage to pavement. If the Ezy-Carriage
cannot freely move as it is attached to the post as a
result of deformation of the post during installation,
then the post shall be replaced.
The use of a vibrating post hammer will reduce
deformation to the top of the post and install the
post at a controlled rate.
5. Alternate to driving the posts, a minimum 110-
300mm hole can be augured and the post placed
in the hole. The posthole is then backfilled with the
material that was excavated. If installing in soil, the
material should be placed in layers of 150mm and
suitably compacted to not less than the density of
the surrounding layers.
6. Posts are spaced at 2m – Lesser spacings are required
on transitions to Thriebeam, and where requested
by an engineer.
7. The height of the Z-post above ground level is
777mm.
8. The Ezy-Carriage is attached to the face of the post.
The Ezy-Carriage will come to rest on the positioning
lug fabricated on the Z-post.
