Preliminary operations
Where installation is to be carried out in traffic, all necessary road signs must be set up in order to direct traffic and protect workers from vehicles, in accordance with safety regulations. The parts making up the road barrier can be unloaded from the transport vehicles by means of a crane fitted to the vehicle, or forklift truck, in accordance with current safety regulations. Workers must be supplied with all required equipment, including safety shoes, gloves and goggles and -where necessary - helmets, safety harnesses and all else specifically needed for the site and required by current safety regulations.

Installation sequence
The assembly diagram provides instructions for correct barrier installation. Fully and completely follow these instructions.
Main steps:
1.  Trace out a full line of reference on the ground, which will serve to align poles and beams.
2.  Place the beams along the traced line taking into account the direction of traffic.
3.  Posts (designated posts according to the drawings) are to be lifted vertically and planted in the
4.  ground1,080 mm (or designated) deep the holes in the top and spaced 2,000mm or 4,000mm apart. A pile-driver is generally used. During this phase, please check: alignment and level of posts, distance between posts, that they are vertical, and distance from the embankment, all in accordance with the measurements and tolerances specified in the applicable drawing of reference.
5.  Assemble the spacers to the uprights using the M16x50 mm bolts;
6.  Assemble the beams that have been laid on the ground, attaching them to the spacers with M16x45 bolts and the beam themselves by means of bolts M16x35 supplied.
7.  Use the calibrated pneumatic screwdrivers to fasten all nuts and bolts into place, checking levels and alignments.
8.  Installation must always take place under the surveillance of a specialist technician, and in full compliance with the final drawing and current safety regulations.

Inspection of installation conformity
The technician responsible for the installation shall, at the very least, control conformity of the following, prior to beginning assembly, during work and upon conclusion, by using all measurement instruments necessary and in his possession:
1.  Full compliance of the installation with the final drawings of reference.
2.  Pole spacing and height of upper beam and current edge in accordance with that specified on the final drawings of the barrier, dilation joints and ends.
