Barrier supply goes wrong when it is treated as a simple delivery. The units have to match the approved drawing, be approved before production, be lifted safely beside moving traffic, and often be moved again as traffic phases change. Planning those steps early keeps the barriers off your critical path.
What the barriers are for
New Jersey barriers are precast reinforced-concrete units with a sloped profile. On road and infrastructure projects they separate traffic from work zones, close lanes, divide carriageways and protect site perimeters, temporarily or permanently.
Fix the specification before you order
- The barrier profile or drawing the project approves, and the quantity.
- The material and performance requirements in the project specification.
- Project markings, codes and any reflective delineators to be applied.
- How units connect to each other along the line.
- Lifting provisions in the unit, such as cast-in anchors, so the lifting plan can be written around them.
Allow time for approval
On road programmes the supplier is usually approved before production starts. Expect to submit drawings, material information, management-system certificates and records of previous work. Have these ready in one pack, because an incomplete pack invites comments and resubmission rounds.
Production and delivery
- Agree the delivery programme in phases that match where you will place the units, rather than one bulk delivery to a congested site.
- Reinforced units should be inspected at each production stage, with markings and reflective finish applied before dispatch.
- Confirm the laydown area on site so units are protected from damage and site traffic before placement.
Lifting and placement beside traffic
- Every lift runs under a lifting plan with certified equipment, and a banksman controls the area.
- Check ground bearing before a crane or telehandler sets up, and keep an exclusion zone around the lift.
- Work behind a protected zone, in high-visibility PPE, under a traffic management plan approved for the lane closures.
- Keep hands clear of barrier joints during set-down, using tag lines and push-pull tools.
Relocation and removal
If traffic phases change, the barriers move with them. Decide at the start who relocates the units, how many moves are expected, and who removes them at the end, so the cost is in the quote and not a variation later.
Barriers with hoarding on top
On road frontages, hoarding panels can be fixed to the barriers where the design allows. Taking the barrier and the hoarding from one supplier means one drawing set, one programme and one team on the road. Bariq Arabia manufactures precast barriers and fabricates and prints hoarding in-house, and has supplied the two together on a Riyadh road project.
