Concrete Jersey barriers are designed to do one job very well: separate people, traffic and work zones, but on live construction sites, they often end up being asked to do much more.
One client needed signage mounted to the barriers, but there was a practical problem. The signs could not sit directly above the barrier because passing truck mirrors needed clearance.
The traditional options were not particularly elegant. The signs could be concreted into the ground, or mounted into separate precast blocks. Either approach meant introducing more material, more handling and another element into an already busy work zone.
NON-DRILL approached the problem differently. The Jersey barriers already contained lifting anchors. Rather than build another footing beside the barrier, the team developed an offset connection that used those existing anchors and positioned the sign away from the traffic path.
The job became a connection problem rather than a concrete problem. That distinction matters.
Existing infrastructure can often do more than one job
Lifting anchors are generally thought about during manufacture, transport and placement. Once the barrier is installed, their original task is effectively finished, but that does not necessarily mean the connection has no further value.
Where the engineering allows it, an existing structural connection may become part of a temporary-works solution without requiring another hole, footing or block of concrete.
The design also had to work across different Jersey barrier arrangements, including barriers with staggered anchor locations. Instead of producing a one-off answer for one barrier, NON-DRILL developed the connection to accommodate different layouts.
That is the broader lesson from the project.
Good temporary works should adapt to the structure rather than force the structure to adapt to them.
For project teams, the question is worth asking early: Before we excavate, drill or pour another footing, is there already a suitable engineered connection available?
Sometimes there isn't, but when there is, using it intelligently can make the whole site methodology simpler.
