Delivery & Offloading
It is the contractors responsibility to offload the box culverts on delivery.
A hard level access area should be provided which can be used safely by standard articulated delivery vehicles.
The contractor should provide a suitable crane of adequate capacity for lifting the culvert.
For reasons of safety and economy certain box culverts are delivered to site on end rather than as laid, and will require a safe method of turning during offloading.
A data sheet giving guidance of lifting and turning is available and is issued to clients prior to the first delivery. The offloaded box culverts should be placed carefully on a firm level base away from the edge of the trench, and if any further movement is required it should be by lifting; the culvert should never be dragged or dropped.
