High Risk Projects & Consultation – Daracon, Singleton Bridge Replacement
Daracon needed to lower a worker 7m into the vertical casing that would later be filled with concrete to form the pilons. The person entering the confined space would have to join the vertical torsion bars and align them for the engineers. This presented a number of challenges as it involved both height safety and confined space entries for the 20m deep casings for the reinforcement bars for the new bridge footings. A specialist was needed to manage the potential hazards and set up safe entry for the worker.
This job also had serious time constraints due to the rail shut down which allowed a small window to complete the replacement.
Zokal’s Confined Space and Height Safety Solution
Zokal attended onsite meetings with all stakeholders prior to the job to scope the task, potential hazards, controls, rescue plan required equipment and procedures.
We then set up a a tripod and rope positioning device to lower the worker into position. We also set up confined space safety protocol including a standby and rescue plan as there was potential for gases, vapour and low o2 in the casing.
Adjacent to the vertical casing was the rail corridor and mobile equipment being used for the replacement, drill rig, cranes, cement truck, etc.
