Joe Wagner Group was contracted to provide the civil drainage works for an upgrade of the Jilalan Wagon Overhaul Facility at Sarina.

Works included:

• Laying of subgrade and geofabric
• Installation of precast concrete pipes and culverts (600mm t0 1200mm)
• Installation of precast headwalls and pits
• Construction of concrete aprons for culvert outlets including rat walls
• Backfill with aggregate to top of pipes for the client to complete

The pipes were laid along a 250-metre course in a 4-barrel configuration. As per the client’s plans, the pipes were laid on a curve which required extreme accuracy.

Despite very wet weather, our crew completed the job on time with no LTIs.
