NEW BRIDGE OVER HUMBUG CREEK

Client: John Holland Rail

Project: Humbug Creek Bridge, Ungarie NSW

Barnson’s Role: Environmental planning, civil and structural engineering design and drafting, tendering, surveying, and geotechnical work

Time frame: 12-month project, completed late 2013

Late in 2013, Barnson completed a year-long project for John Holland Rail to upgrade a bridge over Humbug Creek at Ungarie, near Lake Cargelligo. The goal was to replace the timber and concrete bridge with new, precast panels.

The project involved Barnson’s civil and structural engineering, surveying, and geotechnical teams. The design, procuring the culverts, environmental planning, and tendering the installation were also part of Barnson’s role on this job.

The geotechnical team also completed the drilling and compaction necessary for the project. The staff were challenged by working in a creek bed in all weather conditions.  

Addressing the environmental requirements of the project posed a challenge. The creek is now home to increased birdlife, reportedly including several Fairy Martin nests. The outcome has been a larger flow capacity for Humbug Creek.
