About The Project
The Pym Street pedestrian bridge needed to be fully assembled and ready for installation before it reached site. At 100 tonnes and 64 metres long, the project required precise fabrication, architectural finishing, and compliance testing to be completed off-site ahead of transport. Bowhill Engineering has successfully fabricated and delivered the steel bridge structure for McConnell Dowell.
Our Solution
Bowhill has proven that it is feasible to deliver structures of this scale in a highly value-added state prior to delivery to the site. For this project, the bridge structure included a walkway, handrail, safety mesh (walls and ceiling), architectural features (S/S strips woven into safety mesh), and electrical conduits. Fully tested, surveyed, compliant, and ready for installation.
The delivery method significantly reduced traffic interruption and removed the need for onsite assembly space. It also reduced program slippage, as risks like assembly clashes, missing components, inclement weather, defects rectification, and compliance documentation were almost entirely eliminated.
Safety increased as we had nearly all work done at ground level, in a building on a manufacturing site rather than on public property. This is carried out by qualified staff using familiar equipment, during the day, in a controlled environment away from traffic and public.
About Bowhill Engineering
Bowhill Engineering has built a reputation for delivering large-scale steel structures fully assembled and ready to install, cutting down the work required once a project reaches site.
Behind every solution is a team of qualified boilermakers, metal fabricators, welders, and CNC operators, working alongside project managers and robotic welder operators on the floor of our Murraylands manufacturing facility.
- Off-site assembly capability – Structures fabricated, fitted out, and tested in our own facility before transport to site
- Precision manufacturing – Robotic welding and CNC machining equipment built for complex, high-tolerance structural work
- Heavy structural capacity – Components from 5 tonnes to 140 tonnes, supported by overhead cranes up to 100 tonnes
- Certified to national standards – AS5131 CC3 structural steel fabrication, ISO9001, AS4801, ISO14001, and Weld Australia AS3834.2
- Track record on major projects – Including Torrens to Darlington at 6,600 tonnes, Inland Rail bridges, and public transport infrastructure
- National delivery from a regional base – Based in South Australia, supplying projects in Victoria, NSW, NT, and beyond
- Design input from day one – Working with contractors early to optimise fabrication, transport, and installation outcomes
- Safety built into every stage – A strong safety culture and environmental compliance carried through from fabrication to site
Together we thrive. We invest in our people, our technology and our regional community to deliver structural steel solutions that matter.
