HEAVY STEEL STRUCTURE & ERECTION
We engineer the backbone of modern infrastructure. Specialized in high-tolerance fabrication, complex heavy lifting, and advanced erection methods for national rail networks and industrial sectors.
Our Expertise
Core Capabilities
Precision engineering meets massive scale. We deliver high-performance solutions for the most demanding steel projects.
Railway Bridges
End-to-end fabrication and erection for Class 1 railroads. Certified for high-tolerance specifications and rapid deployment schedules.
Push Launching
Proprietary hydraulic incremental launching methods for bridges over environmentally sensitive areas or active highways.
Heavy Lifting
Complex rigging and lifting plans for structural components exceeding standard crane charts. Engineered safety first.
Technical Deep Dives
Complex Railway Bridge Fabrication
JWS GROUP specializes in the fabrication and erection of steel railway bridges. We understand the critical nature of minimal downtime and absolute precision required by rail operators.

Accelerated Bridge Construction (ABC) Techniques designed to replace spans within 24-48 hour windows.
Incremental Launching
When access below is impossible, we push forward. Our incremental launching capabilities allow us to build bridge superstructures in a stationary casting yard and push them out over the span.
