Structural Steelwork
Our structural steelwork solutions combine advanced CAD design with precision fabrication to deliver durable, code-compliant metallic structures. Specialising in complex geometries for bridges, viaducts, and industrial facilities, we ensure dimensional accuracy through 3D laser scanning. With CE marking to BSEN 1090-2:2008, our processes guarantee weld quality and material traceability for critical infrastructure projects.
Design Engineering
End-to-end design services utilise BIM Level 2 workflows to resolve buildability challenges digitally before fabrication. Our in-house team creates detailed 3D models that coordinate with existing infrastructure, minimising site adjustments. This approach reduces project risk through clash detection and virtual construction sequencing, ensuring first-time fit for complex steel assemblies in rail and marine environments.
Installation
Professional installation services execute precision steelwork across challenging environments, including live rail corridors and marine settings. Our certified teams implement strict safety protocols while maintaining dimensional tolerances within 3mm. Temporary works design and lifting calculations ensure safe erection of components weighing up to 50 tonnes, supported by real-time quality assurance documentation.
Structural Repairs
Reactive structural repair services address urgent infrastructure failures with rapid mobilisation of specialist teams. We provide temporary propping systems and permanent reinstatement solutions for damaged steel elements. Our engineers conduct condition assessments using ultrasonic thickness testing, delivering repair strategies that restore structural integrity while minimising operational disruption for rail and highway clients.
BIM Modelling
BIM Level 2 compliant digital engineering services enhance project coordination through federated 3D models. We create detailed fabrication drawings and construction sequences that integrate with client asset management systems. Our models support quantity take-offs, construction planning, and facilities management, reducing errors through enhanced visualisation and data-rich component specifications.
