Event | CS454 Assessment Project Application

✏️Session Overview

This technical webinar presents a practical application of CS454 bridge assessment through real project examples delivered by Abinash Acharya, Technical Lead Bridge Engineer at WSP.

The session shows how CS454 and associated DMRB standards are applied to two UK bridge assessment projects and how these are efficiently implemented using MIDAS Civil.

WSP will present:

✔️A multi-span post-tensioned concrete bridge assessed in accordance with CS 454 and CS 455
✔️A steel–concrete composite bridge assessed in accordance with CS 454, CS 455, CS 456 and CS 457

Key challenges including geometric complexity, modelling strategy, and assessment-driven decision-making will be discussed.

Following this, Dev, Technical Support Engineer at MIDAS IT, will demonstrate a CS454-compliant moving load analysis and automated Excel report generation in MIDAS Civil NX, showing a complete, practical assessment workflow from model to report.

👀 This Session Helps You If You’re

✔️ Responsible for CS454 assessment of highway bridges
✔️ A bridge or structural engineer involved in assessment, strengthening, or re-rating projects
✔️ Working with or planning to use MIDAS Civil NX for bridge assessment and reporting
✔️ Dealing with multi-span, post-tensioned, or steel composite bridges
✔️ Managing models with geometric complexity and construction sequence effects
✔️ Looking to streamline both analysis and report generation in accordance with CS454
