Automated Allowable-Loading Calculator for Nuclear Underground Structures, Integrated with Navisworks

The Challenge

On a new nuclear power plant programme, engineers had to determine the allowable loading on a large population of underground structures — a calculation-heavy, safety-critical task repeated across many structures and constantly disturbed by design changes flowing through the federated BIM model. Keeping manual checks synchronised with the model was slow and error-prone.

The Solution

We built a tool that automatically calculates the allowable loading of underground nuclear structures from the governing design inputs and integrates directly with Autodesk Navisworks — reading structure data from the coordinated BIM model and surfacing allowable-load status against the live design. Loading assessments stayed in step with model changes, giving the programme rapid, auditable visibility across every structure.
