How BIM Benefits Structural Engineers

The world of structural engineering is experiencing a seismic shift thanks to the adoption of building information modeling (BIM). This technology has transformed the way structural engineers design, analyze, and construct buildings. The days of 2D drawings and hand calculations are fading fast, and the future is looking brighter than ever with the continued advancement of BIM workflows.

So, grab your coffee, and let's dive into how BIM is benefiting structural engineers!

Improving Productivity

BIM can save time for structural engineers by reducing coordination efforts and allowing them to focus on problem-solving.

Engineers can use BIM to isolate, filter, and visualize specific areas of the building structure, leading to more innovative solutions.

BIM can also reduce design errors and boost productivity, resulting in lower costs.

Better real-time coordination

The use of a single building information model during both the analysis and documentation phases enhances coordination and promotes consistency in structural design.

With its collaborative nature and data-driven approach, the BIM process enables structural engineers to make better design decisions while improving project team coordination.

By addressing coordination issues in the design phase rather than waiting until construction, the BIM process increases accuracy and reduces errors.

Involving more stakeholders in a construction project can lead to extra coordination work and increased potential for mistakes and rework. Fortunately, structural engineers can use BIM to streamline coordination and simplify their work.

How BIM Benefits Structural Engineers

Visualization and Simulation

BIM enables structural engineers to design, analyze, simulate, and document projects more efficiently.

Visualizing projects using different methods enhances the predictability and behavior of structures. The 3D model produced by BIM facilitates the examination of structural stability and performance.

Renderings and animations derived from the BIM model can help simplify the explanation of complex scenarios. These visuals allow teams to communicate more effectively and convey ideas more clearly.

Phasing

Structural engineers can use phasing as a part of the analytical process in their projects, enabling them to calculate each stage of construction accurately.

BIM's 4D phasing combined with management is another practical application of BIM in a project. It also supports multidisciplinary coordination (3D), conflict detection, coordination, and compatibility between all areas and structures.

With BIM, conflicts, such as those between the architect and engineer, can be automatically detected and quickly resolved. It also helps to verify product compatibility, saving time and resources.

Bringing Design and Details Together

BIM provides a big-picture view that helps to detect design flaws and inspire fresh solutions.

Autodesk Revit, ArchiCAD, Vector works, and other BIM authoring tools allow structural engineers to create realistic building structures.

Collaboration and documentation are simplified with 3D modeling software used by structural engineers and designers.

The constant updating of the model with changes in design and standards, as well as the accurate maintenance of data, are key benefits of BIM for structural engineers.

Superior Project Insights

BIM provides structural engineers with access to all the necessary data about built-in models. With all components of the project unified in one model, advanced BIM software can adjust to the supplied data, enabling engineers to identify problems during the design stage.

Structural engineers can swiftly extract and filter any section or component of the structure of particular interest and visualize it in 3D. This enhances the project's comprehension, provides superior project insight, and makes problem-solving and idea generation easier.

BIM enables structural engineers to understand how their model will perform in a practical setting.

Conclusion

In conclusion, BIM has revolutionized the way structural engineers work, allowing them to collaborate better and more efficiently on construction projects. The use of BIM has helped structural engineers to visualize, design, simulate, and document their projects more effectively, leading to increased productivity and cost savings.

By providing a single source of truth for all stakeholders, BIM has allowed for greater coordination and communication between team members, reducing the risk of errors and conflicts.

As BIM technology continues to evolve, structural engineers will undoubtedly continue to benefit from its data-driven, collaborative approach to construction.

Frequently Asked Questions

1. What is solar curtailment in Australia?

Solar curtailment occurs when generators are required to reduce output due to grid constraints, despite available solar resource. In the National Electricity Market, this is typically driven by congestion, voltage limits, and system security requirements set by Australian Energy Market Operator.

2. Why is solar curtailment increasing in the NEM?

Renewable capacity is growing faster than transmission infrastructure. Many regional networks were designed to serve demand, not export generation, creating bottlenecks as new solar connects.

3. Can battery storage reduce solar curtailment?

Yes, but only when properly designed. Co-located BESS can reduce curtailment by absorbing excess generation and reshaping exports, provided it is engineered around local network constraints rather than generic assumptions.

4. What is Hybrid Energy Yield Assessment (Hybrid EYA)?

Hybrid EYA models solar, battery storage, load, and grid constraints as a single integrated system. It captures real-time interactions that conventional, sequential energy modelling misses.

5. Which regions in Australia experience the highest curtailment?

Curtailment is most severe in constrained regional zones, particularly western New South Wales, north-west Victoria, and parts of South Australia, where congestion and voltage limits are already binding.

6. How can battery charging contribute to curtailment?

During peak solar periods, high battery charging can increase local voltage, reducing allowable export capacity. If the battery fills too early, it may be unavailable when curtailment risk is highest.

7. What is the difference between structural and recoverable curtailment?

Structural curtailment is driven by persistent transmission limits and requires network upgrades. Recoverable curtailment arises from operational constraints and can often be mitigated through storage design and control strategy.

8. How accurate is Hybrid EYA compared to traditional modelling?

Hybrid EYA provides materially higher accuracy in constrained networks by explicitly modelling voltage limits, export constraints, and battery state-of-charge dynamics that standard yield assessments ignore.

9. When should Hybrid EYA be used?

Hybrid EYA is essential when export limits are below peak generation, networks are voltage-constrained, or battery sizing and control materially affect curtailment and revenue.

10. Will transmission upgrades eliminate curtailment in Australia?

Transmission upgrades will help in the medium term, but they won’t arrive fast enough for projects being developed today. Curtailment risk must be managed through intelligent system design in the interim.
