Professional Disclaimer

Last Updated: December 22, 2025

⚠️ IMPORTANT NOTICE: This calculator is provided as a preliminary design tool only. All results must be verified by a qualified structural engineer before use in any construction or engineering project.

1. Not Professional Engineering Advice

The Snow & Wind Loads Calculator provides automated calculations based on AS 1170.2 and AS 1170.3 standards. However:

This tool does NOT constitute professional engineering advice
Results are indicative and for preliminary assessment only
This Service does NOT replace the need for a qualified structural engineer
No engineer-client relationship is established by using this Service

2. User Responsibility

By using this calculator, you acknowledge that you are responsible for:

Independent Verification: All calculations must be independently verified
Engineering Judgment: Applying appropriate engineering judgment to results
Code Compliance: Ensuring compliance with all applicable building codes and standards
Site-Specific Factors: Considering site-specific conditions not captured by the calculator
Professional Review: Having a qualified engineer review and approve all final designs

3. Limitations of the Calculator

Users must be aware of the following limitations:

3.1 Assumptions and Simplifications

Calculations are based on standard AS 1170 methodologies
Certain site-specific factors may not be fully captured
Topographic analysis uses automated elevation data which may have limitations
Terrain categories are user-selected and require engineering judgment

3.2 Data Accuracy

Regional wind speed data is based on AS 1170.2 requirements
Snow load regions follow AS 1170.3 classifications
Map data is provided by third-party services (Google Maps Platform)
Elevation data may have accuracy limitations

3.3 Not Suitable For

Final design without professional engineering review
Critical structures or special-use buildings
Structures outside the scope of AS 1170
Structures requiring advanced wind engineering studies

4. No Liability for Design Decisions

The Service provider SHALL NOT be liable for:

Structural failures or damages resulting from use of calculator results
Incorrect design decisions based on calculator outputs
Professional liability claims arising from use of this Service
Loss, damage, or injury resulting from reliance on calculator results
Errors or inaccuracies in calculations or underlying data

5. Professional Engineering Required

For all construction projects, you must:

Engage a qualified structural engineer licensed in your jurisdiction
Have all designs reviewed and certified by the responsible engineer
Comply with local building regulations and approval processes
Obtain necessary building permits and inspections

6. Standards Compliance

While this calculator references AS 1170.2 and AS 1170.3:

Users must verify they are using the current version of the standards
Standards may be updated after this calculator was developed
Local jurisdictions may have additional or modified requirements
Users must consult the official standards documents for complete requirements

7. Educational and Research Use

This calculator may be used for:

Educational purposes and learning about AS 1170
Preliminary feasibility studies
Concept design and early-stage planning
Comparison of different design scenarios

Always transition to formal engineering analysis for actual construction projects.

8. Accuracy Disclaimer

While we strive for accuracy:

No guarantee is made regarding the accuracy of calculations
Software bugs or errors may exist
Results should be cross-checked with manual calculations
Updates or corrections may be made without notice

9. Qualified Professional Definition

A "qualified structural engineer" means:

A professional engineer registered/licensed in the relevant jurisdiction
Possessing expertise in structural engineering and building design
Familiar with AS 1170 and local building codes
Authorized to certify structural designs for building approval

10. Acceptance of Risk

By using this Service, you acknowledge that:

You understand the limitations described above
You accept full responsibility for design decisions
You will engage qualified professionals for final designs
You use this calculator entirely at your own risk

📋 REMEMBER: This calculator is a tool to assist engineers and designers, NOT a replacement for professional engineering expertise. Always consult with qualified structural engineers for building projects.
