IMPORTANT NOTICE: READ CAREFULLY BEFORE USING THIS SERVICE
This calculator is a computational tool only and does NOT constitute professional engineering advice, design services, or a substitute for qualified geotechnical engineering judgment. Use of calculation results without proper professional review may lead to catastrophic failures, injuries, or death.
1. Nature of the Service
This Rock Bolt Design Calculator is a computational tool that performs mathematical calculations based on Australian Standards (AS4678-2002, AS5100). The Service:
- Provides numerical calculations based on user-supplied input parameters
- Calculates bar-grout and grout-rock interface capacities
- Determines working loads and bond lengths for rock bolts
- Facilitates batch calculations for parametric studies
The Service is NOT a geotechnical engineering firm and does NOT provide professional engineering services, consulting, design, or recommendations.
2. Professional Responsibility and User Liability
🔒 YOU ASSUME FULL AND EXCLUSIVE RESPONSIBILITY 🔒
BY USING THIS SERVICE, YOU EXPRESSLY ACKNOWLEDGE AND AGREE THAT YOU ARE THE SOLE PARTY RESPONSIBLE FOR:
- ALL ENGINEERING DECISIONS: Every design, analysis, recommendation, and professional judgment based on or influenced by Service outputs
- INPUT ACCURACY: All data, parameters, values, and assumptions you enter into the calculator
- OUTPUT VERIFICATION: Independent verification of all calculation results before use
- PROFESSIONAL REVIEW: Ensuring all outputs are reviewed by qualified, licensed geotechnical engineers
- SITE-SPECIFIC CONDITIONS: Accounting for actual geological conditions, construction practices, and local requirements
3. Limitations of Calculations
The calculations provided by this Service have inherent limitations:
- Based on idealized theoretical models that may not reflect actual field conditions
- Do not account for construction quality, installation procedures, or workmanship
- Do not consider time-dependent effects, corrosion, or long-term degradation
- Do not replace site-specific geotechnical investigations
- May not be suitable for all geological conditions or rock types
- Reduction factors and safety factors must be verified for specific project requirements
4. Required Professional Oversight
ALL outputs from this Service MUST be:
- Reviewed and verified by a qualified, licensed geotechnical engineer
- Validated against site-specific geological data and ground conditions
- Checked for compliance with local building codes, regulations, and standards
- Confirmed appropriate for the specific project requirements and loading conditions
- Documented as part of a complete engineering design process
5. No Warranty
THE SERVICE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, RELIABILITY, OR NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE CALCULATIONS WILL BE ERROR-FREE OR SUITABLE FOR ANY PARTICULAR APPLICATION.
6. Limitation of Liability
IN NO EVENT SHALL GEOTECHNICAL DESIGNS, ITS OWNERS, EMPLOYEES, OR AFFILIATES BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO YOUR USE OF THIS SERVICE, INCLUDING BUT NOT LIMITED TO STRUCTURAL FAILURES, PROPERTY DAMAGE, PERSONAL INJURY, OR DEATH.
