Intellectual Property
All content on the Sites — including text, graphics, images, technical documentation, and software — is the property of CS3 / Girder-Slab or its licensors and is protected by applicable intellectual property laws.
The CS3 Girder-Slab structural system, including its design, specifications, and engineering methodology, is proprietary. Nothing on these Sites grants you a license to reproduce, manufacture, or commercialize any aspect of the CS3 Girder-Slab system without our express written consent.
You may download or print materials from the Sites for your own professional reference and evaluation purposes. You may not reproduce, distribute, or publish this content for any other purpose without prior written permission from us.
Engineering Calculator — Important Disclaimer
The engineering calculator at app.girder-slab.com is provided as a tool to assist qualified professionals in preliminary evaluation of the CS3 Girder-Slab system. Access is restricted to approved users.
Calculator results are for preliminary estimation purposes only. They are not a substitute for a complete structural engineering analysis and must be reviewed and verified by a licensed engineer of record before use in any project design, permit submittal, or construction document.
The calculator does not account for all project-specific conditions, local code requirements, site conditions, loading combinations, or other factors that a licensed engineer must evaluate. Output from the calculator should be treated as a starting point for professional engineering judgment — not as a final engineering determination.
By using the calculator, you acknowledge that you understand these limitations and that you are responsible for ensuring that any designs or specifications derived from calculator output are reviewed, validated, and stamped by a licensed professional engineer appropriate for your jurisdiction.
Limitation of Liability
To the fullest extent permitted by applicable law, CS3 / Girder-Slab and its owners, employees, and agents shall not be liable for any direct, indirect, incidental, consequential, or special damages arising out of or in connection with your use of the Sites or reliance on any information or tools provided through the Sites, including the engineering calculator.
The Sites and all content and tools are provided “as is” without warranties of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, or accuracy. We do not warrant that the Sites will be uninterrupted, error-free, or free of harmful components.
We are not responsible for any project outcomes, engineering decisions, or construction results that arise from use of information or tools provided on the Sites. Professional engineering judgment is always required.
Third-Party Links
The Sites may contain links to third-party websites for your convenience. We do not control those sites and are not responsible for their content, privacy practices, or availability. Linking to a third-party site does not imply our endorsement of it.
Privacy
Your use of the Sites is also governed by our Privacy Policy, which is incorporated into these Terms of Use by reference. Please review it to understand how we collect and use information.
Governing Law
These Terms of Use are governed by and construed in accordance with the laws of the State of California, without regard to its conflict of law provisions.
