Terms of Service

1. Acceptance of these terms

By accessing tension1.com (the "Site"), operated by Tension One LLC, you agree to these terms. If you do not agree with them, do not use the Site. You must be at least eighteen years old, or the age of majority where you live, to use the Site or to contact us through it.

2. What the Site provides

The Site publishes technical articles, guides and resources on post-tension concrete, and presents the services offered by Tension One LLC. Content is informational. It does not create an engineer-client relationship, and it is not a substitute for the review, approval and seal of a licensed Professional Engineer. The limits of this are set out in the disclaimer, which forms part of these terms.

3. Use of the Site

You agree not to:

• attempt to gain unauthorized access to the Site, its database or its administration area;
• interfere with the operation of the Site, including by automated scraping that degrades its availability;
• submit content through our forms that is unlawful, abusive or deliberately misleading;
• use the Site to distribute malware or to attempt to inject code into it.

4. Intellectual property

The articles, guides, drawings, diagrams and other original material published on the Site belong to Tension One LLC unless credited otherwise. You may quote a short extract with attribution and a link to the source page. Reproducing an article in full, republishing it elsewhere, or using it to train a commercial model, requires written permission.

Standards referenced on the Site, such as ACI and PTI documents, belong to their respective publishers. We cite them, we do not reproduce them, and we do not link to any source distributing them unlawfully.

5. Digital products and resources

Ebooks, guides, spreadsheets and templates published by Tension One LLC are sold and delivered through third-party platforms, not through this Site. Your purchase forms a contract with the platform concerned, and its terms govern payment, delivery, licensing, refunds and customer support. We are not a party to that contract and cannot process a refund on a platform's behalf.

A resource downloaded free of charge from the Site is licensed to you for your own professional use. It remains our property, and it may not be resold, republished or redistributed.

Every calculation sheet and template is supplied with its assumptions stated. Checking that those assumptions apply to your project, and verifying the output, is your responsibility and that of the engineer of record.

6. Paid services

Design support and consulting work is governed by the written scope and terms agreed for each engagement, not by this page. Where the two differ, the engagement agreement prevails. Deliverables are issued as independent technical support and are not sealed. We make no guarantee as to any particular outcome, including approval by a reviewer or an authority having jurisdiction.

7. Third-party links and purchases

The Site links to third-party resources, some through affiliate links disclosed in our affiliate disclosure. Purchases made on a third-party site are governed by that site's own terms. We are not a party to them.

8. Limitation of liability

The Site and its content are provided as they are, without warranty of any kind, express or implied, including any implied warranty of merchantability or fitness for a particular purpose. To the extent permitted by law, Tension One LLC is not liable for any indirect, incidental, special or consequential loss, nor for any loss or damage arising from the use of the Site or from reliance on its content. Nothing here limits liability that cannot be limited by law.

9. Availability

We aim to keep the Site available, but we do not guarantee uninterrupted access. Content may be added, changed or removed at any time without notice. We are not responsible for any failure or delay caused by events outside our reasonable control, including network failures, hosting outages and acts of nature.

10. Privacy

How the Site handles personal data is described in our privacy policy, which forms part of these terms.

11. Copyright complaints

If you believe material on the Site infringes your copyright, send us a notice through the contact page identifying the work concerned, the page where it appears, and your contact details, with a statement that you are the rights holder or authorized to act for them. We investigate and remove infringing material where the claim is substantiated.

12. General

If any provision of these terms is held unenforceable, the rest remains in force. Our failure to enforce a provision is not a waiver of it. These terms, together with the disclaimer, the privacy policy and the affiliate disclosure, are the entire agreement between us regarding your use of the Site. You may not assign your rights under them; we may assign ours in connection with a transfer of the business.

13. Governing law

These terms are governed by the laws of the State of Texas, United States, without regard to conflict of law rules. The courts located in Dallas County, Texas have exclusive jurisdiction over any dispute arising from them, and you consent to that jurisdiction.

14. Changes to these terms

If these terms change, the revised version is published on this page with a new revision date. Continued use of the Site after that constitutes acceptance of the revision.

15. Contact

Questions about these terms can be sent through the contact page, or to Tension One LLC, Dallas, TX, +1 469-629-7327.
