3. Acceptable Use

You agree to use the Site only for lawful purposes and in accordance with these Terms. You agree not to:

• Use the Site in any way that violates applicable federal, state, local, or international law or regulation.
• Attempt to interfere with, disrupt, or compromise the Site's security, servers, or networks.
• Use any automated means (bots, scrapers, crawlers) to access or extract data from the Site in a manner that imposes an unreasonable load on our infrastructure.

4. No Warranty and Disclaimer

Important: All calculators and content on PavementCalculator.com are provided "as is" and for informational purposes only. While we strive for accuracy using industry-standard formulas and engineering principles, we make no warranties, express or implied, regarding the accuracy, completeness, reliability, or fitness for a particular purpose of any calculation or content.

Specifically:

• Calculator results are estimates based on standard engineering formulas and default material densities. Actual material requirements vary based on site-specific conditions including but not limited to: subgrade quality, compaction rates, waste factors, material variability, weather conditions, and installation technique.
• Construction projects involve inherent risks. Material estimates should be independently verified by a qualified professional before ordering materials or commencing work.
• Cost estimates are approximations based on average market rates and do not account for regional price variations, bulk discounts, seasonal fluctuations, or special-order materials.
• Structural calculations (foundations, retaining walls, beams, slabs) must be reviewed and approved by a licensed structural engineer for any load-bearing or safety-critical application.

5. Limitation of Liability

To the fullest extent permitted by applicable law, PavementCalculator.com and its owners, operators, employees, and affiliates shall not be liable for any direct, indirect, incidental, special, consequential, or punitive damages arising out of or relating to your use of, or inability to use, the Site. This includes, but is not limited to:

• Material shortages, overages, or incorrect material orders.
• Project delays, cost overruns, or budget miscalculations.
• Structural failures, property damage, or personal injury.
• Loss of profits, business interruption, or reputational harm.
• Errors, omissions, or inaccuracies in calculator outputs or educational content.

Your sole remedy for dissatisfaction with the Site is to discontinue use. Some jurisdictions do not allow the exclusion of certain warranties or limitation of liability, so some of the above exclusions may not apply to you.

6. Professional Consultation Requirement

PavementCalculator.com is a planning tool, not a substitute for professional judgment. You are strongly advised to:

• Consult a licensed civil or structural engineer for any structural designs, load-bearing calculations, or safety-critical applications.
• Consult a qualified contractor or estimator for project-specific quantity takeoffs and cost estimates.
• Obtain appropriate permits and comply with local building codes before beginning any construction project.
• Have soil conditions assessed by a geotechnical engineer for foundation, retaining wall, and pavement design.
