Legal & Material Disclaimer

Important notice regarding the limitations of calculations, estimations, and material schedules on buildercalc.org.

1. General Planning & Estimation Only

All calculation results are estimates intended for planning and drafting support only. Real-world construction, electrical sizing, and structural loads are highly dependent on site conditions, regional variances, and installation factors that automated tools cannot evaluate.

2. Professional & Local Code Validation

Before purchasing materials, cutting lumber, or pouring concrete:
• Verify calculations against regional building codes (IRC, ACI 318, ASTM, NEC).
• Cross-reference calculations with materials manufacturers' specifications.
• Verify designs with a qualified local contractor or professional engineer.

3. Limitation of Liability

buildercalc.org, its operators, and developers assume no liability for material shortages, construction defects, structural failures, or financial losses resulting from the use of calculations or data on this site.
