ConstructionCalc provides free, browser-based construction reference calculators, including the Excavation Slope Calculator. The Site is intended to provide general planning estimates and educational information about construction safety concepts referenced from publicly available regulatory standards such as OSHA 29 CFR 1926 Subpart P.
All calculations are performed locally in your browser. We do not store, transmit, or retain any values you enter into the calculator.
3. No Professional, Legal, or Safety Advice
Nothing on this Site constitutes professional engineering advice, legal advice, safety advice, or OSHA compliance guidance. The calculators and content on this Site are provided solely for general informational and planning estimation purposes.
The results produced by this Site's calculators:
- Are estimates only and may not reflect actual site conditions
- Do not account for all variables that affect excavation safety, including but not limited to groundwater, surcharge loads, adjacent structures, equipment vibration, soil fissures, and weather conditions
- Do not replace the classification and judgment of a qualified OSHA competent person
- Do not replace the design and approval of a licensed professional engineer
- Do not constitute compliance with any federal, state, or local law or regulation
- Do not replace a site-specific safety plan or hazard analysis
Before excavating or implementing any protective system, you must consult a qualified competent person as defined by OSHA 29 CFR 1926.650, comply with all applicable OSHA standards and local regulations, and obtain any required permits or engineering approvals. For excavations deeper than 20 feet, a protective system must be designed by a registered professional engineer.
