Frequently Asked Questions
Can I use GroundCalculator offline on a job site?
Yes. Once loaded in your browser cache, all 25 estimators execute 100% of their computations locally without requiring active network connectivity or server roundtrips.
Can I cite GroundCalculator in commercial bids?
Yes. GroundCalculator is free for professional and residential takeoff estimates. We recommend referencing our 10% safety overage model when presenting contractor estimates.
Where do bulk density ranges come from?
Our values are cross-calibrated against state DOT manuals, USDA agricultural extension guides, and bulk supplier weigh tickets.
Do you collect or sell user project data?
Never. We do not require accounts, logins, or emails to calculate. Your dimensions and material inputs never leave your device.
Response Times & Correspondence
Our engineering and editorial review team monitors correspondence Monday through Friday during standard business hours (9:00 AM – 5:00 PM EST). We aim to respond to mathematical inquiries and bug submissions within 2 business days.
Job Site & Civil Engineering Advisory
Please note that while GroundCalculator provides mathematical calculators and extension-sourced density benchmarks, we do not provide on-site civil engineering consulting or structural inspection services. For load-bearing foundation work, retaining walls exceeding standard heights, or municipal permitting, always verify takeoffs with a licensed structural engineer.
