41 Free Construction How-To Guides and Reference Charts — Field Notes From a 15-Year Engineer (2026)

35 practical field guides plus 6 dedicated reference charts & formulas (density, tonnage, curing, gradation) from 15 years of construction engineering experience. Each page cites ACI, ASTM, AASHTO, ICC IRC, NAPA or AWC standards alongside on-site observations from residential, commercial and municipal projects.

The calculators give you the numbers. The guides explain why those numbers matter. Each guide is written by Sarah Miller from actual jobsite experience — not rewritten spec sheets. Start with the guide closest to your project and cross-reference with the relevant calculator.

Frequently Asked Questions

How are these guides different from the calculators?

Calculators give you numbers; guides explain the why. Guides cover decision-making, tradeoffs, field issues, and real examples that don't fit in calculator pages. Think of them as the field notebooks behind each calculator.

Who writes the guides?

Sarah Miller, construction engineer with 15 years of field experience. Each guide cites published engineering standards (ACI, ASTM, AASHTO, IRC) alongside field observations.
