2. Local Jobsite & Ground Condition Variations

Material yields, gravel compaction rates, and concrete hydration properties vary based on local humidity, ambient temperature, elevation, subsoil moisture, and excavator equipment. While our calculators incorporate standard ASTM and ACI allowances, actual jobsite conditions may necessitate additional overage allowances.
