What is this hub?
A sitework calculator hub groups tools for ground preparation, concrete pours, paving, drainage layers, and other exterior construction quantities.
Calculator hub
Sitework Calculators.
Use these sitework calculators to estimate volumes, tonnage, bag counts, base layers, and waste allowances before ordering bulk materials.
Why use these tools?
Sitework mistakes can be expensive because materials are often ordered by the cubic yard, ton, truckload, or pallet. These tools help translate dimensions into practical ordering numbers.
How to choose
Start with the calculator that matches the material being placed. Use concrete for slabs and piers, gravel or road base for compacted layers, sand for bedding, and paver or retaining wall tools when the finished system includes units or blocks.

Common questions
Which sitework calculator should I use first?
Start with the calculator for the main material on the job. For a slab, use the concrete calculator first, then use gravel, sand, or rebar tools for supporting materials.
Do sitework calculators include waste?
Most sitework tools include a waste or overage input. Use a higher allowance for irregular shapes, compacted materials, hand-dug areas, and jobs where delivery shortages would delay the work.
