# Grading & Earthwork
**Grading** reshapes the land so water drains correctly and the site is buildable. The civil engineer designs proposed contours; the contractor cuts and fills to match.
## Key ideas
- **Cut and fill** — soil removed from high spots ("cut") is used to build up low spots ("fill"). A **balanced site** (cut ≈ fill) avoids costly importing or hauling of dirt.
- **Slopes & pads** — building pads are set at the right elevation; slopes are kept stable and within code (often 3:1 or flatter).
- **Compaction** — fill must be placed and compacted in lifts to support pavement and foundations (per the geotech report).
## Cost drivers
- Importing or exporting dirt is expensive — designers work hard to **balance earthwork**.
- Rock, bad soils, and high groundwater drive cost.
- Tight, steep, or wet sites cost more to grade.
**Takeaway:** Balance cut and fill — moving dirt on or off site is where earthwork money is won or lost.
