Estimacion en vivoBase prep + mix decision
Check gravel, self-mix, bags, and quote lines before ordering
This is the shed-base layer competitors usually skip. It keeps the concrete result, then screens the 4 in gravel base, bagged dry load, 1:2:3 site-mix screen, ready-mix trigger, and granular base removal and compaction cost lines.
Keep granular base removal and compaction cost separate from the concrete order before approving a shed-pad quote.

| Decision row | Planning value | What to verify |
|---|---|---|
| Concrete pad | 1.09 yd3 with waste | Use the finished formed pad size, not only the shed catalog footprint. |
| 4 in gravel base | 1.09 yd3 / 1.63 tons | Keep granular base removal and compaction cost separate from concrete. |
| Bagged mix load | 49 80-lb bags / 3920 lb dry mix | Pallet-scale lifting and finish timing need a store delivery or truck quote. |
| 1:2:3 site-mix screen | 8 cement bags + 0.56 yd3 sand + 0.84 yd3 aggregate | Use only as a planning boundary; real mix design depends on local materials and strength. |
| Quote scope | Bag delivery, mini-mix, or short-load comparison | Ask for base prep, concrete, access, finish, anchors, cleanup, and exclusions in writing. |

An 8 ft x 10 ft shed base at 4 in thick with 10% waste needs about 1.09 yd3, or about 50 80 lb bags. A 10 ft x 12 ft base is about 1.63 yd3 and 74 80 lb bags; a 12 ft x 16 ft base is about 2.61 yd3 and 118 80 lb bags.
Shed base install scope
Turn shed pad bags into a site-ready plan
Shed calculators usually stop at pad size and bag count. This layer keeps the concrete math, then checks the details that decide whether the shed base will actually work: manufacturer base size, overhang, gravel base, drainage, ramp landing, anchors, backyard access, and bag staging.

| Scope check | Why it matters |
|---|---|
| Finished pad dimensions include shed manufacturer base size, doorway clearance, and overhang. | A shed model footprint is not always the finished concrete pad size. |
| Excavation, gravel base depth, compaction, drainage, and moisture control are specified. | Shed base failures often start with water, soft soil, or missing compaction. |
| Ramp landing, mower entry, anchor layout, reinforcement, and edge forms are separated. | Doorway and mower access can add a separate pour section. |
| Backyard access, bag staging, mixer location, wheelbarrow route, and washout are planned. | Small pads can still fail on access, mixing pace, and staging. |
