Material & project assumptions

Density and bag values are editable planning assumptions. Confirm the product label or supplier specification.

Reinforcement quantities follow your inputs, not a structural design. Base volume excludes its own waste and compaction. Trench fill does not subtract pipe displacement.

Prices are optional. Tax and additional charges are included only when explicitly entered or covered by the saved terms. Placement labor is excluded. Estimates are not supplier quotes.

User-entered supplier prices; delivery and tax require confirmation.

No detailed supplier conditions were saved. Confirm delivery and other charges before ordering.

Supplier order terms

Amounts are flat dollar charges for this order. Leave unknown charges blank; enter zero only when confirmed. Weight limits use your entered density. Choosing another supplier clears these quote fields and the delivery location.

Your entered unit price, rounding, delivery, and short-load assumptions apply. Saved supplier minimums and brackets are not automatically enforced in manual quote mode.

Supplier prices & delivery rules

Set an optional weight capacity under Supplier order terms; loads use whichever volume or weight limit is lower. Confirm the payload limit and material density with your supplier. Short-load fees apply to each load below your threshold. Base material and rebar costs are excluded.

Entered delivery fees: $0.00 · Short-load fees: $0.00

Use a researched supplier price

These are product-specific examples, not regional averages. Applying one sets the listed unit rate. Review delivery, minimum-order and density terms before using the totals. Editing the unit rate switches to manual quote mode.
