Reponse rapide

A 24 in rise ramp with 24 ft of horizontal run, 4 ft clear width, two 5 ft by 5 ft landings, 4 in average thickness, and 10% waste needs about 1.98 yd3 of concrete. The slope preview is about 1:12. This is a material and quote planning check, not ADA, permit, inspection, or code approval.

Convertir la pente et les yards de rampe en checklist de préparation de devis

Most ramp calculators stop at slope or concrete volume. Ramp work also needs landings, thresholds, surface texture, drainage, handrails, edge protection, access, permits, inspections, and a clear planning-only boundary before the number is quote-ready.

Élément de portée	Statut	Quoi verifier
Slope ratio and rise/run	confirm	The planning slope is about 1:12.0. Still confirm cross slope, landings, and local code separately.
Landings, turns, and thresholds	confirm	Landing concrete is included. Confirm top, bottom, intermediate, threshold, and sidewalk tie-in dimensions.
Surface texture and drainage	ask	Ask who owns broom direction, slip resistance, cross slope, drainage discharge, ponding corrections, and curing protection.
Handrails and edge protection	ask	Rail coordination, embeds, sleeves, edge curbs, guards, and correction work may sit outside concrete material pricing.
Demolition, base, and compaction	ask	Confirm removal, excavation, base stone, compaction, unsuitable soil, haul-off, and cleanup as written line items.
Access and placement method	ask	Confirm chute reach, pump or buggy cost, wheelbarrow route, wait time, washout, protection, and finishing crew timing.
Permit and inspection responsibility	ask	Public-access ramps can require permits, inspections, plan review, and written responsibility for corrections.
Installed quote per square foot	confirm	Installed quote normalizes to about $64.92/sq ft. Compare this against material-only concrete plus scope lines.

1Does the quote state total rise, total horizontal run, ramp width, and the 1:12.0 planning slope?

2Are top, bottom, intermediate, switchback, doorway, threshold, and sidewalk tie-in landings included?

3Who owns handrails, embeds, edge protection, surface texture, drainage, cross slope, and ponding corrections?

4Are demolition, base prep, compaction, forms, reinforcement, delivery access, washout, cleanup, permits, and inspections written down?

Formule

Pente de rampe et longueur de tablier incliné

Slope percent = rise / horizontal run x 100Slope = 2.0000 / 24.0000 x 100 = 8.33%; planning ratio = 1:12.00Sloped ramp length = sqrt(run^2 + rise^2) = 24.0832 ft

Volume de béton rampe et palier

Ramp area = sloped length x ramp width; landing area = landing count x landing length x landing widthGross volume = (96.33 + 50.00) x 0.3333 = 48.7776 ft3 (1.8066 yd3)

Utiliser area cost as a quote check

Material-only cost per square foot helps separate concrete quantity from demolition, forms, rail coordination, surface texture, drainage, permits, inspection corrections, and cleanup.

Mesure Pases

Measure total rise from finished low point to finished high point, not from rough subgrade.
Use horizontal run for slope, then let the calculator convert it to sloped ramp deck length for concrete volume.
Add every landing that is part of the concrete scope, including switchback, door, sidewalk, and transition landings.
Keep material-only concrete cost separate from rails, demo, base prep, forms, inspections, and corrections.

Planification Limite

The slope preview is a math check, not an accessibility approval.
Confirm ADA, local code, landings, cross slope, handrails, edge protection, surface texture, and permits separately.
Ask who is responsible for inspection corrections before approving a ramp quote.
For structural or public-access work, get qualified local review before construction.

Rampe Devis Portee Verificationlist

Portée	Pourquoi c est important	Demander avant de signer
Rise and run	Slope drives ramp length, landing count, handrail scope, and available site footprint.	Does the quote list total rise, run length, slope ratio, and where landings occur?
Landings and turns	Top, bottom, and intermediate landings add area, forms, transitions, and finish work.	Are all landings, switchbacks, door thresholds, and sidewalk tie-ins included?
Mains courantes et protection des bords	Railings, embeds, sleeves, edge curbs, and guards may be separate from concrete.	Are rails, anchors, embeds, edge protection, and final corrections included or excluded?
Surface and drainage	Texture, cross slope, low spots, and water discharge affect safety and inspection risk.	Who is responsible for broom direction, slip resistance, drainage, and ponding corrections?
Demo and base prep	Existing steps, walks, asphalt, landscaping, and unsuitable base can dominate the installed price.	Are demolition, excavation, base stone, compaction, haul-off, and cleanup written down?
Permits and inspections	Accessibility work may require plan review, inspections, or corrections.	Who handles permits, inspection scheduling, local accessibility requirements, and rework?
Delivery and placement	Long ramps, tight entrances, or back-yard access can require pump, buggy, chute extensions, or extra labor.	Does the quote include access limits, pump/buggy cost, wait time, washout, and protection?

Guide d achat et de devis pour rampe beton

Use this concrete ramp calculator when the search intent is slope, rise, run, landings, and concrete material quantity. For a flat patio, pad, or sidewalk, use the concrete slab calculator instead.

For ADA or commercial ramp planning, read the ADA ramp concrete cost guide, compare delivery in the ready-mix vs bags calculator, and review supplier or contractor scope in the concrete quote reviewer.

Questions frequentes

How do I calculate concrete for a ramp?

Measure horizontal run, total rise, ramp width, average thickness, and landing area. The calculator uses sloped ramp length for the ramp slab, adds flat landings, then applies waste to estimate cubic yards, bags, and material cost.

Does this concrete ramp calculator verify ADA compliance?

No. It shows slope math and concrete quantity only. ADA, local code, landings, handrails, cross slope, edge protection, drainage, permits, inspections, and structural details must be confirmed with qualified local professionals.

What does a 1:12 ramp slope mean?

A 1:12 planning ratio means 12 units of horizontal run for 1 unit of rise. This calculator can show whether your entered layout is steeper or flatter than that planning check, but it does not approve the layout.

Should ramp landings be included in the concrete volume?

Yes, when the landings are part of the same concrete scope. Add the top, bottom, and intermediate landings so the volume and quote comparison include the full pour area.

Why compare ramp cost per square foot?

Ramp bids often include far more than concrete: layout, demolition, forms, base prep, reinforcement, texture, drainage, rail coordination, inspections, and cleanup. Cost per square foot helps compare material-only and installed quotes without confusing them.
