THE SHORT ANSWER
How to Estimate a Wheelchair Ramp
A 24 in rise, 4 ft wide aluminum ramp with permit and 16 labor hours at $65 totals about $8,490.
Measure the rise first
The rise sets the ramp length at the code slope. Measure from the landing to the top of the step or threshold.
- Vertical rise
- Ramp width
- Wood vs aluminum
- Permit
Apply the 1:12 slope
For every unit of rise you need twelve units of run. A taller rise means a longer ramp, more material and more support posts.
Wood vs aluminum
Wood ramps are cheaper but need footings, framing and maintenance. Aluminum ramps install faster, last longer and cost more per square foot.
Factor in permits and landings
A permit may be required, and landings at top and bottom are mandatory for safety. Include both in the bid.
