Accessible Route or Ramp?
Say the building finished floor elevation is 401' - 6 1/4" and the grade at the parking space is 400.14'. The sidewalk between the parking space and the front door has a distance of 30'. Would this be considered an accessible route or a ramp with handrails?
|
|
Definition
First step is to know that in order for it to be an accessible route the slope must be less than 5%.
Bldg Elevation in Feet
1/4" = 0.02'
6" = 0.08*6 = 0.48'
401' + 0.50' = 401.50'
Get the Height Difference
401.50' - 400.14' = 1.36'
Get The Slope
1.36' / 30' x 100 = 4.53 %
4.53% < 5% therefore it is an accessible route.

Convert Inches to Decimal Feet
6" = 6x0.08 = 0.48'
Find Volume
60'x30'x0.48'=864 CF
Convert To CY
864 CF / 27 = 32 CY
Area of Semi-Circle
A=1/2 pir^2
A=0.5 x 3.14*15^2
A=353.43 SF
Find Volume
V=353.43 SF * 0.48 FT
V=169.64 CF
Convert
169.64 CF / 27 = 6.28 CY
ADD
32 CY + 6.28 CY = 38.28 CY
But buy (5% more for waste) total 40 CY |
