Wheelchair Ramps (U02)

Wheelchair ramps provide essential access – required for mobility devices and mandated by ADA for commercial properties in Utah.

This BidScope covers ramp types (permanent, modular, portable), materials (wood, aluminum, concrete), slope requirements (1:12 ADA standard, steeper allowed for residential), and installations (residential, commercial, temporary).

Learn ADA requirements: slope ratio (1:12 maximum rise-to-run, 1 inch vertical for every 12 inches horizontal), landing size (60×60 inches minimum at top, bottom, direction changes), handrails (34-38 inches height, both sides if rise over 6 inches, graspable diameter, extensions 12 inches beyond), width (36 inches clear minimum), edge protection (2-inch curb or barrier prevents wheels going off).

Understand material options: wood (economical, treated lumber, requires maintenance, 5-10 year lifespan), aluminum (lightweight, weather-resistant, modular assembly, 15-20+ years), concrete (permanent, durable, most expensive, custom pour), steel (commercial grade, powder-coated, very durable).

Master slope calculations: measure vertical rise (from ground to door threshold), calculate run (rise x 12 for ADA, or rise x 8-10 for steep residential), landings (every 30 feet maximum, at turns and top), switchbacks (for long rises, multiple ramps with landings between).

Navigate residential versus commercial: residential (steeper slopes acceptable 1:8 to 1:10, less strict handrails, homeowner preference), commercial (ADA compliance mandatory, inspections required, lawsuit liability if non-compliant), Veterans Affairs (funding for eligible, stricter requirements than basic residential).

Learn permanent versus modular: permanent (concrete or built wood, site-specific, highest cost, best aesthetics), modular (aluminum sections, adjustable to site, lower cost, professional appearance, relocatable), portable (threshold ramps or folding, temporary access, limited height).

Understand surface requirements: non-slip (texture critical, wet conditions Utah rain and snow), drainage (prevent water pooling, ice formation hazard), maintenance access (cleaning, snow removal), weathering (sun UV, freeze-thaw cycles).

Know installation challenges: frost heave (footings below frost line 30-36 inches Utah, prevent seasonal movement), drainage (water flow around ramp, not under), existing landscape (grading, retaining walls, plants), door swing (clearance on landing, outward swing requires larger landing).

Navigate handrail requirements: height (34-38 inches measured from ramp surface), continuous (no gaps or interruptions, extensions beyond top and bottom), graspable (1.25-2 inch diameter round or oval), mounting (secure to structure or posts, withstand 200+ pound force).

Learn permitting and codes: building permits (required for most permanent ramps, inspection for compliance), ADA (commercial must meet, residential encouraged for resale and visitors), HOA approval (some developments restrict or require aesthetic standards), historic properties (special considerations for appearance).

Calculate typical costs: wood ramp installed $100-150 per linear foot, aluminum modular $150-250 per linear foot, concrete $200-400+ per linear foot, portable threshold ramp $100-500, professional design and engineering $500-2,000, permits and inspections $100-500.

This tool ensures wheelchair ramps meet code, accessibility needs, and safety requirements in Utah.
