Accessible routes leave very little room for error, and a ramp or sidewalk that misses its slope limits is expensive to fix once the concrete has cured. We design ADA-compliant pedestrian facilities in the public right-of-way, review existing facilities for compliance, and follow the work into construction so the slopes on the plans are the slopes that get built.
What We Deliver
- Curb ramp design for new construction and retrofits, including detectable warning placement.
- Sidewalk grading analysis and pedestrian access route planning, modeled in 3D with the adjacent roadway so ramps and walks tie in cleanly.
- Pedestrian signal replacement design at intersections.
- Temporary pedestrian access routes (TPARs) that keep people moving safely through work zones during construction.
- Compliance reviews of existing pedestrian facilities for public agencies.
- ADA improvement plans for buildings and sites, prepared for contractors or plan reviewers.
Training & Experience
Robert Rippee, PE holds ODOT certification for designing ADA curb ramps and replacement pedestrian signals, and that training also covered temporary pedestrian access routes. We have prepared TPAR sheets for agency review, and we produced ADA improvement plans for a manufacturing building that the City of Sheridan approved.
Compliance is also checked in the field. During construction we measure concrete form slopes before each pour and recheck ramps and sidewalks afterward, which saves time and material and avoids disputes later.
Standards We Work To
Current ADA and PROWAG requirements for accessibility in the public right-of-way, ODOT standard drawings for curb ramps and temporary pedestrian access routes, and local agency requirements.
