The Challenge
The existing ramp configuration exceeded ADA allowable slope thresholds and did not meet accessible route requirements. The property owner initially anticipated a full switchback ramp reconstruction.
Elevation tolerance across the site was extremely limited, where even minor grading changes risked triggering full ramp construction standards under ADA regulations.
The parking layout and access aisle configuration also required correction to align with dimensional accessibility compliance.
The Solution
Protrk® conducted a 3D laser scan to document existing elevations and slope conditions across the site.
Through detailed elevation analysis, the team identified an alternate approach using the 5% accessible walkway slope allowance, avoiding the need to trigger full ramp reconstruction standards.
Key actions taken:
- Performed 3D laser scanning to capture precise elevation data
- Analyzed slope tolerances and path-of-travel compliance conditions
- Engineered an accessible route using the 5% walkway slope threshold
- Reconfigured parking layout and corrected access aisle dimensions
- Installed compliant striping, signage, and NO PARKING markings
- Refined curb ramp transitions while preserving existing site grading
The Result
The property achieved a fully compliant accessible route from parking to the primary entrance without requiring full ramp reconstruction.
Construction scope was reduced and site disruption minimized while maintaining compliant accessibility.
Project outcomes:
- Delivered an ADA-compliant accessible route from parking to building entry
- Avoided full switchback ramp reconstruction
- Reduced overall construction scope and grading requirements
- Preserved existing site conditions and parking layout efficiency
- Saved the property owner approximately $41,000 in projected reconstruction costs
