ADA Compliance for Sidewalks,
Curb Ramps, and Pedestrian Infrastructure

Municipal ADA transition plans require a complete inventory of curb ramp conditions, sidewalk compliance status, and a prioritized remediation timeline. AccessTwin™ builds it for you.

The challenge

Transition plan requirements without transition plan data

No Curb Ramp Inventory

Most municipalities cannot document the number of curb ramps in their network, their condition, or which ones are compliant. No inventory means no defensible transition plan.

Transition Plan Gaps

Federal law requires transition plans with timelines and budgets. Without data, you cannot commit to realistic compliance dates or prioritize work by equity and impact.

Complaint-Driven Maintenance

When you have no inventory, work prioritization becomes reactive: lawsuit complaints, council pressure, or the loudest advocacy group, not condition-based or equity-weighted data.

What AccessTwin™ delivers

Your municipal ADA program, from inventory to closeout

Sidewalk and Curb Ramp Inventory

Digitize every curb ramp, sidewalk segment, and pedestrian crossing in your jurisdiction. GPS location, high-resolution photos, physical attributes (width, height, length, slope), surface materials, and baseline condition assessment.

  • Structured inventory of all curb ramps and sidewalk segments
  • GPS coordinates with aerial photo alignment
  • Photo documentation from multiple angles
  • Physical dimensions and material type
  • Export in GIS-compatible formats

Compliance Assessment

Structured inspection protocol covering slope, cross-slope, width, surface condition, detectable warnings, transitions, and signage. Each pad is evaluated against current ADA Standards for Accessible Design (2010 ADA Standards, as amended).

  • Slope and cross-slope measurement (landing pads)
  • Surface roughness and trip hazard assessment
  • Detectable warning (tactile pad) presence and condition
  • Transition quality to adjacent surface
  • Width and approach clearance verification
  • Structured pass/non-compliant/marginal ratings

ADA Transition Plan Support

Track remediation progress against your transition plan timeline. Generate compliance reports, map funding constraints to work phases, and document your progress toward federal compliance targets. Required for DOJ settlement agreements and federal funding applications.

  • Baseline inventory and assessment data
  • Compliance status rollup by district or corridor
  • Workstream-based work planning and tracking
  • Progress reporting against transition plan milestones
  • Cost modeling and budget allocation
  • Multi-year CIP integration

Program Delivery

From assessment through remediation to final closeout. Manage work orders, track construction progress, document QA/QC inspections, and capture as-built conditions. Full chain of custody for every remediation project.

  • Design package generation (retrofit types, specifications)
  • Work order creation and contractor assignment
  • Construction progress tracking and photo logs
  • QA/QC checklists (materials, installation, tolerances)
  • As-built condition documentation
  • Project closeout and compliance sign-off

City-Owned Data

Your inventory, assessment records, and construction documentation stay isolated in your own dataset. You own the data. Export anytime in standard formats (CSV, GeoJSON, PDF reports). No vendor lock-in. Strict per-agency isolation. No surprise licensing costs.

  • Strict per-municipality data isolation — row-level security
  • Dedicated single-tenant deployment available for enterprise & security requirements
  • Full data export in CSV, GeoJSON, and PDF
  • Integration with existing GIS systems
  • Role-based access control (staff, contractors, consultants)
  • Complete audit trail for all changes
  • Perpetual data ownership
Data Security

AES-256 encryption at rest and in transit. Multi-factor authentication for all platform users. Built on SOC 2-compliant cloud infrastructure. Each agency's data is isolated by row-level security with no cross-agency access. Upon contract termination, CIC provides a complete data export and deletes all agency data within 90 days.
