ADA Compliance & Ramp Verification Surveys

Reduce accessibility risk with precise measurements of ramps, landings, routes, slopes, cross-slopes, thresholds, and site transitions. We provide survey-grade documentation that helps architects, engineers, contractors, owners, and counsel evaluate built conditions.

Measure Accessibility Conditions Before They Become Claims

ADA risk often lives in small differences: ramp slope, cross-slope, landing size, threshold transitions, parking grades, and route continuity. We document the built condition clearly so your technical and legal teams can make informed decisions.

  • Ramp slope and cross-slope verification
  • Accessible route and landing documentation
  • As-built exhibits for design teams or legal review
  • Construction-phase checks before liability compounds
  • Clear measurements tied to survey-grade control

Common ADA Survey Areas

Entrance ramps

Landings

Parking access aisles

Sidewalk transitions

Thresholds

Accessible routes

Tenant improvements

Post-construction punch lists

1

Compliance Targets

We confirm the areas to document: entrances, ramps, parking, sidewalks, tenant improvements, or post-construction punch items.

2

Field Measurement

We capture elevations, slopes, transitions, clearances, and the surrounding control needed to evaluate existing conditions.

3

As-Built Exhibits

We prepare clear exhibits and data your architect, engineer, contractor, or attorney can use for decision-making.

4

Correction Support

If remediation is needed, our data helps teams design and verify fixes before closeout or dispute escalation.

ADA Compliance FAQ

We provide precise survey documentation of built conditions. Architects, accessibility specialists, inspectors, or counsel can use that data to evaluate compliance requirements.
Survey before closeout, after concrete placement, during due diligence, or any time there is a dispute about slopes, landings, thresholds, or accessible path conditions.
Yes. We can prepare clear measurement exhibits and coordinate with attorneys or experts when ADA-related site conditions are part of a claim.

3D Scanning

Capture existing conditions once and give every stakeholder a reliable source of truth.

Monitoring

Track structural movement and site changes with precision monitoring surveys.

Forensic Surveying

Expert investigation and analysis of boundary disputes, encroachments, and property line discrepancies for legal proceedings.
