Protecting Bay Area Developments from ADA Lawsuits with Precision 3D Data

CASp-ready ramp, landing, cross-slope, threshold, and accessible-route documentation for owners, architects, contractors, developers, and counsel who need regulatory certainty before ADA risk becomes expensive.

CASp-Ready Audits Built on Surgical Precision

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.

Our role is measurement and documentation: 3D scan data, elevation-colored exhibits, slope verification, and survey-grade control that gives CASp consultants, architects, contractors, and attorneys a defensible factual base.

  • 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

Built-Condition Proof

Survey-grade measurements for routes, ramps, and transitions.

Document slopes, landings, thresholds, cross-slopes, and site transitions before issues become rework or claims.

Regulatory Certainty for Bay Area Accessibility Claims

We do not replace your CASp specialist or attorney. We provide the precise 3D measurement record they need: slope data, cross-slope data, landing geometry, transition elevations, and clear exhibits tied to survey-grade control.

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.

Deformation Monitoring

Track structural deformation, settlement, and site movement using a combination of high-density 3D laser scanning and precise survey control.

Forensic Surveying

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