Accessibility Statement
Last updated: May 19, 2026
1. Our commitment
LocusBIM is designed and tested against the Web Content Accessibility Guidelines (WCAG) 2.2 Level AA. This statement applies to the LocusBIM desktop application (Windows, macOS, Linux), the locusbim.com website, and the LocusBIM web tools at pdf.locusbim.com. Verification is continuous, not a one-time audit — automated tests run against the brand color specification on every change before release.
2. Conformance level
WCAG 2.2 — Level AA. Every documented text-on-background pairing in the brand color specification is verified per-theme via the WCAG relative luminance formula, in both dark mode and light mode. Verification is automated and runs on every change before release, so the conformance claim reflects the shipping build rather than a point-in-time audit.
Procurement frameworks this conformance addresses:
- Section 508 (U.S. federal procurement) — Revised 508 standards reference WCAG 2.0 AA. LocusBIM exceeds this with WCAG 2.2 AA.
- EN 301 549 (EU public-sector procurement) — Clause 9 maps to WCAG 2.1 AA. LocusBIM exceeds this with WCAG 2.2 AA.
- Accessibility for Ontarians with Disabilities Act (AODA) — Information and Communications Standards reference WCAG 2.0 AA. LocusBIM exceeds this.
- Accessible Canada Act (ACA) — federal Canadian procurement aligned with WCAG 2.0 AA.
3. What's verified
3.1 Color contrast (WCAG 1.4.3 + 1.4.11)
Every text token paired with every background token in the brand specification is tested against the WCAG luminance threshold for its size class. Primary text clears 4.5:1 (AA normal). Bold or large text clears 3.0:1 (AA large). Graphical elements like icons and borders that carry meaning clear 3.0:1 (WCAG 1.4.11). Both light and dark themes are tested independently.
3.2 Keyboard operation (WCAG 2.1.1)
Every menu, dialog, dropdown, and toggle is reachable and operable from the keyboard. Escape closes any open menu, popover, or modal. Focus rings render at 2 px in the brand copper for unambiguous visibility against both themes.
3.3 Reduced motion (WCAG 2.3.3)
Interface animations are capped at 150 ms and never the only channel conveying meaning. The khatam-pattern indeterminate loader rotates at an accessibility-friendly rate.
3.4 Names, roles, and values (WCAG 4.1.2)
Interactive controls carry proper aria-label / aria-pressed / aria-expanded attributes. Dialogs use role="dialog". Status changes (sync state, AI model loading, license verification) use role="status" so they are announced when they change.
3.5 Component vocabulary
Every form input is a spec-defined component (TextField, NumericStepper, Dropdown, Toggle, SegmentedControl) with consistent behavior across the app. Native <select> is replaced with a custom dropdown that respects keyboard navigation, screen reader announcements, and the spec contrast targets.
4. Known limitations
- Screen reader coverage — narrator support is correct for the spec component library, but the long-tail of dialogs has been spot-checked rather than fully audited. We're tracking this as a planned future sweep.
- Native high-contrast modes — Windows / GNOME high-contrast accessibility modes currently display in the brand palette; native HC overrides are not yet honored. Roadmapped.
- 3D viewport content — geometry colors in the 3D scene reflect the user's model (or use AEC-convention discipline colors). Models with low- contrast geometry against the scene background are the user's content; LocusBIM provides the warm-mid-gray scene background and edge-emphasis options but cannot override the model's authored materials.
- PDF content — PDFs render in their native colors per the spec rule that user content is the user's responsibility for legibility. We provide contrast-respecting markup tools, but the source PDF's contrast is set by the document author.
5. How we verify (continuously)
Accessibility is verified by automated tests that run on every change before release, not by a one-time audit.
- Color usage. Every color in the interface is checked against the approved brand palette, so nothing drifts to an off-spec value.
- Contrast. Every text-on-background combination is verified against the WCAG luminance formula, separately in light and dark mode. A failure blocks the release.
- Consistency. Automated checks catch misuse such as a disabled-control color landing on a body-text label.
6. Voluntary Product Accessibility Template (VPAT)
A VPAT 2.5 RevWCAG2.2 is available on request for procurement teams. Email accessibility@locusbim.com with your RFP number and we will deliver a populated VPAT within 5 business days under NDA if required.
7. Feedback and contact
We treat accessibility gaps as bugs. If you encounter a surface that doesn't meet WCAG 2.2 AA — color contrast, keyboard operation, screen reader, anything — please email accessibility@locusbim.com with the surface (screenshot is helpful), the assistive technology you use (if any), and what you expected. We respond within 2 business days and prioritize the fix in the next release.
