Fixing an access problem on a drawing takes minutes. Fixing it after construction can mean demolition. An accessibility design review checks plans at each stage, so that errors are found while changes cost almost nothing.

Review at Every Stage, Not Just at the End

Most projects pass through concept, schematic design, design development and construction documents. Each stage raises different questions. At concept, the issue is the site approach, entrance location and vertical circulation. In schematic, it is room sizes and layouts. At development, it is door hardware, finishes and signage.

A single review at the end finds problems after structure and services are fixed. Staged reviews keep each correction small.

Review meetings work best when they are short and focused. An hour on a defined set of drawings is more productive than a half-day walk through everything.

Use the early stages to test big ideas, such as whether regrading the site can remove a level change entirely instead of adding a ramp. Those choices are almost impossible to reverse later.

What Reviewers Look For on the Drawings

Reviewers check the plan against the governing code and then test the layout for usability. Typical items include:

• Clear floor space beside doors, at counters and in washrooms.

• Turning space for wheelchairs, usually around 1500 mm, subject to local code.

• Step-free routes that connect every public space, not just the main entrance.

• Reach heights for controls, handles and fixtures.

• Contrast and tactile information in signage and stairs.

Reviewers also read the specification, not just the drawings. A hardware schedule that lists knob-style handles undermines an otherwise good layout, and a lighting schedule can reveal glare or dark corridors.

They check furniture layouts too, since fixed seating or planters can narrow routes. An accessibility review that looks only at the building shell will miss those conflicts.

Common Errors That Keep Appearing

Some mistakes recur across projects. A washroom door swings into the turning circle, which leaves no space to manoeuvre. A lift is shown but sits behind a locked corridor. A ramp meets the code slope but ends at a door with no landing. Signage is specified in a low-contrast finish chosen for looks.

Most of these come from drawings coordinated by different disciplines. A universal design consultant who reads the whole set can catch conflicts between architectural, interior and landscape drawings.

Another recurring issue is the gap between drawings and what gets built. Site substitutions, like a different door closer or a revised threshold, can break compliance without anyone noticing, so ask for a site check before handover.

Make the Review Part of Your Workflow

Use a shared comment log with a number, a location, the issue, the recommendation and a status. The design team responds to each item, and the reviewer confirms closure at the next stage. This creates a record that can support permit submissions or later disputes.

Book review dates in the programme at the start. When they are treated as milestones, they are far less likely to be skipped under schedule pressure.

Give the reviewer the full drawing set, including consultants' drawings. Parts of a route are often shown only on engineering or landscape sheets.

Where budgets allow, bring in a universal design consultant for projects with complex public use, such as transit hubs or schools, since the range of users is wider.

Keep the log after handover. Facilities teams can use it to understand why a feature exists before someone removes it during a future refit.

Conclusion

Staged reviews, a clear comment log and attention to common drawing errors keep access problems from reaching the site. A universal design consultant can add value by reviewing across disciplines and challenging assumptions early. If you are planning a project, consider scheduling your first accessibility design review before the layout is fixed.

FAQs

1. When should the first review happen?

At concept stage, before the building layout is fixed. Changes at this point cost little.

2. Does a design review replace a site inspection?

No. It catches issues on drawings, and a site check afterwards confirms the built result matches the design.

3. Who should attend the review meeting?

The architect, interior designer, project manager and the reviewer, with engineers joining when their systems are affected.

4. What should a good review comment look like?

It names the location, the problem, the reason and a suggested fix, so the designer can act without a follow-up meeting.

5. How much time should we allow?

About a week for a typical review round, longer for large drawing sets.
