1. Pre-Design Stage
- Needs Assessment: Engaging in discussions with stakeholders, particularly those with disabilities and elderly users, to understand diverse needs and requirements.
- Site Analysis: Evaluating the site for topographical challenges, identifying existing barriers, and considering local climatic conditions to inform design features.
- Regulatory Review: Familiarizing oneself with pertinent accessibility codes and guidelines such as the NBC (National Building Code) and any relevant Universal Design standards to ensure adherence during the design phase.
2. Conceptual Design Stage
- Inclusive Planning: Developing layouts that support wheelchair accessibility with appropriate turning radii, rest areas, and clearly defined pathways.
- Design Charettes: Conducting collaborative workshops that bring together multidisciplinary teams to brainstorm and discuss inclusive design strategies.
- Use of Assistive Tools: Implementing simulation tools or virtual reality (VR) walkthroughs to test designs with diverse user scenarios.
3. Design Development Stage
- Detailing UD Features: Incorporating essential features like automatic doors, appropriate rail heights, audio signage, and clear, high-contrast visuals in the design.
- Prototype Testing: Creating mockups or scaled models to gather feedback from users with varied accessibility needs before finalizing the design.
4. Construction Documentation
- Ensuring that detailed specifications are provided, including materials for tactile paths, slope gradients for ramps (e.g., 1:12), and accessible restroom amenities like grab bars and sensor taps.
5. Post-Construction Evaluation
- User Walkthroughs: Conducting real-world testing with individuals who have disabilities to gauge the effectiveness of the design.
- Feedback Incorporation: Actively recording and addressing usability issues that occur during testing.
- Accessibility Audit Checklist: Performing a formal assessment aligned with established guidelines to ensure that the project meets all criteria for accessibility.
These structured approaches ensure that the final outcomes not only comply with local regulations but also genuinely improve accessibility and usability for everyone.

• Needs Assessment: Consult with stakeholders, including persons with disabilities and elderly users.
• Site Analysis: Understand topography, existing barriers, and local climate.
• Regulatory Review: Ensure familiarity with accessibility codes, NBC, and UD guidelines.
Detailed Explanation
This stage is about laying a strong foundation for the design process. It begins with a 'Needs Assessment,' where designers engage with actual users, especially those with disabilities, to discover their unique requirements. Then, through 'Site Analysis,' they examine the physical location to identify limitations such as slopes or barriers that could hinder accessibility. Lastly, a 'Regulatory Review' ensures that designers know and understand relevant laws and standards that impact accessibility and Universal Design.
Examples & Analogies
Imagine planning a road trip. Before leaving, you consult maps (Needs Assessment), check the road conditions and weather (Site Analysis), and make sure you have the correct directions that follow the speed limits and traffic laws (Regulatory Review). This way, you prepare effectively, ensuring a smoother journey.
