Worked Solution & Example Answer:The sketch shows the main entrance to a dwelling house - Leaving Cert Construction Studies - Question 2 - 2014
Step 1
threshold and access ramp
Answer
To create an accessible entrance, the following design choices are implemented:
- Door Width: The opening width should be at least 800 mm, ideally 900 mm to 1000 mm to accommodate wheelchair users. Including a glass panel in the door allows users to see if the door is open.
- Ramp Design: The ramp should have a gentle slope, generally 1:20, and a maximum rise of 120 mm. The ideal ramp length should be between 1800 mm and 2000 mm to provide a comfortable incline.
- Slip-resistant Surface: The ramp surface must be slip-resistant to ensure safety in various weather conditions.
- Handrails: Adding handrails on both sides of the ramp can assist individuals in maintaining balance.
Step 2
weather protection
Answer
Weather protection is crucial for accessibility and comfort:
- Canopy Installation: A canopy or awning over the entrance will shield users from rain and harsh sunlight.
- Select Materials: Using weather-resistant materials for the structure will ensure durability and low maintenance.
- Height Considerations: The canopy should provide enough clearance, ideally over 1800 mm from the ground, to accommodate users of different heights.
Step 3
suitable lighting
Answer
Appropriate lighting is essential for safety:
- Combination of Lighting: The design should include both low and high-level lighting to illuminate the entrance effectively. This is crucial during dusk and night times.
- Sensor-activated Lights: Incorporating motion sensors will ensure that lights are engaged when the entrance is in use, providing a safer entry for users.
Step 4
Discuss in detail two reasons why provision for lifetime use should be considered at the design stage of a dwelling.
Answer
-
Inclusivity for All Users: Ensuring lifetime use in design permits the dwelling to adapt to the needs of its occupants over time, allowing for various abilities and age-related changes. This helps to prevent future renovations and maintains ongoing accessibility.
-
Cost-effectiveness: Planning for lifetime use can reduce overall life-cycle costs. It minimizes the need for major structural changes in the future, which may require extensive funds and resources, ensuring the home remains functional and supportive throughout its lifespan.
