Worked Solution & Example Answer:The accompanying diagram shows an open-plan living, dining and kitchen space suitable for a person in a wheelchair - Leaving Cert Construction Studies - Question 2 - 2010
Step 1
Using notes and freehand sketches show the design detailing at the entrance door to ensure that rainwater is removed from the threshold area and that the entrance is suitable for a person in a wheelchair.
Answer
To design an entrance suitable for a person in a wheelchair and to manage rainwater effectively, follow these steps:
-
Level Entrance: Ensure the entrance has a minimum turning circle of 1500 mm in diameter to allow sufficient space for maneuvering.
-
Ramp Design: Install a ramp with a maximum slope of 1:20 to facilitate access. The path should lead directly to the door without any obstructions.
-
Drainage Channel: Incorporate a drainage channel fitted beside the threshold to assist in the removal of rainwater, preventing water accumulation at the entrance.
-
Reinforced Threshold: Construct a reinforced concrete threshold with a slope of 15 degrees to guide water away and enhance wheelchair accessibility.
-
Dam-proofing: Utilize dam-proofing measures, such as a trapper bar of at least 15 mm in height, to prevent water ingress.
-
Insulation: Include vertical insulation to the inner leaf of the wall to maintain thermal comfort.
-
Final Touches: Ensure the design features a robust frame, with adequate skirting board heights adjusted for wheelchair accessibility.
Step 2
Select any two areas that need specific consideration to ensure suitability for a person in a wheelchair. For each area selected, using notes and freehand sketches, show the specific design detailing.
Answer
- Dining Area:
-
Use a circular dining table to facilitate ease of movement around the space.
-
Ensure the table height is lower or adjustable for wheelchair users, ideally around 700 mm.
-
Position the table centrally on a pedestal to provide ample leg room.
-
Trolleys should be used for transferring cooking and food-related items, ensuring non-slip floor surfaces at 900-1200 mm above the floor level for easy access.
-
Electrical switches should be positioned at an accessible height and easily reachable from a seated position.
- Kitchen Area:
- The sink and cooking appliances need to be grouped in a triangular layout, ensuring a distance of at least 1800 mm between the cooker and sink for safety.
- Use an accessible workspace along both sides of the cooker, incorporating no-press areas around the sink for safety.
- The kitchen should feature an accessible sink fitted at approximately 800 mm height and preferably with height-adjusted controls.
- Doors in this area should be 800 mm wide to ensure easy passage without requiring additional effort.
