Worked Solution & Example Answer:The main entrance to a dwelling house, as shown in the accompanying sketch, provides access for a person in a wheelchair - Leaving Cert Construction Studies - Question 1 - 2006
Step 1
To a scale of 1:5, draw a vertical section through the external wall and door, showing clearly the threshold and the door.
Answer
- Begin by sketching the external wall at a scale of 1:5. Include details such as the materials used, the insulated cavity, and the solid wooden door.
- Clearly depict the threshold, ensuring all components are shown accurately, including the concrete ground floor and the 20mm quarry tile finish above.
- Include a detailed representation of the foundation components, starting from the concrete cill to the finished floor level.
- Ensure the final drawing is neat and annotations for dimensions and materials are included for clarity.
Step 2
Indicate on the drawing the specific design detailing that ensures that rainwater is removed from the threshold area and does not penetrate to the inner surfaces surrounding the door.
Answer
- Draw a proprietary threshold that includes a drainage channel designed to direct rainwater away from the door area to a suitable discharge location.
- Incorporate a damp proof course (DPC) behind the threshold, ensuring it is positioned correctly to prevent water ingress.
- Indicate the slope of the concrete cill at 15° to facilitate proper water runoff.
- Ensure that the surface is sloped appropriately towards the drainage channel to promote effective water discharge.
