Worked Solution & Example Answer:The main external doorway of a dwelling house is designed to facilitate access for everyone, including a person with reduced mobility, as shown in the sketch - Leaving Cert Construction Studies - Question 1 - 2011
Step 1
a) Draw a vertical section through the centre of the door
Answer
- Begin by setting up your drawing to scale 1:10.
- Draw the vertical section of the door starting from 500 mm below the finished floor level maintaining appropriate dimensions.
- Include the door construction, ensuring to show the 12 mm thick vertical sheeting.
- Illustrate the doorframe using the specified dimensions of 150 mm x 70 mm.
- Represent the external wall (350 mm) around the doorframe and include the insulated cavity detail.
- Continue the drawing to a height of 300 mm above the lintels, making sure to draw the concrete lintels clearly.
- Ensure the overall section clearly reflects all specified details and dimensions.
Step 2
b) Show the design detailing that ensures rainwater removal
Answer
- On the same drawing, indicate the design features that facilitate effective rainwater removal from the threshold area.
- Illustrate an overhanging roof or canopy above the door to prevent direct rain contact.
- Show a sloped threshold or a drip edge to direct water away from the doorway.
- Include appropriate materials that can withstand moisture and prevent water accumulation.
- Optionally, depict drainage provisions or channels to facilitate further water diversion away from the threshold.
