Worked Solution & Example Answer:The main entrance to a dwelling house is designed to facilitate ease of access for everyone - Leaving Cert Construction Studies - Question 1 - 2015
Step 1
To a scale of 1:10, draw a vertical section through the centre of the door.
Answer
To begin, establish the scale of 1:10 on your drawing. Start by depicting the vertical section through the center of the door frame. Represent the door frame as 150 mm x 70 mm. Then, draw the wall with the following details:
- Outer Leaf: Draw the 100 mm concrete block outer leaf on the left.
- Inner Leaf: The inner leaf is a 200 mm timber frame, represented to the right of the outer leaf, framing the cavity.
- Cavity: Indicate a 60 mm insulated cavity between the outer and inner leaves.
- Threshold: Below the door, show the threshold, ensuring it connects with the insulated solid concrete floor which has a 20 mm quarry tile finish.
- Floor Detail: From 500 mm below the finished floor, indicate the layers leading to the threshold and include the floor level clearly.
- Above Door Frame: Ascend to a level that is 300 mm above the top of the door frame, showing any relevant details such as headers or lintels as per best practices. Ensure that dimensions and material indications are clear.
Step 2
On your drawing, show clearly the design detailing that ensures ease of access for all persons.
Answer
Incorporate accessibility features in your drawing to enhance ease of access. Consider the following details:
- Threshold Design: Ensure the threshold is flush with the floor for wheelchair accessibility.
- Dorr Width: Specify a door width of at least 1 meter to accommodate mobility aids.
- Lever Handles: Use lever-style door handles that are easy to operate without requiring grip strength.
- Visual Indicators: Add visual indicators such as braille on door signage for visually impaired persons.
- Clear Space: Ensure there is ample clear space around the door for easy approaching and maneuvering. Mark spaces free of obstructions on both sides of the door to enhance accessibility.
