Worked Solution & Example Answer:The shaded portion of the map shows a site A for a house - Leaving Cert Construction Studies - Question 4 - 2015
Step 1
the entrance to the site at the roadway
Answer
The entrance should be situated on a straight section of the roadway to ensure safety. An unobstructed view of both directions is critical for safe entry and exit. Ideally, the entrance is placed at a minimum distance of 12 meters from the edge of the roadway to facilitate vehicle access and avoid congestion.
Step 2
the driveway to the house from the entrance
Answer
The driveway should ideally follow the natural contours of the land to minimize grading and environmental impact. It should be designed to avoid sharp turns that could reduce visibility. A gentle curve is recommended to encourage safe speeds and enhance the aesthetic of the landscape while allowing easy access to the house.
Step 3
the septic tank and percolation area
Answer
The septic tank should be located at least 7 meters from the house to comply with building regulations. It is critical to situate it at an appropriate distance from the percolation area (10 meters). This ensures optimal waste processing while protecting the environmental quality of the surrounding land.
Step 4
Recommend two suitable types of tree and show on your sketch where you would plant the trees on the site.
Answer
Two suitable types of trees could be:
- Silver Birch (Mountain Ash) - Positioned near the percolation area to absorb excess water.
- Hazel, which can be planted around the entrance to enhance aesthetics and provide privacy.
These trees are native and blend well with the local ecology.
Step 5
Discuss two advantages of planting the recommended trees on the site.
Answer
- Environmental Benefits: Trees play a critical role in absorbing carbon dioxide and releasing oxygen, contributing to improved air quality. They also support local wildlife by providing habitat.
- Aesthetic and Practical Benefits: The trees create visual appeal, enhance the landscape, and provide shade, which can help reduce energy costs in the summer by cooling the house.
