2.2. Handling and Design Limitations

Try these first

1. 1.

   What is the purpose of pre-testing soil before piling?

   Hint

   Think about what conditions affect pile installation.

2. 2.

   What is a common test used for soil investigation?

   Hint

   This test involves driving a sample into the ground to assess soil properties.

3. 3.

   What is a significant limitation of precast concrete piles?

   • They are lightweight
   • They cannot be adjusted on site
   • They are inexpensive

   Hint

   Think about the implications of handling and design.

4. 4.

   True or False: Pre-stressing concrete piles can allow for greater lengths than standard concrete piles.

   • True
   • False

   Hint

   Consider how internal loads affect external pressures on the structure.

5. 5.

   Consider a project needing 25-meter precast piles. Describe the preparation steps to ensure accurate length and integrity during handling.

   Hint

   Think through both the technical and practical aspects of construction.

6. 6.

   A contractor must choose between precast concrete piles and steel piles for a seaside project, consider environmental conditions, length needed, and handling capabilities. Discuss the criteria for decision-making.

   Hint

   Assess both performance metrics and cost implications.
