Study Notes
Foundation Design Basis
- Primary basis for foundation design is the assessment of soil conditions.
- Understanding soil bearing capacity is essential for stable structures.
Factors Affecting Construction Activities
- Specific factors affecting construction, such as weather conditions and site conditions, are mentioned, while unlisted factors may include political or social influences.
Determining Underground Soil Conditions
- Most suitable method for determining underground soil conditions is the use of borehole drilling.
Wash Boring Method
- Described as a technique that utilizes water to remove soil, allowing for easier collection of soil samples and assessment of subsurface conditions.
Site Investigation Importance
- Directly related to the design and planning of construction projects due to its role in identifying potential risks and soil characteristics.
Depth of Boring or Test Pits
- Depth relates to the extent of soil investigation needed to ensure the adequacy of the foundation design.
Method for Resisting Materials
- Most rapid method for penetrating highly resistant materials such as rocks, clay, or sand involves rotary drilling techniques.
Purpose of a Penetrometer
- Used to measure the resistance of soil to penetration, providing insight into soil strength and characteristics.
Purpose of Batter Boards
- Essential in the layout and staking process for defining building corners and elevation levels.
Purpose of Plastic Water Hose
- Utilized to establish levels for laying out the foundation and ensuring accuracy in placement.
Purpose of Level Transit
- Instrument used to measure horizontal and vertical angles, crucial in achieving precise layout and leveling during construction.
Purpose of String or Chord
- Serves as a reference line in the layout process to ensure straight walls and proper distances between structures.
