    Study Notes

    Site Investigation Purpose

    • Ensures understanding of ground conditions prior to building design and construction
    • Identifies potential risks and informs safe construction practices

    MasterFormat Divisions

    • Division including Site Remediation and Water Remediation: Division 02
    • Division including Earth Moving and Special Foundations: Division 31

    Desk Study Purpose

    • Conducted to gather preliminary data about a site
    • Reviews existing information to guide further investigations

    Subsurface Investigation Purpose (Division 02)

    • Aims to assess soil and groundwater conditions
    • Supports safe and economical design based on subsurface conditions

    Division 31: Earthwork Focus

    • Primarily deals with ground preparation for construction projects
    • Includes excavation, grading, and other earth-moving activities

    Soil Investigation Purpose

    • Identifies soil properties to ensure structural integrity and safety
    • Provides essential data for appropriate foundation design

    Factors Affecting Depth of Soil Investigation

    • Type of structure planned (e.g., high-rise vs. single family)
    • Site-specific conditions such as soil type and groundwater presence

    Trial Pits Use Case

    • Generally used in cohesive or soft ground for easy excavation
    • Allows direct observation and sampling of soil layers

    Suitable Boring Method for Depths Over 3 Meters

    • Rotary drilling method is preferred for deeper soil investigation
    • Ensures accurate sampling and data collection at significant depths

    Wash Boring Method Description

    • Involves forcing water through drilling tools to clear debris
    • Useful for collecting soil samples while maintaining borehole stability

    Determining Soil Investigation Method

    • Based on site-specific conditions, investigation goals, and budget
    • Considerations include depth, soil type, and required data accuracy

    Use of Cylindrical Augers and Shells

    • Employed when sampling cohesive soils or unstable formations
    • Effective for collecting continuous soil samples

    Purpose of Establishing Subsoil Characteristics

    • To identify potential geotechnical issues that could impact construction
    • Important for regulating factors like drainage, load-bearing capacity, and contamination

    Hand or Mechanical Auger Use Case

    • Suitable for shallow investigations where quick soil sampling is needed
    • Efficient for preliminary assessments or areas with limited access
