The allowable presumptive load-bearing pressure of loose, fine sand for a foundation is typically around 2,000 psf. This value is derived from geotechnical engineering guidelines that assess the structural properties of different soil types under load. Loose, fine sand has relatively low cohesion and is more susceptible to shifting under pressure, which is why the allowable load-bearing capacity is not as high as denser soil types or those with greater cohesion.

Understanding load-bearing pressures is crucial for construction supervisors as it informs decisions about foundation design and materials used. Exceeding the allowable load can lead to structural failure, making it essential to adhere to these standard values during the planning and construction process.
