Eastman Infrastructure Interview Questions and Answers

Piling works involve the construction of deep foundations to support structures on unstable soil or rock.

• Piling works are used to transfer the load of a structure to a deeper, more stable layer of soil or rock.

• Different types of piles are used, such as driven piles, bored piles, and auger cast piles.

• Piling works are commonly used in the construction of bridges, high-rise buildings, and waterfront structures.

• Piles can b...read more

There are typically three types of polymer tests conducted before drilling pile.

• Polymer viscosity test

• Polymer filtration test

• Polymer compatibility test

Viscosity is the measure of a fluid's resistance to flow. The viscosity of a polymer depends on its molecular weight and temperature.

• Viscosity is a property of fluids that determines their flow behavior.

• It is a measure of a fluid's resistance to flow.

• Viscosity is influenced by factors like temperature and molecular weight.

• Polymers can have different viscosities depending on their molecular weight and temperature.

• Higher...read more

The number of pile load tests required depends on various factors such as project specifications, soil conditions, and design requirements.

• The number of pile load tests is determined based on the project specifications and design requirements.

• The soil conditions at the site play a crucial role in determining the number of pile load tests.

• Different types of pile load tests, such as static load tests and dynamic load tes...read more

The depth of bore pile is decided based on soil investigation report and load-bearing capacity of soil.

• Soil investigation report helps to determine the soil type and its load-bearing capacity.

• The load-bearing capacity of soil is determined by conducting Standard Penetration Test (SPT) or Cone Penetration Test (CPT).

• The depth of bore pile is decided based on the load-bearing capacity of soil and the design load of the s...read more
