THDC Senior Civil Engineer Interview Questions, Process, and Tips

Site plans are detailed drawings that show the layout of a construction site and its surrounding area.

• Site plans provide a visual representation of the proposed development on a piece of land.

• They show the location of buildings, roads, utilities, landscaping, and other features.

• Site plans help ensure that the development complies with zoning regulations and building codes.

• They are used by architects, engineers, and con...read more

Types of foundations include shallow, deep, and special foundations.

• Shallow foundations: spread footings, mat foundations

• Deep foundations: piles, drilled shafts

• Special foundations: caissons, cofferdams

Poisson ratio is the ratio of lateral strain to longitudinal strain in a material subjected to stress.

• It is a measure of the deformation of a material under stress.

• It is denoted by the symbol 'ν' (nu).

• It is a dimensionless quantity.

• It is used in the calculation of the elastic modulus of a material.

• For most materials, the Poisson ratio is between 0 and 0.5.

• Rubber has a Poisson ratio close to 0.5, while cork has a Poisso

Shear and bending moment diagrams show the variation of internal forces along a beam.

• Shear diagram shows the variation of shear force along the length of the beam.

• Bending moment diagram shows the variation of bending moment along the length of the beam.

• Shear force changes sign at point of concentrated load or reaction.

• Bending moment is zero at points of concentrated load or reaction.

Yes, DPC (damp proof course) is required in boundary walls to prevent rising damp.

• DPC is necessary to prevent moisture from rising up through the walls.

• It helps in protecting the structure from dampness and water penetration.

• Common materials used for DPC include bitumen, plastic sheets, and chemical compounds.

• Proper installation of DPC is essential to ensure its effectiveness in preventing dampness.
