Quantity Surveyor and Site Engineer Interview Questions and Answers

Typically, 8-10 kg of binding wire is required per ton of steel for effective binding in construction.

• Binding wire is essential for tying rebar in concrete structures.

• The standard requirement is about 8-10 kg of binding wire per ton of steel.

• For example, if you have 5 tons of steel, you would need approximately 40-50 kg of binding wire.

• The amount can vary based on the complexity of the structure and the tying method used.

Lapping, joggle, and overlap are engineering terms related to joining materials and ensuring structural integrity.

• Lapping: A method where two materials overlap to increase strength; commonly used in welding and metal fabrication.

• Joggle: A technique where one material is bent to fit another, often used in sheet metal work to create a snug fit.

• Overlap: Refers to the extent to which two materials cover each other; important in roofing and flooring applications.

Additional reinforcement in beams enhances structural integrity and load-bearing capacity, preventing failure under stress.

• Provides extra strength to resist tensile forces, especially in areas with high bending moments.

• Commonly located at the bottom of beams where tensile stresses are greatest.

• Used in regions of support and mid-span to counteract shear forces.

• Example: In a simply supported beam, additional reinforcement is often placed near the supports.

• In continuous beams, e...read more

The formula for shear force is the derivative of the bending moment equation.

• Shear force is the force that acts parallel to a surface, causing it to slide or shear.

• The formula for shear force can be derived from the bending moment equation.

• The shear force at any point on a beam can be calculated by taking the derivative of the bending moment equation with respect to the distance along the beam.

• The formula for shear force can vary depending on the type of loading and support c...read more

The volume of a cylinder can be calculated using the formula V = πr^2h.

• The formula for the volume of a cylinder is V = πr^2h, where V is the volume, r is the radius of the base, and h is the height.

• To calculate the volume, square the radius, multiply it by π, and then multiply the result by the height.

• For example, if the radius is 3 units and the height is 5 units, the volume of the cylinder would be V = π(3^2)(5) = 45π cubic units.
