Civil Billing Engineer Interview Questions and Answers

Reinforcement is provided to concrete to enhance its strength and durability.

• Reinforcement helps to resist tensile forces in concrete, which is weak in tension.

• It improves the structural integrity and load-bearing capacity of concrete elements.

• Reinforcement prevents cracking and enhances the ductility of concrete.

• It provides resistance against shrinkage and thermal expansion.

• Examples of reinforcement include steel bars, mesh, and fibers.

IS Code 1200 Part 1 is used for quantity survey for earth work.

• IS Code 1200 Part 1 provides guidelines for measurement and billing of earthwork in civil engineering projects.

• It includes methods for calculating quantities of excavation, backfilling, and earthwork in embankments.

• The code also covers specifications for the preparation of bills of quantities for earthwork.

• Engineers and contractors refer to IS Code 1200 Part 1 to ensure accurate quantity surveying for earthwork.

To prepare a bill and ask more questions from measurement, one must accurately measure quantities, apply appropriate rates, and ensure all work is accounted for.

• Accurately measure quantities of work done

• Apply appropriate rates for each item of work

• Ensure all work done is accounted for in the bill

• Ask detailed questions about the measurements to clarify any discrepancies or uncertainties

Design mix is a specific combination of materials to achieve the desired properties in a concrete mix.

• Design mix is a proportionate mixture of cement, sand, aggregates, and water to achieve the desired strength and workability of concrete.

• It is designed based on the specific requirements of a project, such as strength, durability, and workability.

• Design mix is determined through laboratory testing and calculations to ensure the concrete meets the desired specifications.

• For ex...read more

M20 mix design ratio is a commonly used concrete mix design with a ratio of 1:1.5:3 (cement:sand:aggregate).

• M20 mix design ratio is 1:1.5:3, which means 1 part cement, 1.5 parts sand, and 3 parts aggregate.

• This mix is commonly used for residential construction projects.

• The strength of M20 concrete is typically around 20 MPa (megapascals) after 28 days of curing.

There are different types of cement used in construction, each with specific properties and applications.

• There are various types of cement such as Ordinary Portland Cement (OPC), Portland Pozzolana Cement (PPC), Rapid Hardening Cement, etc.

• OPC is commonly used for general construction purposes, while PPC is known for its durability and resistance to chemicals.

• Rapid Hardening Cement is used in projects where quick setting and early strength development are required.

• Each type o...read more

Compression strength is the ability of a material to withstand loads that reduce the size of the material.

• Compression strength is a measure of how much force a material can withstand before it starts to deform or break under compression.

• It is an important property for materials used in construction, such as concrete and steel.

• Compression strength is typically expressed in units of force per unit area, such as pounds per square inch (psi) or megapascals (MPa).
