Q1.Why did you choose civil engineering?

A civil engineer can be involved in a range of projects. If you work for a civil engineering company that accepts diverse clients, you will have the opportunity to work on different projects including building roadways, railways, bridges, commercial buildings, residential complexes, and others.

Q2. How do you measure the volume of concrete? with Example?

Calculating the volume for concrete requires using three dimensions: length times width (which is area) times the height (thickness) or L x W x H. If you are using feet as your standard unit of measurement, this formula will give you the volume of concrete in cubic feet.

1. 10 x 10 = 100 square feet.
2. 4 ÷ 12 = .33.
3. 100 x .33 = 33 cubic feet.
4. 33 x .037 = 1.22 cubic yards

Q3. What are the responsibilities of a construction manager?

Overseeing and directing construction projects from conception to completion. Reviewing the project in-depth to schedule deliverables and estimate costs. Overseeing all onsite and offsite constructions to monitor compliance with building and safety regulations.

Q4.List out the potential risk factors for workers on the construction site?

Site risks can include working at height, moving machinery (vehicles, cranes, etc.) and materials, power tools and electrical equipment, hazardous substances, plus the effects of excessive noise, dust, and vibration.

Q5. What is the water-cement ratio?

Water Cement Ratio means the ratio between the weight of water to the weight of cement used in the concrete mix.

Normally water cement ratio falls under 0.4 to 0.6 as per IS Code 10262 (2009) for nominal mix (M10, M15 …. M25)

We all know that the water-cement ratio will directly affect the strength of concrete. Either it increases the strength if used in the correct proportion or decreases it.

But have you ever thought about it why we are using water if it has so much difficulty?

Q6.How are bridges used by automobiles constructed?

How Are Bridges Built? When bridges requiring piers are built over a body of water, foundations are made by sinking caissons into the riverbed and filling them with concrete. Next, the anchorages are built on both ends, usually of reinforced concrete with embedded steel eyebars to which the cables will be fastened.

Q7.How do check the level on the construction site?

1. Inspect your builder’s level. …
2. Get a 100+ foot tape measure and two measurement rods. …
3. Set up the builder’s level on a tripod.
4. Locate the thumbscrews and turn them to adjust the vials to the center.
5. Measure 100 feet from the builder’s level in opposite directions.

Q8. What is reinforced concrete?

reinforced concrete, concrete in which steel is embedded in such a manner that the two materials act together in resisting forces. The reinforcing steel—rods, bars, or mesh—absorbs the tensile, shear, and sometimes compressive stresses in a concrete structure.

Q9.What is the size of a concrete cube?

What is the Concrete Cube Test? Like the cylinder brake test, the concrete cube test is performed to determine the compressive strength of a concrete element. The cubes used for this test have a dimension of 150 x 150 x 150 mm as long as the largest aggregate does not exceed 20 mm.
Q10. Explain what is Hybrid Foundation?
A hybrid foundation system defined as the combination of shallow and deep foundations has been developed as an alternative to large diameter suction piles, to tackle ever-increasing flowline walking loads in deepwater subsea field developments.
Q11. Mention different types of roof systems?
• Type #1: Asphalt roof shingles. …
• Type #2: Rubber membrane roofing systems. …
• Type #3: Slate roofing systems. …
• Type #4: Clay tile roofing systems. …
• Type #5: Metal roofing systems. …
• Type #6: Composite & rubber roofing systems. …
• Type #7: Solar tile roofing systems.

Q13.What is aggregate?

An aggregate is a collection of people who happen to be at the same place at the same time but who have no other connection to one another. Example: The people gathered in a restaurant on a particular evening is an example of an aggregate, not a group.
Q14.What is the meaning of soil reinforcement?
Reinforced soil or mechanically stabilized soil consists of soil that is strengthened by tensile elements such as metal strips, geotextiles, or geogrids. The development of polymeric materials in the form of geosynthetics has brought major changes in geotechnical engineering.
Q15. What is the mix ratio for the M20 Grade of concrete?
M20 concrete mix ratio:- M20 concrete mix ratio is 1:1.5:3, made of a mixture of cement, sand, and aggregate in which one part is cement, 1.5 parts are sand and 3 parts are aggregate or stone.
Q16.What is the difference between engineering stress and true stress?
True stress is the applied load divided by the actual cross-sectional area (the changing area with time) of material. Engineering stress is the applied load divided by the original cross-sectional area of a material.
Q17. What is the Unit weight of 12 mm Steel Bars?0.89 kg/meters

Q18. What is an Architect-Prepared Contract?

Architecture Contracts are the joint agreements between development partners and sponsors on the deliverables, quality, and fitness-for-purpose of an architecture. Successful implementation of these agreements will be delivered through effective architecture governance (see Architecture Governance).
Q19. Are you familiar with computer-aided design (CAD) software?
Computer-Aided Design (CAD) is the use of an application to help create or optimize a design. Therefore, CAD software allows engineers, architects, designers, and others to create precision drawings or technical illustrations in 2D or 3D.
Q20.What is the Density of Steel?7850 kg/m³
