Civil Engineering Interview Questions and Answers List

1) What are the responsibilities of a construction manager?

The responsibilities of a construction manager are

• Cost Estimates
• Pre-purchase of selected materials
• Selection of bidders for bidding phase
• Analysis of proposals
• Construction contract negotiations
• Construction Scheduling and Monitoring
• Cost control of construction
• Construction supervision

2) List out the potential risk factors for workers on the construction site?

Potential risk factors for worker on the construction site

• Falls from heights
• Scaffold and Trench collapse
• Electric shock and arc blast
• Repetitive motion injuries
• Not using personal protective equipment correctly

3) What is OSHA compliance?

OSHA stands for Occupational Safety and Health Act; its motive is to fulfill the health and safety requirement of employees and workers. It is a standard for health and safety that is followed by every industrial segment and corporate offices throughout U.S.A.

4. Define What is the difference between routing maintenance and major maintenance in school facilities?

  • The routine maintenance is the minor and consistent repairs that are engaged in the school premises. Examples could include painting, replacement of fixtures, louver blades, furniture repairs, and patching cracks in the school buildings.
  • The major maintenance could also be a total rehabilitation of the school, either school buildings or any other project within the school community. It could be total restructuring of the lighting system in the school or sanitary system.

5. How are freeway bridges built?
After calculating the anticipated traffic for the bridge, cement/reinforced- with- rebar stanchions are spaced over the freeway to accommodate the bridge. An ‘off-ramp’ from the freeway to the bridge is constructed, as is an ‘on-ramp’ to the subsequent road. Cement/rebar slabs are built and lifted with cranes to form the platform, and voila! Drive carefully.
Although the bridge deck/roadway is almost always a concrete slab, the structure that holds up the bridge deck can be reinforced concrete, structural steel, or a combination of steel and concrete.

6. What is the difference between absorption & adsorption and sorption?

  • Absorption generally refers to two phenomena, which are largely unrelated. In one case, it refers to when atoms, molecules, or ions enter some bulk phase – gas, liquid or solid material. For instance, a sponge absorbs water when it is dry.
  • Absorption also refers to the process by which the energy of a photon is taken up by another entity, for example, by an atom whose valence electrons make transition between two electronic energy levels. The photon is destroyed in the process. The absorbed energy may be re-emitted as radiant energy or transformed into heat energy. The absorption of light during wave propagation is often called attenuation. The tools of spectroscopy in chemistry are based on the absorption of photons by atoms and molecules.
  • Adsorption is similar, but refers to a surface rather than a volume: adsorption is a process that occurs when a gas or liquid solute accumulates on the surface of a solid or, more rarely, a liquid (adsorbent), forming a molecular or atomic film (the adsorb-ate). It is different from absorption, in which a substance diffuses into a liquid or solid to form a solution.

6) List out some of the software used in the construction sector to estimate cost and monitoring expenses?

• Tally System
• Sage
• Maxwell System
• Premier construction software
• eTakeoff
• Construction partner, etc.

7) What is reinforced concrete?

Reinforced concrete have steels bars or mesh in them, which gives extra strength to the construction.

8) What are the different types of foundation?

Three main types of foundation are

• Basement: In this a basement is prepared first on top of it building is constructed
• Crawl space: A crawl space is a raised foundation, it is built above the ground, just allowing enough space to crawl underneath
• Slab: In this foundation, concrete is directly poured into the pit made in the ground.

9. Define What are the uses of alloys in daily life and how are alloys made?

  • Alloying is not always done to produce a ‘superior’ material, but to produce materials having a desired requirement in the industry or elsewhere. A classic case is of lead solder (containing lead & tin), in which the melting point of the constituent elements are lowered, not necessarily a desirable property.
  • Alloying can be carried out using hot press method (a sheet of material is sandwiched with alloying material), rolling the heated base metal in a drum full of alloying metal powder, using hot spraying, galvanizing (dipping the base in a molten solution of alloying material) etc. Sometimes the alloying material is added in small proportions to the molten base metal (e.g., in production of different types of steel).

10. What is the worlds largest concrete dam?
The Grand Coulee Dam is said to be the largest concrete dam. Currently the world’s largest concrete dam is the Itaipu Dam, an accomplishment of two neighboring countries, Brazil and paraguay in South America.
Though it is not finished yet, the Three Gorges (or Sandapong) Dam on the Yangtze River in China will take over as the largest upon its completion, which is slated for 2009.

11. What is braced excavation all about?
Excavations are braced to prevent the cave-in of surrounding unstable soil.

12. What is the meaning of soil reinforcement?
Soil reinforcement is the act of improving soil strength to enable it support or carry more load.
Two common examples are:

  1. Mixing a soil amendment such as lime into weak clayey soil and re-compacting to improve soil-bearing capacity (often done under the road base in highway construction)
  2. Installing plastic or composite webbing layers (called geo-grid material) alternating with compacted soil to produce a stronger sloped soil structure (often done on steep roadway embankments to improve strength and stability)

13. Define What is aggregate?
Aggregate is the component of a composite material used to resist compressive stress.

14. What year was the keystone power plant in Indiana County constructed?
1967 began commercial operation on unit 1.

15. Define What is the force exerted by the Tacoma narrows bridge?
The force exerted to the Tacoma narrows bridge was initially the wind resistance. The wind resistance caused the whole bridge to act as a system with forced vibration with damping.

16) Explain what is alternate bid?

Alternate bid is the amount stated in the bid to be deducted or added from the base bid amount. Alternate bid is proposed when there is a use of alternate materials or methods of construction.

17) Explain what is change order request?

Change order request is a written document issued or given by the owner, requesting an adjustment to the contract sum or an extension of the contract time. Usually, it is issued by the architect or owners representative.

18) What does a construction cost covers and what does not?

A construction cost covers material, labor, equipment and services, contractor’s overhead and profit and other direct construction costs. While, it does not cover compensation paid to the architect, consultant or engineers, cost of the land and other cost that is owner’s responsibility.

19) Explain what is Critical Path Method (C.P.M)?

Critical Path Method is strategy and method of representing the respective tasks and activities involved in the construction through a symbolic diagram.

20. How do we calculate absolute pressure?
Absolute is equal to gauge pressure plus atmospheric.

21. What is Gravity flow?
Gravity flow is fluid flowing due to the forces of gravity alone and not to an applied pressure head. In the Bernoulli equation, the pressure term is omitted, and the height and velocity terms are the only ones included.

22. What is horizon or horizontal mining?

  • Horizon or horizontal mining can be applied to extraction of material from seams of any stratified mineral such as limestone or ironstone, but it is more usually associated with coal – particularly where there are several seams that are inclined or folded and/or faulted.
  • Horizon mining involves long level roadways (horizons) being driven from the shafts to the extremity of the area to be mined.
  • The levels of the horizons are chosen to intersect the maximum number of seams the maximum number of times. As the seams are intersected, headings will be driven into the seam so that the desired material may be extracted. This method of mining requires a thorough understanding of the geological structure of the area to be mined so that the level of the horizons can be chosen for optimum results.
  • This method of mining is popular in modern coalmines with seams worked from several horizons. The considerable capital outlay of driving horizons before production can begin is recouped by the advantage of having long straight level roadways of generous dimensions unaffected by the crushing effect of nearby extraction of the mineral.

23) Explain what is structural frames or systems?

Structural frames are a load bearing assembly of beams and columns on a foundation. Normally, the columns and beams are generally fabricated off site and assembled on site.

24) Explain what is zoning permit?

Zoning permit is a document issued by governing urban authority permitting land to be used for a particular purpose.

25) Explain what is the release of lien?

Release of lien is a written document executed by an individual or firm supplying labor, material or professional service on a project, which release his mechanic’s lien against the project property.

26) What is Architect-Prepared Contract?

Architect- Prepared Contract is an agreement prepared in-house by the architect between owner and architect, and often reviewed by an attorney, before its execution. It is a legal contract, and it includes all terms and conditions including adequate legal protection for both the parties.

27) Explain what is 1/8 on the architect ruler denotes?

1/8 on the ruler is infact a scale that converts 1/8 inch on to the drawing to 1 foot. It would represent a drawing with a scale of 1/8”= 1 foot.

28) Explain what is the difference between built area and super built up area?

• Built up area: It includes your carpet area plus area covered by walls, pillars and ducts. It is usually 10% more from the carpet area
• Super built up area: It includes your built up area plus the area that you use as building amenities like passage to lift, stairs and lifts, gym, club, etc.

29. Define What is a kip?
1 kip = 1000 lbs

30. What are some structures that may be subjected to fatigue?
Bridges, hydraulic presses, burners trains
