Civil Engineer Interview Questions 7 Civil Engineer Interview Questions and Answers Whether you are preparing to interview a candidate or applying for a job, review our list of top Civil Engineer interview questions and answers. Tweet What made you decide to become a civil engineer? This question allows candidates to explain their reasons for becoming a civil engineer. The answer will be unique to individuals and will give you insight into what inspired them to choose this career path. What to look for in an answer: A genuine answer that reflects a true passion for this career path An unhurried reply that shows that the answer was well thought out Example: "I decided to become a civil engineer because of my father who is a Math teacher. As a child he shared his great love for solving mathematical equations and other types of puzzles with me. He was always asking me to look outside the box to solve each dilemma.
The tensile strength of a material is the value at which the material fails when subjected to a tensile force. Tensile means a force pulling the wood fibers lengthwise, as opposed to a compressive force.
There are a lot of different types and load cases for wood, so there is not one answer to this question.
For example, wood used outside will fail at a lower load than wood inside. Wood is also anisotropic, i. A good reference for material strength data for most species and grades of commercially available wood can be found in the American Institute of Timber Construction handbook. How many Lbs are there in a yard?
A pound Lb is a unit of measurement for weight while a yard is a unit of measurement for distance. If you are referring to common measurements used on a construction site, a yard is a common abbreviation for a cubic yard, which is a unit of measurement of volume.
A cubic yard equals 27 cubic feet. Since dirt weighs about pounds per cubic feet, a cubic yard of dirt weighs about Lbs. Since concrete is heavier PCF , a cubic yard of concrete weighs about Lbs.
What is a projection line? Projection line is the way, in which the earth is shown on a flat piece of PAper. What are moment of inertia and its importance in civil engineering?
The moment of inertia measures the opposition any kind of body will have against a certain momentum along that same axis trying to rotate that body. What is the origin of name Railway Sleepers? When sleepers were added below the railway, lines the trains ran more smoothly and people fell asleep on their journeys. Does brick grows bigger every year.
Usually bricks do not grow, but since stuff gets all over, it looks like it grows. How did street originate in the plumbing term street ell? A street ell may have gotten its name because it describes a 90 fitting PArticularly useful in tight, street ditches. When installing water pipes under a street, or from a water service, again under the street, into a home or business, this street ell allows one to change pipe direction with one less fitting, and in less sPAce, than with a standard ell.
What is the absolute pressure scale?
Absolute pressure is calculated from a vacuum 0 PSI and atmospheric pressure is What is the difference between QA and QC? Many people and organizations are confused about the difference between quality assurance QA , quality control QC , and testing. They are closely related, but they are different concepts. Since all three are necessary to manage the risks of developing and maintaining software, it is important for software managers to understand the differences.
Note that the process of executing a system includes test planning prior to the execution of the test cases. How did the Romans get water up hills using aqua ducts? Technically, the Romans were not able to get water to move uphill in a general sense. All aqueducts move water from an elevated source spring-fed streams in the mountains to end-users at a lower elevation.
The water flows almost entirely downhill from the source to the end user. If the water needed to cross a valley, the Romans would build an arched structure with an elevated channel to cross the valley, but even this channel would have a vary slight downhill gradient that allowed water to flow towards the end user.
If a large hill was in their way, the Romans would either divert the channel around the hill, dig a trench through the hill, or dig a tunnel through the hill, all while maintaining a fairly constant, slight downhill gradient towards the end user. The only exception to the rule of a generally constant downhill slope to the water channel is that specific tunnel segments, the Romans could build the tunnel as an inverted siphon mentioned above to cross a depression or valley and raise the water level on the downhill side almost to the level of the uphill side.
To do this requires a well-sealed tunnel strong enough to withstand the increased water pressure within the siphon. Note, however, that except for gaining a little bit of elevation if you slow down fast-moving water, you normally cannot get water to flow out of the outlet at a higher elevation than the inlet. So technically, even the Romans were not able to get water to flow up a hill.
Will Water damage concrete? As far as only concrete is concerned i. The defects that water seePAge induces in concrete are as follows: a induces capillary formation due to the detiorating characteristics of water b With this capillaries the concrete starts sPAlling out; i. It also reduces the pH of the concrete when in salty water or when exposed to marshy areas.
How do you determine Specific gravity of cement? Cement is usually downloadd as a powdery substance that is mixed with sand, aggregate, gravel, and water to form concrete. Since the cement itself is usually a powder, it is hard to measure a standard value for its specific gravity.
In addition, since cement is usually not used by itself, knowing its specific gravity is not Particularly useful. A more useful question is What is the typical density of concrete?
A rule of thumb answer is that normal cured concrete has a density of about pounds per cubic foot. This includes the weight of the cement, sand, aggregate, and that PArt of the water that chemically binds with the cement to form the concrete. In this foundation, concrete is directly poured into the pit made in the ground. Hybrid Foundation is usually used for high rise building, it contains both soil supported mat and piles.
This type of foundation is helpful in reducing the amount of the settlement. A floating concrete foundation is a type of mat foundation that consists of the hollow mat formed by a grid of thick reinforced concrete walls between two thick reinforced concrete slabs.
Flashing is an extended construction that is done to seal and protects joints in a building from water penetration. Flashing is installed at the intersecting roofs, walls and parapets. 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. 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. Critical Path Method is strategy and method of representing the respective tasks and activities involved in the construction through a symbolic diagram.
It is a bond between the owner and the main contractor. It is a payment done by owner to the contractor; it is a difference between the completed work and material stored and a pre-determined schedule of values or unit costs.
Structural frames are a load bearing assembly of beams and columns on a foundation. This simply translate that aluminum is 3 times flexible than steel. On a per pound basis, steel pipe is stronger in bending and is less likely to buckle in axial compression. The input power, that is, the power required to operate the pump should be stated in Hp horsepower on the pump's nameplate.
It can also be calculated by the 3-phase power equation:. The output power, which really is not technically power, but rated in Gpm gallons per minute , or caPAcity should also be on the nameplate.
If you have the make, model, and not necessarily needed the serial number also on the nameplate you could call the manufacturer's customer service dept.
It is now big deal to them, they will be happy to answer your questions. In sailing, the ropes used to move the sails around so the boat will move in the right direction when the wind blows.
Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure. 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. Some people call it an air pocket in the concrete or a void.
It is the exposed course aggregates on surface of concrete without covered by mortar or surrounding the aggregate particles.
Purpose of the gap in the road is to allow the road to exPAnd and contract with temperature changes without causing damage or deformation to the road. The moment of inertia measures the opposition any kind of body will have against a certain momentum along that same axis trying to rotate that body.
Absolute pressure is calculated from a vacuum 0 PSI and atmospheric pressure is When a dam is to be built, a diversion tunnel is usually bored through solid rock next to the dam site to byPAss the dam construction site.
The dam is built while the river flows through the diversion tunnel. If you have water pressure and wish to maintain it, do not cause flow in the line, which will reduce pressure due to friction.
To keep pressure up, reduce friction by increasing the line size or eliminating some other restriction. Soil pressure increases with depth due to the overburden or self-weight of the soil and due to loads imposed upon the soil.
As depth increases, there will be a linear increase in the soil pressure. Get daily job alert, placement paper and GK updates every day on your email.
