Multiple choice question for engineering
1. Unit of dimensions for ballast is__________
b) micro m
d) cu m
Answer: c [Reason:] Track ballast forms the track bed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. This also serves to hold the track in place as the trains roll by. It is typically made of crushed stone, although ballast has sometimes consisted of other, less suitable materials, for example burnt clay. The term “ballast” comes from a nautical term for the stones used to stabilize a ship.
2. Unit of payment in FPS of Explosive for blasting is__________
b) per lb
c) per gm
d) per cu m
Answer: b [Reason:] Drilling and Blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam or road construction. The result of rock blasting is often known as a rock cut.
Drilling and Blasting currently utilizes many different varieties of explosives with different compositions and performance properties. Higher velocity explosives are used for relatively hard rock in order to shatter and break the rock, while low velocity explosives are used in soft rocks to generate more gas pressure and a greater heaving effect. For instance, an early 20th-century blasting manual compared the effects of black powder to that of a wedge, and dynamite to that of a hammer. The most commonly used explosives in mining today are ANFO based blends due to lower cost than dynamite.
3. Unit of payment in MKS of supply paint ready mix is_________
a) per litre
b) per gl
c) per lb
d) per cu m
Answer: a [Reason:] Paint is any liquid, liquefiable, or mastic composition that, after application to a substrate in a thin layer, converts to a solid film. It is most commonly used to protect, color, or provide texture to objects. Paint can be made or purchased in many colors—and in many different types, such as watercolor, synthetic, etc. Paint is typically stored, sold, and applied as a liquid, but most types dry into a solid.
4. Unit of measurement of supply of bare electric wire in FPS is_________
a) per quintal
b) per cu cm
c) per cwt
d) per m
Answer: c [Reason:] The hundredweight (abbreviation: cwt), formerly also known as the centum weight or quintal, is an English, imperial, and US customary unit of weight or mass of various values. Its present value continues to differ between the American and imperial systems. The two values are distinguished in American English as the “short” and “long” hundredweight and British English as the “cental” and the “hundredweight”.
• The short hundredweight or cental of 100 lb (45.359237 kg) is used in the US and Canada.
• The long or imperial hundredweight of 8 stone (112 lb or 50.802345 kg) sees informal use in the imperial system but according to Schedule 1, Part VI of the Weights and Measures Act 1998, is no longer to be used for trade after the Act came into force.
5. Unit of payment in MKS for supply of timber is ________
a) cu m
b) per cu m

A window is an opening in a wall, door, roof or vehicle that allows the passage of light, sound, and air. Modern windows are usually glazed or covered in some other transparent or translucent material, a sash set in a frame in the opening; the sash and frame are also referred to as a window. Many glazed windows may be opened, to allow ventilation, or closed, to exclude inclement weather. Windows often have a latch or similar mechanism to lock the window shut or to hold it open by various amounts.
8. Unit of payment in MKS is of supply of bricks is ______________
b) %cu ft
c) per % nos
d) % r ft
Answer: c [Reason:] In a large industrial brickworks, clay is taken from the quarry, and then carried by conveyor belt or truck/lorry to the main factory, although it may be stockpiled outside before entering the machinery. When the clay enters the preparation plant (Clay Prep) it is crushed, and mixed with water and other additives which may include breeze, a very fine anthracite that aids firing. This process, which is also known as pugmilling, improves the consistency, firing qualities, texture, and colour of the brick. From here, the processed clay can be extruded into a continuous strip and cut with wires, or put into moulds or presses (also referred to as forming) to form the clay into its final shape. After the forming or cutting, the bricks must be dried, either in the open air, in drying sheds, or in special drying kilns. When the bricks have been dried, they must then be fired or ‘burnt’ in a kiln, to give them their final hardness and appearance.

3. The latrine seat with flushing cistern, flushing pipes are, etc., are usually taken as ______ set for estimation.
Answer: b [Reason:] A latrine is a toilet or an even simpler facility which is used as a toilet within a sanitation system. For example, it can be a communal trench in the earth in a camp to be used as emergency sanitation, a hole in the ground (pit latrine), or more advanced designs, including pour-flush systems.
The term “latrine” is still commonly used in emergency sanitation situations, as well as in army camps. Nowadays, the word “toilet” is more commonly used than “latrine”, except for simple systems like “pit latrine” or “trench latrine”.
The use of latrines was a major advance in sanitation over more basic practices such as open defecation, and helped control the spread of many waterborne diseases.
4. According to ISI method of measurement, the order of the sequence is ___________
a) length, breadth, height
b) breadth, height, Length
c) height, Length, breadth
d) width, Length, breadth

5. The area of a sloping surface of a protective embankment of mean height d, side slopes S: 1 and length L is _________
a) d x d x s
b) (d2 x (ds)2)1/2
c) L.D (1 + s2)1/2
d) 2 L.D (1 + s2)1/2
Answer: c [Reason:] An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil, sand, clay, or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes such a dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance.
6. For 100 sq. m cement concrete (1 : 2: 4) 4 cm thick floor, the quantity of cement required, is ________
a) 0.90 m3
b) 0.94 m3
c) 0.98 m3
d) 0.98 m3
Answer: b [Reason:] Volume – area * thickness.
So, 100 *.04 = 4 cubic metre, 10% for uneven surface.
4 * 10% = .04 = 4.4cubic metre.
50% for dry mortar, 4.4 * 50% = 2.2.
= 6.6cubic meter.
Cement = 6.6/(1 + 2 + 4) =.94 cubic meter.
7. The measurement is made for stone work in square metre in case of __________
a) wall facing
b) columns, lintels, copings
d) building work
Answer: a [Reason:] Stone blocks used in masonry can be dressed or rough, though in both examples: corners, door and window jambs, and similar areas are usually dressed. Stone masonry utilizing dressed stones is known as ashlar masonry, whereas masonry using irregularly shaped stones is known as rubble masonry. Both rubble and ashlar masonry can be laid in coursed rows of even height through the careful selection or cutting of stones, but a great deal of stone masonry is uncoursed.
8. A______________ may be included in an estimate to provide for unknown costs which are indicated as likely to occur by experience, but are not identifiable.
Answer: c [Reason:] When using an estimate which has no contingency to set a budget or to set aside funding, a contingency is often added to improve the probability that the budget or funding will be adequate to complete the project. Being unable to complete a project risks public ridicule. See cost contingency for more information. The estimate or budget contingency is not intended to compensate for poor estimate quality, and is not intended to fund design growth, owner changes, or anything else unrelated to delivering the scope as defined in the estimate documentation. Generally more contingency is needed for earlier estimates due to the higher uncertainty of estimate accuracy.
9. For cost estimating, _________serves as an important framework for organized collection project cost data and preparing the cost estimates at different levels.
Answer: d [Reason:] For cost estimating, work breakdown structure (WBS) serves as an important framework for organized collection project cost data and preparing the cost estimates at different levels. It is a technique that involves the hierarchical breakdown of the project into different work elements at successive levels and defines the interrelationships between them.
10. Generally for any construction project, three parties are involved namely owner, design professionals and construction professionals.
Answer: a [Reason:] In some cases the design professional and construction professional are from the same company or they form a team through a joint venture for providing service to the owner in the project. It is the responsibility of each party involved in the project to estimate the costs during various stages of the project. An early estimate helps the owner to decide whether the project is affordable within the available budget, while satisfying the project’s objectives.
11. The total project cost consists of two components namely front cost and indirect cost.
Answer: b [Reason:] The total project cost consists of two components namely direct cost and indirect cost. Direct cost includes cost of materials, equipment and labour associated with each item of work and also includes cost of subcontracted works. Indirect costs are the costs which are not associated with each item of work rather these costs are calculated for the entire construction work and includes overhead costs (both job office or site office overhead and general head office overhead), contingency i.e. cost for any unforeseen work and profit.
12. Abstract estimate is not the third and final stage in a detailed estimate.
Answer: a [Reason:] This is the third and final stage in a detailed estimate. The quantities and rates of each item of work, arrived in the first two stages, are now entered in an abstract form. The total cost of each item of work is now calculated by multiplying the quantities and respective rates.

6. Obsolescence is the annual periodic payments for repayments of the capital amount invested by a party.
Answer: b [Reason:] An annuity is a series of payments made at equal intervals. Examples of annuities are regular deposits to a savings account, monthly home mortgage payments, monthly insurance payments and pension payments. Annuities can be classified by the frequency of payment dates. The payments (deposits) may be made weekly, monthly, quarterly, yearly, or at any other regular interval of time.
An annuity which provides for payments for the remainder of a person’s lifetime is a life annuity.
7. Scrap value is the net annual letting value of a property, which is obtained after deducting the amount of yearly repairs from the gross income.
Answer: b [Reason:] In financial accounting, scrap value is associated with the depreciation of assets used in a business. In this situation, scrap value is defined as the expected or estimated value of the asset at the end of its useful life. Scrap value is also referred to as an asset’s salvage value or residual value.
8. Residential building for officials are used to be planned on the basis of the income which is 10% of their salary.
Answer: b [Reason:] Due to tremendous increase in the cost of construction it is not possible to plan the building on the basis of income from rent as it will be a too small building.

a) per sq m
b) sq cm
c) cu m
Answer: a [Reason:] To ensure your finished oil or acrylic painting to stay looking its best then adding the right varnish in the right way will be a sound investment. Varnish protects the painting from dirt and dust and evens out the painting’s final appearance, making it all equally glossy or matt.
Over the years dirt and dust will stick to the varnish rather than the painting and when the time is right, the varnish itself can be removed and the painting re-varnished to look as good as new.
3. Unit of payment in MKS of beam is _____________
a) per cu m
b) cu m
c) per sq ft
d) per sq m
Answer: a [Reason:] A beam is a structural element that primarily resists loads applied laterally to the beam’s axis. Its mode of deflection is primarily by bending. The loads applied to the beam result in reaction forces at the beam’s support points. The total effect of all the forces acting on the beam is to produce shear forces and bending moments within the beam, that in turn induce internal stresses, strains and deflections of the beam. Beams are characterized by their manner of support, profile (shape of cross-section), length, and their material.
4. Unit of payment in MKS of RCC bars is _____________
a) per q
b) per kg
c) per tonne
d) per cu m
Answer: a [Reason:] A rebar, or reinforcing bar, is a common steel bar, and is commonly used in reinforced concrete and reinforced masonry structures.

5. Unit of measurement in MKS of DPC is ____________
a) per sq m
b) sq m
c) sq cm
d) per cu m
Answer: b [Reason:] Damp proofing is defined by the American Society for Testing and Materials (ASTM) as a material that resists the passage of water with no hydro-static pressure and waterproof as a treatment that resists the passage of water under pressure. Generally damp proofing keeps moisture out of a building where vapor barriers keep interior moisture from getting into walls. Moisture resistance is not necessarily absolute: it is usually defined by a specific test method, limits, and engineering tolerances.

b) per m
c) per cu m
d) per sq m
Answer: d [Reason:] On a door frame, the sill is the portion of the door frame that runs along the bottom and sits directly on the foundation of your floor. It is the cross piece that actually completes the pre-installed door frame. The sill is actually underneath your threshold.
7. Unit of payment in FPS of supply of lime slaked is _________
a) per acre
b) per cwt
c) per gl
d) per maund
Answer: d [Reason:] Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca(OH)2. It is a colourless crystal or white powder and is obtained when calcium oxide (called lime or quicklime) is mixed, or slaked with water. It has many names including hydrated lime, caustic lime, builders’ lime, slack lime, cal, or pickling lime. Calcium hydroxide is used in many applications, including food preparation. Limewater is the common name for a saturated solution of calcium hydroxide.
8. What is the actual size of standard modular brick-tile?
Answer: b [Reason:] For India, a brick of standard size 190 mm x 90 mm x 90 mm is recommended by the BIS. With mortar thickness, the size of such a brick becomes 200 mm x 100 mm x 100 mm and it is known as the nominal size of the modular brick. Thus the nominal size of brick includes the mortar thickness.
It is found that the weight of 1 cum of brick earth is about 18 KN. Hence the average weight of a brick will be about 30 to 35 N.
9. Actual thickness of wall with 2.5 brick is __________
Answer: c [Reason:] A two-by-four wall stud is 3 ½ inches wide, and an interior wall typically has ½-inch drywall installed on both sides, bringing the wall thickness to 4 ½ inches. Walls that contain plumbing, such as walls behind sinks, however, should be thicker than standard walls. Two-by-six wall studs are 5 ½ inches wide and they provide a larger stud space for running drainpipes, air ducts or other mechanical elements. With the addition of drywall on both sides, a two-by-six wall is 6 ½ inches wide.
