Sample WBCHSE HS Vocational Construction Practice Questions

Try these sample questions to test your WBCHSE HS Vocational Construction exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What are the standard dimensions of a modular building brick without mortar as per Indian Standards?
A.19 cm x 9 cm x 9 cm
B.20 cm x 10 cm x 10 cm
C.22.5 cm x 11.25 cm x 7.5 cm
D.18 cm x 8 cm x 8 cm
Explanation: According to IS 1077, the standard nominal dimension of a modular brick without mortar is 19 cm x 9 cm x 9 cm. When laid with mortar, the nominal dimension becomes 20 cm x 10 cm x 10 cm. This standard size ensures uniformity and modular coordination in construction.
2What is the minimum initial setting time specified for Ordinary Portland Cement (OPC) according to IS 269?
A.15 minutes
B.30 minutes
C.60 minutes
D.600 minutes
Explanation: The minimum initial setting time for Ordinary Portland Cement (OPC) is 30 minutes as per Indian Standards. This gives construction workers sufficient time to mix, transport, placement, and compact concrete before hydration causes stiffening.
3Which field test apparatus is most commonly used to measure the workability and consistency of fresh concrete?
A.Slump Cone Apparatus
B.Vicat Apparatus
C.Le Chatelier Mould
D.Sieve Shaker
Explanation: The slump cone test apparatus is the standard field tool used to measure concrete workability and consistency (IS 1199). It consists of a metallic frustum of a cone with height 300 mm, bottom diameter 200 mm, and top diameter 100 mm.
4What is the primary function of a Damp Proof Course (DPC) provided at plinth level in a building?
A.To increase structural load-bearing capacity
B.To prevent groundwater moisture from rising into walls by capillary action
C.To provide a decorative horizontal border
D.To bind foundation concrete with brick masonry
Explanation: A Damp Proof Course (DPC) is a continuous layer of water-impermeable material (such as rich cement concrete treated with waterproofing compound or bituminized felt) laid at plinth level. Its main objective is to stop groundwater dampness from creeping up into upper wall structures via capillary action.
5What is a brick cut lengthwise into two equal halves called in brick masonry terminology?
A.King Closer
B.Queen Closer
C.Half Bat
D.Bevilled Closer
Explanation: A Queen Closer is a brick cut longitudinally into two equal halves along its length. It is placed next to the quoin header in alternate courses to overlap vertical joints properly in brick bonding.
6What standard length is most widely used for metric surveying chains in Indian engineering surveying practice?
A.10 meters
B.20 meters or 30 meters
C.50 meters
D.100 feet
Explanation: As per Indian Standard IS 1492, metric survey chains are standardly manufactured in lengths of 20 meters (with 100 links) and 30 meters (with 150 links). Tallies are attached at regular meter intervals for rapid distance reading.
7In levelling surveying, what is the very first staff reading taken after setting up and levelling the instrument on a point of known elevation?
A.Intermediate Sight (IS)
B.Foresight (FS)
C.Backsight (BS)
D.Change Point (CP)
Explanation: Backsight (BS) is always the first staff reading taken after setting up and levelling the instrument. It is taken on a point of known elevation, such as a Benchmark (BM) or a Change Point, to determine the Height of Instrument (HI).
8Which type of shallow foundation is commonly provided for individual structural columns on firm soil?
A.Isolated Spread Footing
B.Pile Foundation
C.Well Foundation
D.Under-reamed Foundation
Explanation: An isolated spread footing is a shallow foundation used to support individual reinforced concrete columns when sound bearing soil is available at shallow depth. It spreads column loads over a sufficient soil area.
9What is the standard volumetric mix proportion of Cement : Fine Aggregate : Coarse Aggregate for M15 concrete grade?
A.1 : 1 : 2
B.1 : 1.5 : 3
C.1 : 2 : 4
D.1 : 3 : 6
Explanation: The nominal mix ratio for M15 grade concrete is 1 : 2 : 4 by volume (1 part cement, 2 parts fine aggregate/sand, and 4 parts coarse aggregate). M15 offers a characteristic 28-day strength of 15 N/mm².
10Which Personal Protective Equipment (PPE) is mandatory on all construction sites to protect workers from overhead falling objects?
A.Safety Helmet (Hard Hat)
B.Ear Plugs
C.Safety Goggles
D.Dust Mask
Explanation: A safety helmet (hard hat) is mandatory site safety gear designed to absorb impact and protect the head against falling materials, structural debris, and overhead hazards.
