Past Questions
In sewage treatment plants, the oil and grease is removed by:
A)
filtration
B)
oxidation
C)
screening
D)
skimming
In sewage treatment plants, oil and grease are lighter than water and float on the surface. They are therefore removed by skimming, where the floating layer is collected from the top. Filtration is used for solids, oxidation for organic matter decomposition, and screening removes large debris, not oil and grease.
Which wood should be used for first class building chaukhats?
A)
Sesame wood
B)
Saal wood
C)
Teak wood
D)
Arjun wood
For first-class building chaukhats (door/window frames), durable, strong, and termite-resistant timber is preferred. Teak wood is widely used for high-quality construction work because it has excellent strength, durability, and resistance to decay. Saal and sesame wood are also strong timbers, but teak is the standard choice for first-class chaukhats. Arjun wood is not generally preferred for this purpose.
What if the full form of HVAC?
A)
Heating Ventilation and Air Conditioning
B)
Heating Ventilation and Cooling
C)
Humidity Ventilation and Air Conditioning
D)
Humidity Ventilation and Air Cooling
HVAC is the standard acronym in building services for Heating, Ventilation and Air Conditioning. Option (a) matches the correct expansion. The other options are incorrect because they replace Air Conditioning with Cooling or use Humidity instead of Heating.
As per Council of Architecture Schedule of Payment, how much percentage of payment can be received at stage 1?
A)
10 %
B)
12 %
C)
15 %
D)
18 %
As per the Council of Architecture’s Schedule of Payment, Stage 1 payment is 10% of the total fee. This is the first installment after the initial brief/briefing and basic planning stage. Therefore, option (a) 10% is correct. The other options do not match the standard COA payment schedule.
In Leopold Interaction Matrix, what does M signify?
A)
Management
B)
Mass
C)
Momentum
D)
Magnitude
In the Leopold Interaction Matrix used for Environmental Impact Assessment, the two axes represent the project actions and environmental factors. The letter 'M' commonly signifies 'Management' in this context. The other options—Mass, Momentum, and Magnitude—do not relate to the standard terminology of the Leopold Matrix.
For initial calculation of an RCC beam design, the depth is assumed to be
A)
1/8th of span
B)
1/20th of span
C)
1/15th of span
D)
1/10th of span
For preliminary or initial design of an RCC beam, the overall depth is commonly assumed as about span/12 to span/15, depending on loading and support conditions. Among the given options, 1/15th of span is the standard approximation used for initial calculations. The other values are either too shallow (1/20th) or too deep (1/10th, 1/8th) for a typical RCC beam estimate.
Sewers are designed to run
A)
Partially/ half full
B)
Full
C)
2/3rd full
D)
1/3rd full
Sewers are generally designed to run partially full, approximately half full, rather than completely full. This allows for ventilation, free flow, and some margin to handle fluctuations in sewage flow. If a sewer runs full all the time, pressure flow can occur, which is not desirable in normal gravity sewer design. Hence, option (a) is correct.
What does the term VRF stand for?
A)
Variable refrigerant flow
B)
Variating refrigerant flow
C)
Variable refrigerant floor
D)
Variant refrigerant flow
VRF is the standard HVAC abbreviation for Variable Refrigerant Flow, a system that varies the amount of refrigerant sent to indoor units based on demand. The other options are incorrect because they use nonstandard words or wrong terms ('variating', 'floor', 'variant').
The floor of a septic tank should be sloping towards
A)
the inlet side
B)
the outlet side
C)
should not be sloping
D)
should be lowest at the middle of the tank
In a septic tank, the floor is made to slope slightly towards the outlet side so that sludge can move toward the sludge-digestion zone and be removed more easily during cleaning. A slope toward the inlet would oppose flow and cause unwanted accumulation near the inlet. The floor should also not be flat or lowest at the middle, as that would not help sludge collection and maintenance.
How many times can a notice of change of office address of an Architect be published?
A)
2
B)
3
C)
4
D)
5
Under the Council of Architecture (Professional Conduct) Regulations, an architect may publish a notice regarding change of office address a limited number of times. The permitted maximum is 5 times. Therefore, option (d) is correct.
Why others are incorrect:
- (a) 2: less than the permitted limit
- (b) 3: less than the permitted limit
- (c) 4: less than the permitted limit
- (d) 5: matches the prescribed maximum
For one way slab, the ratio in between length and breadth of the slab should be
A)
less than 1
B)
between 1.0 to 1.5
C)
less than 2
D)
more than 2
A one-way slab is defined as a slab in which the longer span is more than twice the shorter span, i.e., the ratio of length to breadth is greater than 2. In such slabs, load is mainly carried in one direction. If the ratio is less than 2, the slab behaves as a two-way slab. Therefore, the correct option is 'more than 2'.
Aeration of water is done to remove
A)
Odour
B)
Colour
C)
Bacteria
D)
Hardness
Aeration is the process of bringing water into contact with air to remove dissolved gases and volatile substances, especially those causing bad taste and odour. It is commonly used to strip off gases like hydrogen sulfide and improve water quality. It does not remove colour, bacteria, or hardness directly.
How many levels of rating does the Indian Green Building Council have for residential sectors?
A)
4
B)
5
C)
3
D)
6
The Indian Green Building Council (IGBC) residential rating system has 5 levels: Certified, Silver, Gold, Platinum, and Net Zero/Platinum+ depending on the specific framework, but for the standard residential sector rating the commonly cited levels are 5. Therefore, the correct option is 5. The other options do not match the IGBC residential rating structure.
Which of the following is considered a negative environmental impact?
A)
Green spaces
B)
Pedestrian pathways
C)
Construction noise
D)
None of these
Negative environmental impacts are harmful effects on the environment or human well-being. Construction noise causes noise pollution and disturbs nearby residents, wildlife, and activities, so it is a negative impact. Green spaces and pedestrian pathways are generally positive environmental measures because they improve ecology, reduce pollution, and support sustainable mobility. Therefore, the correct answer is construction noise.
Which of the following valves is used to maintain pressure in the system?
A)
Pressure relief valve
B)
Check valve
C)
Manual control valve with variable flow plug
D)
Pneumatic control valve with variable-flow plug
A pressure relief valve is specifically used to maintain system pressure by opening automatically when the pressure exceeds a preset limit and releasing excess pressure. This protects the system from overpressure and keeps pressure within a safe range. A check valve only prevents reverse flow, while manual and pneumatic control valves regulate flow, not directly maintain pressure.
While calculating the handling capacity of lift, the weight of a person is taken as
A)
60 kg
B)
62 kg
C)
64 kg
D)
68 kg
In lift traffic/handling-capacity calculations, the standard average weight of one person is taken as 68 kg. This is the conventional design value used in building services for estimating passenger load. Therefore, option (d) is correct.
Slenderness ratio is expressed with the Greek letter
A)
lambda (l)
B)
alpha (a)
C)
gamma (g)
D)
mu (m)
In Strength of Materials, the slenderness ratio of a column is commonly denoted by the Greek letter lambda, written as λ. It is defined as the ratio of effective length to the least radius of gyration, i.e. λ = Le / k. Therefore option (a) is correct. The other symbols alpha (α), gamma (γ), and mu (μ) are used for other engineering quantities, not for slenderness ratio.
As per NBC 2006 norms, provision of lifts shall be made for buildings ________m or more in height.
A)
15m
B)
18m
C)
12m
D)
20m
As per NBC 2006, lifts are required to be provided in buildings of 15 m or more in height. Hence, the correct option is (a) 15m. The other options (12 m, 18 m, and 20 m) do not match the NBC 2006 threshold for lift provision.
Young’s Modulus of elasticity is
A)
Tensile stress / Tensile strain
B)
Shear stress / Shear strain
C)
Tensile stress / Shear strain
D)
Shear stress / Tensile strain
Young’s modulus of elasticity is defined as the ratio of tensile (or normal) stress to tensile strain within the elastic limit. Mathematically, E = stress / strain. Option (b) is the definition of modulus of rigidity (shear modulus), while (c) and (d) mix different types of stress and strain incorrectly.
What is the maximum letter size allowed for advertisement for an Architect in an office or construction site?
A)
9 cm
B)
9.5 cm
C)
10 cm
D)
10.5 cm
The standard limit for lettering size in an architect’s advertisement/signboard at an office or construction site is 10 cm. Hence option (c) is correct. The other options (9 cm, 9.5 cm, and 10.5 cm) do not match the prescribed maximum size.
Prestressed concrete means
A)
compressive stress induced in concrete before loading
B)
compressive stress induced in steel before loading
C)
tensile stress induced in steel before loading
D)
none of these
Prestressed concrete is concrete in which internal stresses are introduced before the application of external loads. These prestresses are usually compressive stresses induced in the concrete (through tensioned steel tendons) so that the concrete can better resist later tensile stresses from service loads. Option (b) is incorrect because the aim is not to prestress steel itself, and option (c) describes tension in steel, which is the means used to create prestress, not the definition of prestressed concrete.
As per Council of Architecture Schedule of Payment, how many stages of payment are there excluding retainer?
A)
5
B)
6
C)
7
D)
8
As per the Council of Architecture (COA) Schedule of Payment, the payment is typically divided into 7 stages in total, including the retainer. If the retainer is excluded, the remaining stages of payment are 6. Hence, option (b) is correct. The other options do not match the standard COA fee schedule structure.
What does Turbidity of raw water measure?
A)
Suspended solids
B)
Acidity of water
C)
B.O.D
D)
Repair Work
Turbidity indicates the cloudiness or haziness of water caused mainly by fine suspended particles such as silt, clay, organic matter, and microorganisms. Therefore, it measures suspended solids in raw water. Acidity is measured by pH, B.O.D. measures oxygen demand due to biodegradable organic matter, and repair work is unrelated.
In RCC beams, the end cover of concrete should not be less than
A)
15 mm
B)
20 mm
C)
25mm
D)
30 mm
In RCC beams, the end cover is the minimum concrete cover provided at the ends of reinforcement to protect steel from corrosion and fire. As per standard practice for RCC beams, the end cover should not be less than 20 mm. Hence, option (b) is correct. The other options are either too small to ensure proper protection or exceed the usual minimum requirement.
What is the pipe diameter of domestic water supply from distribution point to home?
A)
20mm
B)
25mm
C)
30mm
D)
10mm
For domestic water supply from the distribution point to a home, the usual service connection pipe diameter is 25 mm. A 10 mm pipe is too small for normal domestic supply, while 20 mm is more typical for smaller service lines; 30 mm is not the standard option here. Hence, 25 mm is the correct answer.
