This set of Civil Engineering Drawing Multiple Choice Questions & Answers (MCQs) focuses on “Types of Construction and Specification”.
1. The water proof mud- plaster consists of _______________
b) janta Emulsion
d) soil, janta emulsion and cowdung
Explanation: Soil – soil should not be too much clayey nor too much sandy ( 50% clay and 50% sand are suitable). Weight of dry earth should do about 112 kg per cu m ( 70 lbs per cu ft).
Bhusa – About 60% of bhusa by weight of dry soil is to be mixed.
Cowdung – It should be used for surface finishing.
Janta Emulsion – 5% of janta emulsion by weight of dry soil is to be mixed.
2. For fourth class building roofing shall be of __________over bamboo and wooden supports.
a) mud roof
b) tile roof
c) wooden roof
d) bamboo roof
Explanation: Roof tiles are designed mainly to keep out rain, and are traditionally made from locally available materials such as terracotta or slate. Modern materials such as concrete and plastic are also used and some clay tiles have a waterproof glaze. Roof tiles are ‘hung’ from the framework of a roof by fixing them with nails.
3. The brick work is not measured in cu m in case of __________
a) one or more than one brick wall
b) brick work in arches
c) reinforced brick work
d) half brick wall
Explanation: Half brick wall is measured in sq m.
4. The excavation exceeding 1.5 m in width and 10 sq. m in plan area with a depth not exceeding 30 cm, is termed as __________
b) surface dressing
c) surface excavation
Explanation: Surface dressing is done upto 15 cm depth and surface excavation upto 30 cm depth.
5. Specifications are of two types- General specification or brief specification and __________________
a) short specification
b) general specification
c) detailed specification
d) brief specification
Explanation: The detailed specification of an item of work specifies the qualities and quantities of materials, the proportion of mortar, workmanship, the method of preparation and the execution and the method of measurement. The detailed specification of different items of work are prepared separately, and describe what the works should be and how they shall be executed and constructed.
6. Stabilized soil wall is cued for ______ to ______ days by sprinkling water.
a) 3 to 6
b) 15 to 20
c) 7 to 10
d) 20 to 35
Explanation: An appropriate type of chosen soil, when compacted at optimum moisture content, can be made strong and durable by the addition of a stabilizing agent. Stabilisation enables the soil to retain its shape and a significant proportion of its strength even when wetted to the point of saturation.
7. The estimate which prepared using any rough method to get the approximate cost construction anticipated in a project is called an ______________estimate.
Explanation: The approximate estimate is done in order to find out an approximate cost in very short time before starting the project. The estimation is made before selecting the final specification and design of the project. This method is also known as preliminary or rough estimate.
8. The roofing cannot be made with slate.
Explanation: Slate can be made into roofing slates, a type of roof shingle, or more specifically a type of roof tile, which are installed by a slater. Slate has two lines of breakability – cleavage and grain – which make it possible to split the stone into thin sheets. When broken, slate retains a natural appearance while remaining relatively flat and easy to stack.
9. Average number of blocks required for a two-roomed house is about 2500.
Explanation: More recently, an improved version has been designed and marketed by Aeroweld Industries, B-9 HAL Industrial Estate, Bangalore – 560 037. The size of the blocks is 30.5 cm x 14.4 cm x 10 cm or 23 cm x 19 cm x I0 cm. One such machine can be utilised to make 300 – 500 blocks per day by four unskilled workmen.
10. Before applying water proof mud plaster, the joints should not be scrapped.
Explanation: Before applying water proof mud plaster, the joints should be scrapped and wall surface should be cleaned and made damp by sprinkling water and then plaster should e applied.
11. For preparation of subgrade the existing subgrade should be dressed to a camber of 1 in 24 to 1 in 32.
Explanation: It is watered and allowed to soak for the night if necessary, and rolled with 8 to 10 tonne road roller. The density of the compacted soil should not be less than 1.8 gm /c.c. up to at least 6” depth.
12. For making bund ordinary mud wall gonda ( bund) about 8” * 6” shall be made on the sides.
Explanation: Bunding, also called a bund wall, is a constructed retaining wall around storage “where potentially polluting substances are handled, processed or stored, for the purposes of containing any unintended escape of material from that area until such time as remedial action can be taken.
