Whenever you are planning for a factory building you should keep following points in your mind for making factory building as efficient as possible. Energy efficient means maximum use of daylight, ventilation and heat insulation in the building with fulfillment of its functional requirements. Most important orientation of building should...
50 Civil Engineering MCQs for Competitive exams: Wall footings is a type of spread foundation. In arches and lintels, soffit is the under surface of an arch. Residential buildings belonging to group ‘A’ according to the National Building Code. The piles driven at an inclination to resist inclined loads are...
Important Civil Engineering Questions asked in Competative Exams: For a 30 degree cranked or bend up bar, the inclined length of the crank is equal to 2d. Wind load analysis can be done by using IS 875- part 3. Temporary spurs are also called bunds. The Unified Soil Classification System...
Types of tunnels with detailed explanation:- The Circular section offers greater resistance to external pressure and highly suitable for unstable ground such as sand or soft clay. They are not used as traffic tunnels because they require more filling to make flat base, hence used for carrying water and sewage...
Types of Supports in Structural Engineering:- 1. Roller Support: This type of support is mainly used for steel trusses of the bridges, which have one of their end supported on rollers. These rollers allows the movement of the beams towards left or right on account of expansion or contraction, due...
If through investigation we found that the shallow soil is unstable and weak( means the bearing capacity of soil is not satisfactory) then pile foundation is considered. And also the pile foundation is cheaper than any other ground improvement cost. Piles are also give better results in jetties or bridge...
Least Count is the ratio of smallest value of one division on the main scale to number of divisions on vernier scale. Least Count for Dial Gauge = Smallest value of one division on the main scale (i.e. on small hand dial gauge)/ Total number of divisions on long hand...
Lintel:- It is a horizontal member which is placed just above the opening to resist loads acting over the opening and transfer loads to supporting walls. And it acts like a beam. Types of lintels are:- Timber or wood lintel:- they are made up of timber pieces and generally used...
Determinate structure Indeterminate structure 1. When all forces in a structure is determined from equilibrium equations, the structure is known as statically determinate. When the unknown forces in a structure are more than the available equilibrium equations, that structure is known as statically indeterminate structure. 2. Support will not develop...

DETERMINATION OF MOISTURE (WATER) CONTENT(W) IN SOIL BY USING OVEN DRY METHOD Objective Determine the natural moisture content of the soil sample. Definition:-It is the ratio of the weight of the water to the weight of solids in soil mass and it is generally expressed in percentage and usually done...
S.No. Line of Collimation or HI method Rise and fall method Rise and fall method 1 It is more rapid and saves a considerable time and labour. It is laborious as the staff reading of each station is compared, to get a rise or fall. 2 It is well adopted...
Primary divisions of surveying are: Plane Surveying Geodetic Surveying Plane Surveying Geodetic Surveying The surveying in which earth surface is considered as plane surface. The surveying in which curvature/surface of the the earth is considered as curved surface. Earth’s curvature is ignored. Earth’s curvature is considered. The line joining any...
Tests used to find out Workability of a freshly mixed concrete are: Slump cone test Vee bee test Compaction factor test Slump test is performed on freshly mixed concrete to find out the water content and workability or consistency of concrete. The test is useful in controlling quality of the...
