What is height of instrument and Rise & fall method of levelling?
AdityaBhandakkar
In simple English, The height of instrument always measures form benchmark. The benchmark is a Point on the sea derived from mean sea level. Rise and Fall method: The rise and fall of ground between two adjacent ranging rod are measures with levelling staff. High reading= fall of ground level. Low rRead more
In simple English,
The height of instrument always measures form benchmark.
The benchmark is a Point on the sea derived from mean sea level.
Rise and Fall method:
The rise and fall of ground between two adjacent ranging rod are measures with levelling staff.
RL = HI – FS
RL= Reduced level
HI = Height of instrument
FS= Foresight distance.

AdityaBhandakkar
Now you can use the aggregate between sieve size 10mm retaining and passing from 12.5 mm.use locally available materials to reduce cost. Still, the mix design does not change but gives the desired result.

Convert Cubic Meter of Laterite to Tonnes.
AdityaBhandakkar
IS code gives various tests to measure the density of materials. Calculate the density of laterite. It is approx. 1019kg/m^3. Using formula: Density = mass/ volume Result: 1 kg/m^3 = 10^-3 tonne. 1.019 tonnes per m^3
IS code gives various tests to measure the density of materials.
Calculate the density of laterite.
It is approx. 1019kg/m^3.
Using formula:
Density = mass/ volume
In construction Project, What is the meaning of the term Float?
AdityaBhandakkar
In construction management, the float is defined as a difference between the early start and late start of construction activity. Float is a delayed in time for a particular activity in construction, without affecting the deadline of completion of the project. Suppose P, Q and R are three activitiesRead more
In construction management, the float is defined as a difference between the early start and late start of construction activity.
Float is a delayed in time for a particular activity in construction, without affecting the deadline of completion of the project.
Suppose P, Q and R are three activities scheduled to complete in 10,15 and 20 days, respectively. C should be started only after completion of A and B.
P and Q be done parallel, then 15 – 10= 5 days are called ‘Float’.
In the float period, all labor strength focuses on working activity.

AdityaBhandakkar
Volume batching does a not accurate result. The voids are present in a large amount which affects the result. Literally, nowadays volume batching is avoided even for small projects. Slump- Low to high Less strength at 7 days and 28 days Swelling of sand affects on 7 and 28 days strength of concrete.Read more
Volume batching does a not accurate result. The voids are present in a large amount which affects the result. Literally, nowadays volume batching is avoided even for small projects.
Weight batching give us an accurate and precise result, which also decrease construction problems in future.
In weight batching, we actually measured a mass of sand.
What is the Incoherence soil canal?
AdityaBhandakkar
Word itself describes the meaning. Incoherent indicated less amount of cohesive force between granules. Incoherent sand is consolidated sand with very less cohesion between granular particles. It makes sand more porous. If canal flows from the incoherent canal, incoherent alluvial soils scoured as fRead more
Word itself describes the meaning.
Incoherent indicated less amount of cohesive force between granules.
Incoherent sand is consolidated sand with very less cohesion between granular particles. It makes sand more porous.
If canal flows from the incoherent canal, incoherent alluvial soils scoured as fast as it was deposited.
Incoherent sand has

It is also called as Stabilization pond or waste stabilization lagoons. It is a man-made earthen structure. Sludge seRead more
Water stabilization pond(WSP)
It is pond designed and builds to remove organic impurities and remove harmful substances like pathogens, algae form water and make it palatable.
It is also called as Stabilization pond or waste stabilization lagoons.
It is best for developing countries where has a warm climate. Industrial pollutants and sewage should treat economically.
There are many ponds designed in series for various functions.
There are three types of stabilization ponds
