OPM stands for Optimum Moisture Content. If moisture content in soil is 20%, it will be at its ideal level for compaction.
OPM is the moisture content at which soil is most workable and compactable.
At 20% moisture content, soil will be at its optimum level for compaction.
Higher or lower moisture content can lead to poor compaction and stability issues.
CPM (Critical Path Method) and PERT (Program Evaluation and Review Technique) are project management tools used to plan and schedule tasks.
CPM is a deterministic model that calculates the longest path through a project's tasks to determine the minimum project duration.
PERT is a probabilistic model that uses three time estimates (optimistic, pessimistic, and most likely) to calculate the expected project duration.
Both C...
Density of steel, wood, and cement varies due to their composition and structure.
Steel has a density of around 7850 kg/m^3
Wood has a density ranging from 400-800 kg/m^3 depending on the type of wood
Cement typically has a density of 1440 kg/m^3

Core is the central part of a structure or object that provides strength and stability.
Core is commonly used in construction and engineering.
It is the central part of a building or structure that provides support and stability.
In fitness, core refers to the muscles in the abdomen, back, and pelvis that support the spine.
Examples of core materials include concrete, steel, and wood.
A strong core is important for maintain
Production refers to the process of creating goods or services using resources and labor.
Production involves transforming raw materials into finished products or providing services to customers.
It includes activities such as manufacturing, assembly, packaging, and distribution.
Examples of production include car manufacturing, food processing, and software development.
Efficient production is essential for businesses to

Different types of mix design include nominal mix, standard mix, and design mix.
Nominal mix design involves using standard ratios without testing.
Standard mix design follows specific guidelines and proportions.
Design mix design is customized based on specific project requirements.
Examples: M20, M30, M40 mixes.
Overlapping steel refers to the practice of placing steel bars on top of each other to increase strength and stability in construction.
Overlapping steel bars helps distribute loads evenly and prevent structural failure.
Properly overlapping steel bars is crucial for ensuring the structural integrity of a building.
Commonly used in reinforced concrete structures such as beams, columns, and slabs.
Overlap length and spacing...
The ratio of mortar for plaster work is typically 1:3 to 1:6, depending on the type of surface and desired finish.
The most common ratio for plaster work is 1 part cement to 3 parts sand.
For a smoother finish, the ratio can be adjusted to 1 part cement to 4 or 5 parts sand.
In some cases, a 1:6 ratio (1 part cement to 6 parts sand) may be used for rough surfaces or base coats.
Water should be added gradually to achieve th
The quantity of bricks in 50 square meters depends on the size of the bricks and the thickness of the wall being built.
Calculate the area of the wall in square meters
Determine the size of the bricks being used (e.g. standard size is 0.22m x 0.1m x 0.07m)
Calculate the number of bricks needed by dividing the wall area by the area of one brick
I applied via Walk-in and was interviewed in Feb 2022. There were 3 interview rounds.
Initial setting time of cement and high percentage required in sand are two different aspects of construction materials.
Initial setting time of cement refers to the time taken by cement to set and harden after mixing with water.
High percentage of sand is required in certain types of construction, such as concrete blocks and paving stones.
The percentage of sand required depends on the type of construction and the desire...
High percentage of sand is required for better compaction and stability of soil.
Sand helps in filling the voids between soil particles, increasing the density and reducing settlement.
A high percentage of sand also improves drainage and reduces the risk of soil erosion.
The ideal percentage of sand varies depending on the type of soil and the intended use of the construction project.
For example, for road construction, a ...

Cement consumption of M20 concrete mix ratio is 360 kg/m3.
M20 concrete mix ratio is 1:1.5:3 (1 part cement, 1.5 parts sand, 3 parts aggregate)
Cement consumption for 1 m3 of M20 concrete is 360 kg
To calculate total cement consumption, multiply 360 kg by the volume of concrete needed
Extra items added in billing should be justified with proper documentation and approval.
Ensure that the extra item was actually used on the project
Check if the extra item was approved by the client or project manager
Document the reason for adding the extra item in the billing
Provide evidence such as photos or receipts to support the inclusion of the extra item
Rate analysis involves calculating the cost of various items in a construction project.
Rate analysis helps in determining the cost of materials, labor, and equipment for each item in a project.
It involves breaking down the total cost into components like material cost, labor cost, machinery cost, and overheads.
Rate analysis is essential for accurate budgeting and cost estimation in construction projects.
For example, in...
