I applied via Campus Placement and was interviewed in Jul 2022. There were 3 interview rounds.
Initial setting time of cement is the time taken for the cement paste to harden sufficiently to resist certain specified pressure.
Initial setting time is an important property of cement as it determines the time available for mixing, placing, and finishing of concrete.
It is measured by the Vicat apparatus, which consists of a needle and a mould filled with cement paste.
The initial setting time is typically around 30 mi...
The size of a concrete cube refers to its dimensions, typically measured in millimeters.
The size of a concrete cube is usually specified by the engineer or client.
Common sizes for concrete cubes are 150mm, 200mm, and 300mm.
The size of the cube is important for testing the compressive strength of the concrete.
The cubes are typically cast and cured for a specific period before testing.
The minimum diameter for dowel bars depends on the specific application and design requirements.
The minimum diameter for dowel bars is typically specified in the project's design documents or specifications.
It is important to consider factors such as the load transfer requirements, concrete strength, and spacing between dowel bars when determining the minimum diameter.
In general, dowel bars for pavement joints are comm...
The lap length of bars for compression zone is the minimum length required to ensure proper transfer of stress between two overlapping bars.
The lap length is determined based on the diameter of the bars, concrete strength, and the bond strength between the bars and concrete.
It is important to provide adequate lap length to prevent failure due to inadequate bond between the bars and concrete.
The lap length for compressi...
The minimum allowable pH value of water is 6.5.
The minimum allowable pH value of water is determined by various regulatory bodies and standards.
For drinking water, the World Health Organization recommends a minimum pH of 6.5 to prevent corrosion of pipes and plumbing fixtures.
In some industrial processes, a minimum pH of 6.0 or even lower may be required.
Water with a pH below the minimum allowable value may be consider...

I applied via Walk-in and was interviewed in Mar 2023. There was 1 interview round.
The weight of steel varies with its diameter.
The weight of steel can be calculated using the formula: weight = volume x density
The density of steel is approximately 7850 kg/m³
The volume of steel can be calculated using the formula: volume = pi x (diameter/2)² x length
For example, a 10mm diameter steel rod with a length of 1 meter would weigh approximately 0.393 kg
Waterproofing is the process of making a structure or object resistant to water penetration.
Identify the areas that need waterproofing such as roofs, walls, and foundations.
Clean and prepare the surface to be waterproofed.
Apply a waterproofing membrane or coating such as bituminous, acrylic, or polyurethane.
Ensure proper drainage and slope to prevent water accumulation.
Test the waterproofing system for leaks and make n...

Deduction in shuttering criteria refers to the reduction in the amount of shuttering material used in construction.
Deduction in shuttering criteria is done to reduce the cost of construction.
It is also done to reduce the time taken for construction.
The deduction is usually done based on the strength of the concrete being used.
For example, if the concrete strength is high, less shuttering material is required.
The deduct...

Interior change in drawing refers to modifying the internal elements of a design or blueprint.
Identify the specific elements that need to be changed
Consider the impact of the changes on the overall design
Update the drawing with the new interior layout
Ensure that the changes align with the project requirements
I appeared for an interview before Jul 2024, where I was asked the following questions.
Excavation unit measurements include volume, area, and depth, crucial for project planning and cost estimation.
Cubic meters (m³) - Commonly used to measure the volume of soil to be excavated.
Square meters (m²) - Used for measuring the area of the excavation site.
Depth in meters (m) - Important for determining how deep the excavation needs to go.
Tons - Sometimes used to estimate the weight of the excavated material.
Effective rate escalation management in tenders involves strategic planning, clear communication, and regular monitoring.
Establish a clear escalation clause in the tender documents to define conditions for rate adjustments.
Regularly review market trends and material costs to anticipate potential escalations.
Implement a transparent communication process with stakeholders to discuss any necessary adjustments.
