B. G. Shirke Construction Technology Civil Supervisor Interview Questions and Answers

The percentage of steel in a pile varies depending on the type and design of the pile.

• The percentage of steel in a pile can range from 0% to over 90%.

• The type of pile (e.g. steel, concrete, timber) and its design (e.g. diameter, length, wall thickness) determine the percentage of steel.

• Steel piles typically have a higher percentage of steel than other types of piles.

• The percentage of steel in a pile can also affect its

Pile built-up above cut off level as per IS code

• IS code specifies the maximum allowable pile length above cut off level

• Pile length above cut off level should not exceed 3 times the pile diameter

• Built-up pile above cut off level can cause structural instability and failure

Vertical tolerance for piles as per IS code

• As per IS 2911-1:2010, the vertical tolerance for piles is +/- 25mm

• This tolerance is applicable for both driven and cast-in-situ piles

• The tolerance is measured at the top of the pile and at intervals of 3m along the length

• If the deviation exceeds the tolerance limit, the pile may need to be rejected or remedial measures taken

Pile concrete consumption tolerance depends on various factors.

• Pile diameter and length

• Concrete mix design

• Placement method

• Quality control measures

• Environmental conditions

• Tolerance typically ranges from 5-10% of estimated consumption

• Regular monitoring and adjustment of concrete consumption is necessary

Unit weight of steel is 7850 kg/m³

• The unit weight of steel is the weight of a specific volume of steel

• It is measured in kilograms per cubic meter (kg/m³)

• The unit weight of steel is 7850 kg/m³

• This value may vary slightly depending on the composition and manufacturing process of the steel

Rate analysis is the process of determining the unit cost of a particular item or activity in a construction project.

• Identify the item or activity to be analyzed

• Determine the quantity of materials and labor required

• Calculate the cost of materials and labor

• Add overhead costs and profit margin

• Divide the total cost by the quantity to get the unit rate

• Compare the rate with market rates to ensure competitiveness

Components to be considered in Rate analysis

• Cost of materials

• Cost of labor

• Cost of equipment

• Overhead expenses

• Profit margin

• Taxes and duties

• Transportation costs

• Wastage and spoilage

• Contingencies

• Productivity rates

• Market rates

• Inflation rates
