Q5. What is the process of tendering?

Ans.

Tendering is the process of inviting bids from suppliers to provide goods or services at a specified price.

  • Identify the need for goods or services

  • Prepare tender documents outlining requirements and specifications

  • Invite bids from potential suppliers

  • Evaluate bids based on criteria such as price, quality, and delivery time

  • Award the contract to the successful bidder

Q6. How do you do rate analysis

Ans.

Rate analysis involves calculating the rates of various items in a construction project to determine the overall cost.

  • Gather detailed information on the quantities and specifications of materials, labor, and equipment required for the project.

  • Determine the unit rates for each item by considering factors such as market prices, labor costs, and equipment rental rates.

  • Calculate the total cost of each item by multiplying the quantity required by the unit rate.

  • Sum up the total cos...read more

Q7. What is the Area of Given figure

Ans.

The area of a figure can be calculated by multiplying its length by its width or using the appropriate formula for the specific shape.

  • For a rectangle, the area is calculated by multiplying its length by its width: Area = length x width

  • For a circle, the area is calculated using the formula: Area = π x radius^2

  • For a triangle, the area is calculated using the formula: Area = 0.5 x base x height

  • For irregular shapes, the area can be calculated by dividing the shape into smaller, m...read more

Q8. WHAT IS SINGLE PHASE SUPPLY 230V

Ans.

Single phase supply is a type of electrical power distribution that uses a single alternating current (AC) waveform.

  • Single phase supply has only one voltage waveform that alternates in a sinusoidal manner.

  • It is commonly used in residential and small commercial applications.

  • The voltage of a single phase supply is typically 230V in Europe and 120V in North America.

  • Single phase supply is not suitable for high power applications and three phase supply is used instead.

Q10. Explain earth potential rise?

Ans.

Earth potential rise is the increase in voltage that occurs when a large current flows into the ground.

  • Occurs when a large current is injected into the ground

  • Can be caused by lightning strikes, fault currents, or power system faults

  • Can lead to dangerous touch and step potentials

  • Important to consider in grounding and lightning protection systems

Q11. What is Kirchof Law

Ans.

Kirchhoff's Law states that the total current entering a junction is equal to the total current leaving the junction.

  • Kirchhoff's Current Law (KCL) states that the algebraic sum of currents entering a node is zero.

  • Kirchhoff's Voltage Law (KVL) states that the sum of voltage drops in a closed loop is equal to the applied voltage.

  • These laws are fundamental in analyzing electrical circuits and are used to solve circuit problems.

  • KCL and KVL are essential for determining unknown cu...read more
