Correct Answer: It is measured as per drawing stating thickness. The description must include framework, finishing, curing, etc.

Explanation:

For Damp Proof Course (DPC) in civil engineering measurement:

DPC is measured in square meters (m²) with specified thickness mentioned in the description.

The description also includes details like formwork (if any), finishing, curing, and method of application.

Why others are incorrect:

• Not measured in cubic meter → DPC is not a volume item.

• Does not include grouting → Grouting is a separate item.

• Volume of material is not measured → Only area with thickness is considered.

So, the true statement is:

It is measured as per drawing stating thickness. The description must include framework, finishing, curing, etc.

The plastic design method requires less stringent lateral bracing compared to elastic design, which is a correct statement making option 4 the false statement about its limitations.

Correct Answer: 76%

Explanation:

As per IS 1343:2012 (Prestressed Concrete Code of Practice):

This limit is provided to:

• Avoid overstressing the prestressing steel

• Prevent damage during jacking

• Ensure safe transfer of prestress

Hence, the correct answer is: 76%

Carrying out the centroid calculation for both rectangles yields:

This matches the highlighted answer.

Correct Answer: Declination

Explanation:

The horizontal angle between the magnetic meridian and the true meridian is called magnetic declination.

• If the magnetic north lies east of true north → East Declination

• If the magnetic north lies west of true north → West Declination

Hence, the correct option is: Declination

To compute the earthwork in excavation, we must find the perimeter of the trench and multiply by width × depth.

Given:

• Room size = 5 m × 6 m

• Wall thickness = 0.20 m

• Foundation trench width = 0.60 m

• Foundation depth = 0.80 m

Step 1: Find center-to-center dimensions

Since the wall thickness is 20 cm = 0.2 m,

Add wall thickness to room dimensions:

• Length (outer) = 6 + 0.2 = 6.2 m

• Width (outer) = 5 + 0.2 = 5.2 m

These are the outer dimensions of trench.

Step 2: Perimeter of trench

Step 3: Volume of excavation

✅ Correct Answer: 10.94 cu. m.

Correct Answer: The phase difference between the transmitted and the reflected electromagnetic waves

Explanation:

Modern Electronic Distance Measurement (EDM) instruments operate by:

• Transmitting an electromagnetic (EM) wave

• Receiving the reflected wave back

• Comparing the phase difference between the transmitted and received signals

Using this phase shift, the instrument calculates the distance accurately.

Hence, the correct option is: The phase difference between the transmitted and the reflected electromagnetic waves

To find the speed of the vehicle, we use the basic relation for rate of change of super-elevation (se):

Now, speed:

✅ Correct Answer: 9.3 m/s

To calculate the development length (Ld), we use the formula:

(For deformed bars, it increases by 60%. Since not mentioned, we use standard value.)

Now calculate Ld

≈ 53.5 mm

✅ Correct Answer: 53.5 mm

For long-term deflection calculation, factors like creep, elasticity, and age of the concrete are crucial, whereas the thermal expansion coefficient is not typically considered.
