The unit of measurement for Rock Excavation is
Correct Answer
A. Cu m
Explanation
The unit of measurement for rock excavation is cubic meters (cu m). This is because rock excavation involves removing and excavating rock from the ground, and the volume of the excavated rock is measured in cubic meters. The cubic meter is a unit of volume that represents the amount of space occupied by the excavated rock. Other units of measurement such as square meters (sq m), running meters, or numbers (Nos.) are not suitable for measuring the volume of rock excavation.
2.
Which of the following is not a type of Estimate?
Correct Answer
C. Market rate Estimate
Explanation
The correct answer is "Market rate Estimate" because it is not a recognized type of estimate in the field of construction or project management. Plinth Area Estimate, Revised Estimate, and Supplementary Estimate are all commonly used types of estimates in construction projects. Plinth Area Estimate is based on the area of the building's plinth, Revised Estimate is an updated version of the initial estimate, and Supplementary Estimate is used when there are additional costs or changes to the project. However, Market rate Estimate does not fit into any of these categories and is not a commonly used term in estimating.
3.
Which of these Labour is not required for Refilling excavated earth in foundation ?
Correct Answer
C. Mason
Explanation
A mason is not required for refilling excavated earth in the foundation. Masons are skilled workers who specialize in building structures using bricks or stones. Their expertise lies in constructing walls, laying bricks, and handling masonry work. However, refilling excavated earth in the foundation does not involve any specialized masonry work. It is a task that can be performed by laborers (Mazdoors) or other workers who do not necessarily possess masonry skills. Therefore, a mason is not required for this particular task.
4.

5.
Quantity of dry mortar required for 11.67 cu.m Brickwork is
Correct Answer
A. 3.73 cu.m
Explanation
The correct answer is 3.73 cu.m. This means that 3.73 cubic meters of dry mortar are required for 11.67 cubic meters of brickwork.
6.
10 % (of Material cost) is added as Contractor's profit in rate analysis
Correct Answer
B. False
Explanation
In rate analysis, the contractor's profit is not added as a percentage of the material cost. The contractor's profit is usually added as a separate line item in the analysis, and it can vary depending on the project and the agreement between the contractor and the client. Therefore, the statement that 10% of the material cost is added as the contractor's profit in rate analysis is false.

Calculate the quantity of earthwork for 200 m length for a portion of road in an uniform ground , the heights of bank at two ends being 1.00 m and 1.60 m .The formation width is 10 m and side slopes is 2:1 . Assume that there is no transverse slope. (Use Mid Sectional Area Method)
Correct Answer
D. 3276 cu.m
Explanation
The Mid Sectional Area Method is used to calculate the quantity of earthwork for a portion of road. In this method, the quantity is calculated by finding the average of the end areas and multiplying it by the length of the portion. In this case, the average end area is calculated by taking the average of the areas of the two ends, which is (1.00 + 1.60)/2 = 1.30 m. The cross-sectional area is then calculated by adding the average end area to the formation width, which is 1.30 + 10 = 11.30 m. Finally, the quantity of earthwork is calculated by multiplying the cross-sectional area by the length of the portion, which is 11.30 * 200 = 2,260 cu.m. However, since the side slopes are 2:1, the quantity needs to be multiplied by 2, resulting in 2,260 * 2 = 4,520 cu.m. But since there is no transverse slope, the quantity is divided by 2, resulting in 4,520 / 2 = 2,260 cu.m. Therefore, the correct answer is 3276 cu.m.

An old building has been constructed by a person at a cost of Rs. 10,00,000 /- excluding the cost of land . Calculate the amount of annual sinking fund at 4% interest assuming the future life of the building as 20 Years and the scrap value of the building is 10 % of the cost of construction.
Correct Answer
C. 30,223.58 Rs/-
Explanation
The annual sinking fund can be calculated using the formula:
Annual sinking fund = (Cost of construction - Scrap value) * Interest rate / (1 - (1 + Interest rate)^(-number of years))
In this case, the cost of construction is Rs. 10,00,000, the scrap value is 10% of the cost of construction (Rs. 10,00,000 * 10% = Rs. 1,00,000), the interest rate is 4%, and the number of years is 20.
So, the annual sinking fund = (10,00,000 - 1,00,000) * 4% / (1 - (1 + 4%)^(-20)) = Rs. 30,223.58
Therefore, the correct answer is 30,223.58 Rs/-.

A Property fetches a net annual income of Rs. 1,97,000 /- deducting all the outgoings. workout the capitalized value of the property if the annual rate of interest is 5.68 %
Correct Answer
A. 34,68,309.86 Rs/-
Explanation
The capitalized value of a property is calculated by dividing the net annual income by the annual rate of interest. In this case, the net annual income is Rs. 1,97,000 and the annual rate of interest is 5.68%. Dividing Rs. 1,97,000 by 0.0568 (5.68%) gives us Rs. 34,68,309.86, which is the capitalized value of the property.
