Estimating And Costing — Part 1 MCQs with Explanations

We're asked to find the volume of box cutting needed for a concrete road. Think of "box cutting" as the amount of soil we need to remove (excavate) to create space for the road. The road is made of two layers: 1. A 15 cm thick concrete layer . 2. A 10 cm thick gravel sub-base layer . Box cutting is all about how much earth you need to remove, so we only care about the final dimensions of the road profile. So, we need to consider both layers (concrete and gravel) to determine the total depth of the excavation. 1. Calculate the total thickness: The total thickness is 15 cm (concrete) + 10 cm (gravel) = 25 cm. We need to convert this to meters: 25 cm = 0.25 m 2. Calculate the volume: Volume is calculated by: Length x Width x Height (or Thickness in this case) Length = 1000 m Width = 8 m Thickness = 0.25 m Volume = 1000 m x 8 m x 0.25 m = 2000 m 3 Therefore, the correct answer is Option D: 2000 m 3

Definition: A detailed estimate is a comprehensive calculation of the quantities and costs of all items required for the execution of a construction project. Main factors: While preparing a detailed estimate, several aspects must be considered, including the quantity of materials , their availability , and the transportation arrangements to the site. Reason: The quantity of materials directly affects the total cost and ensures sufficient supply for uninterrupted work. The availability of materials determines procurement timelines and can influence choice of suppliers and scheduling. The transportation of materials impacts delivery efficiency, cost, and timely completion of the project. Conclusion: All these factors are interlinked and crucial for accurate cost estimation and smooth project execution, hence all the above is the correct answer.

The correct answer is Option B: Partly in excavation and partly in embankment . In canal engineering, berms are provided when they are partly in excavation and partly in embankment. This is done to stabilize the slopes of the canal and prevent erosion. Berms act as horizontal shelves on the sides of the canal, providing support to the excavated and embanked portions. Option A: Fully in excavation is incorrect because berms are not exclusively in excavation. Option C: Fully in embankment is incorrect because berms are not exclusively in embankment. Option D: All the above is incorrect because the correct condition for providing berms is when they are partly in excavation and partly in embankment, not fully in either.
