Construction Planning And Management — Part 1 MCQs with Explanations

Bar charts (also called Gantt charts ) are simple graphical schedules used to show the start time, finish time, and duration of different construction activities. They are best suited for minor or small construction works because the number of activities is limited, making the schedule easy to prepare and understand. For large or complex projects , bar charts become difficult to manage since they do not clearly show the relationship or dependency between activities . In such cases, network planning techniques like PERT (Program Evaluation and Review Technique) or CPM (Critical Path Method) are preferred. Easy Trick to Remember: Small Project → Bar Chart Large Project → PERT / CPM Hence, bar charts are most suitable for minor works , making Option A the correct answer.

This is the correct answer. In construction project management using a bar chart (Gantt chart), each activity is represented by a horizontal bar. The activities mentioned in the question include: 1. Supply of materials for concrete 2. Formwork, reinforcing, and placing of concrete 3. Removal of formwork 4. Curing of concrete Each of these activities requires a separate bar on the chart.

Let's look at each option: Option A: Moist loam: Loam is generally a good soil type for digging, especially when moist. So, output would be relatively good. Option B: Sand and gravel: Sand and gravel are loose materials, easy to dig. Output would be high. Option C: Good common earth: This is also generally good for digging, so output would be decent. Option D: Wet sticky clay: Wet sticky clay is the most difficult material to dig and load. It sticks to the bucket, making it hard to empty and reducing the amount of material that can be moved per cycle. Therefore, the answer is Option D: Wet sticky clay because it offers the least ideal digging conditions, leading to the lowest output.

In Civil Engineering, works costing less than Rs. 20,000 are typically categorized as Petty works . These are small-scale projects of minor significance that require minimal resources and planning. Therefore, the correct option is D: Petty works .

The double declining balance (DDB) method is an accelerated depreciation method that depreciates the asset faster in the earlier years. The formula for DDB depreciation is: Depreciation for the year = 2 × (1 / useful life) × book value at beginning of year Given: Cost of excavator = Rs. 20,00,000 Estimated life = 8 years Salvage value = Rs. 0 Depreciation rate = 2 × (1 / 8) = 25% Year 1: Depreciation = 25% of 20,00,000 = Rs. 5,00,000 Book value at end of Year 1 = 20,00,000 - 5,00,000 = Rs. 15,00,000 Year 2: Depreciation = 25% of 15,00,000 = Rs. 3,75,000 Book value at end of Year 2 = 15,00,000 - 3,75,000 = Rs. 11,25,000 Year 3: Depreciation = 25% of 11,25,000 = Rs. 2,81,250 Book value at end of Year 3 = 11,25,000 - 2,81,250 = Rs. 8,43,750 Therefore, the correct answer is: Rs. 8,43,750 (Option A).

Power stations are large-scale projects involving the installation of heavy machinery, boilers, turbines, generators, and complex control systems. Such projects require specialized design, skilled manpower, and coordinated construction of structural, mechanical, and electrical components . Because power stations are built to support industrial-level production of energy , they are classified under industrial construction . Light construction generally refers to residential or small commercial buildings, while heavy construction usually relates to infrastructure like dams, highways, and bridges. Electrical construction is only a part of power station work and does not represent the overall project category. Hence, power stations are generally treated as industrial construction , making Option C the correct answer.
