GPSC Civil Engineering (Combine Exam) Paper Solution (03-05-26) – Page 4

31) In the ‘Bar Chart’ method of project scheduling, which of the following statements are known limitations that led to the development of CPM/PERT?

1. Bar charts explicitly show interdependencies (logical relationships) between activities.
2. Bar charts cannot identify the Critical Path – activities that if delayed will delay the project.
3. Bar charts cannot be updated easily when actual progress deviates from planned progress.
4. Bar charts cannot accommodate resource allocation and levelling calculations.

Which of the above statements correctly identify the limitations of bar charts?

1. 1 and 2 only
2. 1, 2 and 3 only
3. 2 and 4 only
4. 2, 3 and 4 only

32) For estimate preparation of government works, which of the following statements is incorrect?

1. Abstract of Estimate consolidates quantities from the measurement sheet and calculates amount (Qty Rate) for each item of work.
2. The Summary of Estimate adds contingencies such as supervision charges and departmental charges to the direct cost.
3. ‘Establishment charges’ are considered actual and not added in the Summary of Estimate.
4. ‘Work-charged establishment’ refers to staff engaged directly for a specific project, whose salary is charged to the project cost.

33) Which of the following components are included in the proposal for Technical Sanctions for government works?

1. Necessity and justification for the proposed work
2. Site plan, building plan and structural drawings (for building works)
3. Schedule of rates adopted with justification
4. Analysis of rates for non-schedule items

Which of the above statements are correct?

1. 1 and 3 only
2. 1, 2, 3 and 4
3. 2, 3 and 4 only
4. 1, 2 and 4 only

34) Which of the following statements is incorrect concept of ‘Lead’ in measurement of earthwork in public contracts?

1. ‘Lead’ refers to the horizontal distance over which excavated material is transported to the point of use or disposal.
2. As per specifications, the ‘free lead’ for earthwork is generally specified; beyond this, additional lead charges apply.
3. The ‘Lead statement’ is used to optimize earthwork by balancing cuts and fills to minimize total haulage cost.
4. ‘Lead’ also refers to the vertical height through which excavated material is raised.

35) Which of the following correctly states the ‘Sinking Fund Method’ for calculating depreciation?

1. A fixed annual sinking fund deposit (instalment) is made into a fund earning compound interest such that the accumulated amount equals the replacement cost minus scrap value at the end of the useful life.
2. Sinking Fund Instalment = (C – S) x r / [(1 + r)ⁿ – 1], where C = cost, S = scrap value, r = interest rate, n = life.
3. The Sinking Fund Method provides for replacement of the asset and accounts for time value of money.
4. The annual instalment in the Sinking Fund Method is more than in the Straight-Line Method, making it more conservative.

Which of the above statements are correct?

1. 1, 2 and 3 only
2. 1 and 2 only
3. 2 and 4 only
4. 1, 2, 3 and 4

36) Which of the following types does not correctly describe the ‘Specification Writing’ in civil engineering works?

1. ‘Prescriptive Specifications’ describe the materials, methods and workmanship in detail (how to build).
2. ‘Performance Specifications’ describe the required end result (what to achieve) without specifying how to achieve it.
3. ‘Proprietary Specifications’ name a specific manufacturer’s product; these are generally avoided in government works to ensure competitive bidding.
4. ‘Reference Specifications’ does not cite established codes/standards.

37) The carry-over factor in the Moment Distribution Method for a prismatic beam with far end fixed is

1. 0
2. 0.25
3. 1.0
4. 0.5

38) Plane stress condition exists in a structural element when

1. All three principal stresses are equal
2. Shear stresses are zero on all planes
3. One principal stress is zero (typically the out-of-plane stress)
4. Strains in one direction are zero

39) Which of the following statements is incorrect for ‘Cavity Wall Construction’?

1. Wall ties must be stainless steel or galvanized.
2. Wall ties must slope downward towards the outer leaf to prevent moisture transfer to the inner leaf.
3. Weep holes must be provided at the top of the cavity to drain any moisture that penetrates the cavity.
4. The thermal resistance (R-value) of a cavity wall is primarily from the still air and insulation in the cavity, not the masonry leaves.

40) ‘Functional Planning of Buildings’ involves several principles. Which of the following are correctly stated as per NBC 2016 requirements?

1. The minimum height of habitable rooms in residential buildings is 2.75 m (for tropical regions) as per NBC 2016.
2. The ‘Form Follows Function’ principle implies that building form/shape should be determined by its intended use and performance requirements.
3. As per NBC 2016, the minimum width of a corridor in a public building must be 0.5 m for single-loaded corridors.
4. The ‘Floor Area Ratio’ (FAR) or ‘Floor Space Index’ (FSI) is a zoning regulation that controls building bulk relative to the plot area.

Which of the above statements are correct?

1. 2 and 4 only
2. 1, 2 and 4 only
3. 1, 3 and 4 only
4. 1, 2, 3 and 4
