93.	When a major construction firm adopts Total Quality Management (TQM) principles
     to reduce rework and improve site efficiency, they implement the concept of ‘Kaizen’.
     In a construction setting, Kaizen is best demonstrated by

     (A) Firing the lowest-performing 10% of subcontractors at the end of every financial
         quarter to maintain high standards.

     (B) Relying entirely on end-of-project inspections by third-party auditors to identify and
         document non-conformities.

     (C) Reengineering the entire construction sequence from scratch to bypass standard
         operating procedures and accelerate the project schedule.

     (D) Empowering all levels of staff, from project managers to manual laborers, to suggest
         and implement continuous, incremental improvements in daily processes.

94.	In the maintenance of civil engineering infrastructure like bridges, highways, water
     treatment plants, etc., which of the following is considered a key performance indicator
     for asset reliability and service quality?

     (A) Cost Variance

     (B) Mean Time Between Failures

     (C) Earned Value

     (D) Return on Assets

95.   Which of the following statement(s) is/are true?

      (i) The acceptable limit for the safety and serviceability requirements before failure

          occurs is called a 'limit state'.

      (ii) The aim of design is to achieve acceptable probabilities that the structure will reach

          the ‘limit state’.

      (A) Only (i)

      (B) Only (ii)

      (C) Both (i) and (ii)

      (D) Neither (i) nor (ii)


96.	The following item consists of two statements, one labelled as 'Assertion (A)' and the

      other as 'Reason (R)'. Examine these two statements carefully and select the correct

      answer using the options given below.

      Assertion (A): A Town Planner or Civil Engineer is ethically justified in recommending

                        a highly cost-effective urban layout that fulfills all current environmental

                        regulations, even if they are aware it will significantly exacerbate

                        long-term urban heat island effects.

      Reason (R): An engineer’s primary fiduciary duty is to optimize project costs for the

                      client while ensuring strict compliance with existing baseline environmental

                      laws.

      (A) Both (A) and (R) are true and (R) is the correct explanation of (A).

      (B) Both (A) and (R) are true, but (R) is not the correct explanation of (A).

      (C) (A) is true, but (R) is false.

      (D) Both (A) and (R) are false.

97.	
    External whistleblowing (reporting an issue outside the organization to regulatory
     bodies or the public) is a severe step that breaks the standard confidentiality agreement
     between an engineer and their employer. Consider the following conditions under which
     an engineer is evaluating whether to blow the whistle on a contractor using substandard
     materials on a bridge project:
     (i) 
         The use of the substandard material poses a serious and considerable risk to
        public safety.
     (ii) The engineer has reported the issue to their immediate supervisor, but no corrective
         action was taken.
     (iii) The engineer has exhausted all internal escalation channels, including notifying the
          Board of Directors.
     (iv) The engineer has documented verifiable evidence that would convince a reasonable,
         impartial observer that a hazard exists.
	According to standard engineering ethics frameworks, which of the above conditions are
     necessary to make external whistleblowing ethically justified?
     (A) (i) and (ii)
     (B) (ii) and (iii)
     (C) (i), (ii) and (iv)
     (D) (i), (ii), (iii) and (iv)

98.	
    Which of the following statement(s) is/are true regarding the design principle
     ‘Form follows function’?
     (i) It states that the shape, appearance and structure of a building or object should be
        primarily based on its intended purpose or function.
     (ii) It dictates that design should prioritize aesthetics over utility
     (A) Only (i)
     (B) Only (ii)
     (C) Both (i) and (ii)
     (D) Neither (i) nor (ii)

100.	Which of the following statements best describes the design principle of ‘robustness’ in
      civil engineering structures?
      (A) The structure must remain stable under accidental events like fire, explosion or
           impact without disproportionate collapse
      (B) The structure should have the minimum possible deadweight to reduce foundation
           cost
      (C) The structure must be aesthetically pleasing while meeting functional requirements
      (D) The structure should be designed using only one material to ensure homogeneity
