GATE 2023 AR — Architecture – Question 46

Project Management and Professional Practice · Construction project management techniques e.g. PERT, CPM · 2 marks · Numerical answer

A project starts 29 January with no holidays. Activity A:96 m³, 8 workers, 3 m³/worker-day; B:252 m³, 7 workers, 4 m³/worker-day; C:275 m³, 5 workers, 5 m³/worker-day, after both A and B; D:126 m³, 6 workers, 3 m³/worker-day, after B. In February, on which date does the project finish? Give the day number.

Show answer and explanation

Correct answer: 17 to 17

Explanation

Durations are A=96/(8×3)=4 days, B=252/(7×4)=9, C=275/(5×5)=11 and D=126/(6×3)=7. C waits for B and finishes at 9+11=20 days; D finishes at 16. Counting 29 January as workday 1, day 20 is 17 February. Enter 17, not the duration 20.
