Chapter-wise study notes for CPM & PERT covering network analysis, critical path, float calculations, crashing, and PERT probability.

CPM & PERT carries 2–4% weightage in GATE Civil and 5–8 questions in ESE Prelims Paper II. Critical path determination, total and free float calculations, PERT time estimates, and project crashing are standard question types.
CPM and PERT mock tests cover the complete project planning and scheduling syllabus for GATE Civil, ESE, and SSC JE — including network construction, critical path determination, float analysis, and probabilistic scheduling.
CPM and PERT for GATE Civil and ESE covers: project network diagrams (AOA and AON representation), activity-on-arrow networks, early start/finish and late start/finish calculations, total float and free float, critical path identification, time-cost trade-off (crashing), PERT — optimistic, pessimistic and most likely time estimates, expected time and variance, probability of project completion, resource scheduling, and Gantt charts.
CPM and PERT typically appear in GATE Civil Engineering with 1–3 questions (2–6 marks) per year, often as numerical answer type (NAT) questions requiring critical path or float calculation. While the weightage is modest, these questions are straightforward and scoring for well-prepared candidates.
In ESE Prelims Paper II (Civil Engineering), CPM and PERT is part of the construction engineering and project management section. ESE tests network diagram construction, critical path determination, float calculations, crashing of activities, and PERT probability analysis with greater numerical depth than GATE.
