Project schedule crashing
The calculated project duration should be acceptable to the management. If the requirement is to complete
the project in lesser time, crashing of project schedule shall be conducted (see Annex A).
Project schedule crashing shall include following steps:
a) Decreasing estimated activity(ies) duration.
b) Modifying finish-start links to start-start or finish-finish links to have parallel activities.
c) Assessing increased resource requirement per day based on the actions of above two steps and reconciling modified resource schedules and time schedules for finishing the project by the modified optimum finish date.
6.1.9 Target Setting
The scheduled early and late dates for the activities and project milestones are the time based targets or baseline to be achieved by the project team. The resource scheduling data shall be the baseline resource requirement. At project execution stage, the actual progress of activities, actual resource usage and their productivity shall be compared with these targets to assess the project status.
6.1.10 Time Management Deliverables Project scheduling data shall be reported in the form of network diagrams and bar charts or Gantt charts. For each sub-project a separate network diagram or bar chart shall be prepared. To assess the overall project
schedule, these individual network diagrams and bar charts shall be linked together to form the master control schedule.
Line of balance (LOB) technique shall be used for scheduling repetitive projects, like similar buildings, very high rise buildings, etc; linear type segmented works like roads, airfields, tunnels, pipelines, etc; and such projects which are linked with each other for sharing resources or because of inter-project flow of information.
For preparation of network diagrams and bar charts, reference shall be made to in IS 14580 (Parts 1 and 2).
