  • Periodical cost reporting
  • Actual vs planned cost comparison
  • Early warning for corrective actions
  • Monitoring cost changes
  • Forecasting final cost at completion
  • Revising estimates after authorized changes

Value Management (Pre-construction)

IS 15883 Part 1 — Information and Communication Management (Clause 6.7)

Key Concepts:

• Management Information System (MIS) is central for systematic data handling: collection, storage, sorting, analysis, and communication.
• MIS integrates information flow within and between agencies (client, architect, engineer, contractors).
• Information flows upward (progress, costs, quality) and decisions flow downward (policies, instructions).

MIS Objectives:

• Benchmark progress & costs (time schedules, cost estimates, material/labor schedules).
• Efficiently measure and verify project status (progress, cost, resources, quality).
• Convert operational data into actionable information.
• Deliver accurate reports at required detail levels and periodicities.
• Identify critical info for timely decision-making.
• Ensure timely communication to all management levels.

MIS Modules:

Integration with Project Management:

• MIS supports integration management (Clause 6.10) by coordinating actions across teams.
• Helps resolve conflicts due to delays or cost impacts by enabling timely rescheduling and communication.
