Cost Control and Earned Value Management
Cost Control and Earned Value Management (EVM) in the construction environment involve monitoring project expenses and performance to ensure projects remain within budget and on schedule. Cost control tracks actual spending against planned budgets, identifying variances early. EVM integrates cost, schedule, and scope to measure project progress objectively, allowing managers to forecast future performance and make informed decisions. Together, these practices help optimize resource allocation and minimize financial risks in construction projects.

💡 Key Takeaways
- Define Earned Value Management (EVM) and its role in cost control and project performance tracking.
- Compute PV, EV, and AC to assess current status against the baseline budget.
- Use variances and performance indices (CV, CPI, SV, SPI) to identify cost overruns and schedule delays.
- Forecast final project cost and completion date using EAC, ETC, and VAC, and plan corrective actions.
❓ Frequently Asked Questions
What is Earned Value Management and what are the main concepts PV, EV, and AC?
Earned Value Management (EVM) is a project performance technique that integrates scope, schedule, and cost. It uses Planned Value (PV), Earned Value (EV), and Actual Cost (AC) to measure performance against the plan.
What are the key EVM metrics (SV, CV, SPI, CPI) and what do they tell you?
SV = EV − PV indicates schedule variance; CV = EV − AC indicates cost variance. SPI = EV / PV and CPI = EV / AC indicate efficiency in schedule and cost.
How do you calculate Schedule Variance (SV) and Cost Variance (CV)?
SV = EV − PV; CV = EV − AC. Positive SV means ahead of schedule; positive CV means under budget.
What do SPI and CPI mean and how are they calculated?
SPI = EV / PV reflects schedule efficiency; CPI = EV / AC reflects cost efficiency. Values greater than 1 are favorable; less than 1 indicate problems.
What is Estimate at Completion (EAC) and which formulas are commonly used?
EAC predicts total project cost at completion. Common formulas: EAC = BAC / CPI; or EAC = AC + (BAC − EV) / CPI. Choose based on expected future performance.
