4D-5D Integrated Control (Earned Value from Models)
4D-5D Integrated Control (Earned Value from Models) refers to the use of digital applications in construction to link project schedules (4D) and costs (5D) directly to Building Information Models (BIM). This integration enables real-time tracking of progress and budget by comparing planned versus actual performance, facilitating earned value analysis. The approach enhances decision-making, improves project transparency, and streamlines information flow for more effective construction management.

❓ Frequently Asked Questions
What is 4D-5D Integrated Control in project management?
An approach that links the 3D model with time (4D) and cost (5D) data to monitor performance and compute Earned Value metrics, enabling integrated control of schedule and budget.
How is Earned Value derived from models (Earned Value from Models)?
Earned Value (EV) represents the value of work actually completed. In a 4D/5D model, progress from the model (completed tasks, quantities) maps to planned value (PV) and actual cost (AC) to compute EV and compare against PV for schedule and cost performance.
What are the main benefits of 4D-5D Integrated Control?
Improved visibility into progress and cost, earlier detection of overruns, better forecasting, and stronger collaboration due to automated, model-based EV metrics.
What is required to implement 4D-5D Integrated Control?
An up-to-date 3D/4D/5D model with defined cost codes, a baseline schedule, data integration between progress and cost systems, and a dashboard to track Earned Value metrics.
