🛣 EPC Schedules Preparation Overview

For any EPC (Engineering, Procurement, and Construction) work, preparing accurate schedules is crucial. Incorrect schedules may lead to time extensions, cost variations, and contractual issues. This requires detailed data collection from the Detailed Project Report (DPR) and field investigations.

📌 Conclusion

A comprehensive Improvement Proposal is to be developed based on:
- Road, structures, junctions, utilities inventory
- Trial pits, geotechnical investigations
- Traffic & axle load survey
- Plan & Profile development
- Pavement and protection design

Only then can a detailed cost estimate and all required Schedules (A to H) be finalized.
