Introduction

Core Value and Technological Evolution of Standards

This guideline systematically constructs a dual-track compilation system for the final settlement of hydropower projects for the first time: it retains the contract execution perspective of the execution budget, and realizes government supervision benchmarking through the approval budget regression. Compared with the 2019 version of the final settlement standard, 12 key technical specifications have been added, including dynamic price difference calculation and deduction of materials supplied by Party A.

Analysis of key term definitions

Terms	Definition points	Application scenarios
Execution budget	Dynamic investment control document based on the contract system	Internal cost control of the construction unit
Approval budget	Static investment benchmark approved by the government	Industry supervision and post-evaluation
Budget regression	Restoring actual investment to the approved framework	Investment deviation analysis

---

Comparative analysis of preparation frameworks

Expression form of execution budget estimate

Adopt the Lot decomposition method:

• The hub project is divided into 6 types of lots (early construction/main building/equipment procurement, etc.)
• The interest during the construction period is divided according to the actual amount incurred
• The reserved ratio of the final project is ≤3% of the total investment

Expression form of approved budget estimate

Adopt the Project aggregation method:

• Construction auxiliary projects are listed separately
• Independent expenses are divided into 4 sub-items
• Value-added tax is listed separately

Innovative preparation requirements

The standard clarifies for the first time:

1. The settled bidding sections adopt the closed audit principle (6.2.1.2)
2. The unsettled bidding sections implement the dual-track pricing (contract price + forecast price)
3. Insurance compensation offset mechanism (6.2.5)

---

Implementation suggestions

Solutions to common problems are proposed:

Problem type	Handling suggestions
Price difference of materials supplied by Party A	Deducted from the supplier's bidding section, not counted from the user's bidding section
Estimate regression deviation	Balanced through independent expense items
Finishing works exceed the limit	Special explanation and reporting are required
