Case Study
Sovannaphum Special Economic Zone – Quantity Surveying Support
Quantity surveying for a 204-hectare economic zone across 25 contract packages and 8 contractors.
Cost control, contract administration, and variation management were fragmented across 25 packages and 8 contractors. A structured commercial system was imposed, covering measurement, payment certification, and change control. Cost and contract data became traceable from first valuation to final account.
Executive Summary
A 204-hectare economic zone in Kandal Province required delivery of 25 contract packages across eight contractors. The client lacked a consistent approach to measurement, valuation, and payment certification, leading to unclear cost positions and delayed approvals. A centralized commercial structure standardized bill formats, valuation methods, and reporting. Interim and final accounts aligned to a single system, reducing disputes and establishing traceability.

The Challenge
The context, constraints, and risks shaping the project from the start.
The client needed to deliver core civil and infrastructure systems for a new economic zone, including roads, drainage, sewage networks, medium-voltage power distribution, street lighting, telecoms, water and reuse water networks, pumping stations, and treatment facilities. These works had to support early tenants while allowing future expansion.
Complexity
- 25 contract packages delivered by 8 contractors.
- Contractors and tenants from five nationalities requiring coordination.
- Different contract forms and documentation standards across packages.
- Material price instability requiring validation.
What Was at Stake
Without intervention: cost uncertainty, delayed certifications, and unclear liabilities.
How Chenla Stepped In
The targeted actions we took to resolve the core issues.
Engagement began post-award, inheriting a fragmented, pre-tendered package structure with limited commercial alignment.
Key Actions
- Structured all packages under a unified measurement and valuation approach.
- Standardized BOQ formats and measurement rules across contractors.
- Implemented a centralized tender process for supplementary works.
- Established monthly payment certification procedures with defined review and approval steps.
- Enforced variation control through formal instruction, tracking, and valuation records.
- Introduced centralized cost tracking.
- Reconciled final accounts with documented close-out records.
Framework in Action
The Canopy Framework™ principles most active on this project.
The cost control principles later formalized into the Canopy Framework can be seen here. Across 25 contract packages and 8 contractors, a centralized dashboard maintained a single source of truth for payment status and costs. Standardized bills of quantities and consistent measurement rules clarified cost positions and reduced disputes.
Continuous Visibility
“Silence is not neutral.”
Structure Before Clarity
“Define once, repeat reliably.”
