Key idea:
Correctly identifying the grade of a construction work at the very beginning ensures
the proper selection of contractors, standards and procedures throughout the project life cycle.
1. Legal basis
- Decree 06/2021/NĐ-CP on management of construction quality, construction and maintenance – official Government portal (Vietnamese): Decree 06/2021/NĐ-CP
- Circular 06/2021/TT-BXD and the consolidated document 06/VBHN-BXD on classification of construction works and guidance: 06/VBHN-BXD (Vietnamese)
2. Role of classification in project management
- Define required capacity of design, construction and supervision contractors.
- Determine competent authorities for appraisal, approval and acceptance.
- Choose the relevant set of technical standards and codes to be applied.
- Plan warranty, maintenance and safety inspection regimes.
3. Main criteria for grading construction works
- Height & number of storeys: higher and taller buildings usually belong to higher grades.
- Scale & floor area: total floor area, capacity and service scale.
- Structural scale & load-bearing capacity: large spans, heavy loads, complex structures.
- Functional importance & social impact: national, security-related or key infrastructure works.
- Type of works: civil, industrial, transport, infrastructure… each has specific criteria.
4. Summary of grades
- Special grade: extremely large and complex works with national-level importance.
- Grade I: large and important works requiring high-capacity contractors and advanced technology.
- Grade II: medium-scale works, common in civil, industrial and production facilities.
- Grade III: small works with simple technical requirements.
- Grade IV: very small works, basic and simple structures.
