1. What does “quality” really mean in construction projects?
Quality is not just about good appearance, and it is not “based on experience” or “we will adjust later if needed”.
In construction projects, QUALITY = THE DEGREE OF CONFORMANCE of the product to:
- The approved design documents
- The applicable technical standards (TCVN, QCVN, Eurocode, ASTM, AWS…)
- The relevant legal and regulatory requirements
- The quality clauses of the contract with the Client
Quality does not appear by itself – it is managed, measured and controlled.

2. Legal and technical framework that governs quality
A Project Manager who does not understand standards and regulations cannot truly manage quality.
2.1. Laws and regulations
- The Construction Law and its amendments.
- Procurement and contract regulations for construction.
- Regulations on construction quality management (e.g., Decree 06/2021/ND-CP in Viet Nam).
2.2. Vietnamese codes and standards
- QCVN 16 – National technical regulation on products and goods of building materials.
- QCVN 09 – Energy efficiency of buildings.
- TCVN 4453 – Construction and acceptance of reinforced concrete structures.
- TCVN 5574 – Design of reinforced concrete structures.
- TCVN 93xx – Testing and inspection of concrete and structures.
2.3. International standards
- ISO 9001 – Quality management systems.
- ASTM, ACI – Concrete and material standards.
- AWS D1.1 – Welding standards.
- Eurocode – Widely used in bridge and steel structure design.
A product that does not conform to standards is a nonconforming product – even if it “looks good”. The Client and the Consultant have full rights to reject acceptance when standards are not met.
3. The “quality triangle”: Scope – Tolerance – Acceptance
To manage quality, a Project Manager must at least control three key elements:
| Element | Practical meaning |
|---|---|
| Scope | Exactly what must be done? Where does the work start and end? What is not included? |
| Tolerance | To what level is workmanship acceptable? How much deviation is allowed? Under which standard? |
| Acceptance | Who accepts the work, with what criteria, and with which documents? |
Tolerances are often the silent killer of construction projects: a structure that looks good but is off by 3 mm at a critical location may still need to be demolished.
4. Quality documentation – the “brain” of the project
Quality lives not only on site, but also in the documentation system. The Project Manager should ensure at least the following:
- Approved method statements for all major activities.
- Inspection and test plans (ITPs) / checklists for every task and trade.
- Site diaries with accurate records of manpower, equipment and conditions.
- Material test reports (concrete, rebar, finishing materials…).
- As-built drawings that reflect what has actually been constructed.
- Inspection and calibration records for equipment (cranes, hoists, key machinery).
No documents – no proof of quality. In disputes, people do not only look at the structure, they look at the documents to determine responsibility.
5. Quality control along the project life cycle
Quality is not something to “worry about at the end”. It must be managed throughout the whole project life cycle:
| Phase | Role of quality management |
|---|---|
| Initiation | Define quality requirements, applicable standards and success criteria. |
| Planning | Develop quality plans, ITPs, test plans and inspection methods. |
| Execution | Build according to approved methods and standards, record everything properly. |
| Monitoring & Controlling | Inspect, test, identify nonconformities and decide on corrective actions. |
| Closing | Hand over the full quality dossier, capture lessons learned for future projects. |
Quality is not just the job of the QC department. It is a mindset shared by the whole project team – from the Project Manager and Site Manager to every engineer and foreman on site.
6. Tolerances – the silent killer of projects
In many projects, failure does not come from a single huge mistake, but from small tolerances that are ignored every day:
- Reinforcement shifted 5–7 mm from the designed position.
- Slab levels off by 10 mm from the datum.
- Unevenness of walls, ceilings and floors exceeding the permitted limits.
- Stone and tile finishes not aligned, leading to visible “waves” and misalignment.
One inaccurate measurement can make the whole team pay the price. The later deviations are detected, the more expensive the corrections will be.
7. Case study: Demolishing the whole façade because of 1.5 mm
7.1 Background
A hotel project with a high-end granite façade. The installation crew did not use laser levels and precise measuring tools, relying mostly on eye judgement and manual measurements.
7.2 Accumulated deviation
Each vertical line of cladding deviated about 1.5 mm from the adjacent one. On the first floor, this was hardly visible. But by the fifth floor, the total misalignment exceeded 15 mm and became clearly noticeable.
7.3 Consequences
- The Client refused to accept the façade.
- The entire misaligned granite cladding had to be dismantled and redone.
- Material and labor losses reached several billion VND.
- The contractor’s reputation was seriously damaged.
7.4 Lessons learned
Small tolerances can cause huge consequences. If tolerances are not controlled from the start – using proper standards, tools and inspection procedures – then quality depends only on “luck”.
8. Quality KPIs for Project Managers
Some simple but very telling indicators of a PM’s quality management capability:
- % of work items accepted at first inspection (no rework, no repair).
- % of materials passing tests at first attempt.
- Number of defects detected internally before client inspection.
- Number of rework / demolition incidents per work package.
If these indicators are strong, the system is likely healthy. If they are weak, it means the PM is not truly in control of quality or the quality system has serious gaps.
9. INDUSVINA’s quality culture
At INDUSVINA, quality is not just a “contract requirement” – it is the professional honor of construction engineers and managers.
Our quality culture stands on four pillars:
- Standardization: everything has standards, procedures and templates.
- Technical evidence: decisions are backed by data, tests and records.
- No compromise on tolerances: if it is wrong, we fix it – no “let it slide for now”.
- No shortcuts: we prefer to redo the work properly rather than hand over something that only “looks good on the surface”.
Quality is not just for handover – it is so we can confidently face the law, the auditors and, above all, our own professional conscience.
10. Conclusion – Quality as the PM’s professional honor
A quality project does not come from promises, personal “experience” or the sentence “I’ve done this many times, don’t worry”.
It comes from:
- Standards – clear technical criteria.
- Control – inspection, testing and strict acceptance.
- Documentation – evidence of compliance.
- Tolerances – controlled from the beginning, not accumulated.
- Acceptance – transparent, documented and professional.
If a Project Manager cannot manage quality, the PM has failed – no matter how fast the schedule is.
