Technical Supervision and Construction Quality Control
Supervision roles
Technical supervision (технический надзор) is the customer's control function over the contractor's compliance with project documentation, norms, and quality requirements. It is distinct from designer supervision, which checks conformity with design intent, and from state construction supervision, which enforces legality and safety.
Quality control instruments
Know the acceptance acts: hidden works act, intermediate acceptance, and final acceptance. Understand incoming control of materials (certificates, sampling), operational control during works, and acceptance control of completed elements. Laboratory testing supports these stages. Documentation must be complete, signed, and traceable.
Traps
- Confusing the authority to stop work: technical supervision can suspend works, but only state supervision can impose certain administrative measures.
- Assuming a hidden works act can be signed after covering - it must be signed before.
- Treating a material certificate as sufficient without incoming inspection.
- Forgetting that non-conformity requires a documented corrective action and re-inspection.
Worked example
A contractor covers reinforcement before the hidden works act is signed. The correct response is to require exposure, inspection, and a new act; the covered work cannot be accepted retroactively without documented evidence. If the contractor refuses, technical supervision suspends the next stage.
Rule of thumb
For each stage: check documentation, inspect, test if required, sign the act, then allow the next stage. No signature, no progress.
