The inspection in order to provide certification may be conducted as from the date of commencement of the actual execution of building of the works or items of works to be certified, and should concentrate on those sections of the works and of the weight-bearing structure which, if impaired, could cause a disaster.

(a) Inspection of the surveying work and of the design work:

- Check of compliance with the provisions of law on capability of the entities which conducted the surveying work, design work and evaluation of the design, and of the application of technical standards and criteria.

case where the design was carried out in three steps) or of the design drawings for


4

execution of the building work (in a case where the design was carried out in one or two steps); and an assessment of the level of compliance of this data with the requirements stipulated in the technical standards and criteria used, in order to ensure the safe weight-bearing capacity of the construction works.

If during the course of the inspection there are any doubts about the survey results or the

results of calculations and measurements for the weight-bearing structure, then the inspection organization may suggest that the investor and the survey or design contractor clarify matters. In necessary cases, the inspection organization may suggest that the investor arrange a re-examination of the construction survey results and re-check the weight-bearing capacity of the structure.

(b) Inspection of conduct of the execution of building work:

of the structure relevant to weight-bearing capacity of the construction works.

If during the inspection process the inspection organization detects any factors which could influence the weight-bearing structure of the works, it shall request the investor and contractors to explain and clarify matters. In necessary cases the inspecting organization may suggest that the investor organize re-verification of quality or conduct its own re-testing, observation and measurements.

provisions of law on quality control [and] satisfy the requirements for ensuring safe weight-bearing capacity of the construction works.


5

- The data from observation and measurements and the external appearance of the structure reflect the normal condition of a weight-bearing structure.

- The results of any re-examination or reinvestigation ensure that the structure is of

adequate weight-bearing capacity.

The investor shall send one copy of the certificate, together with the report on results of the inspection, and together with the minutes of check and acceptance on completion of the certified works or items or works to the local State administrative body for construction, for the latter to check and administer.
