Reinforcement Works and QC - EOQ

REINFORCEMENT WORKS AND QUALITY CONTROL WHICH WERE
PERFORMED IN 24 SCHOOLS IN ĐSTANBUL IN THE SCOPE OF THE ĐSMEP
PROJECT
Due to the usage of the construction equipment which are not in compliance with the
applicable standards, the unqualified operators violating the technical operation standards, the
insufficiency of the audits in time and completeness; the construction of the concrete
structures cause losses of life and property just as in 1998 Ceyhan Earthquake and 1999 Đzmit
Earthquake.
As a consequence of the loss adjustment works which were performed following the main
earthquakes experienced in Turkey; it is detected that large scale damages have occurred also
in the public buildings.
Therefore, building reinforcement projects have been implemented in order to make the
educational buildings throughout Turkey to become more safe against the earthquakes.
In this scope; the building reinforcement works of 24 schools with 80.000 m 2 are in ĐSMEP
project have been performed by Ilgaz Đnşaat by the year 2009. .
In the reinforcement projects for the educational buildings;
a- The compliance of the iron equipment, epoxy resin adhesive and repair ingredients,
concrete chemicals which improve adherence between new and old concrete,
aggregate which is used for producing concrete, cement, concrete chemical and
concrete mix water to the applicable standards are detected through the laboratory
tests and these materials were started to be used.
b- Each phase of application is controlled by quality control audits and the performance
of the productions pursuant to the standard and specification criteria is ensured.
c- In the scope of reinforcement; C30 norm automatic settlement concrete is used and the
concrete pressure resistance results are controlled by assessment pursuant to the ACI
criteria.
d- After completing the reinforcement works and following the completion of the
restoration works required for the usage of these structures as educational buildings;
these buildings are started to be used in the educational services.
In the scope of the performed reinforcement works;
• 800 tons of iron in various sizes pursuant to the TS 708; and
