1. Preparation of Soil Survey and Geotechnical report.
2. Implementation of Site-Specific Earthquake Hazard Analyses (TBDY
(2018)-Chapter 2.4.1).
3. Definition of Earthquake Ground Motions in the Field of Time History
(TBDY (2018)-Chapter 2.5).
4. Site-Specific Soil Behavior Analyses (TBDY (2018)-Chapter 2.4.2 and
Chapter 16).
5. Preparing the preliminary structural design, and if required (if there is
ZD or ZE clas soil and piled foundation), Structure Pile Soil interaction
analyses (TBDY (2018)- Chapter 16.10).
6. Preparation of technical specifications for seismic isolators and
dampers, if any (main parameters, test conditions etc.).
7. Making the tender in accordance with the preliminary design.
8. Selection of the isolator manufacturer taking into account the
qualification conditions.
9. Selection of an isolator test center capable of performing tests in
accordance with the needs. Duration is also important if there is a busy
activity in isolator test centers.
10. Production of prototype isolator and damper, if any.
11. Realization of prototype tests of isolators and dampers.
12. Checking the structural design according to the test results.
Again for the first time in TBDY (2018) under the title “1.3 Design Supervision
and Control in Special Cases” it became mandatory to receive “design
supervision and controlling services from civil engineers with theoretical and
professional knowledge and experience in the relevant field, who will work at all
relevant design stages from the beginning of the project to the completion of
issues requiring special expertise in the evaluation and design processes related
to the implementation of the regulation . It is also obligatory to receive design
supervision and control services in designing the seismic isolation buildings
to be constructed according to TBDY (2018) Chapter 14, and this service
is rendered by persons who hold Design Supervision Expertise (TGUA-5)
certificate. TGUA-5 controls all the above steps as a whole and is responsible
for carrying out these processes in accordance with the regulatory rules
and engineering principles. Reviewing earthquake records that are scaled
according to the selected and site-specific earthquake spectrum, evaluating
the suitability of design criteria and approach, reviewing the prototype test
program and checking the test results, and evaluating the suitability of the
final isolator parameters and the final design are among the main tasks of
TGUA-5. In addition, it is necessary to provide services from persons holding
