SCOPE OF
WORK
The study will include
consideration of technical, economic, and social considerations
relative to retrofitting work. It will also include consideration
of innovative technologies to increase safety, reduce disruption
and maximize economies of the retrofitting process.
By formulating realistic solutions to real
buildings the project will provide valuable information to
help owners and authorities to decide on approaches for retrofitting,
not only for the subject buildings, but for other buildings
in Bakırköy, in Istanbul and throughout Turkey.
The project will also provide owners of the
369 buildings with an authoritative appraisal of the performance
of their buildings in earthquake, some practical options
for improving the performance, and a good indication of the
costs and disruption involved.
Because it is only a feasibility study it
will not involve any detailed design or implementation of
retrofitting work. That will be up to individual owners to
decide. However, the results of the project will provide
valuable information to the owners which will greatly help
them in their decisions.
Although possible mechanisms for funding
the retrofitting will be examined as part of the work, any
decisions to assist with the funding of retrofit will be
made by other authorities and are not part of the project.
Outline of
Work to be Undertaken
The principal elements of the work
are:
- Review the seismology of the region, particularly
as it affects Bakırkoy.
- Review and further investigate the properties
of foundation soils throughout Bakırköy to provide descriptions
of soil profiles for each building.
- Determine the details of construction
of each building, including concrete and steel strength
for use in structural analysis.
- Review the socio-demographic characteristics
of the owners/tenants and their evaluations on retrofitting,
through a survey questionnaire .
- Use the results of the seismology review,
soils properties and building information to carry out
structural analysis and the assessment of the performance
of each building in a major earthquake.
- Review and determine suitable structural
performance standards and criteria that provide an acceptable
level of life safety.
- Compare the assessment of each building
with the required standard of performance
- Based on the results of this assessment,
propose retrofitting solutions to improve the performance
of the buildings to acceptable standards. Social and economic
impacts of the retrofitting will be considered in determining
the options to be examined and in formulating overall recommendations.
- Analyse the performance of the buildings
on the basis that the proposed retrofitting has been done.
- Ensure that the retrofitted performance
would meet the required standards/criteria
- Estimate the costs and benefits of various
proposed retrofitting solutions, including the social,
environmental and economic impact.
- Prepare a report describing the current
status of each building and retrofit solutions considered.
Assess costs and benefits of the various options. (Note
“retrofit solutions” includes the option of demolition
and building anew.)
- Make recommendations to the Turkish Government
through the PIU and to the Bakirkoy Municipality on approaches
to retrofitting, indicating the key findings of the study.
- Throughout all of the phases of the project,
information on progress will be communicated to apartment
owners/tenants and building managers. It is proposed to
hold interactive meetings to listen to your comments and
to answer your questions.
