Abstract

After the Law No. 6306 on the
Transformation of Areas Under Disaster Risk (Law on Urban Transformation) has
entered into force, the buildings which have been damaged by the earthquakes
and completed its economic life can be reconstructed.  In case that the building is found to be
under the risk following the risk assessment to be carried out by the
institutions and organizations, licensed by the Ministry of Environment and
Urbanization (MEU), upon request of the owner/ owners of the property, the
building can be demolished. The resolution to be taken by at least two-thirds
majority of stakeholders will be valid for the selection of the contracting
firm for construction of new building after its demolition. We encounter with
the selection of the contracting firm as a problem of multi-criteria decision
making (MCDM).

The purpose of this study is to select
the contracting firm, which will construct the new building in the place of the
building under the risk that has been demolished under the urban
transformation, by using SWARA-based Gray Relationship Analysis method. In the
sample application; a-5-storey building with 10 houses was found to be the risk
building and MEU decided to demolish that building. The stakeholders of land
determined the criteria on the selection of the contracting firm to construct
the new building following the demolition of the building and alternative
contracting firms by utilizing the support of experts. The weighting of the
criteria was performed by using SWARA method and the alternative contracting
firms were assessed by Gray Relationship Analysis method. Thus, the contracting
firm providing maximum benefits and yield was selected within the scope of the
criteria set out by the stakeholders.

Kentsel Dönüşüm Kapsamında Müteahhit Firmanın SWARA – Gri İlişkisel Analiz Yöntemiyle Seçilmesi

Abstract

6306 sayılı Afet Riski Altındaki
Alanların Dönüştürülmesi Hakkında Kanunun (Kentsel Dönüşüm Kanunu - KDK)
yürürlüğe girmesinin ardından ekonomik ömrünü tamamlamış, depremlerde hasar
görmüş binalar yeniden inşa edilebilmektedir. Çevre ve Şehircilik Bakanlığı
(ÇŞB) tarafından lisanslandırılan kurum ve kuruluşlara mülk sahibi / sahipleri
tarafından yaptırılacak risk tespitinin ardından, binanın riskli olması
durumunda bina yıkımına gidilmektedir. Yıkım sonrası yeni bina inşası için
müteahhit firmanın seçiminde paydaşların en az üçte iki çoğunlukla alacakları
karar geçerli olmaktadır. Müteahhit firmanın seçim işlemi ise, çok kriterli
karar verme (ÇKKV) problemi olarak karşımıza çıkmaktadır.

Bu çalışmada amaç, kentsel dönüşüm kapsamında
yıkımı gerçekleştirilen riskli bina yerine, yeni binayı inşa edecek müteahhit
firmanın SWARA temelli Gri İlişkisel Analiz yöntemiyle seçilmesidir. Örnek
uygulamada, 5 katlı ve 10 daireli bir binanın riskli yapı olduğu tespit
edilerek, ÇŞB tarafından yıkılmasına karar verilmiştir. Arsa paydaşları
tarafından, yıkım sonrası yeni binayı inşa edecek müteahhit firmanın seçimi
için kriterler belirlenmiş ve alternatif müteahhitlerin seçiminde ise uzman
desteğinden faydalanılmıştır. Kriterlerin ağırlıklandırılması SWARA yöntemiyle
yapılmış, alternatif müteahhitler ise Gri İlişkisel Analiz yöntemiyle
değerlendirilmiştir. Böylece, paydaşların kendi belirledikleri kriterler
çerçevesinde, maksimum fayda ve getiriyi sağlayan müteahhit firma seçilmiştir.
