Investigating the relationship between the recent investments on construction sector and some economic indicators of Turkey

Aydın, Aykut
Construction industry is believed to constitute a significant part of the economic development and there are quite noteworthy studies that analyze the relationship between construction industry investments and economic development. This study attempts to find out this causal relationship by using Toda and Yamamoto Augmented VAR model for Granger Non-causality. In addition, two separate models are used in order to detect the effects of specific construction activities such as residential, commercial and industrial by both public and private actors. The quarterly data are taken from Turkstat covering the period of 2000Q1-2013Q4 for model 1 and 2002Q1-2013Q4 for model 2. The results of the Wald tests of the first model shows that the total construction activities and GDP have bidirectional causal relationship both for public and private sectors. Also, a significant bidirectional causality has been found between public and private construction activities indicating the mutual interaction among different actors in the industry. However, the second model shows that these bidirectional causalities are not valid for specific construction types. According to the results of the Wald tests, all of the unidirectional relationships are proceeded from GDP to residential and commercial construction types of public sector, and residential and industrial construction activities by private actors. Nonetheless, an important bidirectional causality is detected between public residential construction activities and total employment.


Development of an IT-based tool for portfolio assessment and management for construction companies
Bilgin, Gözde; Dikmen Toker, İrem; Özorhon Orakçal, Beliz; Department of Civil Engineering (2019)
Development in the construction industry has leaded most of the construction companies to undertake more complex projects than before, which are generally executed concurrently. Therefore, project management routines of the companies may not support effective management of multi-projects. Project portfolio management approach has been suggested to meet requirements for coordinating multi-projects to meet strategic objectives under limited resources. Since project portfolio management requires a comprehensiv...
A Study on the price escalation system in public construction contracts in Turkey
Ercan, Muhammed; Dikmen Toker, İrem; Birgönül, Mustafa Talat; Department of Civil Engineering (2017)
The construction industry has a major role in the development of Turkish economy. The construction sector contributes 6-8 % of the gross domestic product of Turkey. At the same time, public investments comprise an important portion in the Turkish construction sector. Medium to large construction projects generally take over a year for completion and cost of materials and labor that are used as resources in construction projects often increase during implementation of construction projects. On the other hand...
Awareness of the Turkish construction industry towards industry 4.0 technologies and concepts
Ebrahimi, Shima; Dikmen Toker, İrem; Department of Civil Engineering (2019)
The Architecture, Engineering and Construction (AEC) industry is a well-known latecomer to the effectiveness proposed by embracing of Industry 4.0 technologies; while other sectors embrace digitization and Information Communication Technologies (ICT) as an innovative strategy for maintaining economic profit and efficiency. In spite of the potential benefits that proposed by Industry 4.0, this revolution was not able to gain enough attention in the construction industry. Therefore, this study took initial st...
A Hybrid genetic algorithm for multi mode resource constrained scheduling problem for large size projects
Gürel, Mustafa; Sönmez, Rifat; Department of Civil Engineering (2015)
Just like in all industries, some of the available resources, in order to finish a project on time, are constrained in construction industry. To be able to finish the project on time has high importance both for the contractor and for the owner. Project scheduling in which resources are limited for a particular time are called as resource constrained project scheduling problems (RCPSP) and occupies a significant place in construction management. Especially for large scale projects, little success has been a...
A statistical approach to lean construction implementations of construction companies in Turkey
Tezel, Bülent Algan; Nielsen, Yasemin; Department of Civil Engineering (2007)
One of the major change efforts for the construction industry is lean construction. This thesis analyzes the practices of the construction companies in Turkey from the lean construction perspective. Prior to the analysis in question, requisite information about change in the construction industry, lean thinking and lean construction will be presented. A questionnaire, based on a lean construction model, is used to survey the practices and gather the data for the analysis. Various statistical analysis method...
