A study conducted to reduce construction waste generation in Turkey

Waste occurs within the lifecycle of buildings, during the construction, modification and demolition phases. These construction wastes become serious environmental problems in many countries and in Turkey. However, no net data regarding the amount of construction wastes exist in Turkey. During its period of usage, frequent interior modifications are made for various reasons, particularly true for residences in Turkey, thus generating construction wastes. The primary environmental target regarding this subject should be the prevention and reduction of construction waste generation. The aim of this study is to provide suggestions regarding the prevention/reduction of waste generated due to modifications done for various purposes in residences in Turkey. To this end, a survey of homeowners in Istanbul was conducted to determine the nature and purpose of modification work done in residences. In order to come up with solutions towards reducing the construction waste generation, it is vital that these reasons are known. In light of the causes determined, suggestions for solving the problems have been developed.

Artificial neural network cost flow risk assessment model

Previous attempts have been made to model cash flow forecast at the tender stage using net cash flow, value flow and cost flow approaches. Despite these efforts, significant variations between the actual and modelled forecasts were still observable. The main cause identified is the issue of risk inherent in construction. Using the cost flow approach, a model is developed to assess the impacts of risk occurring during the construction stage on the initial forecast cost flow. A questionnaire survey and case study approach were employed. As a first step, a questionnaire survey was administered to UK construction contractors to determine the significant risk factors impacting on their cost flow forecast. Using mean ranking analysis, the survey yielded 11 significant risk factors. The second stage of data collection involves the collection of forecast and actual cost flow data from case study projects to establish their variations at predetermined time periods. Using the significant risk factors identified in the first phase, relevant construction professionals who worked on the case study projects were requested to score the extent of risk occurrence that resulted in the observed variations. A combination of these two sets of data was used to model the impact of risk on cost flow forecast using an artificial neural network back propagation algorithm. The model enables a contractor to predict the likely changes to a cost flow profile due to risks occurring in the construction stage.

Mediation Model for Improving Cost Factors That Affect Performance of Small-Scale Building Construction Contract Business in Nigeria: A PLS-SEM Approach

Performance of small-scale building construction contract business poses a challenge to the sustainable development of the construction industry, particularly in developing countries like Nigeria. Small-scale construction contract business plays an important role in the economic development of any nation. In Nigeria, small-scale construction contract business has a tremendous role in the development of rural areas. This study assesses the mediation effects of client support with advance payment on cost factors that affect performance of small-scale contract businesses in Nigeria. The study identified three factors that affect cost performance of construction projects in developing countries: cash flow problems, effects of fraudulent practices, and effects of the nature of construction environments. In total, 550 survey questionnaires were administered to stakeholders in the Nigerian construction industry. Stratified proportionate random sampling method was used for the selection of respondents and 387 questionnaires were returned, with 357 used in the analysis.     

Effect of host country and project conditions in international construction joint ventures

Joint ventures (JVs) have become popular because of their importance as a strategic alternative in global competition. International joint ventures (IJVs) are difficult to manage due to their complex structures involving more than two entities having different and competing objectives and strategies. Since each construction project is unique, project-specific factors are significant for the success of an IJV as well as the risks associated with the host country in which the IJV operates. In this study, the impact of host country conditions and project characteristics on IJV performance is investigated through a questionnaire survey. IJV performance is defined as a three-dimensional construct considering the performance of the project, the IJV partners, and the IJV organization itself. The results of the study suggest that project-related factors have a great impact on IJV performance. But they failed to provide evidence that IJV performance is affected by host country related risks.

A Typology Of The Urban Poor In Turkey

ABSTRACT: This paper discusses the results of a survey conducted in 1992 in Ankara, Turkey, to develop a typology of the urban poor. It draws on poverty culture conceptualization and an empirical study done in the US. The present study was designed to identify the cultural and psychological differences among the poor. It was found that there were three types among the urban poor: doers, accommodators, and losers. The emergence of these types is explained in the historical context of the modernization, urbanization, and market-oriented economic policies in Turkey. The authors discuss the social policy implications of the findings for Turkey.
