Abstract

The aim of the article is to analyze existing foreign experiences presented in the literature in the field of estimating demolition waste and their applicability in Poland condition. Using the case study method for more than a dozen objects, the authors prove the necessity to verify the suitability of the proposed models in relation to regional conditions (e.g. climatic conditions, local technologies, etc.). The amount of concrete waste from demolition of objects made in the analyzed technology is characterized by a low coefficient of variation, especially in the case of public facilities and is only 10%. However, in the case of residential buildings, the volatility was 16,7%. The calculated average index of concrete waste was compared with the two literature models. The results obtained differ from the values obtained from the models. Based on an analysis of the advantages and disadvantages of the selected models and their assumptions, a proposal has been formulated for the development of an effective tool for estimating demolition waste taking into account regional specific conditions together with the concept of sustainable construction. The focus was on waste from demolition of concrete objects.

Abstract

The aim of this study is to identify the constraints that affect the effective usage of the site waste management plan (SWMP). A substantial review of the literature was carried out to identify the constraining factors that affect the site waste management plan tool. Questionnaires were administered based on a five-point Likert scale and the data were assessed and analyzed using IBM SPSS version 28. The outcome showed that the knowledge of the SWMP is still very low in the Polish construction sector. Only 6% have a written SWMP while 16% have used this tool in their previous project. Hence, the need for the increased awareness of the SWMP as one of the waste management strategies. The lack of adequate monitoring and control of the SWMP, lack of awareness, time required for the preparation of the tool were identified as the top constraints. The solutions identified include; increased level of awareness and education, the inclusion of the SWMPas part of the contract documentation requirement, adequate training of the site personnel, and presence of waste manager.
