Assessment of Buildings Redevelopment Possibilities using MCDM and BIM Techniques

The paper deals with abandoned former industrial buildings problem and buildings’ redevelopment possibilities with emphasis on sustainable development. A complex decision-making model for redevelopment of abandoned buildings, combining Building Information Modelling (BIM) and Multiple Criteria Decision Making (MCDM) techniques, is proposed. A case study of a former measurement equipment factory is presented. Ranking of possible redevelopment alternatives of the building using Weighted Aggregated Sum Product Assessment method with grey attributes scores (WASPAS-G) is proposed and the most rational projects are selected. While BIM techniques supports an effective selection process and allows implementation of full lifetime management strategy of a project and then of a real object.12th international conference “Modern Building Materials, Structures and Techniques” (MBMST 2016

THE IMPLEMENTATION OF CORPORATE SOCIAL RESPONSIBILITY INITIATIVE IN LITHUANIAN CONSTRUCTION SECTOR: SITUATION ANALYSIS

The article analyzes the concept of corporate social responsibility, its assessment methods, indicators and guidelines on standards. This work also presents the analysis of Lithuanian construction sector, examines the largest companies in this area, their possibility to develop the corporate social responsibility initiative, as well as the main difficulties in implementing the principles of social responsibility. The results show that in Lithuanian construction sector the high– income companies and companies that compete in the market over 15 years do not fully use the possibility of the development of global corporate social responsibility initiative.The article analyzes the concept of corporate social responsibility, its assessment methods, indicators and guidelines on standards.

Analysis of problems, consequences and solutions for BIM application in reconstruction projects

The main aim of analysis presented in this paper is based on the complex evaluation of Building Information Modelling (BIM) application and decision support in reconstruction projects. The reconstruction projects face the high level uncertainty during implementation mostly due inappropriate information management, insufficient quality control and low competence of participants. The application of advanced Computer-Aided tools such as BIM uses both with advanced Information and Communication Technologies (ICT) can be the way to solve the problems of reconstruction projects. The fourteen reconstruction projects have been analysed and the list of thirteen main problems has been identi­fied. The pair wise judgment of problems has been made based on in the expert survey using the Analytic Hierarchy Pro­cess (AHP) method. The occurrence, influence to project and significance of the problems have been calculated and were prioritised according to the importance and consequences. After the complex analysis of problems, it is suggested to use combined list of solutions of the BIM tool application in reconstruction projects to support decision making process

Ranking of Heritage Building Conversion Alternatives by Applying BIM and MCDM: A Case of Sapieha Palace in Vilnius

A balance (symmetry) between socio-cultural and socio-economic benefits as a part of the economic, social, and cultural development policy of each city and country should be assured when converting built heritage. To anticipate building conversion priorities and opportunities, modern technologies can be employed. However, currently the activity of reconstruction of heritage buildings is part of the construction domain wherein modern digital technologies have been the least ever applied. Therefore, photogrammetry and the 3D modeling of existing heritage buildings was suggested. A case study of Sapieha Palace, built in the Baroque style in 1689–1691 in Vilnius, Lithuania was explored in this research. The applied technologies and software (Agisoft Photoscan, Autodesk ReCap and Autodesk Revit) allowed for the creation of a high quality and accurate model involving both the textured exterior of the building and the interior layout. In addition, the valuable features of a building were identified and marked in a three-dimensional digital model. Based on the model, the authors formulated possible conversion alternatives of the building and identified the associated decision-making criteria, as well as determined their relative significance by an expert survey method. The authors suggested the application of the multiple criteria decision making (MCDM) method under uncertainty, namely the rough weighted aggregated sum product assessment (WASPAS), for ranking alternatives according to multiple criteria. Therefore, the suggested integration of modern digital technologies and decision-making models helps to assure the rational conversion decision of built cultural heritage based on high accuracy data as well as contributing to the sustainable development of engineering processes

Procurement with BIM: Lithuanian situation analysis and further development / Viešieji pirkimai su BIM: Lietuvos situacijos analizė ir perspektyvos

This article deals with the role and importance of procurement in the context of Lithuanian construction, and distinguishes the main weaknesses of the public procurement. The implementation of BIM and MCDM technologies during public tendering is described. The foreign good practice is analyzed, where BIM and MCDM technology is used during organization of public tenders in the construction field. The possibilities of applying the building information model are examined throughout the entire procurement process. The procurement organization model is proposed, based on MCDM and BIM technologies. It is found that implementation of BIM and MCDM technologies in the public tenders will be beneficial for both the state and the entire construction sector by reducing project uncertainties, risk expo-sure, shortening the project documentation review and, therefore, the construction time of the object.
