Sustainable modernization method to increase energy performance of the public buildings using BIM techniques

This research represents sustainable building modernization model, which creates knowledge-based decision-making method for old public buildings refurbishment seeking to reach the best energy performance during the design stage. Despite the fast development and spreading standards, challenging research opportunities arise from process automation and BIM adaptation for existing buildings’ requirements. To aid decision-making, building simulation is widely used in the late design stages, but its application is still limited in the early stages in which design decisions have a major impact on final building performance. Building design is a multi-collaborator discipline, where architects influence design decisions, engineers, contractors, and building owners. Using digital systems and simulations this modernization method performs already expected building energy consumption in a quickest and economic way. This model is BIM-based where design and refurbishment are based on pre-built indicators, which allows assessing the building energy demand and eco-building parameters.

Evaluation of industrial parks efficiency for sustainable land use

Implementation of industrial parks had become a worldwide trend in recent decades to promote economic growth and reducing social differences among the regions. However, worldwide examples show that many poor decisions were made in the planning stage. As a result, we have a lot of inefficiently working, obsolescence and even abandoned parks. The purpose of this paper is to analyze the theoretical and applicable aspects of the rational planning of efficiency operating industrial parks. The authors presented the comparative analysis of two industrial parks in Tauragė region in term of efficiency. The results proved industrial parks demonstrate better performance (by the number of investors attracted to the park) and have to be developed near major cities to ensure the supply of labor force for developing industries.

The evaluation model of public buildings’ management efficiency with emphasis on social aspect

Today, state enterprises and municipalities are concerned about the non-effective use of public buildings. The optimization of their quantity, efficient management by ensuring rational use of resources and protecting the societal needs are complex tasks, therefore require the decisions, which based on the application of new knowledge. The article proposes a new knowledge-based management model, an original set of criteria for assessing the efficiency of public buildings use. The task of applying this original criteria system for assessing the efficiency of the use of cultural buildings of the exact municipality has been solved. With the help of the new model, municipalities will expand the possibilities for impartial decision-making and evaluate the efficiency of end-use of buildings with respect to social benefit criteria. The results are applicable to public sector organizations, especially for municipalities with particular problems associated with the management of a large number of public assets

Risks assessment model for the sustainable built environment of finishing construction works

Construction works are among the riskiest activities in Lithuania. To develop a sustainable environment at a construction site, risk factors must be first identified and then eliminated. Each case of a construction site, construction conditions and the project environment is unique. Thus, risks must be individually assessed considering distinguishing features of the construction works and the environmental conditions. Consequently, preconditions exist for the development of a new risk assessment model comprising risk assessment norms, the construction project and conditions of the construction processes. Expert evaluation and the TODIM method were used for the risk assessment of finishing works. Two construction sites were used to assess construction risks related to finishing works. The article presents risk assessment results based on the riskiest job at a construction site of finishing works as well as the line of priorities of the riskiest workplace.

The risk assessment model for construction projects including value creation and protection aspects

The article focuses on the identification and classification of key risk management criteria that represent the value creation and protection aspects for the construction industry. Nowadays, the assessment of the risk level of a construction project is especially important for the quality of construction projects as well as the growth of enterprises and the sector. To establish the most important criteria for the successful growth of the construction sector including value creation and protection aspects are developed.

A statistical approach for improvement of Best Worst Method (BWM)

This paper endeavors to measure the consistency of a decision-making tool, popularly known as Best Worst Method (BWM), which is one of the latest developments in multiple-criteria decision analysis (MCDA). BWM is finding a vast arra of applications in the literature. Several investigators have extended this tool. BWM measures the weight of decision-making criterion and is recognized as a subjective decision tool. The first step in this method is to find the best and worst criterion, while we suppose several experts are asked to present their evaluation over set of criteria. The aim is to measure how these judgments are consistent and reliable. So, we statistically (using χ2 distribution) add a pre-evaluation to experts’ opinion and analyze whether the agreement of experts’ opinions is satisfactory and group opinion is established. This action improves the quality of the decision-making process by incorporating the reliability evaluation of experts’ idea. This extension for BWM helps decision makers in facilitating and getting results that are more consistent for criteria evaluation. We present examples in sustainable construction and architecture project.

Criteria Evaluation for Contractor Selection in Cultural Heritage Projects Using Multiple Criteria Approach

The low bid is the most common applicable method in the contractor selection process, considering by only one dominant criterion. However, the lowest price criterion not allows selecting qualified, responsible, sophisticated, and knowledgeable contractor for cultural heritage projects. Moreover, the improper contractor selection may induce claims, litigation, and poor quality work, increased costs for project performance or management. Selection of appropriate contractor is very important for the success and excellent accomplishment of cultural heritage projects. This study presents criteria evaluation for contractor selection in cultural heritage projects. This paper provides reviews of contractor selection and proposed criteria evaluation, and determines the criteria of culture heritage contractor selection. This study applies the multiple criteria approach: AHP, PROMETHEE and EDAS approaches.

The analysis of Web technologies for BIM model processing

Web based BIM platforms are powerful tools for the architects and constructors therefore there exists big amount of such projects around the globe. Each of them has own advantages and disadvantages therefore it is important to understand which platform brings more benefits for the users in relation to the BIM model processing and project management. For this purposes Web based BIM systems need to be analysed and compared by their tools and opportunities. This paper is presenting the results of such comparison in condition of WebBIM platform development with the purpose of better understanding of the further development way.

Implementing BIM for industrial and heritage building conversion

From systemic perspective reconstruction and restoration of industrial buildings are similar to historical and cultural heritage buildings. The maintenance and reuse of these buildings becoming more and more important research area worldwide. This importance must increase the information management demand but however, the most advanced digital technologies are rarely used. Use of 3D modelling technologies or whole building information modelling (BIM) methodology can help to save digital information of historic buildings is a significant effort to preserve the heritage and retain its most valuable features.

Integration of LEAN Last Planner System in construction processes

Globally, the efficiency of the construction sector has declined around the world over the past 30 years. The main principles aimed at the improvement of the situation are based on lean construction. The concept of lean construction can be effectively used in the strategic process to improve waste reduction as well as cost and time efficiency, which results in positive outcomes such as environmental protection, economy and time-saving. Lean construction practices help to achieve significant benefits. However, many organisations still find it difficult to successfully and correctly integrate lean concepts. The research literature indicates that the construction industry has encountered poor implementation and integration of these concepts. Lean construction has eight main techniques for increasing productivity in implementing customer requirements in the construction industry. Having in mind that lean is the key requirement for gaining construction productivity, this paper provides the basic fundamental knowledge of lean construction. Also, it shows how to get the most effective results by applying the Last Planner System technique. The described case study demonstrates the integration of the Last Planner System technique into the project.
