Study on Lean Construction Implementation in Palembang

This research investigates the implementation of lean construction and its benefits in construction projects in Palembang. A qualitative approach is applied through literature review and in-depth interviews with respondents experienced in the construction projects. The interview results indicate that the implementation of lean construction in Palembang is still limited, although it has the potential to reduce carbon emissions and improve efficiency. Additionally, it is found that further introduction to the concept of lean construction is highly necessary, especially among architects, to facilitate the decision-making for sustainable design. The development of awareness of lean construction to practitioners in the architecture, engineering, and construction (AEC) industry in Palembang is essential to support the realisation of sustainable development.

Identifying critical challenges to lean construction adoption

PurposeThis study aims to set out to identify and evaluate potential obstacles to successfully implementing lean construction (LC) as a result.Design/methodology/approachSeveral indicators were recognized as major obstacles following an exhaustive assessment of the literature and a multicriteria decision analysis based on the analytic hierarchy process (AHP) of information obtained from a questionnaire survey that was directed to practitioners in the Indian construction industry.FindingsThe results of this AHP model suggest that “Managerial” and “Inadequate resources” categories with a priority weight of “0.361” and “0.309” have the highest levels of influence, respectively, while “Inadequate knowledge” and “just in time (JIT)” categories with a priority weight of “0.053” and “0.034” have the lowest levels of influence, respectively.Research limitations/implicationsConstruction companies can use the study’s findings as a guide to determine whether they are ready to embrace LC, learn more about the components needed for implementation or investigate any challenges that may arise. These businesses can then create plans to promote the adoption and application of the lean philosophy.Originality/valueThe Indian construction industry may see great success with LC management initiatives. LC concepts have been adopted by many nations, but during the past 20 years, there has only appeared to be a limited amount of lean implementation in the Indian construction industry. It seems that several structural and cultural barriers are preventing its effective implementation. Organizations will not be able to determine what improvement efforts are required, where these efforts should be directed or which initiatives could provide the best outcomes if they are unaware of the elements that influence the effective implementation of LC.

Benefits and Difficulties of the Implementation of Lean Construction in the Public Sector: A Systematic Review

Lean philosophy has shown successful results in the manufacturing industry since the eighties regarding efficiency, reducing cost and errors. However, the philosophy originated in the private sector, where the work rules are defined by business owners within the framework of some regulation. In the public sector, however, the picture is different. The way of working and carrying out operations and projects is directly defined by regulation, where the owner’s role—as in the private world—is embodied by the entire political system. This article aims to take a comprehensive look at the academic literature on how Lean has been applied in the public sector (LIPS) from a bibliometric perspective and then delve deeper into the concept of lean construction in the public sector (LCPS) through a systematic review. The results give a complete picture of the research in LIPS, revealing that research directions focus on implementing Lean, how it works in the public sector and the human factors involved in its practice and digitalization. Moreover, the advantages and challenges of LCPS have been presented, where again, the human factor is the central concern of researchers.

However, the review also acknowledges the challenges associated with implementing lean construction in the construction industry, such as resistance to change, limited knowledge and understanding, and difficulties in assessing its impacts. In conclusion, this literature review concludes that lean construction has the potential to enhance time, cost, and resource management in construction projects, and proposes the need for further research to overcome the challenges and facilitate its adoption.

Ensuring Efficient Implementation of Lean Construction Projects Using Building Information Modeling

Modern economic dynamics makes it more expedient to introduce lean construction tools into the activities of all value chain participants in construction. The need to take into account digitalization processes in construction entail an increase in the urgency of the problem related to the integration of digital technologies into the concept of lean construction. Many studies have been devoted to the problems of integrating lean construction with building information modeling (BIM) tools, which have proved their effectiveness and substantiated obstacles to their active implementation. However, issues related to assessing the cost-effectiveness of integrating lean construction with BIM and other digital technologies (if companies refuse to introduce BIM), which allow for improving the interaction of investment and construction project participants, have not been actively studied. This article examines the effectiveness of using digital tools and technologies that will contribute to the development of lean construction and reduce the corresponding losses of investment and construction projects in the example of Russia. A literature review, interviews with experts aimed at summarizing the results, as well as practical calculations taken from the existing project, were used for the purposes of this study. The main losses at each stage of an investment and construction project arising from problems in the interaction of participants in Russian construction were identified, the effects of integrating lean construction with BIM and other digital technologies were determined, an algorithm for selecting digital technologies to be integrated with lean construction was developed. The methodology for calculating the effect of the implementation of tools and principles of lean–digital interaction technologies, as well as recommendations for the implementation of tools in construction practice, were discussed.

Lean-BIM Approach for Improving the Performance of a Construction Project in the Design Phase

Over the last decade, the construction industry has suffered from various issues affecting the planning processes, team management, and decision-making during the design phase. Today, the concepts of Lean construction and Building Information Modeling (BIM) overlap and bring solutions to all phases of a construction project. Numerous studies have shown that leveraging BIM data through Lean principles can significantly improve the overall management of a project. However, the literature is still limited to optimizing the design phase to anticipate any deviation before the start of the work. This article aims to provide an updated review of the interaction between BIM and Lean in the design phase. The study is based on a systematic review of 61 articles selected using the Systematic Literature Review (SLR) approach. The obtained results allowed for the analysis of different Lean methods and tools that interact with BIM. Digitizing these methods and using them together is necessary to facilitate their application in a construction project. Finally, our study provides recommendations for researchers and professionals by identifying future scientific challenges.

The Application of Lean Construction Concept in Multi-Storey Building Construction Project

Every construction project cannot be separated from various obstacles or failures. For this reason, it is necessary to improve planning using the lean construction method. The problem in this research is how to apply lean construction concepts, what factors can cause waste, and whether there are significant differences between the perceptions of contractors, supervisory consultants, and owners on the factors that cause waste to occur in fire station building construction. The purpose of this study was to analyze the application of lean construction and analyze the factors that cause waste and the differences between the perceptions of contractors, supervisory consultants, and owners. This study employs both quantitative and qualitative methods. Based on the analysis of observations made, the application of lean construction that was reviewed has started to be implemented, and there are some that have not been implemented properly, such as checking for safety, increasing visualization, and first run studies, so that it can cause waste. Descriptive analysis shows that only a small part of the waste factor with data interpretation intervals is found, namely waiting time for instructions. The results of one-way ANOVA analysis showed that there is no significant difference between the perceptions of contractors, supervisory consultants, and owners of the factors that cause waste.

Implementation of Elements of the Concept of Lean Construction in the Fire Protection of Steel Structures at Oil and Gas Facilities

The work is aimed at developing a procedure for applying the concept of lean construction to improve the technological process of applying fire protection coating on the steel structures of oil and gas facilities. The experience of implementing elements of the concept of lean construction in the activities of the organization of the oil and gas complex is presented. The developed procedure involves the use of elements of the concept of lean construction, such as value stream mapping, the “Spaghetti” diagram, and timekeeping elements of the technological process. For the example of an existing object of the oil and gas facility, the developed methodology for the implementation of the concept of lean construction is realized. The results of implementation showed that the output per worker increased by 33%, the process time for applying fire protection epoxy coating decreased by 35%, and the total distance of the route of workers in the process of applying the composition decreased by 19%. The practical significance of the results in this study consists of the possibility of using the developed procedure in the activities of construction organizations to improve technological processes.

Investigation of Lean Production Knowledge among Employees in Building Inspection Organizations

Currently, lean construction has become very important, with lean manufacturing, a philosophy of production that in the most basic sense refers to the elimination of waste and tries to eliminate anything that does not add value to the product or service, emerging as a Japanese business pattern. The aim of this study was to determine the lean production knowledge among employees in building inspection organizations. To measure the level of awareness in construction inspection institutions, which are the leading entities in the construction sector, and the level of awareness on this issue, a survey was conducted through face-to-face meetings with engineering employees residing in Adana province. The results were converted into datasets in the appropriate Microsoft Excel format. With these datasets, the reliability level of the survey was measured using the SPSS program, and the data were analyzed using WEKA software. The study used association rule learning, a data mining method. According to the results, the number of employees who knew the definition of lean production was less than half, at 47%, while the number of those who knew about the concept of lean construction was 44%. The results obtained according to three different class labels were statistically interpreted, and it was determined that the employees lacked knowledge and sufficient awareness about the subject.

A Fuzzy-AHP and House of Quality integrated approach for Lean Construction Concepts Assessment in Off-site Construction

Lean Construction (LC) combines theoretical research and industry best practices in an off-site industrialized construction environment that adopts Lean Manufacturing (LM) concepts and the know-how to reduce waste in the end-to-end lean construction process. Off-site construction industries strive to implement lean manufacturing theory and application to maximize the allocation of their resources, reduce construction waste, and optimize processes to be economically competitive. However, decision-makers usually encounter barriers while selecting the best lean tools for successful integration. Those barriers are organizational priorities, mass customization, process limitation, and improvement consensus. As a result, lean practitioners tend to implement tools such as Value Stream Mapping (VSM), Process Activity Mapping (PAM), Root Cause Diagram (RCD), Failure Mode Effect Analysis (FMEA), Pareto Analysis (PA) to analyze and propose improvements to a manufacturing process effectively. However, the construction industry lacks a tool that can assess the effectiveness of the lean construction concepts implementation. Thus, this paper proposes an innovative approach to select and evaluate the appropriate lean concepts implemented in an off-site industrialized factory. Firstly, the assessment matrix utilizes Fuzzy-AHP in a pairwise comparison to determine the relationships and calculate the correlations between lean concepts based on the designed hierarchy structure. Secondly, the House of Quality (HoQ) matrix will be integrated to prioritize the selection criteria based on the company's strategic requirements and customer requirements. Finally, the proposed multi-criteria multi-decision ranking matrix is able to prioritize the top lean concepts and demonstrate their combinational impact by eliminating participant's subjectivity, bias, and preferences. The proposed assessment matrix was implemented in an off-site panelized construction case study to prove its effectiveness and validity. The results presented the synergies between different lean concepts combinations and their importance in a lean construction environment.

The Academic Development Trajectories of the Lean Production Based on Main Path Analysis Method

Enterprises looking to be competitive are constantly looking for a continuous increase in productivity, quality, and level of services. With the development of the industry 4.0 concept, manufacturers are more confident about the new advantages of automation and systems integration. Lean management is a well-developed and empirically proven managerial strategy. Combining lean and industry 4.0 practices seems to be a necessary evolutionary step to further raise the level of operational excellence. This study applied the main path analysis method to explore the development trend of lean management in the academic field. First, this study adopted the Scopus database to collect relevant papers, then analyzed their overall development trajectory by using Main Path 437 software, and used the g-index and h-index to identify more influential journals. Next, this study clustered the papers with similar topics into several groups, and then used Wordle software to present the keywords of each group in a word cloud that serves as a reference for naming. Thus, the top five groups obtained are as follows: “Lean production concept and application”, “Lean Six Sigma concept and application”, “Lean system integration and application”, “Lean construction concept and application”, and “Lean healthcare concept and application”. Finally, this study provides explanations and conclusions on each group’s development trajectory, as well as research recommendations in the field of lean production. The findings can serve as guides for industry, government, and academia as they develop future lean production development strategies. This study utilized an integrated analysis approach to successfully and effectively depict the trajectory of lean production development and applications, identify future research and development directions, and generate technological forecasts.

Identifikasi Faktor Kritikal Pendukung dan Penghambat Implementasi Lean Construction pada Megaproyek di Indonesia

Qualitatively, according to the waste in the construction sector in Indonesia, it is quite large, namely 57% when compared to the manufacturing industry which has 26% waste, the inefficiency in megaprojects is caused, among others, by too many design changes, low work expertise, delays in decision making, coordination that is not good between the parties involved, weak planning and control, delays in material delivery, and inappropriate work methods. Lean construction concept is used to eliminate waste and maximize value for users or customers. In addition, he said that the framework is a step-by-step guide in the form of a suitable guide to facilitate the implementation of the lean construction concept because the lean construction concept is a process-based concept. The purpose of this study is to identify critical factors that support and hinder the implementation of the lean construction concept in mega projects in Indonesia. In this study, a systematic literature review was used to examine the supporting factors and inhibiting factors for the implementation of lean construction. After conducting a literature review, four main supporting factors were obtained, namely managerial, labor, organizational and external. The managerial sub-factors are management commitment and Leadership Management. In addition, it was also found that the barrier factors from the implementation of lean construction were managerial, workforce, company/project organization and external. The supporting sub-factors of managerial are management commitment, management leadership, Management is unable to change existing construction concepts, Lack of training for contractors and subcontractors, misconceptions about lean construction method

IDENTIFYING BARRIERS IN LEAN AND IMPLEMENTATION IN THE CONSTRUCTION INDUSTRY

Lean construction is an emerging topic nowadays and this attracted my interest towards researching into this area. Concepts of lean construction are explained in this paper and all the barriers that were discovered from previous year research papers were surveyed according to there rankings and then the ranking of barriers is shown accordingly as a result. I have also determined the cost and time that can be saved if lean construction was implemented.

System-theoretical Approach to Fundamental Limits of Controllability in Complex Organization Networks

Organisation is fundamentally based on elaborating the equilibrium of two contradicting forces. An increasing degree of separation of work leads to specialisation and therefore significant increase of productivity in terms of time and cost. This advantage is compensated for by the therewith rising effort required to define, shape and delegate the subtasks to the different players and have them well-informed, coordinated and motivated to successfully contribute to the overall project. The well-known and common approaches to optimize division of work are mainly based on strict hierarchical structures like work breakdown structures in order to perfectly identify work-packages and their respective interfaces. Control loops are then established maintaining the certainty to achieve the previously defined results of the subtasks so that they will perfectly fit and will be ready to flawlessly form the total product. However, this traditional approach presupposes perfectly defined stable and separable systems as well as perfectly operating controlling mechanisms. As soon as some imperfection of either of these is given, which can be safely assumed in reality, the method is bound to fail principally. With this paper, we propose a system-theoretical framework modelling in particular a local imperfect however controlled situation and providing the principal limits on a mathematical basis as well as allowing for means for a practical approach. Organisations are represented by slightly contradicting systems while interactions as well as controlling mechanisms are given by first and second order differential equations according to the Theory of Systems. The resulting long-term behavior of the model, optimally avoiding oscillating and probably escalating development, indicates the principal limits of controllability. We find that the concepts of Lean Construction mainly address exactly these requirements and therefore find their formal justification including some quantitative framework.

Lean Construction Concept Used to Develop Infrastructure Facilities for Tourism Clusters

The relevance of the article is conditioned on tourist infrastructure problems and underdevelopment when creating and developing territorial clusters, for which there is not enough research materials in the context of tourism cluster facilities construction, despite the fact that the issues of lean construction (LC) are widely covered. Based on the relevance, the main hypothesis of the study was determined. It consists of the fact that the use of lean construction can increase the efficiency of construction megaprojects in the field of tourism clusters. The objective of this study is to develop a mechanism for the development of tourism clusters based on the lean construction concept that will be aimed at increasing the efficiency of construction projects taking into account the accumulated world experience. Within the framework of the tasks set, the analysis of the lean construction methodological base was carried out, methodological recommendations aimed at increasing the efficiency of construction megaprojects of tourism clusters based on the lean construction concept were developed, a model for the implementation of lean construction in infrastructure projects of tourism clusters, as well as a checklist of the analysis technology were elaborated. The proposed methodological approach to the implementation of tourism cluster megaprojects based on the lean construction concept is the basis for organizing and planning development activities at the tactical and operational levels. To assess the effectiveness of lean construction tool introduction to implement infrastructure projects of tourism clusters, a comparative analysis was carried out and the construction time and lifecycle cost of a typical guest house were calculated without taking into account the lean construction methodology and after its introduction. The results obtained, namely, the duration of the project and costs at life cycle stages made it possible to conclude that the proposed methodological approach is effective.

Mechanisms for implementing Lean - technologies as an innovative approach in modeling the structure of the standard time determining for construction processes implementation

Recently, a significant number of scientists' works have been devoted to the application of the lean-production principles, in particular, the introduction of lean construction. Objective construction cost estimation is a key factor in construction projects. The article discusses the problems, significant losses, low productivity in construction companies and the possibilities of their elimination due to the use of the lean-construction management concept as an innovative approach in modeling the structure of the standard time determining for construction processes implementation in order to increase the company's competitiveness. The productivity of the construction industry worldwide has been falling for the past 40 years. Companies must use appropriate methods to reduce their losses and increase productivity levels so that they can stand in the rapidly changing competitive environment of the current business environment. One of the approaches to improving the situation is the use of "lean management" in the construction industry is the result of the desire of construction business owners to optimize costs and increase labor productivity, the efficiency of organizational and technological processes, and introduce lean- production in the construction industry. A huge number of scientists and construction professionals are trying to change the traditional organizational and technological form of construction production and add value to owners, while making real profits. As a result, lean manufacturing tools have emerged that have been successfully applied to simple and complex construction projects. Ukraine is very far behind in terms of the development level of innovative processes from many countries of the world. Outdated ENiR norms, which were developed without taking into account the Lean strategy, need to be finalized. Of course, the introduction of a lean manufacturing system is a topic for the near future. Thanks to this, it is possible to significantly reduce the cost overruns on projects, as well as the time of their implementation up to 30%, or even more. Therefore, future research objective should be the development of a new modern methodology for determining the standard time, which will take into account the criteria of lean technologies, as an innovative approach in modeling the structure and sequence of all operations of construction processes.

Lean construction – an effective management system in the construction industry

The paper discusses the possibilities and prospects of using methods and tools of lean construction to improve the arragement of the construction business in the Belgorod region. Lean construction is considered as a system of innovative methods of process management in construction. The use of this system is an effective tool for optimizing the results of work: the time and cost of work is reduced by constantly improving the quality of the final product. Exploring the methodology and tools of lean construction, we can identify four main areas of use: employee engagement, cost reduction, optimization of construction processes, and loss prevention. The paper presents the results of using the concept of lean construction in foreign countries, as well as methods and tools aimed at involving employees in lean production, reducing costs and preventing losses, optimization, automation and informatization of the production process at the level of strategic and operational management. The specificity of the choice of tools and methods of work performed at all levels of management for the construction industry is determined. The application of the concept of lean construction is justified, which allows organizations to increase their competitiveness and business efficiency.
