TL;DR: In this paper, the authors used the Last Planner® System to overcome the limitations of traditional method of construction and process wastes by the implementation of last planner® System in residential project.
Abstract: Recently, Government of India has decided vision of 100 smart cities in 2020, and for a better productivity (on time, within budget and promised quality of projects), construction industry should adopt new construction management technologies but due to the tendency to adopt new management technology and other more reasons almost 80% construction projects are either time overrun or cost overrun. This problem can be solved by the adoption of tools of lean construction in Indian construction sector. Last Planner® System is one of the most efficient tools of lean construction and with the use of this tool; process wastes and negative effect of traditional method can be mitigated. Thus, objective of this study is to overcome the limitations of traditional method of construction and process wastes by the implementation of Last Planner® System in residential project.

TL;DR: In this paper , the authors used a qualitative data collection and analysis approach to evaluate the current processes of participating SMEs against Liker's 14 management principles of TPS, and developed an improved framework based on the TPS to enhance the performance of SME construction businesses.
Abstract: PurposeSmall- and medium-sized enterprises (SMEs) within the construction sector are highly vulnerable to disruptions caused by political and economic decisions or even pandemics. This study evaluated the current operations of selected SMEs providing engineering design and consultancy services against Toyota Production System (TPS) lean tool. The purpose is to juxtapose SME operations and processes with TPS to ascertain the level of their operations conformity to the established TPS lean thinking tool.Design/methodology/approachThis study used a qualitative data collection and analysis approach to evaluate the current processes of participating SMEs against Liker's 14 management principles of TPS. The data collected were analysed using thematic analysis to identify patterns and themes that emerged from the qualitative data.FindingsThe analysis revealed that focus on short-term goals, immediate profit and duplication of effort resulting from insufficient collaboration is currently creating waste in participating SMEs' operations. Hence, the implementation of TPS was recommended as a lean tool and a framework based on TPS lean tool was developed for improving the operations of SMEs.Research limitations/implicationsThe study is limited to SMEs operating only as consultants providing project planning design within the construction industry. Data collection is limited to qualitative even though observations would improve the outcome of the study.Originality/valueThe study advances contemporary issues in promoting lean implementation in construction sector and developed an improved framework based on the TPS to enhance the performance of SME construction businesses.

TL;DR: In this paper, the authors developed a process and best practices to combine the benefits of LPS and location-based management system (LBMS) to achieve the lean goals of decreasing waste, increasing productivity and decreasing variability.
Abstract: Research Question: The Last Planner System (LPS) and Location-Based Management System (LBMS) both aim to achieve the lean goals of decreasing waste, increasing productivity and decreasing variability. Q1: How to best link these two systems together to achieve better project performance? Q2: can the LBMS control mechanisms be integrated with LPS? Q3: Can phase pull scheduling be integrated with LBMS? Purpose: The purpose of this research is to develop a process and best practices to combine the benefits of LPS and LBMS. Research Method: Skanska Finland has used LPS and LBMS together. Because the planning and controlling methods in different industries can vary, a series of workshops was conducted at a hospital project on the US West Coast, and three other US companies were interviewed, to discover the factors specific to industries where activity-based scheduling systems dominate. These three sources of information were combined to the latest case study results on the stand-alone use of LBMS and LPS. Findings: The paper proposes processes to integrate LPS and LBMS in pre-bid master scheduling, pull phase scheduling, look-ahead scheduling, and weekly planning. Limitations: The proposed processes need to be tested in practice. Implications: The hypotheses for future research are that after implementing the proposed process, H1: schedule conformance will improve, H2: project durations will shrink, H3: productivity will increase, and H4: cascading delay chains will show a decrease. Value for practitioners: General Contractors or Construction Managers can begin to use the proposed processes in order to decrease durations and increase productivity.

TL;DR: In this paper, the main characteristics of the construction industry compared to the manufacturing industry according to three levels: on-site production, one of a kind projects, and complexity were determined.
Abstract: The growing context of globalization permanently increases pressure on the construction companies to improve their performances in order to resist to the constraints of competitiveness in the international market. It has become ineluctable to look for introducing a new alternative capable of bringing creative improvement to the traditional production system. This paper will relate mainly to the most relevant management techniques in the construction industry, and more specifically, the lean construction concept. Initially, we will determine the main characteristics of the construction industry compared to the manufacturing industry according to three levels: on-site production, one of a kind projects, and complexity. Subsequently, we will focus our attention on the main sources of waste in the construction industry. Finally, a rigorous comparative study will be carried out to show the contribution of the lean construction tools in the promotion of traditional construction especially at the level of the following factors: Creating value and eliminating waste; Planning and mutual coordination; Site organization. Lean construction as Last Planner System (LPS), Value Stream Mapping (VSM), Just-in-Time philosophy, Visual management (VM) and 5S have shown a great ability to improve the traditional production system through waste reduction, encouraging people involvement, ensuring a pull flow production, and promotion of a continuous improvement philosophy.

TL;DR: In this paper, a literature survey about the challenges faced by construction professionals during the implementation and use of LPS at both organizational and project levels is presented. But, the authors focus on the use of the Last Planner™ System (LPS) 5 of production control.
Abstract: Plan unreliability is a critical problem in the construction industry. Since the industry is fragmented and every project is unique, schedule delay is a common phenomenon. Ballard and Howell proposed that shielding construction and stabilizing work flow is a solution to this problem. These two researchers, along with other lean construction scholars, developed the Last Planner™ System (LPS) 5 of Production Control through a series of experiments beginning in the early 1990‘s. LPS has become a popular tool among the lean construction community to stabilize work flow and make plans more reliable. However, LPS users and mentors report numerous challenges with implementation and use of this system. This paper discusses findings from a literature survey about the challenges faced by construction professionals during the implementation and use of LPS. The aim of this research effort was to identify the challenges faced by construction professionals during the implementation and use of LPS at both organizational and project levels.

TL;DR: In this article, the authors identify the main barriers to successful implementation of lean construction in the Indian construction sector and suggest some lean principles to overcome these barriers, based on the success of Lean Production in manufacturing and the development of Lean Construction in countries such as Brazil, Denmark and the USA.
Abstract: Lean construction emerged from attempts of transferring and applying the Japanese Lean production philosophy to the construction industry. Lean construction is a confluence of ideas including continuous improvement, flattened organization structure, efficient usage of resources, elimination of waste, and cooperative supply chain. Based on the success of Lean Production in manufacturing and the development of Lean Construction in countries such as Brazil, Denmark and the USA, the application of Lean Construction is currently debated in India. The aim of the study is identification of barriers to successful implementation of lean construction in the Indian construction sector. The data was collected by questionnaire survey of project managers of building construction organizations and senior consultants of architectural and project management firms.The data collected was then analyzed to rank the main barriers and lean principles are suggested to overcome these barriers Keywords—Lean construction; waste; barriers; management; project
