Infrastructure projects are complex, task-based endeavours; the reliability of project schedules is often low, as delays occur. As a result, the infrastructure sector is constantly searching for innovative practices that might improve project performance. This study aims to pursue one research question: what are the benefits and challenges to last planner system (LPS) implementation in Australia’s infrastructure industry? It addresses this question through an examination of two rail infrastructure projects in Victoria, Australia.

The state of Victoria in Australia provides an excellent context for this study. The study was set in one of the programme alliances which was contracted to carry out five level-crossing removal projects. This study uses a combination of qualitative and quantitative research techniques, including surveys, interviews and site visits. The authors collected 43 valid survey responses. Additionally, 19 participants from the alliance programme’s two projects (Projects A and B) took part in the interviews. Extensive empirical evidence has been triangulated to achieve the research goals.

The findings show through the questionnaire survey that the greatest benefits that digital LPS brings are primarily associated with process improvement and social benefits. The interview results acknowledged that the roll-out of digital LPS had a positive impact on schedules, cost, occupational health and safety (OHS) and quality performance. The research also noted a few challenges in the introduction of digital LPS. Overall, the finding presents strong evidence that the introduction of digital LPS has been a clear success in the case company.

This is the first piece of research to fill this major gap in the LPS literature by exploring the issue of digital LPS adoption in Australia’s infrastructure sector. This study has thus laid the foundation for future work on LPS research in the Australian context. The authors are optimistic that this exploratory work will generate interest across other alliances, and perhaps extend into Australia’s construction sector.

The purpose of this paper is to investigate the Last-Planner-System’s impact on project cultures in terms of partnering.

A case study was performed using multiple data gathering approaches. The project cultures of three projects not applying the Last-Planner-System were compared with three projects that apply the Last-Planner-System. In total, 30 participants were involved in the study. Semi-structured interviews were held and analysed by applying qualitative content analysis. Also, the “organizational culture assessment instrument”, which belongs to the “competing values framework”, was used by means of an online survey.

The Last-Planner-System leads to increased levels of mutual understanding and control about the tasks and issues of the other parties. This detailed overview leads towards a more distinguished evaluation of the trustworthiness of individuals. This does not necessarily lead to a partnering project culture.

The contribution to research is that higher levels of transparency and mutual understanding do not necessarily lead to a high level of trust. Rather, transparency could be seen as a controlling mechanism that leads to better-founded estimations about the trustworthiness of others in the project.

To deal with the present situation and recover after the COVID-19 pandemic, construction firms are required to recognise the trends in construction supply chain management (CSCM) for the upcoming years and determine the appropriate practices towards the trends for the improvement of construction activities in terms of strategy, tactic and operations. This paper aims to recognise key trends in CSCM and uses these trends as strategic criteria for the evaluation and prioritisation of lean construction (LC) tools at different project phases including design and architectural engineering, planning and control, on-site construction and safety management.

The integrated analytic hierarchy process–Delphi method is used to collect and analyse the data from construction experts to evaluate the importance levels of the CSCM trends and recommend the appropriate tools for LC practices to improve project performances.

Seven key CSCM trends are identified: lean supply chain management (SCM), supply chain (SC) integration, SC standardisation, SC problem-solving, SC information-sharing, SC flexibility and SC sustainability. Based on these trends, a set of prioritised lean tools are suggested for LC practices, in which “virtual design construction” (VDC) and “last planner system” are considered as the central tools. These two LC practices can be integrated with other effective tools to support the strategic, tactical and operational targets in construction supply chain (CSC) projects.

This study gives the managerial implications by developing an application framework of LC practices for CSC projects. The framework promotes “VDC” as a strategic tool for the phase of design and architectural engineering and considers “last planner system” as the central LC practice for the phase of project planning and control. The framework also focuses on the improvement of efficiency in construction operations by taking into account the aspects of on-site collaboration, problem-solving, improvement and safety.

Up to date, there is still a lack of researches in classifying and prioritising the significant LC tools for each project phase to deal with CSC issues in both breadth and depth. Thus, this study is performed to provide construction managers with the awareness of CSCM trends on which they can focus to have strategic criteria for selecting LC practices to improve CSC performances.

Megaprojects are typically very expensive public-centred projects that leave little space for any mismanagement or deficient planning, which could affect the project adversely. The Last Planner™ System (LPS) is a lean construction planning and control tool that functions to reduce waste and increase performance. Given the benefits, the application of the LPS in megaprojects is still scarce, especially in Malaysia. Hence, this study aims to compare the current production planning, monitoring and review practices in a megaproject with the LPS in order to explore the possibilities of adapting the LPS to the current practices.

This longitudinal case-based study has first explored the current practices implemented in an infrastructure megaproject, which is an urban rapid transit (URT) project, which was then compared to the standard LPS practices. The case study has adopted several research methods such as observation, interview and document review.

Findings from the study highlight that the current production planning, monitoring and review practices in the URT project mostly differs from the standard LPS practices with only slight similarities found in the major planning phases. The comparative study, which based on five reference points through master, phase, look-ahead, weekly work plan and measure, and learning has resulted in several key elements, representative of the different planning phases, such as collaborative programming, reverse planning, reliability, dependability and continuous learning.

This study provides an alternative perspective to rail planners, as well as other types of project planners in considering the use of the LPS to enhance the quality of planning, monitoring and review in projects. The framework that highlights the core values and key elements for the related planning phases enables project teams with no lean background to partially adapt their current practices to the LPS with minimal disruption.

This study first contributes to the body of knowledge, where limited study was found comparing and contrasting current production planning practices against the LPS, particularly in rail-based megaproject. The results from the comparison are the key elements representing each of the planning phases that was rooted back to the core values (teamwork, involvement and collaboration, communication and transparency, and continuous improvement) necessary to enhance the current practices.

Project management has neglected production. Its theory and techniques are devoted for the most part to the formation, award and administration of contracts. Production management has equally neglected projects. Developed in manufacturing, theories and techniques of managing production focus almost entirely on the task of making multiple copies of a single design. Management of project‐based production systems lies at the intersection of these two disciplines, is enormously important, and has been until recently almost entirely undeveloped. A new project delivery process is emerging in the architectural/engineering/construction (AEC) industry. Its first module is production control, dedicated to the management of work flow between specialists. A new production control system, termed the ‘Last Planner’ system, has been successfully applied both to construction and design phases of AEC projects. The paper presents a case study describing one of the first applications of Last Planner to design, which is considered to be essentially a value generating process.

Several studies have addressed the use of four-dimensional (4D) building information modeling (BIM) for construction management. However, the automation of the processes for generating 4D models and their integrated use with Location-Based Planning and the Last Planner® System is not well discussed. Therefore, this paper aims to develop a method for automating the generation and use of 4D BIM models integrated with Location-Based Planning and Last Planner® System supporting project control cycles.

The research strategy adopted was Design Science Research. The automated method for using the 4D models was developed and refined in two residential building projects in Brazil, along with 31 meetings and involving 11 direct users. The assessment of the proposed method focuses on four constructs: the impact of process automation, the impact on the identification and assessment of site progress and the planning process, ease of adoption and utility of the proposed method.

The results of this paper indicated increased adherence between planned and executed through an automated method for using the 4D models. The established routines enabled automating the link between the planning levels and the three-dimensional (3D) model, providing a more agile and updated data source and achieving 92.8% of user satisfaction regarding the deadline and frequency of delivery of the 4D model reports. Moreover, this study identified the relationships between the processes of the method proposed and Digital Models.

The primary scientific value achieved in this study is creating a method for automating processes and simplifying steps for the generation and use of 4D BIM models in the production planning and control cycles during the construction phase.

The purpose of this paper is to identify how the newly emerging UK practice of “collaborative planning” (CP) for construction project delivery aligns with the advocated principles of the global last planner system (LPS) of production planning and control.

A mixed, qualitative, exploratory approach was adopted for the study. This entailed qualitative data through three techniques, namely: semi-structured interviews, documents analysis, and structured observation. In total, 30 in-depth interviews were conducted over a 12 month period with lean construction consultants, clients, main contractors, and subcontractors drawn from the building, highways and infrastructure and rail sector. In all, 15 projects were visited where practices were observed.

The study reveals that the current practice of CP in the UK partially aligns with the LPS principles. Where practitioners have heard of the LPS they believe it to be the same practice as CP.

This study is limited to 30 interviews, observation of 15 projects and document analysis. The aim of the study is not to generalise the findings, however, since the study examined top construction companies and practitioners in the UK and the findings were consistent across the sample, some conclusions could be made. The study is also limited to examining the construction phase only, future studies should incorporate the design phase.

A clear identification of the elements of current practice compared to the components of the LPS provides a contribution to the future practice of project production planning and management in the construction industry.

The study highlights a continuing resistance to collaboration within the industry. This resistance is subtly embedded within implemented practices even though they are based on collaborative working for their success.

This is among the first studies in the UK that comprehensively examines and reports the application of LPS/CP practice in construction across the major construction sectors. Future studies could build on the findings from this work to develop an approach/methodology to improve the current practice.

The purpose of this paper is to evaluate the effectiveness of implementing the Last Planner System (LPS) to improve construction planning practice and enhance site management in the Saudi construction industry.

LPS was implemented in two large state-owned construction projects through an action research process. The data collection methods included interviews, observations and a survey questionnaire.

The findings identify benefits including improved construction planning, enhanced site management and better communication and coordination between the parties involved. The paper describes the critical success factors for LPS implementation. The paper also describes barriers to the realisation the full potential of LPS, including the involvement of many subcontractors and people's commitment and attitude to time.

The work reported in this paper is limited to two case studies.

The study has thus contributed to improving management practice and may aid the establishment of a basis for the development of further research in the area of lean construction. The research outcomes can inform practitioners of the opportunity to implement alternative management methods in construction, and give a good account of the opportunities and challenges. Beside the direct benefits to managerial practice, the study also contributed to practice by offering practical recommendation that can assist in the achievement of the full potential of lean and LPS in Saudi Arabia.

This is the first comprehensive academic study in the Saudi construction sector concerning the application of lean construction principles and techniques. The study has thus contributed to practice and developed a basis for the development of further research in the area of lean construction. It may help construction organisations to establish a new strategy and policies to improve their managerial practice. The outcomes of the case studies can be used as a reference for organisations seeking to improve their managerial practice.

Documented evidence supports the improvements resulting from the use of the Last Planner System® (LPS) as a lean construction technique; however, several barriers to the implementation of the technique have been identified. The purpose of this paper is to evaluate the implementation process of LPS by a project team that is transitioning from the traditional planning and control to LPS on a typical commercial project. The paper compares the adopted implementation process with that of the recommended best practices and identifies the overlaps and variances.

An in-depth case study was conducted to accomplish the specific objectives: document the process of LPS implementation in detail; identify the overlaps and variance from the recommended practices; and investigate the causes for variance from the recommended practices. The authors used direct observations, document investigations and semi-structured interviews with key project participants to gather data. Constant comparison and content analysis were used as data analysis method for this study.

The paper identified critical barriers to the implementation process of LPS in the case study project, which are supported by existing literature and are considered typical of project teams that are new adopters and transitioning to the implementation of LPS.

Based on a single case study, the outcomes may lack generalizability. However, similar findings of existing literature and evaluations by the project personnel substantiated the findings of the study.

The study attempted to conduct a systematic investigation on the implementation process of LPS, which is a less investigated topic. The paper draws attention to the major barriers experienced while adopting LPS in the case study project and suggested possible ways to address similar issues in the future. The barriers experienced by the case study project are typical of project teams who are new adopters and transitioning to the adoption of LPS, process and have the potential to be alleviated through the recommended practice implementation and process maintenance strategy.

The purpose of this paper is to prioritize the vital tools/techniques for the effective implementation of the last planner system (LPS) in the cross-cultural setting of a developing country, i.e. Gaza Strip. Besides, the potential benefits of implementing LPS are prioritized.

The significant techniques and likely benefits of LPS implementations were identified through comprehensive literature, followed by their verification through a pilot study. The quantitative data were collected using a questionnaire survey from 89 companies, operating in the Gaza Strip construction industry. The relative important index was calculated for prioritizing the significant tools/techniques (16) which support the effective LPS implementation, and highlighting the potential benefits (10) achieved through LPS implementation.

The results showed that the “use of visual devices to spread information in the construction site,” “attendance of key actors” and “look ahead plan” are the most important tools/techniques supporting LPS implementation. The top three potential benefits of implementing LPS include: “allows a better understanding of the program control,” “maximizes the co-operation and confidence among team members” and “allows the manager to better visualize the work program.” To prevent any waste in project time and to ensure the material supply and continuity of works, the study recommends advance supply and storage of demand materials, and early availability of the shop-drawings for acceptance by the superintendent.

The study’s findings are expected to guide the key construction stakeholders to prioritize their energies toward effective LPS implementation in the Gaza Strip.

Though this study pertains to Palestine, its methodology can be generalized in other countries and regions, having a similar work environment, after making necessary cultural adjustments.
