Purpose The purpose of this paper is to present a new method for project tracking and control of integrated offsite and onsite activities in modular construction considering practical characteristics associated with this type of construction. Design/methodology/approach The design embraces building information modelling and integrates last planner system (LPS), linear scheduling method (LSM) and critical chain project management (CCPM) to develop tracking and control procedures for modular construction projects. The developed method accounts for constraints of resources continuity and uncertainties associated with activity duration. Features of proposed method are illustrated in a case example for tracking and control of modular projects. Findings Comparison between developed schedule and Monte Carlo simulation showed that baseline duration generated from simulation exceeds that produced by developed method by 12% and 10% for schedules with 50% and 90% confidence level, respectively. These percentages decrease based on interventions of members of project team in the LPS sessions. The case example results indicate that project is delayed 5% and experienced cost overrun of 2.5%. Originality/value Developed method integrated LPS, LSM and CCPM while using metrics for reliability assessment of linear schedules, namely, critical percent plan complete (PPCcr) and buffer index (BI). PPCcr and BI measure percentage of plan completion for critical activities and buffer consumption, respectively. The developed method provides a systematic procedure for forecasting look-ahead schedules using forecasting correction factor Δt and a newly developed tracking and control procedure that uses PPCcr and BI. Quantitative cost analysis is also provided to forecast and monitor project costs to prove the robustness of proposed framework.

Resumo A abordagem de planejamento e controle da produção (PCP) baseada em zonas de trabalho tem como vantagem explicitar o fluxo de trabalho ao longo das unidades de produção, podendo ser associado ao Sistema Last Planner (LPS) e a modelos BIM 4D. Entretanto, ainda existem algumas lacunas de conhecimento, tanto práticas como teóricas, referentes à implementação desta abordagem, principalmente relativas à aplicação de conceitos e princípios da filosofia da produção enxuta e a interação destes com as funcionalidades BIM. Destaca-se a necessidade de desenvolver estudos sobre métodos de PCP que considerem a natureza parcialmente repetitiva das atividades de construção e aspectos relacionados à gestão dos fluxos de trabalho e do produto. O presente trabalho propõe um método para PCP baseado em zonas de trabalho com o apoio de BIM, e explora a sua interface com o LPS. A abordagem metodológica utilizada foi a Design Science Research, sendo conduzidos dois estudos empíricos em empresas atuantes no mercado imobiliário. As principais contribuições do método proposto estão ligadas às ferramentas utilizadas, que podem potencialmente contribuir para aumentar a qualidade da informação, principalmente relacionadas a fluxos de trabalho, e dar suporte para a tomada de decisão colaborativa.

Purpose 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. Design/methodology/approach 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. Findings 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. Research limitations/implications 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. Originality/value 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.
