Resumo O modelo tradicional de planejamento adotado por grande parte das empresas construtoras utiliza como base o método CPM (Critical Path Method). No entanto, devido às limitações deste método, muitas empresas utilizam ferramentas auxiliares para o atendimento das necessidades das equipes de produção, causando dúvidas nas equipes quanto ao trabalho a se realizar, às atividades a serem priorizadas e à melhor utilização dos recursos. O objetivo desta pesquisa foi elaborar um modelo integrado que preenchesse as lacunas do planejamento tradicional (baseado no método CPM), e que contemplasse elementos dos sistemas de planejamento LBMS (Location-Based Management System) e LPS (Last Planner System). O modelo foi desenvolvido a partir de um estudo de caso exploratório, adotando-se como base o método CPM, incorporado aos conceitos do PMI (Project Management Institute), e os sistemas de planejamento LBMS e LPS. Possui como uma das características a inclusão de processos para integração dos três sistemas nas seguintes fases dos empreendimentos: iniciação, organização e preparação, execução do trabalho e encerramento. O modelo proposto poderá compensar as limitações de sistemas de planejamento e controle da produção que utilizam ferramentas de maneira fragmentada, uma vez que promove a complementaridade e a sinergia entre eles.

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.

The application of lean construction theory in building green substation was discussed. The study on integration of design-build indicated that the electric power design institute as the general contractor should change the mode of only setting up one secondary organization to manage the engineering, and should improve the management system and change the producing idea. The study on the combination of the last planner system and building the substation indicated that the measures of arranging the work and setting the workload reasonably and enhancing the supply of important resources etc. could increase the Percent Plan Complete of building the substation. At last, the 4-saving and 1-environmental protection measures of green construction of substation were brought out.

Production of the aircraft becomes very important to facilitate many passengers of aircraft in Indonesia in the future. The design of a very complex aircraft requires proper project management. This study aims to perform the best scheduling project of empennage structure design of Indonesia’s aircraft with limited resources. Critical Path Method (CPM) is used to schedule the project based on activity and resource. CPM scheduling results in completion time for activity data for 400 working days. CPM scheduling after assigning human resources results in a longer completion time for 1023.47 working days. CPM scheduling is carried out by reallocating of human resources to produce a shorter completion time, and it results in completion time for 955 working days.

Along with the industrial competition nowaydays, an exact and strategic planning is highly required particulary for project. There are alot of tasks and activities within, which need to be broken down, in this term for its time line. Every success and failure is caused by raw palnning. The obyective of this research is to find efective time needed to complete a project. Method used are Critical Path Method (CPM) , Program Evaluation and Review Technique (PERT), andGantt Chart.

With capital projects consistently running late and over budget in urban economics, it is time to look at project managers could do to step up their implementation success and performance. In real estate industry, China, there are many uncertainties and risks for project management. Lean has been continuously adopted in the construction area as an innovated effort striving to improve productivity and to value clients’ needs. Comparing with traditional construction management, this paper proposes some applications in Lean including Last Planner System (LPS) to identify uncertainties and provide solutions.

Critical Chain Project Management (CCPM) provided a tangible progress to the Project Management Body of Knowledge. The critical chain project management (CCPM) differs from the traditional Critical Path Method (CPM) which includes never changing resource dependencies. CCPM improves the project plan by aggregating uncertainty into buffers at the end of activity paths. In this research, one hundred twenty random projects were generated and analyzed using Microsoft Project software according to the traditional CPM and the CCPM once using the sum of squares (SSQ) method and another using the cut & past (C&PM) method. CCPM-SSQ method revealed an average savings of 13% and 43% in duration and cost, with a standard deviation of 21 and 11 for duration and cost respectively. While the CCPM-C&PM method revealed an average overestimation of about 2% in duration and 43% savings in cost, with a standard deviation of 25 and 11 for duration and cost respectively.
