Key factors of success in the application of last planner system in construction work

Abstract

This study aims to identify what factors are the key to the successful implementation of the Last Planner System in construction work based on existing journals to be applied in the construction environment and determine the priority weight / key factors of success from the questionnaire results from experts with the Analytic method Hierarchy Process. The method used in this study uses the Analytic Hierarchy Process to find priority weights and software uses Expert Choice. From the results of the analysis obtained Key Success Factors in construction work, namely as many as 10 criteria where stakeholder criteria with the highest priority weight with a global weight of 0.2279 which have a value of consistency ratio below 0.1 or 10%, ie 0.08 or 8%, then an evaluation of the comparison pairing between criteria is consistent and as many as 24 sub-criteria where the sub-criteria of stakeholder support for the implementation of LPS with the highest priority weighting with a global weight of 0.1812 which has a consistency ratio below 0.1 or 10% ie 0.07 or 7%, then an assessment of pairwise comparisons between sub criteria are consistent.

Application of last planner system with BIM in construction plan management

“…As a production planning system, the LPS can improve the reliability of planning and reduce the variability of work in programming, design, construction and commissioning of projects [1], [2]. The LPS tries to eliminate the limitations of the critical path method (CPM) which only focuses on activity and duration while damaging the flow [3], [4].…”

“…The LPS tries to eliminate the limitations of the critical path method (CPM) which only focuses on activity and duration while damaging the flow [3], [4]. The Lean Construction Institute (LCI) defines LPS as "the LPS is composed of 5 elements： (1) The master schedule identifies the objectives of the phase schedule and defines the major deliverables for construction, fabrication, and procurement, (2) The Phase schedule is more detailed to help the project team allocate staff, materials, and budget, (3) The function of forward plan is to improve the reliability and process of work, and to ensure that the workflow matches the resources of staff, materials and funds, (4) The weekly work plan is made by the production supervisor and foremen, updated daily (5) Continuous Improvement: measuring the metrics developed for planning work in order to find problems and make improvements in time, repeat the process. " [5] Building Information Modeling (BIM) provide a sharing information platform which allocated resources between various trades for reducing variability in workflow [6], [7].…”
