Lean Approach to Scheduling in Construction Projects
Abstract
Scheduling of activities are of utmost importance when starting a new project whatever scale it might be on. It is done to ensure the resources are used efficiently and in most cost effective way[1]. According to PMI (2013) the Plan Schedule Management Process may involve “choosing strategic options to estimate and schedule the project such as: scheduling methodology, scheduling tools and techniques, estimating approaches, formats, and project management software”[2].
There are various methods and techniques for scheduling of which the most widely used are the Critical Path Method (CPM). CMP is primarily an activity based method that takes the activity as the unit of focus, and is often presented in a Gantt Charts[1]. However, criticism of the CPM and Gantt Chart has been raised, specifically in the case of construction projects, for not sufficiently supporting management during the construction phase, and not creating a continuous, and thus financial, flow of resources [3][4].
Delete: Lean thinking aims at optimizing production flow and eliminate waste of resources. The ideology is adjusted to the construction industry and called Lean Construction. Lean Construction methods are becoming common practice on construction projects with the use of the Last Planner System (LPS) and Location Based Scheduling (LBS) as planning and scheduling tools [5]
The Location-based Scheduling (LBS) methodology is designed to plan and manage workflows and may therefore be expected to be a useful alternative to CPMCite error: Closing </ref> missing for <ref> tag
