Lean construction tools and researches roots back to Toyota Production System (TPS). There are very few studies available which analyses lean construction literature regarding TPS principles to identify its compliance and also not many studies stretches the overview of researches published in lean construction.The purpose of this study was to structurally organize the International Group of Lean Construction (IGLC) conference proceedings and examine its compliance towards Toyota Production System (TPS). The adopted methodology was content analysis by reviewing 123 research papers published by IGLC in year 2016.
Literature review revealed that construction should be considered as flows and process to identify and eliminate waste for successful lean implementation. Various types of waste, their origins in construction and causes are discussed to apply relevant lean principle as a solution from production industry. Tools mentioned in the IGLC studies are discussed briefly. Six step research was carried out to conduct Content Analysis on IGLC studies constructing various categories. This categorization summarized into a single table and from this table various charts generated representing trends in lean construction with the help of Microsoft Excel software.
The results of analysis suggested that overall 54% lean construction research followed TPS framework completely. The Last Planner System (22%) is most common used lean tool followed by Lean Project Delivery (21%) and West Reduction (9%) amon others. The researches which followed TPS were classified into four main categories of TPS framework (Philosophy (15%), Process (69%), People & Partners (4%), and Problem Solving (13%)) and others (50%) were assigned Non-TPS categories according to their context. Further trends are presented in form of charts like Case Study research (43%) & literature research (24%). The findings are compared to similar study in past to add time aspect in lean research trends. This result provides guidance to future researchers in Lean Construction about demanding research areas in construction like human aspects of lean and suggests not to limit their work for only particular sectors of construction like Building Construction (40%) & Infrastructural works (5%). Results can also be used as a reference to avoid duplication of work which is already explored and to develop those works a step further.
