Barriers to Implement Lean Principles in the Indian Construction IndustryAM Publications
Lean construction emerged from attempts of transferring and applying the Japanese Lean production
philosophy to the construction industry. Lean construction is a confluence of ideas including continuous
improvement, flattened organization structure, efficient usage of resources, elimination of waste, and cooperative
supply chain. Based on the success of Lean Production in manufacturing and the development of Lean Construction
in countries such as Brazil, Denmark and the USA, the application of Lean Construction is currently debated in India.

construction sector. The data was collected by questionnaire survey of project managers of building construction
organizations and senior consultants of architectural and project management firms. The data collected was then
analyzed to rank the main barriers and lean principles are suggested to overcome these barriers

Lean Construction - Approach Capable of Dealing with Complexity and UncertaintyIJERA Editor
The construction projects involve various risk factors which have various impacts on objective that may lead to low productivity and time-overrun. One way of contributing to the productivity improvement is to implement lean. Lean or lean thinking was implemented for the first time by the car manufacturer Toyota and has been used in the manufacturing industry for decades. In the construction sector, lean have not been implemented as much as in the manufacturing industry and therefore there is room to take lean further in construction projects. The aim with lean in construction projects is to utilize the resources as labor and material better to get less waste, fewer delays and lower costs or, in other words, to minimize the Non-Value adding Activities. The objectives of this paper are to provide with fundamental knowledge and benefits of Lean Construction and its capability to enhance performance in construction thus the quality of life for future Indian construction sector.

IRJET - Fuzzy Logic Approach in Construction Delay AnalysisIRJET Journal
This document discusses the application of fuzzy logic to analyze delays in construction projects. It presents a case study of a housing project in Kochi, Kerala, India. Fuzzy logic was used to quantify the probability of scheduled delays. Based on expert interviews, fuzzy rules were created to assess various delay factors. These included labor, project, consultant, contractor, and external related factors. The factors were applied to the case study project using MATLAB fuzzy logic toolbox. This resulted in a scheduled delay probability of 32.9% compared to the actual schedule. The document concludes fuzzy logic can help construction parties predict delay risks and improve project time management.
Lean construction aims to transform project management by removing waste and improving productivity, quality, schedules and costs. It draws from lean manufacturing principles to minimize non-value adding activities through tools like target value design, pull scheduling using the Last Planner System, and building information modeling (BIM). Integrated project delivery brings project teams together early through lean contracts to collaboratively design-to-budget and optimize the whole project, rather than sub-optimizing parts. This new approach requires transforming project culture from adversarial to relational and focusing on customer value and continuous improvement.
