Abstract - Lean is a business philosophy, not just a tool set
specification to cover legal ramifications both real and perceived, problems that Lean construction seeks to solve. Evidence from three LCI-funded research sources show that projects that implement Lean building tools and techniques have much better outcomes across a variety of benchmarks. Lean methods of maximizing stakeholder value while reducing waste by emphasizing collaboration between teams on a project. The goal of Lean construction is to increase productivity, profits, and innovation in the industry. Lean Construction is a project delivery process that uses Lean methods of maximizing stakeholder value while reducing waste by emphasizing collaboration between teams on a project. The goal of Lean construction is to increase productivity, profits, and innovation in the industry, while minimizing waste. It focuses on increasing workflow efficiency and maximizing profit without exerting more effort or requiring additional resources.
or method for improvement. This business philosophy was derived from Toyota experiences and from its Toyota Production System (TPS). It focusses is on reducing waste in all business processes, reducing cost and lead-time as well as an increasing the quality. This paper explores the principles of Lean Philosophy as applied to project management processes. This will be an introduction to the advantages of applying Lean tools and techniques to Projects. It is time for the world of projects to reap the same kind of benefits that Lean has achieved for manufacturing, - maximizing the value and minimizing waste. Proper use of Lean techniques resulted in cutting waste in the projects, producing greater customer satisfaction and improved profit margin. The goal of this paper is to provide participants with an understanding of how using Lean principles can help ensure project success. The objective is to explore how Lean principles can be applied to project management and to determine the conditions within can be successfully implemented.
Lean construction uses the principles such as Value, Value Stream, Flow, Pull and Perfection and applies them to construction industry to eliminate waste [10]. Lean philosophy applied to construction focus on waste elimination, improving quality, creating a pull system with continues flow without bottlenecks that meet the customer's requirements, involve employees at each level, suppliers, and client within the project process, investing inbuilding in quality and continuous improvement. Activities taking place in construction can be divided into following two categories: conversion activities that lead tangible outcome and flows activities which fasten such conversion activities within the delivery. Research has discovered that significant waste lies in that flow processes [3]

1.INTRODUCTION 1.1 Lean Philosophy and Construction Industry Its common at Construction Industry [1] projects have significant delays and budget overruns. Lean construction methodology is efficient in eliminating the types of waste in a construction project such as defects, overproduction of goods, inventory, motion, transportation, waiting, over processing and not out utilizing talent. Over processing includes over engineering, apply similar document, duplicate forms and getting double supply estimation. Any step in a process that is not adding any value the project can be considered as overprocessing. Not utilizing talent includes bad quality training assigning wrong people to significant roles, not effective admin tasks, poor ways of communication, poor management, lack of effective teamwork and in general issues causes inefficient management of human resources. Eliminating above issues get away the relevant waste leading to more and efficient productivity.
1.2 Methodology By its nature, this paper is an integrative literature review. This is a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated [4]. Integrative literature reviews can be structured using a set of competing models and information. No data were generated or analysed during the study. At the first part of this paper the lean concept and their principles is presented while follows the connection among lean philosophy and construction projects and the implementation of Lean principle to them. The paper highlights the barriers to this and the connection between
A lack of trust [2] within the construction sector has created systems of checks, double-checks and over
