Lean Principles an Innovative Approach for Achieving Sustainability in the Egyptian Construction Industry 4 From 11
Research Methodology
In order to achieve the aim of this research, a research methodology, consisting of literature review, case studies and survey questionnaire, is developed to accomplish five objectives.
- 1. Building a comprehensive background of the research topic by investigating the concepts of sustainability and (LPs),highlighting their relationship as well as discussing the ability of (LPs) to achieve sustainability objectives.
This objective was achieved through conducting an in-depth literature review depending on textbooks, academic journals and professional magazines, conference and seminar proceedings, dissertations and theses, organisations and government publications as well as Internet and related websites.
- 2. Presenting and analysing four case studies to explore how (LPs were applied to deliver sustainable projects.
These cases were extracted from literature review and covered different project types in different countries including: residential complex in Brazil (Mota at al., 2005), industrial house builder in Sweden (Jansson et al., 2009),health care facility in Canada (Breen,2011) and precast concrete production in Singapore (Wu and Low, 2010).
Although there are many case studies about (LPs), the studied cases were selected as they are focused on applying (LPs) to achieve sustainability objectives.
They were selected from different geographic areas, with diverse scope, nature, size and construction phases which helped accomplishing the study objectives and its argument.
These case studies were analysed qualitatively through focusing on the application of (LPs) towards achieving the objectives of value, value stream, flow, pull and perfection.
- Presenting and analysing results of a survey questionnaire conducted with a sample of (ECFs) to investigate their perception and application of (LPs) to achieve sustainability in construction projects.
The survey questionnaire consisted of two sections.
