A Suggested Model Using Quantitive and Qualitative Parameters for Cost Engineering of Mechanically Stabilised Earth Walls in Egypt

Abstract

To investigate current trends, existing international options and proposed new Technology in the Egyptian market, a model is suggested to define a method to assess by quantitative and qualitative methods, a cost Engineering approach to analyse suitable solutions. The numerous options of Mechanically Stabilised Earth Wall (MSEW) Technologies available internationally creates a difficult exercise to assess and establish accurate comparisons and evaluation criteria to arrive at a suitable choice of Technology, to be embraced in a developing market such as Egypt post 2011. The investigation into historically advanced and new MSEW technology begs the need to simplify the assessment process with a model, to clarify, best practice and economic criteria, in a method that demonstrates the least bias. A method has been proposed that allows Technology leaders and enterprising new comers to contribute to the understanding by Professionals and the layman on the merits of MSEW Technology, to maintain and promote the body of knowledge and state of the art of MSEW technology. The specific examples of geogrid soil reinforcement, concrete cladding panels, concrete block and steel mesh baskets used in MSEW projects in Egypt has been used from current contracts to demonstrate the assessment criteria and proposed model.
