Reinforced Soil Structures: From Standard Design to BIM

Abstract

Building Information Modeling (BIM) emerges as a new process for the architectural, structural, engineering and construction sectors. It is based on three-dimensional (3D) parametric models which centralizes geometrical, physical and project information. The implementation of BIM within the Geotechnical Engineering sector has not reached yet a good level of robustness, frequently appearing as a new concept. BIM methodology in geotechnics and in the design of Reinforced Soil Structures (RSS) represents an opportunity which could enable the AECO world (Architecture, Engineering, Construction, Owner and Operator) to implement the infrastructural BIM, managing complex projects. With BIM, it is possible to improve the construction quality and reduce the wastage of the supplied materials as it allows an overview of the construction models through multidimensional digital design solutions which provide simulation and analysis by using different design software. This paper aims to clarify issues which might arise during the BIM design of RSS. In particular, this paper presents the case of a Mechanically Stabilized Earth (MSE) wall which comprises precast concrete facing panels and discrete high adherence polymeric soil reinforcing strips. The application of BIM technology in this research provides guidelines for design optimization and construction improvement.
