A New Design Solution to Reduce the Cost and Time of Bridge Construction: GRS-IBS

Length: 1 hour AIA Provider Number: J374      AIA Course Code: OC109      AIA Credit: 1 LU/HSW LA CES Course Code: OC109      LA CES Credit: 1 PDH (HSW) DP PDH: 1 PDH for EngineersThis program will provide an overview of Geosynthetic Reinforced Soil – Integrated Bridge System (GRS-IBS), a bridge design concept being promoted by the Federal Highway Administration to accelerate construction time and offer significant cost savings for the construction of local, county and state bridges. Segmental Retaining Wall (SRW) facing elements, along with geosynthetic reinforcement material, is proving to be a viable solution for a majority of the bridges known to be structurally deficient and in need of replacement across our nation.

Overview: 

This program will provide an overview of Geosynthetic Reinforced Soil – Integrated Bridge System (GRS-IBS), a bridge design concept being promoted by the Federal Highway Administration to accelerate construction time and offer significant cost savings for the construction of local, county and state bridges. Segmental Retaining Wall (SRW) facing elements, along with geosynthetic reinforcement material, is proving to be a viable solution for a majority of the bridges known to be structurally deficient and in need of replacement across our nation. The presentation addresses the design concept, key materials, specifications and important construction details. A case study example illustrating the construction sequence is also provided.

Learning Objectives: 

  •  Participants will learn the advantages and limitations of a GRS-IBS and what makes these systems so cost effective compared to traditional methods.
  •  Participants will be able to describe the key components that make up a GRS-IBS structural system.
  •  Participants will understand the design process for a GRS-IBS system, and what is included in project drawings and specifications.
