Sequencing and Placement of Noise Walls and Retaining Walls on Complex TxDOT Projects

Difficulties arise when constructing noise wall and retaining walls due to conflicts with utilities, construction phasing conflicts, and inadequate access. Design manuals and design guides from the TxDOT and various other Department of Transportations (DOTs) around the United States mention items to consider during design. These manuals mention utilities and other aspects of construction as potential issues when designing noise and retaining walls but fail to provide details about how to avoid or address these issues. The purpose of the research is to provide guidance on the sequencing and placement of noise walls and sound walls on complex projects. The research includes examining issues such as noise and retaining wall selection, standards and specifications, preferred methods and best practices for sequencing and placement, and design and construction procedures. In addition to the report, the deliverables of the research include a guidebook for the sequencing and placement of design features and recommendations for additions to the TxDOT manuals.
