Oregon Standard Drawings and Oregon Standard Details

The purpose of Oregon Standard Drawings and Oregon Standard Details is to provide information as a convenience to those who access them. These Drawings and Details are also intended to communicate design standards and practices to the Design Engineer. What are Standard Drawings? Standard Drawings are stamped by an ODOT Engineer of Record and are backed by engineering analysis, calculations, and/or other justification to support them. Standard drawings are available for use on public work projects, but cannot be modified by designers on a project-by-project basis. It is the responsibility of the project professional of record that standard drawings are used as originally intended. Standard drawings are compliant with Oregon Standard Specifications. What are Baseline Reports? Baseline Reports are additional data for a designer to use. This gives background and assumptions used in the development of the standard drawing. This report date is shown on the standard drawing. What are Standard Details? Standard Details are tools used to quickly add detail to a specific project. Generally these fit into 3 scenarios. 1) A template that needs project specific data added. 2) A new design style that is being tried, or 3) The item is not used often such that updates may need to be added. Standard Details may require modification by the project professional of record. Standard Details are intended to be the responsibility of the project professional and as such incorporated into the project plans. What is the Effective Date? On each Oregon Standard Drawing there is an effective date. The drawings are used by multiple government agencies and not all include Standard Drawings in the plan set. The bid date of the project will be in the range of the effective date. This assists with identifying the correct drawing for the project. The Standard Drawing is valid for the life of construction of the project.
