Office of Contract Sales & Estimating
The Item Master is a list of all the items of work that are used by ODOT. Each item of work has an associated item number, item extension, description, and unit of measurement. When developing construction plans, the items of work listed on the General Summary should exactly match the item numbers, item extensions, item descriptions, and units of measurement in the Item Master. The item numbers in the Item Master correspond to the item numbers in the Construction and Material Specifications (C&MS). The C&MS contains information about each item such as a description of the work, materials and equipment, method of measurement, basis of payment, etc.
The Item Master is updated frequently, sometimes several times a week. The Office of Estimating recommends saving the Item Master as a favorites link rather than downloading the file to ensure you are always viewing the most current version.
