Form / Attachment / Pricing Sheet

This document is an Excel spreadsheet containing a detailed breakdown of line items for a project, likely related to bridge construction and design. It appears to be a pricing sheet or a detailed scope of work with associated cost categories.

• Item: A sequential numbering of tasks or components.
• Description: Details the specific work item, such as "Phase 1: Site Investigation & Analysis," "Phase 2: Bridge 1 Design," and "Phase 3: Bridge 1 Construction." The items cover design and construction phases for multiple bridges (Bridges 1, 4, 6, 8, 8-A, 9, 10, 11, 12, 13, 16, 17, 18, 19, 23, 37, 38, 39).
