Notice to Contractors _ MALD Pilot _ Hashing .pdf

This is a Special Notice to Contractors issued by the Georgia Department of Transportation (GDOT) regarding Project PI#0016469, a roadway or bridge construction project scheduled for the December 2026 letting. The project will be let as a special letting using a Model as Legal Deliverable (MALD) approach, under which specific elements of the digital design model will serve as contractual deliverables alongside traditional construction documents and plans. The bid package will be available on BidX on October 23, 2026. Digital deliverables are indexed in the 01 Series of the plans package, with each file accompanied by a unique 64-digit SHA-256 hash code to ensure that contractual digital deliverable files have not been modified. A SHA-256 verification tool has been developed to enable contractors to authenticate that digital deliverables match the version certified by the Engineer of Record.

The GDOT has provided a web-based SHA-256 verification tool at https://main.d1lkuixhq2ym17.amplifyapp.com/ to assist contractors in verifying digital deliverables by dragging and dropping files for authentication; however, use of this tool is voluntary and offered for contractor convenience. Contractors should consult the Notice to Contractors for project descriptions, locations, estimated quantities, and Specification Section 102 for bidding requirements and conditions. Additional project details and bidding information can be accessed through the Georgia Department of Transportation's website at http://www.dog.ga.gov/GDOT/pages/business.aspx by selecting BidX/Letting and the appropriate letting month.
