About this file
This is an Addendum 1 memorandum issued by AVI Professional Corporation to the City of Cheyenne, Wyoming, Purchasing Manager TJ Barttelbort on March 20, 2026, regarding modifications to Invitation for Bid No. S-19-26 for the Storey Boulevard Extension Construction project. The addendum introduces significant changes to the original bid package, including nine newly added items related to base course grading, sewer manhole adjustments, mailbox assembly installation and removal, and temporary and permanent fencing work. Conversely, the addendum deletes one bid alternate and three existing crushed base grading items, while modifying quantities for three existing line items: Concrete Curb Fillet (reduced to 4 each), 4-Wire Fencing (increased to 6,856 linear feet), and Post & Rail Fencing (increased to 210 linear feet). The addendum also requires removal and replacement of six plan sheets (sheets 8, 9, 10, CE0, STD4, and STD5) and modification of the fencing specification section, with the addition of a new Geotechnical Report to the project documentation package. Given the March 20, 2026 issuance date and the original sealed bid deadline of March 31, 2026, this addendum provides contractors with eleven calendar days to incorporate the revised bid items, plan modifications, and technical specifications into their proposals.
No pricing information, set-asides, incumbent contractor identification, or funding sources are disclosed in the addendum memorandum itself. The document serves solely as a notification vehicle for technical and scope modifications to the original bid package and does not address contract terms, payment structures, insurance requirements, or other administrative conditions previously established in the base solicitation documents.
