Addendum No. 1, dated November 2, 2026, replaces the links to the project drawings and documentation in Part 1 of the bidding documents and leaves all other terms unchanged. Bidders must attach a signed acknowledgment of Addendum No. 1 to their proposal, and the original proposal document must be signed separately.

Scope covers design and construction of the new Route 670 Connection, Route 29 auxiliary lanes, right-of-way acquisition, traffic signals, drainage, signing and pavement marking, stormwater management, a Transportation Management Plan, erosion and sediment control, and utility relocations within the project limits. The design-builder must furnish all design, construction services, materials, equipment, tools, and labor.

The attached contract form is a 2016 lump sum design-build agreement between Greene County, Virginia and a design-builder for the same project. It sets the following terms: the county issues Notice to Proceed within fifteen days after the Agreement Date; the design-builder submits a Preliminary Schedule within fifteen days of Notice to Proceed and a Baseline Schedule within ninety days; progress payment applications are due on the tenth of each month, with payment within thirty days of receipt; retainage is not withheld; liquidated damages accrue daily for missed final or interim milestones; performance and payment bonds each equal one hundred percent of the Contract Price; and the county retains ownership of all work product. Price adjustments for asphalt and fuel are available under Exhibits 6.3(a) through 6.3(c) only if the design-builder declares intent in its Price Proposal. The contract price includes all applicable sales, use, and consumer taxes.
