00015934 Exhibit 8 Description of Base Bid and Add Alternate.docx

This is an Exhibit document for an Oregon Department of Transportation (ODOT) construction project outlining the bidding structure for a roofing project. The base bid requires contractors to provide all labor, materials, equipment, and supervision to remove existing metal roofing, flashing, and trim for reinstallation after disposal of old insulation and installation of new roof sheathing and vapor barrier. Add Alternate 1, if selected for inclusion, requires contractors to perform all base bid work while also removing and disposing of existing metal roofing, flashing, and trim, and providing new metal panel roofing and trim according to project specifications. The contract award will be based on the lowest responsive bid combining totals from the base bid and add alternate 1.

ODOT has limited funding available for this project and may not have adequate resources to construct the entire scope. If funding permits, Add Alternate 1 will be selected for inclusion in the project award. Both the base bid and add alternate must comply with all contract specifications, plans, and statement of work requirements. This bidding structure allows ODOT to maximize the work completed within available funding constraints while maintaining flexibility in project scope.
