00015787 Attachment D Description of Base Bid and Add Alternates~1.docx

This is an Attachment D document describing the base bid and additive alternate for the Prineville Maintenance Station reroof project administered by the Oregon Department of Transportation (ODOT). The base bid scope requires the contractor to provide all labor, materials, equipment, and supervision to install a new roof system on the ODOT Maintenance Station in Prineville, Oregon, with work including installation of a standing seam roof system with concealed fasteners and mechanically locked seams over the existing roof on a sub-purlin system, installation of new flashing systems at all roof penetrations, and completion in accordance with the project schedule, safety regulations, quality control protocols, and all applicable building codes. The base bid explicitly excludes snow guards from the scope of work.

ODOT has limited funding available for this project, which may not be adequate to construct the entire scope. One additive alternate has been included in the bidding process to maximize the work completed within available funding limits. Add Alternate 1 consists of the supply and installation of snow guards as shown in the project documents and will be selected for inclusion in the award if funding allows. The contract award will be based on the lowest responsive bid combining the base bid total and Add Alternate 1 total, with both portions required to comply with all contract specifications, plans, and the statement of work.
