Workplan for SEP-14 Project "Best Value Alternative (A - D) Bidding "
Iowa Department of Transportation
Introduction
The Iowa Department of Transportation submits this work plan for review and approval as a Best Value Alternative bidding procedure under the provisions of Special Experimental Project No. 14 (SEP-14) for use of innovative bidding practices.
Purpose
The purpose of this specification is to allow the Contracting Authority to obtain the most work, or the best options, for the available funds that have been allocated for the project.
Scope
The Contracting Authority has traditionally made pre-letting choices on their willingness to pay additional cost for one design or material over other designs or materials. In Best Value Alternative Bidding, the Contracting Authority expands the choices of designs or materials it is willing to award, and includes the basis for low bidder selection of these designs and materials in proposal.
The proposal will have Alternative Sections. The proposal will also list a dollar value (Alternative Differential) that the Contracting Authority bas pre-determined it will pay for each Alterative Section over the Base Alternative Section. For each set of alternatives, the contractor will be allowed to bid ONE Alternative Section (e.g. either the Base Alternative Section or Better Value Alternative Section. The basis for determining the low bidder for consideration for award will be the contractor who submitted the lowest Bid Total for minus the sum of the Alternative Differentials for that contractor (e.g. A - D Bidding)
