Event Description/Abstract

On November 18, 2009 the Federal Highway Administration (FHWA) approved the innovative contracting process of the Indiana Department of Transportation (INDOT) for alternate pavement bidding on multiple projects. This process involves only one set of plans with the choice to bid either Portland Cement Concrete Pavement (PCCP), or Hot Mix Asphalt (HMA) Pavement, or both typical pavement sections. A Present Worth (PW) cost was calculated for future maintenance costs of both pavement types using an established Life Cycle Cost Analysis (LCCA) Strategy. This PW cost was added to the respective pay items after the bids were opened, but the PW cost was only used to determine the low bidder. INDOT has actively involved the Asphalt Pavement Association of Indiana (APAI), the Indiana Chapter of the American Concrete Pavement Association (ACPA) in the development of this procedure.

The primary reasons INDOT implemented this innovative contracting practice for alternate pavement type bidding are:

1. Attract more bidders and competition.

2. Obtain true cost savings over similar conventional bid projects.

3. Provide a more competitive market, i.e. lower bid costs on paving items using this procedure versus the standard procedure where the pavement type is pre-determined.

In 2012 the FHWA issued a memorandum and Technical Advisory T-5040.39 providing the specific requirements that a State DOT must meet to utilize Alternate Bidding for Pavement Type Selection. INDOT continues to use the process as standard practice form most all new reconstruction and new alignment projects.
