The low bid method has been the most common competitive bid selection approach used for public projects in the U.S. construction industry. This method is usually coupled with a prequalification process to ensure that the lowest bidder has the financial capacity, the necessary experience, and...

This paper is concerned with predicting the probability of tendering the lowest bid in sealed bid auctions. Four of the leading models from the bidding literature are shown to be subsumed within a general model – differing only in their method of parameter estimation. These models are then...

Many of the North American railroads have introduced differentiated services for grain shipments in the past decade. Most interesting have been innovations in guaranteed railcar service which have evolved since their inception. In most cases, pricing and allocation of these services have used...

Many of the U.S. railroads have introduced highly differentiated services for grain shipments in recent years, generally in the area of forward guaranteed car service. Taken together with other alternatives, these mechanisms have had the effect of establishing priority allocations among...

The outline of a proposed new unbalanced bidding model is discussed. Background is provided as regards the role of item price loading, otherwise known as unbalanced bidding. Three types of loading are described, namely those of ‘front-end loading’, ‘back-end loading’ and ‘quantity...

This paper is concerned with the effect of outliers on predictions of the probability of tendering the lowest bid in sealed bid auctions. Four of the leading models are tested relative to the equal probability model by an empirical analysis of three large samples of real construction contract...
