When a lump-sum public construction project is implemented, disputes often arise concerning issues around the accuracy of contracted quantities, the acceptability of unit prices of cost items, and whether an "equal (or equivalenty)" for a product (equipment or material) can be used. In Taiwan, contracted quantities and unit prices are primarily based on owner's estimations, and the trademarks of a product specified in a tendering documentation are only for reference. A contractor has to struggle for profit when the amount of work completed differs from the contracted amount, when change orders are priced according to the owner's estimates, and when inexpensive equals may be used. This work comprehensively elaborates the background of the current practice, and presents experience of applying an electronically facilitated bidding model to evaluating the bidder's submitted quantities, unit prices and equals in several practical projects in Taiwan. Results of this study indicate that the aforementioned construction disputes can be prevented or at least mitigated. (c) 2005 Elsevier B.V. All rights reserved.

Construction clients usually tender their projects by either the lowest bid tendering method or the A-plus-B method to find a bidder that provides the lowest cost or highest profit. However, choosing a contractor that provides assured quality by examining his construction proposals along with his bid price and bid duration will compensate for the uncertainty in the lowest bid system, while retaining the advantages of the A-plus-B method. This paper presents a novel tendering method (the Most Advantageous Tendering approach) using a practical example in Taiwan. The rationales for contractor selection of the Government Procurement Law in Taiwan are reviewed herein. Several valuable issues regarding contractor selection in this case study are also presented.
