考虑工期成本时确定最优报价的方法

Method to determine optimum contract bid on consideration of time cost

介绍了国外出现的"报价+工期+奖罚机制(incentive/disincentive)"的投标模式,并对其作必要的分析。要求投标者不仅要提供传统意义的项目施工成本报价,还要提供完成项目的建设工期,同时业主制定一个奖罚机制,以此达到既节约费用,又减少工期的目的。建议投标者在制定策略时,要对项目成本、工期和奖罚机制进行综合考虑,以此来确定合适的投标报价和工期。

In traditional invitation to tender,contractors are merely required to submit a bid price with a complete time specified by the owner. In order to improve investment effectiveness a number of owners require the contractors to submit both price and completion time. There is ＂A （cost） ＋ B （time cost） ＋ I/D （incentive/disincentive）＂biding concept abroad,it is designed to shorten the total contract time by allowing each contractor to bid the number of days in which the work can be accomplished,in addition to the traditional cost bid. I/D are not only used to provide an incentive to the contractor for earlier completion, but also to provide a disincentive for ate completion of a project. Contractors are then presented with the problem of determining the best strategy of bid estimation, including construction cost ,time cost, and incentive/disincentive.
