Study of Unit Price for Competitive Bidding Based on CCI (Construction Cost Index) for Building

Abstract

— Competitive bidding on construction projects involving decision making under uncertainty in the form of subjectivity of the bidders. The Bidders who understand these conditions will have the biggest chance to win the tender. The value of the uncertainty to win this tender should be measured based on the factors that influence decisions. This study will be assessed based on economic factors and strategic costs. Contractors generally tend to concentrate their work in geographic locations that they understood clearly. Assessing the unit price offer is essentially the same as reviewing contractual unit price, because it is a contractual winner competitive bidding. Approach to economic factors studied variable CCI (construction cost index) which is the level of construction cost, which reflects a value of the building / construction characteristics of the area. Approach to factor bidding strategies assessed by the difference between the contractual price and the Standard Unit Price for building state. Refer to these conditions then, to get the price of competitive bidding, as well as responsive to the market price. A model is presented in the form of a model Y = 2,68 X – 0,3734 will be normally distributed with a standard deviation of 0,4445. Where Y is the unit price of bids (IDR, in millions) And X is CCI Index. CCI is the only driver variables to calculate the standard unit price for building State (HSBGN), by with R2 is 1, (Abstract) Keywords— Competitive Bidding, uncertainty, CCI (construction cost index), contractual
