ARTICLE 17 ENGINEERING NEWS RECORD CONSTRUCTION COST INDICES ADJUSTMENT OF THE ADJUSTMENT FACTORS 17.1 Economic Price Adjustment: The Adjustment Factors may be updated on each anniversary of the Contract date to account for changes in construction costs, provided, the Contractor requests in writing, approximately thirty (30) days prior to the anniversary of the Contract date, that the Adjustment Factors be updated. Such request shall be delivered to the City and to the Consultant/Gordian. In the event the Contractor fails to deliver the request timely, then the City will determine the date on which the Adjustment Factors will be updated, but in no event will such date be later than thirty (30) days after the written request is received by the City. Thereafter, the Contractor's Adjustment Factors will be adjusted according to the following: 17.2 The Contractor's Normal Working Hours and Other than Normal Working Hours Adjustment Factors will be adjusted according to the following: 17.2.1 A Base Year Index will be calculated by averaging the 12-month Construction Cost Indices (CCI) for the average of the twenty (20) cities published in the Engineering News Record (ENR) for the twelve (12) months immediately prior to the month of the bid due date (e.g. April bid date, Base Year Index is April of the prior year to March of the bid date year). 17.2.2 A Current Year Index will be calculated by averaging the 12-month Construction Cost Indices (CCI) for the average of the twenty (20) cities published in the Engineering News Record (ENR) for the twelve (12) months beginning with the month of anniversary of the bid due date (e.g. April bid date, Current Year index is April of the prior year to March of the current year). 17.2.3 The Economic Price Adjustment will be calculated by dividing the Current Year Index by the Base Year Index. 17.2.4 The Contractor's original Adjustment Factors will be multiplied by the Economic Price Adjustment to obtain the Contractor's new Adjustment Factors effective for the next twelve (12) months. 17.2.5 Averages shall be obtained by summing the 12-month indices and dividing by twelve (12). 17.3 All calculations in this article will be carried to the fifth decimal place and rounded to the fourth decimal place. The following rules shall be used for rounding: 17.3.1 The fourth decimal place shall be rounded up when the fifth decimal place is five (5) or greater. 17.3.2 The fourth decimal place shall remain unchanged when the fifth decimal place is less than five (5).
