CONTRACT No: I-24-4979 Requests for Information Received from Plan Holders
Illinois State Toll Highway Authority Page 1 of 4 2/10/2025 Contract I-24-4979
The following are responses to questions received from Plan Holders no later than 2:00 pm local time on February 6, 2025. The responses below supersede any responses in Addendum No. 1 and Addendum No. 3.
Question No. 1: Reference Drawings 91,160 and 265. Each drawing is a detail for the 3ea prefabricated control building foundations. There are 3 pay items for the control building foundations, pay items JT131651, JT131652 and JT131656. However, it appears pay items 20700220, 50300300, 50200100, 50300225 and 50800205 are also for the same foundations.
