ADDENDUM: CHIP SEAL PROJECT

Addendum #1 2021 Chip Seal Project

This addendum has been added to clarify some changes made concerning aggregate gradation.

In the IFB as it states on page 2: 

“The Chip Seal Program consists of applying asphaltic binder and aggregate meeting CDOT No. 8 specifications on approximately 14,610 square yards of street surface. A list of the streets scheduled to be chip sealed are included (see Street Listing). The City has a limited budget for the 2021 Chip Seal program and therefore reserves the right to adjust the quantities to fit within the financial limits of the program based on the bids received. The listed square yard measurements are estimates for bidding purposes only and the final square yard cost will be determined at the end of the project. “ 

Changes to the aggregate gradation requirements below: 

“The Chip Seal Program consists of applying asphaltic binder and aggregate meeting Type II (1/2” chip) specifications on approximately 15,210 square yards of street surface. A list of the streets scheduled to be chip sealed are included (see Street Listing). The City has a limited budget for the 2021 Chip Seal program and therefore reserves the right to adjust the quantities to fit within the financial limits of the program based on the bids received. The listed square yard measurements are estimates for bidding purposes only and the final square yard cost will be determined at the end of the project.”
