The Colorado Dept. of Transportation has been awarded $14 million to settle claims arising from damage to U.S. 36 north of Denver after part the highway collapsed in July 2019.

失败的高速公路部分当时只有三年的历史，这是由Ames Construction和Granite Construction的合资企业在2016年完成的一项主要高速公路升级的一部分。

The settlement says the bulk of the award, $6 million, will be paid by the Ames-Granite JV, with $4 million coming from HDR, the lead designer on the U.S. 36 project, and another $4 million from Kleinfelder Inc., one of the project engineers.

该协议于今年夏天早些时候达成，于8月6日首次公开。

The settlement document prohibits CDOT and the other parties from commenting on the final agreement but also assigns no blame for the incident. There were no injuries or accidents in the highway collapse.

The money will reimburse CDOT for most of the $17.6 million in emergency repairs to the highway, which were done by Kraemer North America on a CM/GC contract and took three months to complete.

根据CDOT的说法，维修包括拆除倒塌的高速公路细分市场，去除碎屑，钻孔和安装新的混凝土和钢支持结构。

The $3.5 million in costs not covered in the settlement included charges for the accelerated repair schedule and other materials, such as the geofoam blocks the agency elected to add to provide better structural support.
