ASCE’s Outstanding Civil Engineering Achievement award – the OCEA – has recognized exemplary civil engineering projects every year since 1960.

This year, ASCE celebrates nine stellar projects as OCEA Honor Award recipients. These nine projects will be showcased during the ASCE 2021 Convention, Oct. 8 in Chicago. From the group of nine, two runners-up and the OCEA winner will be announced at the event.

Here are the 2021 OCEA Honor Award projects:
